LIQUID-CRYSTAL DISPLAY DEVICE AND DRIVE METHOD THEREOF

摘要

Provided are a liquid crystal display device and a drive method thereof, capable of promptly making an afterimage, which is visually recognized during pause drive, visually unrecognizable while suppressing power consumption. When updated image data is transmitted, a first refresh is performed by used of this image data, and a refresh pauses based on Ref_int just in the next two-frame period. Then, the second and third refreshes are consecutively performed, and a refresh pause is repeated until the next updated image data is transmitted. In this case, since a refresh can be performed three times in a short period after reception of the updated image data, it is possible to make liquid crystal molecules oriented in a direction corresponding to an applied voltage in a short time and make an afterimage visually unrecognizable.

主权项

1. A liquid crystal display device which performs pause drive at a predetermined refresh rate, the device comprising:
a display portion including a plurality of pixel formation portions; a drive portion for driving the display portion; and a display control portion for controlling the drive portion based on data received from the outside, wherein, when image data included in the data is updated, the display control portion performs a refresh once by use of the updated image data, and then makes a refresh pause just in a pause period that is decided in accordance with a refresh rate of the image data, and after the end of the pause period, the display control portion performs a refresh at least once or more by use of the same image data as the updated image data.
