A driving method for driving a display apparatus is provided. The driving method includes: configuring a plurality of driving voltages corresponding to a plurality of gray scales, where the gray scales include a first gray scale and a second gray scale smaller than the first gray scale, and a first driving voltage corresponding to the first gray scale is lower than a second driving voltage corresponding to the second gray scale; and controlling the display apparatus to display a gray scale merely up to the second gray scale. In this way, the driving method hence reduces the response time of the display apparatus, which may be an LCD display panel.

Driving method and driving apparatus for displaying apparatus

A pixel array structure includes scan lines, data lines, first pixels, and second pixels. The scan lines and the data lines are intersected. The first and the second pixels are staggered. Each first pixel includes a first switching element, a first pixel electrode and a second pixel electrode electrically connected to the first switching element. Each second pixel includes a second switching element, a third pixel electrode and a fourth pixel electrode electrically connected to the second switching element. The first and the second switching elements electrically connect corresponding scan lines and data lines. A pattern of the first pixel electrode is symmetrical to a pattern of the fourth pixel electrode with respect to an extending direction of the scan lines. A pattern of the second pixel electrode is symmetrical to a pattern of the third pixel electrode with respect to the extending direction of the scan lines.

Pixel array structure

A multi-domain vertical alignment liquid crystal display device includes a data line, a first gate line, a second gate line, a first sub-pixel unit, and a second sub-pixel unit. The first sub-pixel unit includes a first switch, a first liquid-crystal capacitor and a first storage capacitor. The first switch functions to control writing the data signal of the data line into the first liquid-crystal and storage capacitors based on the first gate signal of the first gate line. The second sub-pixel unit includes a second switch, a second liquid-crystal capacitor, an auxiliary switch, a second storage capacitor and a third storage capacitor. The second and auxiliary switches are employed to control writing the data signal into the second liquid-crystal capacitor, the second storage capacitor and the third storage capacitor based on the first gate signal and the second gate signal of the second gate line respectively.

Liquid crystal display device

A touch display panel includes a first substrate, a second substrate, a third substrate, a liquid crystal layer disposed between the second and the third substrates, a pixel array disposed between the liquid crystal layer and the third substrate, an opposite electrode, color filter patterns, a first sensing electrode, and a second sensing electrode. The first, the second, and the third substrates are disposed in parallel. The color filter patterns and the opposite electrode that are disposed between the liquid crystal layer and the second substrate are respectively disposed on opposite sides of the second substrate. Some color filter patterns are piled to form touch points. The first sensing electrode on the first substrate faces the second substrate. The second sensing electrode covers the touch points and some color filter patterns. A height of the touch points is less than a gap between the first and the second substrates.
