Abstract: A backlight module and a display device are provided in the present invention. The backlight module includes a bottom polyester layer, an adhesive layer, a top coat layer, a silver reflective layer, an anchor coat layer, a polyester layer, and a grounding wire which overlap each other in sequence. A through hole in contact with the silver reflective layer is formed through the polyester layer and the anchor coat layer. The grounding wire is electrically connected to the silver reflective layer via the through hole.

Abstract: A polarizer and a display panel are provided. The polarizer includes a polarizer body and a through hole, and an inner diameter of one end of the through hole is greater than another end of the inner diameter, such that an optical adhesive layer is filled along a sidewall of the through hole. The through hole can be completely filled to prevent air bubbles from being generated between the optical adhesive layer and an inner sidewall of the through hole, thereby improving a yield of the display panel and improving a light transmittance of the through hole.

Abstract: A present disclosure provides a driving method for a liquid crystal display panel having steps of: the control chip simultaneously outputs a first selecting signal on a first voltage level, a second selecting signal on the first voltage level and a third selecting signal on the first voltage level to control the first transistors, the second transistors and the third transistors connecting between the buffers and each pixel column to be turned on; the buffers output a pre-charge signal to charge the sub-pixel units in each pixel column to the pre-charge voltage. Further, the present disclosure also provides a liquid crystal display device. The driving method for a liquid crystal display panel is effectively reduces the power consumption of the liquid crystal display device.
