Problems solved by technology

2D display modes of course do not provide stereoscopic images
[0011] The problem with using switchable LC microlenses is that it requires significant adaptations to the LCD manufacturing process compared to the manufacture of standard LCD panels.

Embodiment Construction

[0030] The present invention provides a switchable autostereoscopic display device comprising: a first LED display panel, an array of non-switchable lens elements and a second LED display panel. This arrangement avoids the need for a switchable lens array for switchable 2D / 3D display. The first LED display panel can simply be switched off so that the lens array is inactive in generating 3D output. The second LED display panel then generates the ideal 2D image.

[0031] figure 1 is a schematic perspective view of a known switchable autostereoscopic display device 1 for explaining the principle of operation of known LC-based systems. The display device 1 is shown in expanded form.

[0032] The known device 1 comprises a liquid crystal display panel 3 of active matrix type acting as a spatial light modulator to produce the display. The display panel 3 has an orthogonal array of display pixels 5 arranged in rows and columns. For clarity, only a small number of display pixels ...

Abstract

A switchable autostereoscopic display device comprises a first LED display panel, an array of non-switchable lens elements and a second LED display panel. This arrangement avoids the need for a switchable lens array to implement a switchable 2D / 3D display. The first LED display panel can simply be turned off so that the lens array does not play a role in generating a 3D output. The second LED display panel then produces the desired 2D image.

Description

technical field [0001] The present invention relates to an autostereoscopic display device of the type comprising a display panel having an array of display pixels for producing a display and a plurality of imaging means, e.g. microlenses, arranged above the display panel and seeing the display pixels through said display panel element. Background technique [0002] A known autostereoscopic display device is described in GB 2196166 A. The known device comprises a two-dimensional liquid crystal display panel having an array of rows and columns of display pixels, which acts as a spatial light modulator to produce the display. An array of elongated microlens elements extending parallel to each other overlies the array of display pixels, and the display pixels are viewed through these microlens elements. [0003] The microlens elements are provided as a sheet of elements, each element comprising an elongated semi-cylindrical lens element. The lenticular elements extend in the...
