Embodiment Construction

[0036] Please refer to Figure 1 to Figure 3 , Figure 1 to Figure 3 It is a schematic diagram of the manufacturing method of the optical component of the first embodiment of the present invention, wherein image 3 It is a three-dimensional schematic view of the optical assembly of the first embodiment of the present invention. Such as figure 1 As shown, a first transparent substrate 102 such as glass, acrylic or quartz is firstly provided. Then, a first lithography process is performed to form a first photoresist pattern layer 104 on a surface of the first transparent substrate 102, and the first photoresist pattern layer 104 exposes part of the first transparent substrate 102, wherein the first The pattern of a photoresist pattern layer 104 is the same as the top view pattern of the optical component to be formed. In this embodiment, the pattern of the first photoresist pattern layer 104 is a plurality of rectangular blocks arranged along a first direction 108 , but it is...

Abstract

The invention discloses a display device, an optical assembly, and a production method of an optical assembly. The optical assembly comprises a transparent substrate, a plurality of transparent cuboid structures, and filling medium. The transparent cuboid structures are disposed on the transparent substrate. The top surface of each of the transparent cuboid structures is parallel to the surface of each of the transparent substrates, and the side surfaces are parallel to each other. At least parts of the transparent cuboid structures are arranged along the direction vertical to the direction of the side surfaces, and the two adjacent transparent cuboid structure are provided with a gap, which is filled with the filling medium. The refractive index of the filling medium is smaller than the refractive index of each of the first transparent cuboid structures.

Description

technical field [0001] The present invention relates to a display device, its optical component and its manufacturing method, in particular to a floating image display device with multiple non-contact transparent cuboid structures, its optical component and its manufacturing method . Background technique [0002] The existing floating image display device is composed of an object and an optical component. In addition, the optical component can slightly reflect the light beam, so that the image of the object disposed on one side of the optical component can be mirror-imaged on the other side of the optical component through the reflection of the optical component. In this way, the image of the object can be displayed on the other side of the optical assembly. [0003] Currently, the optical assembly disclosed in U.S. Patent Publication No. 20110181949 is composed of a plurality of strip-shaped micro-mirror units stacked side by side, and each micro-mirror unit consists of a...
