Abstract
Embodiments of the present disclosure provide a display device and relate to the display technology field. The display device includes: a first base substrate, a plurality of pixels arranged in an array, a light source, configured to emit visible light, at least one photoluminescence unit, configured to convert the visible light into invisible light, and at least one light sensing element, configured to perform fingerprint recognition according to the invisible light reflected by a touch body. The display device implements the fingerprint recognition with the invisible light, and then the influence on the fingerprint recognition caused by the visible light from the external environment or backlight source and irradiated onto the light sensing element is avoided, thereby improving a fingerprint recognition precision.
