A flexible display capable of improving an angle-measuring accuracy using different kinds of sensors and a method of measuring an angle thereof. The flexible display includes a first sensor unit disposed in a first region and including different kinds of sensors, a second sensor unit disposed in a second region adjacent to the first region and including different kinds of sensors, and an angle-measuring unit measuring a folding angle between the first region and the second region in response to sensing signals outputted from the first sensor unit and the second sensor unit.

Flexible display and method for measuring angle of the same

A positive active material, a method of preparing the positive active material, a positive electrode including the positive active material, and a lithium battery including the positive active material are disclosed. The positive active material includes a core and a coating layer on the core. The coating layer includes a sulfur component. When a binding energy peak of the sulfur is measured by X-ray photoelectron spectroscopy (XPS), the binding energy peak is observed at about 165 eV to about 168 eV, and the stability of the positive active material may be improved due to the coating layer. Accordingly, the lifespan properties of a lithium battery including the positive active material may be improved.

Positive active material, positive electrode, and lithium battery including the same and method of manufacture thereof
