本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
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。
本发明实施例的主要解决方案是：液晶显示模组的色彩生成装置先按照预设的顺序依次获取各个待显示像素点的灰度值；然后，在获取到每个像素点的灰度值后，控制三基色光源以预设切换频率依次发射不同的基色光，并控制像素点的显示位置对应的薄膜晶体管开关开启；再根据当前待显示的像素点的灰度值以及像素点的显示位置生成对应的脉冲信号；最后，将脉冲信号发送至驱动电路，以供驱动电路根脉冲信号加载对应的脉冲电流至对应的薄膜晶体管中。
由于现有技术中，液晶显示屏中含有滤光膜，而滤光膜的制作成本较高，使得液晶显示屏的制作成本较高。
本发明提供一种解决方案，液晶显示模组通过控制三基色光源的不同基色在一定时间内依次显示在显示屏的同一点，使得液晶屏不需要滤光膜即能生成设定的色彩，从而使得液晶显示模组的成本降低。
如图1和图2，图1为液晶显示模组的爆炸图，图2为第一透明电极40的正视图。
参照图1、图2和图3，对液晶显示模组进行详细的说明。
液晶显示模组由N走向（竖直方向）的三基色光源10、下偏光片20、第一玻璃基板30、第一透明电极40、液晶50、第二透明电极60、第二玻璃基板70和上偏光片80依次连接构成的。
靠近液晶50的第一透明电极40的一侧设置走线电极43与信号电极44，走线电极43与信号电极44相互交错构成多个封闭区域，每个封闭区域设置有薄膜晶体管41，薄膜晶体管41通过薄膜晶体管开关42可与走线电极43、信号电极44连通，走线电极43与信号电极44构成驱动电路的一部分。
当薄膜晶体管开关42开启时（开关处于闭合状态），该薄膜晶体管开关42对应的薄膜晶体管41中产生电流，使得该薄膜晶体管41对应的封闭区域与第二透明电极60之间产生感应电场，使得感应电场内的液晶分子（液晶分子处于第一透明电极40与第二透明电极60之间）进行定向排列，从而使得光在液晶分子中的折射角度改变，进而改变光穿透液晶分子的透射率。
参照图3，图3为本发明液晶显示模组的色彩生成方法的第一实施例，所述液晶显示模组的色彩生成方法包括以下步骤：
步骤S10，按照预设的顺序依次获取各个待显示像素点的灰度值；
本发明是利用时间混色法的方法使得液晶显示模组成像的，该方法利用人眼的视觉惰性（对于中等亮度的光刺激，视觉暂留时间约为0.05s至0.2s，视觉暂留时间即为视网膜的视神经的反应时间），只要液晶显示模组将三种基色光顺序的出现在显示屏的同一表面的同一处，人眼会感觉这三种基色光是同时出现，并捕获到三种基色光相加所得的色彩。
液晶显示模组的显示屏（第二玻璃基板）可分为多个显示区域，每个显示区域对应一个薄膜晶体管，当显示屏需要显示画面时，液晶显示模组会按照显示屏的显示区域数量以及液晶显示模组的色彩生成方法将显示换面划分为对应的像素点，而本实施中液晶显示模组的色彩生成方法采用时间换色法，每一个像素点对应一个显示屏的显示区域，即每个像素点对应相应的显示位置。每一个像素点代表一个色彩，而每个色彩由红、绿和黄三种基色组成，而且每种基色都具有相应的灰度值，基色的灰度值由基色通过液晶分子的透射率决定，也就是说根据液晶显示模组所需显示的画面决定了每个像素点显示的色彩，而像素点所需显示的色彩的组成基色具有对应的灰度值，这就意味着液晶显示模组需要多次调节穿透液晶分子的基色光的透射率，为了避免显示屏杂乱无章的显示画面，液晶显示模组必须对基色的灰度值调整进行排序。此，显示屏上的与像素点对应的显示位置可以进行排序，使得显示屏能够连贯的显示画面，在当一个显示位置的色彩生成之后，立刻进行下一个顺序的显示位置的色彩生成，这样的话可以画面能够有规则的连贯呈现出来。本实施例中预设顺序指的是像素点对应显示位置的色彩生成顺序。
