Abstract
A light emitting display apparatus includes a control driver configured to perform a deterioration prevention function, a scaler configured to transfer a deterioration prevention function activation request signal to the control driver and transfer a deterioration prevention function deactivation request signal to the control driver based on an analysis result of input image data when deterioration prevention function start information is received from the control driver, and a light emitting display panel configured to display images under the control of the control driver.
Claims19
A light emitting display apparatus comprising:
- a control driver configured to perform a deterioration prevention function;
- a scaler configured to transmit a deterioration prevention function activation request signal to the control driver, and transmit a deterioration prevention function deactivation request signal to the control driver based on an analysis result of input image data when deterioration prevention function start information is received from the control driver;
- and
- a light emitting display panel configured to display images under control of the control driver,
- wherein after a preset period elapses since the scaler has transmitted the deterioration prevention function deactivation request signal to the control driver, the scaler transmits another deterioration prevention function activation request signal to the control driver.
An electronic apparatus comprising:
- a display panel configured to display images;
- at least one driver configured to drive the display panel;
- a control driver configured to supply image data to the at least one driver, and activate a deterioration prevention function on the display panel;
- and
- a scaler configured to analyze image data input thereto, determine a change in the image data, and transmit a deterioration prevention function deactivation request signal to the control driver when the change in the input image data is determined to be equal to or greater than a reference value,
- wherein the control driver starts the analyzing of the image data input thereto in response to a deterioration prevention function activation request signal received from the scaler, and
- wherein after a predetermined time period has elapsed since the transmission of the deterioration prevention function deactivation request signal to the control driver, the scaler regenerates and transmits another deterioration prevention function activation request signal to the control driver.
An electronic apparatus comprising:
- a display panel configured to display images;
- at least one driver configured to drive the display panel;
- a control driver configured to supply image data to the at least one driver, and activate a deterioration prevention function on the display panel;
- and
- a scaler configured to analyze image data input thereto, determine a change in the image data, and transmit a deterioration prevention function deactivation request signal to the control driver when the change in the input image data is determined to be equal to or greater than a reference value,
- wherein the reference value is 0.1% of the input image data corresponding to one image.
