PCAP touch screen controllers use tiny changes in electric fields that occur as a finger approaches the touch screen’s surface to detect touch input. Touch detection may become more challenging when using gloves.
To reliably identify gloved contact, whether with latex gloves, cotton gloves, or industrial gloves, projected capacitive (PCAP) touch screen controllers use special algorithms.
When using thick glass, the projected capacitive (PCAP) touch screen controller recognises fewer signals. In order to maintain normal operation with thick glass support and successfully prevent erroneous touch sites, it efficiently boosts signal strength and maintains an optimal noise ratio.
On a different PCB, there is a controller IC for a projected capacitive (PCAP) touch screen. The flexible printed circuit (FPC), which connects the touch sensor to the PCB, will carry the analogue signals. This capacitance data will be transformed into digital touch position data by the controller IC firmware.
Global PCAP touchscreen controller market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
DMC Co., Ltd., a business that specialises in industrial touch screens, will unveil a new Controller Auto Adjustment Tool named “Easy Builder.”
Because projected capacitive touch panels are typically sensitive to ambient noise, each touch controller must be tuned.When appropriate, DMC has historically assisted customers with controller firmware adjustments through remote or in-person tuning by our engineers. However, in some circumstances, it wasn’t always efficient in terms of timing.
In terms of noise reduction, PenMount is renowned for its prowess. PenMount PCAP touch controllers are compliant with standards exceeding CS 10V and industrial-grade EMC standards (with good performance in conducted susceptibility, CS).
Nevertheless, they are aware that various noises are connected to particular locations and pieces of equipment. In order to meet the challenges, PenMount firmware is updated with stronger anti-noise capabilities each time.
They have introduced the Double ADC Average anti-noise adjustment capability with this new edition. PenMount has previously used anti-noise features like Enhanced Driving, Frequency Hopping Mode, and Spike Filter.
