有机发光二极管最简单的形式是由一个发光材料层组成，嵌在两个电极之间。输入电压时载流子运动，穿过有机层，直至电子空穴并重新结合，这样达到能量守恒并将过量的能量以光脉冲形式释放。这时其中一个电极是透明的，可以看到发出的光。oled显示屏显示原理图

When the pin is low, initialization of the chip is executed. Keep this pin pull high during normal operation. 13 CS# I C Ch hi ip p S Se el le ec ct t This pin is the chip select input. The chip is enabled for MCU communication only when CS# is pulled low. 15 D/C# I Da at ta a/ /C Co o m ma an nd d C Co on nt tr ro ol l This pin is Data/Command control pin. When the pin is pulled high, the input at D7~D0 is treated as display data. When the pin is pulled low, the input at D7~D0 will be transferred to the command register. When the pin is pulled high and serial interface mode is selected, the data at SDIN will be interpreted as data. When it is pulled low, the data at SDIN will be transferred to the command register. In I 2 C mode, this pin acts as SA0 for slave address selection. For detail relationship to MCU interface signals, please refer to the Timing Characteristics Diagrams. 17 E/RD# I R Re ea ad d/ / Wr ri it te e E En na ab bl le e o or r R Re ea ad d This pin is MCU interface input. When interfacing to a 68XX-series microprocessor, this pin will be used as the Enable (E) signal. Read/write operation is initiated when this pin is pulled high and the CS# is pulled low. When connecting to an 80XX-microprocessor, this pin receives the Read (RD#) signal. Data read operation is initiated when this pin is pulled low and CS# is pulled low. When serial or I 2 C mode is selected, this pin must be connected to V SS .

When interfacing to a 68XX-series microprocessor, this pin will be used as Read/Write (R/W#) selection input. Pull this pin to “High” for read mode and pull it to “Low” for write mode. When 80XX interface mode is selected, this pin will be the Write (WR#) input. Data write operation is initiated when this pin is pulled low and the CS# is pulled low. When serial or I 2 C mode is selected, this pin must be connected to V SS . 18~25 D0~D7 I/O Ho os st t Da at ta a I In np pu ut t/ / Ou ut tp pu ut t B Bu us s These pins are 8-bit bi-directional data bus to be connected to the microprocessor’s data bus. When serial mode is selected, D1 will be the serial data input SDIN and D0 will be the serial clock input SCLK. When I 2 C mode is selected, D2 & D1 should be tired together and serve as SDA out & SDA in in application and D0 is the serial clock input SCL. Unused pins must be connected to V SS except for D2 in serial mode.
