Abstract

The invention discloses a micro-LED display panel, a micro-LED pixel circuit and a display device, comprising a display area and a non-display area, the non-display area is located around the micro-LED display panel; Including a light-shielding layer, the light-shielding layer includes: a first light-shielding layer adjacent to the non-display area and a second light-shielding layer not adjacent to the non-display area; the non-display area includes VDD surrounding conductive lines and VSS Surrounding conductive lines, the VSS surrounding conductive lines surround the first light-shielding layer, the VDD surrounding conductive lines surround the VSS surrounding conductive lines; the VDD surrounding conductive lines and the VSS surrounding conductive lines The wires are connected to the chip-on-chip film through the bypass channel.

Description

technical field [0001] The present application relates to the technical field of displays, in particular to a micro-LED display panel, a micro-LED pixel circuit and a display device. Background technique [0002] In recent years, the display industry has developed rapidly, especially in my country, which has undergone earth-shaking changes. Through the introduction of technology, talents, advanced equipment, and innovation of core technologies, my country has become a major display manufacturing country in the world, and the display level has reached the world's leading level. It not only ended the dilemma of few screens in our country, but also led the trend of the display industry. [0003] The competition in the display industry is becoming more and more fierce, and the update cycle is shortening continuously. The competition between Liquid Crystal Display (LCD for short) and Organic Light-Emitting Diode (OLED for short) is particularly fierce. With the maturity of OLED...
