One Glass Solution
(來源：達宏科技先進股份有限公司)。
Indium tin oxide (ITO) is the conductor material of choice for transparent electrodes due to its high optoelectronic performance. However, two factors have recently combined to encourage the development of alternative materials and structures:
the increasing cost of ITO caused by the scarcity of indium and dissatisfied response time for large size display .
Metal Mesh will be substituted for indium tin oxide (ITO)

Printing Process
Plate Printing
Plateless Printing
Flexographic printing
Gravure printing
Screen Printing
Rotary screen Printing
Inkjet Printing
The advantage of these technologies can be quickly produced and material saving, but still can not be fabrication of fine line width (<5 μm)
