Abstract
The present invention provides a manufacturing method of a flexible OLED display panel, in which multiple loops of inorganic barrier walls are first formed on a rigid base plate such that the multiple loops of inorganic barrier walls respectively and circumferentially encloses a plurality of panel areas on the rigid base plate so that when an organic material film is then coated on the rigid base plate and the multiple loops of inorganic barrier walls in a manner of covering the entirety of surface thereof, the multiple loops of inorganic barrier walls provide an effect of division to allow a plurality of flexible backings to be respectively formed on the plurality of panel areas of the rigid base plate. Afterwards, a laser lift off technique is applied to remove the plurality of flexible backings from the rigid base plate to thus obtain a plurality of flexible OLED display panels. Compared to the prior art, the present invention saves a process of using a laser cutting machine to simultaneously cut the organic material film and the rigid base plate and thus saves the cost of purchasing the laser cutting machine and also save one round of laser cutting operation to thereby reduce t…
