BRIEF DESCRIPTION OF THE DRAWINGS

[0024] For a better understanding of the present invention, and to show more clearly how it may be carried into effect, reference will now be made, by way of example, to the accompanying drawings, in which:

[0025] FIG. 1 shows a block diagram of a visual display system according to an arrangement; and

[0026] FIG. 2 shows a block diagram of a visual display system according to another arrangement.

DETAILED DESCRIPTION

[0027] With reference to FIG. 1, a visual display system 1 for a motor vehicle comprises an electronic display (display) 10 and a controller 20. In the arrangement depicted in FIG. 1, the controller 20 is configured to control an image displayed on the electronic display 10. The visual display system 1 may, according to an arrangement, be fitted to a vehicle, such as a commercial vehicle, a van or similar. The electronic display 10 may be located on an exterior portion of the vehicle. For example, the electronic display 10 may be attached to or integrated with the sides or the rear of the vehicle to enable logos, graphics and/or text to be displayed.

[0028] In the arrangement, according to FIG. 1, the visual display system 1 comprises one electronic display 10. However, the visual display system 1 may comprise two or more electronic displays 10. For example, a vehicle may include one electronic display 10 on either side of the vehicle and one on the rear of the vehicle. The exterior portion of the vehicle to which the electronic display 10 is attached may be any outward facing surface of the vehicle such that an image displayed on the electronic display 10 may be seen by members of the public who are outside or near the vehicle. The controller 20 may be any suitable controller operable to control one or more electronic displays 10.

[0029] With reference to FIG. 2, in an arrangement, there is provided a display (electronic display) 10, a controller 20a, a user input device 50a, such as a control console, smart phone or tablet, a vehicle locator 60a and a power source 70a. The controller 20a may comprise a time monitor 30a and an optical sensor 40a. It is to be understood that insofar as it is technically possible one or more of these features may be combined with the features of other embodiments together with or in isolation from the others shown in this arrangement.

[0030] As shown in FIG. 2, a display 10 may be located on the side of a commercial vehicle, in this case a van. The controller 20a may control the image displayed on the display 10. The controller 20a may control the image displayed on the display 10 based on a time of day and/or an ambient light level. For example, a vehicle may have set hours during which it is in use. The controller 20a may be configured to activate the display 10 during these hours and deactivate the display 10 at the end of the time during which the vehicle is in use. Alternatively, it may be desirable for the vehicle to display an image regardless of vehicle use. In an arrangement therefore, the controller 20a may activate the display 10 during specific hours of the day. For example, the controller 20a may activate the display 10 during the hours of 06:00-20:00 so that an image is displayed during this time. The controller 20a may, in combination with or independently of the above control, control the display 10 to activate or deactivate based on ambient light levels. It may be desirable for the display 10 to display an image either during the day or during the night only. Therefore, the controller may for example activate the display 10 when ambient light either reaches a sufficient level (which may indicate dawn) or drops to a sufficiently low level (which may indicate dusk). Ambient light levels may be used to ensure that the display 10 is lit up when the ambient light is not sufficient for the image displayed on the display 10 to be easily seen by a viewer. Alternatively, ambient light levels may be used to set a brightness of the image displayed on the display 10, so that during darkness (times of lower ambient light) viewers are not dazzled by the image displayed on the display 10.

[0031] With reference to the arrangement shown in FIG. 2 the controller 20a may further comprise a time monitor (timer or clock) 30a. The time monitor 30a may be capable of monitoring the time of day. The controller 20a may be configured to activate or deactivate the display 10 based on the time monitored by the time monitor 30a. The controller 20a may activate or deactivate the display 10 based on a determination whether the time of day matches a predetermined time of day. A predetermined time of day may be a specific point in time or may be a period over which the controller 20a performs control.

[0032] With reference to the arrangement shown in FIG. 2 the controller 20a may further comprise an optical sensor 40a. The optical sensor 40a may be capable of detecting ambient light levels. The optical sensor 40a may for example be a lux meter for the detection of lumen (or lumen per square meter). The controller 20a may be configured to activate or deactivate the display 10 based on the ambient light level detected by the optical sensor 40a. The controller 20a may activate or deactivate the display 10 based on whether the ambient light level matches a predetermined level of ambient light. The predetermined light level may be a specific threshold (a maximum or minimum, for example) or a range over which the display 10 may be either activated or deactivated.

[0033] The vehicle locator 60a may be a GPS (Global Positioning System) or similar and may be capable of locating the vehicle on any suitable mapping or coordinate system. The controller 20a may activate or deactivate the display 10 based on the location of the vehicle determined by the vehicle locator 60a. The controller 20a may activate or deactivate the display 10 based on a determination whether the location of the vehicle matches a predetermined location. The predetermined location may be a single point or may be an area. The predetermined location may be set according to a geo-fence. A geo-fence may be extended around an area to indicate to the controller 20a to activate or deactivate the display 10.

[0034] A geo-fence may be any suitable form of geographic boundary, representative boundary or virtual boundary and may be set for example based on user input or an anticipated route of the vehicle. The geo-fence may set a particular territory or area, wherein when the vehicle is located within the area the display 10 may be activated and display an image associated with that area. For example, the vehicle may display an advertisement relevant to a local area, but when travelling outside that area may display an alternative image or may be deactivated.

[0035] In an arrangement, the display control module 20a is configured to additionally control the image displayed on the display 10 based on input received from the user input device 50a. For example, a driver of a vehicle may determine that the image displayed, while in an appropriate area, may no longer be suitable and therefore may wish to control the display 10 to display an alternative image or to deactivate the display 10. The user input device 50a may be a mobile device capable of wireless communication with the controller 20a. For example, the mobile device may be located in the vehicle such that a user may activate or deactivate the display 10 from inside the vehicle. The user input device 50a may for example comprise a mobile phone or other hand held smart device.

[0036] In an arrangement, the display 10 may comprise a liquid crystal display (LCD) screen, a light emitting diode (LED) screen or a plasma technology screen. In an arrangement, the display 10 may comprises an e-ink or e-paper technology display. An e-ink or e-paper display may for example not use its own backlight when displaying an image and instead may use reflection of the ambient light from the surrounding environment.

[0037] In an arrangement, a vehicle may include multiple displays 10, wherein these multiple displays include at least one display such as an LED screen and another display such as an e-ink or e-paper display. In this arrangement it may be possible to reduce the energy consumption of the vehicle by switching to the e-ink or e-paper display at times of higher ambient light where backlit displays are not required. A further benefit would be to use the e-ink or e-paper display when local legislation prohibits certain forms of light emission from moving vehicles.
