OLED (organic light-emitting diode) two-sided display substrate, manufacturing method, and display

Abstract

The invention provides an OLED (organic light-emitting diode) two-sided display substrate, a manufacturing method, and a display. The substrate comprises the substrate, multiple OLEDs formed on the substrate and a light ray control unit arranged on at least one side of the OLEDs, wherein the projection of the OLEDs on the substrate is covered with the projection of the light ray control unit on the substrate; the light ray control unit can be switched between a light-transmitting state and a light-proof state; the display comprises the two-sided display substrate provided by any one of the embodiments of the invention; the manufacturing method comprises the steps of preparing multiple OLEDs on the substrate; and forming an electrophoresis unit on at least one side of the OLEDs, wherein the electrophoresis unit can be switched between a light-transmitting state and a light-proof state. According to the display substrate, the manufacturing method and the display provided by the invention, one-sided display, two-sided display and two-sided luminance regulation display can be realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED double-sided display substrate, a manufacturing method and a display. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display devices are self-luminous, do not need backlight, high contrast, thin thickness, wide viewing angle, fast response speed, applicable to flexible panels, and wide operating temperature. Features, is recognized as the mainstream technology of the next generation display, and has been favored by major display manufacturers at home and abroad. [0003] With the gradual diversification of electronic products, the double-sided display function has become the main feature of the new generation of electronic products, especially the display products in some public places. However, the double-sided display devices currently produced in the industry are usually assembled with two single-sided display panels f...

Problems solved by technology

[0004] However, the double-sided light-emitting panel facing the pasting process is cumbersome, the thickness is super thick, and the cost is high. It has become an inevitable trend to prepare adjustable double-sided light-emitting OLED display devices on the same substrate. The current double-sided light-emitting OLED display device anode and the cathode are transparent metals with high and low work functions, respectively

However, there are two problems in the OLED double-sided light-emitting display device of the prior art. First, it is impossible to selectively display only one side; Limits the commercial application of double-sided light-emitting OLED display devices
