Abstract

The invention provides a display panel and a drive method, and a display device. The display panel comprises a substrate, a light emitting structural layer, a phase regulating layer and a reflective layer that are overlaid in sequence, wherein the phase regulating layer is used for performing phase regulation on a first light from the light emitting structural layer so as to obtain a second light,the reflective layer is used for reflecting the second light entering the reflective layer, the light emitting structural layer emits the first light and the first light enters the phase regulating layer, the phase regulating layer performs phase regulation on the first light so as to obtain the second light, the second light is reflected by the reflective layer and then is emitted from the display panel, so that holographic display is realized. The display panel provided in the invention realizes holographic display without using a backlight source and a large optical system, so that the volume of the holographic display is reduced, and the holographic display becomes lighter and thinner.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a driving method, and a display device. Background technique [0002] With the continuous development of display technology, three-dimensional display technology has gradually become a research hotspot. Compared with traditional two-dimensional display technology, three-dimensional display technology can present a more realistic and three-dimensional picture, thereby improving the accuracy and efficiency of people's information acquisition, processing, transmission and human-computer interaction. [0003] Holographic display technology is considered to be the ultimate solution for 3D display. The backlight of the existing holographic display adopts a laser light source or a light emitting diode (Light Emitting Diode, LED) light source plus a beam expanding collimating lens to expand and collimate the light source to illuminate the entire spatial light m...
