Description

可调式曲面液晶显示面板试验装置及其操作方法 技术领域
本揭示涉及显示技术领域，特别涉及一种可调式曲面液晶显示面板试验装置及其操作方法。
 背景技术
在传统显示产品市场疲软之际，曲面产品是提高产品竞争力的关键技术之一。与平面显示产品相比，曲面屏幕由于液晶显示面板弯曲导致玻璃承受了一个成形应力。
目前的试验装置无法兼容不同长度L和宽度B、不同弯曲半径R及不同直线段l的设计方案，导致存在成本较高、浪费严重的问题。然而，目前的试验装置采用三点弯曲的近似方法得到弯曲半径R，但弯曲半径R与实际不符，精度不够。此外，目前的试验装置无法实现曲面液晶显示面板成形后几何尺寸的测定。另外在测试曲面液晶面板寿命时，由于破片所需时间较长，现有产品也无法监测破坏时间。
 技术问题
为解决上述技术问题，本发明提供一种可调式曲面液晶显示面板试验装置及其操作方法。
 技术解决方案
本发明揭示一种可调式曲面液晶显示面板试验装置，所述试验装置包含：支架组件，所述支架组件包含限位装置；多个滑轨支撑组件，至少一个滑轨支撑组件设置于所述限位装置上，其余滑轨支撑组件按照一定距离设置；多个短滑轨，所述短滑轨通过第一L形连接件及多个第一T形螺栓与所述滑轨支撑组件连接；多个长滑轨，所述长滑轨通过第二L形连接件及多个第二T形螺栓与所述短滑轨连接；传感器组件，所述传感器组件与滑轨支撑组件通过第三L形连接件及第三Ｔ形螺栓连接；多个短框条，所述短框条与所述短滑轨连接；多个长框条，所述长框条与所述长滑轨连接；以及T形尺，所述T形尺设置于所述滑轨支撑组件上。

