Abstract
(EN)
The invention discloses a backlight module, a light guide plate and a preparation method of conductive hydrogel of the light guide plate. The light guide plate comprises a main body, wherein the mainbody of the light guide plate is made of an optical glass material, a cavity is formed in the light guide plate, the cavity is filled with the conductive hydrogel, and electrodes electrically connected with the conductive hydrogel in the cavity are arranged at two ends of the light guide plate, the conductive hydrogel is in a liquid state when not powered on, and the conductive hydrogel in the cavity is changed into a colloid state after being powered on. The light guide plate is advantaged in that tiny crystal particles are added into the conductive hydrogel, so light reflection and diffuse reflection functions of the light guide plate are enhanced, the light guide plate can enhance the light reflection and diffuse reflection functions of the backlight module, more light rays penetrate through the light guide plate to improve the lighting effect, quantum dots or the fluorescent powder is added into the conductive hydrogel, the color gamut of backlight can be further improved, and theeffect of the liquid crystal display device is better.
