Description

显示面板、显示模组及制作方法Display panel, display module and manufacturing method 技术领域Technical field
本申请涉及显示领域，尤其涉及一种显示面板、显示模组及制作方法。This application relates to the field of display, and in particular to a display panel, a display module and a manufacturing method.
背景技术Background technique
阵列栅极驱动（Gate Driver On Array，GOA）就是利用现有薄膜晶体管液晶显示器中的阵列制程将栅极行扫描驱动信号电路制作在阵列基板上，实现对栅极逐行扫描的驱动方式。Gate Driver On Array (Gate Driver On Array, GOA) is to use the existing thin-film transistor liquid crystal display array manufacturing process to fabricate the gate row scan driving signal circuit on the array substrate to realize the driving method of the gate progressive scan.
在GOA电路中，位于非显示区域的Gate走线为M2走线（源漏极层），位于显示区域的Gate走线为M1走线（栅极层）。因此，现有GOA电路中非显示区域的Gate走线需要经过过孔换线至与显示区域的Gate走线同层的金属线。而由于靠近显示区域的过孔周边为地势低点，因此在形成过孔时容易导致显示区域中的膜层材料向该过孔周边堆积，影响产品的品质。In the GOA circuit, the gate traces located in the non-display area are M2 traces (source-drain layer), and the gate traces located in the display area are M1 traces (gate layer). Therefore, the gate traces in the non-display area in the existing GOA circuit need to pass through vias to be changed to the metal lines on the same layer as the gate traces in the display area. However, since the periphery of the via hole close to the display area is a low point of terrain, when the via hole is formed, the film material in the display area is likely to accumulate to the periphery of the via hole, which affects the quality of the product.
因此，目前亟需一种显示面板以解决上述问题。Therefore, there is an urgent need for a display panel to solve the above-mentioned problems.
