Display device, electronic device and display method

Abstract

The invention relates to a transparent display device, an electronic device utilizing the transparent display device, and a display method applied to the display device and the electronic device. The display device comprises a liquid crystal module and a backlight module which is arranged on the lower part of the liquid crystal module and used for supplying lighting backlight for the liquid crystal module. The backlight module further comprises a light source unit which is used for emitting lighting backlight and a reflecting unit which is used for reflecting lighting backlight emitted by the light source unit to the liquid crystal module. The reflecting unit has a first working state and a second working state. Under the first working state, lighting backlight emitted by the light source unit is reflected to the liquid crystal module by the reflecting unit, and passing of light from a side opposite to the light source unit is blocked; and under the second working state, lighting backlight emitted by the light source unit is reflected to the liquid crystal module by the reflecting unit, and light from the side opposite to the light source unit is enabled to pass so as to arrive at the liquid crystal module.

AI Technical Summary

Problems solved by technology

However, although the OLED display has the characteristics of no backlight, which makes the size and power consumption of the display device smaller than that of the ordinary backlight liquid crystal display, but the OLED display has a short service life compared with the LCD.

At present, OLED can only achieve about 5,000 working hours, which is obviously inferior to the current LCD, which can reach up to 10,000 working hours, especially when transparent display devices are used in department store display windows, refrigerator door perspectives, car front windshields, vending machines, etc. OLED-based transparent displays are often limited by their relatively short lifetimes in areas where long operating times are required

In addition, there is still a big problem with OLED, that is, the aging time is not synchronized, which means that the red, green and blue diodes decay at different speeds, which will cause the display image to be distorted

In terms of manufacturing process, mass production of transparent OLED display devices using large-size panels is also a challenge
