What is a self-luminous dashboard? What is the difference between manual opening and ordinary dashboard?

Traditional automobile instrument lighting uses ordinary small bulbs to reflect to the dashboard many times, which leads to large light loss and uneven light emission. Especially small bulbs are easy to be damaged and need to be replaced frequently, which is very troublesome; This is a waste of time and money. The cold light meter does not need to be replaced (the design life of the cold light meter is more than 654.38+00,000 kilometers according to the night display). In particular, the cold light instrument, scientifically using ergonomics, is designed into light blue and light green according to the principle of human vision, and it is not tiring to watch the eyes for a long time. The brightness and color of the cold light instrument can be adjusted at will according to different personal preferences, which can fully satisfy the driver's desire. In a word, it is the aspiration of the people to install a cold light meter on the car, which is the inevitable trend of the development of the automobile industry.
