Equating the fluid consumption values to
manufacturing cost components in the chart
below gives an indication of the significant
cost advantage of the extrusion process.
Comparison of PhotoResist
The chart below shows the approximate
photoresist cost for an advanced (four-mask)
AMLCD array manufacturing process. Cost of the
photoresist is assumed to be US $32.00/liter.
Cost of wasted material shown in red
parentheses.
Comparison of Cost Graphic
Cost benefits for the color filter process are
even greater. The chart below shows the
approximate color filter resist cost for a 3
color (RGB) color filter process. Cost of the
color filter resist is assumed to be US
$400.00 per liter. The tremendous cost savings
for the color filter process are one of the
reasons that the extrusion-based processes
have made such significant market penetration
in this market. Cost of wasted material shown
in red parentheses.
