【具体实施方式】
参阅图1和图2，图1是本发明触控式显示模组第一实施方式的结构示意图，图2是图1所示的显示模组第一实施方式中第一条状电极和第二条状电极的结构示意图，本实施方式提供了一种显示模组100，包括上基板101、下基板102、液晶层103以及控制芯片104。
其中，上基板101与下基板102相对设置，液晶层103设置于上基板101与下基板102之间；在上基板101面对下基板102的一侧设置有第一条状电极105，在下基板102面对上基板101的一侧设置有第二条状电极106；第一条状电极105与第二条状电极106延伸方向相互交叉。
为了在3D显示时有较大的视角，本实施方式中液晶层103厚度为100um，上基板101和下基板102均为0.5mm厚的玻璃基板，ITO膜层作为导电电极覆盖在玻璃基板上，其具有导电性好、透明度高的优点。其他实施方式中，可以将液晶层103厚度设置为50um、30um或20um，对于液晶层103的厚度在此不作限定，应根据实际使用情况，即使用时不同大小的视角要求，相应的设置不同厚度的液晶层。
由于最终光线需要通过显示模组实现显示的目的，因此上基板101和下基板102选用透明材料，由于玻璃基板以较为成熟，并且也能够实现较高的透光率，因此本实施方式中选用玻璃基板。当然若是追求更加轻量化的设计，也可选用透明塑料或其他透明高分子材料等。当前，已形成量产的玻璃基板按厚度分大致有以下几种规格：2.0mm、1.1mm、0.7mm、0.5mm、0.4mm和0.3mm， 考虑到成本及使用要求，本实施方式中选用0.5mm厚度的玻璃基板。技术人员也可根据实际需求选取其他厚度的玻璃基板，或自己定制一定厚度的玻璃基板如0.2mm或3.0mm等。
本实施方式中，ITO膜层覆盖在玻璃基板上形成条状电极，并且第一条状电极105与第二条状电极106延伸方向相互交叉。ITO膜层的主要成分为氧化铟锡，其中氧化铟透过率高、氧化锡导电性强。若显示模组对于光透过率要求不高时，也可以使用导电胶水、导电胶条等。
控制芯片104连接第一条状电极105以及第二条状电极106。
本实施方式中，控制芯片104与第一条状电极105和第二条状电极106的连接采用wire bonding工艺，即细金属线(直径大约3um)以超声焊或热压焊的方式连接控制芯片104的电路和第一条状电极105或第二条状电极106。具体请参阅图3，图3是图1所示的显示模组第一实施方式中控制芯片与第一条状电极或第二条状电极连接方式的示意图。在此，对于连接所采用的工艺方法不做限制。
显示模组100具有两种显示模式：3D显示和2D显示。在3D显示时，控制芯片104驱动第一条状电极105和第二条状电极106，进而实现液晶透镜或液晶光栅功能。
本实施方式中，控制芯片104驱动第一条状电极105和第二条状电极106间产生电位差，以使液晶层103实现液晶透镜功能。由于液晶层103中的液晶分子具有分子势能向最低状态变化的特性，即液晶分子的长轴方向与外加电场的场强方向一致。基于此原理，当向液晶层103施加电场时能够实现液晶透镜功能。具体请参阅图4，图4是图1所示的显示模组第一实施方式中液晶分子沿着电场线方向偏转以实现液晶透镜功能的示意图。其中，控制芯片104对第一条状电极105和第二条状电极106施加电压，以形成电场，并使第二条状电极106处于Com电位；液晶层103中的液晶分子在电场的作用下发生偏转形成类似柱透镜的结构，继而实现对光的会聚功能。
在液晶层103为柱透镜结构的情况下，光线能够通过液晶层103分别传输至人的左眼和右眼，即实现了3D显示。具体请参阅图5，图5是图1所示的显示模组第一实施方式中液晶层为柱透镜结构的情况下实现3D显示的原理示意图。此时，能使左眼图像的光线会聚至人的左眼，右眼图像的光线会聚至人的右眼，进而实现3D显示。
