为使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施方式作进一步地详细描述。
图1和图2是本申请实施例提供的一种显示装置的部分结构示意图。图3是本申请实施例提供的一种包括在第一状态下的柔性显示面板的显示装置的平面结构示意图,图4是本申请实施例提供的一种包括在第二状态下的柔性显示面板的显示装置的平面结构示意图。结合图1至图4,显示装置包括柔性显示面板1和支撑件2,支撑件2用于支撑柔性显示面板1在第一状态和第二状态中切换,柔性显示面板1的显示面在第一状态下为平面,显示面在第二状态下为曲面。支撑件2包括固定部21、支撑单元22和伸缩连杆23,固定部21与柔性显示面板1的一端固定连接,固定部21与支撑单元22的一端相连,支撑单元22与柔性显示面板1滑动连接。伸缩连杆23与支撑单元22相连,伸缩连杆23的延伸方向与第一平面a相交,第一平面a为柔性显示面板1的显示面在第一状态下所在的平面。需要说明的是,图1和图2中仅示出了柔性显示面板1和支撑件2中的固定部21和支撑单元22,未示出伸缩连杆23的结构。
由于伸缩连杆23的延伸方向与第一平面a相交,且伸缩连杆与支撑单元22相连,因此伸缩连杆伸缩时,可以使得支撑单元22的形状发生变化;由于固定部21与支撑单元22的一端相连,且固定部21与柔性显示面板1的一端固定连接,因此支撑单元22的形状发生变化可以带动固定部21的位置发生变化,进而带动与固定部21相连的柔性显示面板1的一端的位置发生变化,使得柔性显示面板1的显示面在平面和曲面之间进行切换。在支撑件支撑柔性显示面板在第一状态和第二状态中切换时,由于柔性显示面板1与支撑单元22滑动连接,因此若柔性显示面板1在第一状态和第二状态的切换过程中局部区域收到挤压或拉伸产生应力,这部分应力也能够及时释放,不会因为柔性显示面板与支撑单元固定连接而无法及时释放,利于延长柔性显示面板的使用寿命。
需要说明的是,固定部21与柔性显示面板1的一端在M处固定连接处为图3和图4所示实施例中的M标记处。示例性地,固定部21与柔性显示面板1的一端通过胶粘的方式固定连接。可选地,固定部21与柔性显示面板1的一端通过双面压敏胶(Pressure Sensitive Adhesives,PSA)或者超强黏性(Very High Bond,VHB)双面胶粘接固定。
示例性地,如图3和图4所示,显示装置还包括机壳3。机壳3遮挡了柔性显示面板1远离固定部21的一端,柔性显示面板的显示面未被遮挡的部分即为显示区域AA。
综上所述,本申请实施例提供的显示装置,包括柔性显示面板和支撑件,支撑件包括固定部、支撑单元和伸缩连杆。伸缩连杆的延伸方向与第一平面相交,伸缩连杆与支撑单元相连,支撑单元的一端与固定部相连,固定部与柔性显示面板的一端固定连接,因此伸缩连杆伸缩时,可以使得支撑单元的形状发生变化,并依次带动固定部、与固定部相连的柔性显示面板的一端的位置发生变化,使得柔性显示面板在第一状态和第二状态之间切换。由于柔性显示面板和支撑单元滑动连接,因此柔性显示面板在切换过程中产生的应力能够及时释放,利于延长柔性显示面板的使用寿命。
示例性地,如图3和图4所示,伸缩连杆23的一端与机壳3固定连接。将伸缩连杆23的一端固定在机壳上,便于通过电机驱动等方式,在驱动伸缩连杆23与支撑单元22相连的一端伸长或缩短的同时,可以调整伸缩连杆23与第一平面之间的夹角,以确定伸缩连杆23与支撑单元22相连的一端所在的位置。例如第一种条件下,电机驱动伸缩连杆23与第一平面形成第一夹角,并使得伸缩连杆23具有第一长度;在第二种条件下,电机驱动伸缩连杆23与第一平面形成第二夹角,并使得伸缩连杆23具有第二长度。这两种情况下伸缩连杆23与支撑单元22相连的一端所在的位置不同,显示面的弧度不同。如果将伸缩连杆的一端固定在一个可活动的结构,有可能导致第一种条件和第二种条件下伸缩连杆23与支撑单元22相连的一端所在的位置相同,进而导致这两种条件柔性显示面板1的显示面的弧度相同,干扰电机操作。
