Abstract

The invention relates to an OLED segment code display panel and a display device thereof, and the OLED segment code display panel comprises a substrate which comprises a display area and an edge area surrounding the display area; a first anode group on the display area of the substrate; a second anode group on the display area of the substrate; a cathode layer on the display area and on the first anode group and the second anode group; the first driving chip is electrically connected with the first anode group; the second driving chip is electrically connected with the second anode group; the circuit board is bound with the first driving chip and the second driving chip; and one end of the cathode connecting piece is connected with the cathode layer, and the other end of the cathode connecting piece is connected with the grounding end of the circuit board. According to the OLED segment code display panel, the problem that the first driving chip and the second driving chip are damaged due to large current when the first driving chip and the second driving chip are jointly and electrically connected with the cathode layer is solved, and the service life of the OLED segment code display panel is prolonged.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED segment code display panel and a display device thereof. Background technique [0002] The OLED display device is a new type of matrix stacked display light-emitting device. Its main structure is composed of an anode layer, an organic material layer and a cathode layer. The display is driven to emit light by an external electric field. In the prior art, in order to facilitate the wiring of the cathode connector, the cathode layer of the OLED segment code display panel is usually a whole, and the OLED segment code display panel usually has two or more driving chips. When the cathode layer is one As a whole, these driver chips need to be electrically connected to the same cathode layer, and the other end of the cathode connector electrically connected to the cathode layer is electrically connected to the common terminal of multiple driver chips. [0003] However, due to t...
