Recalibrating Gamma Curves for Seamless Transitions in Multiple Display Refresh Rates - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240135854 titled 'Recalibrating Gamma Curves for Seamless Transitions in Multiple Display Refresh Rates
Simplified Explanation
The patent application describes a method for adjusting the display panel's optical properties based on ambient brightness levels and refresh rates to reduce perceived optical defects.
- Measuring first and second values of an optical property at different ambient brightness levels for an input gray level and first refresh rate.
- Determining a compensation factor for the input gray level at the first refresh rate.
- Calculating a modified gamma value at a second refresh rate to maintain consistent optical property values between refresh rates.
- Storing the modified gamma value for adjusting display data during transitions between refresh rates.
Potential Applications
The technology can be applied in various display devices such as TVs, monitors, and smartphones to improve visual quality under different lighting conditions.
Problems Solved
The method addresses the issue of perceived optical defects in display panels when operating at different refresh rates and ambient brightness levels.
Benefits
The technology enhances the viewing experience by maintaining consistent optical properties across different refresh rates and ambient brightness levels, resulting in a more visually pleasing display.
Potential Commercial Applications
This technology can be utilized in consumer electronics, automotive displays, and other industries where display quality is crucial for user experience.
Possible Prior Art
One possible prior art could be methods for adjusting display properties based on ambient lighting conditions, but the specific approach of maintaining consistent optical property values between refresh rates may be novel.

The article does not discuss any potential limitations or scenarios where the modified gamma value may not effectively reduce perceived optical defects.
Original Abstract Submitted
a method involves measuring, for an optical property of the display panel for an input gray level and at a first refresh rate, first and second values at respective first and second ambient brightness levels. the method also involves determining a compensation factor for the input gray level at the first refresh rate. the method further involves determining a modified gamma value at a second refresh rate, wherein the modified gamma value reduces a perceived optical defect of the display panel when operating at the second refresh rate by maintaining a consistent delta difference in values for the optical property between the first and second refresh rates at different ambient brightness levels. the method additionally involves storing the modified gamma value, where the device is configured to adjust input display data using the modified gamma value when transitioning from the first refresh rate to the second refresh rate.
