Advertising displays are ubiquitous in our lives, found in subways, bus stops, shopping malls, buildings, and more. There are many types of advertising displays, which we've previously discussed. LCD and LED are two such types, but many people are unclear about the differences between them. Below, we'll explain the differences between LED and LCD advertising displays:
I. What is an LCD Advertising Display?
An LCD advertising display, also known as a liquid crystal advertising display, consists of liquid crystals placed between two parallel glass panes. Numerous vertical and horizontal wires connect the glass panes, controlling the direction of the rod-shaped crystal molecules by adjusting the power supply, thus refracting light to create an image. It's particularly suitable for high-end brands' integrated multimedia technology, delivering comprehensive product and promotional information to consumers.
II. What is an LED Advertising Display?
An LED advertising display is a new type of cutting-edge dynamic advertising information dissemination medium. The light source inside the display is an array of ultra-high brightness, wide-viewing-angle LEDs (light-emitting diodes). The built-in microcomputer chip processes the graphic and text information edited and stored in memory by a personal computer. It then precisely lights and turns off specific LEDs in a controlled sequence, while simultaneously rotating at high speed driven by a brushless DC motor. Due to the persistence of vision, the desired graphics and text magically appear and suspend within the 360° visual space of the sphere.
III. Differences between LED and LCD Advertising Machines
The main difference between LED and LCD advertising machines lies in their display capabilities. LEDs are brighter and clearer from a distance, making them suitable for outdoor use; LCDs are not as bright but clearer up close, making them suitable for indoor use. The display effect of LEDs is not as strong as that of LCDs, which can achieve high definition. More importantly, LEDs are thinner than LCDs, making it easier to achieve various extreme structural and aesthetic requirements.
In conclusion, compared to LCDs, LED displays have advantages in brightness, power consumption, viewing angle, and refresh rate. Therefore, the differences between LED and LCD advertising machines are significant.
