FAQ (Frequently Asked Question)

How do you tackle the fact that you are buying LEDs in batches and that the average life expectancy is 10 years?
As a close partner of Cree, Retop is entitled to order the designated bin of LEDs from Cree, especially for the ultra brightness batch. After Retop gets LEDs from outside supplier (Nichia or Cree), we're equipped to do further sorting based on our binning facility to guarantee the further narrow.

Elaborate on the anticipated method you will use in order to guarantee color accuracy.
The radiance image calibration system serves for achieving final color variance X/Y: 0.003 and +/-2.5% for brightness variance.

What diagnostics are available for monitoring the health of the overall display and its individual components?
Retop's system has the following characteristics to manage monitoring the health of overall display and individual components.
1. We have real-time online detection and diagnosis system to detect the working state of the display.
2. The environment monitoring system can monitor each module of the temperature and humidity as well as the status of power supply, fans, smoke, etc.
3. The dynamic redundancy system can make the display and each module achieve zero failure.

Are you able to address each LED module individually?
Yes. We have Module Address Software. The interface of this software can show you all the modules.

How does the calibration of the display perform?
Calibration is based on LED module. It is conducted by using the radiant image equipment.

How do you correct the brightness level differences after the replacement of a LED module to keep the brightness of the new product?
Retop system can adjust the brightness based on each strip with range of 8 bits. First, upload the old calibration data to the receiving card. Second, adjust the brightness to keep the same brightness as the old one. Last, enjoy your new display.
