[0007] However, the display method of Pixel Chidori causes the same picture to have only A phase, and the next picture only has B phase. Repeating this is the main reason for the flickering of the picture.

Embodiment Construction

[0022] The method of reducing the dynamic false contour of the plasma display proposed by the present invention is mainly to compare the gray value of each input pixel with the gray value of the first 5 pixels. If the gray value of any one of the first 5 pixels is The value and setting method are the same as the current input pixel, then change the setting method of the currently input pixel (A becomes B or B becomes A), we use Figure 4A , Figure 4B , Figure 4C as well as Figure 4D Explain separately. (Comparing 5 pixels is only an example, the present invention is not limited to this)

[0023] Please refer first Figure 4A . Figure 4A It shows the first 6 pixels (pixel) of a plasma display, which are pixel 1 (pixel 1) to pixel 6 (pixel 6). Similarly, we use the well-known AB phase method as the basis, that is, the setting method of pixel 1 (pixel 1) is A, the setting method of pixel 2 (pixel 2) is B, and the setting method of pixel 3 (pixel 3) is A, etc... Such staggered ...

Abstract

The invention proposes a method for reducing dynamic false contours in a PDP, comprising the steps of: 1. determining a grey scale setting method for a pixel; if the grey scale value and grey scale setting method of any one of N pixels before the pixel are identical with those of the pixel, changing the grey scale setting method for the pixel, where N is an integer not less than two; finally, outputting the pixel.

Description

Technical field [0001] The invention relates to a display method of a plasma display, and in particular to a method for reducing dynamic false contours of the plasma display. Background technique [0002] Plasma Display Panel (PDP) uses inert gas electron discharge to generate ultraviolet ray to excite the coated red, green, and blue phosphors to present a picture of various colored light spots. The emergence of PDP has greatly changed the display ecology of medium and large size (about 40-70 inches). With its ultra-thin size and weight, it is much smaller than traditional large-size CRT TVs, and it is digital, high-resolution, and not affected by magnetism. , Wide viewing angle, flat screen, etc., which are in line with the needs of light, thin, short and small multimedia products. [0003] However, when a plasma display displays a dynamic image frame, the contour phenomenon of the gray scale disorder often occurs in the position of the image frame, which is the so-called dynamic...
