Compare an AG anti-glare graphic overlay with an untreated option on the target display under the same conditions. Check whether reflections interfere less with viewing and whether small text and icons remain readable before selecting the surface treatment. AG and AR describe different optical treatments. A matte appearance, gloss reading or single illuminated photo is insufficient for sample approval. Record the overlay stack, display settings, ambient lighting and viewing position.
In its Potain ECS announcement dated October 14, 2026, Manitowoc describes a 13.3-inch cab touchscreen that displays equipment status and switches between information screens. The first ECS-equipped model is scheduled for launch later this year. This is a recent supplementary item, not a launch today or evidence of delivery.
If your own equipment requires operators to read status, parameters and icons, is choosing a more matte overlay window enough? This display use raises a general engineering question. The announcement does not identify a graphic overlay or AG treatment, and it provides no evidence of Baoshengda supplying components. The comparison method below is not an assessment of that crane's performance.
Identify reflection interference separately from blurred transmitted detail
Page 7 of the Elo IntelliTouch integration guide describes an AG glass finish as surface roughening that spreads specular reflections, and an AR coating as multiple coating layers that reduce reflected light intensity. These glass touchscreen terms distinguish the treatment objectives. They do not establish the same process or effect for PET or PC film, or prescribe a treatment for this project.
Pages 4 to 6 of BYK-Gardner's Transparency Measurement distinguish wide-angle scattering that affects contrast from narrow-angle scattering that affects detail recognition. They also explain that the distance between the material and viewed object affects perceived clarity. Record reflection spreading and text clarity separately when reviewing AG overlay candidates. Haze or gloss readings alone cannot determine the choice.
Compare the candidates on the same display
Keep an untreated or currently approved sample as the baseline. Candidates should use the proposed supply material and stack. Fix the display module, image, brightness setting, viewing distance and mounting position while exchanging the overlays. Do not change the surface and increase display brightness at the same time. Where the window is spaced from the display, reproduce the assembly shown in the drawing instead of holding the sample against the screen.
The following is a proposed project comparison record, not a universal test standard or industry pass limit. Select viewing positions and lighting situations for the equipment's actual use. The equipment owner must separately establish applicable requirements for safety-critical information.
| Use the same screen, image and settings. Define project criteria; do not mark untested items as passed. | ||
|---|---|---|
| Comparison situation | What to record | Decision it can support |
| Display off, lighting from the agreed direction | Position, outline and spread of the light-source reflection | Whether the candidate changes the targeted reflection, without establishing display readability |
| The same light and dark backgrounds | Blurred small text, fine lines or icons, and washed-out backgrounds | Whether reduced reflection interference comes with unacceptable detail loss |
| Actual operating position and agreed off-axis positions | Ambient light obscuring required information and differences between positions | Which candidate covers the project's required viewing range |
| Production stack and assembly gap | The same content in the specified assembly compared with temporary placement | The overlay and assembly version to which the conclusion applies, rather than a universal bare-film property |
Photos can locate reflections and problem areas, but automatic exposure, camera angle and display settings change their appearance. Preserve the observation findings and photography conditions. Two photos with different exposures cannot establish reduced glare. If quantitative results are needed, first define the applicable method, instrument and specimen conditions so the data can be compared.
Freeze the conditions with the selected surface
Specify which information must remain readable in each required image, operating position and lighting situation. Number acceptable samples and boundary samples separately. After changing the material, treatment, window stack, gap or display module, assess which comparisons need repeating. Do not transfer an old sample's AG approval to a different display.
Shenzhen Baoshengda Technology Co., Ltd.'s graphic overlay and keypad overlay information calls for reviewing material, texture, window, adhesive and assembled samples with the display module. The original Chinese product information (Chinese) is also available. Provide candidate surfaces and the same-screen comparison record, identify whether the window is only a covering component, and state which display and touch checks belong to the equipment team. A separate graphic overlay or keypad overlay does not include switch circuitry. The existing public information does not demonstrate any project's specific AG, AR or optical performance.
For instrument definitions and specimen records, see window transmittance and haze acceptance (Chinese). Measurement conditions for surface gloss are covered in gloss, texture and approved samples (Chinese). This article supports surface selection through same-screen exchanges and comparison of reflections with detail loss; it does not set universal optical limits.
When discussing samples through Baoshengda's project contact page, include the display module, actual interface images, window stack and assembly drawing, and mark where reflections occur. First define which information is readable under which conditions. Then identify that surface version in the drawing and purchase order.
