Airborne display and method for widening color gamut of airborne display

Abstract

The invention discloses an airborne display and a method for widening the color gamut of the airborne display. The airborne display comprises a current source, a general control board, a key light guide board, a graphic board, a backlight source and a display screen, wherein the key light guide board, the graphic board, the backlight source and the display screen are coupled with the general control board; a working power supply is provided by the current source; the key light guide board is used for inputting a working state switching signal and electrically outputting the working state switching signal via a lead; the graphic board is used for generating a graphic picture signal and receiving an outside picture signal, and overlaps or zooms the graphic picture signal and / or the outside picture signal to obtain a display signal; the backlight source is used for generating a backlight signal; the general control board is used for transmitting the display signal, the working state switching signal, the backlight signal and a self-detection signal, and comparing the backlight source signal with initial data to correct the backlight source signal; the display screen is used for receiving and displaying the display signal.

Description

technical field [0001] The invention relates to the field of displays, in particular to an airborne display and a method for widening the color gamut of the airborne display. Background technique [0002] In recent years, aviation and aerospace, especially the rapid growth of LCD displays, especially put forward higher requirements for the display effect of LCD displays. The color gamut refers to the area formed by the colors that TFT-LCD can express, that is, the range of colors that TFT-LCD can express. The colors of the visible spectrum in nature constitute the largest color gamut space, which contains all the colors that the human eye can see. CIE (Commission International de L'Eclairag), the International Association of Illumination, has developed a method for describing the color gamut of TFT-LCD: CIE-xy chromaticity diagram. In the chromaticity diagram, the range of color gamuts that various display devices can represent is represented by a triangular area composed ...

Problems solved by technology

[0003] At present, the airborne LCD monitors used are all purchased from ordinary commercial LCD screens, and their performance is targeted to be improved according to the requirements of users, so that they can meet the specific requirements of users for the performance of the display screen. LCD screens are generally unable to automatically control the display. With the accumulation of working hours of the on-board display, the aging of the lights in the display, the shift of the spectrum, and the color shift problem of the display, the existing display cannot be controlled to solve such a problem. Then How to avoid color cast becomes an urgent problem
