Electronic devices with display support structures

An electronic device, comprising:

• a housing having a housing sidewall with an upper surface;
• a display layer comprising pixels and having a flat portion and a curved portion that bends behind the flat portion, wherein the pixels extend to an edge of the flat portion;
• a transparent cover layer overlapping the display layer and having a lower surface;
• an encapsulant material that is injection molded onto the curved portion and the edge of the flat portion of the display layer and that adheres to the transparent cover layer to couple the transparent cover layer to the housing sidewall, wherein the encapsulant material and the curved portion of the display layer are sandwiched between the upper surface of the housing sidewall and the lower surface of the transparent cover layer;
• and
• an adhesive that attaches the encapsulant material to the housing sidewall.

An electronic device, comprising:

• a display cover layer having a lower surface;
• a housing having a housing ledge with an upper surface that supports the display cover layer and that is parallel to the lower surface of the display cover layer;
• a display layer comprising an edge portion and a pixel array that extends onto the edge portion, wherein the display layer displays images through the display cover layer and overlaps the housing ledge;
• and
• first and second materials that adhere to the cover layer to couple the cover layer to the upper surface of the housing ledge, wherein the first and second materials and an edge of the display layer are sandwiched between the lower surface of the display cover layer and the upper surface of the housing ledge, wherein the first material is injection molded onto the edge portion of the display layer, and wherein the first material has a first elastic modulus and the second material has a second elastic modulus that is higher than the first elastic modulus.
