Alternatively, or in addition, the image data DIMG may be stored remotely and transmitted to the controller 63 as an input signal. The image data in the present embodiment represents an animated graphic. The animated graphic may be pre-rendered or may be generated dynamically. The animated graphic in the present embodiment comprises a salutation or message. The animated graphic may be customisable, for example to display a personalised message.

The controller 63 is configured to control the dynamic display 61 to display the dynamic image only when the first door 19-1 is in the open position. In the present embodiment, the controller 63 is configured to control the dynamic display 61 in dependence on the first door position signal 75. The controller 63 controls the dynamic display 61 to display the dynamic image when the first door position signal 75 indicates that the first door 19-1 is in the open position. At least in certain embodiments, the dynamic display 61 can be selectively activated and deactivated. The dynamic display 61 is switched OFF or is configured in a low power mode (also known as a sleep or standby mode) when deactivated. The dynamic display 61 is switched ON or is configured in an operating power mode when activated. The controller 63 is configured to activate the dynamic display 61 in dependence on a determination that the first door 19-1 is in the open position; and to de-activate the dynamic display 61 in dependence on a determination that the first door 19-1 is in the closed position.

The operation of the dynamic display unit 39 will now be described with reference a first block diagram 100 shown in Figure 7. The first door 19-1 is initially in a closed position (BLOCK 105). The dynamic display 61 is hidden from view when the first door 19-1 is in the closed position. The first door position sensor 77 senses that the first door 19-1 is in the closed position and outputs a first door position signal 75 indicating that the first door 19-1 is closed (BLOCK 110). The controller 63 receives the first door position signal 75 and configures the dynamic display 61 in the low power mode (BLOCK 115). The first door 19-1 is then opened. The dynamic display 61 is revealed when the first door 19-1 is moved from the closed position to the open position. The whole of the dynamic display 61 is visible when the first door 19-1 is in the open position. The first door position sensor 77 senses that the first door 19-1 is in the open position and outputs a first door position signal 75 indicating that the first door 19-1 is open (BLOCK 120). The controller 63 receives the first door position signal 75 and activates the dynamic display 61 (BLOCK 125). The controller 63 wakes the dynamic display 61 from the low power mode in dependence on the first door position signal 75 (BLOCK 130). The controller 63 outputs the display control signal 79 to the dynamic display 61 (BLOCK 135). The display control signal 79 comprises the image data DI MG read from the memory device 67. The dynamic display 61 displays the animated graphic represented by the image data (BLOCK 140). In the present embodiment, the image data comprises a graphical representation of a salutation or a message for the user. The first door 19-1 is subsequently moved from the open position to the closed position (BLOCK 145). The first door position sensor 77 senses that the first door 19-1 is in the closed position and outputs a first door position signal 75 indicating that the first door 19-1 is closed (BLOCK 150).

The controller 63 receives the first door position signal 75 and switches the dynamic display 61 to the low power mode to conserve power (BLOCK 155).

The operation of the dynamic display unit 39 has been described with reference to the display of an animated graphic. The dynamic display unit 39 can be used to display graphical information, for example to indicate a vehicle operating parameter. As outlined above, the controller 63 is connected to the communication network on the vehicle 1. The controller 63 may be configured to read a vehicle operating parameter from the communication network and to control the dynamic display 61 to display the vehicle operating parameter. The vehicle operating parameter may, for example, be determined in dependence on one or more signal S-n received from a vehicle sensor VS-n. By way of example, the vehicle sensor VS-n may comprise a proximity sensor VS-1 for detecting the presence of an obstacle proximal to the vehicle 1. The dynamic display unit 39 may be configured to display a notification to alert an occupant to the presence of the obstacle. The notification may, for example, alert the occupant to the presence of an obstacle that will obstruct the opening of the first door 19-1. Alternatively, or in addition, the dynamic display unit 39 may display a video image captured by one or more imaging sensor VS-2 provided on the vehicle 1. The video image may, for example, provide a real-time video image of a view in front of or behind the vehicle 1. Alternatively, or in addition, the dynamic display unit 39 may display a composite image generated by combining the images received from more than one imaging sensor VS-2. The composite image may, for example, comprise a bird's-eye view representation of a region adjacent to the vehicle 1.

The image displayed on the dynamic display unit 39 could be customized. For example, the image may be tailored or customized for each of a plurality of users. Alternatively, or in addition, the dynamic display unit 39 may be configured to control the dynamic display 61 to display different image(s) depending on whether the user is entering or exiting the vehicle 1.

The mounting of the vehicle-body frame trim assembly 35-1 has been described with reference to the first door 19-1 which provides access to the front of the cabin 7. Alternatively, or in addition, the vehicle-body frame trim assembly 35-1 may associated with the second door 19-2. Alternatively, or in addition, the vehicle-body frame trim assembly 35-3, 35-4 may associated with one or more of the third and fourth doors 19-3, 19-4 which provide access to the rear of the cabin 70.
