Display Panel White Sub-Pixel Polygon Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-resolution display panels face challenges in achieving consistent brightness due to the increase in thin film transistors, leading to reduced aperture ratio and increased power consumption, and traditional RGBW panels fail to enhance pure color brightness, resulting in abnormal display issues like white borders.
Innovation Solution
A display panel arrangement where white sub-pixels are adaptively distributed to form polygons with areas at least twice as large as those of other color sub-pixels, using sub-pixel rendering technology to adjust brightness and prevent abnormal displays.

Engineering Contradiction Analysis
1Measurement precision
If the resolution of display panel is increased, then the image quality is improved, but the aperture ratio is reduced and power consumption increases
Solution Approach 1:
The display panel is divided into different types of sub-pixels (first type with higher luminance, second type with lower luminance) that can be selectively activated. This segmentation allows the display to achieve high resolution while controlling power consumption by only turning on necessary sub-pixels for each pixel region, rather than activating all sub-pixels uniformly.
Solution Approach 2:
Different sub-pixels are assigned different luminance characteristics (first type with higher luminance, second type with lower luminance) to match local display requirements. This local quality differentiation enables efficient power distribution where higher luminance is only used where needed, reducing overall power consumption while maintaining high resolution display quality.
2Illumination intensity
If traditional RGBW display panel is used, then backlight transmittance is improved, but abnormal display occurs due to excessive brightness enhancement at edges
Solution Approach 1:
The patent applies local quality by differentiating sub-pixel luminance characteristics - first type sub-pixels have higher luminance for grayscale regions requiring brightness enhancement, while second type sub-pixels have lower luminance for pure color regions. This prevents excessive brightness enhancement at edges while maintaining improved backlight transmittance overall.
Solution Approach 2:
The display panel dynamically selects which type of sub-pixel to activate based on the content being displayed. For grayscale regions, first type sub-pixels are activated to enhance brightness; for pure color regions, second type sub-pixels are activated to prevent abnormal display. This dynamic adaptation resolves the contradiction between improved transmittance and display quality.

AI summary
A display panel including a plurality of sub-pixel repeating units is provided. The sub-pixel repeating units are repeatedly arranged on the display panel. Each of the sub-pixel repeating units includes at least one first color sub-pixel and at least one second color sub-pixel. On the display panel, the adjacent first color sub-pixels form a first polygon, and the adjacent second color sub-pixels form a second polygon. The area of the first polygon is at least twice the area of the second polygon.
