aperture of screen

英 [ˈæpətʃə(r) ɒv skriːn]

美 [ˈæpərtʃʊr əv skriːn]

筛孔

When you use a small aperture ( large number aperture setting) with a lens such as a zoom lens, half of the split image becomes dark. In this case, use the matte screen to focus.
当您使用变焦镜头并选用小光圈（大光圈数值）时，分裂像一半是黑的，这时可用磨砂屏对焦。
If the aperture is circular, a circular spot of light appears on the screen.
如果孔是圆形的，那么在屏幕上出现一圆形光斑。

Al gate can obviously reduce total gate-line resistance and gate-pulse delay of a-Si TFT matrix used in AM-LCD. It is profitable for increasing the aperture ratio and image quality of high-information-content display screen.
Al栅可明显降低AM－LCD中a－SiTFT矩阵的栅总线电阻及栅脉冲信号延迟，有利于提高高密显示屏的开口率与图像质量。
