Abstract

A display panel with a first panel side and a second panel side is included in a display device. The display panel displays at least one graphic display object. The display panel includes a first layer which is a pixel matrix and a second layer which includes a plurality of predetermined primary subareas. The display device includes control circuitry to enable the displaying of the graphic display object based on a predefined display alignment in one of a first orientation and a second orientation. The control circuitry adjusts a respective light transmission to a predetermined individual degree for each of the predetermined primary subareas independent of each other based on a physical environment condition.

First claim

1 - 10 . (canceled)

11 . A display device, comprising:
a display panel with a first panel side and a second panel side, the display panel including:
a first layer on the first panel side, the first layer including a pixel matrix, wherein in a respective non-actuated state each pixel element of the pixel matrix is transparent, and
a second layer on the second panel side, the second layer including a plurality of primary subareas having an adjustable degree of light transmission; and
control circuitry configured to:
actuate a pixel element of the pixel matrix for displaying a graphic display object having a predefined display alignment,
estimate a physical environment condition based on a signal from an electronic control unit,
based on the estimated physical environment condition, enable the displaying of the graphic display object according to the predefined display alignment in one of a first orientation and a second orientation, wherein in the first orientation the graphic display object is perceivable on the first panel side in the predefined display alignment and in the second orientation the graphic display object is perceivable on the second panel side in the predefined display alignment, and
adjust a respective light transmission to a predetermined individual degree for each of a plurality of predetermined primary subareas among the plurality of primary subareas, independent of each of the respective remaining primary subareas, according to at least one of the estimated physical environment condition or whether the graphic display object is to be displayed in the first orientation or the second orientation.

12 . The display device according to claim 11 , wherein
the physical environment condition includes a driving situation of a vehicle, and the driving situation of the vehicle includes a motion phase of the vehicle and a parking phase of the vehicle.

13 . The display device according to claim 11 , wherein the physical environment condition is based on whether a presence of at least one of a user of the vehicle or a person, is detected within a predefined threshold distance from the display device, based on a signal from a proximity sensor.

14 . The display device according to claim 11 , wherein
according to the physical environment condition, information represented by the graphic display object includes at least one of a predefined text message or a predefined graphic message, and the graphic display object is displayed according to the predefined display alignment in the second orientation.

15 . The display device according to claim 14 , wherein the at least one of the predefined text message or the predefined graphic message includes a personal message referring to a predefined user, based on at least one of a signal from a face recognition sensor or a signal from a receiver which receives an identification signal from a mobile device.

16 . The display device according to claim 11 , wherein
information represented by the graphic display object includes a predefined parking time, and the graphic display object is displayed according to the predefined display alignment in the second orientation.

17 . The display device according to claim 11 , wherein
the graphic display object augments a functionality of a head light and/or a blinker of the vehicle, and the graphic display object is displayed according to the predefined display alignment in the second orientation.

18 . The display device according to claim 11 , wherein
the plurality of primary subareas are separated by a primary space between each other, the display panel further includes a third layer including a webbed structure and is configured to attenuate light in the primary space between each of the plurality of primary subareas, and the webbed structure includes an opaque material and is configured to cover the primary space between each of the plurality of primary subareas.

19 . The display device according to claim 11 , wherein
the plurality of primary subareas are separated by a primary space between each other, the display panel further includes a third layer including a plurality of secondary subareas having an adjustable degree of light transmission, the plurality of secondary subareas are separated by a secondary space between each other, and the control circuitry is configured to adjust a respective light transmission to a predetermined individual degree for each of a plurality of predetermined secondary subareas among the plurality of secondary subareas, independent of each of the respective remaining secondary subareas.

20 . A vehicle, comprising:
an electronic control unit; and a display device, including:
a display panel with a first panel side and a second panel side, the display panel including:
a first layer on the first panel side, the first layer including a pixel matrix, wherein in a respective non-actuated state each pixel element of the pixel matrix is transparent, and
a second layer on the second panel side, the second layer including a plurality of primary subareas having an adjustable degree of light transmission, and

control circuitry configured to:
actuate a pixel element of the pixel matrix for displaying a graphic display object having a predefined display alignment,
estimate a physical environment condition based on a signal from the electronic control unit,
based on the estimated physical environment condition, enable the displaying of the graphic display object according to the predefined display alignment in one of a first orientation and a second orientation, wherein in the first orientation the graphic display object is perceivable on the first panel side in the predefined display alignment and in the second orientation the graphic display object is perceivable on the second panel side in the predefined display alignment, and
adjust a respective light transmission to a predetermined individual degree for each of a plurality of predetermined primary subareas among the plurality of primary subareas, independent of each of the respective remaining primary subareas, according to at least one of the estimated physical environment condition or whether the graphic display object is to be displayed in the first orientation or the second orientation.

21 . The vehicle according to claim 20 , wherein
the physical environment condition includes a driving situation of the vehicle, when the driving situation of the vehicle is a motion phase of the vehicle, the control circuitry is configured to enable the displaying of the graphic display object according to the predefined display alignment in the first orientation such that a user disposed inside the vehicle is able to perceive the graphic display object in the predefined display alignment, and when the driving situation of the vehicle is a parking phase of the vehicle, the control circuitry is configured to enable the displaying of the graphic display object according to the predefined display alignment in the second orientation such that a person disposed outside the vehicle is able to perceive the graphic display object in the predefined display alignment.

22 . The vehicle according to claim 20 , further comprising a sensor to detect a presence of at least one of a user of the vehicle or a person, within a predefined threshold distance from the display device, and
when the control circuitry receives a signal from the sensor indicating the presence of the at least one of the user of the vehicle or the person within the predefined threshold distance from the display device, the control circuitry is configured to enable the displaying of the graphic displa
