A hybrid multiplexed 3D display and a displaying method thereof. The hybrid multiplexed 3D display includes an image display, a light source and an image splitter. The image display generates a view image. The light source sequentially generates light of multiple colors transmitted through the image display. The image splitter disposed above or below the image display causes image data, which is generated after the light is transmitted through the image display, to emit toward two or more than two view directions. Thus, the image viewed by a user has at least two views to achieve a stereoscopic visual effect.

Methods of driving colour sequential displays

Номер: US20120007899A1
Автор: Henricus Joseph Cornelus Kuijpers, Jan Van Der Horst
Принадлежит: KONINKLIJKE PHILIPS ELECTRONICS NV

A method of driving a display uses first ( 4 ) and second ( 5 ) illumination cycles of the display. In each cycle, a first set of pixels ( 1′ ) is illuminated with a first color (R, G) and a second set of pixels ( 2′ ) is illuminated with a second color (G, B). The first and second colors of the two cycles together include at least three colors (R, G, B) for forming an image. This method provides a sequential drive scheme, in that at least two cycles are used with different color properties. However, each cycle uses at least two different colors, so that each cycle is not a single color across the whole display area. In this way, the color sequence is alternated spatially as well as temporally.

Entropy coder supporting selective employment of syntax and context adaptation. In video coding, different entropy coding is selectively and adaptively employed based on local and/or remote consideration(s). For example, certain entropy coding may be context adaptive while other entropy coding may be non-context adaptive, and may operate in accordance with syntax or without syntax. Selective adaptation between context adaptive entropy coding and non-context adaptive entropy coding, as well as those which operate using syntax or without syntax may be made based on one or more local and/or remote characteristic(s). Transitioning between the various end to end configurations midstream can occur upon reference frame transitions with appropriate header information leadoff in a given bitstream. A given device (e.g., encoder or transcoder) may be implemented to transition independently, in cooperation with, or under the direction/coordination with one or more other devices within the communication system.

Rendering adjustments to autocompensate for users with ocular abnormalities

A digital screen rendering resolution adjustment can allow users who are conventionally dependent upon corrective lenses to view the digital screen to, after the resolution adjustment, view the contents of this screen with 20×20 vision (considered normal vision), without the use of these corrective lenses. A linear algebraic transform (performing essentially the inverse of the Lensmaker's Equation) can be applied and enact matrix manipulation that when rendering the graphical display to autocompensate for a viewer's visual abnormalities, can result in a distorted screen that is equivalent to the inverse of a corrective lens prescription. A screen rendering customization to autocompensate for a user's visual impairment can be applied for each eye in 3D capable devices due to the inherent nature of 3D to display separate images per eye. A unique algebraic transform matrix manipulation can be performed for each of the two images and can provide a more exact corrective lens prescription rendering simulation than for single image rendering for a display.

A frame buffer image comprising per-pixel packed color channels is transformed to a frame buffer image comprising regions corresponding to the color channels with vertical blanking regions inserted between color sub-field regions. Each region of the transformed frame buffer image is sequentially transmitted to the color field sequential display device for display of the corresponding color channel. Backlight illumination for each color channel is controlled by the GPU for temporal alignment with display of each color channel during a vertical blanking interval. The GPU may compensate an individual pixel's color channel value based on a corresponding previous color channel value in order to minimize crosstalk between neighboring color fields.

The occurrence of crosstalk in a display device which performs 3D display is suppressed. When 3D display is performed, part of a plurality of pixels perform desired color display and the other part of the plurality of pixels perform black display. Thus, as compared to the case where all of a plurality of pixels perform desired color display, the occurrence of crosstalk can be suppressed. A plurality of pixels which perform desired color display are changed depending on the display state. Therefore, as compared to the case where a plurality of pixels which perform desired color display are fixed when 3D display is performed, the display device can have a longer period until display change in a pixel becomes obvious (a longer lifetime) and variations in display among the plurality of pixels can be reduced.
