A method for forming a fused silica glass includes delivering a silica precursor to a burner and passing the silica precursor through the flame of the burner to form silica particles, depositing the silica particles on a planar surface to form a flat, porous preform, dehydrating the porous preform, and consolidating the porous preform into a flat, dense glass. The barrier includes four panels. The elongate member has an outer cross section. The first analyzer device is associated with a first coincidence function based on first measured electrical parameters of transmitted radio-frequency energy. By using this base architecture, to dissipate the heat generated in the backlight shield and accordingly heighten quality and prolong lifetime of a LCD component is expectable.
