Problems solved by technology

Normally, when displaying a darker image, the light transmittance of the pixel is below 0.5%. At this time, due to too little transmitted light, the background behind the display device can hardly be seen clearly, and it is difficult to effectively realize transparent display. Effect
On the other hand, with the continuous change of the display screen, the grayscale value of the corresponding pixel is also in the process of constant change, and the change of the grayscale value will lead to a corresponding change in the light transmittance of different pixels, so that the user observed The background behind the display device changes light and dark in an orderly manner, seriously affecting the actual viewing effect of the user

Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] For a transparent display device, a key parameter that determines whether the transparent display effect is good or not is the light transmittance of the display device. Specifically, for each pixel, how to ensure the light transmittance of the pixel unit is to ensure the ability to The key to achieving a good transparent display effect. For traditional display devices, the display grayscale value of the pixel is usually directly related to the light tr...

Abstract

An embodiment of the invention provides a see-through display device and a driving method thereof, and electronic equipment, and relates to the technical field of displayers. The driving method of the see-through display device comprises the steps that the display gray-scale value of a display sub-region is obtained; according to the obtained gray-scale value of the display sub-region, the display gray-scale value of a compensation sub-region is obtained, and the compensation sub-region and the display sub-region are located in the same pixel region; according to the display gray-scale value of the compensation sub-region, a display signal is output to a pixel unit of the compensation sub-region, so that the sum of the light transmittance of the display sub-region and the light transmittance of the compensation sub-region is equal to preset light transmittance; the light transmittance of the display sub-region is a product of the average light transmittance of the display sub-region and the area of the display sub-region; the light transmittance of the compensation sub-region is a product of the average light transmittance of the compensation sub-region and the area of the compensation sub-region. By the adoption of the see-through display device and the driving method thereof, and the electronic equipment, changes of pixel light transmittance can be avoided, and a good see-through display effect is achieved.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a transparent display device, a driving method thereof, and electronic equipment. Background technique [0002] With the continuous progress of display technology, new display technologies are constantly being proposed and implemented by people, and transparent display products are such a new type of display products. Transparent display has a wide range of applications and can be integrated with technologies such as multi-touch and intelligent display. As a terminal for public information display, it is used in various fields such as department store display windows, refrigerator door perspectives, car front windshields, and vending machines. Display, interaction, advertising and other synergistic effects, transparent display products are attracting more and more attention in the field of special display due to their unique usage scenarios and intelligent scene switching.
