OLED，即有机发光二极管（Organic Light-Emitting Diode），又称为有机电激光显示（Organic Electroluminesence Display， OELD）。OLED由于同时具备自发光，不需背光源、对比度高、厚度薄、视角广、反应速度快、可用于挠曲性面板、使用温度范围广、构造及制程较简单等优异之特性，被认为是下一代的平面显示器新兴应用技术。OLED显示技术具有自发光的特性，采用非常薄的有机材料涂层和玻璃基板，当有电流通过时，这些有机材料就会发光，而且OLED显示屏幕可视角度大，并且能够节省电能，从2003年开始这种显示设备在MP3播放器上得到了应用。LCD都需要背光，而OLED不需要，因为它是自发光的。这样同样的显示，OLED效果要来得好一些。
关于OLED 屏幕的一些资料以及注意事项
1）模块有单色和双色两种可选，单色为纯蓝色，而双色则为黄蓝双色。单色模块每个像素点只有亮与不亮两种情况，没有颜色区分。
2）尺寸小，显示尺寸为0.96寸，而模块的尺寸仅为27mm 26mm大小。
3）高分辨率，该模块的分辨率为12864。
4）多种接口方式，该模块提供了总共4种接口包括：6800、8080两种并行接口方式、 4线的穿行SPI接口方式，、IIC接口方式（只需要2根线就可以控制OLED了！）。
5）不需要高压，直接接3.3V就可以工作了。
这里要提醒大家的是，该模块不和5.0V接口兼容，所以请大家在使用的时候一定要小心，别直接接到5V的系统上去，否则可能烧坏模块。
取字模
使用PCtoLCD2002软件提取OLED字模。

此为模拟IIC，可在myiic.h文件下的宏定义修改IO口。
