The bidirectional shift register device of the invention is disposed on the substrate of the panel and includes multi-stages shift registers in series connection. Each stage shift register includes a pre-charging unit, a pull-up unit and a pull-down unit, in which the pre-charging unit receives a first preset clock signal and the output from a (i?1)th stage shift register or a (i+1)th stage shift register so as to thereby output a charging signal. The pull-up unit receives the charging signal and a second preset clock signal so as to thereby output a scan signal. The pull-down unit receives the second preset clock signal, a third preset clock signal and the output from the (i+2)th stage shift register or the (i?2)th stage shift register so as to decide whether or not pulling down the scan signal to a reference level.

Abstract: The gate of the first TFT in the present invention is discharged through the first TFT and the OLED in the compensation and data writing stage operation. As in cases that the usage time of the display pixel extends and the threshold voltage of the first TFT increases and the mobility thereof decreases, the voltage of the OLED increases, or the size of the display becomes larger to induce IR drop, the present invention enables to reduce the discharge voltage (charge current) to raise the gate voltage of the first TFT for compensating the OLED current drop. Meanwhile, the fifth TFT has characteristic of the threshold voltage increase. As the threshold voltage of the fifth TFT increases with usage time, the compensation of the OLED luminous efficiency drop can be realized.

Abstract: A refrigerating apparatus includes: a storage compartment, an air-circulating member, a refrigerating unit, and an electric field-generating unit. The storage compartment has an evaporator-side region and a cooling-side region. The air-circulating member is disposed to establish an air circulation path in which a to-be-cooled air flows from the cooling-side region to the evaporator-side region along an onward flow route, and in which a cooled air flows from the evaporator-side region back to the cooling-side region along a backward flow route. The refrigerating unit includes an evaporator disposed in the evaporator-side region, a compressor, and an expansion valve. The electric field-generating unit is disposed to impose a DC voltage over the onward flow route so as to minimize cohesion of water droplets in the evaporator-side region, thereby reducing phenomenon of frosting on the conduit body of the evaporator.

Abstract: A facial mask includes a permeable sheet and a nanometer metal layer coated on a side of the permeable sheet. The permeable sheet is made of adhesive-bonded fabric and is formed with a nose portion, three openings corresponding to eyes and mouth, and multiple split lines.
