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,
- wherein the exposed display region is moved in a direction opposite to a moving direction of the screen, and
- wherein a location and size of the input image displayed on the exposed display region are fixed while the screen is reciprocated in at least one of vertical and horizontal directions on 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,
- wherein the exposed display region is moved in a direction opposite to a moving direction of the screen, and
- wherein a location and size of the input image displayed on the exposed display region are fixed while the screen is reciprocated in at least one of vertical and horizontal directions on 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,
- wherein a location and size of the input image displayed on the exposed display region are fixed while the screen is reciprocated in at least one of vertical and horizontal directions on the screen.
