As described above, in the thickness direction of the filter strip, the isolation rib 13 completely overlaps the filter body 10, so that the pressure generated by the glass holder 25 on the third pressing surface does not cause the isolation rib 13 to apply an eccentric moment on the filter body 10, thereby avoiding the situation that the filter body 10 is turned outwards and loosened.
In the interactive flat plate assembly state, the glass bracket 25 and the glass panel 30 are bonded and matched through the adhesive 252, so that the glass panel 30 is stably mounted on the glass bracket 25, wherein the adhesive 252 may be glue or double-sided tape. A mounting groove 251 for mounting the glass panel 30 is defined between the glass support 25 and the second pressing portion 12 and the isolation rib 13, when the glass panel 30 is disposed in the mounting groove 251, the glass support 25 and the second pressing portion 12 are respectively abutted against and matched with two opposite sides of the glass panel 30, and the isolation rib 13 is abutted against the second fixing rib 22 by a side portion of the glass panel 30, because the length of the isolation rib 13 is greater than the thickness of the glass panel 30, when the glass panel 30 is abutted against the second pressing portion 12, the isolation rib 13 protrudes out of a rear side surface of the glass panel 30 and abuts against the glass support 25, in order to ensure that the glass support 25 and the glass panel 30 can be stably matched, a double-faced adhesive tape, specifically a foam double-faced adhesive tape, is disposed between the glass support 25 and the glass panel 30, thus, while the distance between the glass support 25 and the glass panel 30 can be compensated, the hard connection between the glass support 25 and the glass panel 30 can be avoided, the risk of the glass panel 30 being broken by impact is reduced.
The interactive flat panel in this embodiment is described in detail below, and includes the above-mentioned multi-segment face frame assembly, the multi-segment face frame assembly is sequentially connected and encloses to define an installation space, and the glass panel 30 is connected with the face frame assembly and covers the installation space to form the touch panel of the interactive flat panel.
Through implementing above-mentioned technical scheme, can improve mutual dull and stereotyped part assembly stability, improve equipment quality, simultaneously, because the filter strip has avoided turning up, also improved mutual dull and stereotyped touch-control precision, let user operation experience better.
