由于PMOLED(Passive matrix organic light-emitting diode，被动矩阵式有机发光二极体)单纯地以阴极、阳极构成矩阵状，以扫描方式点亮阵列中的像素，每个像素都是操作在短脉冲模式下，为瞬间高亮度发光，具有结构简单，可以有效降低制造成本等优点，因此透明显示可以采用高透明度的PMOLED显示屏，而为保证显示效果其他区域仍然为AMOLED(Active-matrix organic light-emitting diode，主动矩阵式有机发光二极体)显示屏。若PMOLED的引出线仍从PMOLED的侧边引出，会增加PMOLED的侧边宽度或增加PMOLED和AMOLED之间的结合界面宽度，进而影响显示效果。
针对槽区的PMOLED的引出线从PMOLED的侧边引出，会增加PMOLED的侧边宽度或增加PMOLED和AMOLED之间的结合界面宽度进而影响显示效果的问题，提供一种能够提高显示效果的显示屏及显示终端。

具体地，可参见图3～4，图3为一实施例中的第一显示面板110的剖视图，图4为一实施例中的第一显示面板的俯视图。第一显示面板110包括第一基板111；第一电极层(即多个第一电极112所在的层)，形成于第一基板11上；第一像素限定层(未图示)，形成于第一电极层上；第二电极层(即多个第二电极114所在的层)，形成于第一像素限定层上；以及多个电极引出线116。
AMOLED具有TFT(Thin Film Transistor)阵列基板，采用独立的薄膜电晶体去控制每个像素，每个像素皆可以连续且独立的驱动发光，可以使用低温多晶硅或者氧化物TFT驱动，优点是驱动电压低，发光组件寿命长。
具体地，第二显示面板120包括第二基板及在第二基板上依次形成的TFT阵列(图未示)、第二像素限定层(图未示)、阳极(图未示)、发光结构(图未示)及阴极，以形成AMOLED显示面板。需要说明的是，第二显示面板120的阳极与TFT阵列的薄膜晶体管、发光结构一一对应设置，第二显示面板120的阴极可为面电极。其中，第二像素限定层为不透光材料，以确保第二显示面板120的数据线不可见，提高显示屏的视觉效果。
需要说明的是，AMOLED显示面板的阳极一般是图案化的，对应每个子像素形成；而AMOLED显示面板的阴极一般是整个面电极，覆盖在设有多个子像素的整个TFT阵列基板上。TFT阵列基板可以包括基板、缓冲层及薄膜晶体管等结构。
正如背景技术及前述介绍，与AMOLED显示面板不同的是，PMOLED显示面板的阳极和阴极一般为条状，即第一显示区AA1的第一显示面板110包括交叉的多条阳极条和多条阴极条，在阳极条和阴极条交叠的位置则形成一个子像素。因此PMOLED显示面板三面与AMOLED显示面板相接，PMOLED显示面板的阳极条和阴极条中必然有一电极线需从与AMOLED显示面板连接的边缘引出，这必然导致PMOLED的侧边宽度或增加PMOLED和AMOLED之间的结合界面宽度。
因此本申请提出一种增加电极引出线的方法，将该需从与AMOLED显示面板连接的边缘引出的电极线从PMOLED显示面板的不与AMOLED显示面板连接的边缘引出。
进一步地，考虑到阴极位于上方，无需引出，且阳极条位于阴极条的下方(本申请的下方是指靠近基板的方向，上方是指远离基板的方向，下同)，且阳极条的下方具有较多的功能膜层，例如钝化层、信号屏蔽层等等，这些功能膜层给引线的设置提供了优势。
继续参阅图3，在本实施例中，仅仅给出了涉及的结构层，而省略了或者简化了其他图层。该第一显示面板110包括第一基板111；第一电极层(即多个第一电极112所在的层)，形成于第一基板111上，第一电极层包括多个第一电极112。第一像素限定层(未示出)，形成于第一电极层上；第二电极层(即多个第二电极114所在的层)，形成于第一像素限定层上，第二电极层包括多个第二电极114；以及多个电极引出线116，用于引出多个第一电极112，多个电极引出线116分别与多个第一电极112连接，且多个电极引出线116分别与多个第二电极114沿相同的方向并行延伸。
