Problems solved by technology

[0004] However, in practical applications, it is found that when the external environment is brighter, the brightness of the light transmitted from the non-display area is brighter. At this time, the brightness of the area on the display panel that originally displayed a darker image increases, and the contrast of the display panel decreases.
In addition, when the brighter light transmitted from the non-display area directly hits the human eye, it is easy to cause damage to the human eye

Abstract

The invention discloses a display substrate and a preparation method thereof, a display panel and a display device. The display substrate comprises a plurality of display areas arranged in an array and non-display areas located between the display areas, wherein a display structure is arranged in each display area and is used for displaying a picture; and the non-display areas are transparent, and photochromic graphics are arranged in the non-display areas and are used for adjusting the light transmittance of the non-display areas according to the illumination intensity of the received light. According to the display substrate, the photochromic graphics are arranged in the non-display areas and can adjust the light transmittance of the non-display areas according to the illumination intensity of the received light, so that the brightness of the area for displaying a relatively dark image originally on the displayed picture is not improved due to the influence of external ambient light in a high-brightness external environment, thereby effectively ensuring the contrast of the displayed picture and improving the display quality.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate and a preparation method thereof, a display panel and a display device. Background technique [0002] Transparent display technology refers to a display technology that can not only see the image displayed on the display panel, but also see the real scene behind the display panel. It is widely used in shop windows, booths, car windows, etc. [0003] Specifically, a transparent display panel often includes several display areas arranged in an array and non-display areas located between the display areas. The display areas are used for image display, and the non-display areas are used for light transmission. The user can observe the display picture provided by the display panel through the light emitted from the display area, and at the same time, the user can also observe the real scene behind the display panel through the light transmitted from the non-displa...
