Description

Pixel structure and transparent display Technical field

The present disclosure relates to the field of transparent display technology, and in particular to a pixel structure and a transparent display.

Background technique

In recent years, liquid crystal displays (LCDs for short) have been widely used in various consumer products due to their unique performance. Nowadays, one of the new LCD markets is Transparent-LCD (T-LCD), whose transparency will bring a brand new visual experience, and it has attracted people's attention. Typical transparent LCD applications, such as embedded light boxes, can see the image displayed by the transparent LCD through external light. In addition, when the transparent liquid crystal device is switched to the light transmission mode, it allows people to see the scene or objects inside the cabinet. Generally, box-type transparent liquid crystal devices are used in the following equipment, such as vending machines, refrigerators, shopping window machines, and so on. Therefore, a liquid crystal display with a flat-panel transparent backlight module is more suitable for the development trend of consumer electronic devices.
