Transformation and upgrading of TV sets?

The TV set has evolved from the earliest split black-and-white TV set to the integrated black-and-white TV set in the 1980s. This kind of color TV is not enough to be imported from Japan, such as the Yellow River and Beijing in China. Toshiba, Hitachi and Panasonic were all imported from Japan, which was also famous at that time. In the 1990s, Changhong was good as an independent color TV set in China, or from an all-in-one machine to a single-chip four-chip TV set, and so on. By 0304, there was a back projection. But it was basically eliminated within two years after it came out. Now plasma liquid crystal is more popular, and the future development direction of TV is lighter and more convenient, which may be as thin as a wall hanging.
