Abstract: A timing controller for an LCD panel includes a signal receiver, a data reader, a signal receiver, a logic control unit, and a data conversion unit. The signal receiver receives transmitted signals, and the data reader acquires data from the signal receiver. The logic control unit receives the data acquired by the data reader to generate pixel data, and the data conversion unit receives the pixel data and converts them into serial signals. The timing controller converts the pixel data and the control commands into serial signals, and then they are transmitted in serial to each of the source driver chips.

Abstract: An image format conversion system includes a horizontal filter to receive an image input signal with a frequency of a first clock signal in order to perform a filtering operation to thereby produce a horizontal filtering image signal; a first FIFO to temporarily store the horizontal filtering image signal; a 2D image interpolator to perform a deinterlacing, a vertical interpolation and a horizontal interpolation operations on the horizontal filtering image signal to further produce a scaled progressive image signal; a second FIFO connected to the 2D image interpolator to temporarily store the scaled progressive image signal; an interpolation clock controller to receive a second clock signal and produce multiple enable signals in order to enable the horizontal filter and the 2D image interpolator, wherein the second clock signal has a frequency independent of the frequency of the first clock signal.

Abstract: A system for integrating de-interlace and overdrive operations includes a de-interlace device, a first frame scaling controller, a second frame scaling controller and an overdrive device. The de-interlace device performs a de-interlace operation on plural fields to thereby obtain plural frames. The first frame scaling controller receives a first frame among the plural frames and performs a vertical and horizontal scaling operation on the first frame to thereby produce a first display frame. The second frame scaling controller receives a second frame among the plural frames and performs a vertical and horizontal scaling operation on the second frame to thereby produce a second display frame. The overdrive device produces a driving voltage based on a difference between a pixel of the second display frame and a pixel of the first display frame corresponding to the pixel of the second display frame.

Abstract: A circuit structure and method for enhancing motion picture quality are provided. This circuit comprises a frame memory and two dual-port buffers. The memory structure can read the previous frame data and store the present frame data at the same time. Therefore, it can provide a simpler access control and structure of memory than the prior art. The circuit compresses the data by a nonlinear quantization method, which can reduce the size of the frame memory. The circuit uses alternate reading/writing and interpolation by using the adjacent pixels to further reduce the size of the frame memory.

Abstract: A system integration chip for display and memory control applied to a card recognition module is provided. The card recognition module includes a module casing, a memory card, an oscillator, a storage, and a display. The system integration chip is disposed in the module casing for recognizing a data stored in the memory card and storing the data in the storage, and the data is converted into a signal by the oscillator and then displayed by the display.
