A display apparatus includes a display panel, a first covering part, an upper frame and a lower frame. The first covering part is disposed on the display panel. The upper frame is disposed under the first covering part and includes a first combining portion. The lower frame is combined with the upper frame through the first combining portion, and overlaps a peripheral portion of the display panel.

Display apparatus

A liquid crystal display device includes; gate lines disposed on a display region, data lines disposed on the display region, wherein the data lines intersect with, and are insulated from, the gate lines, a gate driver which drives the gate lines, a plurality of data drivers which generate a data voltage from an input power source voltage and supply the data voltage to the data lines, and a power source voltage supplying unit which supplies different power source voltages to each of the data drivers according to a distance of each data driver from the gate driver.

Liquid crystal display device and method of driving the same

A panel assembly includes a display panel and a panel driving apparatus. The display panel includes a data line and a gate line extended in a direction that crosses the data line. The panel driving apparatus includes a first gate driving circuit that outputs a first gate signal to the gate line, and a second gate driving circuit disposed in an area that corresponds to an inverter and that outputs a second gate signal to the gate line, the second gate signal being different from the first gate signal.

Panel assembly and display apparatus having the same

A display apparatus and a driving method thereof, in which the display apparatus includes a temperature sensor detecting a temperature, a first memory, a timing controller that receives an (n&#x2212;1)th image signal and an nth image signal of consecutive frames, corrects the nth image signal and outputs the nth image signal, wherein the timing controller generates a clock signal whose phase varies according to the detected temperature, writes the nth image signal in the first memory in synchronization with the clock signal, reads the (n&#x2212;1)th image signal from the first memory, and compares the nth image signal and the (n&#x2212;1)th image signal with each other to then correct the nth image signal based on the comparison result, a data driver that provides an image-data voltage corresponding to the corrected signal of the nth image signal, and a liquid crystal panel that displays an image corresponding to the image-data voltage.

A liquid crystal display device has a flexible circuit board which can prevent the disconnections of output side conductive layer patterns formed at the border portion of the solder resist layer. A flexible base film has a liquid crystal panel engaging portion, engaged with a liquid crystal panel on one side thereof. A driving IC is formed at the central portion of the base film to apply driving signals to driving devices of the liquid crystal panel. A first conductive layer patterns are extended on the base film from the driving IC to the liquid crystal panel engaging portion to electrically connect the driving IC to the liquid crystal panel. A solder resin layer exposes the first conductive layer patterns formed on the liquid crystal panel engaging portion and covers the first conductive layer patterns of the periphery of the driving IC. A reinforcing member prevents the first conductive layer patterns from disconnecting due to the bending fatigue of the border portion of the liquid crystal panel engaging portion and the solder resin layer.

The present invention applies different common voltages to common electrodes corresponding to both end points of gate lines and data lines. At this time, the highest common voltage is applied to a common electrode point far away from both a data driver and a gate driver, the second highest common voltage is applied to a common electrode point close to the data driver and far away from the gate driver, the third highest common voltage is applied to a common electrode point far away from the data driver and close to the gate driver, and the lowest common voltage is applied to a common electrode close to both of the data driver and the gate driver.
