Abstract

The invention provides a color film substrate and a display device. The color film substrate comprises an underlayer substrate, a color film layer, a plurality of texture recognition units; the colorfilm layer is arranged on one side of the underlayer substrate and comprises a black matrix and a plurality of color filters; the plurality of texture recognition units are arranged on the underlayersubstrate, each texture recognition unit comprises a thin film transistor and an optical sensor, and the orthographic projections of the texture recognition units on the substrate are located in the orthographic projection of the black matrix on the substrate. The texture recognition units are designed on the color film substrate, so that the optical path between an optical sensor and the surfaceof a finger can be effectively shortened, an acquired optical signal is enhanced, and meanwhile, the noise of the optical signal transmitted between LCD layers is greatly reduced; and meanwhile, LCD light transmittance is not influenced.

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...
