Pixel Island Display Panel with Independent Control Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display technologies face challenges in achieving high refresh rates and resolution without increasing data transmission bandwidth and power consumption, leading to motion blur and ghosting, especially in demanding applications like VR and AR, which affects the immersive user experience.
Innovation Solution
The display panel design incorporates a substrate with scanning and data signal lines, sub-pixel units, and control units that allow for independent control of pixel islands, enabling differential refresh rates for focus and non-focus areas, utilizing transistors and signal lines to optimize data transmission and power allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the display refresh rate and resolution are increased, then the display quality is improved, but the data transmission bandwidth and power consumption are increased
Solution Approach 1:
The display screen is divided into multiple pixel islands, where each pixel island contains multiple sub-pixel units. Control units are introduced between adjacent pixel islands to independently control different regions. This segmentation allows different refresh rates to be applied to different areas, enabling high refresh rates in focus areas while using lower refresh rates in non-focus areas, thus reducing overall power consumption and data transmission bandwidth requirements.
2Measurement precision
If the display refresh rate and resolution are increased, then the display quality is improved, but the data transmission bandwidth is increased
Solution Approach 1:
The display is segmented into multiple pixel islands with independent control. Each pixel island can be controlled at different refresh rates based on its importance or focus level. This allows the system to transmit data at high bandwidth only for critical regions while using lower bandwidth for less important regions, thereby reducing the overall data transmission bandwidth requirement while maintaining high display quality where needed.
3Use of energy by moving object
If conventional display refresh rates are used, then the data transmission bandwidth and power consumption are reduced, but motion blur and ghosting occur
Solution Approach 1:
Different regions of the display are assigned different refresh rates based on their local requirements. Focus areas that are more susceptible to motion blur and ghosting effects receive higher refresh rates to maintain image quality, while non-focus areas use lower refresh rates to save power. This local quality approach ensures that harmful effects like motion blur are minimized in critical regions without unnecessarily increasing power consumption across the entire display.
