Problems solved by technology

The microlens produced by this method has high precision, but the microlens produced by each printing can only be a few square centimeters in size, the production speed is slow, and the production cost is high. It can only be applied to electronic and electrical components with high precision requirements. Narrow, difficult to achieve mass use

Embodiment 1

[0036] Step 1: Make the grid frame: select 200-mesh mesh yarn and fix it on the screen frame to make a grid frame;

[0037] Step 2: Screen making: First, use a mesh scraper to coat a photosensitive emulsion on the grid to prepare a photosensitive film layer, then dry it with a dryer, repeat the above steps until the photosensitive film layer is 140 μm thick, and the thickness of the photosensitive film layer must be Uniform;

[0038] Step 3: Exposure and washing: Cover the film positive film with the development pattern on the photosensitive film layer, and then expose for 5 minutes. After the exposure is completed, the screen plate is rinsed with water, and the screen will appear on the screen that matches the film positive film. ;

[0039] Step 4: Printing: Select the base material 1, after the screen plate exposed in step 3 is dry, cover the screen plate on the base material 1, and apply transparent UV ink on the screen plate with a scraper, and the UV ink will pass throug...

Embodiment 2

[0043] Step 1: Make the grid frame: select 225-mesh mesh and fix it on the screen frame to make a grid frame;

[0044] Step 2: Screen making: First, use a mesh scraper to coat a photosensitive emulsion on the grid frame to prepare a photosensitive film layer, then dry it with a dryer, repeat the above steps until the photosensitive film layer is 135 μm thick, and the thickness of the photosensitive film layer must be Uniform;

[0045] Step 3: Exposure and washing: Cover the film positive film with the development pattern on the photosensitive film layer, and then expose for 5 minutes. After the exposure is completed, the screen plate is rinsed with water, and the screen will appear on the screen that matches the film positive film. ;

Embodiment 3

[0050] Step 1: Make the grid frame: select 250-mesh mesh and fix it on the screen frame to make a grid frame;

[0051] Step 2: Screen making: First, use a mesh scraper to coat a photosensitive emulsion on the grid frame to prepare a photosensitive film layer, then dry it with a dryer, repeat the above steps until the photosensitive film layer is 115 μm thick, and the thickness of the photosensitive film layer must be Uniform;

[0052] Step 3: Exposure and washing: Cover the film with a developing pattern on the photosensitive film layer, and then expose for 7 minutes. After the exposure is completed, the screen is rinsed with water, and the screen will appear on the screen that matches the film. ;

[0053] Step 4: Printing: Select the base material 1, after the screen plate exposed in step 3 is dry, cover the screen plate on the base material 1, and apply transparent UV ink on the screen plate with a scraper, and the UV ink will pass through The mesh adheres to the substrate...

Abstract

The invention relates to manufacturing technology of a micro-lens, and in particular relates to a process for preparing a micro-lens crystal and application of the micro-lens crystal. The process for preparing the micro-lens crystal comprises the following steps of: 1, preparing a screen rack; 2, preparing a halftone; 3, exposing and developing; 4, printing; and 5, printing down. The preparation process has the characteristics of one-time production of larger-area micro-lens layout, improvement on production efficiency and reduction in production cost. The prepared micro-lens crystal is widely applied to three-dimensional printing, material packaging, light source amplification and the like, and is suitable for the mass-market demand.

Description

technical field [0001] The invention relates to screen printing technology, in particular to a microlens crystal and a preparation process thereof. Background technique [0002] A lens is a very familiar optical component, which belongs to the passive optical component and is used to converge and diverge light radiation in an optical system. The usual lenses are relatively large in size and can be seen by the human eye. They are refractive optical elements and follow the law of refraction. Their optical properties can be well studied with the knowledge of geometric optics. The same lenses are arranged on a plane at a certain period to form a lens array. The optical properties of a lens array composed of ordinary lenses are the synthesis of the functions of a single lens. [0003] However, with the advancement of science and technology, current instruments and equipment have developed towards the trend of optical, mechanical and electrical integration. Optical components m...
