Abstract
A display apparatus including: a self-luminous display panel; an image processor which processes an image signal and displays an image on the display panel based on the processed image signal; and a controller which performs a reset operation to remove remaining electrons from the panel by discharging the panel at a preset interval while the image is displayed, and selectively performs a first reset operation and a second reset operation based on image information quantity of frames of the image displayed on the panel, wherein the first reset operation is performed to discharge the entire panel and the second reset operation is performed to sequentially discharge divided areas, into which the panel is divided, at the preset interval.
Claims21
A display apparatus comprising:
- a self-luminous display panel;
- an image processor configured to process an image signal and display an image on the display panel based on the processed image signal;
- and
- a controller configured to perform a reset operation which removes remaining electrons from the display panel by discharging the display panel at a preset interval while the image is displayed, and selectively perform a first reset operation and a second reset operation based on image information quantity of frames of the image displayed on the display panel, wherein the first reset operation is performed to discharge the entire display panel at the preset interval, and the second reset operation is performed to sequentially discharge divided areas of the display panel, at the preset interval.
A control method of a display apparatus comprising a self-luminous display panel, the control method comprising:
- processing an image signal and displaying an image on the display panel based on the processed image signal;
- performing a reset operation for removing remaining electrons from the display panel by discharging the display panel at a preset interval while the image is displayed;
- wherein the performing the reset operation comprises selectively performing one of a first reset operation and a second reset operation based on image information quantity of frames of the image displayed on the display panel, wherein the first reset operation discharges the entire display panel at the preset interval, and the second reset operation sequentially discharges divided areas, into which the display panel is divided, at the preset interval.
A display apparatus comprising:
- a self-luminous display panel;
- an image processor configured to process an image signal and display an image on the display panel based on the processed image signal;
- and
- a controller configured to analyze image information quantity of a frame of the image displayed in real-time, discharge the entire display panel at a predetermined interval to reset remaining electrons of the display panel if it is determined that the image information quantity of the frame is larger than a preset level, and sequentially discharge a plurality of display areas of the display panel at the predetermined interval, and does not discharge the entire display panel if it is determined that the image information quantity is smaller than the preset level.
A control method of a display apparatus comprising a self-luminous display panel, the control method comprising:
- processing a received image signal and displaying the received image on the display panel based on the processed image signal;
- determining an average picture level (APL) of image frames of the received image;
- and
- if the APL is higher than a preset level, performing a reset operation to discharge the entire display panel, and if the APL is lower than the preset level, performing the reset operation to discharge the entire display panel at an interval of a predetermined number of frames.
