Abstract
Disclosed is a display device including a display module, a scaler that outputs image data in a pre-defined format by processing an image signal input through an input source, and a timing controller that controls an operation of the display module based on the image data output from the scaler. The pre-defined format includes an image frame period in which the image data is included and a blank period in which the image data is not included. The scaler outputs a panel on signal for turning-on the display module by using the blank period, and the timing controller turns on the display module based on the panel on signal included in the blank period being identified.
Claims15
A display device, comprising:
- a display module;
- a scaler configured to output image data in a pre-defined format by processing an image signal input through an input source;
- and
- a timing controller configured to control an operation of the display module based on the image data output from the scaler,
- wherein the pre-defined format includes an image frame period in which the image data is included and a blank period in which the image data is not included,
- wherein the scaler is configured to output a panel on signal for turning-on the display module by using the blank period, and output the image data using an image frame period after a blank period included with the panel on signal, and
- wherein the timing controller is configured to turn-on the display module based on the panel on signal included in the blank period being identified, and output the image data to the display module from an image frame period after at least one image frame period from which black image data is output.
A method for controlling a display device comprising a display module, a scaler that outputs image data in a pre-defined format by processing an image signal input through an input source, and a timing controller, the method comprising:
- outputting, by the scaler, a panel on signal for turning-on the display module;
- and
- turning-on, by the timing controller, the display module based on the panel on signal being identified,
- wherein the pre-defined format includes an image frame period in which the image data is included and a blank period in which the image data is not included,
- wherein the scaler outputs the panel on signal using the blank period, and
- wherein the method further comprises:
- outputting, by the scaler, the image data using an image frame period after a blank period included with the panel on signal;
- and
- outputting, by the timing controller, the image data from an image frame period after at least one image frame period from which black image data is output to the display module.
A non-transitory computer-readable medium that stores computer instructions for a display device to perform an operation when executed by a processor of the display device which comprises a display module, a scaler that outputs image data in a pre-defined format by processing an image signal input through an input source, and a timing controller, the operation comprising:
- outputting, by the scaler, a panel on signal for turning-on the display module;
- and
- turning-on, by the timing controller, the display module based on the panel on signal being identified,
- wherein the pre-defined format includes an image frame period in which the image data is included and a blank period in which the image data is not included,
- wherein the scaler outputs the panel on signal using the blank period, and
- wherein the operation further comprises:
- outputting, by the scaler, the image data using an image frame period after a blank period included with the panel on signal;
- and
- outputting, by the timing controller, the image data from an image frame period after at least one image frame period from which black image data is output to the display module.
