Temperature detection module, array substrate and display device

Abstract

The application relates to the technical field of display, particularly, relates to a temperature detection module, array substrate and display device. The temperature detection module can include: a first transparent substrate; a heat conduction substrate provided with a first surface and a second surface which are opposite, wherein the first surface faces the first transparent substrate, and the second surface deviates from the first transparent substrate and can be in contact with a component to be tested; a first phase transition layer positioned between the first transparent substrate and the heat conduction substrate and formed on the first surface; a reflective layer formed on the surface of the first phase transition layer facing the first transparent substrate, and having an air gap with the first transparent substrate; and a connecting structure connected with the heat conduction substrate and the first transparent substrate and arranged around the first phase transition layer and the reflective layer, wherein the heat conduction substrate can conduct heat of the component to be tested to the first phase transition layer, and the first phase transition layer can contract or expand at different temperatures so as to change the size of the air gap. The scheme has simple manufacturing process and lower cost.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a temperature detection module, an array substrate and a display device. Background technique [0002] With the continuous popularization of display devices such as mobile phones, watches, and wristbands, users have higher and higher requirements for them. They need not only display and call functions, but also other functions, such as temperature detection functions. However, traditional temperature detectors have complex structures, such as thermocouple thermometers, thermal resistance thermometers, etc. If they are integrated into the display device, the manufacturing difficulty and cost of the display device will be greatly increased. [0003] It should be noted that the information disclosed in the above Background section is only for enhancing understanding of the background of the application, and therefore may include information that does not form the pri...
