Description

显示面板和显示装置
本申请要求于2019年01月18日提交中国专利局，申请号为CN201910046320.3，申请名称为“一种显示面板和显示装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及显示技术领域，尤其涉及一种显示面板和显示装置。
背景技术
这里的陈述仅提供与本申请有关的背景信息，而不必然地构成现有技术。
液晶显示面板(Liquid Crystal Display，LCD)具有功耗低、色域广、大视角等优点，是市场上最主流的显示器。液晶显示面板主要包括阵列基板(Thin Film Transistor，TFT)、彩膜基板(Color filter，CF)、以及夹在两基板之间的液晶层，在对盒组装(Cell)制程中，会在两基板的四周涂布框胶并于框胶内注入液晶层，将框胶进行固化后得到一液晶显示面板结构。通过TFT基板对画素充放电控制液晶的偏转，从而实现不同的显示画面。
当框胶涂布时会导致框胶无法完全贴合在基板表面，容易引起外界空气进入液晶层，腐蚀线路或产生气泡。
发明内容
本申请的目的是提供了一种显示面板和显示装置，易于框胶贴合。
为实现上述目的，本申请公开了一种显示面板，包括基板、第一金属层、第一绝缘层、第二金属层、第二绝缘层和框胶，其中基板分为显示区和非显示区，所述非显示区围绕所述显示区；第一金属层设置在所述基板上，位于所述非显示区内；第一绝缘层设置在所述第一金属层和所述基板上；第二金属层设置在所述第一绝缘层上，并位于所述非显示区内；第二绝缘层设置在所述第二金属层和所述第一绝缘层上，覆盖所述第一金属层和所述第二金属层；框胶设置在所述第二绝缘层上，对应所述第一金属层与所述第二金属层，所述第一金属层和所述第二金属层在垂直于所述基板的方向上错位。
本申请还公开了一种显示面板，包括：基板、第一金属层、第一绝缘层、第二金属层、第二绝缘层、框胶、多个第一驱动电路和多个第二驱动电路；所述基板分为显示区和非显示区，所述非显示区围绕所述显示区；所述第一金属层设置在所述基板上，位于所述非显示区 内；所述第一绝缘层设置在所述第一金属层和所述基板上；所述第二金属层设置在所述第一绝缘层上，位于所述非显示区内；所述第二绝缘层设置在所述第二金属层和所述第一绝缘层上，覆盖所述第一金属层和所述第二金属层；所述框胶设置在所述第二绝缘层上；所述多个第一驱动电路驱动设置在所述显示区的扫描线；以及所述多个第二驱动电路驱动设置在所述显示区的数据线；其中，所述第一金属层和所述第二金属层沿同一方向排布，所述第一金属层和所述第二金属层连接相邻的两个所述第一驱动电路，或连接相邻的两个所述第二驱动电路，所述第一金属层包括多条第一金属线，所述第二金属层包括多条第二金属线，相同排布方向的所述第一金属线和所述第二金属线在垂直于所述基板方向上的投影无重合，沿同一方向排布的每两条相邻所述第一金属线和所述第二金属线在垂直于所述基板方向上投影的间距相等，所述框胶垂直于所述基板方向上的投影与所述第一金属线和所述第二金属线垂直于所述基板方向上的投影至少部分重合；
所述第一金属线包括多条第一金属第一线和多条第一金属第二线，所述第二金属线包括多条第二金属第一线和多条第二金属第二线，所述多条第一金属第一线和所述多条第二金属第一线沿同一方向排布，所述多条第一金属第二线和所述多条第二金属第二线沿同一方向排布，所述多条第一金属第一线与所述多条第一金属第二线的排布方向不一致；所述多条第一金属第一线与所述多条第二金属第一线在垂直于所述基板方向上的投影无重合，所述多条第一金属第二线与所述多条第二金属第二线在垂直于所述基板方向上的投影无重合，所述多条第一金属第一线与所述多条第一金属第二线在垂直于所述基板方向上垂直设置，所述多条第二金属第二线与所述多条第二金属第二线在垂直于所述基板方向上垂直设置；至少部分位于所述第一金属层上的所述第二绝缘层的上表面的高度，与至少部分位于所述第二金属层上的所述第二绝缘层的上表面的高度相等。
本申请还公开了一种显示装置，包括显示面板，所述显示面板包括基板、第一金属层、第一绝缘层、第二金属层、第二绝缘层以及框胶；所述基板分为显示区和非显示区，所述非显示区围绕所述显示区；所述第一金属层设置在所述基板上，位于所述非显示区内；所述第一绝缘层设置在所述第一金属层和所述基板上；所述第二金属层设置在所述第一绝缘层上，位于所述非显示区内；所述第二绝缘层设置在所述第二金属层和所述第一绝缘层上，覆盖所述第一金属层和所述第二金属层；以及所述框胶设置在所述第二绝缘层上，对应所述第一金属层与所述第二金属层；其中，所述第一金属层和所述第二金属层在垂直于所述基板的方向上错位。
