    • The present invention relates to a method of displaying a video image on a digital display device and particularly on a plasma display panel. According to the invention, the cells of the device change state at most once during the image display period and the subscans of this display period are two types. The subscans of the first type address two adjacent rows of the panel simultaneously and the subscans of the second type address each row of cells of the panel individually. In certain cases, the grey level delivered to the cells is modified before display. For two neighbouring cells sharing the same subscans of the second type and displaying the grey levels A and B, one of the grey levels, A or B, is modified if the first subscan for which one of the cells changes state is a subscan of the first type.

    • Plasma Display Panels (PDP) are becoming more and more interesting for TV technology. One important criterion for picture quality is the Peak White Enhancement Factor PWEF. From a previous patent application of the applicant it is known to have a table of power level modes in a control unit (21) for the display device. The average picture power value is measured and a corresponding power level mode will be selected from the table for sub-field coding. The power level modes have been made variable in respect to a number of parameters, namely: the number of sub-fields, the sub-field type, the sub-field positioning, the sub-field weight, the sub-field pre-scaling, a factor for the sub-field weights which is used to vary the amount of small pulses generated during each sub-field. According to the invention it is now proposed to use one or both of the following parameters in addition for varying the power level modes: the sustain frequency, the sustain pulse slope.

    • The invention deals with the large area flicker effect reduction in display devices like plasma display panels, in which the light output is controlled by small pulses over a whole frame period and the amount of small pulses determine the brightness of the light output. The invention proposes an adaptation of the known principle of sub-field grouping for large area flicker reduction for the specific sub-field coding process called incremental sub-field coding, in which only those sub-field code words are taken for display driving having the characteristic that there is never a sub-field inactivated between two activated sub-fields or never a sub-field is activated between two inactivated sub-fields.For this specific sub-field coding it is proposed to make the sub-field grouping in a simple manner, where all the odd sub-fields are grouped together in one group (G1) and all the even sub-fields are grouped together in a second group (G2). Despite the fact that some luminance differences are present in the groups it has been proved, that this sub-field grouping leads to a very efficient large area flicker reduction because of its complementary behaviour to the required dithering technique.
    • 本发明涉及诸如等离子体显示面板的显示装置中的大面积闪烁效应的降低,其中光输出在整个帧周期内由小脉冲控制,并且小脉冲的量决定光输出的亮度。 本发明提出了对于称为增量子场编码的特定子场编码处理的用于大面积闪烁减少的子场分组的已知原理的适应,其中仅采用那些子字段代码字用于具有 在两个未激活的子场之间激活两个激活的子场之间从未有子场的子场的从未被激活的特征。对于该特定的子场编码,建议将子场分组置于 其中所有奇数子场在一组(G1)中组合在一起,并且所有偶数子场在第二组(G2)中分组在一起。 尽管已经证明在组中存在一些亮度差异的事实,但是由于其对所需的抖动技术的补充行为,该子场分组导致非常有效的大面积闪烁降低。

    • The invention is related two a new kind of pre-processing for plasma display panel control. The plasma display technology has the drawback of a reduced grey scale portrayal. This is due to the fact that contrarily to CRTs where luminance is approximately quadratic to the applied cathode voltage, luminance is linear to the number of discharge pulses in PDPs. Therefore, an approximately quadratic degamma function has to be applied to the input video signal components R,G,B before sub-field coding can be done. Truncation to 8-bit video data is required, so that the effect of the degamma function cannot be fully maintained. Especially in the region of small video levels, where the eye sensitivity is high, the grey scale portrayal is poor.According to the invention it is proposed to use a new kind of dithering, adapted to the PDP specialities to improve the grey scale portrayal. These adaptation includes three dithering specialities which can be used singly or in combination. These are: cell-based dithering, i.e. to each colour component R, G, B of a pixel separate dithering numbers are added; object/region-based dithering, i.e. the set of disposable dithering numbers is made dependent on the region/object in the video picture; the set of disposable dithering numbers is made dependent on the video (signal) level.
    • 本发明涉及两种用于等离子体显示面板控制的新型预处理。 等离子体显示技术具有减少灰度图形的缺点。 这是由于与对应于阴极电压的亮度近似二次的CRT相反,亮度与PDP中的放电脉冲数呈线性关系。 因此,在可以进行子场编码之前,必须对输入视频信号分量R,G,B施加近似二次去波函数。 需要截断到8位视频数据,因此不能完全维持反射功能的效果。 特别是在小视频水平的地区,眼睛的敏感度高,灰度图形差。根据本发明,提出了一种适用于PDP专业的新型抖动,以改善灰度图形。 这些适应性包括可以单独使用或组合使用的三种抖动特性。 这些是:基于单元的抖动,即添加像素分开的抖动数的每个颜色分量R,G,B; 基于对象/区域的抖动,即一组抖动数量的集合取决于视频图像中的区域/对象; 该组一次性抖动数字取决于视频(信号)电平。
