ENHANCED OVERDRIVE OR UNDERDRIVE FOR FLAT PANEL DISPLAYS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18358004 titled 'ENHANCED OVERDRIVE OR UNDERDRIVE FOR FLAT PANEL DISPLAYS
Simplified Explanation
- Devices and methods are provided to adjust display pixel luminance to compensate for pixel hysteresis due to previous frames.
- An electronic device includes a display panel and processing circuitry.
- The processing circuitry generates image data for the display pixels and takes into account the pixel history of each pixel.
- By analyzing the current frame value and the pixel history, the processing circuitry determines a compensated value to drive each pixel to achieve the desired luminance.
Potential Applications
- Consumer electronics with displays (e.g., smartphones, tablets, TVs)
- Medical imaging devices
- Automotive displays
Problems Solved
- Addressing display pixel hysteresis
- Ensuring consistent and accurate display of images
Benefits
- Improved display quality
- Enhanced user experience
- More accurate representation of images
Original Abstract Submitted
Devices and methods are provided to overdrive or underdrive a display panel to account for display pixel hysteresis due to several frames of pixel history. An electronic device may include an electronic display and processing circuitry. The electronic display includes a number of display pixels. The processing circuitry may generate image data for the display pixels. The processing circuitry may receive a current frame value of the image data targeted for a first display pixel and, based at least in part on the current frame value and a pixel history of the first display pixel—may indicate a gray level for a number of previous frames—generate a compensated value by which to drive the first pixel to overcome pixel hysteresis to reach the desired luminance at an initial response.
