投影机的起步其实并不算晚,早期的投影机是采用三枪或单枪CRT技术,虽然说CRT技术已经十分成熟,但是由于应用到投影机需要较高的成本,而且体积大、耗电量大、操作复杂等缺点使得CRT投影机在家用领域内处于被淘汰的位置。投影机真正得到高速发展是近几年的事情,尤其是LCD和DLP技术的广泛应用,使投影机得到飞速的发展,并迅速普及到家庭影院系统中,投影成像的高速发展,加快了家庭实现高清的步伐。 Projector is actually not too late to start the early projector is the use of three shots or single shot CRT technology, although the CRT technology has been very mature, but due to the projector requires a higher cost, but also bulky, power consumption Large quantities, complex operations and other shortcomings make the CRT projector in the field of home was eliminated. Projectors really get rapid development in recent years things, especially LCD and DLP technology is widely used, so that the projector has been rapid development and the rapid popularization of home theater systems, the rapid development of projection imaging, to speed up the family to achieve HD pace.
