Abstract: A method of fabricating an active matrix organic light emitting diode display is described. A substrate having a light-emitting region and a non-light-emitting region thereon is provided, and pixel structures have been formed in the light-emitting region. A driving IC is formed on the substrate in the non-emitting region and electrically coupled with the pixel structures. A packaging cap is disposed over the substrate and adhered to the substrate. The packaging cap covers the emitting region of the substrate and the driving IC remains being exposed. Since the driving IC is exposed from the packaging cap, the driving IC can be tested or repaired directly when the driving IC is abnormal.

Abstract: A method of fabricating an active matrix organic light emitting diode display is described. A substrate having an emitting region and a non-emitting region thereon is provided. Pixel structures are formed on the substrate in the emitting region, and a power line electrically connected with the pixel structures is formed on the substrate in the non-emitting region at the same time. Then, a cap is deposited above the substrate and bonded with the substrate. The cap covers the emitting region of the substrate and the power line. Since the power line is designed inside the cap, the cap can protect the power line from damage of the outside environment thus improving the lifetime of the display.

Abstract: An organic light emitting display has a plurality of pixels and an external power line. The external power line diverts into a number of internal power lines connected to the pixels, and the internal power lines are segmented into at least two discontinuous parts. Electric current thereby flows in a smaller amount through the internal power lines to reduce power dissipation.

Abstract: A driving circuit design for a display device. This invention uses the voltage-driven circuit of a conventional TFT-LCD such that the pixel is capable of outputting a different driving current to each OLED having a characteristic red, green or blue coloration under identical data voltage conditions. Different driving currents are produced by adjusting channel width/length ratio of the TFT driver in each pixel. Consequently, an appropriate luminance ratio between red, green and blue lights may be set to reproduce white light through the red, green and blue OLED and hence attain full coloration.
