The Software Design And Implementation Of The OLED Multifunction Telephone

OLEDs are widely considered to be the leading next-generation flat panel displaytechnology for their superior performance compared with other display devices, such aslow power consumption, high contrast, fast response time, better viewing angles andthey can operate in a broader temperature range, and etc. So they have good prospectsand can be widely used in the future. Nowadays, OLED technology has gradually comeinto commercialization. Although large-size OLED display technology is still immatureand not competitive，small-size OLED technology has already been available in themarket gained the market recognition. This issue applied1.0inch OLED screens intraditional telephone keys and combines the head portrait on the OLED screens dialkeys.Focusing on PMOLED screen applications, CCO suggests the OLED Smart Phonedevelopment plan.The project is fundamentally an innovation on existing telephone morphology. As ahigh-end high-tech fashionable electronic communication product, OLED Smart Phoneintegrates a lot of functions together: fixed dialing number for SOS, answering, and etc.OLED Smart Phone becomes a major highlight of the telephone industry and1.0inchOLED display applications.The main work is the OLED phone display control part of the software design.Main core work is the following three aspects:(1) Alternative to ordinary telephone digital keys with OLED display, buttonimage.(2) The use of UART communication, display control module and communicationmodule communication, to complete the phone call function and dialing function.(3) The use of image processing chip, drive camera module, achieve avatarphotographed and bind with the number corresponding avatar display a key avatardialing and Caller ID.This article introduces the OLED Smart Phone hardware system constitute, criticalcomponent selection and system software design, and focuses on general-purposemicrocontroller, controlling the preview and photograph of the camera module, associating the pictures stored in FLASH, introducing PMOLED display drivingmethod and software modules code design. Finally, the verification of the systemhardware and software design by assemblying and debugging the OLED Smart Phone.
