Splicing Screen Panel Layout for Seamless Pixel Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panels suffer from visual disruptions due to splicing joints between unit panels, which reduce the visual screen proportion and increase the size of splice joints, affecting the overall visual sense of the splicing screen.
Innovation Solution
A splicing screen design where the first unit panel's light-emitting device layer extends and overlaps the non-display area of the second unit panel, visually eliminating or weakening the impact of the non-display area and improving pixel spacing consistency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If unit panels are spliced together to form a splicing screen, then the display area is increased, but splicing joints are formed which affect visual sense and reduce visual screen proportion
Solution Approach 1:
The non-display area is extracted and relocated to the edge of the unit panel, away from the display region. This allows the display area to extend to the actual edge of the panel, eliminating the visual disruption caused by non-display areas within the display region while maintaining the splicing structure for increased display area.
Solution Approach 2:
The non-display area is repositioned from a central or intermediate position to the peripheral edge of the unit panel, utilizing the boundary dimension. This dimensional reorganization allows the display area to occupy the maximum visual region while the non-display area serves as a functional edge zone for splicing operations.
2Ease of manufacture
If non-display area is present between adjacent pixel units of different unit panels, then splicing structure is enabled, but distance between adjacent pixel units is limited and splice joint size is enlarged
Solution Approach 1:
The non-display area is localized to the edge region of the unit panel, distinct from the display area. This local differentiation allows the display region to maintain high pixel density and visual quality while the edge region accommodates the non-display area for splicing functions, resolving the conflict between splicing structure and pixel spacing precision.

AI summary
The present application discloses a splicing screen and a display device, which relates to a technical field of display. In technical solutions provided by the present application, structures of a first unit panel and a second unit panel that are mutually spliced in the splicing screen are improved. A first light-emitting device layer defining a display area AA thereof in the first unit panel overlaps a non-display area of the second unit panel for displaying, so as to visually eliminate or weaken visual influence of the non-display area on the splicing screen, lift restriction of the non-display area NA on spacing between adjacent pixel units of different unit panels in the splicing screen, and improve visual senses of the splicing screen.
