Embodiment Construction

[0026] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] Such as figure 1 - Figure 8 Various schematic diagrams of the invention are shown. The invention provides a backlight module of an LED liquid crystal display, which includes a backboard, an LED light source assembly installed in the backboard, and the LED light source assembly includes several LED light strips (light strips), at least one LED light Strip (light strip), the light strip refers to the LED lamp welded on the copper wire or strip-shaped flexible circuit board with a special processing technology, and then connected to the power supply to emit light. It is named for its shape like a light strip when it emits light. . Such as Figure 5As shown, each LED light bar includes a substrate 9 and a plurality of LED illuminants 1 evenly distributed on the substrate 9, the substrate 9 is the basic material f...

Abstract

The invention discloses a backlight module of an LED liquid crystal display. The module includes a backplane and an LED light source assembly mounted in the backplane, wherein the LED light source assembly comprises a plurality of LED lamp strips, and each LED lamp strip comprises a base plate and a plurality of LED luminous bodies uniformly arranged on the base plate; each LED luminous body includes a bracket, a copper foil bonding pad mounted in the bracket, a red LED chip, a green LED chip, a blue LED chip, two or multiple bonding pads and package resins which package each LED chip in the bracket; the red LED chip is arranged on one bonding pad, and the green LED chip and the blue LED chip are connected in parallel, and arranged on another bonding pad or respective bonding pads. The backlight module can effectively send out a spectral structure which adapts to the requirement of a liquid crystal TV panel, provide the backlight energy supply of LED TV wide color gamut, improve the overall transmittance of an LED liquid crystal TV, improve the depth of field of the liquid crystal TV, reduce the power consumption of backlight, enhance the color contrast and solve other technical problems.

Description

technical field [0001] The invention belongs to the technical field of LED liquid crystal displays and relates to a backlight module of an LED liquid crystal display. Background technique [0002] LED liquid crystal display, its full name is LED backlight liquid crystal display. According to the principle of liquid crystal display, it shows different colors by refracting the light from the backlight source by the liquid crystal molecules. The liquid crystal molecules themselves cannot emit light, and it is mainly realized by the illumination of the backlight source. The backlight of most liquid crystal displays is CCFL (that is, we often say cold cathode ray tube), and its principle is similar to our fluorescent tube. The LED backlight is a new type of backlight used to replace CCFL. Since it is a substitute for CCFL backlight, what is the advantage of LED backlight over CCFL backlight? The first is more uniform light emission. Since the tubes of CCFL backlights are usua...
