随着显示屏技术的不断发展，显示屏的集成度越来越高。为减少组成显示屏的子零部件受到供应链的风险以及对应成本把控的考量，通常，组装显示屏的厂家对于一些重要的子零部件会选择多家供应商为其供货，而不同供应商的设计、工艺可能存在差异，使得品牌二元化成为一种制约性的因素。例如，显示屏中的驱动芯片(Drive IC,DIC)和电源管理芯片(Power Management IC,PMIC)，由于不同厂家的设计、工艺等因素，生产的电源管理芯片和驱动芯片的大小、软件驱动程序可能存在差异，而容易导致不同厂家生产的电源管理芯片和驱动芯片之间无法兼容。
请参阅图1，有鉴于此，本申请提供了一种显示模组10，显示模组10包括驱动芯片11和电源管理芯片12，电源管理芯片12包括第一标识引脚121，第一标识引脚121与驱动芯片11连接；
在电源管理芯片12开启的情况下，电源管理芯片12通过第一标识引脚121向驱动芯片11发送标识信息以使得驱动芯片11识别电源管理芯片12并与电源管理芯片12配对。
在本申请中的显示模组10中，电源管理芯片12通过第一标识引脚121与驱动芯片11相连，从而在电源管理芯片12与驱动芯片11配对时，能够通过第一标识引脚121向驱动芯片11发送对应的标识信息，使得驱动芯片11能够根据标识信息而与驱动芯片11配对。如此，实现了不同厂家生产的驱动芯片11和电源管理芯片12之间能够兼容，降低了供应 链的风险，节省了成本。
显示模组10可以采用有源矩阵有机发光二极体面板(Active-matrix organic light-emitting diode，AMOLED)进行显示。电源管理芯片12通过驱动芯片11与有源矩阵有机发光二极体面板电性连接。其中，电源管理芯片12用于给有源矩阵有机发光二极体面板供电，驱动芯片11用于驱动有源矩阵有机发光二极体面板进行显示。显示模组10采用有源矩阵有机发光二极体面板进行显示，可以实现自主发光并且能够对像素点实现定制驱动，无需背光灯，即可实现显示功能，并且具有能耗低、视角宽、高刷新率和薄尺寸等特点。
需要说明的是，驱动芯片11和电源管理芯片12都可以是集成电路(Integrated Circuit，IC)芯片，并且，驱动芯片11可通过绑定引脚(Bonding Pin)的方式与电源管理芯片12实现电连接。标识信息是指用于表征电源管理芯片种类或品牌等的一种身份信息。每种电源管理芯片12或每个品牌的电源管理芯片12都包括对应的标识信息，驱动芯片11能够根据标识信息而识别出电源管理芯片12的种类或者品牌等。
具体而言，电源管理芯片12包括有第一标识引脚121，驱动芯片11包括有第二标识引脚112。在电源管理芯片12与驱动芯片11装配时，第一标识引脚121与第二标识引脚112相连。电源管理芯片12包括有对应的标识信息，在电源管理芯片12启动后通过第一标识引脚121向第二标识引脚112发送标识信息，从而在驱动芯片11能够根据标识信息与电源管理芯片12匹配。如此，避免了出现驱动芯片11与电源管理芯片12不兼容的情况。
需要说明的是，标识信息可以在电源管理芯片12设计或出厂时由厂家进行烧录。请结合图2，标识信息可以是脉冲信号，不同种类或品牌等的驱动芯片11的标识信息中脉冲的个数或脉冲的宽度不同。驱动芯片12可根据脉冲信号的脉冲个数、宽度等确定电源管理芯片12的种类或品牌等。在本申请中，驱动芯片11可根据脉冲信号的脉冲个数确定与其连接的电源管理芯片12的种类或品牌。例如，在一些示例中，电源管理芯片A包括标识信息1，标识信息1中脉冲的数量为5个，电源管理芯片B包括标识信息2，标识信息2中脉冲的数量为3个，若电源管理芯片A与驱动芯片11连接，驱动芯片11可根据标识信息中脉冲的数量识别出电源管理芯片A。
在某些实施方式中，驱动芯片11包括使能引脚111，使能引脚111与电源管理芯片12连接，驱动芯片11通过使能引脚111向电源管理芯片12发送使能信号以启动电源管理芯片12。
如此，驱动芯片11可通过使能引脚111向电源管理芯片12发送使能信号，在电源管理芯片12接收到使能信号后能够启动，从而能够将标识信号通过第一标识引脚121发送至第二标识引脚112，使得驱动芯片11能够与电源管理芯片12匹配。
在某些实施方式中，驱动芯片11包括多个存储寄存器113，多个存储寄存器113分别与多个电源管理芯片12对应，每个存储寄存器113存储有与对应的电源管理芯片12配对的查找表(Look Up Table，LUT)。
具体地，每个电源管理芯片12包括有LUT。可以理解，不同厂家的电源管理芯片12中的LUT可能存在差异，而要使得驱动芯片11与电源管理芯片12能够兼容，驱动芯片11的LUT必须要能够与任意的电源管理芯片12的LUT匹配。因此，驱动芯片11通过设置多个存储寄存器113，每个存储寄存器113存储有与对应电源管理芯片12中LUT配对的LUT。从而，在驱动芯片11与电源管理芯片12配对过程中，驱动芯片11可根据标识信息识别出电源管理芯片12后，选择对应存储寄存器113中的LUT与该电源管理芯片12的LUT配对，如此，保证了驱动芯片11与不同的电源管理芯片12兼容。
在某些实施方式中，驱动芯片11还包括控制信号发送引脚114，控制信号发送引脚114与电源管理芯片12连接，驱动芯片11根据电源管理芯片12的标识信息生成控制信号(Swire信号)并通过控制信号发送引脚114向电源管理芯片12发送控制信号。
具体地，电源管理芯片12还包括有对应的控制信号接收引脚122，控制信号接收引脚122与控制信号发送引脚114连接。在驱动芯片11接收到电源管理芯片12的标识信号而与电源管理芯片12配对后，驱动芯片11的LUT可根据标识信号生成控制信号，并由控制信号发送引脚114将控制信号发送至控制信号接收引脚122，如此，电源管理芯片12可根据控制信号执行相应的操作。
在某些实施方式中，电源管理芯片12还包括多个供电引脚123，电源管理芯片12根据控制信号确定各个供电引脚123的电压并通过多个供电引脚123向驱动芯片11供电。

请结合图4，具体地，每个电源管理芯片12中的LUT包括有脉冲个数与供电引脚123的输出电压对应的映射关系。例如，请一并参阅图3和图4，在一些示例中，控制信号中 的连续三段脉冲信号的脉冲个数分别为5个、6个及7个，则在电压管理芯片的LUT中三个供电引脚123的输出电压分别为-5.0V、-4.9V及-4.8V。在电源管理芯片12接收到控制信号后，电源管理芯片12的可根据每段脉冲信号中的脉冲个数而将对应的供电引脚123的电压调节至与LUT中脉冲个数所对应的电压匹配，使得供电引脚123以调节后的输出电压向驱动芯片11供电。
