摘要： This invention relates to a method for driving a display panel (DP) having pixels (P). The display panel (DP) is driven with a sequence of image frames. The image frames are converted to a drive signal (V2) comprising refresh frames with a refresh frame period (TR) shorter than the image frame period. A pixel (P) of the display panel (DP) is driven with an adapted drive signal having a first polarity during a first group of refresh frame periods, and having a reversed polarity during a subsequent second group of refresh frame periods. The first group and the second group each comprise at least two refresh frame periods.

摘要： The invention is related to a receiver for a television signal, such as a PAL signal, the receiver comprising a color information retrieving unit (8, 9, 11, 13) arranged to separate color information from a composite signal to retrieve color information. The receiver contains a filter (13) for selecting the decoded color signal from a plurality of signals, under control of a first value (b) of the color information from the central linerelative to second and third values (a, c) of the color information at corresponding position on further lines at an odd number of lines from the central line on a first and second, mutually opposite side of the central line respectively. An average is selected in which the first value (b) is weighed equally with information from a line or lines at an odd number of lines from the central line, when the first value (b) is more than a predetermined factor outside a range between the second and third value (a, c). A signal derived from the color information is selected in which at least no information (a, c) is weighed from the first or second side when the first value (b) is in the range or less than said factor outside the range and closer to the third or second value (a, c) respectively.

摘要： The invention relates to a backlighting arrangement for a light valve display device, such as an LCD-display. The backlighting arrangement comprises a number of elongated light emitting structures (9) arranged in a layer (5), extending in a plane, which structures emit light along their lengths in the direction of a light valve layer (1). An optics layer (7), comprising a number of elongated lenses (11), is placed between the light emitting structures (9) and the light valve layer (1). Each such lens (11) concentrates light emitted by a number of light emitting structures (9) onto a number of elongated areas on the light valve layer (1). Preferably, each light emitting structure (9) emits light of one primary colour only, and the elongated lenses concentrate the light emitted from each light emitting structure onto sub-pixel areas intended for a corresponding colour, so that a colour display may be provided without the use of colour filters.

摘要： The invention relates to a TV-receiver 220 for receiving and decoding a broadcasted TV-signal representing an image and control data wherein the control data defines a vector indicating a location of a partition of important subject matter within said image. The invention further relates to an image display apparatus 200 and to a TV-system comprising the TV-receiver and to a method for operating the TV-receiver. It is the object of the present invention to improve a known TV-receiver 220, an image display apparatus, a TV-system and a method for displaying an image such that at least a partition of important subject matter within the original broadcasted image can entirely be shown on a screen even if the size of said screen is smaller than the size of said partition with only a minimal loss of details. This object is solved in that the control data further defines the size of said partition showing said important subject matter and that the TV-receiver 220 further comprises a re-sampling unit being adapted to extract a re-sampled image to be displayed on the screen of a display device 200 from said decoded image by re-sampling said decoded image at a variable re-sampling rate defined at the receiving end such that the size of the partition of important subject matter in the re-sampled image is adapted according to a criterion.
