摘要： A method and apparatus for reducing false contour in a digital display apparatus including a plasma display panel (PDP) using pulse number modulation are provided. The apparatus includes a data converter, which processes an image signal such that a gray level of the image signal exists within a predetermined range; an error diffuser, which diffuses an error between a gray level of a current pixel in a current frame of the image signal and a gray level of the current pixel in the current frame after being subjected to gray-level change, to pixels adjacent to the current pixel in the current frame; a gray-level changing unit, which calculates a difference in a gray level between each pixel in the current frame of the image signal and a pixel corresponding to the current frame pixel in a previous frame of the image signal, and changes the gray level of the current frame pixel based on the gray level difference such that transition in an emission pattern of higher weighted subfields among subfields, which illuminate according to the gray level of the current frame pixel, between the current frame pixel and the previous frame pixel is minimized; and a subfield converter, which converts a subfield according to a gray level output from the gray-level changing unit.

摘要： A PDP driving method that reduces the reset voltage of the PDP driving waveforms to make it possible to use low-voltage elements and to achieve high contrasts is disclosed. Since conventional PDP waveforms require very high reset voltages, it causes a problem of intense background light emissions, low contrasts, use of high-voltage components, and increased circuit costs. According to the driving waveforms of the present invention, relative voltage differences between the address electrode and the X electrode and between the X electrode and the Y electrode are considered to design waveforms of low reset voltages, thereby providing high contrasts and low-cost circuit.

摘要： The invention is related to 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 color 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.
摘要翻译：本发明涉及一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。
