[0047] schematic structure

[0048] figure 1 The figure shows a schematic structure of a liquid crystal display device 1 according to an embodiment of the present invention. The liquid crystal display device 1 includes a liquid crystal display panel 10 , a backlight 20 arranged on the back of the liquid crystal display panel 10 , and a driving circuit 30 that drives the liquid crystal display panel 10 . The liquid crystal display panel 10 has, for example, a pixel array section 13 in which a plurality of subpixels 11R, 11G, and 11B are arranged in a matrix. In the present embodiment, for example, sub-pixels 11R, 11G, and 11B adjacent to each other form one pixel 12 . Here, below, the sub-pixels 11R, 11G, and 11B are collectively referred to as sub-pixels 11 as appropriate. The drive circuit 30 has, for example, a video signal processing circuit 31 , a timing generation circuit 32 , a signal line drive circuit 33 , a scan line drive circuit 34 , and a common connection line dr...

Abstract

The invention discloses a liquid crystal display apparatus and a method of driving liquid crystal display apparatus. A liquid crystal display apparatus includes a pixel array section having a plurality of scanning lines disposed in rows, a plurality of signal lines disposed in columns, a plurality of pixel circuits, a plurality of liquid crystal elements, and a plurality of common connection lines, and a drive circuit section having a scanning line drive circuit, a signal line drive circuit, and a common connection line drive circuit. The drive circuit section drives each of the pixel circuits so that a holding period in each frame period has a period during which a voltage of one liquid crystal element falls and a period during which the voltage rises.

Description

technical field [0001] The present invention relates to an active matrix liquid crystal display device and a method for driving the liquid crystal display device. Background technique [0002] In recent years, liquid crystal display devices for video display that drive display elements (liquid crystal elements) by using liquid crystals have been widely used. In such a liquid crystal display device, by changing the alignment of liquid crystal molecules in a liquid crystal layer sealed between substrates made of glass or the like, light from a light source is passed or modulated to perform display. [0003] As display images move toward higher definition and higher luminance, problems that have not been given much attention have become apparent. Among these problems, an important one is display flicker and increase in power consumption. One reason for the deterioration of flicker is that the influence of the current leaked from the pixel circuit increases due to the smaller ...
