brightness ratio

基本解释

Regardless of this fact, there is need to optimize all general specifications, such as brightness, contrast ratio, color gamut, and so on.
即使这样，包括亮度、对比度、彩色色域等所有常见的规格都需要优化。
In view of the incompleteness of the condition in testing image intensifiers output signal-to-noise ratio, the brightness gains effect on output signal-to-noise ratio is expounded.
亮度增益和等效背景照度是衡量像增强器性能的两个重要参数，针对这两个参数的测试要求，阐述像增强器亮度增益和等效背景的测试原理和测试仪的结构设计。
Its advantages are discarding thick and heavy cover glass, high utilization ratio of energy, high brightness of refraction image, easy to making plane frame of hologram for display and easy to carry.
该法优点是不需要厚重玻璃衬板，光能利用率高，重现像亮，易于把全息图制成平面一体化构架，便于携带。

Interestingly, HP won't discuss the other specs in great detail, except to say that the contrast ratio and brightness levels are comparable to most notebook screens.
