Similarities and differences between LCD and LED
Outdoor LCD advertising machines are very common in our daily life. They are scattered in places such as subway stations, bus stations, shopping malls, office buildings, etc. There are many types of advertising machines, but do you really know the difference between them? The most common types of advertising machines are LCD and LED. The following will explain the difference between outdoor LCD advertising machines and LED advertising machines, and what similarities and differences they have.
Outdoor LCD advertising machines are actually what we often call LCD screen advertising machines. The structure of LCD is composed of two parallel glass, with the LCD screen placed between the glass. There are many vertical and horizontal small wires between the two glasses. These rod-shaped crystal molecules are controlled by plugging in electricity to change direction and extend the light source to refract light to form images.
For high-end companies, it is a particularly comprehensive modern information technology that provides customers with comprehensive product information and marketing information. So what is an LED advertising machine? LED advertising machine is a practical new dynamic advertising information media, at the forefront of consumption. The light source in the ball is a high-brightness and large-angle light-emitting diode array.
After the embedded microcomputer IC processes the graphic information written by the PC and stored in the memory, it continuously turns on and off specific LED points according to the actual clock frequency. Under this effect, when the human eye is lingering, the graphics required by the user will appear in the visual space by chance, and float in the 360-degree visual range. The most obvious feature of LED advertising machines and outdoor LCD advertising machines lies in the display of advertising machines. The brightness level of LED is relatively strong, and it can be seen clearly even from a long distance, which is suitable for outdoor applications.
LCD is not as bright as LED, but it is very clear at close range, which is very suitable for indoor use. Compared with LCD, LED display effect is clearer than LCD. Compared with LCD, LED advertising machine is thinner and more convenient to use in various high-end structures and appearances. In general, compared with LCD, LED display has more advantages in brightness, power consumption, visibility range and refresh rate, so the difference between LED advertising machine and outdoor LCD advertising machine is still very large.Buyers can choose corresponding products according to different characteristics.