可选地,伸缩连杆23包括相连的套筒和柱体,柱体与支撑单元22相连,套筒与机壳3相连,柱体位于套筒内。套筒和柱体之间还可以通过螺纹连接等方式相连。
可选地,伸缩连杆23还可以是包括转动连接的第一连杆和第二连杆,第二连杆与支撑单元22相连,第一连杆与机壳3相连,在电机的驱动下,第一连杆和第二连杆之间可以形成不同的角度,从而使得伸缩连杆23可以伸缩,并调整经过伸缩连杆23与机壳的连接处和伸缩连杆23与支撑单元22的连接处的连线与第一平面之间的角度。
在一种可能的实施例中,如图1所示,支撑单元22具有滑槽220,柔性显示面板1包括背板11、盖板12以及位于背板11和盖板12之间的显示结构13,背板11的边缘位于滑槽220内。柔性显示面板1在第一状态和第二状态切换的过程中,将背板11的边缘设置在滑槽220内可以起到限位作用,防止柔性显示面板1滑出脱落。
在一种可能的实施例中,支撑单元22包括依次相连的多个轨道块221,伸缩连杆23与多个轨道块221中的一个相连。通过在支撑单元22中设置多个轨道块221,可以使得支撑单元22的形状更易于变化。并且,伸缩连杆23与多个轨道块221中的一个相连的这种支撑单元的工艺较简单,即可以使用较简单的工艺实现柔性显示面板1在第一状态和第二状态中切换。在其他可能的实施例中,支撑单元22不包括多个轨道块221,而是包括长度方向与柔性显示面板1的长度方向x平行的支撑条,该支撑条具有长度方向与柔性显示面板1的长度方向x平行的滑槽,背板1的边缘位于滑槽内。
示例性地,如图1至图4所示,固定部21的长度方向与柔性显示面板1的长度方向x相交,支撑件2包括两个支撑单元22,支撑单元22的长度方向与柔性显示面板1的长度方向x相同,每个支撑单元22分别和固定部21的两端相连。通过设置分别和固定部21的两端相连的两个支撑单元22,从而便于支撑件具有相对的两个滑槽220,且可使得背板11相对的两个边缘分别位于两个滑槽220内,以使柔性显示面板1在第一状态和第二状态之间切换时更加稳定不会脱出。
图5是本申请实施例提供的另一种显示装置的平面结构示意图。如图5所示,支撑件2包括多个伸缩连杆23,多个伸缩连杆23的数量小于多个轨道块221的数量,每个伸缩连杆23分别与多个轨道块221相连。在其他可能的实施例中,多个伸缩连杆23的数量等于多个轨道块221的数量。通过设置多个伸缩连杆23,可以通过分别控制每个伸缩连杆23的伸缩程度和伸缩连杆与第一平面之间的角度,从而独立控制每个与伸缩连杆23相连的轨道块221的位置,从而更为精细的控制支撑单元22的形状。
在一种可能的实施例中,多个轨道块221包括依次相连的第一轨道块2211和至少一个第二轨道块2212,第一轨道块2211位于至少一个第二轨道块2212远离固定部21的一侧。
下面对第一轨道块和第二轨道块之间的连接方式进行说明。
示例性地,第一轨道块2211具有第一连接部,第二轨道块2212具有第二连接部。第一连接部和第二连接部中的一个为第一条形槽a,另一个为第一条形柱b,第一条形柱b位于第一条形槽a内,第一条形槽a的长度方向、第一条形柱b的长度方向和支撑单元22的长度方向均相同,即第一条形槽a的长度方向、第一条形柱b的长度方向和柔性显示面板1的长度方向x均相同。具有第一条形槽a的轨道块221还包括第一驱动结构c,第一驱动结构c与第一条形柱b相连,第一驱动结构c用于驱动第一条形柱b和第一条形槽a沿平行于柔性显示面板的长度方向x的方向相对运动。
