最近,由于新的放电方式的开发,日立制作所发表了高亮度、实用的平面彩色电视样机实验成功的消息。这样“大型壁挂电视”实现的可能性就变大了。近年来,彩色电视越来越朝着大型化方面发展。但是,彩色电视机所用的显象管,其对角线尺寸超过100厘米以上时,重量就达到100kg,深度也有60厘米,作为家庭使用就不太合适了,而且画面也会出现失真。另一方面,投影电视(投射式阴极射线管)其体积一大,发光的方向性就变强,也不是理想的显示器。这样大的屏幕尺寸,如采用液晶、荧光显示管、电致发光等方法的话,也可得到彩色显
Recently, due to the development of a new discharge method, Hitachi has published successful experiments on high-brightness and practical flat color TV prototypes. This “large wall TV” to achieve the possibility of greater. In recent years, color TV is increasingly moving toward large-scale development. However, the color television sets used in the picture tube, the diagonal size of more than 100 cm above the weight of 100kg, the depth of 60 cm, as the home is not appropriate, and the picture will appear distorted. On the other hand, the projection TV (projection cathode ray tube) has a large volume and increases the directivity of light emission and is not an ideal display. Such a large screen size, such as the use of liquid crystal, fluorescent tubes, electroluminescence, etc., can also be color was
