Cavities with mirrors spaced specifically to amplify red, blue and green light are grouped in bunches of three, each of which corresponds to a single dot, or pixel, on the display.
为增强红蓝绿光，镜子会隔成特定间距，其空腔分为三束，每束相当于显示屏上的一个单点，或像素。
In digital imaging, graininess may occur as a result of printing an image, the pixel resolution of which is too coarse, or as a result of using a printer with poor dot resolution.
数码成像时，颗粒状可能会在图片打印时像素分辨率过于粗糙或使用点分辨率过低的打印机时出现。
With such a display, each dot, or pixel, on the screen corresponds, or is "mapped," to a bit in the screen buffer.
用这个显示方法，萤幕上的每一点或光点相对或“图记”于荧幕缓冲器内的一数元。
