Description

一种显示终端及应用于显示终端中的显示面板 技术领域
本申请涉及显示技术领域，尤其涉及一种显示终端及应用于显示终端中的显示面板。
 背景技术
随着显示技术的迅猛发展，具有显示功能的终端产品逐渐朝着可折叠、全面屏、轻薄化的方向发展。由于有机发光二极管(Organic Light-Emitting Diode，OLED)显示器件具有自发光、对比度高、厚度薄、广视角和响应速度快等优点，所以成为新一代平面显示技术的代表，并逐渐被引入至柔性显示技术领域中，但是目前，柔性OLED显示技术还不够成熟，仍有许多需要完善和优化之处。
目前，如图1和图2所示，柔性OLED显示面板包括承载基板1，承载基板1上划分有显示区2和非显示区3，所述非显示区3设置于所述显示区2的周围，其中，显示区域2由相连的第一显示子区21和第二显示子区22组成，非显示区3由依次相连的第一非显示子区31、第二非显示子区32、第三非显示子区33和第四非显示子区34组成，柔性OLED显示面板可向M/N方向折叠，其中，各个非显示子区域的宽度W至少有1.0毫米。当然，所述柔性OLED显示面板也可向与M/N方向相垂直的水平方向折叠，对应所述第一显示子区域21和所述第二显示子区域22的位置发生适应性调整，在此不再赘述。
 技术问题
在现有技术中，上述柔性OLED显示面板应用于终端产品的方式有三种。第一种应用方式如图3所示，柔性OLED显示面板的折叠部位设置于右侧，折叠后，显示区域2和非显示区域3位于外侧，基板1位于内侧，并且位于折叠部位两侧的部分为不对称设计，柔性OLED显示面板可随终端产品动态折叠。第二种应用方式如图4所示，柔性OLED显示面板的折叠部位设置于右侧，折叠后，显示区域2和非显示区域3位于内侧，基板1位于外侧，并且位于折叠部位两侧的部分为对称设计，柔性OLED显示面板可随终端产品动态折叠。第三种应用方式如图5所示，柔性OLED显示面板具有两个折叠部位，分别设置于左侧和右侧，折叠后，显示区域2和非显示区域3位于外侧，基板1位于内侧，柔性OLED显示面板为静态折叠。
对于第一种应用方式和第二种应用方式，柔性OLED显示面板在展平状态下为大尺寸屏幕，具有难实现极窄边框、非显示区域宽度大的缺点，并且在现有技术下缩减非显示区域宽度的难度较大，此外，第一种应用方式和第二种应用方式中的左侧区域的屏占比存在优化空间。在第三种应用方式中，图5中的空缺处100存在优化空间。
