The first filter unit 600 includes at least a first filter 610 and a second filter 620, and the filter band of the first filter 610 is different from the filter band of the second filter 620.
In this embodiment, the frame glue curing apparatus 100 further includes a first driving unit. The first driving unit is connected with the computer and used for driving the light filtering unit to rotate.

In this embodiment, the first filter 610 is used to reject light with a wavelength less than 340nm, and the second filter 620 is used to reject light with a wavelength less than 380nm, refer to fig. 1. The frame glue coating and the liquid crystal dripping of the display panel are simultaneously carried out, and the liquid crystal contains a reactive monomer which is used for reacting under the irradiation of ultraviolet rays in the ultraviolet alignment process so as to form the pretilt angle of the liquid crystal. The reaction light wave band of the frame glue is smaller than 420nm, and the common reaction monomers in the liquid crystal mainly react in the light wave band smaller than 320 nm. The current ultraviolet light sources used for curing the frame glue are metal halogen lamps or fluorescent lamps, and the light emitted by the light sources is of full wavelength and has all wave bands. Therefore, under the light source, the frame glue and the reactive monomer in the liquid crystal can react. At present, due to the demand of electronic contest products, a new liquid crystal material is developed, and the liquid crystal reaction type monomer needs to react in a 365nm wave band and coincide with a frame glue reaction wave band. Therefore, the band of the cured frame glue needs to be moved further towards the long wave direction, and the light wavelength is required to be in the light band larger than 380 nm.
