Problems solved by technology

[0003] However, since the transparent displays used in liquid crystal display (LCD) transparent display technology and organic light-emitting diode (OLED) transparent display technology have a certain degree of light penetration, the background on the back side of the transparent display will interfere with the picture displayed by the transparent display, for example When the pattern of the background on the back side overlaps with the picture displayed on the transparent display or presents a similar color, it is easy to cause the problem of unclear and low contrast of the picture displayed on the transparent display, and it will also cause visual fatigue of the human eye, etc. Negative impact
[0004] In addition, the liquid crystal display (LCD) transparent display technology relies on the background light as the display backlight. In some scenes such as cars or high-speed rail, the intensity of the background light varies with time and place, causing the brightness of the display screen to flicker, resulting in poor image quality. Problems with poor experience

Abstract

The invention relates to a display device with dynamic adjustment of a transparent backlight. The brightness of a frame is adjusted dynamically according to the irradiation intensity of an ambient light source, so that the brightness of the frame is stabilized within a preset range. The display device comprises an LED, an electronic control unit, as well as a TFT (thin film transistor) liquid crystal display layer, a liquid crystal layer, a ambient brightness module obtaining layer, a light guide plate layer and a variable light transmission film layer arranged in a laminated way directly, a light guide plate is connected with the LED, and the TFT liquid crystal display layer, the liquid crystal layer, the light guide plate layer, the variable light transmission film layer and the LED areelectrically connected with the electronic control unit. The TFT liquid crystal display layer is used to display the frame, and the liquid crystal layer enables penetrated light to be in a normally white light transmission state or a high-fog light transmission state. The display device can ensure that the brightness of the frame is within the stable preset range, the frame looks more uniform andattractive, and watching for long time tends not to cause visual fatigue.

Description

technical field [0001] The present invention relates to a display device, in particular to a display device that dynamically adjusts the brightness of a picture according to the illumination intensity of an ambient light source so that the brightness value of the picture is stable within a preset range. Background technique [0002] With the rapid development of display technology, transparent display has been widely developed and applied in various fields such as aircraft, high-speed rail, automobile, and home. Due to their different technical principles, the existing transparent display technologies can be divided into three categories: laser projection transparent display technology, liquid crystal display (LCD) transparent display technology, and organic light emitting diode (OLED) transparent display technology. Among these three types of transparent display technologies, laser projection transparent display technology belongs to the method of projection, while liquid c...
