Liquid crystal display device and control driver for a liquid crystal display device |
摘要 |
A control driver for a liquid crystal display panel includes: an operation circuit, an LUT (Look-up Table), and a linear interpolation D/A converter. The operation circuit performs a certain operation on input image data to generate operation data, and outputs higher order bit data and lower order bit data of the operation data. The LUT includes a V-T (Voltage-Transmittance) characteristic of the liquid crystal display panel, and outputs first output data and second output data as display data based on the higher order bit data and the V-T characteristic. The linear interpolation D/A converter performs an linear interpolation operation and D/A conversion to generate output voltage supplied to the liquid crystal display panel in response to the first output data, the second output data and the lower order bit data.
