The invention relates to a multimedia information display system based on an LED projection module structure. The display system comprises a projection screen and a plurality of LED projection modules, and the LED projection modules are arranged on a support respectively, wherein the support is over against the projection screen, and the LED projection modules project images to the projection screen respectively to form integrated frames. Each LED projection module comprises a box body, an LED light source, a first optical lens set, a DMD, a second optical lens set, a projection lens set, a DMD driver, a module controller, an LED radiator, a DMD radiator, a screen image joint information detector, an LED driver and a position and direction adjusting mechanism. According to the multimedia information display system, manufacturing cost and energy consumption of a large screen display system are remarkably reduced, reliability of the system is improved, and the defects that a conventional projection displayer is small in screen area, low in brightness, short in service life, and large in projection depth distance are overcome.
Description
technical field [0001] The invention relates to a multimedia information display system, in particular to a multimedia information display system based on an LED projection module structure. Background technique [0002] With the development of industrial and agricultural production, the improvement of social and cultural education, and the advancement of network technology, it is necessary to be able to support multiple A high-quality large-screen video display system with network access. In recent years, the brightness and light efficiency of semiconductor light-emitting devices (LEDs) have improved rapidly, and they have become energy-saving lighting products that have been developed by the country. LEDs have the characteristics of narrow beams, long life, many colors, and small size. It has been used to replace gas discharge lamps as light sources for projection displays. Contents of the invention [0003] In order to solve the above technical problems, the object of...
