Embodiment Construction

[0053] The specific implementation manner of the present invention will be further described in detail below with reference to the drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0054] In practical applications, overdrive technology is generally used to increase the response speed of liquid crystals, thereby improving the response time of liquid crystals.

[0055] Taking TFT-LCD (Thin film transistor-liquid crystal display) as an example, when the gate-source voltage of the TFT is greater than the drain voltage, the source and drain of the TFT are turned on, and the voltage applied to the source is quickly charged to On the storage capacitor CS (CS shortens the charging time) and CLC. When the gate-source voltage of the TFT is lower than the cut-off voltage of the TFT, its source and drain are cut off, and the voltage applied to the source cannot be charged to t...

Abstract

The invention provides a method and a device for determining overdrive voltage as well as a display device, relates to the technical field of liquid crystal display and is used for reducing the workload during determination of overdrive gray scale brightness. The method for determining the overdrive voltage comprises steps as follows: acquiring gray scale brightness of a target frame image; acquiring the setting time of overdrive of to-be-processed frame images and display time of each frame of one image; determining the overdrive gray scale brightness of the to-be-processed frame images according to the gray scale brightness of the target frame image, the setting time of overdrive and the display time; determining the corresponding overdrive voltage according to the overdrive gray scale brightness. The method and the device for determining the overdrive voltage as well as the display device are mainly applied to the technical field of liquid crystal display.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a method, a device and a display device for determining an overdrive voltage. Background technique [0002] With the development of display technology, liquid crystal display has gradually become the mainstream device in display devices due to its advantages of small size, high resolution, thin and light appearance, low energy consumption and radiation. From the working principle of the liquid crystal display, the liquid crystal requires a relatively long response time from being subjected to an applied force to reaching the required rotation angle. [0003] In the prior art, the overdrive voltage is generally obtained through an LCD-Overdrive lookup table method. In this method, first determine the initial potential VPF and the target potential VCF, then set the overdrive voltage VOD, and observe whether the measured response curve is the best curve. If not, the...
