Miniature Oled Screen Display Control Technology Research

In consumer electronics products more and more feature-rich conditions,Monitor as human-computer interaction interface has become increasingly important.With the rapid development of science and technology,the increase in density of circuit,customer has higher and higher requirement on the product of multifunctional,low power and protability.In this conditions,micro OLED with its exceptional unique display performance,becomes the ideal monitor in the portable multimedia equipment,on-board equipment display and other areas. This paper designs a common module of micro OLED display.The module can easily integrated into a portable device which complies with the device development trend for miniaturization and multi-functionality and provides the display reference scheme for light thermal weapon.First of all,this paper compares the advantages and disadvantages of the present mainstream display technology,some basic concepts and display driving principle of micro OLED are introduced,and it puts emphasis on features and working function of EMA-100080 micro OLED display that using in the system, the theory basis are provided for driving micro OLED display.Then the system hardware circuit board designed,hardware circuit uses the FPGA IC chip of the Altera CycloneⅢseries as the main video processing chip,and combines with the A/D conversion and data storage to realize the video processing.In addition. The system adds three serial interface that can be connected to the external device which through the serial port to communicate with FPGA.In this way, the system increases more functional and compatibility. Finally in detail introduced the video conversion plan of PAL format to SVGA format.Through the FPGA to simulation I2C Bus,serial to parallel convert,conversion from interlaced scan to progressive scan,resolution conversion and so on to realize the video format conversion.High resolution SVGA display format can bring more excellent display effect.In the meantime the GPS receiver and laser distance-measuring sensor communication with FPGA through a serial port,at the fixed location of the video image display overlay location and distance information.So in the same monitor can have multiple observed around the situation and more accurate control to surrounding environment.In this paper,combining theory and experiment, as far as possible to save the memory resources under the precondition that the system function realization,providing convenient conditions for enhancement of follow-up system function.At last,after system of hardware and software debugging and then realizes the prospective effect in micro OLED display chip.
