Abstract: Subject matter disclosed herein relates to improving luminance and reducing color shifts in electrowetting displays. The electrowetting display comprises a plurality of electrowetting elements separated by partition walls and spacers. The spacers and/or partition walls are reflective. When incident light that enters a pixel or subpixel is reflected and encounters a spacer and/or partition wall, the light is reflected such that the reflected light exits the pixel or subpixel into which the incident light entered. This improves luminance and reduces color shifts of the electrowetting display.

Abstract: An electrowetting display comprises a support plate on which individual electrowetting pixels separated from one another by pixel walls are formed. The individual electrowetting pixels include an electrode layer on the support plate, a dielectric barrier layer on the electrode layer, a hydrophobic layer on the dielectric barrier layer, and quantum dots between the hydrophobic layer and the electrode layer. The quantum dots may utilize blue or white light illuminating the pixels to emit longer-wavelength colors such as red and green. Such a feature may enhance or replace functionality of color filters.

Abstract: A display device (120) has a 3D display (160) for emitting at least two views of 3D image data to enable autostereoscopic viewing of 3D image data at multiple viewing positions (182, 184). A processor (140) processes the 3D image data (122) for generating the views for display on the 3D display, and a viewer detector (130) detects a viewer position of a viewer in front of the 3D display. The processor has a viewer conflict detector (141) for detecting and resolving viewer position conflicts. The detector obtains at least a first viewer position of a first viewer via the viewer detector, and detects a viewer position conflict at the first viewer position where said first view and second view do not provide the 3D effect for the first viewer. If so, the detector controls generating the views in dependence of the detected viewer position conflict. At least one of said at least two views as received by the first viewer is dynamically modified to signal or resolve the conflict.

Abstract: 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.

Abstract: 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.

Abstract: A method of gamut mapping maps an input image composed of pixels and having an input gamut (IG) defined by input RGB primaries (Ri, Gi, Bi) to a reproduction gamut (RG) defined by reproduction RGB primaries (Ro, Go, Bo). The reproduction gamut (RG) is narrower than the input gamut (IG). An input signal (RGBin) defined with respect to the input RGB primaries (Ri, Gi, Bi) is color transformed (1) into a transformed signal (RGBt) defined with respect to the reproduction RGB primaries (Ro, Go, Bo), whereby color information of the pixels (P1, P2, P3) within the reproduction gamut (RG) is preserved. Scaling factors (SFi) indicating a distance between on the one hand pixels (P1, P2, P3) of the transformed signal (RGBt) which are outside the reproduction gamut (RG), and on the other hand an edge of the reproduction gamut (RG) are determined (2).

Abstract: 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.

Abstract: A color gamut mapping maps an input image signal which has input pixel colors defined by an input luminance and an input chromaticity into a mapped image signal which has corresponding mapped pixel colors defined by a mapped luminance and a mapped chromaticity for a display. The input pixel colors lie within the input color gamut different than the display color gamut. The desired mapped luminance may be retrieved by looking up stored desired luminance values in a look-up table at the mapped chromaticity, or by calculating a relative to white luminance, or a luminance decrease, etc.

Abstract: 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.
