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

This abstract first appeared for US patent application 18096795 titled 'DISPLAY DEVICE AND METHOD OF DRIVING THE SAME

Simplified Explanation

The patent application describes a display device that adjusts the brightness of images based on whether they are still or moving.

  • The device has a first gain provider that controls the brightness during the display of still images.
  • It also has a second gain provider that controls the brightness during the display of moving images that include still areas.
  • A grayscale converter applies the appropriate gain value to the input image to generate the output image.
  • The first gain provider gradually increases the gain value to a maximum based on the load of the still image.
  • The increase in gain value occurs from the time when the display changes from moving to still image until a certain point.
  • After reaching the maximum gain value, the first gain value starts to decrease.


Original Abstract Submitted

A display device includes a first gain provider which controls a first gain value during a first display period in which a still image is displayed, a second gain provider which controls a second gain value during a second display period in which a moving image including a still area is displayed, and a grayscale converter which applies the first gain value or the second gain value to an input image and generates an output image. The first gain provider linearly or exponentially increases the first gain value to a maximum gain value based on a load of the still image from a first time point when the second display period changes to the first display period to a second time point at which the first gain value starts to decrease from the maximum gain value.
