Abstract

The invention provides a display device and a driving method thereof, the display device comprises a substrate, a reflective display layer and a self-luminous display layer, the reflective display layer and the self-luminous display layer are stacked on the substrate, the self-luminous display layer comprises a plurality of light-transmitting parts formed in the thickness direction of the self-luminous display layer, and the orthographic projection of the reflective display layer on the substrate covers the orthographic projection of the light-transmitting parts on the substrate. Therefore, external light can enter the reflective display layer through the light-transmitting part. In the embodiment of the invention, the ambient light incident into the display device can form a corresponding picture through the reflection effect of the reflective display layer, optical compensation of the image picture formed by the self-luminous display layer is realized, the energy consumption of the self-luminous display layer is further reduced, and the service life and standby time of the display device are prolonged. Moreover, the display brightness of the display device can be controlled through the matching adjustment between the reflective display layer and the self-luminous display layer, and the flexibility is high.

Description

technical field [0001] The present application relates to the technical field of display devices, in particular to a display device and a driving method thereof. Background technique [0002] In the existing display device technology, the display panel is mainly divided into two mainstream technologies of a liquid crystal display panel and an organic self-luminous display panel. Wherein, the organic self-luminous display panel adopts organic electroluminescent material, and when a current passes through the organic electroluminescent material, the luminescent material will emit light, thereby realizing the display function of the display panel. [0003] During the use of the organic self-luminous panel, it is necessary to adjust the luminous intensity of the display panel according to the different intensity of external light, so as to meet the viewing requirements of human eyes. When the external light is strong, the display panel increases the magnitude of the current pas...
