These are the natural development of membrane keyboards.
“Capacitive touch” technology is able to sense touch, eliminating the need for the mechanical and metal actuators that are normally used in traditional keyboards.
With OXI Group you can get that special “touch” thanks to the various materials that can be used to produce keyboards designed for every type of environment. It’s also possible to create a custom design highlighting the incredible details and the remarkable aesthetic impact of the capacitive keyboard.
Choose the ideal material for your frontpiece panel
The sensor is the interface element between the frontpiece and electronic board of a capacitive system.
It is made of polyester film using the latest technologies for both conductive inks (nanotechnologies) and printing techniques that enable the creation of thin conductive tracks only a few microns thick.
All the sensors built by OXI Group are tested with special equipment that verify their perfect functioning, guaranteeing the capacitive system the highest quality performance.
In touch technology systems, backlighting offers a customisable aesthetic effect. The LEDs used make it possible to obtain a “play of light” for each type of keyboard.
The advantages of using them are: creation of a wide range of colours using RGB technology, the possibility to vary the light intensity freely, reduced consumption in terms of current, the suitability for wireless applications, and reduced consumption in terms of voltage for simpler power management and fewer issues.
The OXI Group R&D department has just developed the possibility of achieving customisable lighting by differentiating each key using specific hardware and firmware techniques.
The development of dedicated electronics is essential for touch technology systems.
At the centre of the electronics there is a micro-controller which is adequately programmed to act as interface between human and machine.
The micro-controller has the difficult task of managing a considerable flow of data originating from the sensors and reworking them to allow communication between the keyboard and the devices to be controlled.
OXI Group studies and designs electronic boards to offer cutting-edge products that are high-performing and compatible with the customer’s end system, implementing communication protocols such as I2C or SPI, or sending ON/OFF or PWM (pulse-width modulation) “clean signals” for the activation of power or lighting devices.
