Electronic retractable blueprint display device for viewing and manipulating full-size and half-size architectural, engineering, and construction plans

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.
