Abstract:
1. A backplane for an liquid crystal displays (LCD) device, comprising: a first backplane units and a second backplane units each comprising a side wall close to lateral edges of a light guide panel (LGP) of the LCD device and a bottom portion below a bottom edge of the LGP; and an elastic device below the bottom edge of the LGP of the LCD device, the elastic device being arranged between the first and second backplane units; wherein the elastic device enables the first and second backplane units to relatively and elastically expand and contract horizontally, and the elastic device enables side walls of the first and second backplane units to relatively expand and contract horizontally; further comprising a third backplane unit arranged below the bottom edge of the LGP of the LCD device, the third backplane unit is arranged between the first and second backplane units, the elastic device are designated as a first elastic device and a second elastic device, two opposite ends of the third backplane unit are respectively connected to bottom portions of the first and second backplane units via the first and second elastic devices, the first elastic device enables the side wall of the first backplane unit to horizontally expand and contract relative to the third backplane unit, and the second elastic device enables the side wall of the second backplane unit to horizontally expand and contract relative to the third backplane unit; wherein the elastic device comprises springs; two ends of the springs are respectively arranged on the two adjacent backplane units, wherein the adjacent backplane units are configured with rivet bolts, the springs are configured with pulling hooks, and the pulling hooks are hung on the rivet bolts; or the adjacent backplane units are configured with integratedly punch-formed fixed blocks, and the pulling hooks of the springs are hung on the fixed blocks.
