Abstract
It is an object to provide a driving support system and a display device suitable for the driving support system. According to the driving support system, change in driver's mental and physical conditions can be caught instantaneously and a warning light emission display is given within the forward sight of the driver in order to call the driver's attention. A light emitting device of the driving support system can display a far side of the display. A display may be switched between a transmission mode and a non-transmission mode by adjusting a movable polarizer.
Claims16
A driving support system comprising:
- a camera for shooting a forward scene or a peripheral scene outside a vehicle;
- a means for detecting a living body information of a driver;
- a judging means for judging if there is any vehicle ahead, an obstruction, or the living body information of the driver;
- and
- a light emitting device for displaying data on a drive of the vehicle or a warning data based on the judging means, the light emitting device comprising a first polarizer on a first surface of the light emitting device and a second polarizer, which is removable, near a second surface of the light emitting device,
- wherein the light emitting device switches between a display superposed with the forward scene outside the vehicle in case of displaying data on the drive of the vehicle and a display without the forward scene outside the vehicle, which is shielded using the second polarizer, in case of displaying the warning data.

- a light emitting device for displaying data on a drive of the vehicle or a warning data based on the judging means, the light emitting device comprising a first polarizer on a first surface of the light emitting device and a second polarizer, which is removable, near a second surface of the light emitting device;
- and
- a surrounding circumstance detecting means for detecting a surrounding circumstance of a vehicle,
- wherein a display superposed with the forward scene outside the vehicle in a transmission mode and a display without the forward scene outside the vehicle in a non-transmission mode are switched automatically using the second polarizer depending on a surrounding circumstance obtained by the surrounding circumstance detecting means.
