Display driving circuit and operating method thereof

A display driving circuit comprising:

• a first amplifier configured to drive a first data line of a display panel based on first pixel data;
• a second amplifier configured to drive a second data line of the display panel based on second pixel data;
• and
• a controller configured to receive the first pixel data and the second pixel data during a first horizontal driving period, and
• when a first data difference between the first pixel data and the second pixel data being less than or equal to a horizontal threshold value N, N being a positive integer, enable a first one of the first amplifier and the second amplifier and disable a second one of the first amplifier and the second amplifier during a second horizontal driving period such that, during the second horizontal driving period, the first one of the first amplifier and the second amplifier is configured to,
• drive the first data line and the second data line based on the second pixel data during a first period within the second horizontal driving period, and
• drive the first data line based on the first pixel data during a second period within the second horizontal driving period, the first horizontal driving period and the second horizontal driving period being single consecutive horizontal driving periods of the display panel,
• wherein the first data line is connected to a first sub-pixel of a first pixel and the second data line is connected to a second sub-pixel of a second pixel,
• wherein the first sub-pixel and the second sub-pixel have identical color, and
• wherein the first pixel is adjacent to the second pixel.

A display device comprising:

• a first pixel comprising a first red sub-pixel, a first green sub-pixel, a first blue sub-pixel, and a second green sub-pixel;
• a second pixel comprising a second red sub-pixel, a third green sub-pixel, a second blue sub-pixel, and a fourth green sub-pixel;
• a first amplifier configured to drive a first data line of a display panel based on first pixel data;
• a second amplifier configured to drive a second data line of the display panel based on second pixel data;
• a third amplifier configured to drive a third data line of the display panel based on third pixel data;
• a fourth amplifier configured to drive a fourth data line of the display panel based on fourth pixel data;
• a fifth amplifier configured to drive a fifth data line of the display panel based on fifth pixel data;
• a sixth amplifier configured to drive a sixth data line of the display panel based on sixth pixel data;
• a seventh amplifier configured to drive a seventh data line of the display panel based on seventh pixel data;
• a eighth amplifier configured to drive a eighth data line of the display panel based on eighth pixel data;
• wherein, when a data difference between the first pixel data and the fifth pixel data is less than or equal to a first threshold value, the fifth amplifier is disabled, and the first amplifier drives the first red sub-pixel and the second red sub-pixel;
• wherein, when a data difference between the second pixel data and the sixth pixel data is less than or equal to a second threshold value, the sixth amplifier is disabled, and the second amplifier drives the first red sub-pixel and the second red sub-pixel;
• wherein, when a data difference between the third pixel data and the seventh pixel data is less than or equal to a third threshold value, the seventh amplifier is disabled, and the third amplifier drives the first red sub-pixel and the second red sub-pixel;
• wherein, when a data difference between the fourth pixel data and the eighth pixel data is less than or equal to a fourth threshold value, the eighth amplifier is disabled, and the fourth amplifier drives the first red sub-pixel and the second red sub-pixel;
• and
• wherein the first pixel and the second pixel is adjacent to each other.
