Abstract

Provided is a modular display device for providing a digital representation of a blueprint. In one example, the device includes an elongated housing having an elongated opening parallel to a longitudinal axis of the housing. A core is configured to fit inside the housing in a rotatable manner. A flexible display is configured to move between one state where a majority of the flexible display is positioned inside the housing and rolled around the core and another state where a majority of the flexible display is moved out of the housing through the opening and positioned outside of the housing to form a viewing surface. A height and a width of the flexible display are sufficient to provide a 1:1 scale view of a drawing having dimensions defined by a drawing standard used in at least one of an architectural industry, an engineering industry, or a construction industry.

Claims

1. A modular display device for providing a digital representation of a blueprint comprising:

an elongated housing having a closed first end, a closed second end, and an elongated opening extending at least partially between the first and second ends, wherein the opening is parallel to a longitudinal axis of the housing;

a substantially cylindrical core configured to fit inside the housing in a rotatable manner;

a flexible display configured to move between a first state where a majority of the flexible display is positioned inside the housing and rolled around the core and a second state where a majority of the flexible display is moved out of the housing while rotating the core through the opening and positioned outside of the housing to form a viewing surface, the flexible display having a first edge secured to the core, wherein a height and a width of the flexible display are sufficient to provide a 1;

1 scale view of a drawing having dimensions defined by a predetermined drawing standard;

a plurality of electronic components positioned inside the housing and within the core and rotatable with the core, the electronic components operable to generate signals to control and/or power the flexible display and including a processor, a memory coupled to the processor, display circuitry coupled to the processor and the flexible display, and a power supply coupled to the processor, the memory, and the flexible display, wherein the electronic components can be easily replaced by replacement of the core; and

a communication interface to the exterior of the elongated housing to allow communication with an external communication device while the elongated housing is rotating with respect thereto and at all rotatable positions thereof.

2. The modular display device of claim 1 further comprising a wire coupling the processor to one of a control feature and to a communication port on the exterior of the housing through the communications interface.

3. The modular display device of claim 2 wherein the wire is attached via a slip ring connection as the communication interface, wherein rotation of the core relative to the housing does not negatively affect the wire, which also rotates with the core.

4. The modular display device of claim 1 wherein the core includes a channel configured to secure the first edge to the core by receiving in the channel a bar coupled to the first edge.

5. The modular display device of claim 4 wherein the core further includes a sloped surface that forms at least a part of the channel.

6. The modular display device of claim 1 further comprising at least one control feature positioned on an exterior side of the housing, wherein the at least one control feature is coupled to the processor.

7. The modular display device of claim 1 wherein a second edge of the flexible display is coupled to a stop bar that is positioned outside of the housing, wherein the stop bar is too large to pass through the opening in the housing.

8. The modular display device of claim 7 further comprising at least one control feature positioned on the stop bar, wherein the at least one control feature is coupled to the processor.

9. The modular display device of claim 1 wherein the flexible display is an electronic ink display.

10. The modular display device of claim 1 further comprising a tension mechanism configured to place tension on the core to rotate the core in a direction that places the flexible display in the first state.

11. The modular display device of claim 10 further comprising a locking mechanism configured to offset the tension produced by the tension mechanism and lock the flexible display in the second state.

12. The modular display device of claim 1 further comprising a removable end cap configured to couple to the first end, wherein decoupling the removable end cap from the first end enables the core to be removed from the housing.

13. The modular display device of claim 1 wherein a longitudinal axis of the core lies along the longitudinal axis of the housing.

14. The modular display device of claim 1 wherein a longitudinal axis of the core is parallel to the longitudinal axis of the housing but offset from the longitudinal axis of the housing.

15. The modular display of claim 1, wherein the communication interface is a USB interface and the external communication device is a USB interface.

16. A modular display device for providing a digital representation of a blueprint comprising:

an elongated housing having an elongated opening parallel to a longitudinal axis of the housing;

a core configured to fit inside the housing in a rotatable manner, wherein a longitudinal axis of the core is parallel to the longitudinal axis of the housing;

a flexible display configured to move between a first state where a majority of the flexible display is positioned inside the housing and rolled around the core and a second state where a majority of the flexible display is moved out of the housing through the opening during rotation of the core and positioned outside of the housing to form a viewing surface, wherein a height and a width of the flexible display are sufficient to provide a 1;

1 scale view of a drawing having dimensions defined by a predefined drawing standard;

a plurality of electronic components positioned inside the housing and within the core and rotatable with the core, wherein the electronic components are operable to generate signals to control and/or power the flexible display and can be easily replaced by replacement of the core and wherein the plurality of electronic components comprise a processor, a memory coupled to the processor, display circuitry coupled to the processor and the flexible display, and a power supply coupled to the processor, the memory, and the flexible display; and

a communications interface to the exterior of the elongated housing to allow communication with an exterior communication device while the elongated housing is rotating with respect thereto and at all rotational positions of the core.

17. The modular display device of claim 16 wherein the power supply is configured to power the flexible display and circuitry for receiving data from an external device via the communications device for display on the flexible display.

18. The modular display device of claim 16 wherein the height of the flexible display is at least thirty inches and the width is at least forty-two inches.
