A circuit generates a reference voltage in inverse proportion to the variation in temperature to control the gate-on voltage for a gate line of a liquid crystal display so that the liquid crystal display may display an image without distortion.

Temperature compensating arrangement for liquid crystal display

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.

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.

A display that has rush current reduction during power-on is provided. A display panel that displays an image includes a gate line and a data line. A voltage generator receives a supply voltage and outputs a gate-on voltage and a gate-off voltage to first and second output nodes, respectively. The voltage generator includes a pull-up capacitor that is charged for a first time period of a power-off period and is discharged for a second time period of the power-off period to increase a voltage level of the second output node, the first and second time periods being consecutive periods of the power-off period. A gate driver selectively applies a gate-on voltage or a gate-off voltage to the gate lines, and a data driver applies a data voltage to the data line.
