一、液晶片的尺寸及数量 目前液晶投影机主要分为单片式投影机和三片式投影机。液晶板的大小决定着投影机的大小。液晶片越小,则投影机的光学系统就能做得越小,从而使投影机体积越小。一般单片式投影机由于液晶片少、光路简单,可采用较大的液晶片,三片式投影机多采用小尺寸液晶(1.32英寸),便携式三片式投影机常采用0.9英寸或0.7英寸的液晶片。像素是组成图像的基本单位,像素数越大,则图像越细腻。像素数=每片液晶物理分辨率×液晶片个数。例如:SVGA机型 像素数=(800×600×3,即150万像素点。
First, the size and number of liquid crystal At present, LCD projector is divided into single-chip projectors and three-chip projectors. The size of the LCD panel determines the size of the projector. The smaller the liquid crystal, the projector’s optical system can be made smaller, resulting in a smaller projector. The general single-chip projectors due to less liquid crystal, light path is simple, can use a larger liquid crystal film, three-chip projectors use more small-size liquid crystal (1.32 inches), portable three-chip projector often use 0.9 inches or 0.7 inches Of the liquid crystal. Pixel is the basic unit of the image, the greater the number of pixels, the more delicate the image. Number of pixels = physical resolution of each liquid crystal × number of liquid crystal. For example: SVGA model number of pixels = (800 × 600 × 3, that is 1.5 million pixels.
