The Fabrication Of Passive Matrix Display Of OLED

Organic Electro-luminescent devices (OLED) is regarded as the third generation display technology, because OLED has the advantages of higher performance than those of other display technologies. And the OELD is becoming more and more the focal point of display domain. The luminescence, mechanism, the operation mechanism and the devices structure, as well as organic materials are all summarized in this paper. The developing status and prospect of the OLED are also introduced. We have contrasted several methods on fabrication of passive matrix OLED, then we mainly discuss two fabricating methods, one is the precise mask method, the other is the barrier wall method. We find that the barrier wall method to fabricate the passive matrix OLED (PMOLED) has the advantages of high resolution, simple process and no crosstalking problem, so the barrier wall method is the good one to fabricate PMOLED. In this paper we adopt the both methods, and we have successfully fabricated the PMOLED. In this paper, we design and fabricate several kinds of PMOLED, and we explore and optimize the fabricating process. At the same time, we investigate the performance of the PMOLED. We propose the ideas to improve the performance of the PMOLED. We also investigate the principle of invalidation and give the ways to solve such problems.In the end of this paper, we conclude the methods and successful or failed experience of fabrication PMOLED. It is very useful to fabricate the PMOLED in the future.
