SITO touch is a touch technology that relies on the use of a single layer of ITO (indium tin oxide) to sense touch signals. In this technology, the sensing metal wires for the X and Y axes are placed on the same layer of ITO and then bonded to a glass substrate or polyester film (PET) to form a touch panel.
Compared to traditional double-layer ITO technology (DITO), SITO touch technology simplifies the manufacturing process because it reduces one ITO alignment and bonding process, thereby reducing material costs. This gives SITO touch technology significant advantages in terms of material list (BOM) cost limitations and rapid market launch for mid to low price smartphones.
However, SITO touch technology also faces some challenges. Due to the concentration of sensing lines in one layer, it may lead to excessive capacitance values, thereby reducing the accuracy of touch control. In addition, the simplification of panel structure may also lead to a decrease in strength, which is currently a technical challenge that needs to be overcome.
Overall, SITO touch technology has broad application prospects in the mid to low price smartphone market due to its simplified production process and cost-effectiveness, although some technical issues still need to be addressed.
