具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明提供一种液晶显示终端色域提升方法，在本发明液晶显示终端色域提升方法的第一实施例中，参照图8，该液晶显示终端色域提升方法包括：
步骤S10，获取液晶显示终端背光源对应可见光波段的频谱能量分布；
液晶显示终端显示不同颜色的画面，是通过RGB（红绿蓝）三基色加法原理，实现不同色彩的重现。因此，提升液晶显示终端的色彩表现力，即提高液晶显示终端的显示画质，主要通过调整该液晶显示终端背光源的RGB三基色的频谱能量分布以实现高色域（色域提高，显示的色彩更多、更鲜艳，从而显示画质更高）。
基于液晶显示终端背光源的显示硬件参数，获取对应的可见光波段（例如380nm至780nm）的频谱能量分布（即频谱图数据），例如，参照图1，一液晶显示终端LED背光源模组的频谱图，横向坐标单位为波长，纵向坐位单位为相对能量，其中，区域E为蓝基色波段（例如设置波长446nm为蓝基色波长，446nm前后20nm的波段为蓝基色波段），区域B为绿基色波段、区域D为红基色波段，区域A是蓝基色与绿基色之间的过渡波段，区域C为绿基色与红基色之间的过渡波段；由于区域A和区域C的光波能量会影响到RGB三基色的纯度，此外由于区域B的半高宽度值较大，相应地，绿基色纯度也较低，需要对该频谱能量分布进行调节以缩小RGB三基色的半高宽。
此外，在液晶显示终端未进行色域提升之前，其高色域背光源模组色域覆盖率如图2所示，三角形1在CIE 1931色坐标体系中的覆盖面积为NTSC 1953标准；三角形2所覆盖面积为未进行色域提升之前液晶显示终端的高色域背光源模组色域值。从三角形1和三角形2面积对比中，可知未进行色域提升之前液晶显示终端的高色域背光源模组，在绿色的色彩重现性最差。
步骤S20，根据频谱能量分布，在可见光波段中确定三基色波段；
三基色波段包括蓝基色波段、绿基色波段和红基色波段，根据液晶显示终端背光源的频谱能量分布（即频谱图），确定三基色的波长，并依据该三基色波长在可见光波段中确定三基色波段，例如蓝增益波长前后30nm波长区间为蓝基色波段、绿增益波长前后30nm波长区间为绿基色波段、红增益波长前后30nm波长区间为红基色波段。
步骤S30，过滤可见光波段中除三基色波段之外的过渡波段的可见光频谱能量，提升该三基色波段的可见光纯度，以提升液晶显示终端的色域值。
部分过滤或全部过滤液晶显示终端背光源的可见光波段中除三基色波段之外的过渡波段的可见光频谱能量，即降低了过渡波段的可见光频谱能量值，缩小了RGB三基色波段主波峰的半高度值，从而提升了该三基色波段的可见光纯度，实现了液晶显示终端的超高色域显示。此外，基于图1的频谱能量分布图，提出图3中用于过滤过渡波段的可见光频谱能量的频谱能量调整方案，在将图3频谱能量调整方案与图1的频谱能量分布图匹配后，如图4的基于可调频技术的匹配示意图，经过频谱能量过滤调整后，得到如图5所示频谱能量分布图，即液晶显示终端背光源的频谱能量分布经本发明调整后如图5所示，缩小了RGB三基色半高宽度值，提高了RGB三基色的纯度。参照图7，图7为液晶显示终端背光源经本发明提升色域值后对应的色域覆盖率，三角形1为NTSC 1953色域标准覆盖面积，三角形2为提升色域值后的液晶显示终端背光源的色域覆盖面积。从图7中可知，得益于可调频谱能量分布技术（即本发明液晶显示终端色域提升方法），液晶显示终端的RGB三基色纯度提升，色彩还原能力也得到提升。在CIE 1931色坐标体系中，经过本发明改善技术处理，三角形2的三个顶点，分别对应RGB三基色坐标点，往纯色RGB坐标点延展，即色彩表现力提升。
可选地，过滤可见光波段中过渡波段的频谱能量是基于可调频分布技术（即本发明液晶显示终端色域提升方法），以纳米级为单位，精确点对点调整液晶显示终端背光源的频谱能量值，从而控制该液晶显示终端的频谱分布，实现对不同背光源频谱分布的液晶显示终端频域的提升，丰富了液晶显示终端画面显示形态。具体地，通过调制背光源出光区域中不同颜色色粉比例和浓度，控制该背光源的可见光不同波段的能量穿透系数，从而改变原有背光源的频谱能量分布值；例如，要过滤除可见光中波长578nm至600nm的红绿光，则将背光源在波长578nm至600nm的能量穿透系数降为0，具体地，将背光源出光区域上红绿光对应区域的红绿色粉浓度调整至足够大以完全滤除红绿光。
在本实施例中，通过先获取液晶显示终端背光源对应可见光波段的频谱能量分布；然后根据频谱能量分布，在可见光波段中确定三基色波段；最后过滤所述可见光波段中除三基色波段之外的过渡波段的可见光频谱能量，缩小三基色波段的半高宽度值，提升该三基色波段的可见光纯度，从而背光源基于纯度更高的三基色可以显示更多颜色，从而提升液晶显示终端的色域值，提高了液晶显示终端的显示画质。
