Functional and aesthetic direction. However, the display screens of mobile phones, digital cameras, digital cameras, notebook computers and desktop computers are indispensable human-machine communication interfaces, and the display screens of the above products will provide users with This brings more convenience to the operation. In recent years, most of the display screens on mobile phones, digital cameras, digital cameras, notebooks, and desktop computers have been dominated by liquid crystal display panels (LCD pane 1). However, since the liquid crystal display panel itself does not have a function of emitting light, A backlight module (back 1 ight module) must be provided under the panel to provide the surface light source required by the LCD panel, so that the LCD panel can achieve the display effect, and at the same time obtain sufficient brightness and contrast to achieve the display function. Yes, backlight modules are generally divided into two types: side light type and direct type. Among them, the side light type backlight module needs a light guide plate (1 ight guide plate) to convert the linear light source into a liquid crystal panel. Required surface light source, and the direct type backlight module does not need to be equipped with a light guide plate, and can directly provide the required surface light source for the LCD panel.
