[0086] The blue plane can be resampled using one of several filters, such as a 2×2 box filter,

[0087] 0.25 0.25

[0088] 0.25 0.25

[0089] Or a box-tent filter in the center of the blue subpixel:

[0091] 0.125 0.25 0.125

[0092] In one embodiment where color signal information is generated within primary color sub-pixels, each input pixel image data is mapped to two sub-pixels. There are also different ways of arranging the input image pixels by primary color sub-pixels to produce an area resampling filter for this purpose. Figure 10 (Excerpt from US2005 / 0225563 Image 6 ) shows a method for mapping four input image pixels to a Figure 9A Area resampling mapping of subpixels in the red plane of the display panel for the shown subpixel repeating group. Input image data again as Figure 5 Shown is depicted as an array or grid of cells 50, each cell 52 representing a color data value for an input image pixel. ...

Abstract

Display devices and systems are configured with display panels substantially comprising one of several embodiments of three primary color or multi-primary color subpixel repeating groups that are particularly suitable for directional display devices which produce at least two images simultaneously, such as autostereoscopic three-dimensional display devices or multi-view devices. Input image data indicating an image is rendered to a device configured with one of the illustrated subpixel repeating groups using a subpixel rendering operation.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims the benefit of priority to U.S. Provisional Application 60 / 889,724, filed February 13, 2007, entitled "SUBPIXEL LAYOUTSAND SUBPIXEL RENDERING METHODS FOR DIRECTIONAL DISPLAYSAND SYSTEMS," the entire contents of which are incorporated herein by reference. technical field [0003] The subject matter of the present invention relates to a spatial light modulator, in particular to a sub-pixel layout of a spatial light modulator for use in directional display devices or systems such as three-dimensional (3D) autostereoscopic display devices or multi-view displays. Background technique [0004] A display device capable of simultaneously generating at least two different images is referred to herein as a directional display device. A directional display produces at least two different images, each of which is viewable from a different viewing orientation. In one type of directional display device, the t...
