Description

显示装置
技术领域
本发明涉及显示技术领域，尤其涉及一种显示装置。
背景技术
在显示技术领域，液晶显示装置(Liquid Crystal Display，LCD)等平板显示装置已经逐步取代阴极射线管(Cathode Ray Tube，CRT)显示装置。液晶显示装置具有机身薄、省电、无辐射等众多优点，得到了广泛的应用。
现有市场上的液晶显示装置大部分为背光型液晶显示装置，其包括液晶显示面板及背光模组(backlight module)。通常液晶显示面板由彩膜(Color Filter，CF)基板、薄膜晶体管(Thin Film Transistor，TFT)阵列基板、夹于彩膜基板与薄膜晶体管阵列基板之间的液晶(Liquid Crystal，LC)及密封胶框(Sealant)组成。液晶显示面板的工作原理是在两片平行的玻璃基板当中放置液晶分子，两片玻璃基板中间有许多垂直和水平的细小电线，通过通电与否来控制液晶分子改变方向，将背光模组的光线折射出来产生画面。
随着显示技术的发展，越来越多的应用功能场景下需要更大显示面积的显示装置，传统的具有单块显示面板的显示装置无法满足该要求，由多块显示面板拼接而成的显示装置由此产生。请参阅图1，为现有的一种由两块显示面板拼接而成的显示装置的结构示意图，该显示装置包括间隔设置的两块液晶显示面板100、设于该两块液晶显示面板100之间以及该两块液晶显示面板100外侧的黑矩阵(black matrix，BM)边框200。该显示装置在进行显示时，两块液晶显示面板100能够进行显示，但黑矩阵边框200却无法进行显示，这导致该显示装置的显示的画面中会出现对应黑矩阵边框200的黑线，影响显示的效果，产品的品质较差。
OLED(Organic Light-Emitting Diode，有机发光二极管)显示器是一种新型的平板显示装置，由于其具有可进行自发光、制备工艺简单、成本低、功耗低、发光亮度高、工作温度适应范围广、体积轻薄、响应速度快、易于实现彩色显示和大屏显示、易于实现和集成电路驱动器向匹配、易于实现柔性显示等优点，具有广阔的应用前景。
迷你发光二极管(mini LED)显示装置是一种在一个基板上集成微小尺寸的LED阵列作为显示像素来实现图像显示的显示装置，其每一个像素均可定址、单独驱动点亮，属于自发光显示器，其耗电量小，且色彩饱和度接近OLED，很多厂商将其作为目前的研究重点。
