Abstract
A rollable display including a flexible display panel having a screen that is separated into an exposed display region and a non-exposed display region. The screen of the flexible display panel is moved using a screen driver, and a moving direction of the exposed display region is controlled to be opposite to a moving direction of the screen, to distribute the stress of pixels, without changing an absolute location of the exposed display region, and to defer degradation of the pixels.
Claims20
A rollable display comprising:
- a flexible display panel;
- a data driver configured to supply a data signal of an input image to the flexible display panel;
- a timing controller configured to transmit data of the input image to the data driver and control an operation timing of the data driver;
- and
- a screen driver configured to move a screen of the flexible display panel,
- wherein the screen of the flexible display panel is separated into an exposed display region and a non-exposed display region,
- wherein the input image is displayed on the exposed display region, and
- wherein the exposed display region is moved in a direction opposite to a moving direction of the screen.
A rollable display comprising:
- a flexible display panel;
- a data driver configured to supply a data signal of an input image to data lines of the flexible display panel;
- a gate driver configured to sequentially supply gate signals to gate lines of the flexible display panel to sequentially scan a screen of the flexible display panel one line by one line;
- a timing controller configured to transmit data of the input image to the data driver and control operation timings of the data driver and the gate driver;
- and
- a screen driver configured to move the screen of the flexible display panel,
- wherein the screen of the flexible display panel is separated into an exposed display region and a non-exposed display region,
- wherein the input image is displayed on the exposed display region, and
- wherein the exposed display region is moved in a direction opposite to a moving direction of the screen.
A driving method of a rollable display having a flexible display panel capable of being rolled by a driving force of a screen driver, the method comprising:
- separating a screen of the flexible display panel into an exposed display region and a non-exposed display region;
- displaying an input image on the exposed display region;
- moving the screen of the flexible display panel using the screen driver;
- and
- controlling a moving direction of the exposed display region to be opposite to a moving direction of the screen.
