Abstract: A current amplifying circuit includes a first FET transistor, a light receiving unit and a functional unit. The light receiving unit is connected with a first gate terminal of the first FET transistor through an enabling line. The functional unit is connected with a second conduction terminal of the first FET transistor. When the light receiving unit absorbs a light beam, a forward photoelectric current or a reverse photoelectric current is generated. The forward photoelectric current or the reverse photoelectric current flows to the first gate terminal through the enabling line. Consequently, an enabling voltage at the first gate terminal is increased and the first FET transistor is turned on. When the first FET transistor is turned on, an enabling current flows through the first FET transistor to enable the functional unit.

Abstract: An optical amplifying module and a manufacturing method are provided. The optical amplifying module includes a current amplifying element, a light emitting element and a light receiving element. A main substrate of the current amplifying element has a first surface and a second surface, which are opposed to each other. Moreover, plural first main electrodes are installed on the first surface, and plural second main electrodes are installed on the second surface. The light emitting element is installed beside the first surface of the current amplifying element. The light emitting units of the light emitting element are electrically coupled with the corresponding first main electrodes. The light receiving element is installed beside the second surface of the current amplifying element. The light receiving units of the light receiving element are electrically coupled with the corresponding second main electrodes.

Abstract: A transparent organic light emitting diode (OLED) includes a transparent substrate; transparent anodes on the transparent substrate and bridged by an insulating layer; at least an isolation pillar provided above the insulating layer; an organic light emitting layer coated on the surfaces of the transparent anodes and the isolation pillars; and a metal cathode coated on the surfaces of the organic light emitting layer on the transparent anodes. When light passes through the transparent OLED, only the areas where the metal cathode is coated will affect the light transmittance, and the rest of the areas not coated with the metal cathode may maintain a better transmittance. By reducing the coating area of the metal cathode, the transparent OLED is able to increase its transmittance accordingly.

Abstract: A hexacene derivative is described, being expressed by formula (1): wherein X1-X6 denote the presence or absence of a carbonyl bridge [—C(?O)—], with a proviso that at least one of X1-X6 is a carbonyl bridge while any six-member ring absent of a carbonyl bridge is aromatic. A method for forming hexacene is also described, including: thermally treating the hexacene derivative to expel volatile units of CO from the hexacene derivative.
