Problems solved by technology

LCD transparent display devices need backlight to provide brightness, so they need a higher aperture ratio, while OLEDs have lower luminous brightness, so the pixel units of these two display methods need as large an opening area as possible, so the area of ​​​​the light-transmitting area will be compressed. The transmittance of the display screen is very low; and because part of the display screen is used for light transmission and the other part is used for display, the display screen of the display screen has the problems of low contrast and poor quality clarity.

Abstract

The invention discloses a transparent display device which comprises a plurality of pixel units, and each pixel unit comprises a display area and a light-transmitting area. The micro light-emitting diodes with small sizes and high brightness are arranged in the display area, so that a large number of areas can be set as light-transmitting areas; an electrochromic device is arranged in the light-transmitting area, the electrochromic device is in a transparent state when the transparent display device is switched to the transparent display mode, and the electrochromic device is in a black light-proof state when the transparent display device is switched to the conventional display mode. In the transparent display mode, the electrochromic device becomes transparent, so that most of the area in each pixel unit can transmit ambient light, and the transmittance of the ambient light is improved; in a conventional display mode, the electrochromic device becomes pure black, the display contrast can be greatly improved, and then the display image quality is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a transparent display device. Background technique [0002] With the development of display technology, transparent display devices have gradually entered people's lives, such as transparent shop windows, transparent traffic signs, transparent watches, transparent vehicle displays, etc., with broad application prospects. [0003] The currently used transparent display devices generally display Liquid Crystal Display (LCD for short) or Organic Light-Emitting Diode (OLED for short), and a part of the light-transmitting area is added to the pixel unit to be used for passing through the environment. light to achieve transparent display. LCD transparent display devices need backlight to provide brightness, so they need a higher aperture ratio, while OLEDs have lower luminous brightness, so the pixel units of these two display methods need as large an opening area as possible, so the...