在本申请的可调式曲面液晶显示面板试验装置中，所述短滑轨的一侧设有第二T形凹槽，相邻一侧设有第一燕尾槽，以及所述长滑轨的一侧设有第三T形凹槽，相邻一侧设有第二燕尾槽，其中，第一燕尾槽的下表面与第二燕尾槽槽的上表面平齐。
在本申请的可调式曲面液晶显示面板试验装置中，所述传感器组件整体左右对称，且所述传感器组件包含方钢、贯通槽滑轨、传感器及U形连接件。
在本申请的可调式曲面液晶显示面板试验装置中，所述方钢与所述U形连接件透过销钉连接，所述U形连接件透过第一螺栓与所述贯通槽滑轨连接，以及所述贯通槽滑轨透过平直连接件和多个第二螺栓与所述传感器连接。
在本申请的可调式曲面液晶显示面板试验装置中，短框条的底端为第一燕尾部，且所述第一燕尾部与所述第一燕尾槽相符，以及所述长框条的底端为第二燕尾部，且所述第二燕尾部与所述第二燕尾槽相符，其中，短框条的上表面和长框条的上表面平齐。
在本申请的可调式曲面液晶显示面板试验装置中，所述T形尺包含有刻度的水平尺及垂直尺，且所述水平尺可以在所述垂直尺端部方孔中滑动。
本发明揭示一种可调式曲面液晶显示面板试验装置的操作方法，所述操作方法包含下列步骤：提供一液晶显示面板，所述液晶显示面板长度为L，且宽度为B；提供边框胶带，所述边框胶带宽度为b；设定曲面设定参数，所述曲面设定参数包含直线段l和中间段弯曲半径R；调整各个短滑轨在滑轨支撑组件上的安装位置，以确保各个长框条的距离为B-2b；调整各个所述长滑轨在所述短滑轨上的安装位置，以确保所述长滑轨安装在所述液晶显示面板一侧的伸出长度与所述直线段l一致；调整所述滑轨支撑组件，以确保各个所述短框条距离为L-2b；调整传感器组件中的方钢在所述滑轨支撑组件上的安装位置，以使得所述方钢处于所述液晶显示面板B/2处，并拧紧所述传感器组件两端的贯通槽滑轨与U形连接件的第一螺栓；调整所述短滑轨的第一燕尾槽的各个所述短框条和所述长滑轨的第二燕尾槽中的各个所述长框条，且相邻的所述短框条和所述长框条相互接触以形成长方形边框区域；粘贴所述液晶显示面板于所述长方形边框区域上；撤掉内侧的各个所述滑轨支撑组件；调整T形尺，以使得所述T形尺中的垂直尺位于所述液晶显示面板L/2处；拧松所述传感器组件的所述贯通槽滑轨与所述U形连接的所述第一螺栓；沿所述贯通槽滑轨滑动所述U形连接件，同时微调所述T形尺；以及通过有角度测量刻度的滑轨支撑组件，测量液晶显示面板直线段l的旋转角度α，且监测传感器测量的力F。
在本申请的可调式曲面液晶显示面板试验装置的操作方法中，当沿所述贯通槽滑轨滑动所述U形连接件，同时微调所述T形尺，通过分别测量弯曲前后的液晶显示面板刻度h0和h1，得到弯曲高度h=h1-h0，当h达到所述弯曲半径R对应的弯曲高度时，停止移动并拧紧所述第一螺栓予以固定。
在本申请的可调式曲面液晶显示面板试验装置的操作方法中，所述传感器测量的力F出现波动，从开始监测到该波动出现的持续时间为所述液晶显示面板的寿命。
 有益效果
首先，所述试验装置能适用于不同尺寸的液晶显示面板，即不同长度L和宽度B的液晶显示面板，液晶显示面板的短边最小尺寸大于短滑轨的2倍即可，最大尺寸无限制，而液晶显示面板的长边最小尺寸无限制，通过延长滑轨支撑组件也可实现长边任意长度的最大尺寸。
第二，所述试验装置也能够适用不同的直线段l的液晶显示面板，即液晶显示面板中直线段l在长边L中的不同占比是一个重要设计参数，由于长滑轨的刚度远大于边框条和液晶显示面板刚度之和，因此在弯曲后长滑轨仍保持直线形式。
第三，所述试验装置还能够适用不同中间弯曲半径R的液晶显示面板，即液晶显示面板的中间弯曲段与长边框的合成截面是等截面结构，而等截面结构在受到弯矩作用时的变形为圆弧，因此通过调节试验装置可以精确地达到任意弯曲半径R。
第四，所述试验装置可以测量直线段弯曲后的旋转角度α和拱高h。通过拱高h，直线段长度l，液晶显示面板长边长度L，以及旋转角度α可以计算弯曲半径R。此外，可以精确监测曲面液晶显示面板的断裂时间，测量使用寿命。
再者，所述试验装置可以用来测试粘贴胶带在曲面液晶显示面板中的实际使用强度和脱胶寿命；原理同玻璃断裂，当胶带脱胶或断裂时，传感器测量的力F将出现变化。此外，如果试验时不需考虑胶带的影响，可在长框条、短框条侧边设计方形槽，试验时将液晶面板嵌入该槽内，可以避免使用胶带。
最后，通过所述试验装置适应所有曲面液晶显示面板的试验，显着降低了开模费用和试验周期，且提高了试验精度。

S70：调整所述短滑轨3的第一燕尾槽32的各个所述短框条6和所述长滑轨4的第二燕尾槽42中的各个所述长框条7，且相邻的所述短框条6和所述长框条7相互接触以形成长方形边框区域。
S80：粘贴所述液晶显示面板9于所述长方形边框区域上。
S90：撤掉内侧的各个所述滑轨支撑组件2。
S100：调整T形尺8，以使得所述T形尺8中的垂直尺82位于所述液晶显示面板9的L/2处。
S110：拧松所述传感器组件5的所述贯通槽滑轨52与所述U形连接54的所述第一螺栓571。
S120：沿所述贯通槽滑轨滑动所述U形连接件，同时微调所述T形尺。
S130：通过有角度测量刻度的滑轨支撑组件2，测量液晶显示面板9直线段l的旋转角度α，且监测传感器53测量的力F。
进一步，如图10所示，当沿所述贯通槽滑轨52滑动所述U形连接件54，同时微调所述T形尺8，通过分别测量弯曲前后的液晶显示面板9的刻度h0和h1，得到弯曲高度h=h1-h0，当h达到所述弯曲半径R对应的弯曲高度时，停止移动并拧紧所述第一螺栓予以固定。
进一步，面板弯曲后固定，F则保持不变，直到面板出现静态断裂时则出现较大的波动，所述传感器53测量的力F则出现波动。如果液晶显示面板9达到寿命而断裂，则F会出现波动，从测量开始到该波动出现时间即寿命，即从测量开始到该波动出现时的持续时间为所述液晶显示面板9的寿命。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
