Description

一种AMOLED显示面板 【技术领域】
本发明涉及液晶显示领域，特别是涉及一种AMOLED显示面板。
【背景技术】
有机发光二极管(Organic Light Emitting Diode，OLED)显示面板具有自发光、驱动电压低、发光效率高、响应时间短、清晰度与对比度高、近180°视角、使用温度范围宽等诸多优点，而被广泛地应用于智能手机、平板电脑、全彩电视等。
OLED显示面板按照驱动方式可以分为无源矩阵(Passive Matrix，PM)型和有源矩阵(Active Matrix，AM)型两大类，其中，有源矩阵有机发光二极管(AMOLED)技术是柔性显示重点发展方向之一。
为了实现AMOLED显示面板的显示，需要在相应的背板上设置栅极驱动电路。传统的显示面板是将集成了栅极驱动电路的栅极驱动芯片绑定(Bonding)在有效显示区之外的面板的左右两侧。随着显示技术的发展，出现了代替传统栅极驱动芯片的GOA(Gate Drive On Array)电路，以实现逐行的扫描驱动。但是，现有的显示面板仍然将GOA电路布局于有效显示区之外的面板的左右两侧，不符合显示面板超窄边框的发展趋势。
【发明内容】
本发明主要解决的技术问题是提供一种AMOLED显示面板，能够减少AMOLED显示面板左右边框的宽度。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种AMOLED显示面板，包括GOA电路和有效显示区；其中，GOA电路包括发射GOA模块，发射GOA模块设于有效显示区下方且被有效显示区完全遮盖；其中，GOA电路进一步包括第一扫描GOA模块和第二扫描GOA模块；其中，第一扫描GOA 模块、第二扫描GOA模块与发射GOA模块平行设置，第一扫描GOA模块、第二扫描GOA模块分别设置在有效显示区之外的两侧的边缘区域或设于有效显示区下方且被有效显示区完全遮盖。
为解决上述技术问题，本发明采用的又一个技术方案是：提供一种AMOLED显示面板，包括GOA电路和有效显示区；其中，GOA电路包括发射GOA模块，发射GOA模块设于有效显示区下方且被有效显示区完全遮盖。
本发明的有益效果是：本发明的AMOLED显示面板包括GOA电路和有效显示区；其中，GOA电路包括发射GOA模块，发射GOA模块设于有效显示区下方且被有效显示区完全遮盖。通过上述方式，本发明将发射GOA模块设于有效显示区的下方，有效显示区之外的左右两侧无需设置发射GOA模块，能够显著减少AMOLED显示面板左右边框的宽度，获得窄边框、高PPI(Pixels Per Inch)的显示面板。

在本实施例中，第一驱动信号引脚21提供驱动第一扫描GOA模块11也即多个第一扫描单元111的第一时钟信号XCK1、第二时钟信号CK1和启动信号STV1，其中，第一扫描GOA模块11在第一时钟信号XCK1、第二时钟信号CK1 和启动信号STV1的驱动下产生第一扫描信号Scan1。第二驱动信号引脚22提供驱动第二扫描GOA模块12也即多个第二扫描单元121的第一时钟信号XCK2、第二时钟信号CK2和启动信号STV2，其中，第二扫描GOA模块12在第一时钟信号XCK2、第二时钟信号CK2和启动信号STV2的驱动下产生第二扫描信号Scan2。第三驱动信号引脚23提供驱动发射GOA模块13也即多个发射单元131的第一时钟信号XCK3、第二时钟信号CK3和启动信号STV3，其中，发射GOA模块13在第一时钟信号XCK3、第二时钟信号CK3和启动信号STV3的驱动下产生发射信号EM。
在本实施例中，显示面板100进一步包括驱动像素单元3的电源信号VDD和启动信号VI，其中，启动信号V1用于初始化像素单元3，电源信号VDD用于为像素单元3提供电压。
