Abstract

The invention relates to a display system for a vehicle, comprising a display module and a connectivity module connected by an interface (4), wherein the connectivity module is arranged to transmit video data to be displayed via the interface to the display module, wherein a microprocessor arranged in the connectivity module is adapted to embed remote control data packets in the video data to be displayed thereby remotely controlling the display module. The invention also relates to a method for operating the display system.

Claims

1. A display system for a vehicle, comprising a display module and a connectivity module connected by an interface, wherein the connectivity module is arranged to transmit video data to be displayed via the interface to the display module, and wherein a microprocessor arranged in the connectivity module is adapted to embed remote control data packets in the video data to be displayed thereby remotely controlling the display module.

2. The display system according to claim 1, wherein the display module comprises circuitry for encoding and/or decoding received data and/or data to be transmitted, and wherein the display module does not comprise a microprocessor.

3. The display system according to claim 1, wherein the interface is a low voltage differential signalling interface.

4. The display system according to claim 1, wherein the remote control data packets have a serial communication format, in particular according to one of the standards UART or 12C.

5. The display system according to claim 1, wherein the display module comprises a display unit arranged as a thin film transistor display.

6. The display system according to claim 1, wherein the display module comprises an input unit for allowing a user input.

7. The display system according to claim 6, wherein the input unit is a touch panel arranged on the display unit.
