Backlight module, light guide plate, and preparation method for conductive hydrogel thereof. 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.

A backlight module. The backlight module comprises: an LED chip (), a transparent support (), and a packaging adhesive (); an accommodating groove () is provided on the transparent support (), and the LED chip () is provided at the bottom of the accommodating groove (); the packaging adhesive () is located in the accommodating groove () and covers a light-exiting surface of the LED chip (). The LED chip () and the packaging adhesive () are provided in the accommodating groove (), so that the transparent support () and the packaging adhesive () enlarge a light-exiting angle of the LED chip (), thereby reducing the number of the LED chips () in the backlight module and reducing the production costs.

Backlight module

Disclosed is a television color cast adjustment method, including: dividing a television display screen into a plurality of areas according to a predetermined manner; determining an adjustment coefficient of red light and an adjustment coefficient of blue light in each area according to a position of each area relative to a light bar for the television display screen; adjusting initial image in each area according to the adjustment coefficients of red light and blue light thereof, and displaying the adjusted image in each area on the television display screen. Disclosed is also a television color cast adjustment apparatus. The present disclosure may solve the problem that the color cast appears on television display screens which is caused by the glass light guide plate, thus the viewing effect of TVs is improved.
