| 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。

| Abstract: | 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... |
