Abstract

An example display device includes a panel and a controller to define a boundary between a first region of an input layer of the panel and a second region of the input layer of the panel. The example controller disables digital ink input for the first region when the first region is designated for video output and the controller enables digital ink input for the second region when the second region is designated for receiving digital ink input.

First claim

What is claimed is:

1. A display device comprising:
a panel including:
an image output layer to output visual content; and
an input layer to receive digital ink input; and

a controller to:
define a boundary between a first region of the input layer of the panel and a second region of the input layer of the panel based on an identifier associated with a user preference;
disable digital ink input for the first region when the first region is designated for video output; and
enable digital ink input for the second region when the second region is designated for receiving digital ink input.

2. The display device of claim 1 , wherein:
the boundary is adjustable based on touch input received by the input layer when the display device is in zone edit mode.

3. The display device of claim 1 , wherein:
the input layer of the panel is to receive touch input; and
the controller is to disable touch input for the second region and enable touch input for the first region.

4. The display device of claim 1 , wherein:
the second region is to display a scaled view of an image of the first region when the display device is in direct ink mode; and
the second region is to display a navigation pattern when the display device is in indirect ink mode.

5. The display device of claim 1 , wherein:
the user preference is a default corresponding to a physical location on the panel where the image output layer folds.

6. A non-transitory computer-readable storage medium (NTCRSM) comprising a set of instructions executable by a processor resource to:
determine a first boundary between a first region of an input layer of a display panel and a second region of the input layer of the display panel;
determine a second boundary between the second region of the input layer and a third region of the input layer of the display panel;
disregard digital ink input within the first region when the first region is designated for video output;
enable touch input and digital ink input within the second region when a toolbar is displayed in the second region; and
enable digital ink input within the third region when the third region is designated for receiving digital ink input.

7. The NTCRSM of claim 6 , wherein the set of instructions is executable by the processor resource to:
adjust the first boundary and the second boundary based on touch input on the input layer of the display panel corresponding to movement of the toolbar displayed on the display panel.

8. The NTCRSM of claim 6 , wherein the set of instructions is executable by the processor resource to:
cause a video processor to scale video from a host compute device to the first region at a first set of visual dimensions; and
cause, when the third region is selected for direct ink mode, the video processor to scale video from the host compute device to the third region at a second set of visual dimensions different from the first set of visual dimensions.

9. The NTCRSM of claim 6 , wherein the set of instructions is executable by the processor resource to:
generate, via the video processor, a trace image using an edge detection operation;
cause the video processor to adjust visual dimensions of the first region or the second region based on a signal corresponding to gesture input received at a location of the input layer of the display panel;
cause, by the video processor, the trace image and a navigation pattern to display at the third region based on the adjusted visual dimensions and a user-defined percentage of opacity; and
restrict, via the video processor, digital ink input to an edge of the trace image by disregarding digital ink input outside of the edge of the trace image.

10. The NTCRSM of claim 6 , wherein the set of instructions is executable by the processor resource to:
cause a video processor to provide ink input data to a host compute device based on digital ink input received within the third region of the input layer of the display panel; and
cause the video processor to provide image data corresponding to the input layer of the display panel at the third region to an auxiliary display device coupled to the host compute device, the auxiliary display device to generate a visual representation corresponding to video output associated with visual output displayed at the first region of the display panel.

11. A method of defining display regions, the method comprising:
providing, via a video processor, image data to an input/output (I/O) port, the image data having a first set of visual dimensions;
receiving, via the video processor, input corresponding to a boundary change between a first region of a display device and a second region of the display device, the first region of the display device to output the image data at a second set of visual dimensions and the second region of the display device to receive digital ink input;
adjusting, via the video processor, a size of the second region to receive digital ink input and a size of the first region of the display device to output the image data; and
adjusting, via the video processor, the second set of visual dimensions of image data output to the first region while maintaining the first set of visual dimensions of image data output to the I/O port.

12. The method of claim 11 , wherein:
the second region of the display device to encompass an entirety of a visual output of a panel of the display device and a visual output corresponding to the first region, and
digital ink input received in the second region is mapped, by the video processor, across visual dimensions that include the first set of visual dimensions and the second set of visual dimensions.

13. The method of claim 11 , further comprising:
determining, via the video processor, that an inking-capable display is coupled to the display device; and
virtualizing, via the video processor, a displayable region across the display device and the inking-capable display, such that a boundary between the first region and the second region is adjustable across the display device and the inking-capable display.

14. The method of claim 11 , further comprising:
digitally anchoring, via the video processor, a toolbar to a display location corresponding to a boundary between the first region and the second region,
wherein the toolbar moves corresponding with changes to the boundary and the region of the toolbar is operable in a touch-only mode, a pen-only mode, or a touch-and-pen mode; and
wherein the toolbar includes a feature to enable a user-adjustable pattern to present on the second region of the display.

15. The method of claim 11 , further comprising:
performing, via the video processor, an edge detection operation on the image data;
generating, via the video processor, a trace image using an edge detected via the performing the edge detection operation;
selecting, via the video processor, an adjustment to a navigation pattern, the trace image, or both, in response to user input;
causing, via the video processor, a transparency slider to display on the second region of the display device designated for receiving digital ink input; and
causing, via the video processor, a percentage of opacity of the trace image to adjust according to input received at a location of the transparency slider while the navigation pattern maintains an opacity different from the trace image.
