display / touch / bonding solutions
Fanless cooling in enclosed vehicle displays uses passive thermal designs like aluminum back-housings as heat radiators, thermal pads, graphite sheets, and OCA optical bonding to dissipate TFT LCD heat without fans. This ensures reliable operation from -30°C to +85°C in sealed dashboards, as offered in CDTech's IATF16949-certified automotive panels.

Enclosed vehicle displays face high ambient temperatures up to 85°C, intense sunlight requiring 1000 nits brightness, and sealed housings that trap heat from TFT LCD backlights. Fans risk vibration, dust ingress, and failure in automotive settings, making passive solutions essential for zero-defect reliability.
Aluminum back-housings with fins conduct heat directly from the TFT LCD backlight and electronics, functioning as primary heatsinks. Thermal interface materials like pads and graphite sheets enhance transfer efficiency. CDTech customizes these for 3.6" to 12.8" vehicle panels, optimizing via simulations for compact enclosures.
| Material | Thermal Conductivity (W/mK) | Cost | Weight | Automotive Suitability |
|---|---|---|---|---|
| Aluminum | 200-250 | Low | Medium | High (IATF16949 standard) |
| Copper | 400 | High | High | Medium (weight penalty) |
| Magnesium Alloy | 150 | Medium | Low | High (lightweight vehicles) |
OCA optical bonding eliminates air gaps between touch panels and LCDs, reducing trapped heat and reflections for better sunlight readability at 850-1000 nits. It pairs with back-housing radiators to minimize thermal buildup in high-brightness automotive displays like CDTech's S101HWX53EP-FC47-AG.
IATF16949 certification guarantees vibration-proof, zero-defect performance across -30°C to +85°C in enclosed dashboards. CDTech's 10,000㎡ factory with 3,500㎡ dust-free workshop supports rapid prototyping of automotive display heatsinks, proven through 13+ years of global exports.
"For our 12.3-inch IPS panel S123BWU11EP with 1920×720 resolution and 950 nits brightness operating at -30°C~+80°C, we designed an aluminum back-housing radiator with optimized fins that reduced hotspot temperatures by integrating graphite sheets and OCA bonding. This fanless solution ensures no overheating in sealed vehicle consoles," says CDTech's senior thermal engineer.
"Another case involved the 10.1-inch S101HWX53EP-FC47-AG touch display with LVDS interface and CTP. Our IATF16949-compliant design used direct-contact aluminum housings, cutting thermal resistance by 25% for reliable 850 nits performance. With ISO9001, ISO14001, ISO13485 certifications and our zero-defect policy, we deliver custom wide-temp solutions from our Shenzhen facility."
