A display apparatus includes pixels, gate lines and data lines, a gate driver driving the gate lines, a data driver driving the data lines, and a timing controller controlling the gate and data drivers and applying a resolution control signal to the data driver. The data driver applies a first line data signal to the pixels connected to a first gate line of the gate lines from image data and a second line data signal to a second gate line of the gate lines based on the first line data signal in response to a shift start pulse signal when the resolution control signal indicates an up-scaling mode.

A display apparatus includes a first pixel, a second pixel, a first selector, and a second selector. The first pixel includes first sub-pixels connected to a first gate line and respectively connected to corresponding data lines included in a first data line group and the second pixel includes second sub-pixels connected to a second gate line adjacent to the first gate line and respectively connected to corresponding data lines, one of which is included in a second data line group different from the first data line group. The first selector applies first data signals to one of odd-numbered data lines, and the second selector applies second data signals having a different polarity from the second data signals to one of even-numbered data lines.

A display device includes a data request unit in a frame rate controller, and requires and transmits necessary data for the frame data buffer receiving and storing the image data of an entire pixel area and the rest of the frame rate controllers. In a case of a motion picture that is moved among a plurality of display areas, the image data corresponding to a plurality of regions is transmitted from the frame data buffer or a plurality of frame rate controllers, and in a case of the motion picture that is moved between neighboring pixel areas, the image data of the neighboring pixel area is transmitted from the frame data buffer or the neighboring frame rate controller for processing. Accordingly, a fast-moving motion picture may be realized without the need for an additional memory.

A timing controller is adapted to support a display apparatus that operates with image data having a configuration of M-bits per word and an average serial data flow rate corresponding to CK1 image words per second where CK1 is a first clock frequency and M is a whole number. The timing controller includes a data mapper that converts supplied image data from the M-bits per word times CK1 words per second configuration into a P-bits per word times CK2 words per second configuration so that the mapped data matches the configuration of an external memory. The timing controller also includes a data remapper that performs the inverse conversion. In one embodiment, M is 24 while P is 32.
摘要:
In a liquid crystal display, a timing controller compares a current pixel data signal corresponding to a currently driven gate line with a previous pixel data signal corresponding to a previously driven gate line to output control signals, and selectively outputs an output pixel data signal corresponding to the currently driven gate line. A data driver drives the data lines in response to the control signals and the output pixel data signal. Thus, the size of the pixel data signal provided from the timing controller to the data driver is reduced, thereby reducing power consumption and EMI thereof.
