Abstract

The invention provides an array substrate, a display device and a temperature detection method and device, and belongs to the field of display. The array substrate comprises a plurality of pixel units, multiple grid wires, multiple data wires and at least one temperature sensing and detecting wire, each pixel unit is provided with a pixel electrode and a pixel circuit, wherein the pixel circuit comprises a first pole and a first transistor connected with the pixel electrode in the pixel unit, and at least one temperature sensing pixel unit is included in the pixel units; the grid electrode ofeach first transistor is connected with one of the grid wires; each pixel circuit is connected with one of the data wires; the second pole of the first transistor in each temperature sensing pixel unit is connected with one temperature sensing and detecting wire, and the pixel circuit in each temperature sensing pixel unit comprises a switching module which is configured into electrically connecting the data wire with the second pole of the first transistor when effective electrical level exists on the data wire. By means of the array substrate, temperature detection of the interior of a display screen can be achieved in a simple manner.

Description

technical field [0001] The present disclosure relates to the display field, and in particular to an array substrate, a display device, a temperature detection method and a device. Background technique [0002] Thin Film Transistor-Liquid Crystal Display (TFT-LCD) products have low power consumption, thin and easy to use, high brightness, high contrast, high response speed, no radiation, wide application range, high production yield, and easy Features such as integration and upgrading have become one of the mainstream technologies in the flat panel display industry. A large number of TFT-LCD products are used in smartphones, digital cameras, and electronic watches, as well as flat-panel TVs and display devices of various sizes. [0003] Temperature is one of the most important parameters in both macroscopic and microscopic electronics. For example, high temperature will accelerate the aging of electronic devices and have adverse effects on electronic products, and the chara...
