How to conquer bumps and temperature differences with car mounted outdoor touch screens?

Whether it's electronic bus stop signs, entertainment systems for long-distance buses, or monitoring terminals for construction vehicles, in car PCAP touch screens are increasingly becoming a mobile "smart window". However, vehicles in motion pose unique challenges to the PCAP touch screens: continuous vibrations, drastic temperature changes, and multi angle lighting.
 

Special "exam questions" for in car environments:
Vibration and impact: Bumps, sudden braking, and bumps during vehicle operation may cause damage to the internal structure of the PCAP touch screens.
 

Extreme temperature difference: In summer, the dashboard temperature can reach over 70 ° C under direct sunlight, while in winter it may drop to below zero.
Complex lighting: Direct sunlight, side lighting, and constantly changing backlight angles affect the visual effect.
Compact Space: Requires lightweight design to save valuable interior space.
 

The response of Xinlilai Touch:
1. Strengthening structural design: From the reinforcement and routing of FPC cables, adhesive fixation of key components, to the seismic buffering design of the overall structure, we comprehensively enhance the mechanical strength of the product to ensure that it can withstand long-term vibration fatigue and instantaneous impact, in compliance with automotive industry standards (such as ISO 16750).
 

2. Wide temperature stability guarantee: The core components (LCD, polarizer, driver IC, touch sensor) are all selected from industrial grade wide temperature models. In terms of production process, special optical adhesive (OCA/OCA) is used, which maintains stable temperature resistance and bonding strength under cold and hot cycles, preventing delamination and foaming.
 

3. Optical performance optimization: Equipped with high brightness backlight module and wide viewing angle technology (such as IPS/FFS), passengers can see the content clearly from different seat angles. Surface anti glare (AG) treatment is standard, effectively suppressing the "white haze" caused by sunlight reflection.
 

4. Reliable touch experience: Optimize touch algorithms to resist accidental touches caused by vibration. Surface oil repellent layer treatment facilitates the cleaning of fingerprints and oil stains, keeping the PCAP touch screens constantly new.
 

As a leading factory specializing in PCAP touch screens technology, we provide stable and reliable in car display solutions for numerous bus and special vehicle manufacturers. From material selection to process control, every step is aimed at ensuring that this' mobile screen 'remains clear, sensitive, and durable through wind and rain.
