The use of a trough-shaped CRT shadow mask, distance of up to 0.24mm, it is a combination of SONY Trinitron and traditional grid-like mask mask punctate characteristics: pure flat two-dimensional extension of the trough-shaped mask, Compared to traditional point-like mask to space more available to more electronic liquidity to allow more light to reach the screen, the CRT image accuracy, brightness, contrast and color purity has been improved, so more light a clearer picture, and this structure is also conducive to the improvement of resolution and distance.

该显像管使用了槽状荫罩，点距可达0.24mm，它综合了SONY特丽珑栅状荫罩和传统点状荫罩的特点：纯平面两维伸展的槽状荫罩，比起传统点状荫罩来间隙更多，可得到更大的电子流通量，让更多的光线到达屏幕，所以显像管的图像精度、亮度、对比度和色纯度都有了提高，从而获得更亮更清晰的画面，而且这种结构也有利于分辨率和点距的提高。
