Abstract: A display device and a method of operating the same is disclosed. In one aspect, the display device includes a display panel having a plurality of pixels electrically connected to a plurality of data lines and a power supply configured to generate at least one bias voltage. The display device also includes a charge share controller configured to calculate voltage differences between current data voltages and previous data voltages and to generate at least one charge share control signal based on the voltage differences. The display device further includes a data driver configured to selectively perform a charge share operation or a precharge operation based on the charge share control signal. The charge share operation includes electrically connecting at least two of the data lines to each other and the precharge operation includes applying the bias voltage to the data lines.

Abstract: A two-dimensional/three-dimensional switchable display apparatus includes: a display panel; a first substrate disposed on the display panel; a first electrode layer disposed on the first substrate and including a plurality of first electrodes; a second substrate disposed on the first substrate; a second electrode layer disposed on the second substrate and including a plurality of second electrodes; and a liquid crystal layer disposed between the first and second substrates. A plurality of lens units are formed in association with a first position of the liquid crystal layer when a lens forming voltage profile is applied to the first electrodes and a common voltage is applied to the second electrodes. When the common voltage is applied to the first electrodes and the lens forming voltage is applied to the second electrodes, the plurality of lens units are formed in association with a second position spaced apart from the first position.

Abstract: An image processing part includes an edge enhancing part, an artifact detecting part and a compensating part. The edge enhancing part emphasizes an edge portion of an object in input image data. The artifact detecting part detects a corner outlier artifact at an area adjacent to the edge portion of the object. The compensating part compensates the corner outlier artifact. Accordingly, the edge portion of the object may be enhanced and the corner outlier artifact is decreased so that the display quality may be improved.

Abstract: Gamma applied data generating circuit includes motion vector extractor, gamma pattern generator, first gamma applier, second gamma applier, and output converter. Motion vector extractor extracts motion vector of object. Gamma pattern generator generates first gamma pattern corresponding to first motion vector value and second gamma pattern corresponding to second motion vector value from first time point. Value of motion vector is changed from first motion vector value to second motion vector value at first time point. First and second gamma appliers generate first and second data by applying first and second gamma pattern to input data, respectively. Output converter outputs sum of first data times first weight and second data times second weight as gamma applied data. From first time point to second time point, output converter converts first weight from 1 to 0 and converts second weight from 0 to 1.
