Abstract

An embodiment of the invention provides a display device and relates to the technical field of displaying in order to improve outdoor readability while indoor readability of the display device is unaffected. The display device comprises a display panel and an electrochromic panel disposed on the display panel. The electrochromic panel comprises an electrochromic unit which covers a whole display area of the display panel. The electrochromic unit is transparent and photoconductive when luminance of the surrounding is smaller than or equal to a preset value, and is stained and light-absorptive when the luminance of the surrounding is larger than the preset value.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] There are two main types of display devices in the prior art, one is a liquid crystal display device, and the other is an OLED (Organic Light-Emitting Device, organic electroluminescent device) display device. These display devices are mostly used in mobile phones, In multimedia products such as tablet computers and digital cameras, due to the portability of these multimedia products, users often need to take these products outdoors for use. [0003] When users use these products with display devices outdoors, the outdoor sunlight will reflect on the surface of the display devices, making it difficult for users to see the images displayed on the display devices. In order to improve the outdoor readability of the display devices, now In some display devices, transflective and transflective display devices have appeared, and...
