Abstract

A full-color organic electroluminescence (OEL) display panel includes a substrate and a plurality of full-color OEL pixel devices in a matrix form as a display frame. Each of the pixel devices is composed of a plurality of sub-pixel regions, corresponding to R, G or B colors. Each of the specific color sub-pixel regions in the pixel device abuts the same specific color sub-pixel region of the adjacent pixel device thereof to form a double-sized area. With this arrangement of sub-pixel regions, it is easier to manufacture high-resolution full-color OLED panels by a metal-mask alignment process and high-resolution full-color PLED panels by an ink-jet printing process.

Claims

1. A full-color organic electroluminescence (OEL) display panel, comprising:

a substrate;

a plurality of pixel devices, formed on said substrate in a matrix form as a display frame and each said pixel device comprising a plurality of sub-pixel regions and each of the sub-pixel region with a specific color in said pixel device abutting the same-color sub-pixel region of the adjacent pixel device thereof and forming a double-sized area.

2. The full-color OEL display panel of claim 1, wherein said substrate is selected from a group consisting of glass, quartz and plastic.

3. The full-color OEL display panel of claim 1, wherein said sub-pixel region includes at least a red sub-pixel region, a green sub-pixel region and a blue sub-pixel region.

4. The full-color OEL display panel of claim 1, wherein said sub-pixel region is driven in active-matrix scheme or passive-matrix scheme.

5. The full-color OEL display panel of claim 1, wherein said sub-pixel region is a top-emission device or a bottom-emission device.

6. The full-color OEL display panel of claim 1, wherein said sub-pixel region is a OLED.

7. The full-color OEL display panel of claim 1, wherein said sub-pixel region is a PLED.

8. The full-color OEL display panel of claim 1, wherein the geometrical shape of said sub-pixel region is selected from a group consisting of rectangular, trapezoid, angular, regular polygon and a geometrical shape having an arc.

9. The full-color OEL display panel of claim 8, wherein said plurality of sub-pixel regions have the same specific geometrical shape in identical said pixel device.

10. The full-color OEL display panel of claim 8, wherein said plurality of sub-pixel regions have different specific geometrical shape in identical said pixel device.