继续参阅图1、3和4，第一电极112的至少一端与第二显示面板120相邻。多个第二电极114与多个第一电极112交叉设置。
第一显示面板110还包括用于引出多个第一电极112的多个电极引出线116，各个电极引出线116与各个第一电极112连接，且各个电极引出线116分别与各个第二电极114沿相同的方向并行延伸。上述显示屏100，具有均用于进行显示画面的第一显示区AA1和第二显示区AA2，可以真正实现全面屏显示。如此各个电极引出线116和各个第二电极114沿相同的方向并行延伸，进而可从第一显示面板110的同侧边缘引出。如此相比于传统第一电极112和第二电极114从各自的边缘引出的方案，至少可减少第一显示面板110一侧边的边框宽度，避免了增加第一显示面板的侧边宽度的问题，进而增大了显示区域的面积及提高了显示屏的显示效果。
例如图1所示的示例中，第一显示面板110为PMOLED显示面板，第二显示面板120为AMOLED显示面板时，电极引出线116从PMOLED显示面板的不与AMOLED显示面 板连接的边缘引出。可理解，第一基板和第二基板可为同一个基板。
如图4所示，多个第一电极112沿相同的方向并行延伸，且相邻的两个第一电极112间具有间距。多个第二电极114沿相同的方向并行延伸，且相邻的两个第二电极114间具有间距。并且多个电极引出线116沿相同的方向并行延伸，且相邻的两个电极引出线116间具有间距。
图5为一实施例中的第一显示面板的第二电极的示意图。在一实施例中，第一电极112、第二电极114及电极引出线116中的一个或多个的侧边设置为多个相接的弧形。具体地，在多个相接的弧形走线的延伸方向上，多个相接的弧形走线的宽度持续变化或者间断变化，且该间距连续变化或间断变化。宽度连续变化是指在多个相接的弧形走线上任意两个相邻位置处的宽度不相同。宽度间断变化是指在多个相接的弧形走线上存在部分区域内相邻两个位置的宽度相同，而在部分区域内相邻两个位置的宽度不相同。
通过将第一显示面板110中的第一电极112、第二电极114及电极引出线116中的一个或多个的侧边设置为多个相接的弧形走线，从而使得外部光线经过信号走线时，在多个相接的弧形走线的不同位置处产生的衍射条纹的位置不同。不同位置处的衍射条纹相互抵消，从而可以有效减弱衍射效应，进而确保摄像头设置在第一显示面板110下方时，拍摄得到的图形具有较高的清晰度。在一实施例中，第一电极层可以为阳极层。
继续参照图3，其中，电极引出线116设置在第一基板111上。在一实施例中，信号屏蔽层113设置在电极引出线116上且覆盖电极引出线116。第一电极层形成于信号屏蔽层113上。第一像素限定层则形成在第一电极层上。具体地，电极引出线116设置在第一像素限定层的下方，且避开摄像头等感光器件所在的区域。通过将电极引出线116设置在第一像素限定层下方且避开摄像头所在区域，可以避免电极引出线116对发光区域以及摄像头正常工作的干扰。并且，通过在电极引出线116和第一电极层之间形成信号屏蔽层113，可以确保电极引出线116不会对第一电极层产生信号干扰。
在一实施例中，电极引出线116位于第一电极层和第一基板111之间。也即，电极引出线116先于第一电极层进行制备得到。并且，电极引出线116设置在第一电极层下方，从而可以减小对第一电极层的工作影响。此时，第一电极层为阳极层。在另一实施例中，电极引出线116也可以设置于第一电极层上方，且位于第一像素限定层下方。
具体地，信号屏蔽层113设置于电极引出线116和第一电极112之间时，信号屏蔽层113覆设于电极引出线116上，信号屏蔽层113设有开孔，在信号屏蔽层113上形成第一电极112，并且在开孔内形成第一电极112的材料，以使第一电极112和电极引出线116 连接。
当电极引出线116设置在第一电极层上方时，此时第一电极层为阴极层，从而避免电极引出线116对其正常的工作产生干扰。
在一实施例中，第一基板111包括玻璃基板和形成在玻璃基板上方的柔性基板。通过增设柔性基板，可以确保第一基板具有一定的弯折性能。
