The invention relates to a color-adjustable kneading molding material micro-sculpture three-dimensional pixel picture and a production method thereof. The color-adjustable kneading molding material micro-sculpture three-dimensional pixel picture mainly comprises three-dimensional pixels having the same color as the pixels in the whole picture, and is characterized in that the three-dimensional pixels are micro-sculptures formed through imprinting molding with molds, the micro-sculptures comprise color-adjustable kneading molding materials, each micro-sculpture can comprises a single-color kneading molding material and is corresponding to the one pixel in the whole picture, and the micro-sculptures can comprise multi-color kneading molding materials and are corresponding to a plurality of pixels in the whole picture. According to the present invention, each three-dimensional pixel entity in the three-dimensional pixel picture of the present invention has rich color representability and rich shape modeling.

A sand painting platform device based on a projector and capable of adjusting colors comprises the projector (1), a reflection system (2), a diffuser screen (3), a sand painting workbench (4), a control panel (5), a camera system (6) and a displayer (7). Color light rays projected by the projector (1) are diffused after being reflected onto the diffuser screen (3) through the reflection system (2) and then are emitted upwards. The emitted light rays are blocked by sand on the sand painting workbench (4) and thereby present sand painting works on the sand painting workbench (4). A designer can change the light rays emitted from the projector (1) through the control panel (5), accordingly brightness and the colors in different areas on the sand painting workbench (4) are changed, and the sand painting works in different colors are presented. Meanwhile, the camera system (6) shoots the painting process and the works so as to enable the painting process and the works to be displayed on the displayer (7) for appreciation of audience. The sand painting device enables the sand painting works to present different colors, brings great convenience for the designer and brings visual experience of high art value for the audience.

The invention relates to a method for preparing a butterfly wing / colloid crystal microsphere composite structural color film by a vertical deposition method, and belongs to the technical field of structural color film preparation. The butterfly wing with periodic structure was selected as a template, and the surface of the butterfly wing was pretreated; the colloidal crystal microsphere dispersion liquid was prepared and ultrasonically dispersed to make it in a uniformly dispersed state; after the butterfly wing was cut, it was placed vertically In the petri dish, slowly add the microsphere dispersion to completely submerge the butterfly wings, then place the petri dish in a constant temperature and humidity box, and assemble it by vertical deposition method. After the solvent is completely evaporated, butterfly wings / colloidal crystals are obtained The microsphere composite structure achieves specific color rendering effects in different viewing directions. The invention also discloses a batch preparation method of the film. The invention can realize structural color display with wide color gamut, narrow band gap, high brightness and special color rendering effect, and not only has important scientific research value, but also has great application value.

The invention discloses a light emitting diode (LED) luminous device. The LED luminous device comprises a purple-light LED chip, a blue-light LED chip and a fluorescent adhesive, wherein the fluorescent adhesive covers the purple-light LED chip and the blue-light LED chip and comprises nitrogen oxide green fluorescent powder, green fluorescent powder with half-wave width below 40 nanometers, Mn<4+> activated fluoride red fluorescent powder and silica gel, and the mass percent of the weight of the nitrogen oxide green fluorescent powder in the total weight of the nitrogen oxide green fluorescent powder, the green fluorescent powder with half-wave width below 40 nanometers and the Mn<4+> activated fluoride red fluorescent powder is less than or equal to 25%. The invention also discloses a backlight module employing the LED luminous device. By the LED luminous device, high color gamut can be acquired, mass production also can be achieved, and the reliability is high. When the LED luminous is applied to the backlight module, a fabricated LED television is approximate to a quantum dot (QD) television in national television system committee (NTSC) gamut, and audience acquires favorable visual experience.

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.

The invention relates to the field of ink, and provides an ink with metallic luster. In terms of weight percentage, the preparation raw materials at least include: 10-30% of dye, 5-25% of auxiliary agent, 5-20% of gold powder, and the balance of water.

A sand painting device based on a liquid crystal displayer and capable of adjusting colors comprises a first displayer (1), a sand painting workbench (2), a control panel (3), a camera system (4) and a second displayer (5). The first displayer (1) is located below the sand painting workbench (2), displays color images, and casts color light rays towards the sand painting workbench (2), and the color light rays are blocked by sand on the sand painting workbench (2), so that sand painting works in different colors are presented on the sand painting workbench (2). A user can change emergent light rays of the first displayer (1) through the control panel (3) so that brightness and colors in different areas on the sand painting workbench (2) can be adjusted, and the sand painting works in different colors are achieved. Meanwhile, the camera system (4) shoots the painting process and the works so as to enable the painting process and the works to be displayed on the second displayer (5) for appreciation of audience. The sand painting device enables the sand painting works to present different colors, brings great convenience for a designer and brings visual experience of high art value for the audience.
