Description

等离子显示面板的驱动装置及其驱动方法 Other driving device and driving method of the plasma display panel

技术领域 FIELD

本发明有关于一种面板的驱动装置及其驱动方法,且特别有关于一种等离子显示面板的驱动装置及其驱动方法。 A driving device and a driving method of the present invention relates to a panel, and more particularly to a driving device and a panel driving method of a plasma display on.

背景技术 Background technique

现有的等离子显示器的发光原理为通过电极施加电压,使气体发出紫外线激发隔离壁上的萤光剂,而放出人眼可辨识的可见光。 Light-emitting principle of a conventional plasma display, a voltage is applied through the electrode, the gas emits ultraviolet excitation fluorescent agents partition wall, visible to the human eye and emit discernable. 气体发光过程主要由三种电极所控制,分别为维持电极、扫描电极、定址电极。 Gas emission process is mainly controlled by three kinds of electrodes, sustain electrodes, respectively, scan electrodes, address electrode. 扫描电极与定址电极产生壁电荷, 而再由扫描电极与维持电极以交流的形式激发气体而持续发光。 Scan electrodes and the address electrode to generate wall charges, and then scan electrode and the sustain electrode in the form of AC excitation gas continues to emit light.

图1为现有的等离子显示器产生灰阶亮度的示意图。 FIG 1 is a diagram of a conventional plasma display luminance grayscale generation. 等离子显示器发光可分为三个周期,分别为重置周期(以左上至右下之斜直线列表示)、定址周期(以左上至右下之一斜直线表示)、维持周期(以右上至左下之斜直线列表示)。 Emitting a plasma display can be divided into three periods, respectively, the reset period (upper left to lower right represents a straight row of diagonal), addressing period (expressed upper left to lower right diagonal one straight line), the sustain period (upper right to lower left in the oblique line represents the column). 首先, 重置周期将壁电荷做一全面性的状态更新。 First, the reset period will make the wall charge state of a comprehensive update. 接着,连接至数据线的各定址电极与各扫描电极于定址周期依序决定是否于对应的次像素(sub pixel)中产生壁电荷(即所谓定址)。 Subsequently, each of the address electrode and the data line connected to the respective scan electrodes to sequentially addressing period to decide whether the corresponding sub-pixel (sub pixel) wall charges generated (i.e., a so-called addressing). 维持周期则是扫描电极与维持电极施加交流电压,使各次像素中被定址者得以发光。 Sustain period is the scanning electrode and the sustain electrode AC voltage is applied, each sub-pixel is addressed by light. 为了显示不同亮度的灰阶, 一般来说将帧(frame)期间分割为多个子域(subfield) SF0、 SF1、…、SF8 (每个子域具有不同时间长的维持周期), 然后借助分别决定每个次像素于各子域SF0〜SF8中的定址状态(即决定是否于对应子域期间发光),而使每个次像素呈现不同的灰阶。 In order to display gray levels of brightness, generally divided period (Frame) frame into a plurality of sub-domains (subfield) SF0, SF1, ..., SF8 (each subfield having a different length of time the sustain period), then the decision means, respectively, each of subpixel addressed to each sub-field SF0~SF8 state (i.e. determines whether corresponding child domains during emission), each of the sub-pixels of different gray-scale rendering. 由图1可明显看出各子域SF0〜SF8的维持周期有所差异,相当于分别给予九个子域l、 1、 2、 4、 8、 16、 32、 64、 128的发光权重值。 As is apparent from Figure 1 each of the sub-field sustain period SF0~SF8 vary, nine were given the equivalent of subdomains l, 1, 2, 4, 8, 16, 32, 64, 128 of the light emitting weight values.

例如当欲使某一次像素显示灰阶127,则可于子域SF1〜SF7中定址该次像素而发光,并且于子域SF0、 SF8中不要定址该次像素(因而不发光),因此该次像素在一帧期间的平均亮度即为灰阶127。 For example, when a first sub-pixel displays gray purports to 127, the sub-pixel can be addressed to emit light in the sub-field SF1~SF7, and in the sub-field SF0, SF8 not addressed in the sub-pixels (and thus do not emit light), so that the secondary pixel average luminance of one frame period is the 127 grayscale. 该次像素的发光权重值以数学方式加总为0 + 1+2 + 4+8 + 16 + 32 + 64+0 = 127。 The emission times of the weight values ​​of the pixels is mathematically summed 0 + 1 + 2 + 4 + 8 + 16 + 32 + 64 + 0 = 127. 若欲显示灰阶128,则可使该次像素于子域SF0〜SF7不发光而于子域SF8发光来呈现,也即其发光权重值0 + 0 + 0 + 0 + 0+ 0 + 0 + 0 + 128 = 128。 Ruoyu display grayscale 128, will enable the sub-pixels do not emit light in the sub-field SF0~SF7 presented to the light emitting sub-field SF8, i.e. the luminous weight value 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 128 = 128. 但此方法在处理非静态影像时,会由于人类视觉重心的集中会出现动态拟似轮廓现象。 However, this method in dealing with non-static image, will occur due to the concentration of human visual center of gravity of the dynamic false contour phenomenon. 当观赏非静态影像时,例如当从亮度128移至亮度127时,此次像素于子域SF0〜SF8均不发光的错觉。 When a non-static image viewing, for example, when luminance brightness 128 move 127, the pixels in the sub-field emission SF0~SF8 not illusion. 在其他亮度也会出现动态拟似轮廓的情形,对于非静态影像的显示具有相当程度的影响。 The case of dynamic false contour will occur in other brightness for non-static display images have a considerable extent. 举例来说,在显示人脸移动的画面,会使得脸颊上出现黑线等瑕疵。 For example, the face of the display moving pictures, so that the black line will appear on the cheeks and other defects.

