I. Display Performance Evaluation

Resolution and Clarity

Prioritize screens with 2K/4K resolution to ensure that images and text are displayed sharply without jagged edges (e.g., in dental imaging and 3D modeling scenarios)Check for dead pixels (bright or dark spots) using a solid color background (white, red, green, blue). The total number of dead pixels on a single screen should be ≤5 with no obvious clustering.

Color Accuracy

The screen should cover at least 100% sRGB color gamut or higher standards (such as DCI-P3) to prevent color distortion in details like tooth color and soft tissueObserve whether color transitions are smooth and use professional software (e.g., SpyderX) to test color gradation performance.

Brightness and Contrast

The base brightness should be ≥300 nits. In strong light conditions, an anti-glare coating is recommended to reduce reflective interference.The contrast ratio should be ≥1000:1 to ensure deep blacks and pure whites (e.g., for the grayscale details in X-ray images).

II. Touch Performance Testing

Touch Precision and Response Speed

The error should be ≤±1mm. Verify click accuracy using a touch calibration tool (e.g., Windows Tablet Settings).The response speed should be ≤5ms to avoid delays in drag operations (e.g., lag when rotating a 3D model).

Multi-Touch Support

The device should support at least 10-point touch to meet the needs of multi-user collaboration or complex gesture operations (e.g., zooming and annotating in educational settings).

III. Durability and Environmental Adaptability

Protection Level and Material

For medical or industrial settings, IP65-level water and dust resistance is required to withstand splashes and disinfectant sprays.The screen surface should be made of scratch-resistant tempered glass. Check for scratches and cracks using a microscope.Environmental Stability Testing

Test the device in high-temperature (40°C), low-temperature (-10°C), and high-humidity (85%) environments to observe whether there is any touch drift or display anomalies.

IV. Appearance and Craftsmanship Inspection

Screen Uniformity

In a dark room, check for light leakage. The width of the edge halo should be ≤2cm (slight light leakage is allowed for IPS screens).Inspect the backlight uniformity in a full black screen to avoid local whitening or dark spots.

Structural Design

The bezel seam should be ≤1.8mm to ensure no touch interruption at the edges.The screen should be securely connected to the body, with flexible and stable opening and closing angles, and no loose or noisy parts.

V. Quick Testing Tools Recommendation

By conducting these multi-dimensional tests, you can comprehensively evaluate the display quality, touch performance, and durability of the all-in-one touchscreen device, meeting the professional requirements of medical, educational, and other specialized scenarios.
