LED display (LEDdisplay, LED Screen): also known as electronic display screen or floating word . By LED Dot Matrix and led pc panel composed by red, blue, green blinking LED lights to display text , images , animations , video, content can be replaced at any time , all components are part of the modular structure of the display device . Traditional LED display usually consists of a display module , control systems and power systems. graphic lcd modules consists of the lattice structure, responsible for the light-emitting display ; control system by controlling the corresponding region of the light off , the screen can display text, pictures, video and other content, color, color screen is mainly used to broadcast text , all the main color is playing the animation ; supply system is responsible for the display of the input voltage and current into a voltage and current needs .
2, the liquid crystal display (LCD) display for a type of digital type watches and many portable computers. LCD displays use two sheets of polarizing material with a liquid crystal between them is added. When current flows through the liquid causes the crystals to Graphic LCD Module rearrange , so light can not through them . Therefore, each crystal like blinds , both allow light to pass through and can block the light. Liquid crystal display (LCD) technology information products are currently moving light, thin, short, small development goals , with a long history in the computer peripheral products in the display is certainly no exception. Under easy to carry and transport for the former title , such as traditional CRT display CRT monitors and LED display boards, etc. , are subject to too large or very huge power consumption and other factors , could not reach the actual needs of the user. And the development of LCD technology just to meet the current trend of information products , whether it is at right angles to the display , low power consumption , small size, excellent radiation or zero
