What if the display was EOL?
Firstly we will check with the original LCD panel manufacturer,if the panel was really end of life,we will get the final production quantity and lead time,and negotiate with our customer help them to do the last buy.Sometimes the last buy quantity will be large,to make sure the project will move forward we will buy the LCD panel together with our customer,just to make sure customer will get the panel without any problem.
If the display driver was end of life,there will be an alternative version or an update version,we will move to the new version and make new samples for our customer to do double check.
For the backlight, FPC and touch panel, usually we invest our own tools to guarantee long term stable supply.
We can not guarantee that our display will never EOL,cause every brand of LCD panel and driver have their own lifetime,but what we can guarantee is we will help our customer and make an alternative solution to replace the old display,we will take the responsibility and always stand with our customer.
