Module for liquid crystal display device having cushion members to prevent mechanical deformation and light leakage
View Patent ↗Disclosed is an LCD module that has a cushion member, or a plurality of buffer structures, which prevents mechanical deformation of the LCD panel, and the light leakage that results from the mechanical deformation. The plurality of cushion members are bonded to only a single inside edge of the panel guide and evenly distanced such that they provide a cushion to the LCD panel to reduce a concentrated weight generated by pressing due to the weight of the LCD panel. The cushion member, or the plurality of buffer structures, prevents mechanical deformation by distributing the weight of the LCD panel. The LCD module comprises an LCD panel, a backlight assembly, and a guide panel having the cushion member or buffer structures.
1. An LCD module comprising:
an LCD panel disposed on a front side of the module;
a backlight assembly disposed on a rear side of the LCD panel;
a panel guide seating the LCD panel; and
a plurality of cushion members bonded to only a single inside edge of the panel guide, the cushion members in contact with one outside edge of the LCD panel,
wherein the weight of the LCD panel is applied to the single inside edge of the panel guide when the LCD panel stands on the panel guide,
wherein each of the cushion members has a rectangular cube shape,
wherein the cushion members are substantially evenly distanced along the panel guide such that the entire rectangular surfaces of the cushion members that contact the LCD panel provide a cushion to reduce a concentrated weight generated by the pressure caused by the weight of the LCD panel,
wherein the inside edge of the panel guide includes a first surface and a second surface in a stepped shape,
wherein the cushion members are disposed on the first surface of the inside edge of the panel guide,
wherein the cushion members include poron.
2. The module according to claim 1 , wherein the cushion members is bonded to the inside edge of the panel guide.
3. The module according to claim 1 , wherein the backlight assembly comprises:
a plurality of lamps arranged in parallel to each other;
a reflector disposed at the rear of the plurality of lamps; and
a plurality of optical sheets disposed forward of the plurality of lamps.
4. The module according to claim 1 , wherein the panel guide comprises a resin material.
5. The module according to claim 1 , wherein the panel guide comprises polycarbonate.
