摘　　要：在液晶显示器生产过程中,白平衡的调整是一个关键部分,目前大都采用PC机调整。针对现有调整方法的不足,提出了一种白平衡调整方案。该方案包括了两个步骤,首先,利用LCD显示器自身的嵌入式平台实现输入信号和前端采样A/D的误差校正;然后,采用PC机与彩色分析仪Chroma7120,通过曲线拟合的方法补偿后端显示屏的色温差异,实现LCD白平衡的自动调整。实验结果表明该方案既方便又能满足白平衡的调整要求。Adjusting of liquid crystal display（LCD） white balance is a key factor during the LCD production process.At present,LCD white balance is adjusted by PC on product line.This paper proposes a new method that automatic adjusting of LCD white balance will be implemented.Firstly,error of input signal and A/D is corrected based on embedded system of LCD.Secondly,difference of color temperature between different panels is compensated based on PC and Chroma7120.The result of experiment indicates the method can meet the requirement and operate conveniently.
