Abstract: A touch panel module includes a frame, a base plate, a touch material layer, a transmission cable and a first attaching layer. The frame with an opening and a breach connected to the opening formed therein is disposed on a casing. The base plate is disposed on the casing and located inside the opening. The touch material layer is disposed on the base plate, and a peripheral portion of the touch material layer is attached to the frame for sealing the base plate inside the opening. The transmission cable is connected to the touch material layer in a position near the peripheral portion and passes through the casing via the breach. The first attaching layer attaches the frame and the casing for sealing a gap between the frame and the casing, so as to prevent liquids from entering the opening and the breach from the gap.

Abstract: A time limiter protects a light emitting diode coupled to an output of a current driver by preventing the light emitting diode from working overtime under a high current and from being overheated and burnt down, no matter whether a pulse width of an input pulse is larger or shorter than a delay time of the time limiter. The input pulse may be a periodic continuous input pulse, or a continuously-enabled pulse generated from a run-time error of software or hardware. The time limiter should be coupled with a discharging circuit for discharging the capacitor in the RC circuit while a periodic continuous input pulse was inputted, to keep the precise original pulse period and pulse width of the enabling signal to be outputted, and to prevent the time limiter from malfunctioning.
