Smartphones, tablets, televisions: touch displays are ubiquitous and are increasingly being used in modern vehicles - whether for buttonless operation of the air conditioning or infotainment system. In contrast to consumer electronics, these functions have to face special challenges in vehicles: Strong vibrations, changing temperatures and electromagnetic fields are the rule in road traffic. To ensure that drivers can enjoy the benefits of touch displays not only at home but also in their cars, the technology must therefore be adapted to the requirements of the automotive industry. This is achieved, for example, by integrating state-of-the-art technologies with TDDI or OLED components, but also by means of an extensive testing and validation process with regard to resistance and function. In this way, it can be ensured that the driving experience is actually enhanced and not diminished by advanced touch displays.
Capacitive sensors are used for touch displays due to their higher reliability and wider range of functions. While panels in household electronics are becoming thinner and lighter, this poses a greater problem for vehicles. There, the sensitive sensor technology is subject to stricter requirements in terms of service life and environmental influences, which is why more robust displays have been developed - but at the expense of lightweight construction. Nevertheless, precise sensor technology is still necessary in vehicles in order to transport the accustomed comfort into the vehicle of tomorrow.
While high rigidity of components is also important, touch displays should still be flexible enough in an accident to reduce the risk of injury in a collision. It is therefore important to protect the sensors and the driver on the one hand, but also to bring familiar features into the passenger cell on the other.
Evolution of Displays - Outcell, Oncell, Incell
This is achieved by integrating the individual components into the display. When the electronics are applied to the outer layers (Outcell Technology), they are more exposed to temperature
