DISPLAY DEVICE AND DRIVING METHOD FOR THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18199372 titled 'DISPLAY DEVICE AND DRIVING METHOD FOR THE SAME

Simplified Explanation

The patent application describes a display device that includes pixel circuits with light emitting elements and grayscales. It also includes a dummy pixel circuit with a dummy light emitting element and a dummy driving transistor.

  • The display device has a sensing unit that inputs test data signals to the dummy pixel circuit to generate compensation information for degradation of the light emitting element and driving transistor based on the output signal.
  • A timing controller accumulates and stores the compensation information and generates compensated data by compensating for the data input from the outside.

Potential applications of this technology:

  • This display device can be used in various electronic devices such as smartphones, tablets, televisions, and computer monitors.
  • It can also be used in automotive displays, wearable devices, and virtual reality headsets.

Problems solved by this technology:

  • The display device compensates for the degradation of the light emitting elements and driving transistors, ensuring consistent and accurate display performance over time.
  • It addresses the issue of pixel degradation that can lead to uneven brightness or color shifts in displays.

Benefits of this technology:

  • The display device provides improved image quality and color accuracy by compensating for degradation.
  • It extends the lifespan of the display by mitigating the effects of degradation.
  • It enhances the user experience by maintaining consistent display performance over time.


Original Abstract Submitted

Provided is a display device comprising pixel circuits included in the display area, the pixel circuits including light emitting elements with grayscales corresponding to data input from the outside, a dummy pixel circuit included in the non-display area, the dummy pixel circuit including a dummy light emitting element and a dummy driving transistor, a sensing unit for inputting to the dummy pixel circuit, a test data signal for sensing an output signal corresponding to predetermined test data for each predetermined time, and then performing an operation of generating compensation information for compensating for degradation according to a driving time of at least one of the light emitting element and the driving transistor based on the output signal output from the dummy pixel circuit, and a timing controller for accumulating and storing the compensation information, and generating compensated data by compensating for the data input from the outside.
