Publication number: 20180108296Abstract: A pixel compensation circuit is arranged for compensating the critical parameter associated with the electrical properties of the components in thin film transistors of an active matrix organic light emitting diode display or similar illumination systems to avoid uneven brightness resulted from the voltage drop effect. The pixel compensation circuit is defined in a sub-pixel area, wherein there are eight thin film transistors and one capacitor, and the circuit is operated by two control signals. In contrast, three control signals are required in the conventional technologies. The fewer control signals are required, which is benefit to the flexibility of the layout and design of specification.Type: ApplicationFiled: September 12, 2017Publication date: April 19, 2018Inventor: SHIH-SONG CHENG

Publication number: 20180096732Abstract: The present invention discloses a high stability shift register with adjustable pulse width to be achieved by a circuit structure through purely N-type transistors or purely P-type transistors. The structure comprises eight thin film transistors and a capacitor, and uses the 8T1C structure as a repeating unit. The invention can obtain an output signal from an input signal, two DC signals and two AC signals. The AC signal is a two line-time frequency pulse wherein the pulse width is smaller or equal to the line-time. The output signal will shift a line-time on the time axis with the input signal, and as an input signal to the next shift register in sequence. Compared with the conventional technique, the invention reduces the amount of the components to obtain a high stability and adjustable pulse width shift register.Type: ApplicationFiled: October 2, 2017Publication date: April 5, 2018Inventor: SHIH-SONG CHENG

Publication number: 20050147776Abstract: A bottle container provided with a protective layer is provided by coating a protective layer composed of a nanoscale titanium dioxide (TiO2) and copper particle on the surface of a bottle container, characterized in that, when sunlight irradiates over the bottle container, UV light or visible light of shorter wavelength (=about 600 nm and less), they will be absorbed therein and generates subsequently electrons and electric holes to react water and oxygen in air into active oxygen and hydroxyl free radical as strong oxidants. These oxidants can decompose surrounding organic matters and can kill bacteria as well as de-odor. In case of thus coated bottle container containing beer, UV light or strong light cannot enter substantially into the beer contained therein to oxidize hop components in the beer, and consequently, the intact taste of the beer can be retained.Type: ApplicationFiled: January 2, 2004Publication date: July 7, 2005Inventor: Meng-Song Cheng
