显示装置及其色彩数据处理方法Display device and color data processing method thereof

技术领域technical field

本发明涉及颜色管理技术，尤其是一种显示装置及其色彩数据处理方法。The invention relates to color management technology, in particular to a display device and a color data processing method thereof.

背景技术Background technique

目前，以发光二极管(Light Emitting Diode，以下简称：LED)作为背光源的LED背光液晶显示器，由于具有显色性好、无汞环保、使用寿命长等优点，已经逐渐成为液晶显示领域发展的主流显示装置。LED背光液晶显示器的色彩还原性较高，目前已经可以达到国家电视系统委员会制式(NationalTelevision Systems Committee，以下简称：NTSC)的100％以上，可以给观众带来更加丰富的视觉享受。At present, LED-backlit liquid crystal displays using light-emitting diodes (Light Emitting Diode, hereinafter referred to as: LED) as the backlight have gradually become the mainstream in the field of liquid crystal display due to their advantages such as good color rendering, mercury-free environmental protection, and long service life. display device. The color reproduction of LED-backlit liquid crystal display is relatively high, and it can reach more than 100% of the National Television Systems Committee (National Television Systems Committee, hereinafter referred to as: NTSC) at present, which can bring richer visual enjoyment to the audience.

LED背光源选用红绿蓝三基色LED混光，通过调整红绿蓝三基色LED的电流来得到想要的白色背光源。因此，LED背光液晶显示器的显示色域的大小，取决于红绿蓝三基色LED的主波长以及与之匹配的彩膜能透过的主波长。为了尽可能增加LED背光液晶显示器的显示色域，在选用LED时，会尽量选用红光波长R≥630nm，绿光波长G≈520nm，蓝光波长B≤450nm。但是，在该波长情况下，显示器显示人的肤色时，会出现偏红的现象，感觉失真。The LED backlight uses red, green and blue three primary color LEDs to mix light, and the desired white backlight is obtained by adjusting the current of the red, green and blue three primary color LEDs. Therefore, the size of the display color gamut of the LED-backlit liquid crystal display depends on the dominant wavelength of the red, green and blue tri-color LEDs and the dominant wavelength that can be transmitted by the matching color filter. In order to increase the display color gamut of LED-backlit liquid crystal displays as much as possible, when selecting LEDs, the wavelength of red light R≥630nm, the wavelength of green light G≈520nm, and the wavelength of blue light B≤450nm will be selected as much as possible. However, in the case of this wavelength, when the monitor displays human skin color, there will be a reddish phenomenon, which feels distorted.

为解决上述问题，现有技术中采用的第一种方式是：选用红绿蓝三基色LED时进行控制，选择波长范围较小、能显示较小色域的红绿蓝三基色LED作为背光源，这样就会牺牲显示器的色彩还原性，导致成像不自然、不真实。In order to solve the above problems, the first method adopted in the prior art is to control when selecting red, green and blue tri-primary color LEDs, and select red, green and blue tri-primary color LEDs with a smaller wavelength range and a smaller color gamut as the backlight , This will sacrifice the color reproduction of the display, resulting in unnatural and unreal imaging.

现有技术中采用的第二种方式是：采用色彩管理系统，例如：符合国际色彩联盟(International Color Consortium，以下简称：ICC)颜色管理标准的系统等，建立设备的显色空间与标准颜色空间之间的一一对应关系，在接收到图像画面时，根据设备的显色空间与标准颜色空间之间的对应关系，将图像画面的标准颜色空间值转化到设备的显色空间值，从而在保证原有较大色彩还原性的基础上，最大限度地使显示的图像画面真实。但是，采用第二种方式时，需要依靠电脑加载的色彩管理模块的支持，成本高，操作复杂，而且不方便对液晶电视进行管理。The second method adopted in the prior art is: adopt a color management system, for example: a system that complies with the International Color Consortium (International Color Consortium, hereinafter referred to as: ICC) color management standard, etc., to establish the color rendering space and standard color space of the equipment The one-to-one correspondence between the image screens, according to the corresponding relationship between the color rendering space of the device and the standard color space, converts the standard color space value of the image screen into the color rendering space value of the device, so that in On the basis of ensuring the original maximum color reproduction, the displayed image is as real as possible. However, when the second method is adopted, it needs to rely on the support of the color management module loaded on the computer, which is costly, complicated to operate, and inconvenient to manage the LCD TV.

The standard color lookup table and the device color lookup table can be stored in thestorage module 104 for query by thecolor processing module 103 .

