Abstract
In a liquid crystal television, segment electrodes of a liquid crystal panel are divided into image segment electrodes and indicator segment electrodes. A liquid crystal display unit includes an image segment driver for receiving a video signal from a television receiver and driving the image segment electrodes, and an indicator segment driver for receiving a tuning voltage from a tuning voltage control unit and driving the indicator segment electrodes. The image and indicator segment drivers are driven by signals having different voltage waveforms.
