#CMT# #/CMT# The plate has capacitive and resistive touch plates (1, 2) combined with each other and including X- and Y-traces (12, 13) with two axial leads that are provided with two contacts at ends, respectively. The touch plate (2) has an upper current conducting sheet (22) arranged on a lower surface of a roof tile (21) when a lower current conducting sheet (23) is arranged on a surface of a base plate (24). The touch plate (1) is mounted on the touch plate (2), where signals of both the plates are transmitted to a signal processing unit (3) via signal output lines (16) and silver lines, respectively. #CMT#USE : #/CMT# Compound touch plate for use in electrical products. Uses include but are not limited to personal digital assistant (PDA), mobile telephone, MPEG audio layer-3 (MP3), electrical dictionary and global positioning system, mouse and touch keys for notebook. #CMT#ADVANTAGE : #/CMT# The capacitive touch plate is mounted on the resistive touch plate, so that sensitivity of the touch plates can not be reduced, and an indium-tin-oxide (ITO) film on the upper current conducting sheet is not influenced by stress, thus avoiding development of deformation, and hence increasing lifespan of the compound touch plate while achieving precise input of information. The utilization of the upper and lower current conducting sheets avoids damages and disturbances by electromagnetic interference (EMI) or static electricity. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a side sectional view of a combined touch plate. 1 : Capacitive touch plate 2 : Resistive touch plate 3 : Signal processing unit 12 : X-trace 13 : Y-trace 16 : Signal output lines 21 : Roof tile 22 : Upper current conducting sheet 23 : Lower current conducting sheet 24 : Base plate. |
