Display Panel Gamma Tuning Using Cross-Area Register Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current gamma tuning process for display panels with increased refresh rates is lengthy, significantly reducing production efficiency due to the need for additional gamma tuning at new refresh rates.
Innovation Solution
A method that determines the target register value of a second display area based on a predetermined linear relationship with the first display area's register value, allowing direct calculation without additional tuning, ensuring no color deviation and reducing overall tuning time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If gamma tuning is performed on both the main screen and sub-screen separately, then the display quality of each area is ensured, but the gamma tuning time increases significantly
Solution Approach 1:
The patent applies the copying principle by using the gamma tuning results from the main screen as a reference to determine the gamma tuning parameters for the sub-screen. Instead of performing independent gamma tuning on both screens, the method copies the tuning approach from the main screen and adapts it to the sub-screen using a predetermined linear relationship between their register values, thereby reducing tuning time while maintaining display quality.
Solution Approach 2:
The patent utilizes parameter changes by establishing a predetermined linear relationship between the register values of the main screen and sub-screen. This linear relationship allows the conversion of gamma tuning parameters from one screen to the other through mathematical transformation, enabling efficient parameter adaptation without repeating the entire tuning process.
2Reliability
If additional gamma tuning is performed at new refresh rates, then the display performance at high refresh rates is improved, but the production efficiency decreases
Solution Approach 1:
The patent applies preliminary action by establishing the linear relationship between main screen and sub-screen register values in advance. This pre-established relationship allows for rapid determination of sub-screen gamma tuning parameters when new refresh rates are introduced, without requiring time-consuming additional tuning experiments, thus improving both display performance and production efficiency.
3Adaptability or versatility
If the number of supported refresh rates is increased, then the adaptability of the display panel is improved, but the gamma tuning time becomes longer
Solution Approach 1:
The patent implements universality by creating a general linear relationship model that can be applied across multiple refresh rates. Once the linear relationship is established, it serves as a universal tool for determining gamma tuning parameters at any refresh rate, eliminating the need to perform separate tuning for each refresh rate and thereby maintaining adaptability while reducing tuning time.

AI summary
A gamma tuning method, apparatus, and computer-readable storage medium. The gamma tuning method is applied to a display panel including a first display area and a second display area, and the gamma tuning method includes: acquiring a first register value of the first display area after gamma tuning under a target gray scale; and determining, according to the first register value and a predetermined linear relationship between register values of the first display area and register values of the second display area, a target register value of the second display area under the target gray scale.
