How does ViewSonic ensure brightness uniformity for the LED pixels on a DVLED display?

Answer: The brightness of each LED is calibrated using a calibration software to attain brightness uniformity on the DVLED display. When LEDs from the factory are not calibrated, the brightness will be different across the display. A brightness calibration is recommended if there are differing levels of brightness.

Why do some DVLED products have Copper wires or Gold wires as the bonding wire? What's the difference?

Answer: Gold (Au) is used in mid- to high-end products as the bonding wire. Copper (Cu) is often used in mass-marketed products as the bonding wire. Products using Gold have a higher and more consistent product quality. Heat also dissipates less, making it more energy efficient (~10%). Since it has more stable physical properties, it relativel...

What is a partitional power-on protection, and why is this design used for dvLED?

Electrical appliances at the moment of startup have a much higher current and power draw than normal operation. Since dvLED products are composed of many LED modules and if they are all turned on at the same time, a sudden increase in power draw may occur resulting in electrical wear and tear.  Solution To ensure the electrical ...

If there is no opening for the connectors, module should be placed bead-side down to prevent connector damage. Product Safety The following components on the LED module can be damaged if not handled well:  LED Bead damage diagram ...

How do I properly store DVLED Display LED module(s)?

LED Modules (either damaged and/or undamaged) should be stored in module boxes according to the following packaging steps when not mounted on the display. If there is a shortage of module boxes, please contact Customer Service. Please refer to the Proper LED Module Packaging SOP for full details. Solution Obtain the Module Box(s). Eac...

How many Receiving Cards and Transfer Boards are there on a DVLED Display?
