OLED即有机发光管(Organic Light-Emitting Diode，OLED)。OLED显示技术具有自发光、广视角、几乎无穷高的对比度、较低功耗、极高反应速度、可用于绕曲性面板、使用温度范围广、构造及制程简单等有点，被认为是下一代的平面显示屏新兴应用技术。
OLED显示和传统的LCD显示不同，其可以自发光，所以不需要背光灯，这使得OLED显示屏相对于LCD显示屏尺寸更薄，同时显示效果更优。
常用的OLED屏幕有蓝色、黄色、白色等几种。屏的大小为0.96寸，像素点为128*64，所以我们称为0.96oled屏或者12864屏。
OLED屏幕特点
模块尺寸：23.7 *23.8mm电源电压：3.3-5.5V驱动芯片：SSD1306测试平台：提供 k60/k10，9s12XS128，51，stm32，stm8等单片机。OLED屏幕接线说明
OLED屏幕显存
OLED本身是没有显存的，他的现存是依赖SSD1306提供的，而SSD1306提供一块显存。
SSD1306显存总共为128*64bit大小，SSD1306将这些显存分成了8页。每页包含了128个字节。
0.96寸的oled又叫12864显示屏，分辨率为128*64（这么多个像素点），由128列，64行组成，其中64行又被分为8页，每页8行！
OLED屏幕原理
STM32内部建立一个缓存(共128*8个字节），每次修改的时候，只是修改STM32上的缓存(实际上就是SRAM)，修改完后一次性把STM32上的缓存数据写入到OLED的GRAM。
这个方法也有坏处，对于SRAM很小的单片机（51系列）就比较麻烦。
OLED屏幕常用指令
命令0X81：设置对比度。包含两个字节，第一个0X81为命令，随后方法是的一个字节要设置这个对比度，值越大屏幕越亮。
命令0XAE/0XAF：0XAE为关闭显示命令，0XAF为开启显示命令
命令0X8D：包含两个字节，第一个为命令字，第二个为设置值，第二个字节的BIT2表示电荷泵的开关状态，A2该位为1（0x14）开启电荷泵，为0（0x10）则关闭。模块初始化的时候，这个必须要开启，否则看不到屏幕显示。
命令0XB0~B7：用于设置页地址，其低三位的值对应GRAM页地址。
命令0X00~0X0F：用于设置显示时的起始列地址低四位。
命令0X10~0X1F：用于设置显示时的起始列地址高四位。
OLED屏幕字模软件的使用
OLED点阵的点亮方式，举个显示”P”的例子，最左边位最高位P7。
这个图画错了从下到上应该是8个点，他画了9个点。从下至上第2个点开始。
可以看出，要想显示”P”，首先写入0x1f，则显示一个竖杠，之后控制器自动水平移动到下一列。
再写入0X05,则出现两个小横杆，这个两个横杆就是0X05中0000 0101中两个1所处的位置，写完第二列后，控制器自动跳到第三列.
再写入0X07,第四列写入0X00后，P就显示出来了。这也说明，即使你只想再一列的最上端显示一个小点，即写入0X01。
即你不能一次性控制一个点阵，只能一次性控制八位点阵，即一列点阵。这也决定了字模选择的取模方式为“列行式”。
写命令
void WriteCmd(unsigned char I2C_Command){I2C_WriteByte(0x00,I2C_Command);//从0x00开始写指令}
写数据
void WriteData(unsigned char I2C_Data){I2C_WriteByte(0x40,I2C_Data);//从0x40开始写数据}

void OLED_setPos(unsigned char x,unsigned char y){WriteCmd(0xb0+y);//设置页 0xB0代表页为第0页WriteCmd( (x&0xf0) >>4 | 0x10); //设置列 高四位 获取高四位数据右移动4位并保存，且让第5位为1WriteCmd( (x&0x0f) | 0x01);//设置列 低四位 保留最后一位数据，并让最后一位数据置1}
