Description

柔性OLED手机模组 技术领域
本发明涉及显示技术领域，尤其涉及一种柔性OLED手机模组。
 背景技术
薄膜晶体管（Thin Film Transistor，TFT）是目前液晶显示装置（Liquid Crystal Display，LCD）和有源矩阵驱动式有机电致发光显示装置（Active Matrix Organic Light-Emitting Diode，AMOLED）中的主要驱动元件，直接关系平板显示装置的显示性能。
现有市场上的液晶显示器大部分为背光型液晶显示器，其包括液晶显示面板及背光模组（backlight module）。液晶显示面板的工作原理是在薄膜晶体管阵列基板（Thin Film Transistor Array Substrate，TFT Array Substrate）与彩色滤光片（Color Filter，CF）基板之间灌入液晶分子，并在两片基板上分别施加像素电压和公共电压，通过像素电压和公共电压之间形成的电场控制液晶分子的旋转方向，以将背光模组的光线透射出来产生画面。
OLED器件通常包括：基板、设于基板上的阳极、设于阳极上的空穴注入层、设于空穴注入层上的空穴传输层、设于空穴传输层上的发光层、设于发光层上的电子传输层、设于电子传输层上的电子注入层及设于电子注入层上的阴极。OLED器件的发光原理为半导体材料和有机发光材料在电场驱动下，通过载流子注入和复合导致发光。具体的，OLED器件通常采用氧化铟锡(ITO)电极和金属电极分别作为器件的阳极和阴极，在一定电压驱动下，电子和空穴分别从阴极和阳极注入到电子传输层和空穴传输层，电子和空穴分别经过电子传输层和空穴传输层迁移到发光层，并在发光层中相遇，形成激子并使发光分子激发，后者经过辐射弛豫而发出可见光。
近年来，OLED显示技术正在手机与电视市场逐步普及,良品率有了大幅提升,其下一代显示技术的地位已无可撼动，而基于OLED的柔性显示技术则是未来显示技术的一个重要研发方向。与LCD液晶屏以及硬性OLED屏幕不同，柔性OLED屏为了实现弯折，其受到落球冲击的外表面无法用较厚的盖板玻璃（Cover Glass），而应该使用很薄的柔性盖板，那么柔性OLED屏抗落球冲击能力较差。

 本发明的实施方式
为更进一步阐述本发明所采取的技术手段及其效果，以下结合本发明的优选实施例及其附图进行详细描述。
请参阅图 1 ，本发明提供一种柔性 OLED 手机模组，包括：中框（ Mid Frame ） 10 、贴附于所述中框 10 上的柔性 OLED 面板 20 、与所述中框 10 连接的背板（ Back Cove ） 30 以及设于所述中框 10 与背板 30 之间的缓冲层 40 ；
所述缓冲层 40 用于吸收柔性 OLED 面板 20 上受到的冲击力。
需要说明的是，本发明通过在中框 10 与背板 30 之间设置缓冲层 40 ，当柔性 OLED 面板 20 上方受到钢球等冲击时，冲击力可以通过中框 10 传递给缓冲层 40 ，该缓冲层 40 可以吸收大部分能量，使中框 10 与背板 30 之间不会发生剧烈的冲击，从而保护柔性 OLED 面板 20 ，提高柔性 OLED 手机模组的抗冲击强度。
具体的，请参阅图 2 ，所述柔性 OLED 面板 20 包括弯折区 21 、位于所述弯折区 21 一侧的第一非弯折区 22 以及位于所述弯折区 21 另一侧的第二非弯折区 23 ；
所述中框 10 包括对应所述第一非弯折区 22 的第一中框部 11 以及对应所述第二非弯折区 23 的第二中框部 12 （即中框 10 对应弯折区 21 的部分为空）；
所述第一非弯折区 22 贴附于第一中框部 11 上；所述第二非弯折区 23 贴附于第二中框部 12 上。
具体的，请参阅图 3 ，假设柔性 OLED 面板 20 的弯折半径为 R ，则弯折区 21 的长度 L0= π R ，当以弯折区 21 的中心进行弯折时，柔性 OLED 面板 20 两侧的展平状态与弯折状态的长度改变量△ L 均为π R/2-R 。
