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

This abstract first appeared for US patent application 17869218 titled 'DISPLAY DEVICE AND METHOD OF DRIVING THE SAME

Simplified Explanation

The patent application describes a display device that adjusts the power voltage applied to a display panel based on the maximum grayscale value of the input image data. This is achieved by a driving controller that generates a voltage control signal and a power voltage generator that senses the power current and controls the voltage level.

  • The display device adjusts the power voltage applied to the display panel based on the maximum grayscale value of the input image data.
  • A driving controller generates a voltage control signal to adjust the first power voltage in each frame.
  • A power voltage generator senses the power current and generates a second power voltage based on the voltage control signal.
  • The voltage level of the first power voltage is controlled based on the second power voltage and the current level of the power current.

Potential Applications

  • This technology can be applied in various display devices such as televisions, computer monitors, and mobile devices.
  • It can improve the image quality and power efficiency of these display devices.

Problems Solved

  • The technology solves the problem of inconsistent power voltage levels applied to the display panel, which can affect image quality.
  • It addresses the issue of power inefficiency by dynamically adjusting the power voltage based on the input image data.

Benefits

  • Improved image quality due to the adjustment of power voltage based on the maximum grayscale value.
  • Enhanced power efficiency by dynamically controlling the voltage level based on the power current.
  • The technology can be implemented in existing display devices without significant modifications.


Original Abstract Submitted

A display device includes a display panel which displays an image based on input image data, a driving controller which generates a voltage control signal for adjusting a first power voltage applied to the display panel in an (N+M)-th frame based on a maximum grayscale value of the input image data of an N-th frame, where N is a positive integer, and M is a positive integer, and a power voltage generator which senses a power current applied to the display panel in the (N+M)-th frame, generates a second power voltage based on the voltage control signal, and controls a voltage level of the first power voltage based on the second power voltage and a current level of the power current.