在一实施例中，第一像素限定层包括与第一子显示区AA12对应的阻光第一像素限定层，阻光第一像素限定层可以为不透光材料(如阻光或者吸光材料，比如黑色的有机胶等)。由于第一子显示区AA12并不需要设置摄像头，因此对该区域的透光率要求较低。且第一像素限定层还包括与第二子显示区AA14对应的透光第一像素限定层，透光第一像素限定层为透光材料。此时，电极引出线116为金属或者透明金属氧化物材料。例如，当电极引出线116采用透明金属氧化物时，可以采用氧化铟锡(ITO)、氧化铟锌(IZO)、掺杂银的氧化铟锡(Ag+ITO)或者掺杂银的氧化铟锌(Ag+IZO)等。通过将第一子显示区AA12的阻光第一像素限定层设置为不透光，以牺牲一定的面板透光率来确保经过第一子显示区AA12的电极引出线116不可见，提高显示屏的显示效果。
图6为一实施例中的第一显示面板110的第一像素限定层中的像素开口123的结构示意图。在一实施例中，第一像素限定层中形成有像素开口123。第一像素限定层的每个像素开口123对应一个发光结构。各像素开口123的形状为圆形、椭圆形、哑铃形或者葫芦形其中一种，具体如图6所示，像素开口123的形状为哑铃形。通过将各子像素设置为圆形、椭圆形、哑铃形或者葫芦形其中一种，从而使得外部光线经过发光结构时，在子像素的不同位置处产生的衍射条纹的位置不同。不同位置处的衍射条纹相互抵消，从而可以有效减弱衍射效应，进而确保摄像头设置在第一显示面板110下方时，拍摄得到的图形具有较高的清晰度。并且，圆形、椭圆形、哑铃形或者葫芦形可在最大限度上扩大各个子像素的面积，进一步提高透光率。
本申请设置电极引出线116的方案可应用于纯粹的PMOLED显示面板，也可用于PMOLED显示面板与AMOLED显示面板的复合屏。该显示屏100为PMOLED显示面板与AMOLED显示面板的复合屏，即第一显示区AA1的第一显示面板110为PMOLED显示面板，第二显示区AA2的第二显示面板120为AMOLED显示面板。具体在附图1所示的显示屏100中，其同时具有AMOLED显示面板和PMOLED显示面板，即为两者的复合屏。由于PMOLED显示面板无TFT驱动阵列，使得光线透过率高。因此可在PMOLED显示面板下方设置感光器件。当感光器件工作时，感光器件可以从第一显示区AA1处获 得光线；当感光器件不工作时，第一显示区AA1可以正常显示画面。从而提高手机的显示效果。
进一步地，当AMOLED显示面板和PMOLED显示面板两者复合时，PMOLED显示面板的部分边缘与AMOLED显示面板相接，即PMOLED显示面板还具有不与AMOLED显示面板相接的边缘。
具体在图1所示的显示屏100中，第一显示区AA1处于第二显示区AA2的顶部，且第一显示区AA1的顶端与第二显示区AA2的顶端平齐。这样设置之后，第一显示区AA1位于整个显示屏100的边缘，能够减少对显示画面效果的影响。相应地，电极引出线116从第一显示区AA1的顶端引出。
请继续参照图3，信号屏蔽层113与第二显示面板120的钝化层、层间绝缘层或平坦化层在同一工艺步骤中形成。如此可在AMOLED显示面板形成钝化层、层间绝缘层或平坦化层时同层、同材、同步形成该信号屏蔽层113，进而可不增加工序，同时也不会增加膜层的厚度和结构。
进一步地，电极引出线116与第二显示面板120的源漏极层或栅极层在同一工艺步骤中形成，且阻光第一像素限定层为不透光材料。也就是说，电极引出线116可与AMOLED显示面板内的源漏极层或栅极层同层、同材、同步形成，不透光材料的阻光第一像素限定层可使电极引出线116不可见，如此不仅可节省工序，还可避免增加膜层导致的膜层厚度增加。
在一实施例中，第一显示区AA1的第一像素限定层均为透光材料。此时，电极引出线116为透明金属氧化物材料。通过将第一显示区AA1的第一像素限定层设置为透光材料，可以确保显示屏具有较好的透光率，确保设置于下方的摄像头等感光器件的正常工作。通过将电极引出线116设置为透明的金属氧化物时，可以确在保在第二显示面板120为透明显示面板时，其不会对显示面板的透明度产生影响。
请继续参照图4，进一步地，电极引出线116与第二电极114平行设置，也就是说电极引出线116的延伸方向与第二电极114的延伸方向相同。如此电极引出线116从第二电极114的引出边缘同侧引出。
