日本伊势公司研制成发光点数为320×240的三色矩阵荧光显示屏.该屏的结构与一般荧光显示屏相似,有一直热式阴极、由金属薄片光刻而成的栅极和涂复有发光粉的阳极.在栅极和阳极的作用下,从阴极发出的电子有选择地轰击以矩阵排列的点状发光粉发光,从而形成图案.不同的是,伊势公司研制成的三色荧光显示屏的发光点阵是用三种发光粉在阳极上光刻而成.这三种发光粉是发红光的(ZnCd)S∶Ag+
Japan’s Ise developed a luminous point for the 320 × 240 three-color matrix fluorescent display screen structure similar to the general fluorescent display, there has been a hot cathode, the metal foil from the photolithography of the gate and coating Anodes with a luminescent powder An electron emitted from the cathode selectively strikes the dotted luminescent powder arranged in a matrix to emit light under the action of the grid and the anode to form a pattern except that the three colors The luminescent dot matrix of the fluorescent screen is made by photolithography of the three phosphors on the anode, which are red (ZnCd) S: Ag +
