Essential Requirement For Safety And Performance On Laser Displays Projector

Display technology has experienced three generation, including a monochrome display, color display, and digital display; and now the fourth generation display technology-large color gamut display is booming. Because of the influence of the manufacturing cost reducing and convenient use, projection display is spreading and playing an increasingly important role in various fields. Following the quality of life improved, the projector performance is becoming more and more important, which also caused the test of projector performance become indispensable step in the production.As the next generation of full-color display technology, laser projection display technology has many obvious advantages. Laser projector display industry will enter a period of rapid growth, and market maybe up to$57000000000a year in industry-scale.Any product need to test before approaching market. Laser projector also needs some indicators to confirm whether they are qualified product, and product standardization is to ensure that the products shall meet the requirements of the applicable standards.However there are no specific national laser projector standards, so it is necessary to establish a scientific, accurate, concise, unity, practical standard. Refer ing the user’s intentions and the enterprise product structure, the formulated standard can provide security and technical index of evaluation of the laser projector production. Meanwhile the standard provides excellent and reliable security products and brings about win-win situation between user and enterprise.The main contents of this paper are as follows:considering the difference between traditional projector and laser projector, the article chooses appropriate technical parameters of suitable measuring schemen; considering that there is no uniform speckle evaluation mechanism, so the article develops a speckle computation system via a scientific and reasonable method. Talking about the measuring instrument, standard uses the new high precision measuring device, which is developed by our laboratory research. This new measuring device make the parameter test becoming simpler and more precise. Combining laser projector appearance, performance, reliability, safety and performance requirements, the article formulate the performance requirements of the test, inspection method and inspection rules. At the end of the article, attach the product standards of laser projector developed firstly in china, which provides a bridge for the inspection, exchange of technology, trade basis between domestic and foreign, thereby to promote the development of the laser projector.
