DATA COMPENSATOR, DISPLAY DEVICE, AND METHOD OF DRIVING DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18451371 titled 'DATA COMPENSATOR, DISPLAY DEVICE, AND METHOD OF DRIVING DISPLAY DEVICE

Simplified Explanation

The patent application describes a display device that includes a display panel with pixels, a current sensor, a data compensator, a timing controller, and a data driver.

  • The display panel has pixels that can display images.
  • The current sensor measures the current flowing through the pixels.
  • The data compensator calculates a target current for each position of an image frame based on the input image data, current deviation, and current contribution ratio.
  • The timing controller generates output image data by adjusting the grayscale values of the input image data using a scale factor.
  • The data driver provides a data signal to the pixels based on the output image data.

Potential applications of this technology:

  • This display device can be used in various electronic devices such as televisions, computer monitors, smartphones, and tablets.
  • It can enhance the image quality and accuracy of color reproduction in displays.

Problems solved by this technology:

  • The data compensator helps to compensate for any deviations in the current flowing through the pixels, ensuring accurate color reproduction.
  • The timing controller adjusts the grayscale values of the input image data, improving the overall image quality.

Benefits of this technology:

  • The display device provides improved image quality and color accuracy.
  • It enhances the viewing experience for users by delivering more accurate and vibrant images.
  • The technology can be implemented in various electronic devices, making it versatile and applicable in different industries.


Original Abstract Submitted

A display device includes a display panel including a plurality of pixels, a current sensor that senses a sensing current that flows through the pixels, and a data compensator. The data compensator calculates a target current from an image frame of input image data using a current deviation for each position of the image frame and a current contribution ratio for each color of the image frame, and that generates a scale factor by comparing the target current and the sensing current. The display device further includes a timing controller that generates output image data by scaling grayscale values of the input image data using the scale factor; and a data driver that provides a data signal corresponding to the output image data to the pixels.
