Description

中框及显示装置 技术领域
本申请涉及显示领域，具体涉及一种中框及显示装置。
 背景技术
目前，随着显示技术的发展，人们对消费性电子产品的要求已经不单单局限于功能性，同时也更转向于设计性、艺术性以及具有良好的视觉体验性方面，比如当前盛行的超窄边框显示产品。
其中，随着超窄边框背光模组越来越极限，显示装置的中框的宽度也越来越小。由于中框变窄，在框胶贴合的时候，会出现因胶水太少而导致开胶的现象，以及因胶水溢胶进入显示区而影响显示效果的现象。框胶贴合品质的可靠性已成为框胶贴合方案的难点。
因此，如何防止因显示装置的中框变窄而影响框胶的贴合品质是面板厂家需要攻克的难关。

本申请实施例提供一种显示面板的中框及显示装置。以下分别进行详细说明。需说明的是，以下实施例的描述顺序不作为对实施例优选顺序的限定。
请参阅图1和图2，图1为本申请实施例提供的中框的第一种实施方式的结构示意图，图2为图1提供的中框的A处结构局部示意图。本申请实施例提供的中框100包括贴合面100a、外侧面100b和内侧面100c。贴合面100a位于外侧面100b和内侧面100c之间。外侧面100b和内侧面100c相对设置；
贴合面100a上设置有引流槽101。外侧面100b上设置有导流槽102和储胶槽103。导流槽102的一端与引流槽101连通。导流槽102的另一端与储胶槽103连接。引流槽101的宽度小于导流槽102的宽度。导流槽102的宽度小于储胶槽103的宽度。
需要说明的是，贴合面100a为中框100涂布框胶的一面。外侧面100b为中框100远离所述显示区的一面。内侧面100c为中框100靠近显示区的一面。
毛细现象中液体上升的高度可由如下所述的毛细现象原理公式得出。
H=(2σcosθ)/ρgR
其中，H为毛细现象中液体上升的高度，σ为表面张力，θ为液体表面与毛细管壁的夹角，ρ为液体的密度，g为重力加速度，R为毛细管的半径。需要说明的，θ取决于液体的种类、毛细管壁的材料和与液体接触的气体的种类等因素。
需要说明的是，当框胶滴在中框100的贴合面100a后。此时中框100的贴合面100a可近似为一个半径无限大的沟槽。因此根据毛细现象原理，框胶会由中框100的贴合面100a流向引流槽101。而当引流槽101填满后，框胶会流向与之连接的导流槽102，接着流向储胶槽103。
需要说明的是，储胶槽103可以起到临时存储框胶的作用。从而可以防止当框胶过多时，框胶溢流进入显示区。进而避免因框胶遮挡显示画面像素造成的显示不良现象的发生。
引流槽101的宽度W1小于导流槽102的宽度W2。导流槽102的宽度W2小于储胶槽103的宽度W3。
需要说明的是，在将显示模组与中框100安装在一起时，中框100的贴合面100a与显示模组之间有极小的缝隙。此缝隙可近似于一个半径无限小的沟槽。因此根据毛细现象原理，框胶会从储胶槽103流向导流槽102，接着从储胶槽103流向引流槽101，最后从引流槽101流向中框100的贴合面100a，直至显示模组和中框100完全贴合。由于中框100的贴合面100a与显示模组之间的缝隙可以完全被框胶填充，从而可以最大程度上保证贴合面积，进而可以提高框胶贴合的可靠性。
导流槽102包括相对设置的第一端102a和第二端102b。第一端102a为导流槽102靠近贴合面100a的一端。第二端102b为导流槽102远离贴合面100a的一端。导流槽102的宽度W2沿着第一端102a至第二端102b的方向逐渐增大。
需要说明的是，在将显示模组与中框100安装在一起时，需要使框胶从储胶槽103流向导流槽102，并经导流槽102流向引流槽101。而在这个过程中，框胶是从导流槽102远离贴合面100a的一端流向导流槽102靠近贴合面100a的一端。根据毛细现象，框胶会从半径比较大的沟槽流向半径比较小的沟槽。因此，使导流槽102的宽度W2沿着第一端102a至第二端102b的方向逐渐增大，有助于使框胶从导流槽102的第二端102b流向导流槽102的第一端102a，便于框胶将中框100的贴合面100a与显示模组之间的缝隙可以完全填充，进而可以最大程度上保证贴合面积，提高框胶贴合的可靠性。
引流槽101的一端延伸至外侧面100b。引流槽101的另一端延伸至内侧面100c。
需要说明的是，使引流槽101的一端延伸至外侧面100b，引流槽101的另一端延伸至内侧面100c，可以避免框胶在贴合面100a的某处聚集。
引流槽101垂直于中框100的外侧面100b。导流槽102垂直于中框100的贴合面100a。储胶槽103垂直于所述导流槽102。
