Description

数据处理方法、显示装置和计算机可读存储介质
技术领域
本申请涉及显示技术领域，尤其涉及数据处理方法、显示装置和计算机可读存储介质。
背景技术
随着科技水平的不断提高，越来越多带有显示装置的设备进入人们的日常生活和工作当中，例如，电视、手机等。TFT-LCD（Thin Film Transistor-Liquid Crystal Display，薄膜晶体管液晶显示器）之所以能显示不同的颜色与画面，是因为面板内有很多个R（红色）、G（绿色）和B（蓝色）子像素，这3个子像素可以在不同亮度下显示出不同的颜色。由于蓝色光的波长短，因此B子像素的衰减相对于R子像素、G子像素来说会小很多，这样会导致显示的画面偏冷，冷色调并不适合亚洲人观看。因此可以通过white tracking（WT，白平衡）技术来实现，提高R子像素的亮度并且降低B子像素的亮度，从而削弱画面偏冷的现象。
目前的white tracking技术是采用8bit→10bit的方法实现，但是该方法会占用驱动IC （integrated circuit，集成电路）内部的存储空间，增加驱动IC的数据处理工作。
综上，目前的white tracking白平衡的数据存储方式占用的存储空间大，会增加驱动IC的计算难度，进而导致驱动IC的处理效率差。

参照图2，本申请的一实施例提供一种数据处理方法，所述数据处理方法包括：
步骤S10，获取显示装置的色彩数据，并将所述色彩数据的灰阶数据以第一预设格式读取；
在本实施例中，TFT-LCD（Thin Film Transistor-Liquid Crystal Display，薄膜晶体管液晶显示器）之所以能显示不同的颜色与画面，是因为面板内有很多个R红色、G绿色、B蓝色子像素，这3个子像素可以在不同亮度下显示出不同的颜色。由于蓝色光的波长短，因此B子像素的衰减相对于R子像素、G子像素来说会小很多，这样会导致显示的画面偏冷，冷色调并不适合亚洲人观看。因此可以通过white tracking（WT，白平衡）技术来实现，提高R子像素的亮度并且降低B子像素的亮度，从而削弱画面偏冷的现象。在进入white tracking白平衡之前，获取显示装置显示画面的色彩数据，所述色彩数据（RGB数据）包括颜色数据、色度数据和/或灰阶数据等。在进入白平衡之前，所述色彩数据的灰阶数据以第一预设格式表示。所述第一预设格式可以是计算机可读的数据格式，例如二进制数据或者是16进制数据，或者是其他以数据大小限定的格式。
可选地，将所述色彩数据的灰阶数据转换为以满足所占存储空间为8bit的第一预设格式读取，所述第一预设格式为满足8bit条件的格式，即，当前的灰阶数据表示不从8bit转换为10bit，而是继续以8bit表示。所述进入白平衡之前的色彩数据的灰阶数据以Dm表示，Dm的大小为8bit。
步骤S20，在显示装置进入白平衡调节后，将所述色彩数据的灰阶数据以所述第一预设格式及第二预设格式读取。
在将色彩数据的灰阶数据转换为8bit的数据后，或者之前或者同时，监测显示装置是否进入白平衡模式，在显示装置进入白平衡调节后，要变换灰阶数据的表达方式，减小所述色彩数据的灰阶数据所占用的存储空间，将所述色彩数据的灰阶数据以所述第一预设格式及第二预设格式读取。所述第二预设格式可以是数值，也可以是一种计算机识别的数据格式，例如二进制或者16进制等，满足限定的占用存储空间的方式表示。
具体的，将所述色彩数据的灰阶数据以满足所占存储空间为5bit的第二预设格式读取。所述第二预设格式的数据读取公式为：Dwt=a*Dm+d，其中，a为常数，d≤32或者d≤2^5，Dwt为进入白平衡后的灰阶数据，Dm为以第一格式表示的灰阶数据（进入白平衡之前的灰阶数据表示方式）。a可以是4或者其他适合的根据需求设置的数值。
用Dm表示进入白平衡之前的色彩数据的灰阶数据，占用的存储空间为8bit而转入白平衡之后，占用的存储空间为5bit，大大缩减了占用的存储空间。
在一实施例中，图3所示为一种white tracking（WT白平衡）技术的功能模块图，图4所示为WT table（白平衡查找表）的一种示例，R红色、G绿色、B蓝色子像素的每个灰阶数据都是由8bit变成10bit，这样数据量会增加，增加IC的运算量。
图5所示为本申请一实施例中数据计算的方法，减少数据存储所占用的空间，原始的8bit数据Dm的4倍减去Dn，Dn≤2^5，这样WT table中的数据就可以根据Dn来表示，如图6所示，后续存储的WT Table中的Dn只有5bit，大大降低了数据运算量，提高了驱动IC的计算能力。
在本申请一实施例中，因进入白平衡调节的R红色子像素和B蓝色子像素的亮度，因此，在获取色彩数据时，只获取R和B子像素的色彩数据，而不获取G子像素的色彩数据，获取R和B子像素的灰阶数据，进一步降低色彩数据的灰阶数据所需占用的存储空间。
