Title
(EN) QUANTUM DOT COLOR FILTER SUBSTRATE, MANUFACTURING METHOD THEREOF, AND DISPLAY PANEL
Abstract
(EN)

A quantum dot color filter substrate includes a substrate, a color filter layer, a quantum dot film layer, and a transparent conductive layer disposed between the color filter layer and the quantum dot film layer. The transparent conductive layer is externally connected to a power module to form a closed circuit. When a voltage is applied to the transparent conductive layer, the transparent conductive layer may generate heat, which can quickly remove solvents in a quantum dot film layer.
