    Abstract: 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.

    Abstract: 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.