本实施例通过在进入白平衡之前用第一预设格式的Dm来表示色彩数据的灰阶数据，转入白平衡后采用第一预设格式和第二预设格式的灰阶数据表示，进一步减小占用的存储空间，有效避免驱动IC空间占用带来的问题，降低了驱动IC的计算难度，进而提高了驱动IC的处理效率。
在一实施例中，参考图7，所述获取显示装置的色彩数据的步骤包括：
步骤S11，确定当前显示装置的显示模式；
步骤S12，根据所述显示模式和当前显示的画获取显示装置的色彩数据。
在本实施例中，显示装置存在多种显示模式，例如，高清模式、节能模式等，不同显示模式下会色彩的要求和灰阶数据的要求不同。因此，在不同显示模式下对于冷暖色的要求也不同。在获取色彩数据时，确定当前显示装置的显示模式，根据所述显示模式和当前显示的画面获取显示装置的色彩数据。即，对应不同的显示模式，对色彩数据有一定的不同，提前建立不同模式下对色彩数据的补偿值的对应关系，在确定模式后，根据当前的模式查找对应的补偿值来补偿获取的色彩数据。
本实施例通过显示模式的不同，在不同显示模式下对色彩数据做出一定的补偿，使得获取的色彩数据更加准确，进而可以更好的调节白平衡。
在一实施例中，参考图8，所述在显示装置进入白平衡调节后，将所述色彩数据的灰阶数据以所述第一预设格式及第二预设格式读取，以减小所述色彩数据的灰阶数据所占用的存储空间的步骤之后，还包括：
步骤S30，确定所述灰阶数据的压缩比例；
步骤S40，按照所述压缩比例压缩所述灰阶数据，将压缩后的灰阶数据保存至存储器中。
之前的实施例中通过存储格式的调整，使得显示装置显示画面的色彩数据的灰阶数据存储所占用的空间降低，而在本实例中在存储数据至驱动IC之前，将需要的存储数据进行压缩，而压缩的比例提前确定，根据压缩比例压缩色彩数据的灰阶数据，进而进一步地降低存储所占用的存储空间。
具体的，参考图9，压缩比例的确定方式包括：
步骤S31，获取用户对色度的敏感性和亮度的敏感性；
步骤S32，根据色度的敏感性和亮度的敏感性确定预设压缩比例。
人眼的特性表明人眼对于亮度的敏感性远高于色度的敏感性，在数据压缩中我们可以利用人眼此特性的敏感度作为参考决定其压缩比例，即，先确定当前用户对色度的敏感性和亮度的敏感性，根据色度的敏感性和亮度的敏感性确定预设压缩比例，提前建立一个色度的敏感性和亮度的敏感性与预设压缩比例的映射关系，例如，色度的敏感性s1和亮度敏感性l1对应压缩比例y1；而色度的敏感性s2和亮度敏感性l2对应压缩比例为y2。通过色度和亮度的敏感度来确定预设压缩比例，使得压缩比例更加合适。
在本申请一实施例中，参考图10，所述方法，还包括：
步骤S50，在进入白平衡后，根据转换的色彩数据的灰阶数据，增强红色子像素的亮度以及降低蓝色子像素的亮度。
本实施例的过程为调节白平衡的方式，因为显示装置显示的颜色中R红色色调偏暖，而B蓝色色调偏冷，需要平衡这两种色调，在进入白平衡后，驱动IC中保存的5bit的色彩数据的灰阶数据，增强R子像素的亮度以及降低B子像素的亮度；而如何增强根据当前所需要的色调在当前的色彩数据的灰阶数据基础上做出补偿。提前建立的映射关系而确定，可以是一查找表，根据灰阶值的差异来确定补偿值，进行补偿，进而调节色调的差异，使得显示效果更好，符合用户的预期。
而在一实施例中，为了更加准确的调节显示色调，在不同模式下补偿值的设置存在差异，根据显示模式的不同而设置不同的补偿值。
可以理解的，为了满足不同用户的需求，因，不同用户对于色调的需求不同，提前设置用户类别，根据用户类别而设置不同的补偿值。
在一实施例中，在驱动IC中存储有数据解压缩的方式，根据之前数据的压缩将色彩数据的灰阶数据解压缩，根据解压缩后的数据完成白平衡的操作，调节显示画面的色调，符合用户的预期。
此外，本申请实施例还提出一种显示装置，所述显示装置包括显示面板和与显示面板连接的时序控制器，所述时序控制器中加载有数据处理控制装置，所述显示面板在所述时序控制器的控制下完成显示的白平衡操作，而时序控制器中存储的数据处理方式以上述实施例中的数据处理方法完成，该数据处理方法加载于数据处理装置，供时序控制器调用和启动完成数据处理，进而降低数据存储所占用的空间，降低成本以及提高时序控制器的控制效率。所述显示装置可以是电视、手机、pad、机台显示仪等移动或固定显示设备。本实施例的显示装置通过在进入白平衡之前用第一预设格式的Dm来表示色彩数据的灰阶数据，转入白平衡后采用第一预设格式和第二预设格式的灰阶数据表示，进一步减小占用的存储空间，有效避免驱动IC空间占用带来的问题，降低了驱动IC的计算难度，进而提高了驱动IC的处理效率。
此外，本申请实施例还提出一种计算机可读存储介质，计算机可读存储介质，所述计算机可读存储介质上存储有数据处理程序，所述数据处理程序被处理器执行时实现如上实施例所述的数据处理方法。
