Disclosed is a filler of a sealant a filler of a sealant and a method for manufacturing the same and a composite sealant. The filler of the sealant includes a filling material and a catalyst wrapped around the filling material. The catalyst includes a material provided to melt and generate a thermal reaction when a predetermined temperature threshold is exceeded. The predetermined temperature threshold is a minimum temperature at which the sealant is subject to thermocuring. A melting point of the filling material is higher than a maximal temperature during the thermocuring of the sealant. In the filler of the sealant, it is not necessary to change an initial composition and content of the sealant, the catalyst wrapped around the filling material is heated, and then melts and generates a thermal reaction to accelerate curing efficiency of the sealant during a thermocuring of the composite sealant. Therefore, a curing time of the composite sealant is shortened and a risk of liquid crystals to be contaminated is decreased.

The present disclosure provides a device for detecting a rotation angle of a prism and a method for using the same. The device for detecting a rotation angle of a prism is configured to detect, in the case that a prism film plate of a backlight module rotates relative to a display panel until the display panel displays a predetermined image, a rotation angle of the prism film plate relative to the display panel. The device for detecting a rotation angle of a prism includes: a stationary protractor; a film plate clamping mechanism configured to clamp the prism film plate; and a rotation mechanism which rotates the film plate clamping mechanism around an axis of the protractor. When the rotation mechanism drives the film plate clamping mechanism to rotate and the film plate clamping mechanism drives the prism film plate to rotate until the display panel displays the predetermined image, the rotation angle is detected based on an angle by which the film plate clamping mechanism rotates relative to the protractor.
