Display Device - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240257779 titled 'Display Device
Simplified Explanation: The patent application describes a display device with a noise compensator circuit that helps improve the quality of the displayed images by compensating for noise in the sensing signals.
- The display device includes a display panel with pixels and a common electrode, a gate driver, a source driving integrated circuit, and a noise compensator circuit.
- The gate driver supplies gate signals to the pixels, while the source driving integrated circuit supplies data signals to the pixels and a common voltage to the common electrode.
- The noise compensator circuit receives sensing signals from sensing lines connected to the display panel, gate driver, or source driving integrated circuit. It generates inverted sensing signals by applying different gain values to the signals and then generates a noise compensation signal based on these inverted signals.
Potential Applications: 1. Consumer electronics such as smartphones, tablets, and laptops. 2. Public displays and digital signage. 3. Medical imaging devices. 4. Automotive displays. 5. Gaming monitors.
Problems Solved: 1. Improved image quality by compensating for noise in sensing signals. 2. Enhanced display performance. 3. Reduction of visual artifacts on the screen. 4. Better user experience with clearer images. 5. Increased reliability of the display device.
Benefits: 1. Higher quality displayed images. 2. Reduced noise interference. 3. Improved overall performance of the display. 4. Enhanced user satisfaction. 5. Increased reliability and longevity of the display device.
Commercial Applications: Title: Advanced Noise Compensator Circuit for Display Devices This technology can be utilized in various commercial applications such as: 1. Smartphone and tablet manufacturing companies. 2. Display panel manufacturers. 3. Digital signage companies. 4. Medical equipment manufacturers. 5. Automotive display system providers.
