PMOLED screen splicing structure

Abstract

The invention discloses a PMOLED screen splicing structure. The PMOLED screen splicing structure is formed by a plurality of splicing units. Each splicing unit is formed by splicing at least two screen bodies. The shapes and sizes of the screen bodies are the same. Edges of each screen body to be spliced in any splicing unit are provided with a plurality of leading wires. Every two leading wires on the same edge provided with the leading wires are arranged at regular intervals. The leading wires of every two adjacent screen bodies are arranged in a crossed mode on the edges to be spliced. The two adjacent screen bodies in one splicing unit share a leading wire region. The splicing units are subjected to physical arrangement to form the screen splicing structure. According to the PMOLED screen splicing structure, the two adjacent screen bodies in one splicing unit share the leading wire region, so that the width of splicing gaps is reduced and the resolution ratio and the display effect are improved.

Description

technical field [0001] The present invention relates to a PMOLED (Passive matrix Organic Light-Emitting Diode, passive organic electroluminescent diode) splicing screen structure, especially a splicing screen that can not only ensure the resolution and display effect, but also reduce the splicing gap body structure. Background technique [0002] At present, large-size and high-resolution display screens are used in some occasions. Due to the limitation of PMOLED driving methods, a single screen body cannot meet the requirements of large-size, high-resolution display. However, due to the simple process of PMOLED, The production cost is low, so multiple PMOLED screens can be spliced ​​together to achieve large-size, high-resolution display. The current method of splicing PMOLED screens is mainly to put the ready-made single PMOLED screens together directly to achieve splicing, such as figure 1 shown. To obtain a good display effect for the splicing screen, the pixel spacing...

Problems solved by technology

To obtain a good display effect for the splicing screen, the pixel spacing inside the screen must be consistent with the pixel spacing between the screens. However, when designing a normal PMOLED screen, in order to match the driver chip, the leads of the screen are all It is designed on one side of the screen, and the narrowest lead is about 1.5mm. Therefore, if you want to keep the pixel pitch between the screens consistent with the pixel pitch inside the screen, you can use two methods. One is to increase the pixel pitch inside the screen. , the pixel pitch of this scheme will become larger, which will directly affect the splicing display effect and reduce the resolution; another scheme is to overlap the lead area of ​​one screen with the area without lead of another spliced ​​screen, such as figure 2 As shown, but this method will cause the two screens to not be on the same plane, and the more layers are stacked, the greater the gap will be, and the entire splicing module will become very thick, which will reduce the display effect
