Confirm sunlight readability with application-specific samples. |
| 2 | Verify interface compatibility | Supplier Profile B | 10.1-inch IPS LCD; 1,200 × 800 resolution; MIPI DSI and LVDS options; 5-point touch | MIPI DSI signal-integrity test passed at the specified cable length; touch response remained below ни? 100 ms in sample testing | US$112–138 at 500 units | 8–10 weeks; MOQ 50 units | Strong integration flexibility. Request complete pin mapping, timing tables, backlight specifications, and tested cable assemblies before design freeze. |
| 3 | Compare optical performance | Supplier Profile C | 5.5-inch AMOLED; 800 × 480 resolution; 800 cd/m² brightness; 2,000:1 typical contrast ratio | Color uniformity measured within ±10% across the active area; viewing angle exceeded 160° horizontally in laboratory testing | US$64–82 at 1,000 units | 7–9 weeks; MOQ 200 units | Suitable where contrast and wide viewing angles matter. Check image-retention requirements, brightness aging, and power consumption during long static-screen operation. |
| 4 | Demand reliability and environmental testing | Supplier Profile D | 8-inch sunlight-readable LCD; 1,500 cd/m² brightness; optical bonding; IP65 front surface | Thermal cycling from -30°C to 80°C completed for 100 cycles; vibration screening performed to the agreed equipment profile | US$145–178 at 500 units | 10–12 weeks; MOQ 100 units | Best fit for mobile, outdoor, and transportation equipment. Require formal test reports, sealing details, and confirmation that the complete assembly—not only the panel—meets the target rating. |
| 5 | Evaluate total cost, not only unit price | Supplier Profile E | 4.3-inch TFT LCD; 480 × 272 resolution; 450 cd/m² brightness; standard controller board included | Functional inspection coverage listed at 100%; sample power consumption measured at 2.8 W with backlight enabled | US$29–41 at 1,000 units | 5–7 weeks; MOQ 500 units | Lowest estimated purchase cost, but confirm tooling, cables, controller firmware, packaging, shipping, inspection, and warranty expenses before approval. |
| 6 | Test touch performance with real gloves and contaminants | Supplier Profile F | 12.1-inch projected-capacitive touch display; 1,000 cd/m² brightness; glove-support firmware | Successful touch operation with 1.5 mm work gloves in sample testing; wet-finger performance requires application-specific validation | US$168–215 at 300 units | 9–11 weeks; MOQ 50 units | Appropriate for operator interfaces. Freeze the touch controller, cover-glass thickness, glove type, and gesture requirements before production release. |
| 7 | Confirm lifecycle and after-sales support | Supplier Profile G | 7-inch LCD module; 1,000 × 600 resolution; 700 cd/m² brightness; custom bezel and connector option | Pilot units passed 72-hour burn-in and basic electrical inspection; formal change-notification process documented | US$86–119 at 500 units | 8–10 weeks; MOQ 100 units | Strongest documented support package: five-year availability target, 12-month standard warranty, engineering change notices, and second-source planning recommended. |
