阴极射线管彩电(CRT-TV)历经半个多世纪的发展似乎已达至极限。目前最大的荧屏为38英寸,要制造更大尺寸的阴极射线管无论材料、结构、工艺上都相当困难。由电子束扫描而形成的图像其清晰度、色彩、几何变形也难于进一步提高和控制。画面闪烁、辐射等射线管从“娘胎”里就带出的“胎记”更是无法逾越的死区。由此看来,要制造更大画面并且具有高分辨率、高画面素质而又方便使用的显示器,只有舍弃阴极射线管(CRT)。
It seems that cathode ray tube television (CRT-TV) has reached its limit after more than half a century of development. At present, the largest screen 38 inches, to produce larger cathode ray tube regardless of material, structure, technology are quite difficult. The image formed by the electron beam scanning is also difficult to further improve and control its sharpness, color and geometric deformation. Screen flashing, radiation and other tubes from the “womb” in the “birthmark” is insurmountable dead zone. In view of this, to make a larger screen and have a high-resolution, high-picture quality and easy-to-use display, only the cathode ray tube (CRT) is discarded.
