Embodiment 1

[0021] The dimming film cutting method of the present embodiment comprises the following steps:

[0022] Step 1: Take a roll of dimming film with the same batch number. like figure 1 As shown, the dimming film includes a first substrate layer 1 , a first conductive layer 2 , a PDLC layer 3 , a second conductive layer 4 and a second substrate layer 5 stacked in sequence. The dimming film is unfolded and squared on the cutting table 6 .

[0023] Step 2: Adjust the existing cutting hob 7 to be inclined at an angle of 45° to the vertical surface perpendicular to the cutting table 6, and then cut according to the required size and surface size to obtain the dimming film 1. Dimming film 2, Dimming film 3, Dimming film 4 and Dimming film 5.

[0024] Step 3: Wipe the cut edges with alcohol to ensure that no impurities remain.

[0025] Step 4: Make electrodes on the dimming film.

[0026] Test the dimming film: test with 48V electricity, dimming film 1, dimming film 2, dimming fil...

Embodiment 2

[0028] The dimming film cutting method of the present embodiment comprises the following steps:

[0029] Step 1: Take a roll of dimming film with the same batch number.

[0030] Step 2: Adjust the inclination angle of the cutting table so that the angle between the plane where the cutting hob is located and the normal line of the cutting table is 30°, and spread the dimming film squarely on the cutting table. Then cut according to the surface size below the required size to obtain the six dimming films, seven dimming films, eight dimming films, nine dimming films and ten dimming films.

[0031] Step 3: Wipe the cut edges with alcohol to ensure that no impurities remain.

[0032] Step 4: Make electrodes on the dimming film.

[0033] Test the dimming film: test with 48V electricity, dimming film 6, dimming film 7, dimming film 8, dimming film 9 and dimming film 10 can light up normally. Test with 60V electricity, dimming film 6, dimming film 7, dimming film 8, dimming film 9 ...

Abstract

The invention relates to a dimming film cutting method and a prepared dimming film thereof. The method comprises the following steps that: the angle between a cutting knife and the dimming film is adjusted, so that the plane where the cutting knife is located inclines at the inclination angle of 30-45 degrees relative to the normal of the dimming film; the dimming film comprises a first conductive layer, a polymer dispersed liquid crystal layer and a second conductive layer which are stacked in sequence; and the cutting knife cuts the dimming film at an inclined angle. According to the method, the problems of edge short circuit and incapability of normal bright spots caused by vertical cutting of the current dimming film can be solved, and the rate of finished products is improved.

Description

technical field [0001] The invention relates to the technical field of dimming films, in particular to a cutting method for dimming films and a dimming film prepared therefrom. Background technique [0002] The dimming film is a new type of electronic light control product. Through the control of an external electric field, the rapid transformation of the dimming film between the colorless transparent state and the frosted scattering opaque state can be realized. The double requirement to protect privacy. Specifically, when the power is turned off, the liquid crystal molecules are arranged in disorder, and the dimming film is in a scattering state; when the power is turned on, the liquid crystal molecules are oriented under the action of the electric field, and the dimming film allows light to pass through. After roll-to-roll production, the dimming film is cut according to different usage scenarios to meet the required size specifications. Most of the existing cutting meth...
