OLED (organic light emitting diode) display module and OLED spliced display screen with OLED display module

Abstract

The invention relates to the display technology of organic light emitting diodes, specifically to an OLED (organic light emitting diode) display module and an OLED spliced display screen with the OLED display module. The OLED display module comprises a substrate, an OLED structure used for generating OLED luminous pixels and a packaging layer used for packaging the OLED structure; and the substrate is a PCB (printed circuit board) substrate, wherein the OLED structure is arranged on the front side of the substrate, a wiring region connected with an external driving circuit is arranged on the back side of the substrate, contact wires corresponding to the OLED luminous pixels one by one are printed on the PCB substrate, and each of the contact wires is connected with the OLED structure at the position of the corresponding OLED luminous pixel, and is connected with the wiring region through the PCB substrate. According to the invention, a PCB is used as the substrate rather than a glass plate, and the existing non-luminous wiring region on the edge of the device is moved to the back side of the PCB substrate through leads of the contact wires, so that the non-luminous area of the device can be reduced, the splicing gap of the OLED spliced display screen spliced from the OLED display module can be greatly reduced, and the display effect of the screen can be well optimized.

Description

technical field [0001] The invention relates to an organic light emitting diode (OLED) display technology, in particular to an OLED display module and an OLED splicing display screen with the OLED display module. Background technique [0002] OLED is an organic light-emitting diode. It is a current-type light-emitting device based on organic materials. It has self-illumination, no backlight, all solid-state, ultra-thin, no viewing angle restrictions, fast response, wide operating temperature, and easy to realize flexible display. And 3D display and other advantages, is considered to be one of the most promising new FPD technologies. At present, the largest OLED screen that can be trial-produced is below 55 inches, and the OLED screens that are commercially put on the market are limited to 5-10 inches, and the size is small. Expensive raw materials. At present, splicing small-sized OLED display panels into large-sized display screens has great advantages in terms of technol...

Problems solved by technology

Since a non-luminous frame area is formed on the edge of the light-emitting display area 1: the sealing area 2 and the wiring area 3, when the OLED panels are spliced ​​into a large screen, there will be a splicing gap, and the image cannot be displayed in the non-luminous frame area, resulting in screen image distortion. Discontinuous, affecting the viewing effect

Many panel manufacturers are committed to improving the manufacturing process, but only relying on the improvement of the manufacturing process can only narrow the seam as much as possible, but cannot achieve the effect of seamless splicing
