Description of the invention: [Technical field of the invention] The present invention relates to a driving device for a panel and a drive thereof, and is related to a driving device for a plasma display panel, and \-lt- 〇/ , *, [Prior Art] The light-emitting principle of the conventional plasma display is to excite the visible light by exciting the gas by emitting ultraviolet rays to excite the (4) agent on the partition wall. The gas illuminating process is mainly performed by three eyes, which are electrodes, scanning electrodes, and address electrodes. The sweep (four) pole address ^ generates a wall charge, and the scanning electrode and the sustain electrode continue to emit light by alternating the excitation gas. Μ Form: 1 is the indication of the gray level brightness produced by the conventional plasma display. The ❻ 斋 发光 can be divided into three positions, the sub-replacement week is indicated by two right-hand oblique lines, and the position is assigned. (indicated by the upper left to the lower right line), the maintenance period (from the upper right to the lower left oblique line column) First, the reset period will make the wall charge a comprehensive state update. Then, the address electrodes of the coincident data line and The scanning antennas of each scanning electrode are sequentially determined, whether wall charges are generated in the corresponding sub-pixels (ie, the stomach address of the mouth). The circumference ij is the alternating current of the scanning electrode and the sustaining electrode, so that each time The addressed person in the pixel is illuminated. In order to display the gray level of different brightness, the frame period is divided into multiple sub-fields (subfieki) SFO'SFl, ..., Na (each sub-domain has different time lengths) The sustain period is determined by determining the address state of each sub-pixel in each sub-field 200805234 18275twf.doc/g = ~ SF8 t (ie, determining whether each sub-prima is rendered with a different gray level during the corresponding sub-domain. It can be clearly seen from FIG. 1 that the sustain periods of the subfields SF0 to SF8 are different, and nine subfields 1 are small 2, 4, 8, 16, 32, 64, 128, for example, when a certain sub-pixel is to be displayed. Gray level m, can be determined in sub-field training ~ SF7 Addressing the sub-pixel and emitting light, and in the sub-domain _, the coffee does not address the sub-pixel (and thus does not emit light), so the average brightness of the sub-pixel between the frames is grayscale 127. The illuminating weight value of the sub-pixel is The mathematical method is added as G + 1 + 2 + 4 + 8 + 16 + 32 + 64 + 〇 = 127. If you want to display the gray level 128, you can make the sub-pixel in the sub-domain coffee ~ milk does not emit light in the sub-domain The SF8 hair is presented, that is, its illuminating weight value 〇+ 〇旦Μ日士1+1 +G + G+ 128-128. However, this method will appear in the non-static ^ 守守' will be due to the concentration of human visual center of gravity Dynamic quasi-like phenomenon. When viewing non-static images, for example, when moving from brightness 128 to direct 12:, the pixel does not emit illusion in sub-domain SF〇~(4) sentences. In the case of contours, for non-still images, the effect has a degree of phase. For example, in the face of the face movement, black lines and the like appear on the cheeks. ... Figure ^ is to solve the dynamic contour Display screen map. When dealing with non-static screens, configure the rules in two different gray levels. A and B indicate that the grayscale configuration rule A and the grayscale configuration rule b configuration = frame are issued in ^2. The grayscale configuration rules A and B^ have different sub-tools respectively as an example. To make a pixel display grayscale 32, the grayscale 5ITW 18275twf.doc/g 200805234 configures rule A to cause the subpixel to emit light in subfield SF6 (ie, the illuminating weight value 0 + 0 + 0 + 0 + 0 + 〇 + 32 + 0 + 0 = 32), and the gray-scale configuration rule B enables the sub-pixel to emit light in the sub-fields SF0 to SF5 (ie, the illuminating weight value is 1 + 1 + 2 + 4 + 8 + 16 + 0 + 0) + 0 = 32). In any case, the grayscale configuration rules A and B can cause the sub-pixel to display a grayscale %.

Root = feed, two points Pixel seven (five)) The longer it is, the longer it is between the two lighting times. 8 18275twf.doc/g 200805234 It is redundant, so it will cause the problem of quenching. Because of the plasma. , / / has the function of displaying non-static and static pictures, so + must be the same method, for non-static pictures and static face can have good: there is a kind of [invention], the shoulder does not result. The object of the present invention is to provide an electro-convex display surface, which is not only in the non-static inspection of the plasma display panel, but also in the case of a power-disappearing display, in which the driving surface stops the dynamic pseudo-contour and the extinction point. The problem is that, according to the above and other purposes, the driving device proposed by the present invention comprises a gray-scale configuration unit and a static-disconnected panel-level configuration controller. The gray-scale configuration unit receives the image ^= and gray-gray steps. The configuration rule converts the image data into the first---==豕=same-element to detect the image data θ μ : fi.

When the image data is non-static, the first sub-domain data and the second sub-domain are alternately provided with the image frame timing; The driving device displays the panel. When the image data is a static image, the first sub-domain data and the second sub-domain data are alternately provided along with the wire frame space to drive the plasma display panel. The static picture and the static picture are driven in different ways, so the structure is in the plasma The non-static surface of the display panel prevents the occurrence of dynamic pseudo-contours, and the static picture on the plasma display panel can prevent the problem of quenching points. The above and other objects, features and advantages of the present invention are more apparent. It is to be understood that the preferred embodiments are described below, and are described in detail below with reference to the accompanying drawings.
