    摘要: The present invention relates to an output voltage stabilization circuit. Specifically, the present invention relates to an output voltage stabilization circuit of a display device driving circuit, which generates a reference current dependent on a high source voltage using a current source independent of a magnitude of the high source voltage, generates a reference current dependent on a low source voltage using a current source independent of a magnitude of the low source voltage, and then generates a control signal by comparing the magnitudes to each other, whereby the output voltage stabilization circuit may stabilize an output voltage regardless of an order in which the low source voltage and the high source voltage are turned off in a circuit using both the low source voltage and the high source voltage.

    摘要: A liquid crystal display driving circuit and method. A data register block of a controller applies in advance a polarity control signal to data before the data are stored in latches of a data driver, exchanges the data, and then stores the exchanged data in the latches.
