Abstract

An organic electroluminescent display device (10) includes a first display region (12) and a second display region (14), each region adapted to provide a different type of information. For example, first display region (12) may be adapted to display icon information, while second display region (14) may be adapted to provide dynamic or changing information such as video or alpha numeric information. The display device (10) may include an organic electroluminescent display module (62) having a plurality of picture elements, said picture elements optionally having corresponding light influencing elements (58 and 102-110) for providing full color icon or dynamic information.

Claims

1. An organic electroluminescent information display device comprising:

a display substrate having a surface;

a spacer material disposed on the surface of the display substrate;

a transparent conductive material disposed on the spacer material;

an organic electroluminescent material disposed on the transparent conductive material;

a plurality of display electrodes disposed on a first portion of the organic electroluminescent material for, in conjunction with the transparent conductive material and the organic electroluminescent material, forming a plurality of pixels of a dynamic display; and

an icon electrode disposed on a second portion of the organic electroluminescent material for, in conjunction with the transparent conductive material and the organic electroluminescent material, forming a static display.

2. The organic electroluminescent information display device of claim 1 further comprising an influencing element disposed between the display substrate and the spacer material and in alignment with the icon electrode for influencing the color of the static display.

3. The organic electroluminescent information display device of claim 1 further comprising a plurality of influencing elements disposed between the display substrate and the spacer material, each one of the plurality of influencing elements in alignment with each one of the plurality of display electrodes for influencing the color of the dynamic display.
