Abstract: A liquid crystal display system including a signal processing device uses interpolation to generate an intermediate image frame using previous image frame data and present image frame data. The system converts data of the intermediate image frame into transposed image data that is to be used to drive a liquid crystal display panel and display a corresponding image. The transposed image data and the present image data are subjected to a prespecified DCC process (dynamic capacitance compensation process) to thereby generate respective first and second compensation image data. Since the first compensation image data is generated based on the transposed image data and the transposition is configured to prevent over-compensation by the DCC process, over-compensation by the dynamic capacitance compensation process can be reduced or prevented.

Abstract: A display apparatus set includes a signal receiver/transmitter, a scaler, a driving circuit, and a first display panel. The signal receiver/transmitter receives an image signal from an external device, outputs a portion of the image signal as a first image signal, and outputs a remaining portion of the image signal as a second image signal. The scaler receives the first image signal and converts a size and a resolution of an image included in the first image signal to output the converted first image signal. The driving circuit receives the converted first image signal and converts the converted first image signal to output a data signal. The first display panel receives the data signal to display an image. The second image signal is similarly treated and displayed on a second display panel.

A compensation data of a current frame is generated based on to which one of the first, second and boundary areas grayscale data of previous and current frames belongs.

Abstract: A display apparatus includes a display panel, a plurality of gate lines driving circuit parts, a plurality of data lines driving circuit parts and a timing control part. The display panel includes a plurality of gate lines and a plurality of data lines. The gate lines driving circuit parts output gate signals to the gate lines. The data lines driving circuit parts output data signals to the data lines. The timing control part applies a dummy gate signal to at least one dummy gate line, controls a latch sequence of image data and an output sequence of the gate lines driving circuit parts in a reverse sequence, in response to an inverted-mounting mode selection signal for displaying an inverted mount image to the display panel. Because signal lines can be shortened, heat generated by the display apparatus may be decreased and image quality of the display apparatus may be improved.

The data driver converts the first and second compensation frames to a left-eye data voltage and a right-eye data voltage, respectively, and converts the first and second intermediate image frames to a predetermined black data voltage.

Abstract: An apparatus and method for driving a liquid crystal display apparatus include a receiver for receiving input image data, a data processor for processing output image data output from the receiver, and a memory and a transmitter connected to the data processor. The data processor selects a portion of polarities from the output image data and generates a plurality of polarities of the same number as the portion of the polarities to generate polarity data for one frame. Thus, polarities of pairs of pixels corresponding to inversion units are sequentially inverted, so that arbitrary polarity inversion can be individually performed on the pixels. Therefore, preventing cross line defects that are caused from variation in charging voltages in a conventional two-dot inversion driving scheme that is performed in units of two adjacent pixel rows is possible. Further, reducing flicker caused by polarity inversion in units of one frame is also possible.
