Scrolling multi-stripe color illumination system

Single panel scrolling color projection systems using three (red, blue and green) scrolling color stripes have been demonstrated to be adequate for television images. However, computer graphics displays are more prone to color artifacts. The invention increases the number of scrolling color stripes in order to suppress these artifacts. One implementation is to break up the three color stripes into multiple bands using a lenticular lens array, and then to collimate the multiple stripes with a second lens array. The collimated stripes are scrolled using the rotating prism of the prior systems.

UV-LED glass ink and preparation method and use method thereof

ActiveCN109181405AGood flexibilityLow film shrinkageInksChemistryPhotoinitiator
The invention discloses a UV-LED glass ink and a preparation method thereof. The glass ink is prepared by the steps: taking polyester acrylate, difunctional polyurethane acrylate and hexafunctional polyurethane acrylate as main raw materials, adding an active monomer, a filling agent, a photoinitiator, an auxiliary agent and silicon dioxide, and evenly mixing the raw materials and grinding to prepare the glass ink. The glass ink has the characteristics of fast curing speed and high curing efficiency. By adjustment of the composition of the filling agent, the glass ink with different appearanceeffects can be prepared. The invention also provides a use method for the UV-LED glass ink; 250-300 mesh screen printing is adopted, the thickness of an ink layer is controlled to 10-30 [mu]m, and photo-curing is carried out for 40-60 s after printing is completed. The glass ink has short curing time and good curing effect, cannot make glass products yellowed, and does not cause damage to operator bodies due to too strong light illumination in the curing process.

Method for producing luminous organic glass embedded handicraft

The invention discloses a method for producing a luminous organic glass embedded handicraft. The method comprises the following steps of: adding an initiator into a methyl methacrylate monomer, and heating and reacting to obtain prepolymerization slurry; adding luminous powder, an antisettling agent and a defoaming agent into 1/3 to 2/3 of prepolymerization slurry, and casting the mixture into a mould for polymerization until slurry in the mould is in a solidification state; sequentially embedding an insert and casting the residual prepolymerization slurry, and polymerizing at the temperatures which are sequentially varied from high to low and are in gradient distribution; and finally, polymerizing at the temperature of 100 and 120 DEG C, demoulding, grinding, and polishing to obtain the luminous organic glass embedded handicraft. The luminous organic glass embedded handicraft produced by the method has the advantages that: one-time polymerization production time can be controlled to be between 4 and 6 hours; a luminous bottom layer has different colors and uniform luminescence; no bubble exists in an intermediate layer of the insert, and original appearances of various animal and plant specimens, pebbles, photos and billboards are maintained; and an upper transparent layer is high in transparency.

Method of making a porous tio2 photonic film

A porous titanium dioxide film having photonic properties is made by etching a titanium substrate in an electrolyte solution in the presence of an electric field. The electrolyte solution can be an organic electrolyte solution. Etching involves providing an electrolyte solution in contact with a pair of electrodes and passing an electric current through the electrolyte solution. The titanium substrate can be one of the pair of electrodes. The current has a wave profile selected from a group consisting of a periodic square profile, a sine wave, a linear profile, or a quintic profile, and is provided either parallel of perpendicular to a plane of the substrate.
