Described screw 2 is for showing two kinds of colors;
Described display is according to display task, and the screw display in control electrophoretic fluid bath is current needs display color.
In the display that the embodiment of the present invention provides, because screw only need show two kinds of colors, therefore screw 2 only need arrange the color that two viewing areas show correspondence in its spheroid, thus can be reduced the production technology of screw, and technology maturation, with low cost.
The light that screw 2 involved by the embodiment of the present invention sends can be the light himself sent, also can be the light of its reflection, namely the embodiment of the present invention involved display can be active illuminant (display self produce light source, better in darker local display effect, as liquid crystal display, screw 2 involved in active illuminating escope can be printing opacity, and the electrode in electrophoretic fluid bath 1 also can be printing opacity, like this, light source can be arranged at base part, play the effect being similar to backlight.In addition, light source in display also can be arranged in the spheroid of screw 2, or the outer position of the spheroid being arranged at screw 2, but no matter light source is arranged at where, the current region needing the color place of display on the spheroid all requiring the light of light source to be only irradiated to screw 2) and reflection-type (display self does not send light source, and light source is surround lighting, display object is reached by reflection, under high light, show more obvious, as Electronic Paper) etc.
Screw 2 involved by the embodiment of the present invention, only for showing two kinds of colors and color, be similar to the black and white screw of prior art maturation, but the screw 2 in the embodiment of the present invention also not only shows black and white two kinds of colors, but can multicolour be shown, such as, red (R), green (G) in three pigments, blue (B) can also be even the colors such as yellow (Y), white (W).Further, screw 2 can utilize the half of its spheroid, and namely hemispherical area shows in two kinds of colors, and such as, screw 2 can be the colors such as R for episphere, and lower semisphere is the colors such as G.In the present invention's embodiment, screw 2 also can utilize the sphere being less than hemisphere to show a color.
Color in the embodiment of the present invention shown by screw 2, can meet the pixel requests such as three looks, four looks, the five colors or six looks.
The display that the embodiment of the present invention provides, different rotary ball 2 in electrophoretic fluid bath 1 can be arranged two kinds of different display colors, and according to the display task that will realize, screw display in control electrophoretic fluid bath is current needs display color, utilizes the collaborative colorize realizing screw 2 and show between pixel and screw 2.
In the embodiment of the present invention, the color layout on screw 2, can adopt the layout type such as bar shaped or alternating expression, below, be that example illustrates with R, G, B three primary colors three-color pixel:
Described bar shaped layout can be similar with existing conventional pixel layout, specifically can be as follows:
R G B R G B
R G B R G B
R G B R G B
Described alternating expression layout specifically can be as follows:
R G B R G B
B R G B R G
G B R G B R
As can be seen from above two citings, the embodiment of the present invention is preferably in embodiment, the current often kind of shown color of screw 2 can respectively surround by other two kinds of colors (i.e. the color of the current display of adjacent screw 2), in better embodiment, the embodiment of the present invention can also adopt a kind of pattern alternately occurred as red and green tint by pixel primary colors, to transmit the essential information of pixel.Blue pixel only provides the chrominance information of low resolution, and the visual characteristic of this and people adapts.
If adopt onesize RGB stripe shape layout as the layout format of sub-pixel, owing to being subject to the restriction of addressing mechanism, addressing capability only can bring up to twice; If adopt alternating expression and corrugated tile array (Pantile Matrix) as the layout format of sub-pixel, then laterally with longitudinally addressing capability all being made to double, 4 times can be improved altogether.In addition, alternating expression subpixel layouts form also has another advantage, namely its figure of presenting is symmetrical close to rotatory, therefore, if use it for wheeled apparatus, then display screen can rotate easily, sight can be watched from different directions depending on personnel, for the device that other are similar, if need according to shown information for see from different directions depending on personnel display screen is provided, also very convenient.
In the embodiment of the present invention, the principle of the color layout on screw 2 and the pixel layout of display more easily realizes more high-quality display, and realize based on the display task that display will realize.If a region will show same color, as a slice green tree leaf, be so reasonable in pixel (the i.e. screw 2) green that can show as much as possible of leaf region.Can whether identical the color that the screw 2 that the color that current screw 2 shows is adjacent shows is depends on display task (now need display identical or different) and screw 2 function (show identical or different color, relevant with color on screw 2).For RGB three primary colors pixel layout, bar shaped layout certainly will have more advantage than alternating expression layout display pure color, but alternating expression is easier to display enriches picture.General display wants to show pure color again can the high color of display resolution, preferably now that each color does not repeat distribution, and do not repeat with the color of adjacent screw 2 as far as possible, advantage is had more when such display rich colors, dynamic menu, shield other colors during display pure color, namely only allow and need the color pixel of display to show.So when pixel layout, convey pixel color difference that it connects as far as possible.Pixel layout not only bar shaped or alternating expression, also has triangle, five limits, hexagon in fact ... etc. layout format.
