摘要
将液晶屏的对比度调节决定其是否能够有效显示的这个关键因素,化为以显示效果为目标函数的参数寻优问题。因此用遗传算法求取液晶屏对比度较优值,减少寻优时间,提高收敛性。进行了可以输入选择值的触摸屏和显示对比度效果值的液晶屏的硬件系统设置。在遗传算法设计中重点说明了目标函数、适配值和复制概率的特点。完成了单片机C51编程和实现。实际运行确认了方法的正确性和实用性。
The adjustment of the contrast degree is the key factor for the LCD display. An optimization problem for the adjustment is formed. The optimal value of the contrast degree of LCD is solved by the Genetic Algorithm. The features of the target function, the adjustable value, and the reproduction probability are discussed. The hardware configuration is outlined. And the programming in MCU is realized by C51.
