Problems solved by technology

That is to say, it is difficult to prepare color images with pixel units smaller than 5 microns using existing technologies
Moreover, the above-mentioned color image and its coloring method all directly dye the pixel unit, and this coloring method limits the improvement of image resolution and also limits the image effect.

Embodiment 1

[0047] This embodiment provides a thin-film color image under scattered light illumination, as shown in the attached figure 1 to attach figure 2 As shown, the color image 8 includes a focusing element array layer 1 , a first dyed layer 2 , a substrate layer 3 , a micropattern array layer 4 and a second dyed layer 5 bonded in sequence. The focusing element array is formed by orthogonal arrangement of spherical microlens units with square apertures. The first dyed layer 2 is composed of transmissive red, green and blue three-color pigments arranged in an orthogonal array of pixel lattices. A pixel point of one color on the first dyed layer 2 corresponds to one spherical microlens unit. The micro-pattern array layer 4 is formed by arranging orthogonally arranged groove-type micro-pattern units on the lower surface of the substrate layer 3, and the pixel size of the micro-pattern units is 10 microns. The second dyed layer 5 is filled with white pigments in the grooves of the g...

Embodiment 2

[0051] This embodiment provides a thin-film color image under scattered light illumination, as shown in the attached image 3 As shown, the color image 8 includes a focusing element array layer 1 , a first dyed layer 2 , a substrate layer 3 , a micropattern array layer 4 and a second dyed layer 5 bonded in sequence. The focusing element array is formed by a honeycomb arrangement of spherical microlens units with a hexagonal aperture.

[0052] Specifically, the first dyed layer 2 is formed by a honeycomb arrangement of color pixel lattices composed of transmissive red, green and blue pigments. The color pixels of two colors on the first dyed layer 2 correspond to one microlens unit to form richer colors. The micro-pattern array layer 4 is formed by setting honeycomb-arranged groove-type micro-pattern units on the lower surface of the substrate layer, and the pixel size of the micro-pattern units is 4 microns. The second dyed layer 5 is filled with white pigments in the groove...

Embodiment 3

[0055] This embodiment provides a thin-film color image under scattered light illumination, as shown in the attached Figure 4 As shown, the color image 8 includes a focusing element array layer 1 , a first dyed layer 2 , a substrate layer 3 , a micropattern array layer 4 and a second dyed layer 5 bonded in sequence.

[0056] Preferably, the array of focusing elements is formed by orthogonal arrangement of aspherical microlens units with circular apertures.

[0057] Preferably, the first dyed layer 2 is formed by an orthogonal arrangement of color pixel lattices composed of transmissive red, green and blue pigments. A color pixel point of one color on the first dyed layer 2 corresponds to one microlens unit. The color pixels corresponding to the different microlens units have different sizes, and the saturation of the corresponding color can be adjusted by adjusting the size of the color pixels.

[0058] Further, the micro-pattern array layer 4 is formed by arranging orthogo...

Abstract

The invention relates to the field of dyeing and color images, in particular to a color image, which comprises a focusing element array layer, a first dyeing layer, a base material layer, a micrographic array layer and a second dyeing layer arranged in sequence, and each layer is adhered to each other. forming a film-type color image; the focusing element array layer is composed of a focusing element array formed by focusing units, the first dyed layer is formed by a color pixel dot matrix, and the micro-pattern array layer is composed of micro-pattern units The array of arranged micro graphics is formed, and the second dyed layer is formed by an array of colored pixels. The color image of the present invention adopts indirect dyeing of two dyeing layers, can realize the color image with the pixel unit smaller than 5 microns, improves the resolution of the color image, enriches the color of the color image, and improves the display effect of the color image. The formed color image has novel effects such as color three-dimensional, dynamic, light change, light response, etc., and has wide application prospects.

Description

technical field [0001] The invention relates to the field of dyeing and color images, in particular to a color image, which can be used in the fields of color printing, three-dimensional display, anti-counterfeiting security and the like. Background technique [0002] Compared with black and white or monochrome images, color images have richer information and are more in line with the natural observation needs of human eyes. Display, printing, copying, printing and other technologies have all experienced the development process from black and white image output to color image output. Among them, display resolution is an important technical indicator to measure the quality of color images. High-resolution, high-quality color images have always been the goal pursued by people. At present, in the field of dynamic display, the size of a single pixel unit of an ultra-high-definition LCD screen is about 10 microns; in the field of printing and copying, the resolution of graphics...
