A light strip 6 is fixedly connected to the side of the curved LCD panel 1 and the inner wall of the curved back cover 3.
[0034] The black border area includes a curved light guide strip bonding area 7 and a curved glass cover plate bonding area 8; the curved light guide strip bonding area 7 is bonded to the curved light guide strip 4 with double-sided adhesive, and the curved glass cover plate bonding area 8 is bonded to the curved glass cover plate 2.
[0035] The curved glass cover bonding area 8 includes an inner double-sided adhesive bonding area 10 and an outer liquid adhesive bonding area 11. The inner double-sided adhesive bonding area 10 is bonded to the curved glass cover 2 with double-sided adhesive, and the outer liquid adhesive bonding area 11 is bonded to the curved glass cover 2 with liquid adhesive.
[0036] The curved LCD panel 1 is bolted to the curved back cover 3 via a mounting bracket 9.
[0037] The curved back cover 3 is bonded to the curved light guide strip 4.
[0038] The light strip 6 is bonded to the mounting bracket 9 on the side of the curved LCD panel 1.
[0039] The light strip 6 is bonded to the inner wall of the curved back cover 3.
[0040] The curved light guide strips 4 are symmetrically arranged on both sides of the curved LCD panel 1.
[0041] The light strips 6 are symmetrically arranged on both sides of the curved LCD panel 1 and on the inner sidewalls of both sides of the curved back cover 3.
[0042] The curved light guide strip 4 is adjacent to both sides of the curved glass cover plate 2.
[0043] like Figs. 1-3As shown, the top surface of the curved LCD panel 1 has an inherent black border area. The black border area of the curved LCD panel 1 is further divided into two parts: the curved glass cover bonding area 8 and the curved light guide strip bonding area 7. The curved glass cover bonding area 8 is used to bond the curved glass cover 2, and the curved light guide strip bonding area 7 is used to bond the curved light guide strip 4.
