Abstract: A driver chip for controlling a high-resolution display panel is presented. The driver chip is not much larger than a conventional driver chip that is currently used for lower resolution display panels. The driver chip applies data signals to the data lines of the display panel and gate control signals to a gate driver that is formed in the peripheral region of the display panel. The gate driver, which may be made of amorphous silicon TFTs, generates gate signals in response to the gate control signals from the driver chip and applies the gate signals to gate lines. Since the driver chip of the invention controls more gate lines and data lines than a conventional chip of about the same size, the driver chip may be easily adapted for display devices having multiple panels. Where multiple panels are used, the panels may be scanned simultaneously or sequentially.

Abstract: A display device includes a display panel and a voltage generating part. The display panel includes a switching element, a main pixel section, a coupling capacitor and a sub pixel section. The main pixel section is electrically connected to the switching element. The coupling capacitor has a first end electrically connected to the switching element. The sub pixel section is electrically connected to a second end of the coupling capacitor. The voltage generating part controls data voltages corresponding to a gray-scale in a range from a low gray-scale to a high gray-scale that corresponds to a saturation voltage of the sub pixel section for displaying an image. The data voltages are applied to the display panel. Therefore, the viewing angle and the luminance are improved.

Abstract: Disclosed are a liquid crystal display device and a method for manufacturing the same, in which wirings connected between pads and an integrated circuit is protected from being corroded. A pixel array is formed on a display region of a substrate. A plurality of pads are formed on a non-display region of the substrate. An integrated circuit is formed on the non-display region of the substrate and connected to the pads to generate a signal for operating the pixel array. Conductive barrier layers separated from each of the pads are formed on peripheral portions of the pads connected to the integrated circuit. The conductive barrier layers have electric potential equivalent to that of each of the pads in accordance with internal connections of the integrated circuit. When bumps of the integrated circuit and the pads are attached to each other, the conductive barrier layers prevent the pads and the wirings connected to the pads from being corroded.
