液晶投影电视机采用了许多的高新技术,因而其信号处理的电路设计比较可靠,故障率较低。液晶式投影电视机常见故障集中在灯泡及其灯泡的驱动电路上,灯泡衰老及损坏是所有液晶式投影机都会遇到的问题。 1.液晶式投影机灯泡的特点液晶式投影机一般都使用高亮度和高效率的金属卤化物灯泡,这是对高压水银灯加以改良的灯泡。它的发光管内除水银和氮气外,还封入了金属化合物,这些化合物在水银蒸气放电的电弧中混杂着各种金属蒸气。液晶式投影电视机由于使用了这种灯泡,图像清晰度和色彩效果都十分的理想。由于投影机长时间使用,
LCD projection TV uses a lot of high technology, so its signal processing circuit design more reliable, low failure rate. LCD projection TV common failures focus on the lamp and lamp drive circuit, the lamp aging and damage all LCD projector will encounter problems. 1. LCD Projector Bulbs Features LCD projectors generally use high brightness and high efficiency metal halide lamp, which is a high pressure mercury lamp to be improved bulb. In addition to mercury and nitrogen in its LED, metal compounds are encapsulated, and these compounds are mixed with various metal vapors in the arc of mercury vapor discharges. LCD projection TV Thanks to the use of such a light bulb, image clarity and color effects are ideal. As the projector for a long time,