图2为解决动态拟似轮廓的显示画面图。 FIG 2 is a solution dynamic pseudo contour display screen of FIG. 在处理非静态画面时,以两种不同灰阶配置规则A、 B来表示,在图2中显示使用灰阶配置规则A与灰阶配置规则B 配置的帧。 When dealing with non-static images, gray scale in two different configuration rules A, B is represented using the frame gradation display configuration rule configuration rules A and B grayscale configuration in FIG. 灰阶配置规则A、 B于同一亮度分别具有不同的子域分配。 Grayscale configuration rules A, B each having a different brightness in the same subfield allocation. 举例来说, 当欲使某一次像素显示灰阶32,则灰阶配置规则A可使该次像素于子域SF6中发光(即发光权重值0 + 0 + 0 + 0 + 0 + 0 + 32 + 0 + 0 = 32),而灰阶配置规则B则可使该次像素于子域SF0〜SF5中发光(即发光权重值1 + 1 + 2+4 + 8 + 16 + 0 + 0 + 0 =32)。 For example, when a first sub-pixel displays gray purports 32, the gray scale configuration rule enables the sub-pixel A to the sub-field SF6 emission (i.e. emission weighting value 0 + 0 + 0 + 0 + 0 + 0 + 32 + 0 + 0 = 32), the gray scale configuration rule will enable the B sub-pixel emission (i.e. emission weight value of 1 + 1 + 2 + 4 + 8 + 16 + 0 + 0 + 0 in the sub-field SF0~SF5 = 32). 无论如何,灰阶配置规则A、 B均可以使该次像素显示出灰阶32。 In any case, the gray scale configuration rules A, B can cause the gray scale of the sub-pixel 32 exhibits.

此显示帧使用AB phase (相)演算法,以空间与时间将帧以灰阶配置规则A 及灰阶配置规则B以多重交错方式配置,而达到视觉重心平均分布的效果。 This display frame using the AB phase (phase) algorithm to spatial and temporal frame grayscale configuration rule A and Rule B grayscale arranged in a staggered manner multiplex configuration, to achieve the effect of the visual center of gravity evenly distributed. 在时间上之分布,以第一列来说,帧T201的第一列从左至右分别为B、 A、 B、 A、 B、 A、 B、 A、 B、 A,下一帧T202的第一列从左至右分别为A、 B、 A、 B、 A、 B、 A、 B、 A, B。 The distribution in time to the first column, the first row from left to right frame T201 is B, A, B, A, B, A, B, A, B, A, of the next frame T202 the first row from left to right A, B, A, B, A, B, A, B, A, B. 接下来,再下一帧T203的第一列从左至右分别为B、 A、 B、 A、 B、 A、 B、 A、 B、 A,再下一帧T204第一列从左至右分别为A、 B、 A、 B、 A、 B、 A、 B、 A, B。 Next, the first row and then the next frame from left to right T203 B, A, B, A, B, A, B, A, B, A, and then a next column from left to right the first frame T204 are A, B, A, B, A, B, A, B, A, B. 可明 Keming

显看到时间分配交错的结果。 Significant allocation of time to see the results staggered.

在空间上之分配可参考帧T204,以帧T204的第一列至第二列来说,第一列从 Allocating space in the reference frame of the T204, the first row to the second row of the frame T204, the first column from

左至右为A、 B、 A、 B、 A、 B、 A、 B、 A, B,第二列从左至右分别为B、 A、 B、 A、 B、 Left to right, A, B, A, B, A, B, A, B, A, B, the second column from left to right B, A, B, A, B,

A、 B、 A、 B、 A。 A, B, A, B, A. 可明显看到空间分配交错的结果。 You can clearly see the results of space allocated staggered. 此作法因可分散人类的视觉重 This approach can be dispersed due to the human visual weight

心,所以能改善动态拟似轮廓现象。 Heart, we are able to improve the dynamic false contour phenomenon. 但当显示低灰阶亮度的静态画面时,由于两种 When the still picture display low gradation luminance but, since both

不同的灰阶亮度作切换,使得在某些亮度之下,会有两次点亮时间必须间隔一个帧 Different gray level for the switching, so that under certain brightness, there must be two lighting time interval of one frame

以上。 the above. 根据等离子显示器的发光特性,同一像素格(cell)在两次点亮时间相距越久越不容易被点亮,因此会造成熄点问题。 The emission characteristics of a plasma display, the same pixel grid (cell) is not likely to be worse and lit twice lighting time apart, thus causing problems quench point. 由于等离子显示器必须兼具能显示非静态与静态画面的功能,因此需要有一种方法,对于非静态画面与静态画面皆能具备 Since the plasma display must be able to display both static and non-static screen, it is necessary to have a method for non-static picture and the still picture includes Jieneng
