The present invention discloses an active organic light emitting diode (AOLED) display structure. A color filter and thin film transistor organic light emitting diode (TFT-OLED) are incorporated on one substrate of the AOLED. Moreover, a Indium Tin Oxide(ITO)layer of the AOLED is deposited with a black matrix layer so as to lower light leakage effect and increase the contrast and color purity level in between pixels of the display. By adopting such technology, a flat panel display having large area, high resolution and low product cost is accordingly implemented.

The present invention relates to a method for transferring devices. A sacrificing layer is positioned before the devices are manufactured, and a transition substrate is pasted on the devices. Then, a method for lateral wet etching or a method for lateral wet etching with mechanical stripping is applied for removing or stripping the sacrificing layer so as to separate the devices and a substrate. The separated devices are transferred to the transition substrate so as to meet the requirements for various products and applications.

A method for forming a conductive layer is disclosed, which has the following steps. First, a substrate is provided, and then a patterned photoresist layer having an undercut is formed on the substrate. After that, at least one conductive layer is deposited on the substrate. Finally, the patterned photoresist layer is lifted off; wherein the shape of the conductive layer remaining on the substrate is complementary to that of the patterned photoresist layer.
