Abstract
A method of diagnosing an electronic display device (1) having a screen (3) and a graphics memory (2) in which image data (14), of an image displayed or to be displayed on the screen (3), are one of stored or changed. A measured value (15) characterizes a current consumption or the change in current consumption of the screen (3) or display device (1) while a reference value (16) characterizes the current consumption or the change in current consumption of the screen (3) or display device (1) on the basis of the image data (14) or the change in image data (14). The method compares the reference value (16) to the measured value (15) to determine any malfunction or error in the electronic display device (1).

9. A method of diagnosing an electronic display device (1) having a screen (3) and a graphics memory (2) in which image data (14), either a displayed image or an image to be displayed on the screen (3), being one of stored and changed, the method comprising the steps of:
-
measuring a measured value characterizing either current consumption or change in current consumption of either the screen (3) or the display device (1); determining, on a basis of either the image data (14) or a change in the image data (14), a reference value (16) characterizing one of the current consumption and the change in current consumption of either the screen (3) or the display device (1); and comparing the reference value (16) to the measured value (15). - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A device for diagnosing an electronic display device (1), the device comprising:
-
the electronic display device (1) having a screen (3) and a graphics memory (2) in which image data (14) of at least one of a displayed image and an image to be displayed on the display device (1), being one of stored and changed; a current-measuring device (6, 7) for measures a measured value characterizing at least one of a current consumption and a change in a current consumption of at least one of the screen (3) and display device (1); and an evaluation device (8) for determining a reference value (16) characterizing at least one of the current consumption and the change in a current consumption of at least one of the screen (3) and the display device (1) on a basis of the image data (14) or the change in the image data (14), and comparison of the reference value (16) to the measured value (15).

17. A method of diagnosing an electronic display device (1) having a screen (3) and a graphics memory (2) for storing image data (14) of at least one of a displayed image and an image to be displayed on the screen (3), the method comprising the steps of:
-
measuring a measured value of at least one of a current consumption and a change in current consumption of at least one of the screen (3) and the display device (1); determining a reference value (16) of at least one of the current consumption and the change in the current consumption of at least one of the screen (3) and display device (1) from one of the image data (14) and a change in the image data (14); comparing the reference value (16) to the measured value (15); and recognizing an error in the electronic display device (1) if the measured value (15) is outside a range of the reference value (16).
