Prior art With the development of the industry, digital tools such as mobile phones, digital cameras, digital cameras, notebook computers, and desktop computers are all moving towards more convenient, versatile, and aesthetically pleasing directions. However, the display screens of mobile phones, digital cameras, digital cameras, notebook computers, and desktop computers are indispensable human-machine communication interfaces. The display screens of the above products will bring more user operations. convenient. In recent years, the display screens on most mobile phones, digital cameras, digital cameras, notebook computers, and desktop computers have been dominated by liquid crystal display panels (L C D p a n e 1). However, 'because the liquid crystal display panel does not have the function of emitting light', a backlight module (back 1 ight module) must be provided under the liquid crystal display panel to provide the surface light source required by the liquid crystal panel, so that the liquid crystal panel can achieve the display effect. , And at the same time get enough brightness and contrast to achieve the display function. It is worth noting that backlight modules are generally divided into two types: side-light type and direct-light type. Among them, the side-light type backlight module needs a light guide plate (1ightguidep 1 ate) to convert the linear light source into the surface light source required for the LCD panel, while the direct-type backlight module does not need to be equipped with a light guide plate. It can directly provide the surface light source required by the LCD panel.