相对于第一金属层和第二金属层在垂直于所述基板方向上完全重叠的方案来说，本申请第一金属层和第二金属层在垂直于所述基板的方向上错位，由于第二绝缘层是覆盖第一金属层和第二金属层的，框胶又是设置在第二绝缘层上并对应着第一金属层和第二金属层的，这 样就降低了第二绝缘层对应金属层部分的表面在垂直于所述基板方向上的段差，令第二绝缘层的表面更加平坦，这部分的第二绝缘层与框胶接触的部分斜率更低，给予框胶的支撑力会更大，使框胶更好的贴附在第二绝缘层上，减少框胶与第二绝缘层之间的缝隙，从而降低外界空气或水汽穿过框胶进入到显示面板内，防止基板内产生气泡或部件受腐蚀。

下面参考附图和可选的实施例对本申请作进一步说明。
液晶层是通过框胶密封在基板内部防止外泄。通常对于液晶面板来说，不能有空气或者水汽进入液晶层，否则容易引起显示面板内产生气泡，或者导致阵列基板侧的电路腐蚀令画面显示异常。当框胶涂布在高低不平的基板表面时，会导致框胶无法完全贴合在基板表面，框胶与基板的贴合处会有一定的狭缝，容易引起外界空气沿着框胶与基板表面之间的缝隙进入液晶层，图1至图3为一种未公开的示例性显示面板，显示面板包括显示区220和非显示区230，非显示区内230设有外围走线231和胶框280，外围走线231和胶框280部分重合。外围走线231包括第一金属层240和第二金属层260，第一金属层240和第二金属层260是堆叠在一起的，第二绝缘层270表面的段差H较高，框胶280与第二绝缘层270在段差H处表面的贴合效果就不好，容易产生狭缝。
下面参考附图和可选的实施例对本申请作说明。
如图4至图10所示，本申请实施例公开了一种显示面板，包括基板210、第一金属层240、第一绝缘层250、第二金属层260、第二绝缘层270和框胶280，其中基板210分为显示区220和非显示区230，显示区220被配置为显示画面，非显示区230围绕显示区220；第一金属层240设置在基板210上，位于非显示区230内；第一绝缘层250设置在第一金属层240和基板210上；第二金属层260设置在第一绝缘层250上，位于非显示区230内；第 二绝缘层270设置在第二金属层260和第一绝缘层250上，覆盖第一金属层240和第二金属层260；框胶280设置在第二绝缘层270上；对应第一金属层240与第二金属层260；第一金属层240和第二金属层260在垂直于基板210的方向上错位。
第一金属层240和第二金属层260在垂直于基板210的方向上错位，由于第二绝缘层270是覆盖第一金属层240和第二金属层260的，框胶280又是设置在第二绝缘层270上并对应着第一金属层240和第二金属层260的，错位能降低第二绝缘层270对应金属层部分的表面在垂直于基板210方向上的段差，令第二绝缘层270的表面更加平坦，这部分的第二绝缘层270与框胶280接触的部分斜率更低，给予框胶280的支撑力会更大，使框胶280更好的贴附在第二绝缘层270上，减少框胶280与第二绝缘层270之间的缝隙，从而降低外界空气或水汽穿过框胶280进入到显示面板内，防止基板210内产生气泡或部件受腐蚀。
第一金属层240包括多条第一金属线241，第二金属层260包括多条第二金属线261，相同排布方向的第一金属线241和第二金属线261在垂直于基板方向上的投影无重合，即第一金属线241和第二金属线261各包括沿不同方向排列的走线，但只要是在一个方向上排布的第一金属线241和第二金属线261要在垂直于所述基板的方向上不重叠。框胶280垂直于基板方向上的投影与第一金属线241和第二金属线261垂直于基板方向上的投影至少部分重合。
显示面板包括相对设置的阵列基板210和彩膜基板210，第一金属层240和第二金属层260设置在阵列基板210的非显示区230内，框胶280位于第一金属线241和第二金属线261之上并围绕着显示区220将阵列基板210和彩膜基板210密封，由于框胶280涂布后需要通过紫外光来固化框胶280，而紫外光一般是通过阵列基板210一侧照射，第一金属层240和第二金属层260对光线具有遮蔽的作用，光线很难透过第一金属层240或第二金属层260，所以将第一金属层240和第二金属层260中间镂空，形成多条第一金属线241和多条第二金属线261以使光线透过第一和第二金属线261之间的空隙，相同排布方向的第一金属线241和第二金属线261在垂直于基板方向上的投影无重合，令沿同一方向排布的第一金属线241和第二金属线261互相错位，由于第二绝缘层270是覆盖第一金属层240和第二金属层260的，降低了第二绝缘层270表面之间在垂直于基板方向上的段差H，令第二绝缘层270的表面更加平坦，使框胶280更好的贴附在第二绝缘层270上，减少框胶280与第二绝缘层270之间的缝隙，从而降低外界空气或水汽穿过框胶280进入到显示面板内，防止基板210内产生气泡或部件受腐蚀。
