CRT 图象质量和系统性能的指标包括诸如分辨率(斑点尺寸和形状、线宽、MTF)、会聚度、亮度、动态范围、光栅形状、线性颜色纯度特性,等等。一旦确定了定义(可寻址象素,扫描速率,输入信号特性等),要实现这些性能就需要对屏幕尺寸、偏转 Indicators of CRT image quality and system performance include features such as resolution (spot size and shape, line width, MTF), convergence, brightness, dynamic range, raster shape, linear color purity characteristics, and the like. Once the definition (addressable pixels, scan rate, input signal characteristics, etc.) is defined, the screen size, deflection