进一步地，电极引出线116与第二电极114在第一基板111上的正投影相互错开。具体地，电极引出线116在第一基板111的正投影位于相邻两条第二电极114之间或位于最边缘的第二电极114的外侧。如此避开了第一电极112和第二电极114交叠的位置，即电极引出线116的设置避开了子像素，从而避免了电极引出线116的设置影响子像素进而导 致影响显示屏100的问题。
值得说明的是，因为电极引出线116与第一电极112的连接处设置了开孔，因此将导致该处第一电极112稍稍下沉，因此此处不利于形成子像素。可选地，电极引出线116在第一基板111的正投影位于相邻两条第二电极114之间。此外还可尽可能地不增加PMOLED显示面板沿第一电极112的延伸方向的宽度。可理解，电极引出线116尽可能地均匀分布于相邻两条第二电极114之间的区域或位于最边缘的第二电极114的外侧的区域，以保证电极引出线116的设置不影响其他膜层。
可理解，在一些实施例中，相邻两条第二电极114之间可设有两条以上的电极引出线116。可理解，各条电极引出线116的长度可设置不相同，也可将部分电极引出线116的长度设置为相同。可选地，各条电极引出线116的长度尽量不相同设置。可选地，各条电极引出线116的一端对齐设置，另一端用于与第一电极112连接。
图7～8为不同实施例中的各个子显示面板的俯视图，示出了第一显示面板110的各个子显示面板1012的第一电极112、第二电极114及电极引出线116的俯视分布情况。本申请的第一显示区AA1具有多个显示分区AA11，各显示分区AA11都设置有子显示面板1012，子显示面板1012均包括上述第一基板111、第一电极层、第一像素限定层及第二电极层。第一电极层包括多个第一电极112，第一电极112的至少一端与第二显示面板120相邻。各个子显示面板1012均独立驱动。
具体地，各子显示面板1012的第一电极层和第二电极层均相互独立，也就是说，不同子显示面板1012内的第一电极层和第二电极层可分别独立写入信号，还可同步写入信号。如此通过将第一显示区AA1设置成两个及两个以上的显示分区AA11，并分别设置子显示面板1012，扫描时对各子显示面板1012按照图7所示的扫描方向103开进行扫描，从而可大幅度降低扫描的行数，进而通过提高每行的扫描时间来提高每行的发光时间，以在不降低分辨率的前提下，实现提升第一显示区AA1的亮度的目的。
进一步地，第一显示面板110为PMOLED显示面板时，第二电极层包括多个第二电极114。多个第二电极114和多个第一电极112交叉形成一个子显示面板1012。
进一步地，至少一个子显示面板1012内设置有多个电极引出线116，同一显示分区内的各个电极引出线116与各个第二电极114沿相同的方向并行延伸。至少一个子显示面板1012的各个第一电极112均设置有电极引出线116。
请继续参照图7～8，同一子显示面板1012内，电极引出线116和第二电极114从PMOLED显示面板的同侧边缘引出。如此相比于传统第一电极112和第二电极114从各 自的边缘引出的方案，至少可减少PMOLED显示面板一侧边的边框宽度，避免了增加PMOLED的侧边宽度的问题，进而增大显示区域的面积及提高显示屏的显示效果。
针对PMOLED显示面板的部分边缘与AMOLED显示面板连接的情况，此时第一电极112采用传统的走线需从PMOLED显示面板的与AMOLED显示面板连接的边缘引出，因此不可避免地增加PMOLED显示面板与AMOLED显示面板之间的结合界面宽度。针对该技术问题，将该电极引出线116具体应用到具体在PMOLED显示面板与AMOLED显示面板复合中的PMOLED显示面板时，将同一子显示面板1012内的电极引出线116和第二电极114自PMOLED显示面板引出的同侧边缘不与AMOLED显示面板连接。
如此还可减少PMOLED显示面板与AMOLED显示面板之间的结合界面宽度，避免了电极引出线116需从PMOLED显示面板的与AMOLED显示面板连接的侧边引出导致PMOLED和AMOLEDD之间的结合界面宽度增加导致影响显示效果的问题，或避免了第一电极112引出需穿过AMOLED的显示区进而影响AMOLED的显示效果的问题，进而增大了显示区域的面积及提高了显示屏的显示效果。
