Abstract
An organic light emitting diode (OLED) display includes an OLED panel and an electroconductive (EC) filter. The OLED panel provides an image. The EC filter permits the image to be viewed within a first viewing angle in response to a first voltage applied to the EC filter, and permits the image to be viewed exclusively within a second viewing angle in response to a second voltage applied to the EC filter.
