Abstract

The invention relates to an array substrate, a preparation method thereof, and a display panel. According to the invention, the preparation method can achieve the quantitative production, and an arraysubstrate with at least the following advantages can be prepared: a coverage area can be protected from being polluted and damaged through a first protection layer; external light can directly irradiate a photosensitive layer through a second conductive layer, so that a photosensitive area of a light sensor is increased, and the light sensing efficiency is improved; meanwhile, a first conductivelayer can effectively prevent a backlight source from directly irradiating the photosensitive layer to avoid possible noise influence, so that the light sensor has relatively stable light sensing performance; a second protection layer can prevent extrusion damage to each layer when a finger presses the array substrate, thereby prolonging the service life; meanwhile, the phenomenon of relative dislocation of each layer is prevented, and the user experience is improved.

Description

technical field

[0001] The present invention relates to the field of display technology, in particular to an array substrate, a preparation method thereof, and a display panel. Background technique

[0002] With the development of the display technology, it becomes a trend to combine the touch technology with the display panel, that is, the integration of the touch panel and the display panel. In an exemplary touch display panel, a PS (Photo Spacer, spacer) is formed on a color filter substrate, an ITO electrode is formed on the PS, and an ITO electrode is correspondingly formed on the array substrate. When a user's finger presses the color filter substrate, the indium tin oxide electrode on the spacer and the indium tin oxide electrode on the array substrate are contacted and conducted to transmit the touch signal. However, because touch often causes dislocation of the upper and lower substrates (color filter substrate and array substrate), the dislocation phenomenon makes...
