International ClassG09G 5/00AbstractA liquid crystal display (LCD) capable of enhancing display quality includes a voltage generation unit, a clock generation unit, a gate driving unit, and a display unit. The voltage generation unit outputs a gate-on voltage and first and second gate-off voltages that are different from each other. The clock generation unit outputs a first clock signal and a second clock signal whose phase is opposite to the phase of the first clock signal. The first clock signal swings between the gate-on voltage and the first gate-off voltage. The gate driving unit is provided with the first clock signal, the second clock signal, and the second gate-off voltage and outputs a gate signal. The display unit includes a plurality of pixels that are turned on or off in response to the gate signal and that display an image.Field of SearchLiquid crystal display segmentsController automatically senses monitor resolution Including priming means Adjusting display pixel size or pixels per given area (i.e., resolution) Subpixels have different shapes Non-binary weighted Binary weighted Changing of subpixel location over time Having three or more voltage levels Including optical means Spatial processing (e.g., patterns or subpixel configuration) Waveform generator coupled to display elements Controlling the condition of display elements Temporal processing (e.g., pulse width variation over time Physically integral with display elements Field period polarity reversal Display power source DISPLAY DRIVING CONTROL CIRCUITRY Light detection means (e.g., with photodetector) Synchronizing means Regulating means Intensity or color driving control (e.g., gray scale) Having common base or substrate 345/ 84 345/107 | |
