Abstract

The invention provides a display control device of a liquid crystal screen. The display control device comprises a frequency obtaining unit and a signal output unit, wherein the frequency obtaining unit is used for obtaining a corresponding initial signal frequency according to received image information of an image display signal; and the signal output unit is used for outputting a corresponding initial signal to a display driving device of a liquid crystal screen according to the initial signal frequency, so that the liquid crystal screen has a corresponding scanning frequency. According to another aspect of the invention, a display control method of the liquid crystal screen is provided. With the adoption of the technical scheme of the invention, the liquid crystal screen can be controlled to fresh an image in a corresponding scanning frequency according to the information of an image signal; poor image display effect or influence to the eyesight of a user caused by the simplification of an image fresh frequency is avoided; and an optimal display effect is achieved.

Description

technical field

[0001] The present invention relates to the technical field of liquid crystal screen driving, in particular, to a scanning frequency control device, a display control device and a scanning frequency control method of a liquid crystal screen, a display control method, and a display device. Background technique

[0002] Traditional LCD panels are generally divided into three mainstream panels: 60 Hz, 120 Hz, and 240 Hz. Most common TV signal sources use a single image refresh rate of 60 Hz or 120 Hz. For shutter-type 3D LCD screens, most of the 3D images A single image refresh rate control of 120 Hz or 240 Hz is adopted, and there is no application scheme for multiple frequency conversion, which is a single fixed refresh rate. For example, for shutter-type 3D images, 240 Hz images are better, while for ordinary signals, 60 Hz or 120 Hz images are better. If the frequency is forced to be lowered, the picture may freeze. If the frequency is forced to be increased...
