Abstract
Embodiments are disclosed for a method for controlling backlighting of a heads up display of a vehicle. In one example, the method includes adjusting different backlighting regions of the heads up display differently without analyzing a displayed image. In another example, different backlighting regions include a first region and a second region that do not overlap, and adjusting is based on a vehicle operating parameter, user input, and/or a vehicle mode. In another example, backlighting is controlled via a backlight with an array of light emitting elements, and regions include separate adjacent groups of light emitting elements.
Claims19
A method for controlling backlighting of a heads up display of a vehicle, comprising:
- receiving information about a displayed image;
- adjusting different backlighting regions of the heads up display differently based on the information without analyzing pixels or groups of pixels of the displayed image,
- wherein the information comprises one or more of a type, a size, and a location of the displayed image;
- and
- dividing a backlight into a plurality of non-overlapping regions based on vehicle operating conditions and/or user input during vehicle operation,
- wherein the adjusting includes varying a power level to each of the plurality of non-overlapping regions responsive to vehicle operating conditions and/or user input,
- wherein the plurality of non-overlapping regions includes during a first set of conditions, dividing the backlight into at least a first region, a second region, and a third region, with power set for the first region, the second region, and the third region at a first level, a second level, and a third level, respectively;
- and during a second set of conditions different from the first, setting the power for the first region, the second region, and the third region at a fourth level, a fifth level, and a sixth level, respectively.
A system for a vehicle, comprising:
- an image generating unit;
- a backlight coupled with the image generating unit to illuminate an image for display in a heads up display of the vehicle;
- and
- a control system with a processor and instructions that, when executed comprise:
- receiving information about a displayed image;
- powering different backlighting regions of the backlight to generate different levels of light based on the received information without analyzing pixels or groups of pixels of the image, wherein the information comprises one or more of a type, a size, and a location of the displayed image;
- and
- dividing a backlight into a plurality of non-overlapping regions based on vehicle operating conditions and/or user input during vehicle operation, wherein the powering includes varying a power level to each of the plurality of non-overlapping regions responsive to vehicle operating conditions and/or user input, wherein the plurality of non-overlapping regions includes during a first set of conditions, dividing the backlight into at least a first region, a second region, and a third region, with power set for the first region, the second region, and the third region at a first level, a second level, and a third level, respectively;
- and during a second set of conditions different from the first, setting the power for the first region, the second region, and the third region at a fourth level, a fifth level, and a sixth level, respectively.
A method for controlling backlighting of a heads up display of a vehicle, comprising:
- dividing an array of light sources of a backlight into a plurality of different backlighting regions based on a vehicle operating condition;
- powering each of the plurality of different backlighting regions with a different power level, each of the different power levels adjusted responsive to the vehicle operating condition without analyzing pixels or groups of pixels of a displayed image on the heads up display,
- wherein the vehicle operating condition comprises one or more real-time user inputs and vehicle operating parameters categorized by type, size, and region of display;
- and
- dividing a backlight into a plurality of non-overlapping regions based on vehicle operating conditions and/or user input during vehicle operation, wherein the adjusting includes varying a power level to each of the plurality of non-overlapping regions responsive to vehicle operating conditions and/or user input,
- wherein the plurality of non-overlapping regions includes during a first set of conditions, dividing the backlight into at least a first region, a second region, and a third region, with power set for the first region, the second region, and the third region at a first level, a second level, and a third level, respectively;
- and during a second set of conditions different from the first, setting the power for the first region, the second region, and the third region at a fourth level, a fifth level, and a sixth level, respectively.
