Liquid crystal display and method of driving the same

A display apparatus includes a panel part, a data driver, and a gate driver. The panel part includes a plurality of gate lines, a plurality of data lines, and a plurality of pixels each of which is connected to one gate line of the gate lines and one data line of the data lines. The data driver receives image data and outputs a data signal to the data lines. The gate driver part is disposed on the panel part and applies gate signals to the gate lines. Periods of clock signals controlling the level of the gate signals are different from that of the gate signals. Thus, power consumption of the display apparatus is substantially effectively reduced.

Display apparatus including a gate driver that has a plurality of stages and method for driving the display apparatus

A display apparatus includes; a data driver integrated in one chip and which outputs data signals; a gate driver which sequentially outputs gate signals, a display panel which includes; a plurality of data lines which receive the data signals, a plurality of gate lines which receive the gate signals, and a plurality of pixels connected to a corresponding gate line and a corresponding data line, a voltage generator which generates a common voltage and a storage voltage and provides them to the display panel, and a voltage compensator which receives the storage voltage fedback from the display panel and generates a compensation signal, wherein the display panel further includes a feedback line which provides the voltage compensator with the storage voltage, and wherein the feedback line is electrically connected to the voltage compensator through the data driver.

Display apparatus including voltage compensator to compensate common voltage

A liquid crystal display (LCD) device includes an LCD panel displaying an image, a light source providing the LCD panel with light, a light source flexible printed circuit board (FPCB), a printed circuit board (PCB), and a receiving container. The PCB is electrically connected to the LCD panel. The PCB is in contact with two ends of the light source FPCB. The receiving container is combined with the light source FPCB and the PCB. The receiving container has a through-hole through which the light source FPCB passes. According to the present invention, the receiving container applies pressure so that both ends of the light source FPCB make contact with the PCB and the light source FPCB is electrically connected to the PCB. The light source FPCB, the receiving container, and the PCB are secured to each other. Therefore, the number of steps required to assembly the LCD device may be reduced.

Liquid crystal display device and method of assembling the liquid crystal display device

A display device and a driving method of the same are provided. The display device includes a display panel having gate lines and data lines. A gate driver is included in each of stages and supplies each of the plurality of gate lines with gate signals using a clock signal and a clock bar signal. Each of the stages includes a gate output terminal through which the gate signal is outputted, a pull-down unit connected to the gate output terminal that pulls down a level of the gate signal using a first gate-off voltage. A holding unit is connected to the gate output terminal and holds the level of the pulled-down gate signal at a level of a second gate-off voltage using the second gate-off voltage, which is higher than the first gate-off voltage.
