Product life cycle & How to handle obsolescence

Most of our displays run 7-10 years.  And as long as our customers are still buying the configuration, we would not obsolete the LCD display.  In the case where the LCD IC driver or the color TFT glass used in the display becomes obsolete, we create a design around the closest replacement, identify any differences, and work with our customers on a last time buy strategy to manage any gap in supply while developing the replacement display.
