投影机正在以惊人的速度扩大市场容量,有必要从投影机的性能指标出发了解投影机的选购。性能指标亮度的国际单位是ANSI流明,它直接关系到观看者是否能清晰辩认屏幕上的图形文字。现在市场上主流机型的亮度在800ANSI流明左右,原則上亮度越大,清晰度越高,但亮度与环境反差太大同样会损伤眼睛,在普通房间照明环境下的屏幕亮度大致为100Lux,只需在屏幕上投影出200Lux,亮度的图像即可满足要求。 LCD投影机技术指标上常用的分辨率是RGB分辨率,是指投影机在接RGB分离视频信号时可达到的最高像素,如
Projectors are expanding market capacity at an alarming rate, it is necessary from the projector’s performance indicators understand projector purchase. The international unit of brightness for performance indicators is ANSI lumens, which is directly related to whether the viewer can clearly recognize the graphical text on the screen. Now the mainstream models on the market brightness of about 800 ANSI lumens, in principle, the greater the brightness, the higher the clarity, but the brightness and the environment too much contrast will damage the eyes, the brightness of the screen in the general room lighting environment is roughly 100Lux, only To be projected on the screen 200Lux, the brightness of the image to meet the requirements. LCD projector technical indicators commonly used resolution is RGB resolution, refers to the projector in the next RGB video signal can be reached when the highest pixel, such as
