What are the advantages of LED display?

  The full name of LED is Light-Emitting Diode, that is, we often hear of light-emitting diodes. It is a semiconductor electronic component that can emit light through trivalent and pentavalent elements. What we call LED display refers to the LED (light-emitting diode) light-emitting components as the backlight of the LCD screen LCD. That is, we sayLED displayIt does not mean light emitting diodes. So what are the advantages of LED display? The following is the introduction of the editorial of Vishay.

  The advantages of LED displays are:

  1. Security:The unit's operating voltage is roughly between 1.5-5v and the operating current is between 20-70mA.

  2. Energy saving:The power of a single unit is generally 0.05-1w, through the cluster approach can be tailored to meet different needs, with little waste. Using it as a light source, the power consumption under the same brightness is only 1/8-10 of ordinary incandescent lamps.

  3. Long life span:The standard lifetime of the luminous flux decay to 70% is 100,000 hours. A semiconductor lighting fixture can be used for 50 years under normal circumstances, even if the long-lived people, a lifetime of up to 2 to 3 LED lamps and lanterns.

  4. No mercury hazards:Waste can be recycled, no pollution, unlike fluorescent lamps which contain mercury. Since there is no ultraviolet and infrared rays in the spectrum, there is no heat and no radiation, which is a typical green lighting source.

  5. High light efficiency:The spectrum is almost entirely concentrated in the visible light frequency, the efficiency can reach 80%-90%. while the light efficiency is almost the same incandescent lamp visible light efficiency is only 10%-20%.

  6. Reliable and durable:There are no tungsten filaments, glass shells and other easily damaged parts, so the abnormal scrap rate is very small and the maintenance cost is extremely low.

  7. Application flexibility:Small size, can be flat package, easy to develop into thin and light short products, made of points, lines, surfaces of various forms of specific applications.

  8. Short response time:Adaptable to frequent switching and high-frequency operation.

  The above advantages of the LED display screen for you to share here, and, LED display screen can provide up to 160 ° wide viewing angle, can display a variety of text, digital, color images and animation information, but also can play TV, video, VCD, DVD and other color video signals, multiple display screen can also be networked broadcast.
