Liquid crystal device and method for driving same

Abstract

A liquid crystal display device which implements a pause-drive technique, wherein flickering is effectively suppressed while also suppressing increases in power consumption. When a frame, to which an image signal (DAT) is inputted from the outside without outputting a request signal (RO) that makes a request to the outside for the input of the image signal (DAT), is defined as a first input frame, an inversion drive control unit (10) specifies that the first input frame is a refresh frame defined as a first refresh frame, also specifies that the inversion drive technique of the first input frame is the column inversion drive technique, specifies that the three frames following the first refresh frame are pause frames, specifies that the frame following the final pause frame is a refresh frame defined as a second refresh frame, and specifies that the inversion drive technique of the second refresh frame is the dot inversion drive technique.

Description

technical field [0001] The present invention relates to a liquid crystal display device, and more particularly, to a liquid crystal display device performing idle driving (low frequency driving) and a driving method thereof. Background technique [0002] Conventionally, an active matrix liquid crystal display device including a TFT (Thin Film Transistor) as a switching element is known. This liquid crystal display device includes a liquid crystal panel including two insulating substrates facing each other. On one substrate of the liquid crystal panel, gate bus lines (scanning signal lines) and source bus lines (video signal lines) are provided in a grid pattern, and TFTs are provided near intersections of the gate bus lines and source bus lines. The TFT includes: a gate electrode connected to a gate bus line; a source electrode connected to a source bus line; and a drain electrode. The drain electrode of each TFT is connected to one of a plurality of pixel electrodes arran...

AI Technical Summary

Problems solved by technology

[0006] In general, if the polarity inversion pattern in the inversion driving method adopted is complex, flickering is less likely to occur, but power consumption increases

On the other hand, if the polarity inversion pattern in the inversion driving method adopted is simple, the power consumption will be reduced, but flickering will easily occur
