Embodiment Construction

[0031] The present invention provides a high-contrast transparent display device and its control method. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] No matter the existing transparent LED display screen is in the bright screen state or in the black screen state, more ambient light will be transmitted from the display area, which greatly reduces the contrast of the LED display screen.

[0033] Contrast refers to the measurement of different brightness levels between the brightest white and the darkest black in the light and dark areas of an image. The larger the difference range, the greater the contrast, and the smaller the difference range, the smaller the contrast. A good contrast is 120: 1 ...

Abstract

The invention discloses a high-contrast transparent display device and a control method thereof. The transparent display device comprises a transparent LED (Light Emitting Diode) display screen, a thin film transistor liquid crystal display screen that is arranged on the backlight side of the transparent LED display screen, and a controller that is used for controlling input signals of the transparent LED display screen and the thin film transistor liquid crystal display screen; the thin film transistor liquid crystal display screen is controlled to be closed by the controller so as to preventambient light from entering the transparent LED display screen, and therefore high-contrast display of the transparent LED display screen is achieved. According to the transparent display device, thecontrast ratio can be greatly improved on the basis that the transparency is kept, the contrast ratio is a very important factor in the display effect, the high-contrast-ratio display device has a better visual effect than a low-contrast-ratio display device, and the transparent display imaging effect can be greatly improved.

Description

technical field [0001] The invention relates to the field of display devices, in particular to a high-contrast transparent display device and a control method thereof. Background technique [0002] Transparent display devices are becoming more and more common in our daily life, and they have absolute advantages in some special fields. The structure of the existing transparent display device is usually as follows figure 1 and figure 2 as shown, figure 1 For side-emitting LED display, figure 2 For positive light-emitting LED display screens, the LEDs in the transparent display device are opaque, and the parts other than the LEDs are transparent parts. Such as image 3 and Figure 4 As shown, the light transmittance of the side-emitting LED display can reach (7.8-1.2) / 7.8=85%, and the light transmittance of the front-emitting LED display can reach (7.8-2) / 7.8=75%, which is other A level that is difficult for transparent technology to achieve. [0003] Such as Figure...
