US 2022/0189363 A1 · DISPLAY DEVICE, AND METHOD OF OPERATING A DISPLAY DEVICE

Abstract

A display device includes a display panel and a panel driver. In a case where input image data represents a moving image with respect to a first partial region and represents a still image with respect to a second partial region, the panel driver performs a normal frequency driving operation on the first partial region, and performs a low frequency driving operation on the second partial region. In a standby mode, after the normal frequency driving operation and the low frequency driving operation are performed on the first partial region and the second partial region, respectively, the panel driver sets a portion of the second partial region adjacent to the first partial region as an adjacent region, performs the low frequency driving operation on the first partial region and the second partial region except for the adjacent region, and performs a variable frequency driving operation on the adjacent region.

A display device comprising:

a display panel having a display region;
and
a panel driver configured to drive the display panel based on input image data,
wherein, in a case where the input image data represents a moving image with respect to a first partial region of the display region and represents a still image with respect to a second partial region of the display region, the panel driver performs a normal frequency driving operation on the first partial region, and performs a low frequency driving operation on the second partial region, and
wherein, in a standby mode, after the normal frequency driving operation and the low frequency driving operation are performed on the first partial region and the second partial region, respectively, the panel driver sets a portion of the second partial region adjacent to the first partial region as an adjacent region, performs the low frequency driving operation on the first partial region and the second partial region except for the adjacent region, and performs a variable frequency driving operation on the adjacent region.

performing a normal frequency driving operation on a first partial region of the display region in a case where input image data represents a moving image with respect to the first partial region;
performing a low frequency driving operation on a second partial region of the display region in a case where the input image data represents a still image with respect to the second partial region;
setting a portion of the second partial region adjacent to the first partial region as an adjacent region in a standby mode after the normal frequency driving operation and the low frequency driving operation are performed on the first partial region and the second partial region, respectively;
performing the low frequency driving operation on the first partial region and the second partial region except for the adjacent region in the standby mode;
and
performing a variable frequency driving operation on the adjacent region in the standby mode.
