  • Organic electroluminescent display panel with dummy areas
    Patent number: 7564183
    Abstract: An organic electroluminescent display panel, which comprises a substrate, at least one display structure area, at least one first dummy area, and at least one second dummy area. The display structure area comprises at least one encapsulation area, at least one pixel area, a first conducting area, a second conducting area, a wiring area, a first connecting area, and a second connecting area. The wiring area and the first dummy area connect the first connecting area, and the two conducting areas and the second dummy area connect the second connecting area. Besides, the first and the second connecting areas overlap a selected part of the encapsulation area of a neighboring display structure area. Accordingly, the number and capacity of display structure areas on the organic electroluminescent display panel are increased to obtain a uniform brightness during a lighting test.
