- Companies are persistently attempting to cut production cost in flat panel
display market. Recently, flexible substrate was introduced to the market that
traditionally used glass substrate. This entailed request for enormous change
in manufacturing process and equipment as well.
Manufacturing process was taken a look at to find that it still uses
photolithography to operate patterning. Photolithography process uses vacuum
plating equipment to vaporize thin film composition materials to plate upon
substrate. It includes exposure and developing processes along with mask. Thin
film which is patterned through the conventional equipment, material, and
processes has complicated manufacturing process and big material loss that it
is difficult to cut down production cost. Moreover, FPD substrate is in
large-size trend to cause difficulty in large-size photomask production and
radical increase in price.
In order to resolve this issue, companies within flat panel display industry
like Samsung Electronics, LG Electronics, and foreign laser related makers are
investing in maskless exposure equipment development using laser technology
that doesn' t require photomask.
Laser exposure technology is not able to completely replace delicate
photolithography technology yet in TFT-LCD industry where delicate patterning
is required. However, it is slowly applied in flat panel display industry
based on the persistent research development accomplished so far. It is
expected to move on to entire electronic industry field including RFID, solar
cell, sensor, and memory later on.
Recently, FPD market began unlimited competition for high quality and
production cost reduction. It is in desperate need for manufacturing method
that can expand OLED backplane LTPS technology, simplify manufacturing
process, and reduce production cost. In a situation like this, technology
using laser is successfully applied in mass production process as a
replacement for conventional manufacturing process. Its application is
currently being gradually expanded to crystallization process, thin film
direct patterning, glass cutting, panel packaging, and repair fields.
Displaybank published "Advanced Laser Applications for Next-Generation FPD
Manufacturing Process" report regarding cutting-edge laser application
technology which is becoming hot issue to flat panel display industry related
companies and is actively being research-developed.
