Abstract

Overview

Standard Reference: IEC 62908-12-10:2017 Title: Touch and interactive displays - Part 12-10: Measurement methods of touch displays - Touch and electrical performance (corrigendum Nov 2018 included)

IEC 62908-12-10:2017 specifies standard measuring conditions and methods for determining the touch performance and electrical performance of a touch sensor module. It applies to touch sensor modules whose structural relationship (sensor, controller, module, display panel, touch display panel, touch display module) is defined in IEC 62908-1-2. The standard defines environmental and positioning conditions, test tools, and repeatable procedures for laboratory and production test environments.

Key topics and technical requirements

The standard defines measurement methods and reporting for a comprehensive set of touch and electrical performance metrics, including:

Standard measuring conditions
- Environmental and atmospheric reference conditions
- Standard positioning equipment and a human-operator alternative
- Test bar size, shape and material parameters
Touch performance tests
- Accuracy - position error measurement and reporting
- Repeatability / jitter - short-term position stability
- Linearity - deviation along dragged lines
- Reproducibility - consistency across sessions and velocities
- Signal-to-noise ratio (SNR) - touch signal vs. background noise
- Report rate - reporting frequency under specified conditions
- Latency - time from physical event to reported touch
- Electrical noise immunity - response to external electrical interference
- Water droplet immunity - touch behavior in presence of droplets
- Optical noise immunity - behavior under ambient/LED lighting
- Power consumption - measurement procedures for power draw
- Perpendicular touch / hover distance - detection thresholds for proximity
Electrical performance (Annex A)
- Resistance measurements of sensor structures
- Trans-capacitance measurements and procedures
- Required test samples, measurement equipment (e.g., LCR meters), procedures and reporting formats

The document includes figures, test grids and reporting guidance to ensure reproducible, comparable results.

Applications and who uses it

This standard is essential for stakeholders involved in design, manufacture, integration and validation of touch-enabled displays:

Display manufacturers and touch sensor vendors - for design verification and specification compliance
Touch controller and module designers - to validate firmware/hardware performance
Test laboratories and QA teams - to run repeatable production and acceptance tests
System integrators and OEMs - to assess touch performance in final products
Procurement and compliance teams - to specify measurable acceptance criteria

Using IEC 62908-12-10 helps reduce field failures, enable fair vendor comparisons, and support claims about accuracy, latency, robustness to water or electrical noise, and power efficiency.
