Description

本发明的实施例涉及一种曲面显示屏曲率调节装置、曲面显示屏曲率调节方法、曲面显示装置。
背景技术
曲面显示屏的制造中，尤其在大尺寸曲面显示屏的制造中，最常用可行的一种方法是，在平板显示面板两端直接施加外力，比如将显示面板置于弯曲的模组框架结构中，通过模组框架的外力抵消显示面板回弹力，使显示面板保持在弯曲形态。如图1所示，使用预先弯曲的支撑背板1，不仅可以支撑显示面板的重量，而且在显示面板与支撑背板1组装后显示面板弯曲产生的回弹力由预弯曲的支撑背板1来抵消，最终使得整个显示屏2达到一个稳定的弯曲半径。通常地，弯曲的支撑背板1是弧线型，并且被预弯曲到一个较小的曲率。但是，弧形的形状、预弯曲的曲率、背板的厚度、背板材料的密度均匀性等都是固定的；对于同一显示面板，实现不同曲率的显示屏2需要不同曲率的支撑背板1，不利于降低制造成本且不利于产品管理。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合附图，对本发明实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本发明的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例提供了一种曲面显示屏曲率调节装置及其使用方法、曲面显示装置。在本发明实施例的技术方案中，通过可弹性形变的弹性背板实现显示屏的弯曲，使得曲面显示屏曲率调节装置可以将显示屏弯曲成不同的曲率，提高了曲面显示屏曲率调节装置的适用性。为了方便对本发明实施例的技术方案的理解，下面结合附图对本发明实施例的技术方案进行详细的说明。
图2示出了本发明实施例提供的曲面显示屏曲率调节装置。如图2所示，本发明实施例提供了一种曲面显示屏曲率调节装置，该装置包括：
支撑背板10，为具有固定的曲率的支撑板；
弹性背板20，与支撑背板10连接并为可发生弹性形变以改变曲率的板；
调整装置，用于调节弹性背板20曲率。
在本发明的实施例中，通过采用调整装置调节弹性背板20的曲率，从而使得弹性背板20可以将显示屏30弯曲成不同的曲率，提高了曲面显示屏曲率调节装置的适用性。
在本发明实施例中，如图2所示，支撑背板10为一块基板，弹性背板20可以发生弹性形变从而改变其自身的曲率，弹性背板20与显示屏30固定连接。在本发明实施例中，需要弯曲显示屏30时，首先将显示屏30固定在弹性背板20上，之后通过调整装置调整弹性背板20的曲率，从而改变显示屏30弯曲的曲率。
调整装置可以采用不同的结构来实现，为了方便对本发明实施例提供的曲面显示屏曲率调节装置的理解，下面详细对其进行说明。
一并参考图2～图5，其中，图2与图3示出了本发明实施例中的曲面显示屏曲率调节装置在不同工作状态时的示意图，图4及图5示出了本发明实施例提供的调整装置在不同工作状态的示意图。
例如，如图2和图3所示，显示屏30固定在弹性背板20上，支撑背板10设置在弹性背板20背离显示屏30的一侧(换言之，弹性背板20设置在支撑背板10的朝向显示屏30的一侧)，弹性背板20的中心与支撑背板10固定连接，调整装置包含两个调整部40，所述两个调整部40分别设置在所述弹性背板20的两端并位于弹性背板20和支撑背板10之间。
例如，弹性背板20与支撑背板10之间可以选择不同的连接方式，如焊接、紧固件连接或者粘接。作为示例，弹性背板20的中心与支撑背板10之间的固定方式为粘接连接。
例如，调整部40为可锁定在设定位置的伸缩装置，且在所述伸缩装置伸出时，所述弹性背板的曲率变大。该类装置可以有多种，如螺旋机构、齿条机构、驱动气缸、驱动液压缸等。
在一个实施例中，如图4及图5所示，伸缩装置例如包括：分别与弹性背板20及支撑背板10活动连接(例如，铰接)的两个支撑块44；两个连杆组，每个连杆组包括第一连杆41及与第一连杆41活动连接(例如，铰接)的第二连杆42，且第一连杆41及第二连杆42分别与两个支撑块44活动连 接(例如，铰接)；第一连杆41及第二连杆42的连接处设置有螺纹孔，且两个连杆组的螺纹孔的螺纹旋向相反；螺旋杆43，与两个连杆组的螺纹孔螺旋连接。例如，第一连杆41及第二连杆42铰接，将第一连杆41与第二连杆42进行铰接的铰链与螺旋孔交叉。
