Spliced Display Panel Pixel Layout for Narrow Bezel Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large-sized spliced display devices, the separation of light-emitting areas between adjacent display panels results in significant splicing gaps, severely affecting the display effect due to wider bezels.
Innovation Solution
The display panel design includes type-A and type-B pixel rows with specific arrangements of light-emitting devices and pixel circuits, where the second part of the type-A pixel circuit is moved from the outer side to the spacing area, reducing the upper bezel width and allowing for seamless splicing by adjusting the cutting distance between the panel edge and the pixel row.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If display panels with bezels are used in spliced display devices, then the panel structure is simple and easy to manufacture, but the light-emitting areas are separated by wider spaces forming obvious splicing gaps
Solution Approach 1:
The pixel circuits are divided into two parts: a first part located in the pixel row and a second part located in the spacing area. This segmentation allows the pixel circuit functionality to be distributed across both the light-emitting area and the bezel area, enabling the bezel to serve dual purposes as both structural support and functional circuit space.
Solution Approach 2:
The patent utilizes the spacing area (bezel) dimension to accommodate pixel circuit components. By placing the second part of pixel circuits in the spacing area rather than solely in the pixel row, the design transforms the previously wasted bezel space into functional circuit space, effectively reducing the visible gap without complicating the overall panel structure.
2Device complexity
If the pixel circuits are entirely located in the pixel row, then the circuit layout is simple, but the upper bezel width increases creating larger splicing gaps
Solution Approach 1:
The pixel circuit is segmented into a first part and a second part. The first part remains in the pixel row maintaining simple layout, while the second part is relocated to the spacing area. This segmentation reduces the upper bezel width by utilizing the spacing area for circuit components, thereby minimizing splicing gaps without significantly complicating the overall circuit layout.
3Ease of operation
If the second part of type-A pixel circuit is located in the pixel row, then the circuit arrangement is uniform, but the upper bezel width is increased
Solution Approach 1:
The pixel circuit is divided into a first part and a second part. The first part is located in the pixel row maintaining uniform arrangement, while the second part is positioned in the spacing area. This segmentation allows the uniform circuit arrangement to be preserved where needed while reducing the upper bezel width by utilizing the spacing area for additional circuit components.
Solution Approach 2:
Different parts of the pixel circuit are positioned in different locations with different characteristics. The first part is in the pixel row where uniform arrangement is important, while the second part is in the spacing area where space utilization is the priority. This local differentiation optimizes both uniformity and bezel width reduction.
4Ease of manufacture
If the spacing between adjacent display panels is increased, then the panel assembly is easier, but the splicing gap becomes more obvious
Solution Approach 1:
The patent utilizes the vertical dimension (spacing area between pixel row and panel edge) to accommodate pixel circuit components. By placing the second part of pixel circuits in the spacing area, the design reduces the horizontal bezel width without affecting panel assembly ease, thereby minimizing splicing gaps while maintaining assembly simplicity.
