Embodiment Construction
[0008] An embodiment provided by the present invention: a method for shielding the backlight of a liquid crystal display. The frame of the backlight is made into a funnel shape, and the bottom of the funnel is an inclined plane. parallel state;
[0009] Then the parallel light is constrained by the parallel surface at the front of the funnel, and finally irradiated to the liquid crystal pixels.
[0010] Working principle: Because of the backlight interference, the light from the backlight is scattered after being emitted, which leads to mutual interference. The structure of the present invention corrects the light to a parallel state by forming a slope near the backlight, and then constrains it through the front parallel surface, thereby greatly Reduce backlight scattering and avoid backlight mutual interference.
[0011] It will be apparent to those skilled in the art that the invention is not limited to the details of the above-described exemplary embodiments, but that the ...