Screw 2 color layout form involved by the embodiment of the present invention, instantiation can as shown in accompanying drawing 2 to 5.As can be seen from accompanying drawing 2,3, in the embodiment of the present invention, the primary colors in pixel can be given successively on the screw 2 in a pixel bars (each screw 2 is endowed two kinds of primary colors), and primary colors recycles; As can be seen from accompanying drawing 4, in the embodiment of the present invention, screw 2 also can show a kind of primary colors with a viewing area in two color displays region, and another viewing area shows a basic look, as blue or white etc., further, a screw 2 is only required to show a kind of primary colors, and is given successively by the primary colors in pixel on different screws 2; As can be seen from accompanying drawing 5, in the embodiment of the present invention, shown by screw 2 two kinds of colors in one pixel bars, respectively at identical with in two kinds of colors shown by adjacent screw 2, so, screw 2 color layout shown in accompanying drawing 4,5 can roughly be summarized as: the color that a screw 2 can show is adjacent the color that screw 2 can show and at least there is a kind of identical color, and described is adjacent, can left and right also can be up and down etc.Certainly, the embodiment of the present invention can also comprise other color layout forms, and such as, in the embodiment of the present invention, display can adopt color membrane substrates in prior art LCDs to enamel the arrangement mode of matrix, such as bar shaped or alternating expression pixel layout form.
By describing above and can find out, the display that the embodiment of the present invention provides, be easy to the pixel layout realizing optimizing.And because each pixel has at least double-colored Presentation Function, make more intelligent changeableization of the layout of pixel color, reach better effect.Relative to prior art, the embodiment of the present invention makes spinning ball pixelation owing to have employed, and utilizes its cooperative effect to realize the technological means such as colored display, improves the display effect that screw 2 shows, improves the problem of screw 2 display color dullness.
Due in the display that the embodiment of the present invention provides, only require that screw 2 shows two kinds of colors, therefore, screw 2 spheroid only need be arranged color corresponding to two viewing area displays, so, suitably can reduce the spheroid of screw 2 in the embodiment of the present invention, but too much influence can not be caused to the display effect of screw 2.Just because of the spheroid volume of screw 2 involved by the embodiment of the present invention can be smaller, therefore, more screw 2 can be set in electrophoretic fluid bath 1, the pixel of display can be increased, thus make the display effect of display more excellent.
In a specific embodiment of the present invention, as shown in Figure 6, display can also comprise:
Barrier bed 4, being arranged at above described electrophoretic fluid bath 1 and covering described electrophoretic fluid bath 1, described barrier bed 4 adopts light tight material to form;
Described barrier bed 4 is provided with light hole 41 above described screw 2 centre of sphere, is provided for the current light therethrough barrier bed 4 needing the color of display of screw 2, and stops the current light therethrough barrier bed 4 not needing the color shown of screw 2;
When display is according to display task, when controlling that screw display in electrophoretic fluid bath is current needs display color, described display specifically can show the color of screw 2 current the needs display appeared by light hole 41 and utilize barrier bed 4 to block the current color not needing display of screw 2.
The display that the embodiment of the present invention provides can utilize barrier bed 4 to block the current color without the need to display of screw 2, and only by the current color needing display of reserved space display screw 2, thus the variegated phenomenon that screw 2 may occur can be overcome, realize the display effect that display is more true to nature, homogeneous.
In one particular embodiment of the present invention, barrier bed 4 specifically can be arranged on the partition of (namely between two neighbors) between screw 2 that a screw 2 is adjacent, namely utilizes described partition as the stilt of barrier bed 4.Described partition can be used for separating each screw 2 (i.e. pixel) and preventing each pixel electrophoresis liquid 3 mixed flow.
Screw 2 involved by the embodiment of the present invention, can be immersed in completely in electrophoresis liquid 3, because screw 2 is when showing the color of current needs display, spherical part on the color place screw 2 of these needs display (hemisphere or be less than the region of hemisphere) can be placed in screw 2 the first half, and the light of the color of these needs display is outwards dispersed through electrophoresis liquid 3.Therefore, by means such as photoetching in the embodiment of the present invention, the position be in by barrier bed 4 directly over screw 2 is removed, thus is formed light hole 41, and screw 2 needs the light of the color of display outwards can be dispersed by light hole 41.
