摘要： An active matrix type display apparatus includes a display panel, a horizontal display driver and a controller. The horizontal display driver includes m (m is an integer larger than 1) horizontal driving sections to drive the display panel based on m display data sets in response to an output clock signal, respectively. The controller generates the output clock signal from an input clock signal, and carries out sampling of input data to produce display data for a horizontal line of the display panel. Also, the controller sequentially stores the display data and outputs the stored display data to the m horizontal driving sections in units of display data sets in response to the output clock signal, respectively.

摘要： A driving device for an LCD panel is provided which is capable of preventing the occurrence of light or dark shade among pixels during a non-writing period. All the pixels of the LCD panel are driven by each source driver to receive various signals from a control section and a reference voltage from a reference voltage generating section and each gate driver to receive a gate control signal from the control section using an AC voltage driving method. For a specified period of time after the ending of a writing period, a display data signal, an AC-DC voltage inverting control signal, a latch signal, and a reference voltage are fed to each source driver and an intermediate voltage of an AC driving voltage or a specified voltage is fed to data lines.

摘要： A method of driving a display panel is provided which is capable of restoring normal operation to a timing controller in which an abnormality in display control has occurred. When a signal detecting section of one timing controller detects an abnormality that no signal is input or that a supply of a clock signal is stopped, the detected result is transferred from a two-way communicating section of the one timing controller to a two-way communicating section of the other timing controller. The other timing controller having received the detected result transfers a normal image signal and/or clock signal from the two-way communicating section of the other timing controller to the two-way communicating section of the one timing controller. The one timing controller exerts display control of a liquid crystal display panel according to the transferred image signal and/or clock signal.

摘要： A data outputting method is provided which is capable of reducing a memory capacity of a LUT (Look-Up Table). Compressed data obtained by dropping low-order bits making up gray-level data is stored in a manner in which the compressed data can be accessed by high-order bits to be input to the LUT. High-order bits making up an address output from an address supplying unit are supplied to the LUT and low-order bits are supplied to a computing unit. The LUT outputs compressed gray-level data corresponding to the high-order bits and compressed gray-level data corresponding to data of (high-order bit+1). The computing unit outputs each of expanded gray-level data obtained by dividing data obtained by interpolation among one expanded gray-level data, another expanded gray-level data and, third expanded data for every high-order bit based on one compressed data, other compressed data, and lower-bits.

摘要： A timing controller is provided which is capable of achieving normal image display at a time of reverse scanning in upward and downward directions and right and left directions. In an image display device having a plurality of scanning line driving ICs (Integrated Circuits), a valid line counting section counts a count of valid driving lines based on a DE (Data Enable) signal and DCK (Dot Clock) signal. A cascade signal counting section counts up a total count of outputs from a count of VCK (Vertical Clock) signals including a VSP (Vertical Start Pulse) 2 output signal up to a VSP1 cascade outputting signal VSP1. A calculating section calculates an excessive output of a scanning line driving IC from a difference between the count of valid driving lines and the total count of outputs. A VSP generating section generates and outputs a VSP2 signal at a time shifted from a reference VSP generating time by time being equivalent to the excessive output calculated by the calculating section thus enabling reverse scanning.
