  • Patent number: 8599188
    Abstract: In a data driver, an inverter inverts a first data signal from a first group of data signals. A converter includes first and second converting circuits. The first converting circuit converts a second data signal included from second group of data signals into a first gamma voltage. The second converting circuit has a circuit configuration inverted with respect to the first converting circuit. The second converting circuit converts the inverted first data signal into a second gamma voltage. An output buffer stores the first and second gamma voltage outputs from the converter and then outputs them. Thus, although gamma voltage is interfered from the coupling between a signal line and a gamma voltage line, a user can have normal images regardless of s the gamma voltage variation. The present invention relates to charge-trapping memories in the application of display panels.

    Abstract: A driving circuit includes digital/current converting (DCC) circuits one for each data line. The DCC circuit charges a capacitor with a reference current according to a supplied signal from a shift register. The DCC circuit stores a current value of the reference current and outputs the current value to a data line via a switching element turned on by a digital image data signal of a single line supplied from a line latch. The output value of each DCC circuit is reset one after another in every select scan period in which an OFF signal is sent to all the data lines. Thus, the reset of the output value and the output of the image data signal can be successively carried out within one frame period, so the data applied to the pixel circuit with the DCC circuits one for each data line.
