Organic light emitting diode display
View Patent ↗An organic light emitting diode display includes a panel assembly for displaying an image and a first surface stress enhancing member arranged on a rear surface of the panel assembly. In one embodiment, the organic light emitting diode display includes a second surface stress enhancing member arranged on a front surface of the panel assembly. In anther embodiment, the organic light emitting diode display includes a lower bezel arranged on a rear surface of the first surface stress enhancing member and a shock absorption tape arranged between the first surface stress enhancing member and the lower bezel. The structure of the organic light emitting diode display efficiently prevents damages caused by an external impact.
