摘要: A liquid crystal display (LCD) apparatus and method for automatically sensing and compensating a delay time of a gate signal fed to the LCD display panel. The LCD panel includes a signal converter for generating a power clock signal, a delay controller for generating a delay control signal corresponding to the delay value of the gate signal by comparing the power clock signal with a signal derived from the data lines, and a pixel voltage signal generator for supplying a pixel voltage signal to the data lines of the LCD panel in response to the delay control signal.

摘要: A method and apparatus for driving the data in a liquid crystal display (LCD) panel are presented. The method and apparatus prevent or reduce defects at the boundary between pixel blocks when the pixel blocks are sequentially driven on a block-by-block basis. The method includes applying data signals to a first data block, precharging a second data block that is adjacent to the first data block to a predetermined precharge voltage, and applying data signals to the second data block. The precharging prevents a large voltage difference at the boundary, thereby reducing defects.
