我们在显示器上看到的字符,是电子束快速掠过荧光屏画出的线条图样组合,这些线条上的点,是电子束撞击显象管内部荧光粉涂层产生的。无论屏幕大小,线条的数目相同。因此,小屏幕的字符会比大屏幕的要小。一般情况下,一台显示器可以显示至少25行文字,所以显示器至少应该有375条扫描线。由于显示器屏幕上的字太小,将迫使你靠近屏幕,造成不良的工作姿势,尤其使脖子和肩膀的肌肉紧张。除此之外,过小的字容易增加你眼睛的负担,使你的眼睛疲劳。 一般要求屏幕文字密集,又必须清晰易读的工作时,最小的屏幕尺寸,不应小于14英寸。如今,显示器扫
The character we see on the display is the line pattern drawn by the electron beam rapidly across the phosphor screen. The dots on these lines are generated by the electron beam striking the phosphor coating inside the tube. No matter the screen size, the number of lines is the same. Therefore, the small screen characters will be smaller than the big screen. Under normal circumstances, a monitor can display at least 25 lines of text, so the monitor should have at least 375 scan lines. As the word on the screen of the monitor is too small, it will force you close to the screen, resulting in poor working posture, especially the neck and shoulder muscles. In addition, too small a word can easily increase the burden on your eyes and make your eyes tired. Generally require the screen text intensive, but also must be clear and easy to read work, the smallest screen size, not less than 14 inches. Now, monitor sweep
