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

The present invention relates to a transparent display device, an electronic device using the transparent display device, and a display method for the display device and the electronic device. The display device includes: a liquid crystal module; and a backlight module, arranged at the lower part of the liquid crystal module, for providing illumination backlight for the liquid crystal module; wherein the backlight module further includes a light source unit for emitting illumination backlight; and a reflection unit for converting the light source unit The emitted illumination backlight is reflected toward the liquid crystal module, wherein the reflection unit has a first working state and a second working state. In the first working state, the reflecting unit reflects the illuminating backlight emitted by the light source unit toward the liquid crystal module and blocks the light from the light source unit. The light from the opposite side of the unit passes; and in the second working state, the reflection unit reflects the illumination backlight emitted by the light source unit toward the liquid crystal module, and allows the light from the opposite side to the light source unit to pass to reach the liquid crystal module.
