GAMMA VOLTAGE CORRECTION DEVICE AND GAMMA VOLTAGE CORRECTION METHOD FOR DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18455240 titled 'GAMMA VOLTAGE CORRECTION DEVICE AND GAMMA VOLTAGE CORRECTION METHOD FOR DISPLAY DEVICE

Simplified Explanation

The abstract describes a gamma voltage correction method for a display device with two display areas.

• Correct gamma voltage for each sub-pixel in the first display area based on measured light characteristics in different gray levels.
• Correct gamma voltage for each sub-pixel in the second display area based on measured light characteristics in the surrounding area and within the second display area in different gray levels.

Potential Applications

• Display devices such as TVs, monitors, and smartphones.
• Virtual reality headsets.
• Medical imaging displays.

Problems Solved

• Inaccurate display of colors and brightness levels.
• Uneven gamma correction across different areas of the display.
• Poor image quality due to incorrect gamma voltage settings.

Benefits

• Improved color accuracy and brightness uniformity.
• Enhanced image quality and viewing experience.
• Better performance in various lighting conditions.

Original Abstract Submitted

In a gamma voltage correction method for a display device including a first display area and a second display area, the gamma voltage correction method includes: correcting a gamma voltage for each sub-pixel of the first display area based on measured light characteristics of a first area of the first display area in a plurality of gray levels; and correcting a gamma voltage for each sub-pixel of the second display area based on measured light characteristics of a second area of the first display area around the second display area and measured light characteristics of the second display area in the plurality of gray levels.
