Since the brightness of the lcd tv depends on the brightness of the backlight, in the direct type backlight, the light source is located at the back of the lcd screen, behind the entire screen. The direct type backlight can achieve the effect of improving the brightness by improving the number of the LED lamp beads 31. The high-brightness television adopts high-power high-brightness LED lamp beads 31 and improves the density of the high-brightness LED lamp beads 31, realizes uniform light mixing, and achieves the aim of reducing the light mixing distance by reducing the thickness of the diffusion sheet 5 and the light increasing sheet 6.

The thickness required in the backlight chamber is reduced, and compared with the thickness between 30 and 50mm of the direct type backlight module applied to large-size display in the prior art, the thickness of the direct type backlight module can be reduced, so that the backlight module is lighter and thinner.