请继续参照图7，例如，将PMOLED显示面板对应的第一显示区AA1分成2个显示分区AA11，分别设置子显示面板1012，然后对2个子显示面板1012按照扫描方向103分别进行扫描，和原来整屏扫描相比，扫描行数降低一半，亮度就可以提升一倍。为了配合分区扫描，两个子显示面板1012的数据线分开输入，但数据信号同步写入；所以输入的数据线数量会增加一倍。
请继续参照图8，同理若将PMOLED显示面板对应的第一显示区AA1分成3个显示分区AA11，分别设置子显示面板1012，然后对3个子显示面板1012分别进行扫描，和原来整屏扫描相比，亮度就可以提升到3倍；同时数据线也必须分成3个子显示面板1012中的数据线，3个子显示面板1012的数据信号同步写入，所以输入的数据线数量会变成3倍。
当显示分区AA11为三个或三个以上时，各显示分区AA11的子显示面板1012以第二电极114相互平行且间隔设置的方式依次连接，至少位于相邻两个显示分区AA11之间的显示分区AA11内的子显示面板1012设置有多个电极引出线116。
请继续参照图8，在一些实施例中，当显示分区AA11为三个或三个以上时，各显示分区AA11的子显示面板1012依次连接，且各子显示面板1012的各第二电极114相互平行且间隔设置，至少位于相邻两个显示分区AA11之间的显示分区AA11内子显示面板1012的各第一电极112的下方分别设置有前述电极引出线116。如此设置，使得电极引出 线116从该子显示面板1012不与其他子显示面板1012连接的边缘引出，即各子显示面板1012内的电极引出线116均从显示屏100的垂直于第二电极114的同侧边缘引出。如此解决了位于中间的子显示面板1012内的第一电极112引出需穿过两侧的子显示面板1012进而影响AMOLED的显示效果的问题，同时也减少了显示分区AA11之间的结合界面宽度。
可理解，在一实施例中，各子显示面板1012内的每条第一电极112的下方均设置电极引出线116，各电极引出线116自所在子显示面板1012未与其他子显示面板1012连接的边缘引出，从而可减小相邻两个显示分区AA11之间的结合界面宽度。
进一步地，各子显示面板1012内的各电极引出线116均从对应的子显示面板1012的同侧边缘引出；即各子显示面板1012内的电极引出线116均从显示屏100的同侧边缘引出。如此在减小相邻两个显示分区AA11之间的结合界面宽度的同时，也可减少显示屏100其他各边缘的宽度，只需留一侧边缘用于电极引出线116和第二电极114引出即可，从而有利于显示屏100实现窄边框化。
可理解，在另一具体示例中，多个子显示面板1012依次连接，且多个子显示面板1012的各第一电极112相互平行且间隔设置(图未示)。此时，各子显示面板1012内的电极引出线116可选均从显示屏100的垂直于第一电极112的同侧边缘引出。只是这种情况相比上述情况，没有足够的位置设置电极引出线116。
在一些实施例中，第一显示面板110为类AMOLED显示面板，第二显示面板120为AMOLED显示面板。类AMOLED显示面板是指其像素电路仅包含一个开关器件(即驱动TFT)，而无电容结构。类AMOLED显示面板的其他结构与AMOLED显示面板相同。下面以第一显示面板110为类AMOLED显示面板为例进行说明。
图9为另一实施例中的第一显示面板的结构示意图，其中的第一显示面板为类AMOLED显示面板。该类AMOLED显示面板包括第一基板810以及设置于第一基板810上的多个像素电路820(也即TFT阵列)。像素电路820上设置有第一电极层。第一电极层包括多个第一电极830。第一电极830与像素电路820一一对应。此处的第一电极830为阳极。类AMOLED显示面板还包括像素限定层840，设置于第一电极830上。像素限定层840具有多个像素开口870，像素开口870内设置有发光结构850，以形成子像素(未图示)，子像素与第一电极830一一对应。发光结构850的上方设置有第二电极860，第二电极860为阴极，该阴极为面电极，也就是由整面的电极材料形成的整面电极。像素电路820中设置有扫描线、数据线和TFT开关器件。扫描线和数据线均与TFT开关器件连 接。扫描线控制TFT开关器件的开启和关闭，数据线在像素开启时，为第一电极830提供驱动电流，以控制子像素发光。
