Capacitive touch panel works through body's current induction. When finger is on or close to touch panel surface, due to body electric field, the user and touch panel surface forms one coupling capacitance.
For high frequency current, capacitance is direct conductor, then fingers suck a small current from the contact point, through amplifying and accurately calculating this current signal,
Finally the controller works out the touch point position
Projected Capacitive Touch Screen Technology:
Projected Capacitive Technology permits more accurate and flexible operation by etching the conductive layer on the touch screen.
Projected Capacitive Touch Screen uses multiple layers of glass or film with optical bonding in assembly process.
Cover lens is usually made by tempered glass which can stand against shock and impact.
Projected Capacitive touch panels are embedded with high performance IC and users can enlarge, shrink, rotate, flip and drag pages easily due to the multi-touch gesture support (multi touch screen).
|Comparison between Capacitive Touch Panel and Resistive Touch Panel|
|Capacitive Touch Panel||Resistive Touch Panel|
|Touch (no pressure needed)||Press (pressure activated)|
|No calibration required||Calibration required (resistance drift on film)|
|Better Durability, No significant aging||Display turns white when aging|
|Handles high temperature||Film breaks down at high temperature|
|Better Transparency, less optical power needed||Low transmission|
|Can be vandal-proof (thick glass/plastic)||Easily damaged (thin top layer)|
|Scratch Resistant (with glass)||Prone to scratch|
|Stylus not a must||Need stylus, easy to lose|
The structures explanation:
* P G=PET Glass (cover lens is PET and touch sensor is glass).
* G G=Glass Glass (cover lens is glass and touch sensor is glass).
* G F/F=Glass Film Film (cover lens is glass and touch sensor is film film).
* CG= Cover Glass, OD= Outside Dimension, VA= Viewing Area.
Custom Projected Capacitive Touch Screen:
Our capacitive touch panel design can be suitable for housing design from the customers to cover their lens or replace the physical buttons on its original module.
we are also capable of doing the customized shape needed to suit for customer's mechanical design.
With the assistance of the simulation software, equipment with high accuracy and simplifying assembly process, we are capable of making the sample in shorter period and with lower development charge.
