A very frustrating problem is that the touch screen control device is always missed and economy cars. However, Continental announced a allows users to implement multi-touch capabilities on any car "infrared light curtain" (infrared curtain) system that allows inexpensive models see hope.
Components of the infrared light curtain system is not complicated, it means a box, the box adjacent sides of a series of LED lights, the other two sides are a series of photodiodes. Each LED will emit a beam of infrared light, and is located opposite the parallel position of the photodiode receives infrared and converts it into an electric signal.
It is reported that this box will be embedded in the outer piece of the LCD display, providing no different from ordinary capacitive touch screen control function. When the infrared beam network users through LED light emitted by touching the screen, under the influence of a finger, the corresponding photodiode can not receive the infrared beam to stop sending signals. The influence caused by a photodiode, the system can determine the user real-time position of the finger corresponding to the control button.
In fact, an earlier version of the infrared light curtain system has achieved the above functions, improved later, the system can recognize touch gestures such as zoom in and out. It is worth mentioning that, even if the user's hand wearing gloves is not capacitive, the system can work, from this point of view, the new system is superior to the traditional touch screen.
Continental is currently being carried out to optimize the thickness of the framework is expected to be officially put into operation in 2017.
