Problems solved by technology

[0005] The inventors found that the current auxiliary cathode in the top-emitting AMOLED (passive organic electroluminescent diode) has poor electrical connection performance with the cathode, and there is often a problem that the auxiliary cathode cannot be effectively connected due to the ineffective connection.
Moreover, since the back plate and the cover plate need to be packaged in the box, there is a certain extrusion force at this time, so that the conductive material (such as ITO) arranged around the spacer is easily broken, and the auxiliary cathode and the cathode are disconnected. , cannot be effectively electrically connected, the auxiliary cathode cannot effectively function, and the broken ITO is also easy to crush the cathode (such as indium zinc oxide, IZO), causing black spots, which in turn reduces the performance of the organic light-emitting display panel and product quality. rate etc.

Abstract

The invention discloses an organic light-emitting display cover plate, a manufacturing method thereof, a display panel and a display device. Specifically, the invention provides an organic light-emitting display cover plate, which comprises a substrate; an auxiliary cathode disposed on the substrate; a spacer disposed on a side of the auxiliary cathode remote from the substrate, wherein the spacercomprises an electrically conductive material and the spacer is electrically connected to the auxiliary cathode. Thus, the auxiliary cathode and the cathode of the organic light-emitting display backboard can be electrically connected simply and conveniently by the spacer, the conductivity of the cathode is improved, and the performance of the organic light-emitting display panel is further improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to an organic light emitting display cover plate and a manufacturing method, a display panel and a display device. Background technique [0002] Organic electroluminescence (OLED) display technology is characterized by self-illumination, wide viewing angle, high contrast ratio, low power consumption, extremely high response speed, ultra-thin weight, flexible display, rollable screen, strong temperature adaptability, and simple manufacturing process, etc. Advantages, has become a research hotspot in the field of optoelectronic display technology. Top-emitting AMOLED (passive organic electroluminescent diode) can effectively solve the problems of reduced aperture ratio and display brightness reduction caused by complex TFT (thin film field effect tube) compensation circuits. The microcavity effect can also improve the color gamut of the AMOLED display and improve the displa...
