Abstract: A wavelength conversion element including a substrate, a blocking wall structure layer, and a wavelength conversion layer is provided. The blocking wall structure layer is disposed on a surface of the substrate and defines multiple microgrooves. Reflectivity of the blocking wall structure layer is in a range of 1% to 99%. The wavelength conversion layer is disposed in the microgrooves and includes multiple wavelength conversion particles. A height of the blocking wall structure layer along a normal direction of the surface of the substrate is greater than a height of the wavelength conversion layer along the normal direction of the surface of the substrate. A backlight module adopting the wavelength conversion element is also provided.

Abstract: A quantum dot composition includes a matrix resin, a quantum dot phosphor, and a polysilane polymer. The matrix resin includes epoxy-fluorene copolymer acrylic resin represented by Formula 1: Formula 1. In Formula 1, R1 and R4 each is independently hydrogen or a C1-C12 long alkyl carbon chain. R2 and R3 each is independently a is an integer from 1 to 10, and b and c each is independently an integer from 0 to 10. X is 0.1 to 0.9. A color conversion film including the quantum dot composition and a backlight module using the color conversion film are also provided.
