Abstract
Display structures and methods of assembly are described. In an embodiment, a display structure includes a display panel including a pattern of trenches extending at least partially through a backplane of the display panel, without extending past a matrix of LEDs in an overlying emission layer stack. The plurality of trenches can be formed in 2D to facilitate bending of the display panel into a 3D film curvature.
Claims29
A display structure comprising:
- a display panel including a display area spanning across a main body area and an edge area around the main body area of the display panel;
- wherein the display panel includes:
- a backplane including light emitting diode (LED) driver circuitry;
- an emission layer stack spanning over the backplane, the emission layer stack including a matrix of LEDs dispersed across the display area and electrically connected with the LED driver circuitry;
- and
- a pattern of trenches extending at least partially through the backplane in the edge area of the display panel, where the trenches do not extend past the matrix of LEDs in the emission layer stack.
