Problems solved by technology

[0002] The light guide plate of the existing LED backlight panel is usually a flat plate, which has unsatisfactory astigmatism effect, and the light enhancement sheet located above the diffusion film is usually a planar structure, and the light extraction efficiency is not good
[0003] Due to the relatively high heat dissipation requirements of LED backlight technology, the thickness of the light guide plate of LED backlight panels currently on the market is generally 0.6mm, and the thickness of LED lamps is 0.6mm, resulting in a large overall thickness of the LED backlight panel, which seriously affects the LED backlight panel. Excellent heat dissipation efficiency and luminous brightness

Abstract

The invention relates to an ultra-thin LED backlight panel with good astigmatism, which comprises black and white double-sided adhesive tape, an upper diamond sheet, a lower diamond sheet, a diffusion film, a light guide plate, a plastic frame and a reflective film stacked sequentially from top to bottom. The top of the light guide plate is provided with a flexible circuit board, the flexible circuit board is provided with LED lights, the light guide plate is provided with bumps, and a number of parallel diamond-shaped columns are respectively distributed on the diamond pieces, and the two diamond pieces are The directions of the rhombic columns differ by 90°. Provided is an ultra-thin LED backlight panel with good astigmatism effect and good light extraction efficiency.

Description

technical field [0001] The invention relates to an ultra-thin LED backlight panel with good astigmatism, belonging to the field of electric light sources. Background technique [0002] The light guide plate of the existing LED backlight panel is usually a flat plate, which has an unsatisfactory light astigmatism effect, and the light enhancement sheet located above the diffusion film is also usually a planar structure, and the light extraction efficiency is not good. [0003] Due to the relatively high heat dissipation requirements of LED backlight technology, the thickness of the light guide plate of LED backlight panels currently on the market is generally 0.6mm, and the thickness of LED lamps is 0.6mm, resulting in a large overall thickness of the LED backlight panel, which seriously affects the LED backlight panel. Excellent heat dissipation efficiency and luminous brightness. Contents of the invention [0004] The purpose of the present invention is to overcome the d...
