1. A composite structure configured to support a flexible display and comprising:
a first titanium alloy layer comprising:
a first surface proximate to the flexible display; and
a second surface opposite to the first surface; and
a second layer stacked with the first layer and configured to dissipate heat, wherein the second layer comprises:
a third surface proximate to the second surface; and
a fourth surface opposite to the third surface;
wherein the first layer is configured to couple the second layer with the flexible display,
wherein a first elastic modulus of the first layer is greater than or equal to a second elastic modulus of the second layer, and
wherein a first coefficient of thermal conductivity of the first layer is less than or equal to a second coefficient of thermal conductivity of the second layer.
