Abstract

The invention discloses a light source module. The light source module comprises an optical plate, a light source and a dimming liquid crystal panel, wherein the dimming liquid crystal panel and the light-emitting surface of the optical plate are arranged oppositely; the dimming liquid crystal panel comprises a first driving substrate, a second driving substrate and a liquid crystal material layer; the first driving substrate comprises a first substrate and a common electrode, and the common electrode is arranged between the first substrate and the liquid crystal material layer; the second driving substrate comprises a second substrate, a plurality of independent electrodes, a plurality of first signal connecting pads and a plurality of first wires, the independent electrodes, the first signal connecting pads and the first wires are arranged between the second substrate and the liquid crystal material layer, the independent electrodes are arranged in an insulated mode, and each independent electrode is electrically connected to one of the first signal connecting pads by using one of the first wires. The light source module reaches local dimming by means of the dimming liquid crystal panel. The invention also provides a display device using the liquid source module.

Description

technical field [0001] The present invention relates to a light source module and its application, and in particular to a light source module capable of realizing local dimming and reducing the thickness of a backlight module, and a display device using the light source module. Background technique [0002] The liquid crystal display device needs to illuminate the liquid crystal display panel through the backlight module to control the brightness of the image. In order to improve the contrast of the liquid crystal display device, the most commonly used method is to use a backlight module with local dimming function. The regional dimming technology mainly uses direct-lit backlight modules to adjust the brightness of light-emitting diodes (LEDs) in different regions to achieve the function of regional dimming. [0003] Generally speaking, the local dimming technology of the direct-lit backlight module needs to strike a balance between the thickness of the backlight module and ...
