If our standard portfolio do not meet your needs, FC can provide YOUR solution, whatever market you are in, wearable, medical, industrial, instrumentation, automotive, aerospace, by engineering a custom display module.
Hover Touch is a whole new Innovation of touch technology combining both mutual capacitance and self-capacitance to reach the floating touch. When the user's fingers are far from the panel, signals are too weak to be detected, and the mutual capacitance signal has not been changed. However, the self-capacitance signals have increased gradually while the fingers are approaching. It can detect the coordinates of the fingers at a certain distance, and then the floating touch function will be fulfilled. When the fingers touch the panel, the mutual capacitance is detected for the electric field change, and the multi-touch function is also fulfilled.
SCHEMATIC OF HOVER TOUCH
2D Touch Principle
3D Touch Principle
There are so many advantages of developing multi-touch and hover touch like:
1. It can be a three-in-one product structure bundled with CG (Cover Glass), touch panel, and display module.
2. CG can apply the surface treatment with AG/AR/AF/AS without affecting the touch effect.
3. Highly noise-resistant ability.
4. It equips with non-touch single-point and multi-touch functions to support up to 5 touchpoints.
5. It can send 38 channels of signal and receive 22 channels of signal and detect up to 836 nodes.
6. It can be controlled accurately on the panel with the passive stylus (with 1mm of diameter). However, it depends on configuration, stacking, and sensing design.
7. It supports Min 10mm / Max 30mm of the floating height with Single-point operation, and the panel can still be controlled.
8. When your hands are stained with water or grease, you can operate the panel normally without worrying about soiling the panel.
9. Wearing non-conductive cloth or gloves, the thickness of multi-point operation can support up to 2mm, and up to 5mm with the single-point operation. The panel can still be controlled normally.
10. Supports Windows and Android operating systems.
11. The speed is greater than 60Hz (in the condition of 10 points of touch).
