Embodiment Construction

[0013] Please refer to figure 1 and Figure 4 , Figure 4 A flowchart illustrating a method for driving the liquid crystal display 100 according to an embodiment of the present invention. Figure 4 The method is to use figure 1 The liquid crystal display 100 description, the detailed steps are as follows:

[0014] Step 400: start;

[0015] Step 402: When the liquid crystal panel 102 displays a frame according to an image data, compare whether the brightness of the first half-plane of the liquid crystal panel 102 is the same as the brightness of the second half-plane; if not, go to step 404; if yes, go to step 408 ;

[0016] Step 404: When the brightness of the first half-plane of the liquid crystal panel 102 is not equal to the brightness of the second half-plane of the liquid crystal panel 102, adjust the first image data corresponding to the first half-plane of the liquid crystal panel 102 in the image data to generate A new image data;

[0017] Step 406: The liquid c...

Abstract

The invention provides a method for driving a liquid crystal display. The method for driving the liquid crystal display comprises the following steps of: when a picture is displayed according to an image data, comparing the luminance of a first semi-plane and a second semi-plane of a liquid crystal display panel of the liquid crystal display; when the luminance of the first semi-plane is not equal to the luminance of the second semi-plane, adjusting a first image data, corresponding to the first semi-plane, in the image data so as to generate a new image date; and according to the new image data, displaying the next picture by using the liquid crystal display panel, wherein the first semi-panel is a semi-panel, further away from a drive circuit, in the liquid crystal display panel.

Description

technical field [0001] The present invention relates to a method for driving a liquid crystal display, especially a method for using an integrated driving circuit to adjust the initial setting value of the buffer in the integrated driving circuit so that the brightness of the first half plane of the liquid crystal panel is the same as that of the first half plane. The brightness of the second half-plane is the same as the method of driving the LCD. Background technique [0002] The integrated driving circuit applied to small-sized LCD panels includes a timing controller, a source driving circuit, a gate driving circuit, and a DC / DC converter, among which the integrated driving circuit can pass through Modify the initial setting value (initial code) in the register to control the output of the integrated driving circuit. [0003] Please refer to figure 1 and figure 2 , figure 1 To illustrate a schematic diagram of a liquid crystal display 100, figure 2 It is a schemati...
