Problems solved by technology

At present, the most common small-sized organic light-emitting diode screens mostly adopt a top-emitting structure. For the entire cathode coverage of the display area, the organic barrier layer near the junction of the cathode and the anode should be flat, but due to the influence of the development of the organic barrier layer, the anode The cathode formed below is disconnected, so that the signal of the integrated circuit board cannot be transmitted to the anode of the display area, resulting in poor curling display

Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing.

[0021] Such as Figure 1-2 As shown, the display screen includes: an integrated circuit board (IC) and an organic insulating film (PLN) 3; wherein, a power signal line 4 (Vss) is arranged on the integrated circuit board. A plurality of grooves 5 are equally arranged on the organic insulating film 3 ( figure 2 ), the cathode (cathode) 2 is disposed on the organic insulating film 3, and the cathode 2 is buried in the groove 5 and is in contact with the power signal 4 wires. Make the organic insulating film 3 near the junction of the anode 1 and the cathode 2 flat, and the cathode 2 formed under the anode 1 will not be disconnected, so that the integrated circuit board signal is transmitted to the cathode 2 in the display area, and the panel display will not be defective.

[0022] In one embodiment, image 3 As shown, an anode 1 (Anode) is arranged on the cathode 2 , and t...

Abstract

The invention relates to the technical field of a display device and specifically relates to a display screen. The display screen comprises an integrated circuit board and an organic insulation film. The integrated circuit board is provided with a power supply signal line. The organic insulation film is uniformly provided with a plurality of grooves. A cathode is arranged on the organic insulation film. The cathode is embedded in the groove and makes contact with the power supply signal line, or an anode is arranged on the cathode, and the anode is embedded in the groove and makes contact with the power supply signal line. The organic insulation film near juncture of the cathode and the anode is allowed to be flat, and the cathode formed under the anode does not disconnect, so that the signals of the integrated circuit board can be transmitted to the cathode of a display region, and poor panel display is not caused. The anode gets narrow in width, and when the anode is embedded in the groove, the anode is separated from and discontinuous with the edge of the organic insulation film, thereby preventing the organic insulation film near the juncture of the cathode and the anode from being unflat after development of an organic barrier layer in the back-end process, and forming an under cut in the edge of the anode to disconnect the cathode.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a display screen. Background technique [0002] Flexible organic light-emitting diode display is a new type of display that makes thin-film transistors and organic light-emitting diodes on flexible and bendable substrates. At present, the most common small-sized organic light-emitting diode screens mostly adopt a top-emitting structure. For the entire cathode coverage of the display area, the organic barrier layer near the junction of the cathode and the anode should be flat, but due to the influence of the development of the organic barrier layer, the anode The cathode formed below is disconnected, so that the signal of the integrated circuit board cannot be transmitted to the anode of the display area, resulting in poor curling display. Contents of the invention [0003] In view of the deficiencies in the above problems, the present invention provides a displ...
