Display assembly for three-dimensional display device 【0001】

The present invention relates to a display assembly for a three-dimensional display device; more specifically, the display assembly of the present invention for a three-dimensional display device is optimized in proportion.

【0002】

In the conventional display device, if one wants to present three-dimensional vision, one of the common techniques is Parallax Barriers, which is mainly provided with a small straight fence on the screen to block the screen light, and the user's eyes are You can view different images due to the effect of light shielding and parallax to produce a three-dimensional visual effect. However, since this method will reduce the visible light of the left and right eyes by half, the brightness of the screen perceived by the user will be greatly reduced.

[0003]

Accordingly, the Lenticular Lens has been developed, mainly by providing a convex lens in front of the pixel and using the effect of the convex lens to refract light to generate parallax, so that the user's eyes can view different images accordingly. Produces a three-dimensional visual effect. Since the light is not blocked by the convex lens, the brightness of the screen perceived by the user is not affected.

[0004]

However, since the size and quality of the columnar lens are currently different, and the positional relationship between the lens and the pixel to be covered is not adjusted accordingly, even if the use of the columnar lens allows the user to view the picture. The brightness is not affected, but there is still considerable room for improvement in the comfort of the user's viewing.

[0005]

In summary, how to improve the shortcomings of the conventional cylindrical lens, so that the user can view the three-dimensional visual effect more comfortably, is an urgent need for the industry.

[0006]

The main object of the present invention is to provide a display assembly for a three-dimensional display device comprising a lens layer and a pixel layer. The lens layer includes a plurality of columnar convex lens units and a lens substrate. The thickest portion of each of the columnar convex lens units is 8 μm and the radius of curvature is 0.841 mm. The thickness of the lens substrate is 128 microns. The pixel layer contains a plurality of pixels, and these pixels form a sub-pixel matrix. The lens layer is disposed corresponding to the pixel layer, and the lens substrate is interposed between the plurality of columnar convex lens units and the pixel layer and spaced apart from the pixel layer by 40 micrometers. Each of the columnar convex lens units respectively corresponds to two rows/four rows of pixels of the sub-pixel matrix, and is used to respectively refract the light sources of the two rows/four rows of sub-pixels of the sub-pixel matrix to the second/fourth direction.