在其他实施方式中，控制芯片104还可驱动第一条状电极105和第二条状电极106间产生电位差，以使液晶层103实现液晶光栅功能。即液晶分子在电场作用下形成类似狭缝光栅的结构，继而使显示面板奇像素列发出的左眼图像传输至左眼，偶像素列发出的右眼图像传输至右眼，进而实现3D显示。
在2D显示时，控制芯片104驱动第一条状电极105和第二条状电极106，进而实现对触控操作进行定位的功能。
具体实现触控操作定位有两种工作方式，即自电容或互电容。对于自电容工作方式，具体请参阅图6和图7，图6是图1所示的显示模组第一实施方式中自电容工作方式中向第一条状电极和第二条状电极施加扫描信号的示意图，图7是图1所示的显示模组第一实施方式中第一条状电极和第二条状电极自电容工作方式的电路示意图。
采用自电容工作方式，控制芯片104对第一条状电极105和第二条状电极106输入扫描信号Input 701，第一条状电极105和第二条状电极106同时接收触控信号Output 702，对于第一条状电极105的自电容Cr703和第二条状电极106的自电容Ct704进行检测，其中自电容是电极与地构成的电容。若第一条状电极105数量为m，第二条状电极106数量为n，则需要检测的自电容数量为m+n。当发生触控时，触控点所在的第一条状电极105和第二条状电极106分别接收到电容变化的信号，因此可以分别确定触控点所在的第一条状电极105和第二条状电极106，继而推出两条状电极的交叉点即触控点，采用此工作方式，多点触控时，容易出现触控点不确定的问题，例如两点触控时，同时确定两条第一条状电极105和第二条状电极106，然而他们的交叉点有四个点，因此无法确定触控点到底是哪两个。
对于互电容工作方式，具体请参阅图8和图9，图8是图1所示的显示模组第一实施方式中互电容工作方式中向第一条状电极和第二条状电极施加扫描信号的示意图，图9是图1所示的显示模组第一实施方式中第一条状电极和第二条状电极互电容工作方式的电路示意图。
采用互电容的工作方式，控制芯片104对第二条状电极106输入扫描信号Input 901，第一条状电极105同时接收触控信号Output 902，对于第一条状电极105和第二条状电极106交汇处的互电容Cm 903进行检测，其中互电容903是两电极形成的电容。若第一条状电极105数量为m，第二条状电极106数量为n，则需要检测的互电容数量为m×n。当发生触控时，根据检测每个交汇点的电容 值即可确定触控点。采用此工作方式，需要检测的点过多，工作效率较低。
为了真正实现多点触控，本实施方式中采用互电容的工作方式。其他实施方式中也可以选自电容的工作方式，或自电容和互电容结合的工作方式。
区别于现有技术，本实施方式触控式显示模组包括相对设置的上下基板以及上下基板之间的液晶层，并在上基板和下基板上分别设置有相互交叉的条状电极，通过控制芯片对两条状电极进行驱动控制，使得液晶层呈现透镜或光栅效果，继而显示模组能够实现3D显示；且在不需要3D显示，而进行2D显示时，对显示模组实现复用，即触控芯片以另一种方式驱动控制两条状电极，使显示模组实现对触控操作进行定位的功能。本实施方式能够进行3D显示，并且2D显示时不增加触控层即能实现触控定位功能，进而利于显示模组的通透率及其轻薄化设计。
请参阅图10和图11，图10是本发明触控式显示模组第二实施方式的结构示意图，本实施方式提供一种显示模组200，包括上基板201、下基板202、液晶层203、以及控制芯片204。
其中，上基板201与下基板202相对设置，液晶层203设置于上基板201与下基板202之间；在上基板201面对下基板202的一侧设置有第一条状电极205，在下基板202面对上基板201的一侧设置有第二条状电极206；第一条状电极205与第二条状电极206延伸方向相互交叉。
