Samvardhana Motherson International has filed a patent for a display system for vehicles. The system includes a camera module to capture the surroundings, a display unit with multiple viewing angles, and a filter that can selectively allow certain viewing angles. A processing unit controls the filter’s enabled or disabled state, allowing the display of the captured field-of-view in specific or all viewing angles. The patent also covers the vehicle equipped with this display system and the method of operating it.

A recently filed patent (Publication Number: US20230311773A1) describes a display system for vehicles that aims to enhance the driver's field of view. The system includes a camera module that captures the scenery around the vehicle and a display unit that shows the captured field of view (FOV). The display unit has multiple viewing angles, and a filter is positioned on or over the display unit to selectively allow at least one viewing angle. The filter can be operated in an enabled state or a disabled state.

When the filter is in the enabled state, it allows the exhibition of the FOV in the selected viewing angle, which is a subset of the available viewing angles. On the other hand, when the filter is in the disabled state, it allows the exhibition of the FOV in all of the available viewing angles. This feature provides flexibility for the driver to choose the desired viewing angle based on their preferences or specific driving conditions.

The filter in the display system can be comprised of multiple translucent ribs that extend from the display unit at specific angles. These ribs can switch between transparent, translucent, and opaque states. The light transmission properties of the ribs can be altered by applying voltage, light, or heat. The processing unit of the system can electronically enable or disable the ribs, allowing them to define the selected viewing angle when enabled.

The display system also includes a driver detection system, which can consist of a camera focused on the driver, a proximity sensor, a time of flight (TOF) sensor, or a sensor integrated into the driver's seat. This system can detect real-time information about the driver's seating position, head position, eye position, and viewing direction. The processing unit can use this information to determine a driver-centric viewing angle and selectively enable the ribs based on the driver's input.

The patent also mentions the possibility of an input module for the driver to input a custom viewing angle, allowing further customization of the display system.

Overall, this display system patent aims to improve the driver's field of view by providing flexibility in selecting viewing angles and incorporating driver detection technology. It has the potential to enhance safety and driving experience in vehicles.
