Method and device for driving night vision compatible display, night vision compatible display system, and mobile terminal

Abstract

Embodiments of the invention provide a method and device for driving a night vision compatible display, a night vision compatible display system, and a mobile terminal. The method for driving a nightvision compatible display screen comprises the following steps: determining a current display mode according to a user instruction or time information; when the current display mode is a night visiondisplay mode, detecting whether there is red data in the display data; when red data is detected in the display data, turning up the low data position of the green data in the display data to generatenight vision display data; and outputting the night vision display data to the night vision compatible display. By implementing the invention, the radiance integral mean of the display frames of thedisplay is reduced under the same brightness, thereby meeting the night vision use requirements. Compared with the conventional method of placing the optical filter on the display to realize night vision compatibility, the method provided by the embodiments of the invention does not affect the touch function of the display while implementing night vision compatibility, and does not cause inconvenience due to carrying the filter along.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a driving method, device, display system and mobile terminal for a night vision compatible display screen. Background technique [0002] Night vision compatibility performance means that in some environments where night vision equipment is required to be worn for observation, the light emitted by the display device must be compatible with the night vision equipment and not interfere with the normal use of the night vision equipment. [0003] As an all-solid-state self-luminous display technology, OLED has been widely used in various fields. However, if figure 1 As shown, due to the long wavelength of the red luminescent material of the OLED display screen, the wavelength span is 580nm ~ 710nm, the red field radiance of the screen is relatively high in the near-infrared part, and it is difficult to meet the red field index requirements of GJB 1394 night vision compatibility. It...

Problems solved by technology

However, if figure 1 As shown, due to the long wavelength of the red light-emitting material of the OLED display screen, the wavelength span is 580nm ~ 710nm, the red field radiance of the screen is relatively high in the near-infrared part, and it is difficult to meet the red field index requirements of GJB 1394 night vision compatibility. Causes people to be extremely dazzling when wearing night vision equipment to observe the red graphics on the OLED display

[0004] In order to solve the above problems, in the prior art, an optical filter for filtering red light is generally placed on the display screen, so that the light passing through the optical filter meets the allowable range of night vision equipment and human visual perception. way to inconvenience