请一并参考图3，图3是图1所示的AMOLED显示面板的CC区域的示意图。如图3所示，当像素单元3的宽度为x，发射GOA模块13的宽度为y时，在发射GOA模块13上方的有效显示区AA，在平行于发射GOA模块13的宽度的方向上像素单元3的最小重复单元为y/x，其中，y/x大于等于1。也就是说，在发射GOA模块13上，至少设置有一个像素单元3，由于像素单元3能够自发光，从而使得在设置在有效显示区AA下的发射GOA模块13不会影响有效显示区AA的正常发光显示，不会损失显示画质。
在本实施例中，在每行像素单元中，设置在发射GOA模块13上方的像素单元3与相邻的未设置在发射GOA模块13上方的像素单元3共用电源信号VDD，以使得设置在发射GOA模块13上方的像素单元3能够发光。
图4是本发明第二实施例的AMOLED显示面板的结构示意图。图2所示的显示面板200与图1所示的显示面板100的区别在于：第一扫描GOA模块11’、第二扫描GOA模块12’设置于有效显示区AA下方且被有效显示区AA完全遮盖。
在本实施例中，第一扫描GOA模块11’、第二扫描GOA模块12’呈矩形设 置，第一扫描GOA模块11’和第二扫描GOA模块12’沿所述发射GOA模块13的中轴线对称设置。
在本实施例中，第一扫描GOA模块11’、第二扫描GOA模块12’和发射GOA模块13具有相同的长度，第一扫描GOA模块11’、第二扫描GOA模块12’的宽度相同，且小于等于发射GOA模块13的宽度。
在本实施例中，在第一扫描GOA模块11’、第二扫描GOA模块12’上方的有效显示区AA上，至少设置有一个像素单元3，由于像素单元3能够自发光，从而使得在设置在有效显示区AA下的第一扫描GOA模块11’、第二扫描GOA模块12’不会影响有效显示区AA的正常发光显示，不会损失显示画质。
在本实施例中，在每行像素单元中，设置在第一扫描GOA模块11’上方的像素单元3与相邻的未设置在第一扫描GOA模块11’上方的像素单元3共用电源信号VDD，以使得设置在第一扫描GOA模块11’上方的像素单元3能够发光。另外，第二扫描GOA模块12’同理设置。
本领域的技术人员可以理解，在其它实施例中，第一扫描GOA模块11’和第二扫描GOA模块12’也可以不沿发射GOA模块13的中轴线对称设置，例如，第一扫描GOA模块11’靠近发射GOA模块13设置，第二扫描GOA模块12’远离发射GOA模块13设置，从而使得第一扫描GOA模块11’设置于有效显示区AA下方，而第二扫描GOA模块12’设置在有效显示区AA之外的边缘区域。
图5是本发明第三实施例的AMOLED显示面板的结构示意图。图5所示的显示面板300与图4所示的显示面板200的区别在于：显示面板300和有效显示区AA’呈矩形设置，且显示面板300和有效显示区AA’的四个角落位置呈圆角设置。
在本实施例中，在圆角设置的区域，每行像素单元的个数互不相同，且小于显示面板的预定的每行像素单元的个数。其中，预定的每行像素单元的个数也即显示面板的中间区域的每行像素单元的个数。
在本实施例中，由于GOA电路均设置于有效显示区AA’下方且被有效显 示区AA’完全遮盖，因此，有效显示区AA’采用圆角设置时，不用考虑GOA电路圆角设置的问题，更容易实现显示面板的圆角设置。
本发明的有益效果是：本发明的AMOLED显示面板包括GOA电路和有效显示区；其中，GOA电路包括发射GOA模块，发射GOA模块设于有效显示区下方且被有效显示区完全遮盖。通过上述方式，本发明将发射GOA模块设于有效显示区的下方，有效显示区之外的左右两侧无需设置发射GOA模块，能够显著减少AMOLED显示面板左右边框的宽度，获得窄边框、高PPI(Pixels Per Inch)的显示面板。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
