Breif Nokia Research Outline

Naif Al and I have researched Nokia marketing strategy and technology research for one year and three months. There is a brief Nokia touch screen reresearch outlines as below and for demonstration with specific photos.


Touch monitor is an important device to detect the user’s touch point and is fabricated on substrates such as glass or PET. Film .The main structure consists of multiple layers of ITO film formed on the substrate by sputtering coating or printing followed by photolitho graphy and etching to form the ITO (Indium tin oxide) pattern. The isolation layer and metal interconnects are coatd afterwards and cut into the designated dimensions. The controller measures the values of the current flow from the four corners and calculates the X, and Y coordinates of the touch location. The raw coordination data is further analyzed and compensated to give the optimized linearity accuracy.