其中，设备颜色查找表可以通过MATLAB程序语言进行神经网络模拟计算得到。具体地，通过MATLAB程序语言进行神经网络模拟计算得到设备颜色查找表的一个实施例的流程如图3所示。图4所示为通过MATLAB程序语言进行神经网络模拟计算得到设备颜色查找表的一个原理图。同时参见图3与图4，通过MATLAB程序语言进行神经网络模拟计算得到设备颜色查找表包括以下步骤：Wherein, the device color lookup table can be obtained by performing neural network simulation and calculation through the MATLAB programming language. Specifically, the flow of an embodiment of obtaining the device color lookup table by performing neural network simulation calculation through the MATLAB programming language is shown in FIG. 3 . Fig. 4 shows a schematic diagram of the device color lookup table obtained by performing neural network simulation calculation through the MATLAB programming language. Referring to Fig. 3 and Fig. 4 at the same time, the device color lookup table obtained by performing neural network simulation calculation through the MATLAB programming language includes the following steps:

步骤301，利用色度计测量在显示器101的参数下，复数个(即：多个)红绿蓝色块RGB与各红绿蓝色块RGB分别对应的、由色度值x、y、z与亮度值Lv表示的目标颜色块xyzLv之间的对应关系RGB-xyzLv。Step 301, using a colorimeter to measure under the parameters of thedisplay 101, a plurality of (that is: multiple) red, green and blue blocks RGB correspond to each red, green and blue block RGB respectively, by chromaticity values x, y, z The corresponding relationship RGB-xyzLv between the target color block xyzLv represented by the brightness value Lv.

如图4，以A表示一个红绿蓝色块RGB，以A0表示该红绿蓝色块RGB对应的目标颜色块xyzLv，也即：目标值，测量复数组A与A0之间的对应关系，也即：RGB-xyzLv。As shown in Figure 4, A represents a red, green and blue block RGB, and A0 represents the target color block xyzLv corresponding to the red, green and blue block RGB, that is, the target value, and measures the correspondence between the complex array A and A0, That is: RGB-xyzLv.

步骤302，利用MATLAB程序语言建立初级神经网络，并通过测量得到的复数个对应关系RGB-xyzLv训练神经网络，获得符合预先设置的精度要求的目标神经网络。Step 302, using the MATLAB programming language to establish a primary neural network, and training the neural network through the measured plural correspondences RGB-xyzLv to obtain a target neural network that meets the preset accuracy requirements.

具体地，建立一个初级神经网络，给定输入A以后，通过该初级神经网络可以得到相应的输出A’，但是该输出A’与我们预先设置的目标值A0存在一定误差。通过比较A’与A0训练神经网络，即：调整初级神经网络的参数，使得输入A时，通过该调整后的神经网络得到与目标值A0误差变小的输出A”，并通过多次训练申请网络，使得输入A通过神经网络的输出与目标值A0误差达到预设的标准误差范围内。采用同样的方法，分别利用输入B与相应目标值B0、输入C与目标值C0、......来训练神经网络，直到网络训练完毕。使得通过该神经网络，任意给定一个输入X，都可以得到一个与相应的目标值X0的误差在预设的标准误差范围内的输出X’。Specifically, a primary neural network is established. After the input A is given, the corresponding output A' can be obtained through the primary neural network, but there is a certain error between the output A' and our preset target value A0. Train the neural network by comparing A' and A0, that is, adjust the parameters of the primary neural network so that when A is input, the adjusted neural network can obtain an output A" with a smaller error from the target value A0, and apply through multiple training Network, so that the error between the output of input A through the neural network and the target value A0 reaches the preset standard error range. Using the same method, use input B and the corresponding target value B0, input C and target value C0,... .. to train the neural network until the network is trained, so that through the neural network, any given input X can obtain an output X' whose error with the corresponding target value X0 is within the preset standard error range.

步骤303，利用步骤302获得的目标神经网络进行模拟计算，得到表示大量的(例如：20万个)红绿蓝色块RGB与相应目标颜色块xyzLv之间对应关系的RGB-xyzLv，也即：表示标准颜色空间与目标颜色信号之间对应关系的设备颜色查找表。Step 303, use the target neural network obtained instep 302 to perform simulation calculations, and obtain RGB-xyzLv representing the corresponding relationship between a large number of (for example: 200,000) red, green and blue blocks RGB and corresponding target color blocks xyzLv, that is: A device color lookup table representing the correspondence between standard color spaces and target color signals.

本发明实施例中，显示装置可以自身通过预先设置的标准颜色查找表与设备颜色查找表，对输入的红绿蓝颜色信号进行标准颜色查找和校正，在保证原有较大色彩还原性的基础上，保证了显示的图像画面真实性；并且，由于依靠显示装置自身实现，不需要单独加载色彩管理模块，采用本发明提供的显示装置作为LED背光液晶显示器，与现有技术相比，降低了颜色管理的成本，不需要单独操作，非常方便。In the embodiment of the present invention, the display device can perform standard color search and correction on the input red, green and blue color signals through the preset standard color lookup table and device color lookup table, on the basis of ensuring the original large color reducibility On the one hand, the authenticity of the displayed image picture is guaranteed; and, since the display device itself is used for realization, the color management module does not need to be loaded separately, and the display device provided by the present invention is used as an LED-backlit liquid crystal display, which reduces the The cost of color management does not need to be operated separately, which is very convenient.
