What is Multi-Touch?
Multi-touch refers to the ability of a touch surface to recognize two or more contact points simultaneously. It has been widely used in consumer mobile devices such as Apple iPhone and iPad, tablets and other smartphones. It provides customers with a more direct interaction with their electronic devices by allowing gestures which require two fingers to complete such as zoom in/out, rotation and two finger tap.

What is a LED monitor?
The term "LED monitor" generally refers to a monitor with a LCD panel and a LED backlight. A typical LCD monitor uses cold cathode fluorescent lamps (CCFL) as a light source to illuminate the LCD panel. In an LED backlit monitor, white LEDs (Light Emitting Diodes) are used as the light source. Environmentally friendly LED backlights provide the following benefits:
- About 50%* less power consumption compared to traditional CCFL monitor
- 20,000,000:1 MEGA Dynamic Contrast Ratio
- Environmentally friendly mercury-free backlight
- Low EMI (Electro Magnetic Interference)
- Slimmer design
- Weight reduction
