摘要:
A liquid crystal display (LCD) and a method of driving the LCD are provided. The LCD includes a display panel; and a timing controller providing a first data signal to the display panel during a first frame period, a second data signal to the display panel during a second frame period and a blank signal to the display panel during a blank period between the first and second frame periods, wherein the voltage of the blank signal varies among a plurality of levels between the voltage of the first data signal and the voltage of the second data signal.

A display device includes first, second, and third gate lines. The display device further includes a first data line and a second data line neighboring the first data line. The display device further includes first, second, and third pixel electrodes connected to the first, second, and third gate lines, respectively, and further includes a fourth pixel electrode connected to the second gate line. The fourth pixel electrode is disposed between the first and third electrodes and neighbors each of the first, second, and third pixel electrodes. The first, second, and third pixel electrodes are connected to the first data line. The display device further comprises a gate driver for applying copies of a gate-on voltage to the gate lines, the gate-on voltage including a first voltage in a first horizontal period, a second voltage in a second horizontal period, and a third voltage in a third horizontal period.

A display apparatus includes pixels connected to gate lines and data lines crossing the gate lines, a data driver which drives the data lines, a gate driver which drives the gate lines, a timing controller which controls the data driver and the gate driver in response to an image signal and a control signal and outputs a first kickback signal and a second kickback signal, and a voltage generator which outputs a first gate-on voltage and a second gate-on voltage in response to the first and second kickback signals to drive the gate lines. The gate driver drives a first group of gate lines in response to the first gate-on voltage and drives a second group of the gate lines in response to the second gate-on voltage.
摘要:
In a method of driving a display panel, a gate signal is outputted to the display panel based on a first control signal. A gamma-corrected analog voltage is generated. A pre-charge compensating analog voltage is generated. A data voltage waveform is generated to include the generated gamma-corrected analog voltage and the generated pre-charge compensating analog voltage during one horizontal period of the display panel. The display panel has a pixel structure in which a data line is alternately connected to first and second subpixel columns adjacent to each other. The pre-charge compensating voltage has a level different from that of the gamma-corrected analog voltage where the latter represents a grayscale level represented by a received digital data signal. According to the method, display defects due to a difference of pre-charging levels used during plural horizontal periods may be decreased so that display quality of the display panel may be improved.
