液晶显示器（Liquid Crystal Display，简称LCD），为平面超薄的显示设备，它由一定数量的彩色或黑白像素组成，放置于光源或者反射面前方。液晶显示器功耗很低，并且具有高画质、体积小、重量轻的特点。液晶显示面板是液晶显示器的主要组件，其一般包括相对设置的彩膜基板和薄膜晶体管（Thin Film Transistor，简称TFT）阵列基板以及夹在两基板之间的液晶层。随着平板显示技术的发展，人们对画面的品质要求越来越高，其中包括：亮度、色彩度、分辨率、视角、刷新速度等。
 技术问题
由于整机组装差异，会导致不同液晶显示面板存在颜色差异；或由于数据信号的延迟，会导致液晶显示面板在显示一些画面时候存在色偏问题。因此，会通过光学的白平衡（White Tracking，简称WT）调整来进行白平衡校正。白平衡校正时通过调整相关白平衡参数以进行补偿，使得不同整机的液晶显示面板达到同一色坐标误差范围之内，减轻色偏现象。
但随着液晶显示面板的运行，其液晶层中的液晶相应会发生老化，使得液晶的光学特性发生改变。而预先调整后的白平衡参数却一直是同一组参数，并不会更新；若仍旧按照原始的白平衡参数进行补偿，则会影响白平衡校正结果，无法提升液晶显示品质。

具体地，可以采用第二存储器存储所述总运行时间与白平衡参数表。所述第二存储器在信息写入后，即使切断电源，信息也不会丢失。所述第二存储器可以采用可编程只读存储器、可擦除可编程只读存储器、电可擦除可编程只读存储器、快闪存储器等。本次开机上电所采用的白平衡参数，为根据从所述第一存储器中读取的总运行时间（即本次开机前所述液晶显示面板已运行的时间），在所述总运行时间与白平衡参数表中匹配出的相应白平衡参数。本次开机上电后可以计时本次的运行时间，并叠加先前从所述第一存储器中读取的运行时间，形成总运行时间，以更新所述第一存储器中的总运行时间。从而在下一次开机上电后所采用的白平衡参数，为根据从所述第一存储器中读取的更新后总运行时间所匹配出的相应白平衡参数。从而可以随所述液晶显示面板的运行时间（运行时间反映液晶显示面板中液晶的老化情况）调整所述白平衡参数。
由于所述白平衡参数是与所述液晶显示面板的运行时间相关的；即，根据所述液晶显示面板的运行时间，而选择使用不同的白平衡参数进行补偿，而非相应固定一组白平衡参数的补偿方式；从而可以改善白平衡校正结果，提升液晶显示品质。
