Embodiment Construction

[0027] In order to make the description of the implementation of the present invention more clear, the following first image field and second image field are respectively taken as an example of an odd image field and an even image field, and the first polarity and the second polarity are respectively positive and negative values example.

[0028] Figure 3A , Figure 3B Each is a schematic diagram of a driving method for a liquid crystal display panel according to a preferred embodiment of the present invention. This method is applicable to the situation that when the scan line data of odd-numbered fields (or even-numbered fields) is driven by line pairs, the number of scan-line data is equal to the number of scan lines of the liquid crystal display panel.

[0029] Please refer to Figure 3A , the right diagram "Scanning line data of TV signal (T)" and the middle diagram "Scanning line data of TV signal (Z)" are essentially the same picture, except that the label of the for...

Abstract

The related drive method for a LCD panel to display menu with both the first and second image fields comprises: sending the scanning line data to the LCD panel by line pairs, and matching the line reversal of the panel for display. Thereby, this invention can add resolution without extra memory or complex algorithm.

Description

technical field [0001] The invention relates to a driving method of a liquid crystal display panel, and in particular relates to a driving method of a liquid crystal display panel for displaying television signals. Background technique [0002] Most TV signals use interlacing, that is, each frame of the TV signal is composed of an odd field and an even field, and the scanning of one frame The lines are interleaved between the scan lines of another field. [0003] figure 1 A schematic diagram of an interlaced television signal is shown. Please refer to figure 1 For example, taking the NTSC TV system as an example, there are 525 scanning lines in one picture, but after deducting the scanning lines used for the flyback, the effective scanning lines that really contain image data are 484, respectively 1, 2, 3, ..., 482, 483 and 484 marked. Moreover, a frame is composed of an odd-numbered field and an even-numbered field, wherein the odd-numbered field includes scan lines ma...
