Problems solved by technology

In addition to the electrodes, each light-emitting device includes at least a three-layer structure of an electron transport layer, a hole transport layer, and a light-emitting layer. The double-sided light-emitting display device designed in this way requires a lot of vapor-deposited multi-layer organic materials, many process steps, and process costs. High; and it is also necessary to evaporate the electrode material between the organic materials, which may damage the organic material during the evaporation of the electrode material, causing defects
Therefore, there are many defects in the double-sided display device of the prior art

Abstract

The invention discloses an organic light-emitting display device. The device comprises an array substrate. A first electrochromic layer, a second electrochromic layer and an organic light-emitting layer are arranged on the array substrate. The organic light-emitting layer is arranged between the first electrochromic layer and the second electrochromic layer. Through the selectively transparent or light-shielding function of the first electrochromic layer and the second electrochromic layer, the organic light-emitting display device realizes the single-sided or double-sided display.

Description

technical field [0001] The present disclosure generally relates to the field of display technology, and in particular, relates to an organic light emitting display device. Background technique [0002] With the development of display technology, organic light-emitting display devices are favored by mass consumers due to their high color gamut, high contrast and low power consumption. Most current organic light-emitting display devices such as mobile phones and televisions can only display on one side. At present, there are relatively few studies on double-sided display. figure 1 Existing solutions for double-sided display. see figure 1 , the double-sided light-emitting display device includes a substrate 01, two layers of light-emitting units 03 and three layers of electrode layers 02, that is to say, in the existing double-sided display, two light-emitting devices are connected in series. In addition to the electrodes, each light-emitting device includes at least a thre...