需要说明的是，当框胶从储胶槽103流向导流槽102，并经导流槽102流向引流槽101时，根据毛细现象，需要克服的力为框胶的重力。因此使引流槽101垂直于中框100的外侧面100b，导流槽102垂直于中框100的贴合面100a，储胶槽103垂直于所述导流槽102，从而能在保证引流槽101、导流槽102和储胶槽103宽度不变的情况下，使更多的框胶能经储胶槽103流向导流槽102，并经导流槽102流向引流槽101。采用上述设置可以提高引流槽101、导流槽102和储胶槽103储存框胶的数量，有助于防止框胶过量溢流进入其他区域而影响显示装置的显示效果。
引流槽101的宽度W1为0.04毫米至0.2毫米。具体地，引流槽101的宽度W1为0.04毫米、0.06毫米、0.08毫米、0.11毫米、0.14毫米、0.17毫米或0.2毫秒。引流槽101的具体宽度W1由显示模组的中框100的工艺需求所确定。
导流槽102的宽度W2为0.04毫米至0.2毫米。具体地，导流槽102的宽度W2为0.04毫米、0.06毫米、0.08毫米、0.11毫米、0.14毫米、0.17毫米或0.2毫秒。导流槽102的具体宽度W2由显示模组的中框100的工艺需求所确定。
储胶槽103的宽度W3为0.04毫米至0.2毫米。具体地，储胶槽103的宽度W3为0.04毫米、0.06毫米、0.08毫米、0.11毫米、0.14毫米、0.17毫米或0.2毫秒。储胶槽103的具体宽度W3由显示模组的中框100的工艺需求所确定。
需要说明的是，引流槽101设置有多个，且多个引流槽101相互平行。引流槽101的间距D1为3毫米至5毫米。具体地，引流槽101的间距D1为3毫米、3.2毫米、3.4毫米、3.7毫米、4毫米、4.5毫米或5毫秒。引流槽101的具体间距D1由显示模组的中框100的工艺需求所确定。
引流槽101、导流槽102和储胶槽103的横截面的形状为矩形、梯形或半圆形。从单位体积面积表面能以及工艺角度考量，当引流槽101、导流槽102和储胶槽103的横截面的形状为半圆形时，框胶贴合的可靠性最高。
请参阅图3和图4，图3为本申请实施例提供的中框的第二种实施方式的结构示意图，图4为本申请实施例提供的中框的第二种实施方式的俯视图。如图3和图4所示，图3提供的中框与图1提供的中框的区别在于：贴合面100a靠近外侧面100b的一侧上设置有辅助引流槽104。辅助引流槽104与引流槽101连通。
辅助引流槽104的宽度W4等于引流槽101的宽度W1。由于导流槽102的宽度W2大于引流槽101的宽度W1，因此导流槽102的宽度W2也大于辅助引流槽104的宽度W4。
需要说明的是，在框胶用于将显示模组与中框100安装在一起时，是由引流槽101流向中框100的贴合面100a。框胶在经导流槽102流向引流槽101时，由于导流槽102的宽度W2也大于辅助引流槽104的宽度W4，因此根据毛细现象原理，部分框胶也会经导流槽102流向辅助引流槽104。
另外，辅助引流槽104的宽度W4等于引流槽101的宽度W1。引流槽101不会夺取导流槽102流向辅助引流槽104的框胶。辅助引流槽104也不会夺取导流槽102流向引流槽101的框胶。因此，通过设置辅助引流槽104可以提升框胶浸润中框100的贴合面100a和中框100的贴合面100a与显示模组间缝隙的速度。
需要说明的是，引流槽101设置有多个。辅助引流槽104与至少一个引流槽101连通。当辅助引流槽104与所有的引流槽101均连通时，辅助引流槽104提升框胶浸润中框100的贴合面100a和中框100的贴合面100a与显示模组间缝隙的速度的效果最好。
辅助引流槽104垂直于引流槽101。辅助引流槽104的宽度W1为0.04毫米至0.2毫米。具体地，辅助引流槽104的宽度W1为0.04毫米、0.06毫米、0.08毫米、0.11毫米、0.14毫米、0.17毫米或0.2毫秒。辅助引流槽104的具体宽度W1由显示模组的中框100的工艺需求所确定。
请参阅图5和图6，图5为本申请实施例提供的中框的第三种实施方式的结构示意图，图6为本申请实施例提供的中框的第三种实施方式的左视图。图5提供的中框与图1提供的中框的区别在于：外侧面100b上设置有辅助储胶槽105。辅助储胶槽105位于储胶槽103靠近贴合面100a的一侧，且辅助储胶槽105和导流槽102连通。辅助储胶槽105的宽度W5大于储胶槽103的宽度W2。
