    Abstract: The invention provides a flexible display substrate and manufacturing method thereof. The manufacturing method for flexible display substrate patternizes the inorganic layer between the two organic layers on the flexible substrate so that the two organic layer contacting each other at the gaps on the inorganic separation layer, so as to avoid the potential damage on the films during the subsequent laser-lift-off process. The method is simple and the manufacturing process is efficient. The flexible display substrate of the present invention uses a structure of stacked four thin film layers to realize effective water/oxygen blocking, thus avoiding display devices' eroding. The inner two organic layers of the flexible substrate contact each other directly at the gaps of the inorganic separation layer, and the high adhesion strength between the upper and lower film layers of the flexible substrate helps avoiding film-peeling inner the stacked structure.

    Abstract: The present invention provides a vertical channel organic thin-film transistor and a manufacturing method thereof. The vertical channel organic thin-film transistor includes: an annular organic semiconductor layer, an annular drain electrode and an annular source electrode respectively set in contact with upper and lower sides of the annular organic semiconductor layer, and a gate electrode arranged inwardly of an inner circle of the annular organic semiconductor layer and insulated and isolated from the annular organic semiconductor layer. An effective conductive channel length of the thin-film transistor can be varied by changing a thickness of the organic semiconductor layer made with a solution method so that the definition of a short channel pattern no longer relies upon high precision exposure and etching equipment and thus, the difficulty and the cost of the manufacturing process can be reduced. Further, the annular electrode structure makes it possible to save a planar space of the thin-film transistor, increasing scenarios of application of the thin-film transistor, and improving flexibility of circuit design.

    Abstract: A manufacturing method of an organic thin film transistor includes: forming source and drain electrodes on a substrate; irradiating a photosensitive outer surface with a first charge of a photosensitive roller by laser to pattern the photosensitive outer surface and forming a channel pattern area without charge; spraying an atomized organic material solution with a third charge having same polarity as the first charge onto the channel pattern area to make the organic material solution be absorbed onto the channel pattern area and thereby form a channel region layer; attaching a fourth charge having an opposite polarity to the third charge onto a surface of the substrate disposed with the source and drain electrodes; and transferring a channel pattern in the channel region layer onto the substrate and connected with the source and drain electrodes and thereby forming a channel region. A manufacturing apparatus also is provided.
