Problems solved by technology

Byoungho Lee et al. have long proposed a method to dynamically change the distance between the microlens array and the display to improve the depth of field. However, it is difficult to change the object distance by moving the microlens array at high speed, and the system stability is poor.

Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] As a further scheme of the present invention: the concrete operation of step 4 is: select the NOA89 that viscosity is 15-20cps, select the needle head of 80 μm of Jetlab2 ink-jet printing equipment, then search reference point, and Jetlab2 air pressure debugging is when-12Pa when liquid and After the nozzle surface is flush, a half crescent appears, and then adjust the system parameters to obtain stable droplets without satellite droplets. The volume of ...

Abstract

The invention discloses a double-layer pinhole microlens combination array manufacturing method based on inkjet printing. The invention provides high-precision and high-aligning-degree precision of the integrated imaging double-layer pinhole / microlens combination array through lithography and inkjet printing. The method comprises the steps of preparing a black circular hole trough array (namely acircular hole array) by means of a lithography method, performing fixation by means of black circular holes; then performing inkjet printing on a cleaned black circular hole array through using UV resin with low viscosity and high transmittance as ink, forming a projected ink liquid drop by means of a hydrophobic effect of a template and an interface tension function of a substrate, regulating a liquid drop parameter through controlling a printing air pressure and a driving voltage, performing multiple times of printing under a precondition that no decorative modification on the substrate surface is not required, regulating a lens height; and obtaining a high-quality microlens array after ultraviolet curing.

Description

technical field [0001] The invention relates to the technical field of 3D imaging, in particular to a method for manufacturing a double-layer pinhole microlens combination array based on inkjet printing. Background technique [0002] The advent of holographic display technology has brought hope to true stereoscopic 3D TV. Compared with stereoscopic television, the advantage of holographic television is not only that the stereoscopic three-dimensional image is closer to the object itself, but also consider the physiological psychological suggestion of the human eye to the depth perception of the object. [0003] According to the principle of lens imaging, the focal length of the lens and the object distance determine the size of the image distance, that is, determine the position of the depth of center plane (CDP) of the integrated imaging. Each CDP has a certain depth of field range, and the position of the CDP can be changed by adjusting the distance between the reconstruc...
