ELECTROLUMINESCENT DISPLAY DEVICE AND METHOD OF COMPENSATING FOR LUMINANCE IN THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 17895544 titled 'ELECTROLUMINESCENT DISPLAY DEVICE AND METHOD OF COMPENSATING FOR LUMINANCE IN THE SAME

Simplified Explanation

An electroluminescent display device has been developed to compensate for luminance distortion caused by leakage currents through a common conduction layer of pixels. The device includes a display panel, a storage circuit, a luminance compensation circuit, and a data driver.

  • The display panel consists of pixels.
  • The storage circuit stores information on a leakage curve, which indicates the luminance change value of a target pixel based on the input pixel value of a neighboring pixel.
  • The luminance compensation circuit receives input pixel values and generates compensated pixel values by compensating for lateral leakage based on the leakage curve.
  • The lateral leakage is caused by leakage currents through a common conduction layer of the pixels.
  • The data driver drives the pixels based on the compensated pixel values.

Potential applications of this technology:

  • High-quality display panels for electronic devices such as smartphones, tablets, and televisions.
  • Medical imaging devices that require accurate and precise display of images.
  • Automotive displays for navigation systems, entertainment systems, and driver assistance features.

Problems solved by this technology:

  • Luminance distortion caused by leakage currents through a common conduction layer is compensated for, resulting in a more accurate and faithful representation of the input image.
  • The storage circuit and luminance compensation circuit work together to ensure that the exact or close luminance of the input image is realized.

Benefits of this technology:

  • Improved image quality with reduced luminance distortion.
  • Accurate representation of the input image, resulting in a more immersive visual experience.
  • Enhanced performance of display panels in various electronic devices.


Original Abstract Submitted

An electroluminescent display device includes a display panel including pixels, a storage circuit, a luminance compensation circuit and a data driver. The storage circuit stores information on a leakage curve indicating a luminance change value of a target pixel according to a change of an input pixel value of a neighboring pixel, the plurality of pixels including the target pixel and the neighboring pixel. The luminance compensation circuit receives input pixel values corresponding to the pixels and generates compensated pixel values respectively corresponding to the pixels by compensating for lateral leakage based on the leakage curve, where the lateral leakage is caused by leakage currents through a common conduction layer of the pixels. The data driver drives the pixels based on the compensated pixel values. The exact (or close) luminance of the input image is realized by compensating for the luminance distortion.
