Abstract: The invention provides a pixel driving circuit and LCD device. The pixel driving circuit electrically connects the drain of the third TFT of each sub-pixel in the N-th sub-pixel row to the first end of the second LC capacitor of a corresponding sub-pixel of the (N+1)th row. When driving, when scanning the N-th sub-pixel row, the third TFT of the N-th sub-pixel row turns on to release the voltage at the first end of the second LC capacitor of the N-th sub-pixel row to the first end of the second LC capacitor of the (N+1)th sub-pixel row, and does not affect the voltage on the array substrate common voltage line, thereby effectively ensuring consistent voltage value for various areas on the array substrate common voltage line. When applied to LCD device, the invention can improve the display quality of the LCD device.

Abstract: A hydrodeoxygenation catalyst takes self-made porous large-specific surface nano-alumina as a carrier, takes NixMoW, NixCoW or NixCoMo as an active component, and takes Mn as an assistant. Hydrothermal stability of the catalyst and dispersion of active components may be increased by enlarging a pore channel and a specific surface area of the carrier, thereby prolonging the life of the hydrodeoxygenation catalyst. A hydroisomerization catalyst takes multi-walled carbon nanotube composite hierarchical-pore-channel NiAPO-11 or NiSAPO-11 as a carrier and takes NixMoLa, NixCoLa or NixWLa as an active component. Due to the adding of the carbon nanotubes, the pore channel of the carrier is enriched, and connection between the active components and the carrier is effectively enhanced, thereby prolonging the life of the catalyst on a basis of increasing selectivity of aviation kerosene component. Moreover, the biological aviation kerosene satisfying usage conditions is prepared by virtue of mild reaction conditions.

Abstract: A LCD includes the sub-pixels arranged at least in two adjacent rows. The sub-pixels of the same color are interleaved with each other along the column direction. When the LCD displays a pure color frame, within the even-number arranging periods of the sub-pixels arranged along the column direction, a number of the sub-pixels of the same color being applied with the data signals having positive polarity are the same with the sub-pixels of the same color being applied with the data signals having negative polarity. In this way, the common electrode coupling caused by the transition of the data signals may be avoided. This eliminates the flicker issues and enhances the display performance of the LCD.
