Abstract:
A display panel including a first capacitor and a second capacitor is disclosed. The first and second capacitors boost a second driving voltage from a driving chip and apply the boosted second driving voltage to the driving chip. The driving chip receives the boosted second driving voltage and outputs a first driving voltage to drive the display panel. Thus, the display panel does not require any additional capacitor for boosting the second driving voltage, thereby reducing a thickness and a manufacturing cost of the display panel.
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 gate lines, data lines, storage electrode lines and pixels. Each pixel includes a switching element connected to a gate line and a data line, a liquid crystal capacitor connected to the switching element and a common voltage, and a storage capacitor connected to the switching element and a storage electrode line. Signal generating circuits of the display generate storage signals based on gate signals in such a way that the storage signal applied to each pixel has a changed voltage level immediately after the completion of the charging of the data voltage into the liquid crystal capacitor and the storage capacitor. This enables the pixel electrode to reach the target voltage in a single frame, reduces the power consumption of the display, and improves its response time, reliability and durability.

Abstract:
A TFT substrate includes data lines, scan lines, pixels and a shift register. The data lines are extended along a first direction. The scan lines are extended along a second direction that is substantially perpendicular to the first direction. Each of the pixels is defined by a selected data line and a selected scan line. The shift register has stages electrically coupled with each other. An output terminal of a (4K−3)-th stage is electrically connected to a (4K−3)-th scan line, an output terminal of a (4K−2)-th stage is electrically connected to a (4K−1)-th scan line, an output terminal of a (4K−1)-th stage is electrically connected to a (4K−2)-th scan line, and a 4K-th stage is electrically connected to a 4K-th scan line, wherein ‘K’ represents a natural number. Therefore, a 1-line inversion may be accomplished by using a common voltage having a 4H time period to reduce power consumption of a display device.
