Abstract

The invention provides a dimming board and a display device. The dimming board comprises an upper substrate, a lower substrate and a liquid crystal layer arranged between the upper substrate and the lower substrate. The upper substrate comprises a first transparent substrate and a first conductive layer which are sequentially arranged. The lower substrate comprises a second transparent substrate and a second conductive layer which are sequentially arranged. When voltages are applied to the first conductive layer and the second conductive layer of the dimming board, the light transmittance of the dimming board is different from the light transmittance of the dimming board when the voltages stop being applied to the first conductive layer and the second conductive layer of the dimming board.The dimming board is applied to the display device, the brightness of the display device can be controlled, the differentiation performance of products can be enhanced, and the market competitivenessof the products is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a dimming board and a display device. Background technique [0002] With the development of display technology, various new technologies are constantly emerging, and transparent display technology has attracted more and more attention because of its transparent display panel and its unique applications. A transparent display device generally refers to a display device that can form a transparent display state so that the viewer can see the image displayed on the display device and the scene behind the display device. Transparent display devices have many possible applications, such as windows of buildings or cars and display windows of shopping malls. In addition to these large device applications, small devices such as handheld tablets can also benefit from transparent displays, for example, enabling users to view maps and see through the screen to what is ahead. [0003] It ...