例如图3和图4所示,多个轨道块221包括依次相连的第一轨道块2211和一个第二轨道块2212。第一轨道块2211的第一连接部为第一条形槽a,且第一轨道块2211还包括第一驱动结构c,第二轨道块2212的第二连接部为第一条形柱b。通过在第一轨道块2211和第二轨道块2212上设置第一条形槽a、第二条形柱b和第一驱动结构c,第一驱动结构c用于驱动第一条形柱b和第一条形槽a沿平行于柔性显示面板的长度方向x的方向相对运动,可以在柔性显示面板的长度方向x延长或缩短支撑单元22的长度,从而可以增大或缩小柔性显示面板1的显示面的显示区域AA的面积。配合伸缩连杆23的伸缩,可以使得柔性显示面板1的显示面在平面和曲面之间切换的同时,扩大或缩小显示区域AA。
在其他可能的实施例中,第一轨道块2211的第一连接部为第一条形柱b,第二轨道块2212的第二连接部为第一条形槽a,且第二轨道块2212还包括第一驱动结构c。
在其他可能的实施例中,也可以根据用户对柔性显示面板1的长度、或者对柔性显示面板1的显示面在伸缩连杆23的长度不变时即可形成的曲面的弧度等要求,设计更多个第二轨道块2212。每个第二轨道块2212可以均包括一个第一条形柱b和第二条形槽d,且第一条形柱b和第二条形槽d相匹配,以使得相邻的两个第二轨道块2212之间通过第一条形柱b和第二条形槽d相连。此外,具有第二条形槽d的第二轨道块2212还具有第二驱动结构f,第二驱动结构f用于驱动相邻两个第二轨道块2212沿平行于柔性显示面板的长度方向x的方向相对运动。
图6是本申请实施例是提供的另一种显示装置的平面结构示意图。与图4所示的实施例相比,图6中所示的实施例中,柔性显示面板1的显示面为曲面。在柔性显示面板的长度方向x上,图6所示实施例中显示区域AA的尺寸比图4所示实施例中显示区域AA的尺寸大,即图6所示实施例中显示区域AA的面积比图4所示的实施例中的显示区域AA的面积大。
示例性地,多个伸缩连杆23包括与第一轨道块2211相连的一个伸缩连杆。由于第一驱动结构2211位于第二驱动结构2212远离固定部21的一侧,且第一驱动结构2211和第二驱动结构2212之间的相对位置可以由第一驱动结构c控制,因此如图3、图4或图6所示,若支撑件2包括一个伸缩连杆23,则该伸缩连杆23与第一轨道块2211相连;或者,如图5所示,若支撑件2包括多个多个伸缩连杆23,则至少有一个伸缩连杆23和一个第一轨道块2211相连。以使得第一轨道块2211及位于第一轨道块2211远离固定部21的其他结构(例如除了第一轨道块2211和第二轨道块2212以外的其它轨道块221)的位置发生变化的动力由伸缩连杆23提供,而位于第一轨道块2211靠近固定部21一侧的第二轨道块2212的位置发生变化的动力由第一驱动结构c提供。
在一种可能的实施例中,第一条形槽a在第二平面的正投影为向远离柔性显示面板1的方向凸出的弧形,第一条形柱b在第二平面的正投影为向远离柔性显示面板1的方向凸出的弧形,第二平面为垂直于第一平面且与平行于柔性显示面板1的长度方向x的平面。将第一条形槽a和第一条形柱b的形状设置为弧形,可以在第一驱动结构c的驱动下,相连的第一轨道块2211和第二轨道块2212相对远离以增大显示区域AA的面积同时,可以使得位于第一轨道块2211和第二轨道块2212上方的显示面具有弯曲的弧度,从而使得即使伸缩连杆23不伸长或缩短,仅第一轨道块2211和第二轨道块2212之间相对远离,也可以实现让显示面由平面变为曲面、或者由曲面变为弯折程度更大的曲面的目的。
在另一种可能的实施例中,第一条形槽a的形状为直线形,第一条形柱b的形状为直线形。直线形的第一条形槽a和第一条形柱b配合,可以实现增大或缩小显示区域AA的面积的目的。
图7是本申请实施例提供的一种第一轨道块的立体结构示意图和在多个角度下的平面结构示意图。如图7所示,第一轨道块2211具有第一条形槽a和第一驱动结构c,第一驱动结构c的表面具有轮齿结构(图中未示)。图8是本申请实施例提供的一种第二轨道块的立体结构示意图和在多个角度下的平面结构示意图。如图8所示,第二轨道块2212具有第一条形柱b,第一条形柱a的表面具有与锯齿结构相匹配的轮条结构。第一驱动结构c通过旋转表面的轮齿结构,从而驱动相匹配的轮条结构,进而在柔性显示面板1的长度方向x上驱动第一条形柱b与第一条形槽a相对远离或靠近。示例性地,第一驱动结构为电机驱动结构。
