How does surface capacitive touch technology drive a new revolution in human-machine interfaces? （1） 6

In addition to IC, SCT's touch screen structure is also simpler than PCT and easier to overcome noise interference issues in hardware. In addition, through process improvement and breakthroughs in key technologies, SCT's overall solution has a cost competitive advantage comparable to resistive solutions. Taking Wanda Optoelectronics' self-developed optical coating technology as an example, it can increase the light transmittance of touch screens from 87 to 97, while reducing the reflectivity from 12 to 2. More importantly, the yield of optical processing can be controlled at over 90%, eliminating the need for outsourcing processing steps, improving technological autonomy and production capacity, and significantly reducing manufacturing costs.  diode

SCT technology is one of the capacitive touch technologies, and therefore retains many advantages of capacitive touch, such as "better visual enjoyment", "easier and more flexible controllability", and "longer service life"; In addition, SCT has relatively relaxed requirements for touch screen characteristics compared to PCT, and its production technology is more mature, making it have both high yield and low cost advantages. Moreover, in practical operation, users have a greater urgency for single point selection, single point gesture, and handwriting functions than multi touch, and these functional requirements happen to be stably provided by SCT at present. Therefore, before the PCT scheme matures (with stable functionality, patent issues, high production yield, and low cost), the SCT scheme is a touch scheme that meets market expectations very well. diode
