Driving method for LCD

Abstract

The invention relates to a driving method of a liquid crystal display, which receives a display signal first, wherein the display signal comprises a plurality of image data and each image data includes an objective driving voltage; next, establishes an object function according to the object driving voltage and calculates an objective visual visibility according to the object driving voltage; then, modulates a driving voltage to a best visual display voltage and a voltage reference, upon which an adjusting function is established and an adjusting visual visibility is calculated; finally, adjusts the best visual display voltage and the reference voltage to allow the adjusted visual visibility equal to the objective visual visibility, and the best visual display voltage and the reference voltage adjusted are used for driving the display image data. The driving method has the advantages that visual comfort can be improved, image persistence can be reduced and response time can be shortened.

Description

technical field [0001] The present invention relates to a driving method of a liquid crystal display, in particular to a driving method of a liquid crystal display which can adjust the visual brightness and make the adjusted visual brightness equal to the preset target visual brightness . Background technique [0002] In the era of highly developed multimedia technology, monitors for displaying images have already unconsciously become an indispensable and important part of life. Among them, due to the advantages of high display resolution and thinner size specifications, liquid crystal displays gradually replace traditional video tube displays with the advancement of technology, and are widely used in notebook computers. Meanwhile, with the continuous development of large-sized panels recently, liquid crystal displays are gradually applied to displays of desktop computers or home multimedia devices. [0003] In a display system of a liquid crystal display, usually a displa...

Problems solved by technology

[0015] Those who have ordinary knowledge in the field of picture-driven display-related technologies can understand that there are generally three shortcomings in the above-mentioned processing modes: one is that human beings will feel that the picture image presented by each piece of picture data is more accurate than the predetermined target value. The second is that each picture data is processed with reference to the previous picture data, and it is easy to see the residual image of the previous picture due to the factor of persistence of vision; the third is that for each picture data, the reaction time is usually about A time interval that requires a picture time (such as picture time FT1 and FT3)
