Adjusting the Luminance Automatically Using a
Sensor
Connect the sensor (not supplied) to the unit alignment controller. (See
page 11 for connection.)
First, attach the sensor to a cell with correct luminance and make the
controller read the correct data. Then attach the sensor to the cell to be
adjusted. The luminance of this cell is automatically adjusted so that the
data is the same as the correct data.
When you replace a cell, you can set the luminance of that cell to the same
level as the remaining cells.