具体的，所述背板 30 包括对应所述第一非弯折区 22 的第一背板部 31 、对应所述第二非弯折区 23 的第二背板部 32 、对应所述弯折区 21 的铰链 33 、与所述第一背板部 31 滑动连接的第一滑动弹簧 34 以及与所述第二背板部 32 滑动连接的第二滑动弹簧 35 ，通过铰链 33 固定连接第一滑动弹簧 34 与第二滑动弹簧 35 ，在柔性 OLED 面板 20 弯折时，对应所述弯折区 21 的铰链 33 随之弯折，第一滑动弹簧 34 面向第一背板部 31 的方向进行滑动，第二滑动弹簧 35 面向第二背板部 32 的方向进行滑动，以补偿柔性 OLED 面板 20 弯折状态与展平状态的长度改变量π R/2-R ，使弯折区 21 不会受到拉扯力，实现柔性 OLED 手机模组的弯折。
进一步的，请参阅图 4 ，所述第一背板部 31 对应第一滑动弹簧 34 设有第一凸起 311 ，所述第一滑动弹簧 34 对应第一凸起 311 设有第一凹槽 341 ；所述第二背板部 32 对应第二滑动弹簧 35 设有第二凸起 321 ，所述第二滑动弹簧 35 对应第二凸起 321 设有第二凹槽 351 ；通过第一凸起 311 与第一凹槽 341 配合滑动连接所述第一背板部 31 与第一滑动弹簧 34 ；通过第二凸起 321 与第二凹槽 351 配合滑动连接所述第二背板部 32 与第二滑动弹簧 35 。
具体的，所述第一背板部 31 与第一中框部 11 通过螺丝连接；所述第二背板部 32 与第二中框部 12 通过螺丝连接。
具体的，所述缓冲层 40 为橡胶垫片（ Rubber Gasket ），由于橡胶垫片具有超弹性大变形，可以吸收大部分能量。
具体的，请参阅图 1 及图 5 ，所述缓冲层 40 包括设于所述第一背板部 31 与第一中框部 11 之间的第一缓冲部 41 以及设于所述第二背板部 32 与第二中框部 12 的第二缓冲部 42 ；所述第一缓冲部 41 的形状为“一”字形，所述第二缓冲部 42 的形状为“ U ” 字形；
由于中框 10 的第一中框部 11 需要预留位置设置柔性电路板等器件，因此留给第一缓冲部 41 的空间不足，只能将所述第一缓冲部 41 的形状设置为“一”字形，而中框 10 的第二中框部 12 留给第二缓冲部 42 的空间足够，可以将所述第二缓冲部 42 的形状设置为“ U ” 字形。
进一步的，所述第一中框部 11 中设有容纳第一缓冲部 41 的第三凹槽；所述第二中框部 12 中设有容纳第二缓冲部 42 的第四凹槽，将第一缓冲部 41 置于第三凹槽中，以及第二缓冲部 42 置于第四凹槽中可以减少柔性 OLED 手机模组的厚度。
具体的，所述第三凹槽的深度小于第一缓冲部 41 的厚度；所述第四凹槽的深度小于第二缓冲部 42 的厚度，以达到较好的减震效果。
具体的，请参阅图 6 及图 7 ，所述缓冲层 40 的横截面形状为矩形或者锯齿形；横截面形状为锯齿形的缓冲层 40 的减震效果会比矩形更好。
请参阅图 8 ，横坐标为时间，纵坐标为应力；为了进一步验证本发明的缓冲层 40 提高柔性 OLED 手机模组的抗冲击强度的优越性，将现有的没有设置缓冲层 40 的柔性 OLED 手机模组与本发明的设置了缓冲层 40 的柔性 OLED 手机模组分别进行落球仿真测试，得到柔性 OLED 面板 20 中的关键器件（ TFT 阵列基板）的应力曲线，将没有设置缓冲层 40 的柔性 OLED 手机模组中的 TFT 阵列基板的应力曲线与设置了缓冲层 40 的柔性 OLED 手机模组中的 TFT 阵列基板的应力曲线进行对比，通过图 8 可以得知，设置了缓冲层 40 的柔性 OLED 手机模组中的 TFT 阵列基板受到的应力明显小于没有设置缓冲层 40 的柔性 OLED 手机模组中的 TFT 阵列基板的应力。
综上所述，本发明的柔性 OLED 手机模组包括：中框、贴附于所述中框上的柔性 OLED 面板、与所述中框连接的背板以及设于所述中框与背板之间的缓冲层；所述缓冲层用于吸收柔性 OLED 面板上受到的冲击力，当柔性 OLED 面板上方受到钢球等冲击时，冲击力可以通过中框传递给缓冲层，该缓冲层可以吸收大部分能量，使中框与背板之间不会发生剧烈的冲击，从而保护柔性 OLED 面板，提高柔性 OLED 手机模组的抗冲击强度。
以上所述，对于本领域的普通技术人员来说，可以根据本发明的技术方案和技术构思作出其他各种相应的改变和变形，而所有这些改变和变形都应属于本发明权利要求的保护范围。
