Array substrate and detection method thereof and display device

Abstract

The invention discloses an array substrate and a detection method thereof and a display device. The array substrate comprises an underlayer substrate, a thin film transistor located on the underlayer substrate and a photosensitive layer located on the underlayer substrate; the photosensitive layer comprises a shading part, at least part of orthographic projection, on the underlayer substrate, of the figure of the shading part blocks the figure of an active layer of the thin film transistor, and the shading part is located on the side, deviating from a grid electrode, of the active layer of the thin film transistor. According to the array substrate, the shading part in the photosensitive layer is adopted for blocking the figure of the active layer, due to the fact that the photosensitive layer is illuminated with light rays, a photo-generated current can be generated, that is to say, the photosensitive layer can convert light energy into electric energy, the photosensitive layer has the certain light absorption effect, most of the light rays are absorbed by the photosensitive layer, light reflection of the shading part is reduced, and the influence on the display effect of the display device is reduced.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to an array substrate, a detection method thereof and a display device. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD for short) has the characteristics of small size, low power consumption, and no radiation, and occupies a dominant position in the current flat panel display market. For TFT-LCD, the array substrate and manufacturing process determine its product performance, yield and price. [0003] In order to prevent external light or light from the backlight from irradiating the channel region of the thin film transistor, thereby generating photogenerated carriers and affecting the performance of the thin film transistor, a shielding layer is also provided in the array substrate to prevent light from irradiating the channel region. The pattern of the shielding layer is generally consistent with the pattern of the channel region. However, in ...
