Automating LCD displays testing with machine vision
Checking for dead pixels on LCD displays is a challenge. Visual inspection can take about a minute as you have to cycle through having on all the reds, all the greens, all the blue pixels and then all on together as white, while checking every time to try and spot dead pixels.
Automating as many processes as possible is the key to being competitive in contract manufacturing. China is losing its edge of ultra cheap labour and customers are realising that highly automated production facilities can be price competitive with the advantages of being located nearby to ensure quality and a short distance and time for goods to be delivered to their markets.
