以往的CRT显示器主要用于文本显示、工程制图和桌面排版等领域,100～110流明/平方米的亮度已基本满足用户的需求。而在观看电影、3D游戏等动态图像时,由于眼球对动态图像的敏感度不同,只有在足够明亮的条件下才能感觉到各种色彩。e刀客在用普通CRT显示器观看动态图像时也总觉得太灰暗,只好通过关灯、拉窗帘等方式来降低周围环境的影响。 如今,许多CRT厂商进行了技术改进,使显像管电子枪能在单位时间内发射更多的电子来击打荧光质,从而产生高亮效果。然而由于受到CRT技术本身的局限,往往只能达到屏幕局部亮度增强的效果,即某一激活窗口可以实现亮度增加,而其它显示
Previous CRT monitors are mainly used for text display, engineering drawing and desktop publishing and other fields, 100 ~ 110 lumens / square meter brightness has been basically meet the needs of users. When watching movies, 3D games and other dynamic images, due to the sensitivity of the eye to dynamic images, only under bright enough conditions can feel a variety of colors. e knife off when using ordinary CRT monitors to watch dynamic images are always too dark, had to turn off the lights, pull the curtains and other ways to reduce the impact of the surrounding environment. Nowadays, many CRT manufacturers have made technical improvements that enable CRT guns to emit more electrons per unit time to strike the phosphor, resulting in a brightening effect. However, due to the limitations of the CRT technology itself, it is often only possible to achieve the effect of enhancing the brightness of the screen locally, that is, the brightness of an activated window can be increased, while the other displays
