Analog LED TV uses cathode-ray tubes as displays, while digital TV uses flat-panel displays such as LCDS, plasma or leds. As a result, analog TV sets are large and bulky compared with digital ones. Analog TV also consumes more energy than digital TV.
Analog TV is generally limited to less than 30 inches because of the its difficulty of creating larger screens without any substantial improvement in image quality. Digital led tv wholesale has developed rapidly these years, and digital TV over 32 inches has become the mainstream of the market.
