Optical image amplification device and image display system

Abstract

The invention belongs to the field of optical image amplification, and particularly relates to an optical image amplification device. The optical image amplification device comprises an eccentric microlens array arranged on a display device; the caliber size of each eccentric microlens in the eccentric microlens array is consistent to the size of one or more pixels of the display device; or the caliber of the plurality of microlenses is consistent to the size of one pixel, and the central position of each eccentric microlens is consistent to the central position of one or more pixels of the display device; or the central position of the plurality of microlenses is consistent to the central position of one pixel of the display device. By adopting the device, the large-area optical image can be amplified, and furthermore, the definition of the amplified image and the thinning of the display device can be ensured. Furthermore, the invention also discloses an image display system with the optical image amplification device.

Description

technical field [0001] The invention belongs to the field of optical image enlargement, in particular to an optical image enlargement device and an image display system with the device. Background technique [0002] How to optically magnify a large-area display image has become a research hotspot. The general optical image magnification method is to use an optical lens to magnify the image. There is a certain distance between the optical image and the lens, and the aperture of the optical lens is much larger than the optical image. For a large-area optical image, using this conventional method for optical amplification is not conducive to the thinning of the display device. Although it is more feasible to use a Fresnel lens to magnify a large-area optical image, it has relatively high requirements for the image display device, requiring the light emitted by the image display device to be collimated light, otherwise there will be overlap between pixels Stray, it is difficul...

For large-area optical images, using this conventional method for optical amplification is not conducive to the thinning and lightening of display devices

Although it is more feasible to use a Fresnel lens to magnify a large-area optical image, it has relatively high requirements for the image display device, requiring the light emitted by the image display device to be collimated light, otherwise there will be overlap between pixels Stray, it is difficult to ensure the clarity of the enlarged image