下面对第二轨道块和固定部之间的连接方式进行说明。
在一种可能的实施例中,固定部21与第二轨道块2212相连,与固定部21相连的第二轨道块2212还具有第三连接部,固定部21具有第四连接部。第三连接部和第四连接部中的一个为第二条形槽d,另一个为第二条形柱e,第二条形柱e位于第二条形槽d内,第二条形槽d的长度方向、第二条形柱的长度方向和支撑单元的长度方向相同,即第二条形槽d的长度方向、第二条形柱e的长度方向和柔性显示面板1的长度方向x均相同。具有第二条形槽d的固定部21或者第二轨道块2212还包括第二驱动结构f,第二驱动结构f与第二条形柱d相连,第二驱动结构f用于驱动第二条形柱e沿平行于柔性显示面板的长度方向x的方向相对运动。
例如图3、图4和图6所示,固定部21的第四连接部为第二条形柱e,与固定部21相连的第二轨道块2212的第三连接部为第二条形槽d,且该第二轨道块2212还包括第二驱动结构f。通过在第二轨道块2212和固定部21上设置第二条形槽d、第二条形柱e和第二驱动结构f,第二驱动结构f用于驱动第二条形柱e和第二条形槽d沿平行于柔性显示面板的长度方向x的方向相对运动,可以在柔性显示面板的长度方向x延长或缩短支撑单元22的长度,从而可以增大或缩小柔性显示面板1的显示面的显示区域AA的面积。配合伸缩连杆23的伸缩,可以使得柔性显示面板1的显示面在平面和曲面之间切换的同时,扩大或缩小显示区域AA。
在其他可能的实施例中,与固定部21相连的第二轨道块2212的第三连接部为第二条形柱e,固定部21的第四连接部为第二条形槽d,且固定部21还包括第二驱动结构f。
在一种可能的实施例中,第二条形槽d在第二平面的正投影为向远离柔性显示面板1的方向凸出的弧形,第二条形柱e在第二平面的正投影为向远离柔性显示面板1的方向凸出的弧形。将第二条形槽d和第二条形柱e的形状设置为弧形,可以在第二驱动结构f的驱动下,相连的固定部21和第二轨道块2212相对远离以增大显示区域AA的面积同时,可以使得位于与固定部21相连的第二轨道块2212上方的显示面具有弯曲的弧度,从而使得即使伸缩连杆23不伸长或缩短,仅固定部21和第二轨道块2212之间相对远离,也可以实现让显示面由平面变为曲面、或者由曲面变为弯折程度更大的曲面的目的。
在另一种可能的实施例中,第二条形槽d的形状为直线形,第二条形柱e的形状为直线形。直线形的第二条形槽d和第二条形柱e配合,可以实现增大显示区域AA的面积的目的。
如图8所示,与固定部21相连的第二轨道块2212还具有第二条形槽d和第二驱动结构f,第二驱动结构f的表面具有轮齿结构(图中未示)。图9是本申请实施例提供的一种固定部的立体结构示意图和在多个角度下的平面结构示意图。如图9所示,固定部21具有第二条形柱e,第二条形柱e的表面具有与锯齿结构相匹配的轮条结构。第二驱动结构f通过旋转表面的轮齿结构,从而驱动相匹配的轮条结构,进而在柔性显示面板1的长度方向x上驱动第二条形柱e与第二条形槽d相对远离或靠近。示例性地,第二驱动结构为电机驱动结构。
下面对支撑单元22中位于第一轨道块2211远离固定部21一侧的其他结构进行说明。
在一种可能的实施例中,如图3和图4所示,多个轨道块221还包括依次转动连接的多个第三轨道块2213,多个第三轨道块2213位于第一轨道块2211远离固定部32的一侧,且多个第三轨道块2213中的一个与第一轨道块2211转动连接。通过设置多个第三轨道块2213,以使得在伸缩连杆23驱动第一轨道块2211运动时,多个第三轨道块2213靠近柔性显示面板1的一侧可以在第一轨道块2211的带动下自然地形成弧度或恢复平面,从而使得位于多个第三轨道块2213上方的显示面在平面和曲面之间切换。
