Projected Capacitive TouchScreen Technology
Projected Capacitive Technology permits more accurate and flexible operation by etching the conductive layer on the touch screen. Projected Capacitive Technology (PCT) is a more robust solution versus resistive touch technology since PCT's top layer is made of glass. DOPO's Projected Capacitive Touchscreens can support resolutions up to 1024 x 1024 with a sampling rate of 50 times per second. Our Projected Capacitive Touch Screens uses multiple layers of glass wih optical lamination in assembly process. This makes the PCT touch screen the same touchness as tempered glass which could 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 touch screen).

Custom Projected Capacitive Touch Screens
Our capacitive touch panel design can be paired with housing design from the customers to cover their lens or replace the physical buttons on its original module. DOPO is also capable of doing the customized shape needed to pair with customer's mechanical design.
With the assistance of the simulation software, equiment with high accuracy and simplifying assembly process, DOPO is capable of making the sample in shorter period and with lower development charge.
Projected Capacitive Touch Panel Applications
Since Projected capacitive touch panels can sense gloved hand gestures, it is a popular and logical choice for the medical and industrial industries. Its robust design also makes it a hard-wearing logical choice for point of sales and consumer products.
Application
■ Mobile phone
■ Car navigation (GPS)
■ E-book
■ MID (tablet PC)
■ Handheld game device
■ Camera
■ Electronic photo frame
| 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 without hardcoat |
| Stylus not a must | Need stylus, easy to lose |
