A part of the light emitted from the light source 12 directly enters the light guide plate 11, and the other part is reflected by the lamp cover 13 and enters the light guide plate 11. After being transmitted through the light guide plate 11 and diffused by the diffusion sheet 15, the light is uniformly emitted, and then the prism sheets 16 and 17 are applied. Shoot at the LCD panel (not shown). However, there is a certain gap between the light source 12 and the lamp cover 13, and a part of the light is leaked and leaked from the gap, thereby reducing the brightness of the backlight system.
