Abstract

The invention discloses a touch display device and electronic equipment, and belongs to the technical field of display. The touch display device comprises a color film substrate, an array substrate and a liquid crystal layer, the color film substrate comprises a plurality of pixel units and a black matrix which are distributed in an array mode, the black matrix defines a first opening, each pixel unit comprises at least one pixel, the array substrate comprises a plurality of infrared detection units, and the infrared detection units are arranged in the first opening. The infrared detection units are in one-to-one correspondence with the pixel units, and orthographic projections of the first openings on the array substrate are at least partially overlapped with the infrared detection units. In the embodiment of the invention, the infrared detection unit is arranged on the array substrate, and the infrared detection unit is used for detecting the infrared rays radiated by the human body to realize touch position recognition, so that the detection precision is high; the problems of interference between a capacitive touch driving signal and a display driving signal and poor display caused by touch and display time division multiplexing can be avoided.

Description

technical field [0001] The present application belongs to the field of display technology, and in particular relates to a touch display device and electronic equipment. Background technique [0002] In recent years, mobile phone touch has experienced resistive touch, surface acoustic wave (ultrasonic) touch, infrared touch, capacitive touch and other solutions, and finally capacitive touch has become the most commonly used solution at present. Among the liquid crystal display module (Liquid Crystal Display Module, LCM) capacitive touch, the incell solution (the method of embedding the touch panel function into the liquid crystal pixel) is the most commonly used. The electrodes are used as touch electrodes. When a finger touches the surface of the LCM, the capacitance of the touch electrode is changed due to the capacitive effect, and whether there is a touch action is identified by detecting the change in capacitance. [0003] However, due to factors such as process design ...