图10是本申请实施例提供的一种第三轨道块的立体结构示意图和在多个角度下的平面结构示意图。结合图2和图10,相邻两个第三轨道块2213之间通过孔轴结构连接。例如对于相邻的两个第三轨道块2213,远离第一轨道块2211的第三轨道块2213具有连接轴h,靠近第一轨道块2211的第三轨道块2213具有连接孔g,连接轴h与连接孔g相匹配且连接轴位于连接孔g内。可选地,也可以是对于相邻的两个第三轨道块2213,远离第一轨道块2211的第三轨道块2213具有连接孔g,靠近第一轨道块2211的第三轨道块2213具有连接轴h。
示例性地,在平行于第一平面且垂直于柔性显示面板1的长度方向x的方向上,连接轴h的尺寸小于第三轨道块2213的尺寸,以避免对柔性显示面板1造成损伤。
示例性地,第一轨道块2211和与第一轨道块2211相连的第三轨道块2213之间也通过孔轴结构连接。如图2、图7和图10所示,第一轨道块2211具有连接孔g,与第一轨道块2211相连的第三轨道块2213具有连接轴h。
在图1至图10所示实施例中,支撑单元22仅包括3个第三轨道块2213,在其他可能的实施例中,也可以根据用户对对柔性显示面板1的长度等要求,设计更多个第二轨道块2212。图11是本申请实施例提供的另一种包括在第一状态下的柔性显示面板的显示装置的平面结构示意图,图12是本申请实施例提供的另一种包括在第二状态下的柔性显示面板的显示装置的平面结构示意图。如图11和图12所示,支撑单元22也可以包括6个第三轨道块2213。
在图1至图12所示实施例中,支撑单元22还包括承载部222,承载部222与距离固定部21最远的一个第三轨道块2213相连。在平行于柔性显示面板1的长度方向x的方向上,承载部222的尺寸比轨道块221的尺寸大,且承载部222的尺寸会影响柔性显示面板1的显示面中可以不形成曲面的区域的面积大小。可选地,第四轨道块222与第三轨道块2213通过孔轴结构相连。
下面对滑槽220的位置进行示例性说明。
在一种可能的实施例中,结合图2和图7,滑槽220在第二平面的正投影与第一轨道块2211的连接孔g在第二平面的正投影至少部分重合;结合图2和图10,滑槽220在第二平面的正投影与第三轨道块2213的连接孔g在第二平面的正投影至少部分重合,滑槽220在第二平面的正投影与第三轨道块2213的连接轴h在第二平面的正投影至少部分重合。
在其他可能的实施例中,滑槽220在第二平面的正投影也可以位于第一轨道块2211的连接孔g在第二平面的正投影靠近盖板11的一侧,同时,滑槽220在第二平面的正投影位于第三轨道块2213的连接孔g在第二平面的正投影靠近盖板11的一侧,滑槽220在第二平面的正投影位于第三轨道块2213的连接轴h在第二平面的正投影靠近盖板11的一侧。在这种实施例中,在平行于第一平面且垂直于柔性显示面板1的长度方向x的方向上,连接相邻两个第三轨道块2213、或者连接第三轨道块2213和第一轨道块2211的连接轴h的尺寸不影响柔性显示面板1。
本申请实施例所示的显示装置可以是一种车载显示装置,便于驾驶者使用。在不使用时可设置显示装置处于第一状态,即显示面为平面,以给车内更大的空间;而在驾驶时,驾驶者可以根据自己的身高及驾驶习惯等,设置显示装置向驾驶者弯曲变成弧形,使驾驶者看向屏幕时视线角度更大、有更舒适的视觉体验。相比之下,若在车内直接设置曲面显示装置,会导致曲面显示装置占据车内空间较大,用户体验感较差。
图13是本申请实施例提供的一种驾驶员观看分别处于第一状态和第二状态下的显示装置的示意图。如图13所示,在显示区域AA在柔性显示面板1的长度方向x上的尺寸相同的条件下,显示面为曲面时,驾驶者看向显示面时的视线与显示面形成的角度最小为α,显示面为平面时,驾驶者看向显示面时的视线与显示面形成的角度最小为β,α>β。在这种应用场景下,由于驾驶者只可能位于显示装置的一侧,因此显示面仅需要向靠近驾驶者的方向弯折即可。
