Embodiment Construction

[0030] Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various aspects of the present invention Modifications in equivalent forms all fall within the scope defined by the appended claims of this application.

[0031] Polymer dispersed liquid crystal, also known as PDLC (Plymer Dpersed Liquid Crystal), PDLC is a liquid crystal dispersed in an organic solid polymer matrix with micron-scale droplets, because the optical axis of the small droplets composed of liquid crystal molecules is in a free Oriented, whose refractive index does not match that of the substrate, when light passes through the substrate, it is strongly scattered by the droplets and presents an opaque opalescent s...

Abstract

The invention provides an OLED (Organic Light Emitting Diode) display and a manufacturing method of the OLED display. The OLED display comprises an upper substrate, an array substrate, multiple pixel regions and multiple photic regions, wherein each photic region comprises a lower electrode arranged on the array substrate, an upper electrode arranged below the upper substrate, and a PDLC (Polymer Dispersed Liquid Crystal) layer arranged between the lower electrode and the upper electrode. By forming the POLC layer between the pixel electrode and the pixel cathode, the ITO (Indium Tin Oxide) voltage on two sides of the PDLC can be regulated, and the regulation of transparency is achieved; and because the ITO is unsuitable for use as an organic light emitting layer cathode, the metal material is used as the organic light emitting layer cathode.

Description

technical field [0001] The invention relates to an OLED display and a manufacturing method thereof, in particular to a transparent OLED display and a manufacturing method thereof. Background technique [0002] Organic light-emitting diodes (Organic Light-Emitting Diode, OLED) do not need a backlight because of their self-luminescence, and because OLEDs have high contrast, thin thickness, wide viewing angle, and fast response, they can be used for flexible panels and use Excellent characteristics such as wide temperature range, simple structure and manufacturing process, etc., are considered to be the emerging application technology of the next generation of flat panel displays. Since OLED displays do not require polarizers and color filters, and are active light-emitting display methods, the transparent OLED displays produced have high transparency, and the transparency can reach more than 40%. [0003] figure 1 It is an existing transparent OLED pixel structure, each pixe...
