Description (English):

IEC 62908-12-10:2023 specifies the standard measuring conditions and measurement methods for determining touch and hovering performance of a touch sensor module. This document is applicable to touch sensor modules, where the structural relationship between touch sensor, touch controller, touch sensor module, display panel, touch display panel, and touch display module is defined in IEC 62908-1-2. This second edition cancels and replaces the first edition published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - added hovering performance measurement methods, especially in-plane characteristics at a constant distance from the touch sensor; - added pen touch performance.

Abstract

Overview

IEC 62908-12-10:2023 is the International Electrotechnical Commission standard that defines standard measuring conditions and measurement methods for touch and hovering performance of touch sensor modules. Applicable where the structural relationships between touch sensor, touch controller, display panel and modules are defined (see IEC 62908‑1‑2). This second edition (2023) replaces the 2017 edition and introduces significant technical updates, notably hovering performance measurement (in‑plane at constant distance) and pen touch performance.

Key topics and technical requirements

The standard prescribes test setups, procedures and reporting for a comprehensive set of touch and electrical performance measurements, including:

Measuring conditions and setup
- Standard environmental and atmospheric conditions
- Positioning equipment and a human‑operator alternative
- Test tools (test bars) and pen parameters
Touch performance measurement methods
- Accuracy (position error) and how to calculate/report results
- Repeatability / jitter
- Linearity (dragging/line tests)
- Reproducibility (including velocity dependence)
- Signal‑to‑noise ratio (SNR)
- Report rate and reporting time interval
- Latency (end‑to‑end response timing)
- Electrical noise immunity and external noise injection procedures
- Water droplet immunity and optical noise immunity
- Power consumption
- Perpendicular touch/hover distance (Z‑axis detection limits)
In‑plane hovering performance
- Specific procedures for measuring XY accuracy and repeatability when a pointer hovers at a constant distance
Electrical performance (Annex A)
- Procedures for resistance and trans‑capacitance measurement of touch sensors, measurement equipment specifications and reporting.

Practical applications and who uses it

IEC 62908‑12‑10 is intended for:

Touch display manufacturers validating sensor performance during development and production
Component and module suppliers (touch sensors, controllers)
Test laboratories and QA/validation teams performing compliance and specification tests
Systems integrators and OEMs assessing touch performance for product selection, troubleshooting or procurement
R&D teams benchmarking hover and pen input performance for new interfaces

Using the standard helps ensure consistent, repeatable measurement data for design verification, quality control, customer specifications and conformance testing.

Related standards

IEC 62908‑1‑2 (defines structural relationships for touch sensor modules) - directly referenced and required for applying IEC 62908‑12‑10.
Other parts of the IEC 62908 series covering touch and interactive displays may be relevant for broader functionality and system-level requirements.

Keywords: IEC 62908‑12‑10, touch displays, measurement methods, hovering performance, pen touch, touch sensor module, touch performance testing, electrical performance, SNR, latency.
