摘要： An amplifier and a driving device of a display device using the same reduce a size of the whole circuit by reducing the number of input transistors. An input unit(810) is connected between a first power source supplying the first voltage and a second power source supplying the second voltage. An input unit receives the first input signal and the second input signal and is controlled according to the first and second input signals. A bias unit(820) receives a bias voltage for operating the input unit and includes a first node and a second node controlled by the input unit. A first output transistor is turned on and off according to the signal applied to the first node. A second output transistor is turned on and off according to the signal applied to the second node. An output unit(830) applies an output voltage to a pixel by using the first output transistor and the second output transistor.

摘要： PURPOSE: A driving device and a display device including the same are provided for multiple driving chips to display images in the same operating mode by delivering a final operating mode to the operating chip operated with a slave. CONSTITUTION: A master driving chip(510) and slave driving chips(520,530) have signal terminals(SCL, SY) and a share terminal(FD). A signal terminal(SCL) is used as the interface of control data. A signal terminal(SY) is used as the interface of a mode detecting signal(SD). A master driving chip is connected to a memory part(900). The master driving chip reads control data(DA) from the memory part through a signal terminal(SCL). The slave driving chip reads the control data from the memory part through the signal terminal. The master driving chip and the slave driving chip determine whether to operate in a normal mode or an abnormal mode. The master driving chip determines a final operation mode.

摘要： A liquid crystal display device, a driving device thereof, a digital analog converter, and an output voltage amplification unit reduce a cost and a size for implementing the liquid crystal device by decreasing the number of switches included in the data drivers. A plurality of scan lines transmit a plurality of scanning signals. A plurality of data lines transmit a plurality of data signals. A plurality of pixels are defined by the plurality of scan lines and the plurality of data lines. A reference gradation voltage generator generates a plurality of reference gradation voltages. A data driver generates the plurality of data signals by combining 2k voltages which is decided as one of first and second gradation voltages and corresponds to a bit value of m-k bits among image signals of m bit applied from the outside based on the plurality of reference gradation voltages. The data driver applies generated data signals to the plurality of pixels. The data driver includes first to third decoders(30322-30326) and the digital analog converter.
