Description
Technical Field

Background

OLEDs can be classified into two broad categories, namely, direct addressing and thin film transistor Matrix addressing, namely, Passive Matrix OLEDs (PMOLEDs) and Active Matrix OLEDs (AMOLEDs) according to driving methods. The AMOLED has pixels arranged in an array, belongs to an active display type, has high luminous efficiency, and is generally used as a large-sized display device with high definition.
OLED devices typically include: the electron injection device comprises a substrate, an anode arranged on the substrate, a hole injection layer arranged on the anode, a hole transport layer arranged on the hole injection layer, a luminescent layer arranged on the hole transport layer, an electron transport layer arranged on the luminescent layer, an electron injection layer arranged on the electron transport layer and a cathode arranged on the electron injection layer. The light emitting principle of the OLED device is that a semiconductor material and an organic light emitting material emit light under the drive of an electric field through carrier injection and recombination. Specifically, an Indium Tin Oxide (ITO) electrode and a metal electrode are generally used as an anode and a cathode of the device, respectively, and under a certain voltage, electrons and holes are injected into an electron transport layer and a hole transport layer from the cathode and the anode, respectively, and the electrons and the holes migrate to a light emitting layer through the electron transport layer and the hole transport layer, respectively, and meet in the light emitting layer to form excitons and excite light emitting molecules, which emit visible light through radiative relaxation.
However, the yield of OLED products is low and the cost is high due to the immature technology, and the correlation between the process conditions and the yield of OLEDs in the production process is large, however, the process conditions affect the yield of OLEDs and the yield is also affected by the equipment mechanism. The flexible OLED product is easy to cause defects such as scratches, scratches or cracks (Crack) in the process of contacting with other equipment mechanisms. After being scratched, the upper and lower protective layers of the OLED product are easy to crack, and the light emitting layer of the OLED product is easy to be oxidized and burnt. Such defects not only affect the appearance of the product and reduce the user experience, but also reduce the service life. In addition, normal lighting is difficult to find after the defects are generated, the defects can be seen only under strong light reflection, and manual observation and judgment are needed, so that the product yield is greatly reduced due to the production abnormity, and the production cost is improved.
In addition, the OLED product itself is limited in the number of reads and writes of the product register chip and the number of crimps of the flexible circuit board connector by some special reasons (for example, the number of reads and writes of a flash memory (flash) is limited, and the flexible circuit board connector is easily damaged in the crimping process).
