摘要:
A driving method for an electrophoretic display having a plurality of first electrodes, a second electrode, and electrophoretic particles positioned in a plurality of pixel areas between the first electrodes and the second electrode, comprises applying an initial driving voltage to the electrophoretic particles in the pixel areas for a predetermined time, applying a first image-displaying voltage having a opposite polarity to that of the initial driving voltage to the electrophoretic particles in a portion of the pixel areas for a predetermined time after applying the initial driving voltage, and applying a first constant gray-displaying voltage having the opposite polarity to that of the initial driving voltage to the electrophoretic particles positioned in a portion of the pixel areas for a predetermined time after applying the first image-displaying voltage.According to the driving method for the electrophoretic display according to an embodiment of the present invention, the images displayed in pixel areas are gradually changed to display smoothly such that display performance of the electrophoretic display may be improved and an incidental image may be prevented.

A drive controller for an electrophoretic display includes a data driver for applying image-altering drive signals to selected ones of a plurality of pixels where the driver includes: a memory unit for storing an alteration progress indicator and a target state indicator. In each of predetermined time spans such as successive display frames, image-altering drive signals are applied and the corresponding progress indicators are updated to reflect the application of the image-altering drive signals in the predetermined time spans. When the progress indicators indicate that the image-altering jobs are finished, the driver stops applying the image-altering drive signals to the respective pixels and instead applies a compensating signal to recover their original optical states. Different pixels can be updated in time-overlapping manner so that the electrophoretic display responds to new image commands in real-time.

A display device having a contact sensing function, and a driving method thereof are disclosed in one embodiment. The driving method of a display device includes reading sense data signals of a current sensing unit row, determining whether the sense data signals are included in a contactable range and converting the sense data signals into preliminary signals that each have a predetermined value based on the determination result, determining whether a sensed area (an X axis sensed area) in an X axis direction exists using the preliminary signals, determining whether the X axis sensed area is effective when the X axis sensed area exists, determining whether a sensed area (a Y axis sensed area) in a Y axis direction exists when the X axis sensed area is effective, determining whether the Y axis sensed area is effective when the Y axis sensed area exists, determining a contact position when the Y axis sensed area is effective, and reading sense data signals of a next sensing unit row when the X axis sensed area or the Y axis sensed area is not effective.

Disclosed are embodiments of an electrophoretic display apparatus and an operating method thereof. According to one or more embodiments, an update voltage compensating for the degradation of an image is applied to a related pixel after a predetermined time interval elapses, when a plurality of images are consecutively displayed on one screen. Thus, the update voltage may be prevented from being applied to the pixel before the image degradation occurs, thereby preventing the pixel from being over-charged.

A three-dimensional image display device includes a three-dimensional image generator and a display panel. The three-dimensional image generator includes a memory part, a control part, and an output buffer part. The memory part has a lookup table storing pixel-shift data corresponding to a plurality of viewpoints and depths. The control part stores image data and depth data in an internal memory, and outputs shifted image data based on the pixel-shift data. The output buffer part outputs three-dimensional image data based on the shifted image data. The display panel displays the three-dimensional image data.
