Organic light emitting display panel and manufacturing method thereof and organic light emitting display device

Abstract

The invention provides an organic light emitting display panel and a manufacturing method thereof and an organic light emitting display device, and relates to the technical field of display. The organic light emitting display panel comprises an organic light emitting display unit, a liquid crystal unit and a control unit, wherein the organic light emitting display unit comprises a flexible transparent substrate, a control array layer, a plurality of organic light emitting devices and a flexible packaging layer; the liquid crystal unit comprises a first transparent conducting layer, a polymer dispersed liquid crystal layer and a second transparent conducting layer which are arranged in sequence along a direction away from the organic light emitting unit; the control unit is electrically connected to the first transparent conducting layer and/or the second transparent conducting layer and is used for providing voltage for the first transparent conducting layer and/or the second transparent conducting layer. According to the technical scheme, the light transmission degree of the organic light emitting display panel can be adjusted, so that the privacy of a user can be protected conveniently, a contrast ratio of the organic light emitting display panel is improved, and a display effect is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to an organic light-emitting display panel, a method for manufacturing the same, and an organic light-emitting display device. Background technique [0002] With the vigorous development of flat-panel display technology, organic light-emitting display panels (Organic Light Emitting Display, OLED for short) are more and more widely used due to their excellent characteristics such as self-luminescence, high brightness, wide viewing angle, and rapid response. In order to meet some special requirements, there is an organic light emitting display panel with flexible and transparent display in the prior art, that is, both sides of the organic light emitting display panel can enter and exit light. [0003] The inventor found that the organic light-emitting display panel with flexible and transparent display in the prior art mainly has the following two deficiencies: First, th...

Problems solved by technology

[0003] The inventors found that the organic light-emitting display panel with flexible and transparent display in the prior art mainly has the following two deficiencies: first, the content displayed on the organic light-emitting display panel can be clearly seen on both sides, which is not convenient for protecting the privacy of users; Second, when one side of the organic light-emitting display panel displays images, the other side will have light incident on the organic light-emitting display panel, and this part of the light will exit from the display side, thereby reducing the contrast of the display image and causing poor display effect
