An in-plane switching (IPS) liquid crystal display device (100) includes pixel units each having a storage capacitor. The storage capacitor is formed by a common electrode (112), a drain electrode (103), and a counter electrode (110). The common electrode is electrically coupled with the counter electrode. The counter electrode substantially covers the drain electrode, for shielding unexpected coupling effects on the drain electrode due to data signals on a data line (101) driving other pixels of the liquid crystal display device.

A driving method for an active matrix liquid crystal display panel includes the following steps. First, a frame period is divided into a display period (t1) and a black insertion period (tr). A gray-scale voltage is generated according to a desired corresponding light transmittance of each pixel of the liquid crystal display panel; and during the display period, the gray-scale voltage is supplied to a corresponding pixel electrode of the liquid crystal display panel. Then during the black insertion period, a restoring voltage Vh is supplied to the pixel electrode, so that the pixel is returned to an initial black state. Accordingly, the quality of motion pictures of the liquid crystal display panel is good.

A hybrid latch flip-flop is applied to an LCD. The hybrid latch flip-flop includes a negative pulse generation unit, a latch flip-flop, and a buffer unit. The latch flip-flop includes a sampling unit and a hold unit. One feature of the present invention is that fewer transistors are employed in the hybrid latch flip-flop, which gives rise to low power consumption. Another feature of the present invention is that, by employing the negative pulse generation unit of a double edge trigger type, the data processing capacity of the hybrid latch flip-flop is doubled without changing the clock frequency.
摘要:
An LTPS (low temperature poly-silicon) display panel includes a display area and a pair of driving circuit areas. The display area is fabricated by cutting from a display substrate. The driving circuit areas are fabricated by cutting from an insulated substrate having a poly-silicon film thereon. The driving circuit areas are electrically connected with the display area. This approach reduces the impediment to uniformity that is caused by various different processes, and thus improves the yield rate and reduces production costs.
