Problems solved by technology
Because people only see a full white screen with naked eyes, and wearing glasses to watch in front of a white screen, people around will notice that the confidential information is not concealed enough
[0004] Therefore, when the user watches the confidential information in the display screen with anti-peeping function in the prior art, it is not concealed enough and is easily noticed by others.

Abstract
The invention discloses a display base plate, a display panel, a display device and a display system. The display base plate comprises a substrate base plate, a plurality of first sub pixels and second sub pixels, wherein the first sub pixels are positioned on the substrate base plate and are sequentially arranged; each second sub pixel corresponds to the corresponding first pixel; the first sub pixel and the corresponding second sub pixel have the same color; the light transmission wavelength range of the first sub pixels is different from the light transmission wavelength range of the secondsub pixel. The display base plate, the display panel, the display device and the display system provided by the invention have the advantage that the concealed performance and security when a user watches confidential information in the display device can be improved.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate, a display panel, a display device and a display system. Background technique [0002] With the continuous advancement of display technology, various types of display screens continue to emerge. From the perspective of effectively protecting commercial secrets and personal privacy, the design of anti-spy screens is very necessary. [0003] At present, the common method of display system with anti-peeping function is to separate the first polarizer on the light-incident side and the second polarizer on the light-outside of the display screen, and only install the first polarizer on the light-incident side, and place the first polarizer on the lens of the glasses. A second polarizer is set on the top to realize the function of anti-peeping. The polarization directions of the first polarizer and the second polarizer are perpendicular to each other, and ...
