Problems solved by technology

Unfortunately, round lenses lead to increased resolution loss
For example, to create 9 viewpoints vertically and horizontally, a circular lens will gain a resolution loss of a factor of 9×9, which is unacceptable for most applications

Embodiment Construction

[0048] The present invention provides a switchable autostereoscopic display device, in which an imaging device including an electrically configurable gradient index lens array directs outputs from different pixels to different spatial positions, so that the stereoscopic image can be viewed. The imaging device is electrically switchable in at least three modes, the at least three modes including a 2D mode and two 3D modes. This enables the display to be configured in a single design by the imaging device for different resolutions, multiple viewpoints or display directions.

[0049] figure 1 It is a schematic perspective view of a known autostereoscopic display device 1 directly viewed. This known device comprises a liquid crystal display panel 3 of the active matrix type, which is used as a spatial light modulator to produce a display.

[0050] The display panel 3 has an orthogonal array of display pixels 5, which are arranged in rows and columns. For clarity, only a small number ...

Abstract

A switchable autostereoscopic display device comprises a display panel having an array of display pixels for producing a display, the display pixels being arranged in rows and columns; and an imaging arrangement for directing the output from different pixels to different spatial positions to enable a stereoscopic image to be viewed. The imaging arrangement is electrically switchable between at least three modes comprising a 2D mode and two 3D modes. The imaging arrangement comprises an electrically configurable graded index lens array. The display can be switched between a number of modes to enable the display to be adapted or to adapt itself to the image content to be displayed and / or the display device orientation.

Description

Technical field [0001] The present invention relates to an autostereoscopic display device, which includes a display panel having a display pixel array for generating a display, and an imaging device for directing different viewpoints to different spatial positions. Background technique [0002] The first example of an imaging device for such a display is a fence, for example, having a slit that is sized and positioned relative to the lower layer pixels of the display. If the viewer's head is at a fixed position, he / she can perceive a 3D image. The fence is placed in front of the display panel, which is designed to direct the light from the odd and even pixel columns to the left and right eyes of the viewer. [0003] The disadvantage of this dual-view display design is that the viewer must be in a fixed position and can only move about 3 cm to the left or right. In a more preferred embodiment, there are not two sub-pixel columns under each slit, but some. This allows the viewer ...
