Problems solved by technology

[0003] The traditional grating is generally made by carving a large number of parallel notches on the glass sheet, and the light is transmitted through the smooth part between the two notches. The traditional grating does not make one side of the base film protrude to form a cylindrical lens structure through temperature control. , and can not cause chromatic aberration in the base film, so that there is parallax between the images observed by the left and right eyes. The bulge of the film changes regularly, it is difficult to make the depth of the image clearer, and the practicability is not strong

Embodiment Construction

[0028] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.

[0029] Such as figure 1 , figure 2 with image 3 As shown, a temperature-controlled grating film includes: a base film 1 and a resistance wire 2; a number of resistance wires 2 are arranged inside the base film 1, and the two ends of the resistance wire 2 are respectively connected to a positive electrode line row 3 and a negative electrode line row 6 , when the two ends of the resistance wire 2 are connected to the power supply, the resistance wire 2 generates heat, so that a protrusion 7 is formed on one side of the base film 1, and the base film 1 is raised by 7 degrees by adjusting the voltage of the resistance wire 2, so that the base ...

Abstract

The invention relates to a temperature-controlled optical grating film. The temperature-controlled optical grating film comprises a base film and resistance wires; the plurality of resistance wires are arranged in the base film; two ends of each resistance wire are respectively connected with a positive pole terminal and a negative pole terminal; when the two ends of each of the resistance wires are connected with a power source, the resistance wires generates heat, so that protrusions are formed at one side of the base film; the voltages of the resistance wires can be changed, so that the protrusion degree of the base film can be changed, and therefore, the refractive indexes of each point of the base film layer are different, and a lenticular grating layer is formed; and light passes through the grating layer so as to form a stereoscopic image.

Description

technical field [0001] The invention relates to a grating film, in particular to a temperature-controlled grating film. Background technique [0002] An optical device consisting of a large number of parallel slits of equal width and equal spacing is called a grating. The grating is a sheet composed of strip lenses. When we look from one side of the lens, we will see an image on a very thin line on the other side of the sheet, and the position of this line is determined by the viewing angle. It is decided that if we print these images on different lines, corresponding to the width of each lens, on the back of the grating sheet in order, when we observe through the lens from different angles, we will see different images. image. [0003] The traditional grating is generally made by carving a large number of parallel notches on the glass sheet, and the light is transmitted through the smooth part between the two notches. The traditional grating does not make one side of the ...
