LCM Development & Technology - Introducton of TOUCH PANEL
 
 
   
    The touch panel is input devices that apply the film processing technologies the company has acquired while working on plastics film panels (PEP). Since the keyboards themselves are transparent, the touch panels can be placed directly on top of a display device.  
 
 
   
   
   

The film is situated on the top side, making input possible with a lightly touch.
    Transparent touch key panels have a combination film and glass structure that offers high
     

tran-smissivity and rigidity.
    In lin with your application needs, you have option of choosing either an digital touch panel that has the
      necessary keypad patterned on it or an analog touch panel that can perform continuous recognition.
 
   
     
 
    A transparent electrode is formed uniformly over the entire effective surface on the film and glss of touch panel. (See fig.1)  
   
   

The touch panel has numerous push-button switches
as keys arranged within a matrix. (See fig.2)		  
   
To locate the X and Y coordinnates, voltage Vx taken from the Y electrode and voltage Vy taken from the X electrode are converted into digital data and assigned coordinates. (See fig.3)
