具体实施方式
为使本申请的上述目的、特征和优点能够更加明显易懂，下面结合附图对本申请的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本申请。但是本申请能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本申请内涵的情况下做类似改进，因此本申请不受下面公开的具体实施例的限制。
在一个实施例中，如图1和图2所示，提供了一种触控基板100，该触控基板100包括触控检测区域110和传感检测区域120。其中，触控检测区域110和传感检测区域120没有交叠，图1和图2示出了两个区域的两种设置方式，只用于说明两个区域之间的关系，并不用于限定两个区域的具体位置。
在本实施例中，如图3所示，触控检测区域110设置有触控电极111，触控电极111包括纵横交错的触控感应电极112和触控驱动电极114，其中，触控感应电极112和触控驱动电极114可以由ITO(Indium Tin Oxide,铟 锡氧化物)薄膜制成，且触控感应电极112和触控驱动电极114的位置可以互换。如图3中灰色阴影所示，在触控感应电极112和触控驱动电机114的交叠处会形成感应电容。进一步的，触控感应电极112和触控驱动电机114通过信号线与信号检测芯片电连接，信号检测芯片通过检测感应电容的容量变化即可确定触控基板上被触碰的位置并计算出其具体坐标，以此识别触控信号。
在本实施例中，传感检测区域120设置有传感电极，传感电极与触控电极类似，也是块状电极，并且同样通过信号线与信号检测芯片电连接。传感电极可以感应到不断变化的环境信号如环境光信号或距离信号，并将环境信号转换为电学信号，继而通过信号线将电学信号传导给信号检测芯片。进一步的，信号检测芯片通过信号比对即可识别出环境信号的类别和强弱，并通过检测结果指导显示装置进行相应的动作，例如指导显示装置自动调整显示面板的显示亮度或自动调整麦克风音量等等。
上述触控基板，通过在一个基板上设置不同的检测区域，并在不同的检测区域上分别设置触控电极和传感电极，使同一个触控基板既可以识别触控信号也可以识别环境信号，充分利用了触控基板的空间，节约了环境传感器的放置空间，使显示面板的窄边框设计易于实现。
在一个实施例中，如图1和图2所示，传感检测区域120位于触控检测区域110的一侧，且触控检测区域110与传感检测区域110的相邻处设置有第一固定电位线130。在本实施例中，第一固定电位线130的作用在于屏蔽触控电极和传感电极之间的信号传递，其形状可以不是如图1或图2中规则的直线或曲线，但第一固定电位线130须将两个区域完全的分隔开，以阻隔 两个区域内的不同电极的信号干扰。
在一个实施例中，如图4所示，传感检测区域120内设置的传感电极为距离传感电极121，距离传感电极121的排布方式与触控电极111的排布方式相同，同样包括了纵横交错的感应电极和驱动电极，但距离传感电极121的单个感应电极122和单个驱动电极124尺寸略大于触控电极111的单个感应电极112和单个驱动电极114尺寸且可以只排布一层电极。进一步的，距离传感电极121的单个感应电极122和单个驱动电极124的尺寸可以比触控电极111的单个感应电极112和单个驱动电极114的尺寸增加30％以上。电极面积增大以后，距离传感电极121所检测到的电容信号变化量增大，可以有效的检测出人体与显示装置的距离变化。具体的，当人体靠近传感检测区域120时，人体电场与距离传感电极121会形成一个耦合电容，距离传感电极121可以通过该耦合电容的变化量感测人体与显示装置之间的距离，并将该距离信号转换成对应的电信号后传导给信号检测芯片，信号检测芯片通过信号比对即可识别出人体与显示装置的距离远近并指导显示装置进行相应的动作。在本实施例中，距离传感电极可能会在一定程度上影响光的透过率，所以距离传感电极的设置可以绕开光学器件的透光位置。
在一个实施例中，如图5所示，传感检测区域120内设置的传感电极为环境光传感电极125，该环境光传感电极125由透明的感光材料制成，该感光材料具体可以是铝掺杂的ITO(Indium Tin Oxide，铟锡氧化物)或其他金属掺杂氧化物。另外，环境光传感电极125的排布方式与触控电极111不同，如图5所示，环境光传感电极125一般包括设置在下层的一整块电极126以及设置在上层的交叉放置的梳齿状电极128，其中，设置于下层的整块电 极126做金属掺杂，并用于检测显示装置所在环境光的强度变化；设置于上层的梳齿状电极128可以不做金属掺杂，并用于将下层的整块电极126切割为不同的区域，以增加环境光传感电极125的检测精度，同时也可以起到传导信号的作用。进一步的，设置于上层的梳齿状电极128也可以为其他形状，只要能够起到切割整块电极126并传导信号的作用即可，图中的形状只作为一种示意，不作为一种限定。具体的，当显示装置所在的环境光线强度发生变化时，环境光传感电极125可以把感应到的光信号转换为对应的电信号后传导给信号检测芯片，信号检测芯片通过信号比对即可识别出显示装置所在环境的光强度变化并指导显示装置进行相应的动作。在本实施例中，环境光传感电极125可以设置为一套或多套，且其设置的位置需绕开光学器件的透光位置。
在一个实施例中，如图6所示，传感检测区域120内设置的传感电极为距离传感电极121和环境光传感电极125，其中，距离传感电极121和环境光传感电极125之间设置有第二固定电位线140，在本实施例中，第二固定电位线140的作用在于屏蔽距离传感电极121和环境光传感电极125之间的信号传递，其形状可以不是如图6中规则的直线，但第二固定电位线140须将两种电极完全的分隔开，以阻隔两种电极之间的信号干扰。
