The Acrylate resin layer has lower dielectric constant(
3.5)
better optical transparency
and can be spin-coated as a flat surface film easily. By using resin as passivation layer in the array process
the vertical gap is increased between the Common ITO and bus line and plannar the devices. This reduces unwanted capacitive coupling and enables the pixel electrode to be extended over the gate and data lines
thus increasing aperture area
specifi-cally decreases power. In this work
there were some problems between the resin passivation layer and pixel ITO
such as Mo attack
missing ITO and so on. After optimizing the process of ITO Etching
photosensitive resin and non-photosensitive resin perfectly match with ITO etchant and Resin Coating
the resin passivation layer is sucessfully applied to the TFT-LCD.
