Abstract
A TFT display screen device includes at least one active zone whose pixels are used for the display of an instrument cluster and the display of one or more warning or alarm), optionally icons inlaid in the instrument cluster. The screen also includes at least one dead zone not visible to the user. At least one dead zone is provided-with at least one light sensor and at least one control pixel which is activated when the single icon or at least one icon with which it is associated, is displayed in the active zone of the screen. The sensor is adapted to detect the activation of said at least one control pixel and to deliver a signal.
Claims21
A vehicle dashboard screen comprising:
- a thin-film transistor (TFT) display screen, wherein the display screen includes:
- at least one active zone of the display screen, the at least one active zone including pixels configured to generate and display one or more of an instrument cluster, a map and one or more alarm icons, and
- at least one dead zone of the display screen, wherein the at least one dead zone includes at least one control pixel;
- a processing unit in communication with the at least one active zone of the display screen and the at least one dead zone of the display screen for administering operation of the display screen;
- and
- at least one light sensor in communication with the processing unit and disposed adjacent the at least one control pixel on the at least one dead zone of the display screen to detect activation of the at least one control pixel,
- wherein the processing unit manages operation of the display screen in response to the at least one light sensor transmitting a signal to the processing unit indicative of the activation state of the at least one control pixel in the at least one dead zone of the display screen.

A vehicle dashboard screen comprising:
- a housing including a front frame and a rear closure plate cooperating with the front frame;
- a thin-film transistor (TFT) display screen, wherein the display screen includes:
- at least one active zone of the display screen, the at least one active zone including pixels configured to generate and display one or more of an instrument cluster, a map and one or more alarm icons, and
- at least one dead zone of the display screen, wherein the at least one dead zone includes at least one control pixel;
- a processing unit in communication with the at least one active zone of the display screen and the at least one dead zone of the display screen for administering operation of the display screen;
- and
- at least one light sensor in communication with the processing unit and disposed adjacent the at least one control pixel on the at least one dead zone of the display screen to detect activation of the at least one control pixel,
- wherein the processing unit manages operation of the display screen in response to the at least one light sensor transmitting a signal to the processing unit indicative of the activation state of the at least one control pixel in the at least one dead zone of the display screen.

A method of managing operation of a vehicle dashboard screen, the method comprising:
- providing a thin-film transistor (TFT) display screen, wherein the display screen includes:
- at least one active zone of the display screen, the at least one active zone including pixels configured to generate and display one or more of an instrument cluster, a map and one or more alarm icons, and
- at least one dead zone of the display screen, wherein the at least one dead zone includes at least one control pixel;
- providing a processing unit in communication with the at least one active zone of the display screen and the at least one dead zone of the display screen for administering operation of the display screen;
- providing at least one light sensor in communication with the processing unit and disposed adjacent the at least one control pixel on the at least one dead zone of the display screen;
- activating the at least one control pixel in the at least one dead zone of the display screen in response to activation of one or more of the alarm icons on the at least one active zone of the display screen;
- detecting activation, with the at least one light sensor, of the at least one control pixel;
- transmitting a signal, with the at least one light sensor, to the processing unit indicative of the activation state of the at least one control pixel in the at least one dead zone of the display screen;
- and
- operating, with the processing unit, the display screen in response to the at least one light sensor detecting the activation state of the at least one control pixel in the at least one dead zone of the display screen.
