Description
[ technical field ] A method for producing a semiconductor device
The present disclosure relates to display technologies, and in particular, to an organic light emitting display device and a method for manufacturing the same.
[ background of the invention ]
Among organic light-emitting diode (OLED) technologies, a mask technology for vacuum evaporation is an important technology. A mask (or called a photomask) for OLED evaporation usually uses a precision metal mask (FMM), which is used for evaporating a light-emitting layer material.
Currently commercialized OLED panels are large in size, and usually achieve full color by matching a light emitting layer structure and a Color Filter (CF). And the small-size OLED light-emitting panel adopts a precise metal mask plate technology to carry out evaporation of red, green and blue light-emitting materials. The traditional precise metal mask plate has a thin plate (10-100 microns), a minimum opening size of about 20 microns, and a positioning precision of about 3 microns. That is, the FMM has high requirements for processing accuracy, and is likely to fail during processing, resulting in defective products. In addition, as the size of the FMM increases, the middle portion of the FMM is also easily deformed, which causes misalignment of the evaporation material, and eventually causes misalignment and color mixing of the electroluminescent layer and failure in covering the metal via hole. It is therefore clear that FMM is difficult to achieve a large area of deposition, and that its low weight, low thermal expansion coefficient, etc. all affect its processing accuracy. Furthermore, the FMM needs to be cleaned periodically after being evaporated for several times, otherwise the FMM is easy to block, which affects the evaporation quality and increases the manufacturing cost virtually.
