Abstract: A driving device of a display apparatus and a display apparatus including the same are provided to generate stable gray scale voltages by improving the delay of gray scale voltages even when a voltage level of the gray voltages is swung between first and second voltage levels. A driving device of a display apparatus includes first and second gray scale voltage generators(240a,240b), and a digital to analog converter. The first gray scale voltage generator distributes a gamma reference voltage, which is supplied from outside, to plural gray scale voltages through a first resistance string. The second gray scale voltage generator distributes the gamma reference voltage into plural auxiliary gray scale voltages through a second resistance string and applies the distributed voltages to an output stage of the gray scale voltage. The digital to analog converter converts digital data signals, which are supplied from outside, into analog data signals based on the gray scale voltages and outputs the converted signals.

Abstract: A display device and a data driving unit for the same are provided to use a data clock signal corresponding to a resolution by enabling a data driver to self-discriminate the resolution. A display device includes a shift register(220), a latch unit(230), a DAC(240), an output buffer(250) and a resolution determining unit(260). The shift register shifts a horizontal start signal in response to a data clock signal and outputs a sampling signal. The latch unit latches the data signal in response to the sampling signal, and outputs the latched data signal in response to a load signal. The DAC converts the data signal from the latch unit to a corresponding analog data signal. The output buffer buffers the analog data signal. The resolution determining unit counts the horizontal start signals to determine a resolution.

Abstract: A driver for a display device is provided to prevent an LCD device from being damaged by an excessive source voltage by lowering an operation voltage of the LCD device, when an operation voltage for a source driver is close to a bonding temperature. A driver for a display device includes a current source(210), a current mirror circuit(220), a thermistor(225), a reference resistor(226), and an output terminal(203). The current mirror circuit delivers the current from the current source to first and second nodes. The thermistor is connected between the first node and a ground voltage and has a resistance varied according to a peripheral temperature. The reference resistor is connected between the second node and the ground voltage and has a predetermined reference resistance. The output terminal outputs the voltage of the second node to the outside.

Abstract: A data driver and a display device having the same are provided to prevent an erroneous operation of the display device due to a small timing margin by generating an updating control signal by synchronizing with a second data clock signal. A shift register(210) shifts a horizontal start signal by synchronizing with a data clock signal from an external controller to generate a sampling signal. A first latch latches and outputs a load signal by synchronizing the data clock signal. A second latch latches and outputs an output signal from the first latch by synchronizing with the data clock signal. A logic operation unit combines the outputs from the first and second latches to output an updating control signal. A data latch unit(240) latches the data signal in response to a sampling signal and outputs and updates the latched data signal in response to the updating control signal. A DAC(Digital to Analog Converter)(250) converts the data signal from the data latch unit to an analog signal and outputs the analog signal.
