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.
Claims20
An organic light emitting diode (OLED) display, comprising:
- an OLED panel configured to provide an image;
- and
- an electroconductive (EC) filter configured to permit the image to be viewed within a first viewing angle in response to a first voltage applied to the EC filter, and to permit the image to be viewed exclusively within a second viewing angle in response to a second voltage applied to the EC filter, the first voltage being different from the first voltage, and the first viewing angle being greater than the second viewing angle.
A method for providing a dynamic privacy screen on an organic light emitting diode (OLED) display, the method comprising:
- displaying, on an OLED panel of the OLED display, an image;
- permitting, by an electroconductive (EC) filter of the OLED display, the image to be viewed within a first viewing angle in response to a first voltage applied to the EC filter;
- and
- permitting, by the EC filter, the image to be viewed exclusively within a second viewing angle in response to a second voltage applied to the EC filter, the first voltage being different from the first voltage, and the first viewing angle being greater than the second viewing angle.
An Organic Light Emitting Diode (OLED) display, comprising:
- a transparent OLED panel configured to provide an image in a first direction and in a second direction, the first direction being opposite to the second direction;
- a first electroconductive (EC) filter configured to permit the image to be viewed in the first direction within a first viewing angle in response to a first voltage applied to the first EC filter, and to permit the image to be viewed in the first direction exclusively within a second viewing angle in response to a second voltage applied to the first EC filter, the first voltage being different from the first voltage, and the first viewing angle being greater than the second viewing angle;
- and
- a second electroconductive (EC) filter configured to permit the image to be viewed in the second direction within a third viewing angle in response to a third voltage applied to the second EC filter, and to permit the image to be viewed in the second direction exclusively within a fourth viewing angle in response to a fourth voltage applied to the second EC filter, the third voltage being different from the fourth voltage, and the third viewing angle being greater than the fourth viewing angle.
