It is able to address display sizes up to 45 inches with a very wide aspect ratio, supporting liquid-crystal display (LCD) and organic light emitting diode (OLED) display technologies.
The MXT2912TD-UW reduces the need for multiple touch controllers within a vehicle’s human machine interface (HMI) display. This single-chip touch controller provides, what is claimed to be, the highest report rate for wide displays and is independent of the display resolution, helping achieve the same user experience that has become accustomed with the smart phone.
Also supported by the maXTouch family’s intrinsic Signal-to-Noise Ratio (SNR), the MXT2912TD-UW enables detection and tracking of multi-finger thick gloves through a wide variety of overlay materials and thicknesses, even in the presence of moisture.
Driven by the ISO 26262 specification for functional safety in road vehicles, it contains a variety of safety related features, simplifying the display module system’s path to functional safety certification. These include periodic self-test, touch sensor test, internal flash and RAM tests, full signal data path integrity checks and additional microprocessor (MPU) core testing. The embedded firmware is developed to Automotive SPICE processes.
Software support includes Microchip’s maXTouch Studio development tool and maXTouch Analyzer inspection tool for production line testing.
