Description
Technical field
The present invention relates to a kind of panel, particularly a kind of display panels.
Background technology
Generally speaking, liquid crystal indicator mainly is made up of display panels, structure of polarized light and backlight module; Just, last structure of polarized light can be arranged on the uper side surface of display panels, and structure of polarized light can be arranged between the downside and backlight module of display panels down.
When the optical interference of generation rule between backlight module and the display panels, can present dark-coloured ripples shape streakline in the display frame, this promptly be so-called " ripples line (Moire) phenomenon ".Particularly, when under the higher display mode of focusing level, or during with ash gray background, water ripple phenomenon is the easiest to be discovered.Therefore, must avoid the generation of water ripple phenomenon, so that the quality of image preferably to be provided.
Traditionally, can on backlight module, increase diffusion sheet or adjust brightness enhancement film, light source evenly be disperseed, as far as possible so as to reducing the generation of water ripple phenomenon.
With reference to Fig. 1, existing backlight module 10 is arranged on the below of display panels 20, and it comprises light source generator 11, reflecting plate (reflecting plate) 12, light guide plate (light guide plate) 13, diffusion sheet (diffusion sheet) 14 and at least one prismatic lens (prism sheet) 15.Wherein, light source generator 11 is in order to provide light source to display panels 20.The light upwards reflection of reflecting plate 12 in order to light source generator 11 is produced with the utilization rate of increase light, and then provides the output of brightness preferably.The light scatter that light guide plate 13 is used for light source generator 11 is produced is to diffusion sheet 14, to cause light via diffusion sheet 14 further scattering again, to provide display panels 20 more homodisperse light.In addition, generally can be provided with one or more prismatic lenses 15 in addition above diffusion sheet 14, with the difference of further correction irradiation intensity, the light that causes display panels 20 to receive can have irradiation intensity distributions uniformly.At this, quantity that prismatic lens is set and the visual demand of order are changed.
Yet, use diffusion sheet will inevitably cause cost to increase, and cause the thickness of integral module to increase, and be not inconsistent with demand that slimming is made every effort in market now.
With reference to Fig. 2, another existing backlight module 10 adopts digonous eyeglass 15,16; At this, by the prism arrangement direction of first prismatic lens 15 and the prism arrangement direction of second prismatic lens 16 are intersected at a predetermined angle, to avoid the generation of water ripple phenomenon.Yet it need cooperate different display panels and backlight module, adjusts the crossing angle between digonous eyeglass, just can reach the effect of avoiding water ripple phenomenon to produce; Thus, promptly be unfavorable for the unification of material specification, and be difficult for obtaining crossing preferably angle.
Moreover, in TaiWan, China patent the 200502652nd publication number, a kind of special prismatic lens design is also proposed, can be used for controlling the optically-coupled on contact surface between between the two prisms sheet in the backlight module, avoiding the generation of water ripple phenomenon, and then provide high-quality image.But this design is comparatively complicated.
With reference to Fig. 3, in No. the 5280371st, United States Patent (USP), in backlight module 10, directivity diffusion sheet 17 is arranged between traditional Lang Baite (Lambertian) diffusion sheet 14 and the display panels 20, also light is evenly distributed with the briliancy that increases normal visual angle, wherein this directivity diffusion sheet 17 is made up of one or more lens matrixs (lens array); At this,, can avoid the generation of water ripple phenomenon by rotating this directivity diffusion sheet 17.Yet it also need cooperate different display panels and backlight module to adjust the anglec of rotation, so it is unfavorable for the unification of material specification, and is difficult for obtaining the anglec of rotation preferably.
Therefore, existing display device still has the space of improvement, with making simple, low-cost and not increasing under the condition of one-piece construction thickness, light source is evenly disperseed as far as possible, and avoid the generation of water ripple phenomenon, and then the quality of image preferably is provided.
Summary of the invention
