A respective one of a plurality of data lines is connected to a respective column of LCD elements. A column of dummy LCD elements is disposed adjacent an outermost column of the array of LCD elements, and a dummy data line is connected to the dummy LCD elements of the column of dummy LCD elements. Preferably, a respective one of the plurality of data lines extends along a side of the column of LCD elements to which it is connected, between the column of LCD elements to which it is connected and an adjacent column of LCD elements, and the dummy data line extends along a side of the column of dummy LCD elements, between the column of dummy elements and the adjacent outermost column of the array of LCD elements. Data line driving means may be provided for driving a respective one of the plurality of data lines with a respective data signal having a respective polarity, a data signal driving a respective data line having a polarity which is inverted with respect to the polarity of a data signal driving an adjacent column of LCD elements. Dummy data line driving means may be provided for driving the dummy data line with a dummy data signal which has a polarity which is inverted with respect to the polarity of the data signal driving the data line connected to the outermost column of LCD elements. The column of dummy LCD elements may be obscured from a user of the LCD.
A liquid crystal panel driving method and apparatus of cycle inversion system is adapted to stably keep a picture quality independently of a pattern of picture and improves a picture quality. In the apparatus, liquid crystal cells in the liquid crystal panel are divided into a number of polarity blocks. The same polarities of data signals are applied to the liquid crystal cells included in each polarity block, data signals having polarities different from the adjacent polarity blocks to each polarity block. The number of liquid crystal cells included in each of the number of polarity blocks are gradually increased every predetermined number of frame period.
A method of fabricating LCD devices from large array substrates having redundant pixels. Large array substrates without defects can be used to fabricate large LCD device and the redundant pixels can be disabled. Large array substrates with defects can be cut into smaller array substrates and then used to form small LCD devices. The pixels around the cutting lines of the large array substrate are redundant and can be covered or disabled.
The present invention relates to a light emitting device where currents passing through scan lines have the same values. The light emitting device includes data lines, scan lines, pixels, one or more dummy data line and a cross-talk preventing circuit. The data lines are disposed in a first direction, and the scan lines are disposed in a second direction. The pixels are formed in cross areas of the data lines and the scan lines. The dummy data line is disposed in the first direction. The cross-talk preventing circuit provides a compensating current to scan line related to luminescence of the scan lines through the dummy data line so that total sum of current passing through the scan line has a desired value. In the light emitting device, currents passing through scan lines have the same values, and so a cross-talk phenomenon is not occurred to a panel.
A liquid crystal display device includes a plurality of gate lines arranged in a first direction and spaced apart at a constant interval, a plurality of data lines arranged in a second direction perpendicular to the gate lines at a constant interval so as to define pixel regions arranged in a matrix configuration, a plurality of pixel electrodes formed in the respective pixel regions, and a dummy data line formed at one side of the pixel electrodes connected to the last data line.
A method of driving a liquid crystal display device, wherein the liquid crystal display device adopts a previous gate type including a gate line; a data line perpendicularly crossing with the gate line; a dummy gate line adjacent the gate line; a thin film transistor connected to the gate and data lines to serve as a switching element; a liquid crystal capacitor receiving signals from the thin film transistor; and a storage capacitor connected to the liquid crystal capacitor, the method including applying a dummy gate signal to the dummy gate line, wherein the dummy gate signal has substantially the same waveform as a gate signal applied to the gate line.
