Abstract
Disclosed is an LCD cushion for a wireless mobile communication terminal, intervened between an LCD and an outer case to resiliently support the LCD against the outer case. The LCD cushion is manufactured by impregnating contractible fibers with a conductive material to prepare functional fabric pieces having shock absorbability and conductivity including a horizontal resistance of no greater than 1.0 Ω/mm2 and a vertical resistance of no greater than 1.0 Ω/mm2, integrally laminating selected functional fabric pieces into 1 to 4 layers having a total thickness of no greater than 1 mm using a conductive sticking agent, and then heat-fusion finishing an upper surface and outer and inner cut edges of the resultant laminated combination.

An LCD cushion for a wireless mobile communication terminal, intervened between an LCD and an outer case to resiliently support the LCD against the outer case, wherein the LCD cushion is manufactured by impregnating contractible fibers with a conductive material to prepare functional fabric pieces having shock absorbability and conductivity including a horizontal resistance of no greater than 1.0 Ω/mm2 and a vertical resistance of no greater than 1.0 Ω/mm2, integrally laminating selected functional fabric pieces into 1 to 4 layers having a total thickness of no greater than 1 mm using a conductive sticking agent, and then heat-fusion finishing an upper surface and outer and inner cut edges of the resultant laminated combination.
A method for manufacturing an LCD cushion for a wireless mobile communication terminal, comprising the steps of:
- impregnating contractible fibers with a paint containing a conductive material to prepare functional fabric pieces having shock absorbability and conductivity including a horizontal resistance of no greater than 1.0 Ω/mm2 and a vertical resistance of no greater than 1.0 Ω/mm2;
- selecting 1 to 3 functional fabric pieces and integrally laminating the selected functional fabric piece or pieces into 1 to 4 layers having a total thickness of no greater than 1 mm, using a conductive sticking agent;
- cutting the resultant laminated combination of the functional fabric pieces, employing an automatic die cutting machine, to define a shape which corresponds to that of an LCD of the wireless mobile communication terminal;
- primarily heat-fusion finishing an upper surface and outer cut edges of the resultant cut combination for 0.2˜0.5 seconds, while moving a small-sized flame projector;
- and
- secondarily heat-fusion finishing inner cut edges of the resultant combination which is primarily heat-fusion finished on its upper surface and outer cut edges, employing an electric soldering gun, so that an inner outline of the resultant combination is not changed and only a surface thereof is slightly fused.
