Spliced Display Panel Backplane for Seamless Large OLED Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing large-size spliced display screens have relatively large frames and complicated processes, making them unsuitable for large-size applications.
Innovation Solution
A spliced display panel is provided, comprising a display assembly with first connection terminals, a driving backplane with a communication circuit layer and second connection terminals, and a driving integrated circuit that transmits signals to the display assembly to drive it to emit light. This configuration reduces the number of splicing processes and allows for easy assembly of multiple small-sized display components into various shapes.

1Area of stationary object
If splicing technology is used to realize large-size OLED displays, then the display size can be increased beyond 20 inches, but the frame size becomes large and the process becomes complicated
Solution Approach 1:
The display system is divided into multiple independent display components that can be separately manufactured and then spliced together. Each display component includes a display substrate with connection terminals, and multiple components are arranged on a driving backplane. This segmentation allows large-size displays to be constructed from smaller modular units, reducing the complexity of the overall splicing process while enabling display sizes beyond 20 inches.

If splicing technology is used to realize large-size OLED displays, then the display size can be increased beyond 20 inches, but the frame size becomes large
Solution Approach 1:
Multiple display components are merged onto a single driving backplane that integrates the communication circuit layer and driving integrated circuit. The connection terminals of multiple display substrates are electrically connected to the driving backplane, allowing the display components to be controlled as a unified system. This merging approach enables large-size displays to achieve seamless splicing with minimal frame size, as the driving circuitry is shared across all display components rather than requiring separate frames for each component.
3Area of stationary object
If multiple small-sized display components are spliced together, then large-size seamless splicing display can be realized, but the number of splicing processes increases
Solution Approach 1:
The driving backplane serves multiple functions: it acts as a common mounting substrate for multiple display components, provides integrated electrical connections through the communication circuit layer, and houses the driving integrated circuit that controls all display substrates. This multi-functional design allows multiple small-sized display components to be spliced together with fewer distinct splicing processes, as the driving backplane unifies the connection and control mechanisms across all components, thereby improving production efficiency.
