发明名称 Data driving circuit for liquid crystal display
摘要 A data driving circuit for a liquid crystal display wherein it has a simplified circuit configuration so that it may be easily integrated to a liquid crystal display panel. In the data driving circuit, a data input device receives n-bit video data. A clock generator generates 2n different clock signals. A digital-to-analog converter array generates a sampling pulse having a different phase in accordance with a magnitude of the video data from the data input means using the 2n clock signals and sampling an input ramp signal in response to the sampling pulse to apply the sampled ramp signal to each of data lines in a liquid crystal panel. Accordingly, a circuit configuration of the digital-to-analog converter is simplified, so that the data driving circuit can be easily integrated onto a narrow area thereof.
