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

This abstract first appeared for US patent application 18213898 titled 'DRIVING CONTROLLER, DISPLAY DEVICE, AND METHOD OF DRIVING DISPLAY DEVICE

Simplified Explanation

The abstract describes a display device with a degradation controller that compensates for pixel degradation by adjusting driving voltages and power consumption.

  • The degradation controller calculates a driving voltage increase amount based on the degradation of the maximum degradation pixel.
  • The global current controller compensates for power increase by calculating a scale factor based on the driving voltage increase amount.
  • The driving voltage provider increases the driving voltage to the pixels according to the calculated driving voltage increase amount.
  • The data compensator generates output image data by scaling the scale factor to grayscale values of input image data.
  • The data driver provides data voltages to the pixels based on the output image data.

Potential Applications

This technology could be applied in various display devices such as smartphones, tablets, monitors, and TVs to improve image quality and extend the lifespan of the display.

Problems Solved

This technology addresses the issue of pixel degradation in display devices, ensuring consistent image quality over time and reducing power consumption.

Benefits

The benefits of this technology include improved image quality, extended display lifespan, reduced power consumption, and overall enhanced user experience.

Potential Commercial Applications

Potential commercial applications of this technology include consumer electronics, digital signage, medical displays, and automotive displays.

Possible Prior Art

One possible prior art could be display devices with basic degradation compensation techniques, but not as advanced and integrated as the one described in this patent application.

Unanswered Questions

1. How does the degradation controller determine the maximum degradation pixel among the pixels? 2. What specific types of display technologies can benefit the most from this technology?


Original Abstract Submitted

A display device includes a display unit which includes a plurality of pixels, a degradation controller which includes a voltage compensator configured to calculate a driving voltage increase amount based on a degradation amount of a maximum degradation pixel among the pixels and a global current controller configured to calculate calculates a first scale factor for compensating a power increase amount according to the driving voltage increase amount, a driving voltage provider which is configured to increase a driving voltage provided to the pixels based on the driving voltage increase amount, a data compensator which is configured to generate output image data by scaling the first scale factor to grayscale values of input image data, and a data driver which is configured to provide data voltages to the pixels based on the output image data.
