Main body of light guide plate is optical-glass material. Cavity is provided in light guide plate, filled with conductive hydrogel. Either end of light guide plate is provided with electrode electrically connected to conductive hydrogel in cavity. When not electrified, conductive hydrogel is in liquid state, when electrified, conductive hydrogel in cavity changes to gel state. Microcrystal particles are added to conductive hydrogel to improve light refection function and light diffuse reflection function of light guide plate and backlight module, to allow more light rays to penetrate through light guide plate to improve luminous efficacy. Addition of quantum dots or fluorescent powder to conductive hydrogel can further increase color gamut of backlight, such that liquid crystal display device has better effect."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Backlight module, light guide plate, and preparation method for conductive hydrogel of light guide plate","description":"Backlight module, light guide plate, and preparation method for conductive hydrogel thereof.
