Abstract
The embodiment of the invention discloses an opposed substrate of an OLED (organic light emitting diode) array substrate as well as a preparing method and a display device thereof, and relates to the technical field of display. The opposed substrate, the preparing method and the display device have the advantages that a layer structure of the opposed substrate of the OLED array substrate can be simplified, the preparing difficulty of the opposed substrate is reduced, and further, the production qualification rate of the opposed substrate is improved. The opposed substrate of the OLED array substrate comprises a flat layer and a plurality of bulges positioned on the flat layer, wherein the flat layer and the bulges are conductors, and the bulges are electrically connected with electrodes of the OLED array substrate.
Description
technical field [0001] The invention relates to the field of display technology, in particular to an opposite substrate of an OLED array substrate, a preparation method thereof, and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) is an organic thin-film electroluminescent device, which has the advantages of simple preparation process, low cost, high luminous efficiency, easy formation of flexible structure, and wide viewing angle; therefore, the use of organic light emitting Diode display technology has become an important display technology. [0003] Generally, OLED display devices are divided into bottom-emission type and top-emission type. The array substrate of the top-emission type OLED includes a structure such as a metal anode, a metal cathode, and an organic layer between the metal anode and the metal cathode. The organic layer The emitted light exits the array substrate from the side of the metal cathode. [0004] In order to al...
