Problems solved by technology

In the prior art, there are precedents of integrating photodetectors into liquid crystal display panels, but for the stray light interference from the backlight, most of them are shielded by filters, light baffles, etc., and the structure is complex and the process is difficult. Therefore, it hinders the implementation of technical solutions in practical applications

Abstract

The disclosure relates to a liquid crystal display device and a light detection method applied to the liquid crystal display device, and relates to the field of display technology. The liquid crystal display device includes: an array substrate and an opposite substrate arranged oppositely, and a liquid crystal layer between the array substrate and the opposite substrate; a first polarizer, located on the array substrate facing the opposite substrate one side of the substrate; a second polarizer located on a side of the opposite substrate away from the array substrate; and a photodetector disposed on the array substrate for detecting light intensity. The disclosure can improve the detection accuracy of ambient light intensity.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular to a liquid crystal display device and a light detection method applied to the liquid crystal display device. Background technique [0002] With the development of optical technology and semiconductor technology, flat panel display devices represented by liquid crystal display devices (Liquid Crystal Display, liquid crystal) have the characteristics of light and thin, low energy consumption, fast response speed, good color purity, and high contrast. occupied a dominant position. [0003] The basic principle of liquid crystal display is as follows figure 1 As shown, a liquid crystal layer 100 is provided between the array substrate 101 and the opposite substrate 102, the arrangement of the liquid crystal molecules in the liquid crystal layer 100 is controlled by an electric field, and the polarization state of polarized light is changed by the optical rotation of the l...
