Infovision Optoelectronics Kunshan Co. | Date: 2015-03-16

The present invention provides a source driving circuit and an LCD device. The source driving circuit includes output channels, and each output channel includes a first switch element, a second switch element, a first output end, and a second output end. The first switch element and the second switch element are respectively connected to the first output end and the second output end. When the first switch element is turned on, the output channel outputs a display signal, and when the second switch element is turned on, the output channel provides recycled charges which are generated when the display signal is changed from a positive voltage to a negative voltage. The source driving circuit can recycle charges to make the most of charges generated when the display signals change from positive voltages to negative voltages and reduce power consumption of the LCD device.

A device and a method for image zooming are provided, in which two FIFO buffer units and a read/write control unit are added between a data storage unit and an image zooming unit. The read/write control unit respectively controls two FIFO buffer units to obtain and output the gray values of the pixels on the two adjacent channels to the image zooming unit in parallel. Then, the image zooming unit calculates gray values of pixels to be inserted between the two adjacent channels to finish interpolation. The image zooming unit need not read the gray values of the pixels on the two adjacent channels in the zooming direction from the data storage unit in series and in turn, but instead, may simultaneously read the gray values of the pixels on the two adjacent channels to pixels to be inserted from the two FIFO buffer units in parallel.

A blue phase liquid crystal material includes a liquid crystal host, a chiral reagent and a stable polymer. The chiral reagent is R811. The stable polymer is formed by photo-polymerizing a first monomer and a second monomer. The first monomer is 2-ethylhexyl acrylate (2-EHA), and the second monomer is 2-methyl-1,4-bis{4-[3(-acrylate)propoxyl]benzoicacid}phenylester (PTPTP). The blue phase liquid crystal material has a blue phase temperature range widened to an extremely low temperature. A blue phase liquid crystal composition and a method for manufacturing the blue phase liquid crystal material by using the blue phase liquid crystal composition are also provided.
