Problems solved by technology

[0004] At present, the size of the LED used in the LED light source 02 is usually not less than 3mm, the light is concentrated, and it is easy to cause uneven light mixing
In order to ensure uniform light mixing, it is usually necessary to increase the backlight film, which will increase the light mixing distance; and the thickness of the LED is relatively large, which increases the thickness of the LED backlight module to a certain extent, which is not conducive to the development of light and thin liquid crystal display devices

Abstract

The invention provides an LED lamp panel. The LED lamp panel comprises: a circuit board; a LED chip array arranged on the circuit board and comprising a plurality of LED chips, wherein the LED chip array is electrically connected with the circuit board; and a packaging layer, wherein the packaging layer covers the LED chip array, wherein the packaging layer comprises a packaging adhesive. Based onthe LED lamp panel provided by the invention, the invention further provides a preparation method of the LED lamp panel and a display device. According to the LED lamp panel and the preparation method thereof and the display device, the LED lamp panel is high in light emitting efficiency, good in heat dissipation, small in LED chip size and uniform in light emitting, a thick and heavy traditionaltelevision backlight diaphragm can be removed, the light mixing distance is reduced, the ultrathin module design is achieved, and light and thin development of a backlight module is facilitated.

Description

technical field [0001] The present application relates to the technical field of liquid crystal televisions, in particular to an LED lamp panel, a preparation method thereof and a display device. Background technique [0002] A liquid crystal display device currently on the market usually consists of two parts: a liquid crystal display panel and a backlight module. Since the liquid crystal display panel itself does not emit light, it needs the light generated by the backlight module to display images normally, so the backlight module becomes an integral part of the liquid crystal display. [0003] In the backlight module, the backlight board is the core component used to provide the light source. In the prior art, the backlight board is usually a light bar with a strip structure, including a strip circuit board and a light source arranged on the circuit board, such as Set LED (Light-Emitting Diode, light-emitting diode) on PCB (Printed Circuit Board, printed circuit board)....
