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.

The display panel (11) comprises a plurality of pixels (41, 42) arranged in rows and columns, each pixel (41, 42) comprising at least four sub-pixels having different colors, the sub-pixels being arranged in two sub-rows and at least two sub-columns, the arrangement of the two sub-rows of two adjacent pixels in the same row being interchanged. The striped polarizer (12) overlays the display panel (11) and comprises stripes (13, 14) of transparent polarizing material, the stripes (13, 14) being arranged in an alternating pattern of left eye stripes (13) and right eye stripes (14), wherein the left eye stripes (13) are arranged for converting light to a first polarization and are overlaying one sub-row of the two sub-rows and wherein the right eye stripes (14) are arranged for converting light to a different second polarization and are overlaying the other sub-row of the two sub-rows. The display controller (15) is arranged for using sub-pixel rendering for controlling a light output of the pixels in accordance with a 3D image to be displayed.

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.

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.
