Description
本申请涉及显示技术领域,尤其涉及一种显示面板的加工方法以及显示面板。
目前,TFT-LCD(Thin Film
Transistor-Liquid Crystal Display)薄膜液晶显示器主要采用每一个像素由一个TFT(Thin Film Transistor)开关控制,TFT开关的栅极连在一起组成栅线,源极层连在一起组成信号线。当在TFT的栅极层G(Gate)上施加电压时,可使TFT进入导通状态,同时显示数据通过信号线、导通的TFT到达TFT的漏极层D(Drain)上,在像素上形成电场并对液晶充电实现显示效果。
理想TFT-LCD显示器的TFT的开态电流越大越好,关态电流越小越好。为了防止背光照射引起漏电流增大,目前TFT-LCD都采用底栅结构以防止背光直接照射到沟道引起漏电流增大。但是底栅结构的栅极与源/漏极层电容较大,过大的寄生电容不仅会导致像素电压的误写入,而且还会加重阈值电压Vth(Threshold voltage)的漂移,严重的Vth漂移又会导致残影的出现。
本申请的目的在于提供一种显示面板的加工方法,旨在解决如何降低栅极层两侧的寄生电容的问题。
本申请是这样实现的,一种显示面板的加工方法,包括下列步骤:
准备基板;
在所述基板上形成第一金属层;
在所述第一金属层的侧部形成附着于所述基板上的所述遮光层;
在所述第一金属层、所述遮光层和所述基板上形成绝缘层,所述第一金属层和所述遮光层均位于所述绝缘层和所述基板之间;
在所述绝缘层上形成半导体层;
在所述半导体层上形成第二金属层,所述半导体层位于所述绝缘层与所述第二金属层之间;
对所述第二金属层和所述半导体层进行加工,以形成沟道,所述沟道将所述第二金属层分隔成源极层和漏极层;
在所述源极层、所述漏极层以及所述沟道的内壁上形成所述保护层;
在所述保护层上形成导电层,使所述导电层连接所述源极层或漏极层。
本申请还提供了一种显示面板,所述显示面板是由如上所述的显示面板的加工方法所制作而成。
本申请在第一金属层两侧涂布遮光层。遮光层不仅能够有效遮光,防止或减少漏电流的产生;而且由于其能够替代一部分栅极进行遮光,进而可以使栅极的宽度设置的更小,同时遮光层具有绝缘属性,因而能够降低栅极和源漏电极的寄生电容,避免过高的寄生电容所引起的像素电压的误写入。同时可以减小Vth在偏置电压作用下的漂移,降低影像残留出现的几率。
