Problems solved by technology

[0003] However, the cathode of the existing top-emitting structure uses light-transmitting materials, so the cathode resistance is relatively high, and the IR Drop effect produced by the cathode material with high resistance, that is, the voltage drop caused by the current and resistance, such as figure 1 As shown, the IR Drop effect will seriously affect the uniformity of the display panel's light emission

Abstract

The invention provides a display panel and a display device. The display panel and the display device comprise a substrate and a thin film transistor layer, a pixel layer and a cathode layer which aresequentially arranged on the substrate. The pixel layer includes a plurality of pixel units. Each pixel unit includes a target sub-pixel which is electrically connected with the cathode layer. The thin film transistor layer includes a plurality of cathode auxiliary lines and signal control lines which are alternately arranged in parallel. The target sub-pixel is arranged between the correspondingcathode auxiliary line and the signal control line. The signal control lines control the conduction situation between the cathode auxiliary lines and the target sub-pixel by transmitting control signals.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to the manufacture of display devices, in particular to an array display panel and a display device. Background technique [0002] Currently, OLED (Organic Light-Emitting Diode, organic electro-laser display) displays are divided into bottom emission structure and top emission structure, and the latter has the characteristics of higher pixel aperture ratio and longer pixel life than the former. [0003] However, the cathode of the existing top-emitting structure uses light-transmitting materials, so the cathode resistance is relatively high, and the IR Drop effect produced by the cathode material with high resistance, that is, the voltage drop caused by the current and resistance, such as figure 1 As shown, the IR drop effect will seriously affect the uniformity of the light emission of the display panel. [0004] Therefore, it is necessary to provide a display panel and a...
