- 1. Field of the Invention
- The present invention relates to a computer, and more particularly, to a display unit of a portable computer.
- 2. Discussion of the Related Art
- In general, a liquid crystal display(LCD) device used for a computer such as a portable computer or for a portable display is shown in FIG. 1. Referring to FIG. 1, the LCD device includes a
liquid crystal panel 20, a back light unit, and adriving circuit board 23. The back light unit is comprised of aluminescent lamp 11, alamp housing 12 having a U-shape and surrounding thelamp 11, alight guide 13, areflector 14 reflecting the incident light from the horizontal direction to the vertical direction, aprotection sheet 15 contacting thelight guide 13, afirst prism sheet 16 and asecond prism sheet 17 set on the protectingsheet 15 and condensing the incident light from thelight guide 13 to some direction, adiffuser 18 diffusing the light from the first andsecond prisms viewing area 21 of theliquid crystal panel 20 with a certain viewing angle, and afirst support frame 19 supporting these elements. - FIG. 3 shows a cross-sectional view of the light-guiding
plate 13 showing a gradual thickness decrease in cross-section as it extends away from thelight source 11. Afluorescent lamp 11 as the light source is fixed at a thicker end of the light-guidingplate 13. When thefluorescent lamp 11 is turned on, thelight 23 from thesource 11 is reflected by thelamp housing 12 surrounding thefluorescent lamp 11. The reflected light transmits through the cross-section towards the other side (thinner end) of the light-guidingplate 13 as indicated by the arrows. Then, the light spreads all over the surface of the light-guidingplate 13 and reaches the display area 21 (FIG. 1) through thediffusion plate 18. At the same time, a thin film transistor formed on the liquid crystal panel controls a corresponding pixel according to the signals from the driving circuit 30 (FIG. 1) to selectively transmit the light which collectively realizes the display of images on the display area. - The liquid crystal display is usually combined with, for example, a notebook computer as an output screen. The following method is used to fix the liquid crystal display to a device such as a notebook computer.
- Referring to FIGS. 3a and 3 b, in a conventional liquid crystal display, a
ground supporting plate 30 is disposed on the first fastening-frame 19. Amounting hole 33 is formed through theground supporting plate 30 and thefirst fastening frame 19, as shown in FIG. 3b. Then, theground supporting plate 30 and the first fasteningframe 19 are fixed by ascrew 31 as shown in FIG. 3a. In other words, a liquid crystal display is fixed to a device such as a notebook computer so as to fasten thefirst fastening frame 19 and theground supporting plate 30 by a fastening element such as a screw. - However, the liquid crystal display becomes thicker due to the length of the screw according to the method as shown in FIGS. 3a and 3 b. Moreover, since the
mounting hole 33 for the screw is formed on the front surface of the liquid crystal display, the display area of the liquid crystal display becomes narrow. - According to the structure described above, the LCD device operates as follows. The light from the
luminescent lamp 11 is incident on the rear surface of theliquid crystal panel 20 through the back light unit. A control circuit placed on thedriving circuit board 30 controls the incident light on theviewing area 21 of theliquid crystal panel 20 to display images and characters. - FIG. 4 is a drawing showing a plan view of the final assembly structure of the conventional liquid crystal display device. FIG. 4 also shows the assembled result of a
second support frame 40,liquid crystal panel 20 and back light unit having an assembly structure for mounting to a portable computer. Thesecond support frame 40 is made of metal or plastic, and holds theliquid crystal panel 20 and the back light unit. Here, thedriving circuit board 23 is located behind the rear part of the back light unit connected to theliquid crystal panel 20 with a flexible film (not shown). - FIG. 5 shows the assembly structure of the
liquid crystal panel 20 andbody 60 of the portable computer in the conventional method. Thesecond support frame 40 is mounted to arear case 50 of the portablecomputer using screws 43 throughscrew holes 41. A front case(not shown) having a blank area adjusted to the viewing area is joined at therear case 50. That is, theliquid crystal panel 20 is mounted with therear case 50 by thescrews 43 locked in the normal direction of the display surface through thescrew holes 41 formed on that surface. Although not shown in the drawings, the front case is mounted on the LCD device, opening theviewing area 21 and covering the other parts. - In general, as the size of the portable computer is designed for easy movement, the same goes for an A4 copy sheet, for example. Therefore, the ratio of the viewing area to the whole surface area of the display and the thickness of the display device affect the quality of the portable computer. However, in a conventional portable computer,
screw holes 41 are located on edge portions of the display surface in order to join thesecond support frame 40 to therear case 50. As the display area has a screw frame area 42 (FIG. 4) for forming theholes 41, the ratio of the area of the LC panel to theviewing area 21 is reduced. - Furthermore, in the conventional portable computer, as the
screws 43 are locked to the liquid crystal display device and therear case 50 in the normal direction of the display surface, the display part is thick enough to form anassembly device 51 for thescrews 43, such asscrew holes 41. Thesecond support frame 40 is also large enough to have a space for supporting thescrew holes 41. Thus, it is difficult to reduce the weight of the portable computer. - Accordingly, a liquid crystal device is needed having a high viewing ratio of the display, low weight, and reduced thickness for a computer, such as a portable computer.
- Accordingly, the present invention is directed to a computer that substantially obviates one or more of the problems due to limitations and disadvantages of the related art.
- An object of the present invention is to increase the ratio of the viewing area to the whole area of a computer display.
- Another object of the present invention is to provide a thin, light weight display unit.

Therear case 500 and the liquidcrystal display device 700 are joined to each other by fastening devices such asscrews 430, which are locked to the second and third screw holes 410 b and 410 c. Although not shown in the drawings, thescrews 430 are also locked with the first screw holes 410 a. - In another embodiment, in order to join the
second support frame 400 and therear case 500, an adhesive device such as double-sided adhesive tape can be used instead of the second and the third screw holes 410 b and 410 c. This example has an added advantage in that no screws are needed which makes the manufacturing method easy. - In a further embodiment, the
rear case 500 and thesecond support frame 400 are jointed to each other using hooks and/or other suitable fastening devices including adhesives formed at inner sides of therear case 500. This embodiment also does not need fastening devices such as screws 430. - Accordingly, in the present invention, the assembling or fastening devices are located at the side surface of the display and not at the front or back side. The assembling devices are preferably screws, hooks or, adhesive materials, for example. The direction of the assembling devices is normal to the side surface of the display, that is, parallel direction with the front (viewing) surface of the display. Moreover, the assembling devices may be formed on the upper and lower sides of the display.
- Referring to FIG. 9, the liquid crystal display is mounted to the portable computer. One of the advantages of the portable computer according to the present invention over the conventional portable computer is the higher ratio of the viewing area. Because there are no fastening elements on the display surface, the outer frame of the display area of the present invention is narrower than that of conventional ones. Thus, the ratio of the viewing area can be maximized and the thickness of the display part is made thinner than that of conventional ones.
- Furthermore, as the volume of the frames of the present invention is smaller than that of conventional ones, the portable computer of the present invention is lighter. Additionally, as it is not necessary to have screws, the cost for manufacturing can be reduced.
- It will be apparent to those skilled in the art that various modifications and variations can be made in the computer having liquid crystal display of the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
