Design And Implementation Of A Kind Of Multifunctional Small Size Pmoled Display System

OLED(Organic Light Emitting Diode), as the promising display technology of the future, can fully meet and implement the needs of the innovation in display from its principle. Nowadays, the trend of the skill in OLED is still in the state of a small size screen phase. Therefore, the research and application of OLED in small size has been the priority task at the current situation.This topic is part of the electronic design which mainly uses the microelectronics, the field of the circuit, the software language, the software programming, the structure intellectual of mould, the knowledge of the display skill about OLED, the science of the drive technology related to OLED. The key point of the thesis is to produce a showing board in a size of 12 screen with a PMOLED screen in a inch of 1.5 and 1. As a result, it is not only making a depth research and practice for the small size of PMOLED screen, but also lay a foundation for the application of the small size of OLED.developmentThe chief research of the thesis includes:First of all, the thesis presents the related skills, covering the technology of OLED and single-chip microcomputer. Second, the design of the system and the systematic circuit, the key skill and difficult, and the research of the environment have been made into an overall design. Then, the research of the software design has got a further success, which includes the flow diagram of software system, the function modules of software, the initialization of system, the display driver of OLED, 3 * 4 OLED display module, button scanning module, the speaking and reading of the FLASH module and the standby module.Finally, the main system test work has been completed, incorporating the test of software, circuit and black screen. The system prototype and function can fully play roles successfully in the related tests.