控制芯片204连接第一条状电极205以及第二条状电极206，在3D显示时，控制芯片204驱动第一条状电极205和第二条状电极206，进而实现液晶透镜或液晶光栅功能。在2D显示时，控制芯片204驱动第一条状电极205和第二条状电极206，进而实现对触控操作进行定位的功能。
本实施方式中上基板201、下基板202、液晶层203、控制芯片204、第一条状电极205以及第二条状电极206的结构及设置均类似于触控式显示模组第一实施方式，在此不再赘述。
需要进一步说明，在本实施方式中，第一条状电极205和第二条状电极206延伸方向相互垂直。两电极相互垂直设置更利于触控操作时的定位。
任意相邻的两条第一条状电极205之间的间隔相同，其间隔距离为第一距离d1；任意相邻的两条第二条状电极206之间的间隔相同，其间隔距离为第二距离d2；第一距离d1大于第二距离d2；所有的第一条状电极205的宽度相同，其宽度为第一宽度c1；所有的第二条状电极206的宽度相同，其宽度为第二宽 度c2；第一宽度c1小于第二宽度c2。
第二宽度c2设置的较大且第二距离d2设置较小是为了不影响3D显示过程中上下基板之间形成的电场。若将第一宽度c1和第二宽度c2设置为相同，且第一距离d1和第二距离d2也设置为相同，则不容易形成有规律的电场，即无法有效的实现液晶透镜或液晶光栅的功能。
区别于现有技术，本实施方式触控式显示模组包括相对设置的上下基板以及上下基板之间的液晶层，并在上基板和下基板上分别设置有相互交叉的条状电极，通过控制芯片对两条状电极进行驱动控制，使得液晶层呈现透镜或光栅效果，继而显示模组能够实现3D显示；且在不需要3D显示，而进行2D显示时，对显示模组实现复用，即触控芯片以另一种方式驱动控制两条状电极，使显示模组实现对触控操作进行定位的功能。本实施方式能够进行3D显示，并且2D显示时不增加触控层即能实现触控定位功能，进而利于显示模组的通透率及其轻薄化设计。进一步的，本实施方式中第二条状电极相对于第一条状电极设置了较宽的宽度以及较窄的间隔距离，能够更好地实现液晶透镜功能。
请参阅图11，图11是本发明触控式显示装置第一实施方式的结构示意图，本实施方式提供一种显示装置300，包括显示模组301和显示面板302。
其中显示模组301包括上基板3011、下基板3012、液晶层3013、控制芯片3014、第一条状电极3015以及第二条状电极3016。本实施方式中的显示模组301类似于第二实施方式中的显示模组200，在此也不再赘述。
显示面板302设置在显示模组301下方，在进行3D显示时，显示面板302分别发送左眼3D图像和右眼3D图像，经过显示模组301继而分别传送至人的左眼和右眼，呈现3D显示效果。在进行2D显示时，显示面板302发送2D图像，经过显示模组302传送至人眼，呈现2D显示效果。
本实施方式中，显示面板为液晶LCD显示面板，其他实施方式中还可以选用有机电致发光OLED显示面板、等离子体PDP显示面板或阴极射线CRT显示面板。
区别于现有技术，本实施方式中显示装置实现3D显示时，显示面板分别发送左眼3D图像和右眼3D图像，同时显示模组中的控制芯片驱动两条状电极，使得液晶层呈现透镜或光栅效果，继而使左眼3D图像传送到人的左眼，右眼3D图像传送到人的右眼，实现3D显示；在不需要3D显示，而进行2D显示时，显示模组中控制芯片以另一种方式驱动控制两条状电极，使显示模组实现对触 控操作进行定位的功能。本实施方式能够在能够进行3D显示，并且2D显示时不增加触控层即能实现触控定位功能，进而利于显示模组的通透率及其轻薄化设计。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
