摘要： A display system comprises a color sequential display (201) having a backlight (205) comprising several backlight segments and a light modulating panel (207) comprising pixels having controllable light transmission. A backlight unit (211) determines, for a plurality of backlight segments, backlight chromaticities for fields of an image in response to the image content. An order unit (217) determines a sequential order of the backlight chromaticities for each of the plurality of backlight segments for the image in response to the chromaticities. A driver (219) generates a backlight drive signal for the backlight (205) corresponding to the chromaticities and sequential order. A modulating processor (213) determines light modulating values for the pixels in response to the chromaticities, the sequential order and the image. A driver (221) then generates a light modulating drive signal for the light modulating element corresponding to the light modulating values. The system may improve image quality by reducing spatial cross-talk between the backlight segments.

摘要： A controller for a multi-primary display having M>3 primaries receives a set of input N-primary image color defining values comprising drive values for N primaries for each pixel. A compensator (317) generates a set of compensated N-primary image color (N>=3) defining values by applying a luminance compensation to the values of the set of input N-primary image color defining values where the luminance compensation for each pixel depends on the chromaticity of the pixel. A backlight processor (311) determines backlight levels in response to the compensated N-primary image color defining values. A modifier (313) then generates modified N-primary image color defining values by adjusting the input or the modified N-primary image color defining values or the for the backlight level and a primary converter (315) converts the modified N-primary image color defining values into multi-primary drive values for the display. The approach may e.g. reduce clipping for multi-primary displays with dynamic backlight control by introducing a low complexity pre- processing luminance compensation to existing equipment.

摘要： A multi-primary display with more than three additive primaries comprises a spatial repetition of a pixel repetition block. The block comprises a first pixel row (1201) of pixels of primaries. Each pixel is divided into a plurality of sub-pixels including at least a higher luminance sub-pixel adjacent to a lower luminance sub-pixel. The first pixel row (1201) forms a first sub-pixel row (1203) and a complementary sub-pixel row (1205) adjacent to each other and comprising complementary sub-pixels. The sub-pixels are arranged such that a difference between a first combined maximum luminance for higher luminance sub-pixels of the first sub-pixel row (1203) and a second combined maximum luminance for higher luminance sub-pixels of the complementary sub-pixel row (1205) is no more than 30% of a sum of the first combined maximum luminance and the second combined luminance. The invention may provide an improved display with e.g. reduced pixel structure visibility.

摘要： A backlight for a display comprises a group of elongated light guides (209, 211, 213) arranged to illuminate an elongated strip (203) of the display. Each of the elongated light guides (209, 211, 213) comprises a light in-coupling for receiving light and at least one light out-coupling (217, 219, 221) for radiating light where the light out-couplings (217, 219, 221) have a restricted extension in a longitudinal direction of the elongated light guides (209, 211, 213). Each of the plurality of light sources (215) are arranged to feed light to a light in-coupling of one of the plurality of elongated light guides (209, 211, 213). The light out-couplings (217, 219, 221) for the elongated light guides (209, 211, 213) have different offsets along the longitudinal direction of the elongated strip. The approach may allow a two-dimensional segmentation of the backlight using substantially one dimensional light guides thereby providing a local dimming backlight based on edge illuminating light sources. Thus, low complexity, cost and display depth can be achieved.

摘要： An apparatus generates a derived image signal for a display (101) having a backlight (105) and a light modulating display panel (107). An input image is represented by pixel values in accordance with a color representation having a first reproducible gamut. A backlight driver (111) determines a backlight driving signal corresponding to a presentation of the image on the display (101) in accordance with an image rendering criterion. A processor (113) determines a first set of primary color vectors corresponding to a rendering gamut in response to the backlight driving signal. It then determines a second set of color vectors defining directions in which a degree of freedom for adding luminous energy to the derived image signal exists, given as a constraint the first set of primary color vectors. An image enhancer (115) performs an image enhancement which increases local color modulator drive values for local colors in accordance with the degree of freedom.

摘要： A display panel control apparatus receives an image to be displayed by a display panel (103) in at least a first field and a second field. A first driver (107) generates a first drive signal for a pixel for the first field in response to an image pixel value and a second driver (109) generates a second drive signal for the pixel for the second field in response to the image value. The first and second drive levels correspond to first and second radiated luminance levels respectively from the pixel. The first and second radiated luminance levels are different and have a combined radiated luminance corresponding to the luminance level for the pixel. The first and second drive signals are selected from a first and second set of quantized values which are arranged to provide more discrete values of the combined radiated luminance than are included in the first and second sets.
