Description

3D display and its manufacturing method

technical field

This case belongs to the field of 3D display devices, and in particular relates to a manufacturing method of a 3D display and a grating device thereof.

Background technique

The principle of the well-known stereoscopic image display technology is to use binocular disparity (Binocular disparity) to receive different images through the left and right eyes, and finally fuse them into a stereoscopic image in the brain. In the naked-eye 3D display technology, there are three common types of light barrier (Barrier), lenticular lens (Lenticular Lens) technology and directional light source (Directional Backlight). The above three structures have their own advantages and disadvantages. Among them, the lenticular lens is composed of many slender straight convex lenses arranged continuously along the direction of one axis, and uses the principle of optical refraction to produce different views of the left and right eyes, which is also called a grating structure. Compared with the light barrier structure, the refraction of light is used to achieve the purpose of splitting light, so there is no loss of light and good brightness, but there are refraction restrictions at the edge of the lens structure, which makes the refraction effect poor, or due to the columnar structure The error of the lens, the lens surface is not easy to be flat and other factors, there will be stray light, resulting in a partially blurred three-dimensional image, which affects the display effect of the overall 3D image; Light from some angles is emitted, and only certain angles of view images are transmitted to the left and right eyes to generate a stereoscopic image. Compared with the lenticular lens, the monocular image is clearer, but its inherent structural characteristics will reduce the brightness of the overall image , image resolution degradation and other defects.

In addition, such as the "Display Device for Switching 2D Planar Image/3D Stereoscopic Image Display Screen" of Taiwan Utility Model Patent No. M371902, it includes a flat-panel display and a parallax barrier panel arranged on a display surface of the flat-panel display, wherein the The parallax barrier panel includes a barrier pattern, which includes a first electrochromic material layer and a second electrochromic material layer, and in a 2D plane image display state, the barrier pattern, the first electrochromic material layer and the second electrochromic material layer The two electrochromic material layers are both transparent, and in a 3D stereoscopic image display state, the fence pattern is an opaque pattern, and the first electrochromic material layer has a first color, and the second electrochromic material layer has a second color. Also, as in the Taiwan Patent Gazette of China, the "Display Device for Switching 2D Plane Image/3D Stereoscopic Image Display Screen" of the announcement No. M368088 is a structure in which a parallax barrier unit is embedded in a liquid crystal display substrate, which includes: a first Substrate; a parallax barrier unit is arranged under the first substrate; a color filter unit is arranged under the parallax barrier unit; a common electrode is arranged under the color filter unit; a liquid crystal unit is arranged under the common electrode; A thin film transistor is arranged under the liquid crystal unit; a second substrate is arranged under the plurality of thin film transistors; and a light source is arranged under the second substrate; To reduce the thickness and assembly cost of the known display device, however, the barrier pattern of the parallax barrier unit places a transparent conductive layer and an electrochromic layer in a barrier-shaped groove of an insulating transparent material, although it can reduce the liquid crystal of the three-dimensional image The thickness of the display still has considerable complexity in the actual manufacturing process.

The above patents all use electrochromism (Electrochromism, EC), which means that under the action of current or electric field, the electrochromism material undergoes light absorption or light scattering, resulting in a reversible reaction of color oxidation or reduction, but the above patents The electrochromic device lacks the necessary electrolyte layer, so that the electrochromic device will not be able to produce a reversible reaction to complete the coloring or decolorization change, or its coloring and decolorization speed is very slow. In addition, the transparent electrode layer and the electrochromic material layer of the parallax barrier device are all arranged in a fence pattern, and the layered coating, sputtering or etching in the manufacturing process, as well as the accurate alignment of each stacked layer, will cause The complexity of the manufacturing process is increased, resulting in poor manufacturing efficiency.

In addition, the above-mentioned patents all use known solid-state electrochromic materials, whose coloring/fading speed is relatively slow and the driving voltage is high. If the reaction speed is fast and the driving voltage is small. Therefore, liquid solution-type electrochromic materials are also used instead. However, liquid solution-type electrochromic materials are not plated on the surface of a conductive substrate in the form of a fence-like structure. A barrier fence is set on the substrate for filling the solution-type electrochromic material. When the solution-type electrochromic material changes color, the shielded part is in a light-transmitting state. The invention provides a 3D display and the manufacture of a grating device According to the method, the barrier fence can be manufactured in one process and the solution-type electrochromic material has been packaged in the device, thereby simplifying the manufacturing and greatly improving the manufacturing efficiency.
