The Application Of Thin Film In The LCOS Optical System

LCOS display is the organic integration of LCD and CMOS integrated circuit the reflection of a new display technology. LCOS as a new large-screen display, high-intensity, high-resolution, energy saving, and many other advantages, its applications are many preferences. LCOS may be a rear projection HDTV technology development the main direction. In large-screen projection display has an important position, as the economic and light, it became the big-screen projection technology CRT TV's main competitors. And the transmission HTPS-LCD and DLP comparison, LCOS has the following advantages: a high-efficiency, small size, high resolution, mature manufacturing technology.In recent years, LCOS display technology and the rapid development of industrialization and greatly promote the development of the optical films, but also to optical films made higher requirements. LCOS display technology papers for the requirements of the system of optical films for an in-depth study and discussion. Paper, include the following aspects:Chapterâ… briefly introduced the optical film history and development of LCOS display technology and the development of the status quo. First of optical films, optical thin film technology and optical design technology of film history and development of the status quo was on, and then discussed in detail LCOS display technology and the advantages of the problems faced.Chapter II we reviewed the design of the optical film theoretical basis. Starting from Maxwell's equations, a single plane on the fundamental nature of electromagnetic waves, as the basis for discussion of the optical films of theoretical calculations and analysis methods, LCOS optical system for optical film laid the foundation for the design.Chapterâ…¢of our in-depth analysis of the LCOS optical system used in the optical thin film systems, and completed the design of various types of film terms. LCOS film system for the optical system is a complex, high-precision, a wide variety of films. It includes: edge filters used in color spectroscope, polarizing beam films used in polarizing beam mirror, cold light film used in lighting system. There is also broadband antireflection coating, various wave band antireflection coating and high-reflection film. We use Mass design software to complete the design of a variety of films, the performance was excellent, with good technology to meet the design requirements of the fine structure of films. In chapter IV we mainly discussed on the preparation of the film. In optical films, as long as the characteristics of a reasonable request, the total can be designed to fit the multi-layer structure. The key problem lies in the actual preparation of multi-layer film, which involves the design of error tolerance of the membrane structures; choose a suitable film material and preparation process; precise control of all levels of film thickness and refractive index, is expected to be the optical and mechanical characteristics. In order to verify the design of the performance of films, the large amount of the experimental study. In the actual preparation, since the equipment and time constraints, only a representative of a number of films, such as broadband antireflection coatings, high-reflection film and edge filters, and detected by the plating of the film, was a more good result.In the chapter V we give a brief summary of the full text, the next step and the work of the future.
