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 adverse effects on the display quality.
Innovation Solution
A display panel design with distinct first and second display regions, 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 is reduced
Solution Approach 1:
The patent uses Sub-Pixel Rendering (SPR) technology to generate virtual pixel information by copying and interpolating data from adjacent physical pixels. The processing circuit generates pixel data for the second display region by referencing pixel data from the first display region and adjacent areas, creating a virtual high-resolution image that maintains perceived resolution while using fewer physical pixels, thus improving light transmittance without sacrificing resolution.
Solution Approach 2:
The patent changes the parameter of pixel density distribution by creating a dual-density display structure. The first display region maintains normal pixel density while the second display region (under camera) uses reduced pixel density.配合 SPR algorithm, this parameter change allows the system to dynamically adjust effective resolution based on display needs versus light transmission requirements.
2Illumination intensity
If the pixel density in the second display region is reduced, then the light transmittance is improved, but the display effect is adversely affected
Solution Approach 1:
The processing circuit copies pixel data from the first display region and adjacent pixel regions to generate pixel data for the second display region. This copying mechanism ensures that the reduced pixel density area still produces visually acceptable image quality by reconstructing pixel information mathematically, thereby maintaining display effect reliability while improving light transmittance.
Solution Approach 2:
The processing circuit acts as an intermediary between the physical pixel array and the final displayed image. It processes pixel data through SPR algorithms to generate virtual pixel information that bridges the gap between reduced physical pixel density and the requirement for acceptable display quality, ensuring reliable display effect in the second display region.
3Measurement precision
If a dummy pixel space is formed in the second pixel row, then the resolution is enhanced through SPR technology, but the device complexity increases
Solution Approach 1:
The patent introduces a temporal dimension to the pixel arrangement by forming dummy pixel spaces in alternating pixel rows. This creates a time-multiplexed display structure where certain rows display actual pixel data while adjacent rows display generated/dummy data. The SPR processing circuit leverages this dimensional change to enhance resolution through algorithmic processing without proportionally increasing physical device complexity.
Solution Approach 2:
The display panel is segmented into different functional regions (first display region with normal pixel density, second display region with reduced pixel density) and different pixel row types (actual pixel rows, dummy pixel rows). This segmentation allows the system to apply different processing strategies to different segments, enhancing overall resolution through SPR while managing device complexity through localized rather than universal complexity increases.

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.
