Abstract: Response fidelity problems appear for some specific video levels at PDP borders. The reason is that some cells at the border of the PDP panel are not completely closed and pollute when switched ON neighbouring cells being OFF. Therefore, it is suggested to encode the video levels in the border area in a specific way. Especially, for critical subfields within the code it is forbidden to insert a binary 0 between two binary 1. Thus, the neighbourhood of critical sub-fields being ON and OFF is avoided. Preferably, the specific border coding is performed under the control of an average power management (2) and codewords being not used are recreated by dithering (6).

Abstract: A plasma display panel is a pure linear display and does not provide a nonlinear gamma behaviour like a CRT so that an artificial gamma function has to be applied to the signal in digital form. This gamma function increases the quantization steps in the dark areas whereas the quantization steps will be reduced in the luminous reas. The basic idea is to apply an adaptive noise filtering after the gammatization process. The adaptive filtering is a specific filtering which is adapted to the gammatization quantization noise. In other words, the filtering will be maximum for dark areas and its efficacy will be automatically decreased when the luminance of the area is increasing.

Abstract translation: 等离子体显示面板是纯线性显示器，并且不提供诸如CRT的非线性伽马行为，使得人造伽马功能必须以数字形式应用于信号。 该伽马函数增加了暗区域中的量化步长，而在发光区域中量化步长将会减小。 基本思想是在恶意化过程之后应用自适应噪声滤波。 自适应滤波是适应于伽玛化量化噪声的特定滤波。 换句话说，对于暗区域，过滤将是最大的，并且当区域的亮度增加时，其功效将自动降低。

Abstract: The number of available sub-fields for stereoscopic displaying on plasma display panels is not high enough to insure a good grey-scale portrayal as well as a good false contour behaviour. Thus, the number of sub-fields is artificially increased by commonly addressing the sub-fields of two or more pixel lines so that the addressing time of the panel may be decreased for each sub-field.

Abstract: The driving of an active matrix organic light emitting display (AMOLED) shall be improved. A pulsing grayscale rendition shall be combined with an improved motion rendition when driving the AMOLED with analog signals. Therefore, there is provided a data signal which is applied to each cell of the AMOLED for displaying a first grayscale level of a pixel of the image during a first group of sub-frames (SFO to SF5)for displaying at least a second grayscale level of a pixel of the image during at least a second group of sub-frames (SF' 0 to SF' 5). The first group of sub-frames (SFO to SF5) and the at least second group of sub-frames (SF' 0 to SF' 5) are constituting a video frame N. Each group of sub-frames is divided into a plurality of sub-frames. Each, the first group of sub-frames and the second group of sub-frames is belonging to a separate complete image of the display (AMOLED). The data signal of a cell comprises plural independent elementary data signals wherein each of the elementary data signals is applied to the cell during a sub-frame and the grayscale level displayed by the cell during the respective group of sub-frames depends on the amplitude of the elementary data signals and the duration of the sub-frames. With this concept, a flicker- free and a very high level of motion rendition can be offered.

Abstract: For reducing the false contour effect the gravity centre coding (GCC) is utilized. However, a GCC with a few number of levels introduces noise in a picture. Therefore, each picture is divided into segments and such GCC is performed only in regions, where the false contour effect is critical. This is the case for skin areas of a picture. Such areas are detected by the colour analysis (1, 2) and texture analysis (3, 4). If this analysis leads to a skin area, a specific false contour mode (5) for data processing is used. Other­wise, a standard mode (6) is employed.

Abstract: The present invention relates to a grayscale rendition method in an active matrix OLED (Organic Light Emitting Display) where each cell of the display is controlled via an association of several Thin-Film Transistors (TFTs). In order to improve the grayscale rendition in an AM-­OLED when displaying low grayscale levels and/or when displaying moving pictures, it is proposed to split each frame into a plurality of subframes wherein the amplitude of the data signal applied to a cell of the AM-OLED can be adapted to conform to the visual response of a CRT display. According to the invention, the video frame used for displaying an image is divided into N consecutive subframes, with N≥2, and the data signal applied to the cell comprises N independent elementary data signals, each of said elementary data signals being applied to the cell during a subframe. The grayscale level displayed by the cell during the video frame is depending on the amplitude of the elementary data signals and the duration of the subframes.

According to the invention, a different set of reference voltages is used for each colour component. To this end, the video frame is divided into at least three sub-frames and at least one colour component of the picture is addressed during each subframe with a set of reference voltages adapted to said color component.
