Abstract

The present invention provides a color filter substrate and a display device. The color filter substrate includes: a base substrate; a color filter layer arranged on one side of the base substrate, including a black matrix and a plurality of color filters; a plurality of texture recognition units , set on the base substrate, each texture recognition unit includes a thin film transistor and a light sensor, wherein the orthographic projections of a plurality of the texture recognition units on the base substrate are located on the black matrix on the base substrate in the orthographic projection of . Designing the texture recognition unit on the color film substrate can effectively shorten the optical distance between the light sensor and the finger surface, enhance the collection of optical signals, and greatly reduce the noise of optical signals transmitted between LCD layers; at the same time, it does not affect the light transmission of LCD Overrate.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to a color filter substrate and a display device. Background technique [0002] The under-screen texture recognition technology can greatly increase the screen-to-body ratio of mobile terminals, and has become an important technical means for mobile terminals such as mobile phones to realize full screen. LCD (Liquid Crystal Display) is the current mainstream display product, featuring high output, low cost, mature technology, etc., and has broad market advantages. Realizing texture recognition under the screen on LCD is of great significance to the performance improvement of LCD products. However, due to the complex hierarchical structure of the LCD, problems such as low sensor sensitivity and poor recognition accuracy are faced in realizing the texture recognition function under the screen. [0003] Therefore, the texture recognition technology under the LCD screen still...
