Objective
LSVI is a low-cost, high-performance, large-size full-colour visual interface based on the rear projection of three monochromatic images, formed on the screens of CRTs by a novel lens system, onto a viewing screen. This lens system has a significantly reduced number of elements. This approach enables the visual interface to cope with sizes up to 0.5 m{2} (A1), featuring full-colour, high-resolution, high brightness projected images with good contrast. The multiscanning format capability makes possible a wide range of applications where the visual presentation of data is important (eg graphics and 3-D presentation of information).
Large size visual interface design for multimedia workstation terminals (LSVI) is a low cost, high performance, large size full colour visual interface based on the rear projection of 3 monochromatic images, formed on the screens of cathode ray tubes (CRT) by a novel lens system, onto a viewing screen. This lens system has a significantly reduced number of elements. This approach enables the visual interface to cope with sizes up to 0.5 m{2} (A1), featuring full colour, high resolution, high brightness projected images with good contrast. The multiscanning format capability makes possible a wide range of applications where the visual presentation of data is important (eg graphics and 3-dimensional presentation of information).
The main goal of the LSVI project is to demonstrate the visual interface through advanced developments in electronics, CRT technology and projection optics.
The first results of the work carried out are:
processor controlled digital correction of convergence and geometry distortion;
multiscanning format capability;
samples of CRTs with improved phosphor screening technology and higher resolution;
design of a single lens projector with internal beam combiner;
examination of current triple lens systems which has led to the design of a novel triple lens system with greatly reduced cost and number of components.
The LSVI project will contribute to and have an impact on the visualisation of computer-generated data. It is based on European technology and will conform to existing standards, as well as contributing to the development of new international standards.
The main goal of the LSVI project is to demonstrate the visual interface through advanced developments in:
- Electronics: processing of broadband video signals at high voltage; deflection circuits at high deflection frequencies to meet resolution requirements and reduce power consumption; stable digital correction of convergence and geometry distortion; and multiscanning format capability.
- CRT technology: improvements in the overall luminous efficiency of the screen; interfacing faceplate cooling facilities with projection optic devices; and shorter, high current and enhanced resolution electronic optics design.
- Projection optics: optimisation of the CRT/optics interface; reduced trapezoidal distortion; design of compact magnifiers; shortening the optical path; and design of a viewing screen with good optical gain.
