LED stand for Light Emitting Diode,a kind of semiconductor which is used to give and receive the electronic signal into infrared rays or light, using the characteristics of compound semiconductor. [View Details] -
What Causes the LED to Emit Light and What Determines the Color of the Light?
When sufficient voltage is applied to the chip across the leads of the LED, electronics can move easily in only one direction across the junction between the p and n regions. [View Details] - The operational lifetime of an LED Display is determined by the lifetime of the LEDs. LED Manufacturers estimate the LED lifetime to be 100,000 hours under certain operating conditions. [View Details]
- The color and brightness emitted by an LED are determined by the chemical composition and construction. Single-color (monochrome) displays are made up of one color of LEDs [View Details]
- Along with proper brightness, a display must have high contrast for good readability. Contrast is the difference between the background’s “off state” (blank display area) versus the “on state” (illuminated display area) [View Details]

What are LED Type, module size and module resolution?
LED Type is the description of LED lamp, for instance, the brand, the shape in physical, the size of the lamp, etc. [View Details] -
Drive Method, driving IC and Power supply
Drive Method: always we use static, 1/4 scan, 1/8 scan, 1/16 scan, the latter one contributes to less brightness than the former. We always use the static outdoor, and use the different kinds of scan indoor. [View Details] - Viewing angle is the maximum angle at which a display can be viewed with acceptable visual performance. It includes horizontal viewing angle and vertical viewing angle. [View Details]

What are refresh rate and frame rate?
The refresh rate is the number of times a display’s image is repainted or refreshed per second. As it denotes a frequency of a process, the refresh rate is expressed in hertz. That is [View Details]
