Abstract

The invention provides an array substrate, a display panel and a display device. A touch control driving switch and a touch control detection line are arranged in the array substrate, a second sourceelectrode of the touch control driving switch is connected to a common signal line, and a second drain electrode of the touch control driving switch is connected to the touch control detection line; the upper portion of a second active layer of the touch control driving switch is not shielded by a light-shielding layer; when no touch control is conducted, light can be irradiated to the active layer of the touch control driving switch, and leakage current is large because of the light-sensitivity characteristic of the active layer; when a finger or a touch control pen conducts touch control, the light is shielded, the leakage current of the touch control driving switch becomes small, a signal of leakage current change is transmitted to a driving integrated circuit through the touch controldetection line, then the touch control position is recognized, and the low cost and thinning of the display device with the touch control device are easily achieved.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to an array substrate, a display panel and a display device thereof. Background technique [0002] Electrophoretic display uses the electric field between two electrodes (for example, the pixel electrode and the common electrode) to control the movement of electrophoretic particles in the electrophoretic film, and controls the reflection of incident light from the outside through the position of the moved electrophoretic particles, thereby realizing image display. . Due to its unique advantages such as extremely low power consumption, restoration of paper visual perception, and readability for human eyes, electrophoretic display technology has gradually attracted people's attention, especially in the field of static display (such as labels, books, newspapers, billboards, signs, etc.) brand, etc.), will become LCD (Liquid Crystal Display, liquid crystal display) and OL...
