Abstract

The invention provides a display panel and a preparation method thereof. The display panel comprises a substrate and a thin film transistor device layer, wherein the thin film transistor device layercomprises an extension part, a fourth electrode layer and a first via hole, and the fourth electrode layer is connected with the extension part through the first via hole and forms a Schottky junctionstructure. The light receiving performance of each film layer in the display panel is effectively improved, the detection sensitivity of the infrared detection type display panel is improved, meanwhile, the preparation process of the display panel is simple, and the production cost is low.

Description

technical field [0001] The disclosure relates to the field of display panel display technologies, and in particular to a display panel and a method for manufacturing the display panel. Background technique [0002] With the continuous improvement of the display technology, the display technology of the liquid crystal display device is also developed accordingly, and the display device has been widely used in various electronic devices. [0003] Existing display panels not only need to have high resolution, wide viewing angle, and low power consumption, but also need to have other diversified functions, such as display panels that can perform human-computer interaction, infrared perception and detection, etc. Rich features and more. Currently, a display device with an infrared sensitive function has become one of the development directions. When preparing an infrared photosensitive functional display panel, polysilicon and amorphous silicon are usually used to prepare an ar...
