  • Patent number: 10528161
    Abstract: A manufacturing method of a touch panel includes following steps. The first sensing electrodes and the second sensing electrodes are formed on a substrate first. Connecting bridges are formed next, wherein adjacent two first sensing electrodes are connected by at least one connecting bridge, and a manufacturing method of the connecting bridges includes following steps. A metal layer is formed on the substrate first, wherein a material of the metal layer includes silver. A photoresist layer is formed on a surface of the metal layer next, wherein a material of the photoresist layer includes sulfur. A photolithography process and an etching process are respectively performed on the photoresist layer and the metal layer to form the connecting bridges, wherein silver in the metal layer and sulfur in the photoresist layer react with each other to form a silver sulfide layer after the photoresist layer is formed.

  • Patent number: 8143793
    Abstract: An energy efficient illumination device is provided in which energy consumption is reduced by using a pulse generating circuit which provides power to LEDs in short pulses, and in which the circuit has a lifespan which is comparable to that of an LED. The illumination device includes a pulse generator circuit employing only passive circuit components and which is used to generate a desired pulsed and positively DC biased output waveform. The pulse generator circuit receives alternating current power as an input, alters the power waveform, and supplies the power to LEDs for a very short time (0.2-15 ms) during each cycle of a 50-60 Hz input signal. This paradigm of pulsed light emission provides ambient lighting that is perceived by humans to be steady and continuous, and which also provides substantial energy savings since power is used in only a fraction of the power cycle.
