Description

一种显示面板 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。
 背景技术
随着平板显示技术的发展，8K等高分辨率的显示面板已经成为面板行业内的发展趋势。如图1所示，对于COA（Color Filter on Array，在阵列基板上集成彩色滤光片）产品的设计中，位于不同层别的金属层需要通过过孔连接，而过孔需要穿过基板上的色阻层时，为了方便过孔12的打孔制程，形成色阻层后，需要在色阻层上保留一个开口11，过孔位于开口11的中心区域。工程设计中，过孔12和开口11的尺寸以及过孔12的边缘与开口11的边缘之间的距离都需要满足一定要求。
8K等高分辨率的显示面板中的像素大小远远小于4K分辨率的显示面板中的像素大小，因此对于像素的设计更为困难。如图2所示，由于8K等高分辨率的显示面板中像素相对较小，为了满足过孔12和开口11的尺寸要求，只能把开口11设计在色阻边缘。
然而，由于A区13比较靠近透光区，并且形成开口11时由于A区13处的色阻会发生流动和剥离，会导致A区13处产生向透光区方向靠近的弧度，影响透光区的显示效果。

具体的，所述补偿块38包括靠近所述间隙区32设置的第三侧面383，所述第三侧面383与所述色阻块31靠近所述间隙区32的侧面齐平，从而防止补偿块38凸出到间隙区32处影响其他部件的设置。
需要说明的是，补偿块38的宽度，即第三侧面383与增距面384之间的间距可以由像素的实际制成材料和像素的实际尺寸进行设计，以保证补偿块38起到良好的防护作用，同时保证过孔区37与补偿块38之间的距离满足设计需求。
需要说明的是，实际实施中，增距面384的相对的两边缘也可以分别与所述第三侧面383和所述第一侧壁361连接，此时补偿块38的纵截面的整体形状呈三角形。

具体的，所述补偿块38还包括远离所述间隙区32设置的第二侧面382，所述增距面384的相对的两边缘分别与所述第一侧面381和所述第二侧面382连接。
进一步的，所述第二侧面382所在的平面与所述第一侧壁361所在的平面相互垂直，以进一步避免形成开孔36的过程中第一侧壁361形成向透光区33靠近的弧度。

需要说明的是，第一顶角364和第二顶角365为开孔36的两个相邻的拐角，通过在开孔36远离间隙区32的拐角处设置补偿孔35，在对色阻块31采用镭射切割或蚀刻等方式形成开孔36时，残留的色阻材料可以流入到补偿孔35中以填充补偿孔35，从而使得制备得到的开孔36远离间隙区32的拐角处呈直角或接近直角，从而使得实做开孔36的拐角处的图案更接近设计值。
在一实施方式中，所述第一顶角364靠近所述透光区33设置，此时可仅在所述第一顶角364处设置补偿孔35，保证第一顶角364处实做图案更接近设计值，同时可以防止残留的色阻材料向透光区33流动。

需要说明的是，补偿孔35的整体形状可以呈梯形、扇形或方形等，也可根据实际情况对补偿孔35的形状进行选择，例如，在残留的色阻材料较多且补偿孔35的边侧长度确定的情况下，可以选择将补偿孔35的形状设计为面积更大的扇形。
需要说明的是，所述补偿孔35的尺寸也可以根据具体补偿效果进行调整，一般而言，补偿孔35的尺寸与开孔36的尺寸成正比，即开孔36的尺寸越大，补偿孔35的尺寸也越大。
如图12所示，需要说明的是，所述第一侧壁361与所述补偿块38之间的拐角处也可以设置有补偿孔35，防止处于流动状态的残留色阻材料向透光区33方向流动，防止第一侧壁361形成向靠近透光区33方向的弧度影响透光区33的显示效果，同时可以使第一侧壁361与所述补偿块38之间的拐角处为直角或接近直角。
