Abstract

The invention provides a display panel, a display device comprising the same and a dead pixel processing method of the display panel. The display panel comprises a substrate and a plurality of pixel units, wherein the plurality of pixel units are arranged on the substrate in an array way, each pixel unit comprises a light-emitting region and a driving circuit region, in each pixel unit, the driving circuit region comprises a transistor, the light-emitting region comprises a first electrode, the first electrode is electrically coupled to a first pole of the transistor, and in a line direction or a row direction of the plurality of pixel units arranged in the array way, the light-emitting regions of two adjacent pixel units are adjacent to each other. The display panel also comprises maintenance auxiliary lines and insulation layers, the maintenance auxiliary lines are arranged between two adjacent pixel units, the insulation layers are arranged between the maintenance auxiliary lines and the first electrodes, and the maintenance auxiliary lines are configured to be in a way that the first electrodes of the two adjacent pixel units are electrically coupled when the driving of the light-emitting region of one of the two adjacent pixel units is unfavorable.

Description

technical field [0001] The present invention generally relates to the display field, and more particularly relates to a display panel, a display device including such a display panel, and a method for processing dead pixels of such a display panel. Background technique [0002] Organic light-emitting diode (OLED) display technology is a technology that uses reversible discoloration generated by organic semiconductor materials driven by current to realize display. OLED displays are ultra-light, ultra-thin, high brightness, large viewing angle, low voltage, low power consumption, fast response, high definition, shock resistance, bendable, low cost, simple process, use less raw materials, high luminous efficiency and temperature range Wide and other advantages, it is considered to be the most promising new generation display technology. [0003] In the manufacturing process of the OLED display device, the yield rate is one of the main factors affecting the manufacturing cost a...
