Embodiment Construction

[0025] see Figure 6, is a schematic diagram of the circuit structure of the present invention for actively driving the liquid crystal display panel. The actively driven liquid crystal display panel 10 works in a normally black mode, that is, when no image signal is applied to the actively driven liquid crystal display panel 10 , its display screen is in a dark state. The actively driven liquid crystal display panel 10 includes: m (m is a positive integer) rows of first scanning lines 11 parallel to each other, and m (m is a positive integer) rows of second scanning lines 11 spaced from and arranged in parallel with the first scanning lines 11 Lines 12, n (n is a positive integer) columns parallel to each other and the first signal lines 21 that are insulated and intersected with m rows of first scanning lines 11, n (n is a positive integer) columns are spaced from and parallel to the first signal lines 21 The second signal lines 22 are arranged. The active matrix liquid cry...

Abstract

The present invention relates to an actively driven liquid crystal display panel, which includes a plurality of first scanning lines, a plurality of second scanning lines, a plurality of first signal lines, a plurality of second signal lines, a plurality of scanning interconnection lines, a plurality of A first thin film transistor, a plurality of second thin film transistors, and a plurality of pixel electrodes, wherein each first scanning line is electrically connected to a second scanning line through a scanning interconnection line, and makes the connection with the second scanning line The corresponding second thin film transistors are sequentially turned on at gate turn-on timing, and the gate turn-on timing of the second thin film transistor lags behind the gate turn-on timing of the corresponding first thin film transistor. The second signal line is connected to the second thin film transistor When the gate of the transistor is turned on, a black voltage is input to restore the liquid crystal display panel to a state where no image signal is applied. The invention also relates to a driving method for actively driving a liquid crystal display panel. Compared with the prior art, the invention can make the liquid crystal display picture clear.

Description

【Technical field】 [0001] The invention relates to an actively driven liquid crystal display panel, in particular to an actively driven liquid crystal display panel capable of displaying images clearly. The invention also relates to a driving method using the actively driven liquid crystal display panel. 【Background technique】 [0002] Due to the advantages of lightness, thinness, and low power consumption, liquid crystal displays are widely used in modern information equipment such as televisions, notebooks, computers, mobile phones, and personal digital assistants. At present, the application of liquid crystal display in the TV market is becoming more and more important. However, the liquid crystal material itself has a large viscosity coefficient. The response time of ordinary thin film transistor liquid crystal display (Thin Film Transistor Liquid Crystal Display, TFT-LCD) Up to tens of milliseconds (ms), in order to faithfully present the image, the pixel imaging mode mu...
