Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increase in the number of pixels in display apparatuses leads to increased power consumption and processing load, and existing technologies have limitations in reducing the data amount of display data, particularly in regions with small pixels.
Innovation Solution
A display apparatus is designed with varying sub-pixel circuits in different regions, utilizing small sub-pixel circuits for high-definition areas and larger sub-pixel circuits for low-definition areas, along with optimized signal and voltage control to reduce data amount and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of pixels is increased to enhance display quality, then display quality is improved, but power consumption increases
Solution Approach 1:
The patent applies local quality by implementing different pixel densities in different display regions. The central region uses high pixel density for high-definition display, while peripheral regions use lower pixel density. This allows the display to maintain high quality where needed while reducing overall power consumption and data processing requirements.
Solution Approach 2:
The display area is segmented into multiple regions with different resolution characteristics. By dividing the display into high-definition and low-definition zones, the system can optimize power consumption and data transmission by treating different regions differently, rather than applying uniform high resolution across the entire display.
2Measurement precision
If the number of pixels is increased to enhance display quality, then display quality is improved, but processing load increases
Solution Approach 1:
Different regions of the display are assigned different quality levels and processing requirements. The control circuit processes high-resolution data only for the central high-definition region, while peripheral regions receive lower-resolution data, thereby reducing the overall processing load while maintaining display quality where it matters most.
Solution Approach 2:
The display processing is segmented into different resolution zones. By separating the display into high-definition and low-definition regions, the system reduces the total amount of data that needs to be processed and transmitted, lowering the processing load on the control circuit and other system components.
3Measurement precision
If uniform high resolution is applied across the entire display, then display quality is improved, but data amount increases
Solution Approach 1:
The patent implements local quality by providing high-resolution display data only to the central region where it is most needed, while using lower-resolution data for peripheral regions. This significantly reduces the total data amount required for display while maintaining high display quality in the important central area.
Solution Approach 2:
The display data is segmented into high-resolution and low-resolution portions corresponding to different display regions. This segmentation reduces the overall data transmission and storage requirements by avoiding the need to transmit high-resolution data for the entire display area, thereby reducing the data amount while preserving display quality where it matters.

AI summary
A display apparatus includes a substrate, a plurality of pixels arranged in a display region on the substrate, and a control circuit configured to control a signal to be supplied to the pixel, wherein the display region includes a first region, and a second region surrounding the first region, a part of the first region is set as a third region changeable in position, the signal to be supplied to the pixel is controlled, so that a display resolution of a fourth region which is not the third region in the first region becomes lower than a display resolution of the third region, and a display resolution of the second region is set to a value equal to or lower than the display resolution of the fourth region by a circuit configuration of the pixel.
