Abstract: The present invention discloses an LED driving device with pulse width modulation (PWM) capable of preventing the LED display from flickering. The LED driving device primarily comprises a PWM unit for modulating the ON/OFF signal with a PWM cycle from one signal of higher resolution to two or more signals of lower resolution. The modulation is executed with the proviso that the duty cycle of the PWM cycle is almost or completely preserved. Accordingly, the LED will be lit more frequently and perform preset brightness with a higher refresh rate.

Abstract: A combinative electronic circuit element composed of a cube-shaped block having an electronic component assembled therein. The block contains a pair of recesses formed in one pair of its outer opposite surfaces and a pair of projections on another pair of outer opposite surfaces, hence a total of four block-engaging surfaces or four joints. To the bottom surface of each recess and to the top surface of each projection is fixed a contact plate, which is then connected to said electronic component within said block so that upon engagement of a recess of one block with a projection of another block, the two electronic components housed in the two blocks are in communication with each other. A plurality of blocks each containing a different electronic component can be put together according to a given electronic circuit diagram by bringing said recess and projection into union so as to form a complete electronic circuit.
