Further, the included angle between the axis of the air blowing opening 10 on the first tube 11 and the horizontal plane is α, α=90°, so that the display panel 100 can be blown to the gas containing ions completely during the process of carrying the display panel 100 by the support platform 200 into the static electricity eliminating area. The included angle between the axis of the air blowing opening 10 on the second pipe 12 and the horizontal plane is beta, beta is more than or equal to 30 degrees and less than or equal to 60 degrees, and the arrangement of the second pipe 12 can enable the position with larger static electricity accumulation on the display panel 100 to blow the gas containing ions to the maximum extent so as to strengthen the static electricity neutralization effect on the bad high-emission area.
