摘要

基于发光二极管 (Light-emitting Diode

LED)的电脉冲响应过程

建立了一个简便计算LED电脉冲响应模型。在此模型基础上研究了采用脉宽调制(Pulse-width Modulation

PWM)控制LED亮度时

由于LED响应延迟所导致的发光强度随占空比的非线性误差的变化情况

并进行了实验测试。结果表明:在PWM频率为2.5 MHz时

LED发光强度与占空比的平均非线性误差为10%左右。最后

针对LED电脉冲响应模型

提出了显示屏像素亮度校正方法。该方法有效减小了由LED响应过程所造成的显示屏亮度控制误差

使得LED实际发光强度与所给亮度值近似成线性关系

从而减小了LED显示屏的色彩偏离

增强了显示效果。