In the embodiment of the present invention, the size of light hole 41, can be relevant to the color of the current display of screw 2 region on screw 2, be also appreciated that the size of region vertical projection on barrier bed 4 is relevant on screw 2 to the color of the current display of screw 2.In addition, the size of light hole 41 also can be formulated based on actual needs, but need guarantee that display there will not be variegated problem.
Barrier bed 4 involved by the embodiment of the present invention can adopt lighttight material to form, such as black photoresist, inorganic ceramic, or other materials etc.
The pixel in display is can be due to screw 2, the display area of itself is just very little, add again in the embodiment of the present invention light adopting lighttight barrier bed 4 to block the current color without the need to display of screw 2, the current light needing the color of display of screw 2 is appeared by means of only light hole 41, this may reduce the display brightness of display, and the display effect of display is shaded, therefore, in embodiments of the present invention, display can also comprise:
Amplifying device 5, for amplifying the current viewing area needing the color of display of screw 2, namely by the viewing area of the color shown by light hole 41.
Thus by strengthen screw 2 by the mode of the viewing area of the color shown by light hole 41 increase screw 2 current need display the brightness of color and display effect etc.Like this, the display that the embodiment of the present invention provides, by the barrier bed 4 that is provided with light hole 41 and amplifying device 5 with the use of, thus the mode by expanding viewing area strengthens display brightness and the display effect of display, and avoids occurring variegated problem.
Amplifying device 5 involved by the embodiment of the present invention, it specifically can be a kind of device with light scattering function.In a specific embodiment, amplifying device 5 as shown in Figure 6, can be provided with lighting surface 51 at it near barrier bed 4 side, for gathering the light of screw 2 by the color shown by light hole 41, and the light needing the color of display as current in screw 2; And barrier bed 4 side is being provided with scattering surface 52, the light scattering for being gathered by lighting surface 51 goes out amplifying device 5, thus strengthens display brightness and the display effect of display.
In this embodiment, size, the shape of amplifying device 5 can be formulated according to actual conditions, but need ensure that the light by screw 2 is launched by described light hole 41 gathers in whole or in part, and by the form of light scattering, the viewing area of screw 2 by the color shown by light hole 41 is amplified.In a specific embodiment, in amplifying device 5, lighting surface 51 can be made into concave spherical surface, and concave spherical surface covers spherical part screw 2 needing the color shown as far as possible, so that fully daylighting, be conducive to the function that amplifying device 5 better realizes amplifying the viewing area of the color of current needs display on screw 2 like this, certainly can not be too large, with the color avoiding lighting surface 51 to collect barrier bed 4, thus make display occur variegated problem.Meanwhile, the curvature of lighting surface 51 can not be too little, otherwise unfavorable expansion display viewing angles.In another specific embodiment, when described amplifying device 5 horizontal positioned, the size of lighting surface 51 vertical projection and area can equal the size of light hole 41.
Amplifying device 5 can be arranged at above barrier bed 4, or fits on barrier bed 4.In a specific embodiment, if when amplifying device 5 is a convex lens, then point-blank, namely amplifying device 5 can be arranged with light hole 41 is concentric in the axle center of the axle center of amplifying device 5 and light hole 41.
In order to avoid amplifying device 5 amplifies the color of display barrier bed 4, also the part of amplifying device 5 except lighting surface 51 and scattering surface 52 (53 parts as shown in Figure 6) can be made light tight or frosted finish effect, thus avoid display again to occur variegated problem.
It should be noted that, if display is reflection-type, then the light source of display is natural light, and so in this case, first the scattering surface 52 in amplifying device 5 can play the effect of lighting surface, gather natural light, and lighting surface 51 can be used as convergence face, the natural light gathered by scattering surface 52, through light hole 41, converges on screw 2, namely the effect of amplifying device 5 first for allowing the natural light in the display external world by scattering surface 52, lighting surface 51 and light hole 41, can illuminate screw 2.Then, when screw 2 reflects natural light, amplifying device 5 recurs to and amplifies the effect of screw 2 by the viewing area of the color shown by light hole 41, gather the light of screw 2 by the color shown by described light hole 41 by lighting surface 51, by scattering surface 52, the light scattering that lighting surface 51 gathers is gone out amplifying device 5.Foregoing description can be found out, because amplifying device 5 top and bottom and scattering surface 52 and lighting surface 51 are cambered surface, they have done twice convergence to the outer whole surround lighting of amplifying device 5 and natural light, so the brightness of beating the natural light on screw 2 is comparatively large, can not affect the brightness of screw 2.Because light path is reversible, when screw 2 reflects natural light, amplifying device 5 is equivalent to a light path means for diverging, by twice light path scattering of lighting surface 51 and scattering surface 52 two cambered surfaces, is exaggerated the viewing area of the color of the current display of screw 2.Namely amplifying device 5 is by arranging two cambered surfaces, thus can ensure daylighting and the reflected light process of reflective display.
