根据采用投影技术的不同,投影机可以分为CRT投影机、LCD投影机和DLP投影机三种。 CRT投影机 CRT(Carhode Ray Tube,阴极射线管技术)投影机可以把输入信号源分解到R(红)、G(绿)、B(蓝)三个CRT管的荧光屏上,从而在大屏幕上显示出彩色图像。CRT投影机的优点是显示的图像色彩丰富,还原性好,具有丰 According to the different projection technology, the projector can be divided into CRT projector, LCD projector and DLP projector three. CRT Projector CRT (Carhode Ray Tube) Projector The input source can be decomposed into the fluorescent screens of the three CRTs of R (red), G (green) and B (blue) so that on the large screen Shows a color image. CRT projector has the advantage of displaying rich color images, good reduction, with abundance
