In particular, it is related to a light-guiding array structure with a microlens system. [Previous technology] In today's life, some video display technologies are often used, especially for display devices of portable electronic devices with low power consumption. Liquid crystal display (LC) is one of the main technologies applied to these display devices, which requires an external light source to present an image. However, these portable electronic devices usually use batteries as their sole source of power. In consideration of power saving, how to improve the light utilization efficiency becomes very important. Therefore, 'There are many technologies for improving the efficiency of light irradiation applied to liquid crystal display devices. The above-mentioned technologies are not only applied to portable electronic devices, but also widely used in image projection, which are mainly divided into]) MD ( Digital Mirror Device) projection and LCD projection.

Creation instructions (2) Confrontation: Display devices with less stringent requirements (such as monitors for laptops or shirt projectors) require higher light irradiation efficiency, but due to The function of the diffusion sheet: The directivity of the emitted light is very poor, so an additional light-concentrating junction needs to be added to improve the light irradiation efficiency. As shown in the first figure, the 'showing light 142' is generated by the cold cathode ray tube 14. When the light enters the light guide plate 12 from the end surface, most of the light 142 will be transmitted to the thin end by total reflection. When the light 1 42 hits the diffusion point on the bottom surface, the reflected light will diffuse at various angles, so that the part of the reflected light will destroy the total reflection condition and is emitted from the front of the light guide plate 12, from "Γ and 2ΐ :: 出 光 142 It will be diffused by the diffuser plate 16. Adding a prism 4 lens that has a light-concentrating effect on the diffuser plate ρ can increase the directivity of the light and improve the brightness of the front side. When a rectangular array of ridges is used, the front side can be made approximately. The brightness is improved by 6 households. If the two-mirror array is used, the brightness of the I side can be changed by approximately twice as much as the front brightness. The condensing effect of the array makes the new type of t-light irradiation efficiency. The purpose is to improve the holographic array with a micro lens system. Another new purpose of the new type is to provide a transparent material shape to cover the gap of the micro lens array without expanding the irradiation efficiency of the incident light in the gap of the film being described.

The micro lens system has predetermined physical characteristics and optical characteristics to control the incidence of light from the 入射 array. The path on the micro-lens system provides a light field, so that the micro-lens system 22 and the chirped array 24 form a light-guiding screen with light-guiding properties. 〃 In addition, the cymbal array 24 may be a corner-cylindrical cymbal array 24 or a corner-parameter cone-shaped cymbal array 25, as shown in the second D and second E diagrams. In addition, the above-mentioned holmium array may be composed of two orthogonal holmium arrays 2 4 and 稜鏡 arrays 2 5 and a microlens system 22 respectively, as shown in the second f diagram. Generally, there is a gap in the arrangement of the micro lens array. This is due to the consideration of the difficulty in the manufacturing process, so that the incident light in the gap portion is not easy to use. The new type is coated with a layer of light-transmitting material on the micro-lens array to enlarge the shape of the micro-lens to expand the gap, thereby improving the lighting performance of the light.

For example, the light era: The arrangement of the micro-lenses 322 is too neat, which makes the audience feel that some areas are particularly bright and the areas are very dark due to the m-ray phenomenon. For example, the bottom of each microlens 322 is a member selected from one of the following groups: a two-cornered wide rectangle, a polygon, a circle, an oval, a fan, or any other geometric figure. Furthermore, the micro-lens system 32 may be a plano-convex micro-lens system, a plano-concave micro-lens system, a convex-convex micro-lens system, a convex-concave micro-lens system, or a concave-concave micro-lens system.
