问:显示器件有哪些指标? 答:主要有: (1)图象显示面积。电子束管常用矩形屏幕的对角线长度或圆形屏幕的直径来表示,单位是厘米或英寸。平板显示器件及大屏幕显示常用图象的有效面积来表示; (2)分辨率。指图象的扫描行数,行数愈多,图象愈清楚。电子束管常用屏幕上扫描的行数来表示。平板显示器件则用交叉电极的数目来表示。例如:分辨率为100×140线,是指水平方向有100条电极,垂直方向有140条电极; (3)亮度。指器件发光的明亮程度,常用英尺·朗
Q: What are the indicators of the display? A: The main are: (1) image display area. Electron beam tube commonly used rectangular screen diagonal length or diameter of the circular screen to represent, in centimeters or inches. Flat panel display devices and large screen display commonly used images of the effective area to represent; (2) resolution. Refers to the number of image scanning lines, the more rows, the image more clearly. E-beam tube screen commonly used to scan the number of lines to represent. Flat panel display devices are used to indicate the number of crossed electrodes. For example, the resolution is 100 × 140 lines, which means that there are 100 electrodes in the horizontal direction and 140 electrodes in the vertical direction. (3) Brightness. Refers to the brightness of the device light, commonly used feet Long