示例性地,车载显示装置的显示区域包括仪表区和中控区两部分,中控区位于仪表区靠近固定部21的一侧。例如在驾驶时,在伸缩连杆23、支撑单元22和固定部21的配合下,可设置中控区向驾驶者弯曲变成弧形,还可以使得柔性显示面板滑动,将被机壳3遮挡的部分柔性显示面板1拉出,增大显示区域AA的面积,在这个过程中柔性显示面板如跑道般向前延伸,动态可变的弯曲弧度及显示区域的面积的调整可以赋予车辆更强的科技感和动态美感,给人以震撼的视觉冲击。
在一种可能的实施例中,结合图7、图8和图10,多个轨道块221中的至少部分轨道块221具有第一截面和第二截面,第一截面位于第二截面远离柔性显示面板1的显示面的一侧。在柔性显示面板1的长度方向x上,第二截面的尺寸k小于或者等于第一截面的尺寸j。当仅需要显示面从平面向一个方向弯折形成曲面时,可设置k小于或者等于j,以防止显示面反向弯折。对于图7、图8或图10中的轨道块,当第一截面和第二截面均位于轨道块的上半部分时,或者第一截面位于轨道块的下半部分、第二截面位于轨道块的上半部分时,在柔性显示面板1的长度方向x上,第二截面的尺寸k小于第一截面的尺寸j;当第一截面和第二截面均位于轨道块的下半部分时,第二截面的尺寸k等于第一截面的尺寸j。这里,上半部分是指轨道块中位于滑槽220靠近盖板11的一侧,下半部分是指轨道块中位于滑槽220远离盖板11的一侧。
需要说明的是,对于第一轨道块2211,在图7所示实施例中,第一轨道块2211的主体部分是指除连接孔g以外的其它部分;对于第二轨道块2212,在图8所示实施例中,第二轨道块2212是指除了条形柱b以外的其它部分;对于第三轨道块2213,在图10所示实施例中,第三轨道块是指除了连接孔g和连接轴h以外的其它部分。
需要说明的是,每个第三轨道块2213的形状可以不同,例如在图3或图4所示实施例中,距离固定部21最远的第三轨道块2213的上半部分形状与其他的第三轨道块2213的上半部分的形状不同。
在其他可能的实施例中,显示装置也可以是广告牌等产品,观看者可能位于相对显示装置而言的多个位置,因此柔性显示面板可能有两个弯折方向,以便于位于不同位置的观看者观看。在这种应用场景下,在柔性显示面板1的长度方向x上,第二截面的尺寸k可以不小于或者等于第一截面的尺寸j。而是:在柔性显示面板1的长度方向x上,轨道块的上半部分的尺寸小于轨道块上用于设置滑槽220处的尺寸,轨道块的下半部分的尺寸小于轨道块上用于设置滑槽220处的尺寸,以便于显示面双向弯折。这里,轨道块的上半部分、轨道块下半部分的含义在前文已做解释,此处不再赘述。
下面对柔性显示面板的结构作示例性说明。
图14和图15是本申请实施例提供的一种柔性显示面板分别在两个视角下的平面结构示意图。结合图1、图2、图14和图15所示,柔性显示面板包括背板11、盖板12和位于背板11和盖板12之间的显示结构13,其中背板11的相对的两个边缘分别位于两个支撑单元22的滑槽220内。
如图14和图15所示,显示结构13包括显示屏131。显示屏131可以为:液晶显示屏、OLED(Organic Light Emitting Diode,有机发光二极管)显示屏、QLED(Quantum Dot Light Emitting Diode,量子点发光二极管)显示屏等,本申请实施例在此不做具体限定。
示例性地,柔性显示面板1还包括与显示屏131相连的封装电路板14。可选地,如图14所示,封装电路板14可以为覆晶薄膜(Chip On Film,COF)电路板,封装电路板14包括薄膜电路板本体,也即COF薄膜(Film),薄膜电路板上具有驱动芯片15。在其他可能的实施例中,封装电路板14还可以为覆晶玻璃(Chip On Glass,COG)电路板或覆晶柔性材料(Chip On Pi,COP)电路板。示例性地,封装电路板14远离显示屏131的一端通过第一胶层140固定在显示屏130的背面。
