Stretchable display with fixed pixel density

A variable area display comprising:

• a first display layer including first display elements;
• and
• a second display layer in juxtaposition with the first display layer, the second display layer including:
• an expandable substrate;
• and
• second display elements coupled to the expandable substrate, the second display elements arranged in a matrix and spaced apart from each other, the second display layer expandable between a first display position in which the second display elements obscure a first portion of the first display elements and a second display position in which the second display elements obscure a second portion of the first display elements, the second portion being less than the first portion.

A non-transitory storage device comprising instructions that, when executed, cause at least one processor to at least:

• determine an exposed portion of a set of lower display elements of a variable area display, the variable area display including a lower display layer and an upper display layer spaced above the lower display layer, the lower display layer including the set of lower display elements, the upper display layer including an expandable substrate and a set of upper display elements coupled to the expandable substrate;
• determine a first portion of a display image to be displayed using the set of upper display elements;
• and
• determine a second portion of the display image to be displayed using the exposed portion of the set of lower display elements.

An electronic device comprising:

• memory;
• instructions;
• a processor to execute the instructions;
• a lower display layer, the lower display layer including lower display elements;
• and
• an upper display layer spaced relative to the lower display layer, the upper display layer including upper display elements, the upper display elements moveable away from each other between (1) a first position in which the upper display elements obscure a portion of the lower display elements and (2) a second position in which the upper display elements expose the portion of the lower display elements.
