Problems solved by technology

[0005] When the wiring method of the above-mentioned power signal line is used for a small-sized AMOLED, it can effectively improve the influence of the voltage attenuation on the power signal line on the display effect, and reduce the power consumption of the panel. However, as the size of the AMOLED increases, The wiring method of the above power signal line cannot effectively solve the influence of voltage attenuation on the display effect and the power consumption of the panel

Abstract

The invention discloses an active-matrix organic light-emitting display and a display device. A threadlike power supply signal wire in the prior art is redesigned and optimized in the way that the threadlike power supply signal wire is changed into a plurality of layers of electrically connected planar power supply signal electrodes covering the whole panel display area. Compared with a threadlike power supply signal wire in an AMLOED (Active Matrix / Organic Light Emitting Diode) in the prior art, the whole multi-layer planar power supply signal electrode can greatly reduce the resistance, so that IR drop caused when the power supply signal electrode transmits a power supply voltage signal is reduced, the influence on the display effect from the IR drop is effectively reduced and the power consumption of the panel is also effectively reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an active matrix organic electroluminescent display device and a display device. Background technique [0002] Organic electroluminescent display device (OLED, Organic Light-Emitting Display) refers to the phenomenon that organic semiconductor light-emitting materials are driven by an electric field to cause light emission through carrier injection and recombination. Its luminescent principle is to use indium tin metal oxide (ITO, Indium Tin Oxides) transparent electrode and metal electrode as the anode and cathode of the device respectively. Under a certain voltage drive, electrons and holes are injected from the cathode and anode to the electrons and holes respectively. In the hole transport layer, electrons and holes migrate to the light-emitting layer through the electron and hole transport layers respectively, and meet in the light-emitting layer to form excitons to excite ...