进一步的，上述距离传感电极121的排布方式与触控电极111的排布方式相同，同样包括了纵横交错的感应电极和驱动电极，但距离传感电极121的电极尺寸略大于触控电极111的尺寸且可以只排布一层电极。当人体靠近传感检测区域120时，人体电场与距离传感电极121会形成一个耦合电容，距离传感电极121可以通过该耦合电容的变化量感测人体与显示装置之间的 距离，并将该距离信号转换成对应的电信号后传导给信号检测芯片，信号检测芯片通过信号比对即可识别出人体与显示装置的距离远近并指导显示装置进行相应的动作。上述环境光传感电极125由透明的感光材料制成，该感光材料具体可以是铝掺杂的ITO或其他金属掺杂氧化物，环境光传感电极的排布方式与触控电极不同，其具体包括设置在下层的一整块电极以及设置在上层的交叉放置的梳齿状电极，其中，设置于下层的整块电极做金属掺杂，设置于上层的梳齿状电极不做金属掺杂。当显示装置所在的环境光线强度发生变化时，环境光传感电极可以把感应到的光信号转换为对应的电信号后传导给信号检测芯片，信号检测芯片通过信号比对即可识别出显示装置所在环境的光强度变化并指导显示装置进行相应的动作。
在至少一个实施例中，如图7和图8所示，还提供了一种触控显示面板200，该触控显示面板200包括显示面板210、触控基板220以及通过触控基板绑定区设置于触控显示面板200上的信号检测芯片230。其中，触控基板220设置于显示面板210上，触控基板220包括触控检测区域和传感检测区域。如图7和图8所示，图中内边框的实线表示触控基板220的形状，图中内边框中的虚线表示触控检测区域和传感检测区域的边界线。为了方便理解，图7和图8中所示的触控基板220的面积是小于显示面板210的，但在实际应用中，触控基板220的尺寸可以与显示面板210的尺寸是同样大的，也可以比显示面板210的尺寸略小一些，图中的形状只作为一种示意，不作为一种限定。具体的，触控检测区域内设置有触控电极，触控电极通过信号线与信号检测芯片230电连接，信号检测芯片230通过纵横交错的触控电极形成的电容的容量变化确定被触摸的位置并计算出具体坐标，以此识别触控信号； 传感检测区域内设置有传感电极，传感电极同样通过信号线与信号检测芯片230电连接，信号检测芯片230通过读取传感电极转换的电信号确定环境信号的类别和强弱，并指导显示装置进行相应的动作，例如指导显示装置自动调整显示面板的显示亮度或自动调整麦克风音量等等。
在至少一个实施例中，如图7和图8所示，显示面板210包括显示区域211和非显示区域212。在这些实施例中，触控基板220的触控检测区域110设置于显示区域211上，触控基板220的传感检测区域120设置于非显示区域212上。通过这样的设置，可以使显示面板的显示区域211具备触控功能，而非显示区域212的空间也可被充分利用，减少了放置元器件的预留位置，从而实现了触控显示面板200的窄边框设计。
在一个实施例中，图8所示，非显示区域212可以包括设置于显示区域四周的边框区2121以及设置于显示区域一侧的凹槽区2122，传感检测区域120可以设置于边框区2121或凹槽区2122上。具体的，如图7所示，当显示面板的非显示区域212只包括边框区2121时，传感检测区域120可以设置在边框区2121上，优选的，传感检测区域120可以设置在上边框区2121上并避开上边框上的光学元器件；如图8所示，当显示面板的非显示区域212既包括边框区2121又包括凹槽区2122时，传感检测区域120可以设置在边框区2121和/或凹槽区2122上。优选的，传感检测区域120可以设置在凹槽区2122上并避开凹槽区2122上的光学元器件的位置。通过这样的设置，可以将距离检测和环境光检测的功能集成在触控显示面板200上，使整个显示装置更加智能化。
在至少一个实施例中，传感检测区域120设置在非显示区域212的边框 区或凹槽区，或者边框区和凹槽区的边界位置上，且设置了传感检测区域的非显示区相比于非显示区未设置传感检测区域的其他部分或显示区域来说，其透光率是相对比较高的，这样可以便于传感电极更为准确的检测到周围环境的变化。在本实施例中，凹槽区是将显示面板的TFT阵列和各层氧化膜进行刻蚀得到的，在凹槽区内不设置像素单元，另外，凹槽区对应的衬底基板和封装基板均无需进行切割，因而凹槽区制作难度低且透光率好。
在一个实施例中，显示面板210可以为玻璃显示面板或柔性显示面板，当显示面板210为玻璃显示面板时，触控基板220贴付于显示面板210的封装玻璃上，与显示面板210共同构成硬性的触控显示面板220；当显示面板210为柔性显示面板时，触控基板220贴付于显示面板210的柔性封装层上，与显示面板210共同构成柔性的触控显示面板200。另外，触控基板220也可直接用作显示面板210的封装盖板，其构成的触控显示面板200既可以是硬性也可以是柔性的。
上述显示面板200，通过将触控基板220的触控检测区域110设置于显示区域211上，传感检测区域设置于非显示区域212上，实现了在显示面板210上集成传感检测元件的效果。减少了显示面板的开槽空间或边框区间，使显示面板210易于实现窄边框设计；同时使触控显示面板200的功能更加智能化，集成度更高，是未来触控显示面板200的发展趋势。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详 细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
