DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18661883 titled 'DISPLAY DEVICE
Simplified Explanation:
This patent application describes a display device with a data driver that generates gamma voltages for controlling luminance levels of displayed images.
- The data driver includes a controller that generates a gamma voltage control signal based on target luminance information.
- A gamma voltage generator produces gamma voltages within a specific voltage range corresponding to the target luminance level.
- A decoder then uses these gamma voltages to generate data signals for grayscale values in the displayed image.
Key Features and Innovation:
- Controller generates gamma voltage control signal based on target luminance information.
- Gamma voltage generator produces gamma voltages within a specific voltage range.
- Decoder uses gamma voltages to generate data signals for grayscale values.
Potential Applications:
This technology can be applied in various display devices such as TVs, monitors, and smartphones to enhance image quality and control luminance levels effectively.
Problems Solved:
This technology addresses the need for precise control of luminance levels in displayed images to improve overall image quality and viewer experience.
Benefits:
- Enhanced image quality
- Improved control over luminance levels
- Better viewer experience
Commercial Applications:
