Description

OLED显示模组及该显示模组的制备方法
【技术领域】
本发明涉及显示技术领域，特别涉及一种OLED显示模组及该显示模组的制备方法。
【背景技术】
随着科技的发展，电子设备变得越来越常见。现在的电子设备除了有显示屏外，还设置有驱动芯片和/或柔性电路板。
图1是现有技术中显示模组正面的结构示意图，图2是现有技术中显示模组背面的结构示意图。显示屏10正面会在有效显示区域11下方留下很大一部分的下边界（border）区域12，用于放置驱动芯片13与柔性电路板14，以向显示信号输入端15提供驱动信号，驱动芯片13通过本身的输入焊盘（Input pad）、输出焊盘（output pad）与显示屏上的焊盘(ITO pad)相互贴合。
请参阅图3，图3是现有技术中驱动芯片13与显示屏10贴合面的结构示意图，驱动芯片13的信号输出引脚131位于驱动芯片13的第一端，信号输入引脚132位于驱动芯片13的第二端。该第一端与第二端为驱动芯片13长度方向上相对的两个端部。
随着显示屏分辨率的提高，驱动芯片本身的输入焊盘、输出焊盘以及显示屏上的焊盘、数据走线(source line)变得越来越多。当下边界区域12面积一定时，分辨率越高，驱动芯片上的焊盘与显示屏上的焊盘越小，数据走线更加密集。焊盘的缩小以及数据走线的密集必然会导致显示模组设计难度的增加以及显示模组产出良率的降低。
有机发光二极管显示屏（Organic Light Emitting Diode,以下简称为OLED）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、可实现柔性显示与大面积全色显示等诸多优点，且相对于现有液晶显示屏，OLED显示屏正反面无导光板隔离。
鉴于OLED的以上特性，有必要设计一种新的、设计难度相对较低的OLED显示模组。