示例性地,如图14所示,柔性显示面板还包括主板16,主板16与封装电路板14连接。主板16通过对封装电路板14上的驱动芯片15进行控制,进而控制显示屏131显示画面。示例性地,主板16通过第二胶层160固定在显示屏131的背面。
示例性地,如图14所示,显示结构13还包括偏光片132,偏光片132位于显示屏131靠近盖板12的一侧,即偏光片132位于显示屏131的出光面。显示结构还包括连接层133,连接层133的制作材料可以为光学透明胶(Optically Clear Adhesive,OCA),例如液态光学透明胶(Liquid Optical Clear Adhesive,LOCA)、热固化型光学透明热熔胶(Thermal-melt Optical Clear Adhesive,TOCA)。连接层133也可以采用其他具有粘合作用的材料制成,例如紫外固化胶。
示例性地,如图14所示,显示结构13还包括支撑片134,支撑片134位于显示屏131远离盖板12的一侧,即支撑片134位于显示屏131的背面,以对显示屏131起到支撑作用。
示例性地,如图14所示,显示结构还包括第一粘接层135和第二粘接层136,第一粘接层135用于连接支撑片134和显示屏131,第二粘接层136用于连接支撑片134和背板11。可选地,第一粘接层135和第二粘接层136均为PSA层。
图16是本申请实施例提供的一种背板的平面结构示意图。如图16所示,背板11具有在柔性显示面板的长度方向x上依次相连的第一区域111、第二区域112和第三区域113,第三区域113靠近固定部21。需要说明的是,图16中,标号220是为了示出在垂直于柔性显示面板的长度方向x上,柔性显示面板1中位于支撑单元22的滑槽220内的部分。
如图16所示,第二区域112具有多个第一镂空结构1120,多个第一镂空结构1120呈条状且延伸方向与柔性显示面板的长度方向x相交;第三区域113具有多个第二镂空结构1130,多个第二镂空结构1130成条状且延伸方向与柔性显示面板的长度方向x相同。由于第三区域既需要能够弯折,还需要能够带动整个柔性显示面板1运动,因此作图16所示的设计可以使得与固定部21相连的第三区域113具有一定的弯折性能(第三区域113的弯折性能介于第一区域111的弯折性能和第二区域112的弯折性能之间),并且使得第三区域113还具有一定的支撑力(第三区域113的支撑力介于第一区域111的支撑力和第二区域112的支撑力之间)。
图17是本申请实施例提供的一种显示装置的制作方法的流程示意图,如图17所示,方法包括:
步骤1701,提供支撑件和柔性显示面板。
步骤1702,连接支撑件和柔性显示面板。
其中,支撑件包括固定部、支撑单元和伸缩连杆,固定部与支撑单元的一端相连,固定部与柔性显示面板的一端固定连接,支撑单元与柔性显示面板滑动连接,支撑件用于支撑柔性显示面板在第一状态和第二状态中切换,柔性显示面板的显示面在第一状态下为平面,显示面在第二状态下为曲面,伸缩连杆与支撑单元相连,伸缩连杆的延伸方向与第一平面相交,第一平面为柔性显示面板的显示面在第一状态下所在的平面。
综上所述,本申请实施例提供的显示装置的制作方法,制作了一种包括柔性显示面板和支撑件的显示装置。其中,支撑件包括固定部、支撑单元和伸缩连杆。伸缩连杆的延伸方向与第一平面相交,伸缩连杆与支撑单元相连,支撑单元的一端与固定部相连,固定部与柔性显示面板的一端固定连接,因此伸缩连杆伸缩时,可以使得支撑单元的形状发生变化,并依次带动固定部、与固定部相连的柔性显示面板的一端的位置发生变化,使得柔性显示面板在第一状态和第二状态之间切换。由于柔性显示面板和支撑单元滑动连接,因此柔性显示面板在切换过程中产生的应力能够及时释放,利于延长柔性显示面板的使用寿命。
