With the advancement of electronic technology, especially the prevalence of portable electronic products in daily life, the demand for thin, thin, short, and low power consumption displays is increasing. Liquid crystal displays (Liquid Crystal Display; LCD) are often used in such electronic products because they have the advantages of low power consumption, low heat generation, light weight, and non-light-emitting displays, and have even gradually replaced traditional Cathode ray tube display. Conventional liquid crystal displays 10, for example, such as US Patent No. 6,380,998 issued to Arai on April 30, 2002, are entitled, LCD Device Having A Back Light) ", which is incorporated herein by reference, is shown in Figure 1. I The liquid crystal display 10 mainly includes a liquid crystal display panel 12 and a backlight module 20. The liquid crystal display The panel 12 includes two printed circuit boards (PCBs) 14 and 16 for carrying a package through a tape carrier.

Package; TCP) 18, which sends control and driving signals to the LCD panel 12. The backlight module 20 mainly includes a light source (not shown), a reflective film 24, a light guide plate 26, and an optical film 28 for uniformly emitting light emitted from the light source toward the liquid crystal display panel 12. The liquid crystal display i 0 further includes a metal frame 30 and a plastic frame 32 to receive the backlight module 20 and the liquid crystal display panel 12.

591358 V. Description of the invention (2) The combined LCD 10 is fixed on an external stand for installation on the end use such as a notebook computer. Referring to FIG. 2, it is shown that the liquid crystal display 10 of the prior art is fixed to an external bracket 50. The external bracket 50 and the metal frame 30 each have a hole, which are aligned with each other. The plastic frame 32 further has a threaded post 52 embedded therein. In this way, a bolt 54 can be screwed into the ridge pattern protrusion 52, so as to fix the liquid crystal display on the external bracket 50. However, in this configuration, since the plastic frame 32 requires an additional process to be embedded in the threaded stud 52, the manufacturing cost and man-hours of the liquid crystal display 10 are increased. In another alternative configuration, as shown in FIG. 3, the metal frame 30 has a threaded hole 56. The bolt 5 4 is screwed into the threaded hole 56, so that the liquid crystal display 60 is fixed on the external bracket 5. However, in this configuration, the screw inspection 54 is combined with the metal frame 30 instead of the plastic frame 32, so its strength and stability are poor. Furthermore, the threaded hole 56 has a protruding portion 58 which will interfere with the plastic frame 32 during installation 'to increase the difficulty of installation and design. In particular, when the liquid crystal display panel 12 is installed, the liquid crystal display panel 12 easily hits the protruding portion 58 of the metal frame 30, which causes the liquid crystal display panel 12 to rupture. In view of this, there is a need to provide a frame for a liquid crystal display, which can be stably fixed on an external bracket, and can overcome the above-mentioned shortcomings. B. [Summary of the Invention] An object of the present invention is to provide a stable fixing to an external On the bracket, the difficulty of the process. A kind of liquid crystal display frame, which can reduce

5913 ^ »5. Description of the Invention (3) In order to achieve the above-mentioned object, it includes a liquid crystal display mounting fixture. The liquid crystal display generates an image, and a backlight module case member is used for accommodating the liquid crystal wall to surround the case member. The at least one bolt of the frame having a generally flat profile is common to the external bracket. In summary, according to the present invention, the liquid crystal display was broken during the fixing process with a substantially flat wall. In addition, the frame member is fixed to the outside and can be firmly fixed to the outside. In order to make the above-mentioned manifestations of the present invention, the present invention will be described in detail below. The invention provides a liquid crystal display unit, a housing structure and a frame structure. The device has a liquid crystal display panel for illuminating the 9g- panel of the liquid crystal display surface. The display device. The frame member has a fixing member arranged on the shell member, a side and at least one threaded hole for inviting an ice rig, and an external supporting function to fix the liquid crystal display unit outside the Ming liquid crystal display unit. Therefore, the mounting panel on the LCD panel can avoid interference with the casing member, and the bolts of the external bracket pass through the frame casing member, so the LCD display element bracket. And other objects, features, and advantages can be more preferred embodiments, and in conjunction with the accompanying drawings for detailed description [Embodiment] Referring to FIG. 4, which shows a liquid crystal display unit 100 according to an embodiment of the present invention. The liquid crystal display unit 100 mainly includes a liquid crystal display device. A liquid crystal display panel 112 is used to display images and a backlight module 120 is used to illuminate the liquid crystal display panel 112. The liquid crystal display panel 112 includes two printed circuit boards (PCBs) 114 and 116 for transmitting tape.