框胶280的材质由环氧树脂、固化剂、填料和其他助剂所配置，框胶280未经紫外光固化之前具有一定流动性，但是不同于一般的流体如水，框胶280具有一定的黏性，如果框胶280涂布在段差H较高的表面，会因为段差H处框胶280的自身重力无法克服自身黏性而 部分停留在段差H处的侧壁无法向下流动，而段差H低的表面斜率也相对较低，框胶280对段差H表面的压力也会增加，有利于框胶280继续向下流，减少框胶280与第二绝缘层270之间的缝隙。第一金属层240和第二金属层260在水平方向上的投影无重合，第一金属层240和第二金属层260为两层金属，第一金属层240和第二金属层260的首末两端通过过孔连在一起。
如图4所示，数据线2110和扫描线2100位于显示区220内，第一金属层240、第二金属层260、第一驱动电路290、第二驱动电路291和时序控制器300位于非显示区230内，多个第一驱动电路290以驱动扫描线2100，多个第二驱动电路291以驱动数据线2110；第一金属层240和第二金属层260连接相邻的两个第一驱动电路290，或连接相邻的两个第二驱动电路291；
第一金属层240和第二金属层260也可以分别连接时序控制器300和第一驱动电路290、第二驱动电路291，为时序控制器300传输信号，或者是与相邻第一驱动电路290和相邻第二驱动电路291相连，传输信号，第一金属层240和第二金属层260为同一种走线，两层金属层的分布间接的增大了电流通过路径的横截面积，降低了走线阻值。
如图5和图6所示，第二金属线261在第一金属线241之上，在垂直于基板方向上的位置互相交错，第一金属线241包括多条第一金属第一线242和多条第一金属第二线243，第二金属线261包括多条第二金属第一线262和多条第二金属第二线263，多条第一金属第一线242和多条第二金属第一线262的排布方向一致，多条第一金属第二线243和多条第二金属第二线263的排布方向一致，多条第一金属第一线242与多条第一金属第二线263的排布方向不一致。
第一金属第一线262的排布方向与框胶280的涂布方向一致，第一金属层240和第二金属层260的电流方向与第一金属第一线242的排布方向一致，第一金属线241和第二金属线261各种方向的走线排布构成了网状的镂空区域，镂空区域便于紫外光透过第一金属层240和第二金属层260来固化框胶280，从而提高框胶280固化的时间和效果，而与电流方向排布不一致的走线可以防止第一金属线241或第二金属线261局部断路而引发无法传输信号或阻值提高，例如，第一金属第一线242在某两条第一金属第二线243之间发生断路，一般情况下第一金属第一线242因为断路就不会有电流通过，从而第一金属第一线242无法传输信号以及第一金属层240的阻值升高增加功耗，而有了连接各种和电流方向一致的走线后，第一金属第一线242的电流便能通过断点附近的第一金属第二线243传输到相邻的另一条第一金属第一线242上，电流再经过下一条第一金属第二线243后还能再流到之前有断点的那条第一金属第一线242上，从而为线路提供多重保障。
第一金属第二线243和第二金属第二线263与第一金属第一线242和第二金属第一线 262的排布方向垂直。第一金属第二线243和第二金属第二线263都是将与电流排布方向一致的线路所连接，为第一金属层240和第二金属层260线路故障提供多重保障，第一金属第二线243和第二金属第二线263长度越短越好，一方面为了减少流经的电流所受电阻，一方面还可以减少占用空间，相应的提高第一金属层240和第二金属层260的镂空面积，提高固化框胶280的速度，另一方面还能为第一金属层240和第二金属层260提供较大的抗拉强度，防止错位以及断线。
如图6所示，至少部分位于第一金属层上的第二绝缘层270的上表面的高度d，与至少部分位于所述第二金属层上的第二绝缘层270的上表面的高度d相等。由于第一金属层与第二金属层交错排布，那么第一金属层与第二金属层在垂直于基板方向上的高度不一定一致，所以要保证覆盖在它们上面的第二绝缘层270的高度d相等，令涂布框胶280的接触表面更平整，利于框胶280与第二绝缘层270的接触更紧密。
在一实施例中，多条第一金属第一线242与多条第二金属第一线263在垂直于基板方向上的投影无重合，多条第一金属第二线243与多条第二金属第二线263在垂直于基板方向上的投影无重合。