在显示屏需要显示画面时，液晶显示模组会将显示画面按照显示屏的显示区域划分为相应的区域，画面每个区域为一个像素点，液晶显示模组会根据像素点获取相应的色彩，然后根据色彩分析出色彩的基色组成，并确定色彩中各个基色的灰度值。
步骤S20，在获取到每个像素点的灰度值后，控制三基色光源以预设切换频率发射不同的基色光，并控制像素点的显示位置对应的薄膜晶体管开关开启；
三基色光源指的是红、绿和黄三种光源的基色光，三基色光源会依次且每次只发射单一的基色光，并且三基色光源会持续切换发射的基色光，比如，三基色光源有红、绿和蓝三种基色光。
本实施例中的液晶显示模组采用的色彩生成方法为时间混色法，那么三基色光源每切换一轮（红、绿、蓝三种基色光）基色光的时长应该是小于或等于人眼残留影像的时间，但是为了使得像素点对应的显示位置生成的色彩具有连贯性，那么三基色光源每切换一轮基色光的时长应该远远小于人眼残留影像，在本实施中三基色光源的基色的预设切换频率为180Hz，三基色光源切换一轮基色光的时长约为0.0112S，远小于人眼残留影像时长0.05s-0.2s，当然，三基色光源的基色切换频率还可以是其他任意合适的数值。
需要说明的是，因显示屏的每一个显示位置对应一个薄膜晶体管，而显示位置的色彩时有序的生成，所以在某一显示位置进行色彩的生成时，与该显示位置对应的薄膜晶体管开关开启，其他的薄膜晶体管开关关闭（开关处于断开状态）。
因为每一个像素点的色彩生成需要三种基色光的合成，每种基色光都需要进行灰度值的调节，即每个像素点中的色彩的生成需要历经三次基色灰度值的调节，可将基色灰度值的调节频率对应薄膜晶体管开关的开启频率，而基色灰度至的调节频率对应三基色光源的基色预设切换频率，所以可将薄膜晶体管开关的开启频率与三基色光源的基色预设切换频率同步，在薄膜晶体开关开启时，三基色光源发射基色光，当然在某一显示位置的色彩生成过程中，薄膜晶体管开关可以一直处于开启状态，只需根据脉冲信号调节薄膜晶体管开关的开度即可完成基色灰度值的调节。
步骤S30，根据当前待显示的像素点的灰度值以及像素点的显示位置生成对应的脉冲信号；
液晶显示模组的液晶指的是液晶分子层，液晶介于液态与结晶态之间的一种物质状态，是一种棒状分子，液晶分子的二端具有极性，可以在不同的电压下扭转不同的角度，而且液晶分子具有折射光的作用，所以液晶分子层在不同电压的电场下扭转不同角度决定光的透射率，所以液晶分子层通过调节基色光的透射率来调节显示屏的基色灰度值。
在液晶显示模组获取到像素点中的色彩的各个基色灰度值后，液晶显示模组会依据基色的灰度值生成对应的脉冲信号，每个脉冲信号可对薄膜晶体管开关的开度进行相应的调整，使得薄膜晶体管内的电流为设定的电流值，从而使得液晶分子处于设定电压的感应电场内，进而使得液晶分子扭转相应的角度以确定基色光的透射率，最终使得穿透液晶分子层的基色光为预设的灰度值合成色彩。
步骤S40，将脉冲信号发送至驱动电路，以供驱动电路根据脉冲信号加载对应的脉冲电流薄膜晶体管；
驱动电路上设有信号电极和走线电极，走线电极为闭合回路，在液晶显示模组工作时，走线电极内有电流流经。当在驱动电路接收到脉冲信号的同时，液晶显示模组会将与脉冲信号对应的薄膜晶体管开关开启，从而使得与薄膜晶体管开关对应的薄膜晶体管形成一个小的闭合回路，从而使得走线电极的电流可以通过薄膜晶体管开关流入薄膜晶体管，薄膜晶体管开关会根据脉冲信号控制其开关的开度从而控制流入薄膜晶体管电流的大小，从而使得液晶分子所处的感应电场的电压值为设定的电压值，达到控制基色灰度值调节的目的。
