Problems solved by technology

[0005] However, the transmissive LCD and OLED, which are often used as display screens for mobile products, have a clear picture indoors, but outdoors where the sunlight is strong, the transmissive LCD and OLED will be unfavorable for human viewing and viewing because the external ambient light is too bright. identify
At present, the usual solution is to increase the brightness of the display to facilitate viewing, but this solution will increase the power consumption of the display and accelerate the decay of the display life

Abstract

The invention discloses a display device and a driving method thereof, which are used for reducing the power consumption of the display and prolonging the life of the display when the ambient light is strong. The display device includes a first display, and a second display positioned on the first display; the first display includes an array substrate and a first substrate oppositely arranged, liquid crystal molecules positioned between the array substrate and the first substrate, and a liquid crystal molecule positioned near the first substrate The transparent electrode on the side of the liquid crystal molecules, the reflective layer electrode on the side of the array substrate close to the liquid crystal molecules; the transparent electrode and the reflective layer electrode are used to adjust the deflection of the liquid crystal molecules; A first electrode in the region, an organic light-emitting layer on the first electrode, and a second electrode on the organic light-emitting layer are set.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a driving method thereof. Background technique [0002] With the rapid development of display technology, traditional cathode ray tube displays have gradually faded out of the high-end display market in recent years due to their bulky size and severe radiation. They have been replaced by liquid crystal displays with low radiation, low power consumption, and thin and light , LCD), and liquid crystal displays can be divided into transmissive, reflective, and semi-transmissive and semi-reflective liquid crystal displays according to optical technology. [0003] Such as figure 1 As shown, the transmissive LCD includes an array substrate 11 and a color filter substrate 12 oppositely arranged, and a liquid crystal layer 13 located between the array substrate 11 and the color filter substrate 12 . The light 14 of the transmissive LCD comes from a backlight...
