  • Patent number: 7248305
    Abstract: An LCD module is associated with a pair of switches, one of which is depressed by pressing the LCD module to swivel in a seesaw operation. The LCD module has a front panel having a larger thickness than and thus capable of protecting the LC layer and the rear panel against a reasonable external load for pressing the front panel for switching. The LCD module is suited for use in a portable terminal having a smaller space for switches and LCD module.