现有的液晶显示模组的色彩生成方法采用空间混色法，空间混色法时利用人眼空间细节分辨能力差的特点，将三种基色光在同一平面的对应位置充分靠近，只要三个基色光点足够小且充分接近，人眼在离开显示屏一定距离后，会感觉三种基色光混合后的所具有的颜色，因而液晶显示模组需要含有三种基色的白色光作为背光源，为了去除白色光的三种基色外的光，液晶显示模组需要使用滤光膜对白光进行过滤，所以滤光膜是采用空间混色法生成色彩的液晶显示模组中不可缺少的重要组件，而滤光膜的成本较高，从而使得液晶显示模组的整体成本提高。
需要说明的是，本实施中液晶显示模组的色彩生成方法采用的是时间混色法，即液晶显示模组在一个像素点上顺序显示三种不同的基色以生成色彩，可以理解为，液晶显示模组显示屏的一个像素点即可生成一个色彩，不同于而液晶显示模组采用空间混色法的色彩生成方法，位置相近的三个像素点才能够生成一个色彩，在液晶显示模组的显示屏像素点数量相同的情况下，采用时间混色法的液晶显示模组的显示屏的分辨率是采用空间混色法的液晶显示模组的显示屏的分辨率的三倍。
本实施例提供的技术方案中，液晶显示模组采用三基色光源在像素点对应的显示位置上顺序的显示不同的基色以生成色彩，并且控制不同基色在显示位置的显示时间，使得液晶显示模组能够生成设定的色彩，使得液晶显示模组无需采用滤光膜进行色彩的过滤即可生成设定的色彩，从而降低了液晶显示模组的成本。
参照图4，图4为本发明液晶显示模组的色彩生成方法的第二实施例，上述实施例，所述步骤S40之后，还包括：
步骤S50，在检测到三基色光源的光源出现故障时，控制液晶显示模组中的所有薄膜晶体管开关开启，且控制三基色光源持续发射设定的基色光；
在像素点对应的显示位置生成相应的色彩后，液晶显示模组会检测该色彩的基色光数量是否与预设色彩基色光数量一致。当三基色光源中光源出现问题时，像素点对应的显示位置生成的色彩会与设定的色彩颜色的像素单元不一致，从而使得液晶显示模组判定三基色光源的光源出现问题，此时，液晶显示模组会控制全部的薄膜晶体管的开关开启，并控制三基色光源停止切换光源，并持续发射设定的基色光，设定的基色光可为红光（三基色光源的红色光源未出现问题的情况下），以提醒用户对液晶电视进行维修。
本实施例提供的技术方案中，当三基色光源的光源出现问题时，通过控制所有薄膜晶体管开关开启，并控制三基色光源持续发射设定的基色光，使得液晶屏的全屏显示该设定基色光的颜色，以提醒用户对液晶显示模组进行维修。
参照图5，图5为本发明液晶显示模组的色彩生成装置程序模块是示意图，所述液晶显示模组的色彩生成装置包括：获取程序100、控制程序200、生成程序300和发送程序400；所述获取程序100，用于按照预设的顺序依次获取各个待显示像素点的灰度值；
所述获取程序100，按照预设的顺序依次获取各个待显示像素点的灰度值；
本发明是利用时间混色法的方法使得液晶显示模组成像的，该方法利用人眼的视觉惰性（对于中等亮度的光刺激，视觉暂留时间约为0.05s至0.2s，视觉暂留时间即为视网膜的视神经的反应时间），只要液晶显示模组将三种基色光顺序的出现在显示屏的同一表面的同一处，人眼会感觉这三种基色光是同时出现，并捕获到三种基色光相加所得的色彩。
