In many display projects for the industrial, medical and consumer markets, it has become common to incorporate sensors within displays.
A widespread application is to mount optical sensors for brightness measurement behind a transparent or slightly tinted area of the front glass. The result of the brightness measurement is used to adjust the display's brightness to the environment, for example. Proximity sensors underneath the front glass also ensure that the display only turns on when an operation is desired. Gesture control and general image recognition are further possibilities to equip displays accordingly.
A temperature sensor on the display can also be of great importance in certain projects. Especially when the display has to switch off so that the maximum operating temperature is not exceeded, a direct temperature measurement at the display is required.
To make communication with the sensor interfaces as simple as possible, it is advisable to integrate the sensor interface into the already existing interface environment. This way, the I²C interface of the touchscreen can be used together with the I²C interface of the sensor without having to change the pinout of the display module.
