Abstract: The present disclosure provides a method for manufacturing quantum dot color film substrate and quantum dot color film substrate. The method is to form a quantum dot adhesive by mixing a red quantum dot material, a green quantum dot material and a photoinitiator in a thermosetting adhesive. The photoinitiator itself does not destroy fluorescence properties of quantum dot, but the photoinitiator is cleaved and can quenching the fluorescence of quantum dot after UV irradiation. A selective quenching quantum dot layer is obtained after coating a quantum dot adhesive uniformly on a color filter layer, and the light mask is used to irradiate the quantum dot adhesive on the blue sub-pixel region. Free radicals are generated by cleaving photoinitiator and are quenching the quantum dot material directly; the method is capable of meeting requirement of high gamut, simple preparation process and low cost.

Abstract: A blue light absorption cut-off film and a blue light display device are provided. The blue light absorption cut-off film of the present disclosure is formed by a photoresist material including a resin, a yellow pigment, a dispersing agent, and a photoinitiator, and thus redundant blue lights in the blue light display device can be effectively absorbed to avoid the overall display effect thereof of tending to be blue. Also, the present disclosure provides a simple manufacturing method. The blue light display device of the present disclosure includes the above blue light absorption cut-off film, thus the redundant blue lights in the blue light display device can be effectively absorbed to avoid the overall display effect thereof of tending to be blue.

Abstract: The invention provides a liquid crystal display device, a liquid crystal display module and a liquid crystal cell thereof. The liquid crystal cell includes an upper substrate, a lower substrate, and a mixture of a quantum dot material and a liquid crystal material disposed between the upper substrate and the lower substrate. The quantum dot material includes a red quantum dot material and a green quantum dot material. A mass ratio of a total mixing amount of the two quantum dot materials occupied in a total mass of the mixture is 0.05˜5 wt %. As to the liquid crystal cell, the introduction of the QD material promotes the directional arrangement of liquid crystal molecules and thus plays a role of alignment; in another aspect, the liquid crystal cell being used in conjunction with a backlight source of blue or white LED can enhance the color gamut.