第二绝缘层270是设置在第二金属线261和第一绝缘层250上的，覆盖第一金属线241和第二金属线261，第一金属线241和第二金属线261都有一定的厚度，要尽量避免第一金属线241与第二金属线261之间有重合的部分，这样覆盖在第一金属线241和第二金属线261上的第二绝缘层270也会更平坦，框胶280与第二绝缘层270接触的地方也就更平坦，提高框胶280的贴附能力，使框胶280更好的贴附在第二绝缘层270上，减少框胶280与第二绝缘层270之间的缝隙，提高基板210的密封性。
如图5所示，间距d为在垂直于基板方向上，同方向排布的相邻走线之间的距离，沿同一方向排布的第一金属线241与相邻的两条第二金属线261的间距d相等。
相同排布方向的相邻第一金属线241和第二金属线261在垂直于基板方向上投影的间距d相等，保证了第一金属线241和第二金属线261之间每个镂空区域的大小都相等，使每个镂空区域透过紫外光的面积都一样，从而使框胶280整体固化的速度更均匀，减少了紫外光固化的时间。当然，间距不等也是可行的。可选的，沿同一方向排布的第一金属线241与相邻第二金属线261在垂直于基板方向上投影的间距d大于等于3微米。
第一金属线241和第二金属线261都是通过对第一金属层240和第二金属层260蚀刻形成的，而在蚀刻前需要对第一金属层240和第二金属层260上的光刻胶进行曝光显影形成需要的图案，在将图案外的金属层蚀刻掉形成所需的第一金属线241和第二金属线261，由于曝光机机台位移精度及曝光精度限制，沿同一方向排布的第一金属线241与相邻第二金属线261的在垂直于基板方向上投影的间距不能为零，如果没有间距会存在曝光精度不足，导致 相邻的第一金属线241和第二金属线261存在一定部分的交叠，从而交叠这部分的第二绝缘层270段差H较高，影响框胶280的贴附效果。
如图7所示，沿同一方向排布的第一金属线241与相邻第二金属线261在垂直于基板方向上投影的间距为3微米。
由于框胶280涂布后需要通过紫外光来固化框胶280，而紫外光一般是通过阵列基板210一侧照射，紫外光要穿过沿同一方向排布的每两条相邻第一金属线241和第二金属线261在垂直于基板方向上形成的镂空区域，从而照射到框胶280实现框胶280的固化，在保证曝光精度的同时使第一金属层240和第二金属层260在垂直于基板方向上的单个镂空面积最大，形成局部较大的镂空区域，透过更多的紫外光，使得位于镂空区域的框胶280固化很快，又由于这种镂空区域的分布较多以及较平均，固化快的框胶280能阻止固化慢的框胶280外流，整体了减少框胶280的溢出。
如图8至图10所示，第二金属层260在第一金属层240的上面，在垂直于基板方向上第二金属层260和第一金属层240局部交错，第二金属层260的两侧与第一金属层240的两侧相重叠，第一金属层240包括两条外围第一金属线244，对应设置在第一金属层240的两侧；第二金属层260包括两条外围第二金属线264，对应设置在第二金属层260的两侧；框胶280与外围第一金属线244和外围第二金属线264在垂直于基板方向上的投影不重合，外围第一金属线244与外围第二金属线264在垂直于基板方向上的投影互相重合，框胶280位于两组外围第一金属线244之间。
外围第一金属线244和外围第二金属线264的排布方向是与框胶280的涂布方向一致的，外围第一金属线244和外围第二金属线264位于第一金属层240和第二金属层260的边缘，在固化框胶280之前框胶280为流体，具有流动性，在涂布框胶280时框胶280具有向外围扩散的趋势，为减少这种扩散趋势，将外围第一金属线244和外围第二金属线264在垂直于基板方向上重合，重合的这部分高度相对其它部分较高，而覆盖在重合部分上的第二绝缘层270也就具有较高的段差H，这部分较高的段差H对未固化的框胶280外溢有一定阻挡作用。
如图11所示，作为本申请的另一实施例，公开了一种显示装置100，包括上述实施例任意显示面板。
本申请的技术方案可以广泛应用在各种显示面板中，如扭曲向列型(Twisted Nematic，TN)显示面板、平面转换型(In-Plane Switching，IPS)显示面板、垂直配向型(Vertical Alignment，VA)显示面板、多象限垂直配向型(Multi-Domain Vertical Alignment，MVA)显示面板，当然，也可以是其他类型的显示面板，如有机发光二极管(Organic Light-Emitting Diode，OLED)显示面板，均可适用上述方案。
以上内容是结合具体的可选的实施方式对本申请所作的详细说明，不能认定本申请的具体实施只局限于这些说明。对于本申请所属技术领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本申请的保护范围。
