Capacitive touch screen requirement depends on the installation location (front or back) of the end products in the vehicle and the corollary devices. If end products are installed in front of the vehicle, in-vehicle control system, for example, requirements are relatively higher because they must meet relevant certification and explosion proof. Requirements are lower for end products located at the back of the vehicle such as car-borne navigation, audio-visual equipment and intelligent parking systems, intelligent traffic control terminals,etc. Antiriot, earthquake-proof, visibility in the sun and anti-interference are generally concerned about for terminals in this field, so G + G structure is generally recommended and G + F (F) structure are likely to be considered for breech-loading products that are high volume and cost sensitive.
Case Introduction:
front loading vehicle control system
Application environment and features:
1, mainly used in automotive control meter,so need to meet good visibility in the sun ;
2, requires explosion-proof seismic rhetorical vehicle certification;
3, require stronger anti-interference.
Touch panel solution:
1. G +G structure, thick tempered glass cover with surface AG processed;
2. Cypress program for screen size below 12.1 inch and EETI program for screen size above 12.1 inch with good anti-interference performance;
3. Considering the seismic explosion proof and wide temperature change, TP and TFT overall module joint assembly is recommended.