在图4及图5所示的伸缩装置中，两个连杆组形成菱形结构，通过螺旋杆43的螺旋改变菱形的形状，从而改变弹性背板20的两端距离支撑背板10的距离。图4所示的伸缩装置所处的状态为对应图2时的状态，弹性背板20紧贴在支撑背板10的朝向显示屏的一面，此时，弹性背板20具有较小的曲率。当需要调整弹性背板20时，沿图4所示的旋转方向，旋转螺旋杆43，最终形成如图5所示的状态；此时，弹性背板20两端与支撑背板10两端的距离增大，如图3所示，弹性背板20的两端被伸缩装置顶起，弹性背板20的曲率变大，进而使得显示屏30的曲率变大。
在一个实施例中，如图6所示，伸缩装置例如包括：分别与弹性背板20及支撑背板10活动连接(例如，铰接)的两个螺旋杆，且两个螺旋杆上的螺纹的螺旋方向相反，位于两个螺旋杆之间且分别与两个螺旋杆螺旋连接的螺纹套47。例如，如图6所示，两个螺旋杆分别为第一螺旋杆45和第二螺旋杆46，其中，第一螺旋杆45远离螺纹套47的一端与弹性背板20活动连接(例如，铰接)，第二螺旋杆46远离螺纹套47的一端与支撑背板10活动连接(例如，铰接)。即采用一种螺旋机构作为伸缩装置来调整弹性背板20的曲率。由于第一螺旋杆45和第二螺旋杆46上的螺纹旋向相反，因此，在螺纹套47朝向一个方向旋转时，第一螺旋杆45及第二螺旋杆46会从螺纹套47内同时旋出或旋入。由于弹性背板20的中心位置与支撑背板10固定连接，因此，在第一螺旋杆45及第二螺旋杆46从螺纹套47内旋出时，弹性背板20的曲率变大，在第一螺旋杆45及第二螺旋杆46同时旋入螺纹套47内时，弹性背板20的曲率变小。这样一来，弹性背板20可以弯成不同的曲率，进而将显示屏30弯成不同的曲率。
例如，如图7及图8所示，调整装置包括：助力支撑背板51；固定柱50，固定柱50的两端分别与助力背板51的端部及弹性背板20的端部固定连接，固定柱50上沿其长度方向设置有多个锁定孔53；其中，助力支撑背板51及弹性背板20分别位于支撑背板10的两侧，支撑背板10上设置有与锁定孔 53相配合的定位柱54，且在不同的锁定孔53与所述定位柱54配合时，弹性背板20的曲率发生改变。
如图7及图8所示，助力支撑背板51、两个固定柱50以及弹性背板20形成一个框架结构，支撑背板10设置在该框架结构内。例如，助力支撑背板51及弹性背板20均采用弹性材料制作而成，因此，助力支撑背板51及弹性背板20均可发生形变。在固定柱50上沿其长度方向设置了多个锁定孔53，且支撑背板10上设置了与锁定孔53相配合的定位柱54，当定位柱54卡装在不同位置的锁定孔53时，弹性背板20及助力支撑背板51发生不同程度的形变。图7及图8示出了定位柱54卡装在不同锁定孔53内时曲面显示屏曲率调节装置的不同工作状态。如图7所示，弹性背板20整个贴附在支撑背板10的朝向显示屏的一面。如图8所示，当改变定位柱54的位置时，弹性背板20的曲率发生了改变。
为了保证弹性背板20曲率发生改变时曲率变化比较均匀，例如助力支撑背板51朝向弹性背板20的一面设置有支撑柱52，支撑柱52穿设过支撑背板10抵压在弹性背板20。如图8所示，支撑柱52顶在弹性背板20朝向支撑背板10的一侧。进一步地，例如，弹性背板20上设置有与支撑柱52相配合的弧形凹陷结构，保证了两者的配合。
通过上述描述可以看出，本发明实施例提供的曲面显示屏曲率调节装置可以选择不同的调整装置，只需其能够改变弹性背板20的曲率并能够将弹性背板20锁定到期望的位置，使得曲面显示屏曲率调节装置调节显示屏30具有不同曲率即可。应当理解的是，本发明实施例提供的调整装置不仅限于上述实施例提供的调整装置，其他任何能够实现上述功能的调整装置均可以应用到本发明实施例中。
本发明实施例还提供了一种曲面显示屏曲率调节方法，该调节方法使用上述曲面显示屏曲率调节装置调节曲面显示屏的曲率。例如，该方法包括以下步骤：
将显示屏与弹性背板固定连接；
通过调整装置调整弹性背板的曲率以使得固定在所述弹性背板上的显示屏弯曲。
在本发明实施例中，通过采用调整装置调节弹性背板的曲率，从而使得 弹性背板可以将显示屏弯曲成不同的曲率，提高了曲面显示屏曲率调节装置的适用性，方便调整显示屏的曲率。需要说明的是，在曲面显示屏调节装置的调整装置选择不同的结构时，其对应的调整的方法也相应进行变动，具体可以参见图4至图8的描述，在此不再赘述。
本发明实施例还提供了一种曲面显示装置，该曲面显示装置包括上述曲面显示屏曲率调节装置及显示屏，所述显示屏与所述弹性背板固定连接。
在本发明实施例中，通过采用调整装置调节弹性背板的曲率，从而使得弹性背板可以将显示屏弯曲成不同的曲率，提高了曲面显示屏曲率调节装置的适用性，同时使得曲面显示装置可以实现不同的曲率。
以上所述仅是本发明的示范性实施方式，而非用于限制本发明的保护范围，本发明的保护范围由所附的权利要求确定。
