With the continuous advancement of technology in the liquid crystal industry, the large size and thinness of liquid crystal display devices have increasingly become the mainstream demand of the market. Liquid crystal display devices generally include liquid crystal panels and backlight modules, and the structure of backlight modules is largely Determine the large size and thinning of the liquid crystal display device, so the narrow frame of the backlight module has become a trend; the current structure of the liquid crystal display device is shown in Figure 1, including the upper iron frame 101, the first display panel 102, the first Shading tape 103 , first optical film 104 , first light source 105 , first light guide plate 106 , first reflector 107 , plastic frame 108 , lower iron frame 109 , first circuit board unit 110 , and first housing 111 . Since the liquid crystal display mainly includes: a backlight and a liquid crystal display panel located on the backlight, the backlight includes a first light-shielding tape 103, a first optical film 104, a first light source 105, a first light guide plate 106, and a first reflection sheet 107 , plastic frame 108, iron frame 109. One of the determining factors of the frame width of the liquid crystal display is the distance between the edge of the liquid crystal display panel and the edge of the backlight source, that is, the frame width of the backlight source.
在目前的液晶显示装置当中，通常设置有上铁框、胶框、下铁框以及第一外壳，在背光单元中设置胶框和下铁框的目的是为了放置光学膜片和导光板，并且胶框和下铁框还可以防止导光板的漏光，下铁框用来固定胶框，而如果第一导光板漏光，则显示装置在显示的时候显示面板的边缘就会有亮线，影响良好的显示效果，因而在目前的设计中胶框和下铁框是必须的结构；同时，无论胶框、下铁框做的多么窄多么薄，也均会增加显示装置的边框大小，很难解决窄边框的问题。 Among the current liquid crystal display devices, an upper iron frame, a plastic frame, a lower iron frame, and a first casing are usually provided. The purpose of arranging the plastic frame and the lower iron frame in the backlight unit is to place the optical film and the light guide plate, and The plastic frame and the lower iron frame can also prevent the light leakage of the light guide plate, and the lower iron frame is used to fix the plastic frame, and if the first light guide plate leaks light, there will be bright lines on the edge of the display panel when the display device is displaying, which has a good effect Therefore, in the current design, the plastic frame and the lower iron frame are necessary structures; at the same time, no matter how narrow or thin the plastic frame and the lower iron frame are, they will also increase the frame size of the display device, which is difficult to solve The problem with narrow borders.
因此，如何能够很好的固定光学膜片，还能防止导光板漏光，同时最大限度的减小显示面板四周边框的宽度，使屏幕显示最大化，已经成为一个显示装置领域值得研究的问题。 Therefore, how to well fix the optical film, prevent light leakage from the light guide plate, and at the same time minimize the width of the borders around the display panel to maximize the screen display has become a problem worth studying in the field of display devices.
