Description

一种显示面板和显示装置
本申请要求于2018年5月21日提交中国专利局、申请号为：2018104921225、申请名称为“一种显示面板和显示装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及显示技术领域，尤其涉及一种显示面板和显示装置。
背景技术
这里的陈述仅提供与本申请有关的背景信息，而不必然地构成现有技术。
显示器一般都基于主动开关进行控制，具有机身薄、省电、无辐射等众多优点，得到了广泛的应用，主要包括OLED(Organic Light-Emitting Diode)显示器、液晶显示器、QLED(Quantum Dot Light Emitting Diodes)显示器以及等离子显示器等，从外观结构来看，既有平面型显示器，也有曲面型显示器。对于液晶显示器，包括液晶面板及背光模组两大部分，液晶显示器的工作原理是在两片平行的玻璃基板当中放置液晶分子，并在两片玻璃基板上施加驱动电压来控制液晶分子的旋转方向，以将背光模组的光线折射出来产生画面。对于OLED显示器，采用机发光二极管自发光来进行显示，具有自发光、广视角、几乎无穷高的对比度、较低耗电以及极高反应速度等优点。QLED显示器结构与OLED技术非常相似，主要区别在于，QLED的发光中心由量子点物质构成，其结构是两侧电子和空穴在量子点层中汇聚后形成光子，并且通过光子的重组发光。
在薄膜晶体管液晶显示器(thin film transistor-liquid crystal display，TFT-LCD)面板制造过程中，盒厚的设计与控制是液晶显示器的关键技术之一，直接影响了显示器的品质，液晶层厚度主要通过彩膜基板与阵列基板之间的间隙子(Photo Spacer，PS)来控制，由于间隙子的高度在整个显示面板上均相等，容易造成显示面板液晶盒厚的均匀性发生变化，影响显示面板的显示效果。
