Description

显示面板和显示面板的制造方法 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一种显示面板的制造方法。
背景技术
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，主要包括液晶显示器、OLED(Organic Light-Emitting Diode)显示器、QLED(Quantum Dot Light Emitting Diodes)显示器、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(Backlight Module)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。
而随着用户对于画面要求的不断提高，单纯的RGB(红绿蓝)彩膜工艺已经无法满足用户的需求，因而如何进一步的提高显示面板的显示效果成为本领域技术人员亟待解决的问题。
