A backlight light source assembly, a backlight module, a liquid crystal module, and a manufacturing method thereof

Abstract

The invention provides a backlight light source assembly, a backlight module, a liquid crystal module and a manufacturing method. The backlight light source assembly includes an FPC and a light emitting device, and also includes: a first adhesive layer, a smooth reflective film; the FPC includes a base material layer, a conductive layer, the conductive layer covers one side of the substrate layer, the conductive layer includes a circuit area and a welding area, the welding area includes a number of pads, the first adhesive layer covers the FPC, and the smooth reflective film is attached to the first adhesive layer. The light emitting device is welded on the pad in the welding area. Through the above technical solutions, the present invention solves the problem in the existing structure that the surface of the ink is rough and powder is easy to fall off, so that the light cannot be well injected into the backlight module and cause bright spots. By setting a smooth reflective film, the light can be directly reflected into the backlight module, thereby improving the utilization rate of light and improving the brightness of the backlight module.

Description

technical field [0001] The invention relates to the technical field of backlight modules, in particular to a backlight light source assembly, a backlight module, a liquid crystal module and a manufacturing method. Background technique [0002] With the popularization of smart terminals, the demand for ultra-thin, high-brightness, and large-screen applications continues to rise, and the requirements for the quality and brightness of backlight modules are also getting higher and higher. Future developments have very positive implications. [0003] Such as figure 1 , 2 As shown, it is a structural schematic diagram of the light source components of the commonly used backlight module at present. figure 2 for from figure 1 The cross section at A-A in the middle, from figure 1 , 2 It can be seen from the figure that the backlight module light source assembly includes FPC1 and light emitting device 2 , wherein FPC1 includes base material layer 11 , conductive layer 12 , doub...
