The marketers of Wittem, a creative LED display manufacturer, often contact customers when selling LED high-definition displays and ask them why the price of your same display is so much higher than others? For example, P4LED display. Generally speaking, P4led high-definition display screen refers to the pixel pitch of 4.0mm, but the pixel pitch of the led display screen on the market is 4.81mm, which is the internal led screen of p4.81. For customers who do not understand the external environment, some sales staff adopt a blind method, claiming P4 full-color LED display. In this way, the price gap will be more obvious, and many uninformed customers think that good products can be bought at low prices.
