Display Panel Booting Time Reduction via Conditional Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-emissive display apparatuses face image quality degradation due to pixel brightness deterioration, leading to increased booting times as they perform sensing processes to compensate for this degradation, causing user inconvenience.
Innovation Solution
A display apparatus and method that determine whether to perform a sensing process based on the power-off period of the display panel, allowing the system to skip the sensing process if the period is shorter than a preset time, and using stored compensation data to rapidly boot and display images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sensing process is performed to compensate for pixel brightness deterioration, then image quality is maintained, but booting time increases
Solution Approach 1:
The patent implements a dynamic sensing process that adapts to the power-off period duration. When the power-off period exceeds a threshold, the sensing process is performed to maintain image quality. When the power-off period is short, the sensing process is skipped to reduce booting time. This dynamic approach resolves the contradiction by making the sensing operation conditional rather than fixed.
Solution Approach 2:
The patent changes the parameter of sensing process execution based on the power-off period duration. By using the power-off period as a decision parameter, the system dynamically adjusts whether to perform sensing, thereby balancing image quality maintenance with booting time reduction according to actual operating conditions.
2Reliability
If a sensing process is performed every time the display panel is powered on, then pixel deterioration is compensated, but user convenience decreases due to delayed image display
Solution Approach 1:
The patent makes the sensing process dynamic by conditioning it on the power-off period duration. This resolves the contradiction by making the system adaptive - performing sensing only when necessary (long power-off periods) and skipping it when unnecessary (short power-off periods), thereby maintaining image quality while improving user convenience through faster booting when appropriate.
Solution Approach 2:
The patent implements a skipping mechanism where the sensing process is omitted when the power-off period is shorter than the threshold. This allows the system to rush through the booting process without the time-consuming sensing operation when pixel deterioration is likely minimal, thereby improving user convenience without significantly compromising image quality in such scenarios.

AI summary
A display apparatus for reducing a booting time includes: a display panel including a plurality of pixels; a timing controller configured to drive the display panel; and a at least one controller configured to control the timing controller to perform a sensing process for sensing electrical characteristics of the plurality of pixels based on power-on of the display panel, wherein the at least one controller is further configured to determine whether to perform the sensing process or skip the sensing process based on a power-off period of the display panel before the display panel is powered on.