需要说明的是，由于用于中框100和显示模组贴合的框胶量较大，因此引流槽101、导流槽102和储胶槽103不一定能够将框胶完全储存起来。而多个辅助储胶槽105均与导流槽102连通，能够提高中框100存储框胶的量。因此辅助储胶槽105可以防止框胶溢流进入其他区域，防止其影响显示模组的显示效果，还可以最大程度上保证贴合面积，提高框胶贴合的可靠性。
另外，根据毛细现象原理公式可知，液体上升的高度是有限制的。通过设置多个位于储胶槽103靠近贴合面100a的一侧的辅助储胶槽105，可以降低导流槽102中框胶需要上升的高度。因此辅助储胶槽105可以防止导流槽102中的框胶因受到的拉力不足，而不能流入引流槽101，从而提高了框胶贴合的可靠性。
需要说明的是，辅助储胶槽105垂直于导流槽102。辅助储胶槽105的宽度W5为0.04毫米至0.2毫米。具体地，辅助储胶槽105的宽度W5为0.04毫米、0.06毫米、0.08毫米、0.11毫米、0.14毫米、0.17毫米或0.2毫秒。辅助储胶槽105的具体宽度W5由显示模组的中框100的工艺需求所确定。
请参阅图7和图8，图7为本申请实施例提供的中框的第四种实施方式的结构示意图，图8为本申请实施例提供的中框的第四种实施方式的俯视图。图7提供的中框与图5提供的中框的区别在于：贴合面100a还设置有辅助导流槽106，且辅助导流槽106与引流槽101连通。辅助导流槽106的宽度W6小于导流槽102的宽度W2。
需要说明的是，在框胶用于将显示模组与中框100安装在一起时，中框100的贴合面100a与显示模组之间有极小的缝隙。缝隙可近似于一个半径无限小的沟槽。因此根据毛细现象原理，框胶不仅会从引流槽101和辅助引流槽104流向中框100的贴合面100a，也会从辅助导流槽106流向中框100的贴合面100a，直至显示模组和中框100完全贴合。因此辅助导流槽106可以提升框胶浸润中框100的贴合面100a和中框100的贴合面100a与显示模组间缝隙的速度。
在将框胶滴在中框100的贴合面100a后，此时中框100的贴合面100a可近似为一个半径无限大的沟槽。因此根据毛细现象原理，框胶会由中框100的贴合面100a流向引流槽101、辅助引流槽104和辅助导流槽106。另外辅助导流槽106的宽度W6小于导流槽102的宽度W2。导流槽102也不会夺取流向辅助导流槽106的框胶。因此辅助导流槽106能起到临时存储框胶的作用，从而可以防止当框胶过多时，框胶溢流进入显示区。进而避免因框胶遮挡显示画面像素造成的显示不良现象的发生。
需要说明的是，辅助导流槽106垂直于引流槽101。辅助导流槽106的宽度W6为0.04毫米至0.2毫米。具体地，辅助导流槽106的宽度W6为0.04毫米、0.06毫米、0.08毫米、0.11毫米、0.14毫米、0.17毫米或0.2毫秒。辅助导流槽106的具体宽度W6由显示模组的中框100的工艺需求所确定。
在本申请实施例提供的中框中，中框包括贴合面、外侧面和内侧面。贴合面上设置有引流槽。外侧面上设置有导流槽和储胶槽。导流槽的一端与引流槽连通。导流槽的另一端与储胶槽连接。引流槽的宽度小于导流槽的宽度。导流槽的宽度小于储胶槽的宽度。当框胶点在贴合面后，框胶会由贴合面流入引流槽、导流槽和储胶槽中。当显示面板贴合时，储存在引流槽、导流槽和储胶槽中的框胶就会反向流入并填满显示面板与中框间的缝隙。采用上述设置，可以最大程度上保证贴合面积，保证贴合可靠性，同时也避免了框胶溢流进入显示区，提高了显示面板的良率。
相应的，本申请实施例还提供一种显示装置。该显示装置包括上述所述的中框100。本申请实施例提供的显示装置可以为智能手机、平板电脑、移动电话、视频电话机、电子书阅读器、手提电脑、上网本、工作站、服务器、个人数字助理、便携式媒体播放器、MP3播放器、移动医疗机器、照相机、游戏机、数码相机、车载导航仪、电子广告牌、自动取款机、智能手环、智能手表、虚拟现实设备或可穿戴设备中的至少一个。上述实施例已经对中框100进行了详细描述，因此，本申请实施例中，对中框100不做过多赘述。
在本申请实施例提供的显示装置中，中框包括贴合面、外侧面和内侧面。贴合面上设置有引流槽。外侧面上设置有导流槽和储胶槽。导流槽的一端与引流槽连通。导流槽的另一端与储胶槽连接。引流槽的宽度小于导流槽的宽度。导流槽的宽度小于储胶槽的宽度。当框胶点在贴合面后，框胶会由贴合面流入引流槽、导流槽和储胶槽中。当显示面板贴合时，储存在引流槽、导流槽和储胶槽中的框胶就会反向流入并填满显示面板与中框间的缝隙。采用上述设置，可以最大程度上保证贴合面积，保证贴合可靠性，同时也避免了框胶溢流进入显示区，提高了显示面板的良率。
