| Simultaneous touch points | 10 points | Place and move ten independent contacts simultaneously; check that every contact is reported without drops or unintended merging. | Touch-controller specification and a live demonstration using the intended operating system. |
| Touch response time | Under 10 ms | Measure input-to-report latency under a documented test setup. Confirm whether the quoted figure is typical or maximum and how it is measured. | Test method, measurement conditions, and a report identifying the tested panel and controller configuration. |
| Touch accuracy | Within ±2 mm | Tap calibration points distributed across the active area, including near the corners, and compare reported coordinates with actual contact positions. | Accuracy test results covering the full active area and the specified cover glass. |
| Coordinate stability | No visible jitter during a stationary touch | Hold a contact still at the center and near the edges; observe coordinate movement and cursor stability. | Recorded test output or demonstration using the production-intent touch assembly. |
| Edge and corner performance | Consistent detection across the active area | Repeat taps and drags along all four edges and through each corner; check for dead zones and distorted tracking. | Area-coverage test results for the final bezel, panel, and cover-glass design. |
| Tracking continuity | Continuous tracking during slow and fast drags | Draw straight lines, curves, and diagonal strokes at different speeds; look for breaks, jumps, or unintended extra contacts. | Demonstration video or test record using the intended firmware and interface. |
| Palm and accidental-touch handling | Stable operation for the intended use case | Test hand placement and incidental contact around the display while performing normal touch gestures. | Documented settings or configuration options for palm rejection, if required by the application. |
| Environmental robustness | Performance maintained under specified conditions | Test touch operation at the temperature and humidity limits required for the product; check for false touches and missed inputs. | Operating-condition specifications and test reports for the relevant configuration. |
| Interface and operating-system support | Compatible with the required host interface and OS | Connect the monitor to the target system and verify touch input, gestures, and wake behavior over the intended connection. | Interface details, supported operating systems, and a compatibility demonstration. |
| Production consistency | Performance verified on production-intent units | Repeat the agreed touch tests on samples from a production-representative build rather than relying only on an engineering prototype. | Inspection plan, sample test records, and the factory’s process for handling failed units. |