液晶显示模组的显示屏（第二玻璃基板）可分为多个显示区域，每个显示区域对应一个薄膜晶体管，当显示屏需要显示画面时，液晶显示模组会按照显示屏的显示区域数量以及液晶显示模组的色彩生成方法将显示换面划分为对应的像素点，而本实施中液晶显示模组的色彩生成方法采用时间换色法，每一个像素点对应一个显示屏的显示区域，即每个像素点对应相应的显示位置。每一个像素点代表一个色彩，而每个色彩由红、绿和黄三种基色组成，而且每种基色都具有相应的灰度值，基色的灰度值由基色通过液晶分子的透射率决定，也就是说根据液晶显示模组所需显示的画面决定了每个像素点显示的色彩，而像素点所需显示的色彩的组成基色具有对应的灰度值，这就意味着液晶显示模组需要多次调节穿透液晶分子的基色光的透射率，为了避免显示屏杂乱无章的显示画面，液晶显示模组必须对基色的灰度值调整进行排序。此，显示屏上的与像素点对应的显示位置可以进行排序，使得显示屏能够连贯的显示画面，在当一个显示位置的色彩生成之后，立刻进行下一个顺序的显示位置的色彩生成，这样的话可以画面能够有规则的连贯呈现出来。本实施例中预设顺序指的是像素点对应显示位置的色彩生成顺序。
在显示屏需要显示画面时，液晶显示模组会将显示画面按照显示屏的显示区域划分为相应的区域，画面每个区域为一个像素点，液晶显示模组会根据像素点获取相应的色彩，然后根据色彩分析出色彩的基色组成，并确定色彩中各个基色的灰度值。
所述控制程序200，用于在获取到每个像素点的灰度值后，控制三基色光源以预设切换频率发射不同的基色光，并控制像素点的显示位置对应的薄膜晶体管开关开启；
三基色光源指的是红、绿和黄三种光源的基色光，三基色光源会依次且每次只发射单一的基色光，并且三基色光源会持续切换发射的基色光，比如，三基色光源有红、绿和蓝三种基色光。
本实施例中的液晶显示模组采用的色彩生成方法为时间混色法，那么三基色光源每切换一轮（红、绿、蓝三种基色光）基色光的时长应该是小于或等于人眼残留影像的时间，但是为了使得像素点对应的显示位置生成的色彩具有连贯性，那么三基色光源每切换一轮基色光的时长应该远远小于人眼残留影像，在本实施中三基色光源的基色的预设切换频率为180Hz，三基色光源切换一轮基色光的时长约为0.0112S，远小于人眼残留影像时长0.05s-0.2s，当然，三基色光源的基色切换频率还可以是其他任意合适的数值。
需要说明的是，因显示屏的每一个显示位置对应一个薄膜晶体管，而显示位置的色彩时有序的生成，所以在某一显示位置进行色彩的生成时，与该显示位置对应的薄膜晶体管开关开启，其他的薄膜晶体管开关关闭（开关处于断开状态）。
因为每一个像素点的色彩生成需要三种基色光的合成，每种基色光都需要进行灰度值的调节，即每个像素点中的色彩的生成需要历经三次基色灰度值的调节，可将基色灰度值的调节频率对应薄膜晶体管开关的开启频率，而基色灰度至的调节频率对应三基色光源的基色预设切换频率，所以可将薄膜晶体管开关的开启频率与三基色光源的基色预设切换频率同步，在薄膜晶体开关开启时，三基色光源发射基色光，当然在某一显示位置的色彩生成过程中，薄膜晶体管开关可以一直处于开启状态，只需根据脉冲信号调节薄膜晶体管开关的开度即可完成基色灰度值的调节。
所述控制程序200，还用于在检测到三基色光源的光源出现故障时，控制液晶显示模组中的所有薄膜晶体管开关开启，且控制三基色光源持续发射设定的基色光；
在像素点对应的显示位置生成相应的色彩后，液晶显示模组会检测该色彩的基色光数量是否与预设色彩基色光数量一致。当三基色光源中光源出现问题时，像素点对应的显示位置生成的色彩会与设定的色彩颜色的像素单元不一致，从而使得液晶显示模组判定三基色光源的光源出现问题，此时，液晶显示模组会控制全部的薄膜晶体管的开关开启，并控制三基色光源停止切换光源，并持续发射设定的基色光，设定的基色光可为红光（三基色光源的红色光源未出现问题的情况下），以提醒用户对液晶电视进行维修。
所述生成程序300，用于根据当前待显示的像素点的灰度值生成对应的脉冲信号；