进一步地，在本发明液晶显示终端色域提升方法第一实施例的基础上，提出液晶显示终端色域提升方法的第二实施例，参照图9，在第二实施例中，步骤S30包括：
步骤S31，基于三基色波段，确定可见光波段中除三基色波段之外的过渡波段；
确定RGB三基色波段和液晶显示终端背光源的可见光波段，然后在可见光波段中剔除RGB三基色波段，剩下的波段作为过渡波段。
步骤S32，获取过渡波段可见光频谱能量的能量穿透系数；
该用于过滤可见光波段中过渡波段的可见光频谱能量的能量穿透系数可以是智能显示终端自动设置或用户根据需求设置，能量穿透系数越高，过滤掉过渡波段可见光频谱能量越少；能量穿透系数越低，过滤掉过渡波段可见光频谱能量越高。
步骤S33，根据能量穿透系数，过滤过渡波段的可见光频谱能量，提升该三基色波段的可见光纯度，以提升液晶显示终端的色域值。
根据获取的能量穿透系数，过滤对应比例的过渡波段的可见光频谱能量，例如若能量穿透系数为0，则滤除过渡波段的可见光频谱能量，从而提升该三基色波段的可见光纯度，提升了液晶显示终端的色域值。
在本实施例中，通过设置能量穿透系数，选择性地过滤对应比例的过渡波段的可见光频谱能量，从而可以根据液晶显示终端的实际显示需求调整三基色波段的可见光纯度，适当地提升液晶显示终端的色域值。当然，该能量穿透系数可以设置为0，即完全滤除过渡波段的可见光频谱能量。
进一步地，在本发明液晶显示终端色域提升方法第二实施例的基础上，步骤S33包括：
步骤S331，根据能量穿透系数，调整过渡波段的可见光在背光源对应出光区域对应颜色色粉的浓度，其中，色粉浓度越高过滤与该色粉颜色对应的可见光频谱能量越多；
步骤S332，基于色粉过滤过渡波段的可见光频谱能量，提升该三基色波段的可见光纯度，以提升液晶显示终端的色域值。
为辅助理解本实施例，举一例子辅助说明，例如，设过渡波段的可见光为红绿光，能量穿透系数为0（对应色粉浓度为Q），则在背光源红绿光的出光区域设置红绿色粉，该红绿色粉的浓度为Q，从而红绿色粉完全滤除红绿光的频谱能量，从而调整背光源出光区域设置与过渡波段可见光颜色相同且浓度与能量穿透系数对应的色粉，实现了对过渡波段的可见光频谱能量的过滤，提升该三基色波段的可见光纯度，提升了液晶显示终端的色域值。
进一步地，在本发明液晶显示终端色域提升方法第二实施例的基础上，提出液晶显示终端色域提升方法的第三实施例，参照图10，在第三实施例中，步骤S33包括：
步骤S34，基于人眼视见函数，确定亮度贡献波段；
步骤S35，根据能量穿透系数，过滤过渡波段中除该亮度贡献波段之外波段的可见光频谱能量，提升该三基色波段的可见光纯度，以提升液晶显示终端的色域值。
基于人眼视见函数可知，在可见光谱中，人眼对光谱中部（黄绿色）最敏感，越靠近光谱两端，越不敏感。在人眼视见函数中，在波长555nm附近的光（黄绿光）人眼感知的亮度是最高的。因此，参照图6中提升液晶显示终端色域值的频谱能量调整方案与人眼视见函数的匹配效果，在进行本发明过滤过渡波段的可见光频谱能量，提升液晶显示终端色域值的同时，需要考虑过渡波段与人眼视见函数中人眼感知亮度最高的亮度贡献波段之间匹配关系，以确保液晶显示终端光效衰减最小化；即在对亮度贡献值最大的波段（即亮度贡献波段，例如亮度贡献波段为555nm前后30nm的波段），缩小频谱能量调整幅度以确保液晶显示终端的显示亮度。
在本实施例中，基于人眼视见函数，在可见光波段中确定亮度贡献波段，缩小过渡波段与亮度贡献波段重叠波段的频谱能量调整幅度，即增大背光源对过渡波段与亮度贡献波段重叠波段的可见光的能量穿透系数，减少对背光源对过渡波段与亮度贡献波段重叠波段可见光的频谱能量的过滤，在提升液晶显示终端色域值的基础上，最大限度地保证了光效值，确保液晶显示终端实现高亮度高色域的画质。
进一步地，在本发明液晶显示终端色域提升方法第三实施例的基础上，步骤S35包括：
步骤S351，确定过渡波段中除该亮度贡献波段之外波段的可见光在背光源出光区域的投射区域；
步骤S351，根据能量穿透系数，调整背光源出光区域的投射区域中与过渡波段中除该亮度贡献波段之外波段的可见光颜色对应色粉的浓度，其中，色粉浓度越高过滤与该色粉颜色对应的可见光频谱能量越多；
步骤S351，基于色粉过滤过渡波段中除该亮度贡献波段之外波段的可见光频谱能量，提升该三基色波段的可见光纯度，以提升液晶显示终端的色域值。
在确定液晶显示终端背光源的亮度贡献波段之后，确定过渡波段中除该亮度贡献波段之外波段的可见光在背光源出光区域的投射区域；然后根据能量穿透系数，调整背光源出光区域的投射区域中与过渡波段中除该亮度贡献波段之外波段的可见光颜色对应色粉的浓度，从而利用该色粉过滤过渡波段中除该亮度贡献波段之外波段的可见光频谱能量；即增大背光源对过渡波段与亮度贡献波段重叠波段的可见光的能量穿透系数，减少对背光源对过渡波段与亮度贡献波段重叠波段可见光的频谱能量的过滤，在提升液晶显示终端色域值的基础上，最大限度地保证了光效值，确保液晶显示终端实现高亮度高色域的画质。