In embodiments of the present invention, amplifying device 5 specifically can be the convex lens of acryl resin material, glass material or other materials.
In another specific embodiment of the present invention, as shown in Figure 7, the electrophoresis liquid 3 set by electrophoretic fluid bath 1, can also have light tight function.Display utilize electrophoresis liquid 3 block screw 2 current do not need to show color and show the color that current needs of screw 2 show.
When display is according to display task, when controlling that screw display in electrophoretic fluid bath is current needs display color, the display that the embodiment of the present invention provides blocks the current color without the need to display of screw 2 by adopting the electrophoresis liquid 3 with light tight function, and only show the color of current needs display in screw 2, thus when without the need to arranging barrier bed 4, overcome the variegated phenomenon that screw 2 may occur, realize the display effect that display is more true to nature, homogeneous.
Due to screw 2 show current need the color of display time, the part sphere (hemisphere or be less than hemispherical area) on the color place screw 2 of these needs display can be placed in the first half of screw 2 and the top of screw 2.Therefore, by controlling the amount of electrophoresis liquid 3 in electrophoretic fluid bath 1 in the embodiment of the present invention, or by controlling the modes such as the height of screw 2 in electrophoretic fluid bath 1, electrophoresis liquid 3 is exposed in current for the screw 2 color region of display that needs, and current for the screw 2 color region shown that do not need is immersed in electrophoresis liquid 3, utilize the electrophoresis liquid 3 with light tight function to block the current color not needing to show of screw 2, thus realize display and only show the color that current needs of screw 2 show.
The electrophoresis liquid 3 with light tight function involved by the embodiment of the present invention specifically can be inert chemi-cal reagent or general electrophoresis liquid etc. containing colored pigment, and colored pigment specifically can be black etc.Also inert chemi-cal reagent or general electrophoresis liquid can be processed through colouring in the embodiment of the present invention, make inert chemi-cal reagent or general electrophoresis liquid become the electrophoresis liquid with light tight function.
The pixel in display is can be due to screw 2, the display area of itself is just very little, add again in the embodiment of the present invention and adopt the electrophoresis liquid 3 with light tight function to block the current light not needing the sphere at the color place shown to send in screw 2, reduce the light-emitting zone of screw 2, and electrophoresis liquid 3 itself has other colors, therefore this may reduce the display brightness of display, and the display effect of display is shaded, therefore, display in this embodiment equally can by arranging amplifying device 5, amplify the current viewing area needing the color of display of screw 2
Like this, the display that the embodiment of the present invention provides, by the electrophoresis liquid 3 with light tight function and amplifying device 5 with the use of, thus the mode by expanding viewing area strengthens the display brightness of display, and avoids occurring variegated problem.
Equally, amplifying device 5 can be arranged at the top of screw 2, specifically can be arranged at there is certain distance apart from screw 2 the centre of sphere above (namely above screw 2 top), or fit be arranged at screw 2 the centre of sphere above.During display one color current due to screw 2, the region at this color place be shown can be present in the tip portion of screw 2 and the first half of screw 2, and therefore, amplifying device 5 can amplify the viewing area of the color that this is shown.In this embodiment, in amplifying device 5, lighting surface 51 may be used for gathering screw 2 and exposes that the spheroid of electrophoresis liquid 3 sends, the current light needing the color of display of screw 2; Scattering surface 52, may be used for the light scattering that lighting surface 51 gathers to go out amplifying device 5, thus strengthens display brightness and the display effect of display.In addition, be the color avoiding lighting surface 51 to collect electrophoresis liquid 3, it is excessive that the concave surface of lighting surface 51 is unfit to do, and meanwhile, the curvature of lighting surface 51 can not be too little, otherwise unfavorable expansion display viewing angles.In order to avoid amplifying device 5 amplifies the color of display electrophoresis liquid 3, also the part of amplifying device 5 except lighting surface 51 and scattering surface 52 (53 parts as shown in Figure 7) can be made light tight or frosted finish effect in this embodiment, thus avoid display again to occur variegated problem.
In addition, in order to prevent electrophoresis liquid 3 reflective (i.e. electrophoresis liquid 3 reflect ambient natural light), in the present invention's embodiment as shown in Figure 7, can be provided with equally:
