Display Panel With Dummy Pixel Space for Camera-Region Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of an under-screen camera module in display panels reduces the pixel density in the corresponding display region, leading to lower resolution and adversely affecting the display effect.
Innovation Solution
A display panel design with a first and second display region, where the first region has a higher pixel density and the second region has a lower pixel density, incorporating a dummy pixel space and a staggered arrangement of sub-pixels, along with a Sub-Pixel Rendering (SPR) technology to enhance resolution while maintaining high light transmittance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the quantity of pixels is reduced on the display region corresponding to the under-screen camera module, then the light transmittance is improved, but the resolution at the display region deteriorates
Solution Approach 1:
The patent introduces a dummy pixel row between existing pixel rows, adding a new dimension to the pixel arrangement. This allows the display region to maintain higher resolution by creating virtual pixel positions through the dummy row, while the actual physical pixel density remains reduced to accommodate the under-screen camera and ensure light transmittance.
Solution Approach 2:
The patent creates dummy pixels that copy the functionality of real pixels in the pixel repeat unit. These dummy pixels are positioned in the added dummy pixel row and work together with existing pixels to form complete color sub-pixel groups (RGB), effectively copying the pixel function without requiring additional physical light-emitting structures that would block camera light.
2Illumination intensity
If the quantity of pixels is reduced on the display region corresponding to the under-screen camera module, then the light transmittance is improved, but the display effect deteriorates
Solution Approach 1:
The patent applies different pixel densities to different regions of the display. The display region corresponding to the under-screen camera uses a reduced pixel density with dummy pixels to maximize light transmittance, while other regions maintain normal pixel density. This local differentiation ensures each region has the quality needed for its specific function.
Solution Approach 2:
By adding the dummy pixel row as an additional dimension to the pixel structure, the patent enables the display region to achieve adequate display效果 with fewer physical pixels, thus improving light transmittance for the under-screen camera while maintaining acceptable display quality through the enhanced pixel arrangement pattern.
3Illumination intensity
If the pixel density is reduced in the second display region, then the light transmittance is improved, but the density of pixel units deteriorates
Solution Approach 1:
The patent segments the pixel structure into multiple components including real pixels, dummy pixels, and empty spaces within the pixel repeat unit. This segmentation allows the display region to use fewer actual pixel elements while compensating with strategically positioned dummy pixels, thereby reducing overall pixel unit density and improving light transmittance without completely sacrificing display capability.

AI summary
The present disclosure provides a display panel, a display device and a display driving method. The display panel includes a first display region and a second display region each including a plurality of pixel repeat units. Each pixel repeat unit includes a first sub-pixel in a first color, a second sub-pixel in a second color, a third sub-pixel in a third color and a fourth sub-pixel in the first color. A light-emitting area of each of the first sub-pixel and the fourth sub-pixel is smaller than that of the second sub-pixel or the third sub-pixel. A dummy pixel space is formed in a second pixel row between a first pixel repeat unit in a first pixel row and a second pixel repeat unit in a third pixel row in three adjacent pixel rows at the second display region.
