Abstract
Embodiments of the present disclosure provide an array substrate, a display device and a spatial positioning method of a display device. The display device includes a base substrate, a pixel layer arranged at a side of the base substrate, a light source structure having a same light exit direction as the pixel layer, a processing element. The light source structure emits collimation invisible light, the pixel layer includes a plurality of sub-pixels and at least one sensing pixel arranged between the sub-pixels, the at least one sensing pixel receives reflected light of the collimation invisible light emitted by the light source structure and reflected by an object to be positioned, the processing element is coupled with the sensing pixel and the light source structure, a distance from the object to the display device is calculated according to relevant data information of the collimation invisible light and the reflected light.
