摘要： A method and a device for displaying an image on an Organic Light Emitting Display where a frame is divided into two groups of subframes are provided for flicker-free and very high level motion rendition. The first group of sub-frames and the at least second group of sub-frames comprise corresponding sub-frames and constitute each a complete image in a video frame and corresponding sub-frames of two groups of sub-frames have similar but not automatically the same duration. 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 gray scale 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.

摘要： 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 for displaying at least a second grayscale level of a pixel of the image during at least a second group of sub-frames. The first group of sub-frames and the at least second group of sub-frames 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.

摘要： 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.

摘要： The noise occurring when applying dithering on a transfer function shall be reduced. Therefore, a first output value and a second output value are associated to a discrete input value of the transfer function. On the basis of a given number of dithering bits, an intermediate value being equal to and/or lying between the first output value and the second output value and using the least number of dithering bits is chosen. Finally this intermediate value is taken as an output value for the discrete input value. Thus, the dithering noise can be reduced tremendously.

摘要： With the new plasma display panel technology new kinds of artefacts can occur in video pictures. These artefacts are commonly described as “dynamic false contour effect”, since they correspond to disturbances of gray levels and colors in the form of an apparition of colored edges in the picture when the observation point on the PDP screen moves. According to the invention, such an artefact is compensated by analyzing the pictures, and determining the pixels which need to be corrected. The digital sub-field code words of these pixels are replaced by corrected sub-field code words. Thereby, the correction sub-fields (C1, C2, C3) which are inserted in or omitted from the digital code word are selected under consideration of its position within the frame period for optimal results.

摘要： The present invention relates to a method and an apparatus for processing video pictures especially for dynamic false contour effect and dithering noise compensation. The main idea of this invention is to divide the picture to be displayed in areas of at least two types, for example low video gradient areas and high video gradient areas, to allocate a different set of GCC (for Gravity Center Coding) code words to each type of area, the set allocated to a type of area being dedicated to reduce false contours and dithering noise in the area of this type, and to encode the video levels of each area of the picture to be displayed with the allocated set of GCC code words. In this manner, the reduction of false contour effects and dithering noise in the picture is optimized area by area.

摘要： With the new plasma display panel technology new kinds of artifacts can occur in video pictures due to the principle that brightness control is done with a modulation of small lighting pulses in a number of periods called sub-fields. These artifacts are commonly described as ‘dynamic false contour effect’. A technique called bit line repeat coding has been developed for reducing the false contour effect. According to this technique sub-field coding is done with common (CSF) and normal sub-fields (SF) where for the common sub-fields (CSF) identical entries in the sub-field code words of two or more corresponding pixels on two or more pixel lines are used. In this specific sub-field coding method some cases will occur in which an error has to be made due to the reduced flexibility in encoding produced by the need to have the same code on common sub-fields (CSF). The general idea of the invention is now to put the coding failures on the higher video levels of the two or more pixels being grouped together. Further improvements concern picture content analysis and or motion detection for controlling the switching between different sub-field coding modes and a specific adapted dithering pattern for use with bit line repeat coding.
