Abstract

The invention relates to a liquid-crystal display television, a backlight module and a manufacturing method thereof. The manufacturing method of the backlight module comprises the steps that an LED flip chip is fixed to a carrier plate; a photic adhesive is applied around the LED flip chip, and an adhesive layer is formed around the LED flip chip; transparent film fits the LED flip chip, and the transparent film is arranged to be opposite to the carrier plate; a light blocking layer directly facing the LED flip chip is spread on the transparent film so as to form a luminous body; the luminousbody is attached to a backing plate. According to the manufacturing method, light emitted by the LED flip chip is mostly spread to the side face, and the effect that on the condition that no lens exists, and the light comes to a diffusion plate to achieve uniform glowing is achieved; finally, the luminous body is attached to the backing plate. Due to the fact that the lens does not need to be installed on the backing module obtained through the backing module manufacturing method, the overall thickness of the backing module is thinner.

Description

technical field [0001] The invention relates to the field of backlight module manufacturing, in particular to a liquid crystal television, a backlight module and a manufacturing method thereof. Background technique [0002] At present, LCD TVs on the market are divided into side-type LCD TVs and direct-type LCD TVs according to the distribution position of LED backlight sources. Among them, direct-type LCD TVs are popular among consumers for their high quality and low price. [0003] However, the backlight module of the direct-lit LCD TV needs to install an optical lens on the outside of the LED backlight to mix the light energy emitted by the LED backlight evenly. Since the optical lens has a certain thickness and a light mixing distance needs to be reserved, the backlight The overall structure of the module is thick. Contents of the invention [0004] Based on this, it is necessary to provide a liquid crystal television, a backlight module and a manufacturing method the...
