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.
