摘要:
The invention relates to an AC plasma display panel (12) of the surface discharge type, and more specifically to the structure of the address electrodes (5) of the panel and of the phosphor elements, and to a plasma display panel device comprising such a panel. According to the invention, only one address electrode (5) is used for one out of every two columns. Scan electrodes (8) and common electrodes (7) may comprise transparent parts (11). These parts (11) may extend over one out every two cells in a checkerboard fashion. In a preferred embodiment, the columns may have alternating wide (15) and narrow (16) cells (2). Furthermore, each cell has a neighbor-cell of the same color on the same address electrode but in a neighboring column and in a neighboring row. The display panel device comprises a driving circuit (22) arranged such that in at least one of the sub-fields the neighboring cells are addressed simultaneously.
摘要:
A display device comprising a light guide (12), a front plate (14), and an intermediate electromechanically operable foil (16). Two electrode layers (22, 23) are arranged on either side of the foil (16) to induce electrostatic forces on the foil (16) and to bring selected portions of the foil into contact with the light guide (12), thereby extracting light from the light guide (12). The second electrode layer (22) is arranged on the opposite side of the light guide (12) with reference to the foil (16), and separated from the light guide (12) by means of a refractive layer (28). As no electrode layer is required on the light guide itself, the light path of rays extracted from the light guide is cleaner, and the absorption of light is reduced. The light guide can have a thickness such that the light extracted from the light guide per unit length is sufficient to allow for line-at-a-time addressing.

The invention provides a collimator comprising a first collimator face, a second collimator face, and a stack region. The stack region comprises a first layer having a first prismatically shaped top face with a plurality of 1D arranged first prisms having first prism axes, and a second layer having a second prismatically shaped top face with a plurality of 1D arranged second prisms having second prism axes. The first and second prism axes are in a crossed configuration. In a direction from the first collimator face to the second collimator face, the index of refraction of material upstream of the first prismatically shaped top face is larger than that of material downstream of the first prismatically shaped top face, and the index of refraction of material upstream of the second prismatically shaped top face is larger than that of material downstream of the second prismatically shaped top face.

An autostereoscopic display device includes a reflection layer for reflecting at least a portion of incident light, a polarization conversion layer arranged over the reflection layer, and an array of lenticular elements arranged over at least a portion of the polarization conversion layer and including a birefringent material. Light having a first state of polarization is configured to pass through the lenticular element array without substantial lenticular element focusing, where the polarization state is transformed by the polarization conversion layer such that the reflected light has a second state of polarization. Light having the second polarization state passes through the lenticular element array with the lenticular element focusing to provide multiple views to different viewing locations.

A method of computing a display value to be provided to a stereoscopic display apparatus (150) is described. The method includes: determining a first intermediate value (811) from a 3-D representation on basis of a first one of the angular directions and coordinates of a first one of the picture elements (102); determining a second intermediate value (810) from the 3-D representation on basis of a further angular direction relative to the first plane and the coordinates of the first one of the picture elements; and combining the first intermediate value (811) and the second intermediate value (810) to the display value, the display value related to the particular output of a first one of the picture elements of the stereoscopic display apparatus (102).

An autostereoscopic image output device comprises an image panel having an array of image pixels (5) defining an image, the image pixels being arranged in rows and columns. An array of parallel lenticular elements (11) is positioned over the image panel, the lenticular elements having optical focal axes that are slanted at an angle (φ) to the image pixel columns. The image output device is operable in first and second modes, with the image panel and lenticular element array rotated by 90 degrees between the modes, thereby providing a landscape mode of operation and a portrait mode of operation, the slant angle φ in the landscape mode satisfies: 1≧tan φ≧1/2. This enables a 3D image device to be used in both the landscape and the portrait mode, while maintaining a good view-distribution and image pixel structure.
摘要:
A display unit comprising electro-wetting pixels (1300) is provided. The inventive pixels (1300) provide bistable or multi-stable pixel states and thus facilitates passive matrix addressing. For this purpose an additional electrode (1305) is arranged for each multi-stable state. Consequently, each pixel comprises one counter electrode (1306) and at least one pair of address and retain electrodes (1304, 1305). In order to activate a pixel, an address potential is applied to the address and retain electrodes (1304, 1305) in relation to the counter electrode (1306), and in order to deactivate a pixel the potential is removed. In order to retain a current pixel state a retain potential is applied to only the retain electrode (1305) in relation to the counter electrode (1306); the current pixel state, be it active or passive, will then be preserved and the retain potential configuration thus provides a bistable pixel state.
摘要:
An autostereoscopic display device has an array (9) of lenticular elements (11) overlying a display panel (3), the lenticular elements comprising electro-optic material (23) and being switchable to enable 2D and 3D viewing modes. The electro-optic material, for example liquid crystal material, is contained adjacent an optically transparent layer in the form of a lenticular body (21). A birefringent material is utilized for the lenticular body, preferably with the ordinary and extra-ordinary index of refraction substantially matching that of the electro-optic material.
