Problems solved by technology

As a result, the viewer's visual system may not be able to produce the expected stereoscopic effect due to the cross-talk phenomenon in which the left-eye image and the right-eye image interfere with each other

Embodiment Construction

[0027] The invention relates to a stereoscopic image display. The stereoscopic image display of the present invention does not require the user to wear stereoscopic image glasses to experience the visual effect of the stereoscopic image. The stereoscopic image display of the present invention includes a display panel, a lens structure layer and a backlight module, wherein the backlight module includes a brightness enhancement film for increasing the overall brightness. Utilizing the image arrangement and the beam splitting function of the cylindrical lens of the lens structure layer, the left and right eyes of the observer can respectively receive the corresponding left-eye image and right-eye image to provide a stereoscopic image. Moreover, the present invention reduces the degree of light divergence by adjusting the angle between the prisms of the brightness enhancement film and the lenticular lenses of the lens structure layer, thereby reducing the crosstalk phenomenon of m...

Abstract

The invention discloses a stereoscopic image display, which comprises a display panel, a lens structure layer and a backlight module, wherein the lens structure layer is arranged on the surface of the display panel and is used for separating and displaying images; the backlight module comprises a luminous device and at least one layer of brightness enhancement film; the display panel receives light rays of the backlight module and generates a plurality of display images; and the surfaces of the brightness enhancement film and the lens structure layer are provided with a plurality of prisms and a plurality of lenticular lenses respectively, wherein the prisms and lenticular lenses intersect in the axial direction. In the stereoscopic image display, due to a structure generated by intersecting the prisms and lenticular lenses in the axial direction, the advancing direction of the light rays is vertical to a plane of the display panel; therefore, overlap interference of other adjacent display images on corresponding display images is reduced.

Description

technical field [0001] The present invention relates to a stereoscopic image display, in particular to a stereoscopic image display that reduces crosstalk. Background technique [0002] At present, due to the improvement of display technology and the progress of display hardware, there are more and more three-dimensional flat-panel displays on the market that can provide viewers with three-dimensional visual effects. Since the angles of observing objects with the human eyes are slightly different, it is possible to distinguish the distance of objects and produce stereoscopic vision. The stereoscopic flat panel display uses this principle to separate the images seen by the left and right eyes to provide the viewer with a stereoscopic effect. In the past, viewers had to wear glasses with different colors or lenses with different polarizing effects to achieve the effect of image separation. Lenticular lens technology can separate images through a lenticular lens placed in the ...