在一实施例中，第一基板810可以为刚性基板，如玻璃基板、石英基板或者塑料基板等透明基板；基板810也可为柔性基板，如PI薄膜等，以提高器件的透明度。发光结构850可以是OLED(Organic Light-Emitting Diode，有机发光二极管)。
图10为一实施例中的像素电路820的电路原理的示意图。与传统的AMOLED显示面板的像素电路不同，像素电路820仅包括开关器件，而不包括存储电容等元件，从而形成无电容结构。在本实施例中，像素电路820包括一个开关器件。开关器件与第一电极830一一对应设置，即一个子像素对应一个开关器件。开关器件包括第一端2a、第二端2b和控制端2c，详见后续具体介绍。扫描线与开关器件的控制端2c连接，数据线连接开关器件的第一端2a，第一电极830连接开关器件的第二端2b。如图8所示。上述像素电路820中，通过数据线连接开关器件的第一端2a，扫描线连接开关器件的控制端2c，能够将像素电路820中的开关器件减少至一个，大大降低扫描线的负载电流以及数据线的负载电流。
上述显示面板中扫描线控制像素电路820的开启和关闭，仅需提供像素电路820中的开关器件所需的开关电压，不需要输入发光结构(OLED)的电流，大大降低扫描线的负载电流，使得扫描线可以采用ITO等透明材料制作。并且，数据线在像素电路820开启时，为阳极提供驱动电流，控制子像素发光，数据线在每一时刻只需供应一个子像素的驱动电流，数据线的负载也很小。因此，数据线也可以采用ITO等透明材料，从而提高了显示屏的透光率。多个子像素共用面电极(阴极)，每一时刻一行子像素的电流由整面阴极提供，对阴极的导电性要求大幅度降低，可以采用高透明电极，提高了透明度，提高了屏幕整体的一致性，并且不需要负性光刻胶分开阴极。
在一实施例中，第一电极830可以为设置为圆形、椭圆形、哑铃形或者葫芦形其中一种，具体可以参考图6。通过将第一电极830设置为圆形、椭圆形、哑铃形或者葫芦形其中一种，同样可以弱化衍射效应。在一实施例中，像素限定层840中的像素开口的形状为圆形、椭圆形、哑铃形或者葫芦形其中一种，如图6，从而同样可以弱化衍射效应。在一实施例中，扫描线和数据线等信号线可以多个相接的弧形走线，从而达到改善衍射的效果。
图11为一实施例中的显示终端的示意图。本申请一实施例还提供一种显示终端，该显示终端包括设备本体910和显示屏920。显示屏920设置在设备本体910上，且与该设备本体910相互连接。其中，显示屏920可以采用前述任一实施例中的显示屏，用以显示 画面。
图12为一实施例中的设备本体910的示意图。在本实施例中，设备本体910上可设有开槽区912和非开槽区914。在开槽区912中可设置有诸如摄像头930以及光传感器等感光器件。此时，显示屏920的第一显示区AA1对应于开槽区912贴合在一起，以使得上述的诸如摄像头930及光传感器等感光器件能够透过该第一显示区AA1对外部光线进行采集等操作。
在一实施例中，为了提高透光率，在第一显示区AA1可以不设置偏光片，也即第一显示面板110中不设置偏光片。并且由于第一显示区AA1中的第一显示面板110能够有效改善外部光线透射该第一显示区AA1所产生的衍射现象，从而可有效提升显示终端上摄像头930所拍摄图像的质量，避免因衍射而导致所拍摄的图像失真，同时也能提升光传感器感测外部光线的精准度和敏感度。
上述显示终端可以为手机、平板电脑、掌上电脑、ipod等数码设备。
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申请专利范围的限制。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。
