Autostereoscopic display based on two-layer lenticular lenses

Abstract

An autostereoscopic display based on two-layer lenticular lenses is proposed. The two-layer lenticular lenses include one-layer conventional lenticular lenses and additional one-layer concentrating-light lenticular lenses. Two prototypes of the proposed and conventional autostereoscopic displays are developed. At the optimum three-dimensional view distance, the luminance distribution of the prototypes along the horizontal direction is measured. By calculating the luminance distribution, the crosstalk of the prototypes is obtained. Compared with the conventional autostereoscopic display, the proposed autostereoscopic display has less crosstalk, a wider view angle, and higher efficiency of light utilization.

“…The crosstalk measurement C i (x) of these multiview autostereoscopic displays is defined by Equation (5) [15,16]:…”

A large depth of field frontal multi-projection three-dimensional display with uniform light field distribution

“…The crosstalk at the boundary of two adjacent views is nearly 0.75, and the average crosstalk is 0.316. The autostereoscopic 3D display usually exhibits a large crosstalk, such as the maximum crosstalk of 1.05 [15] and the average crosstalk 0.383 [20]. According to the degree of crosstalk, a good image definition is presented.…”

Polymeric-lens-embedded 2D/3D switchable display with dramatically reduced crosstalk

“…Crosstalk may come from several aspects, such as misalignment between the lens array and the pixel plane, thermal expansion of the lens array after long-term use [19], as well as lens profile deformation introduced during fabrication process [26]. To simplify the discussion, let us assume the lens is well fabricated and the alignment is perfect so that we will focus on optimizing the display panel and lens array to reduce crosstalk.…”

“…Many approaches have been proposed to reduce crosstalk. Some of them are based on image processing [17], while the mainstream approach is based on optimizing the optical system, such as a specifically designed pixel mask for projection display [18], combined lens structures [19,20], pixel optimization by modifying the layout of light blocking components [21], and using triplet structures for reducing crosstalk at large angles [22].…”
