Electronic Apparatus Brightness Region Segmentation for Display Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display screen walls face challenges in maintaining uniform brightness and chromaticity when connecting multiple display panels, leading to quality issues in the integrated image due to manufacturing errors.
Innovation Solution
The electronic apparatus divides each display panel into regions with controlled brightness and chromaticity differences, ensuring that the average brightness and chromaticity between adjacent panels are within specific ranges, and adjusts the pitch of light-emitting elements to maintain image quality by cutting and reconfiguring panel edges, using low-reflection materials to reduce light reflection, and simplifying connections with cables.

Engineering Contradiction Analysis
1Area of stationary object
If multiple display screens are connected into a screen wall to display large-area advertisements, then the display area is increased, but the brightness and chromaticity uniformity deteriorates due to manufacturing errors in each display screen
Solution Approach 1:
The patent divides each display panel into multiple regions (first region, second region, third region, fourth region) with different brightness characteristics. By segmenting the display panels and assigning different brightness levels to different regions, the patent compensates for manufacturing variations and achieves overall uniformity across the screen wall.
Solution Approach 2:
The patent applies local quality by creating regions with different brightness characteristics within each display panel. The first and second regions have different brightness levels compared to the third and fourth regions, allowing each region to be optimized for its specific position in the screen wall assembly.
2Area of stationary object
If display screens are connected to form a screen wall, then the display area is increased, but the image quality deteriorates due to brightness and chromaticity differences between adjacent screens
Solution Approach 1:
The patent segments each display panel into multiple brightness regions, which allows for precise control of brightness distribution. This segmentation enables the patent to address brightness mismatches at the region level rather than the panel level, improving overall image quality.
Solution Approach 2:
The patent changes the brightness parameter across different regions of the display panels. By adjusting brightness levels in the first, second, third, and fourth regions, the patent compensates for manufacturing variations and ensures uniform appearance across the entire screen wall.
3Area of stationary object
If display panels are connected to increase display area, then the screen wall coverage is improved, but the assembly complexity increases due to the need to manage brightness and chromaticity differences
Solution Approach 1:
The patent segments the brightness control into discrete regions within each panel, which simplifies the assembly process. By pre-dividing panels into regions with specific brightness characteristics, the patent reduces the complexity of managing brightness uniformity across the entire screen wall during assembly.

AI summary
An electronic apparatus has a first region and a second region adjacent to the first region. The electronic apparatus includes a first light-emitting assembly including a plurality of first light-emitting units in the first region. The electronic apparatus includes a second light-emitting assembly disposed adjacent to the first light-emitting assembly. The second light-emitting assembly includes a plurality of second light-emitting units in the second region. A third region is included in the first region, a fourth region is included in the second region, and the third region is adjacent to the fourth region. The difference in percentage between the average brightness in the third region and the average brightness in the fourth region is less than the difference in percentage between the average brightness in the first region and the average brightness in the second region.
