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128
64。
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。
