Title
(EN) Quantum dot color film substrate, preparation method thereof and display panel
(ZH) 量子点彩膜基板及其制备方法、显示面板
Abstract
(EN) The invention provides a quantum dot color film substrate which comprises a substrate body, a color filter layer, a quantum dot film layer and a transparent conducting layer, the transparent conducting layer is arranged between the color filter layer and the quantum dot film layer, and the transparent conducting layer is externally connected to a power module and forms a closed loop with the powermodule. The transparent conducting layer is additionally arranged below the quantum dot film layer, the transparent conducting layer is externally connected to the power module to form the closed loop, in the closed loop, the transparent conducting layer is equivalent to a resistor, and when voltage is applied to the transparent conducting layer, the transparent conducting film layer can generateheat, so that a solvent in the quantum dot film layer can be quickly removed.
(ZH) 一种量子点彩膜基板,包括衬底、彩色滤光层、量子点膜层、以及透明导电层,透明导电膜层设置于所述彩色滤光层与所述量子点膜层之间,透明导电层外接于一电源模块,与电源模块形成闭合回路。通过在量子点膜层下方增设一层透明导电层,并对透明导电层外接于一电源模块以形成闭合回路,在闭合回路中,透明导电层相当于一个电阻,当对透明导电层施加电压时,透明导电膜层会产生热量,从而能够快速去除量子点膜层中的溶剂。
