Abstract: A nanoimprint template is provided, including a main template, a plurality of photoresist micro-structures arranged on the main template, and a fluororubber polymer layer coated on an outer layer of the photoresist micro-structures. The fluororubber polymer layer has a bonding function with the main template, so as to fixedly connect to the surface of the main template. The nanoimprint template can not only protect the photoresist microstructure therein, but also prevent the nanoimprint template from being deformed during operating, thereby improving the process quality. Moreover, the surface oil resistance and corrosion resistance of the nanoimprint template is improved, so that the surface has lower surface energy, which can effectively improve the degumming problem during operating. A manufacturing method of the nanoimprint template and the application thereof in manufacturing a microstructure substrate are also provided, the microstructure size and shape of the formed microstructure substrate can be ensured.

Abstract: The invention provides a luminance adjustment method and apparatus for RGBW LCD, which uses first and second EOTFs to generate a grayscale luminance lookup table for RGBW LCD, and makes the grayscale-luminance relation in lookup table corresponding to the first EOTF within the grayscale interval between 0 and grayscale threshold; the grayscale-luminance relation in lookup table corresponding to the second EOTF within the grayscale interval between grayscale threshold and 255; the curve slope of the second EOTF greater than the curve slope of the first EOTF within the interval between second luminance threshold and maximum luminance value. By adopting different EOTFs for low and high grayscale intervals, the method considers the poor dark state characteristics of LCD and characteristics of RGBW LCD having higher maximum luminance, and improves the display capability of RGBW LCD in details of high grayscale images.

Abstract: The present invention provides a reflective liquid crystal display device, which includes an upper substrate and a lower substrate that are opposite to each other, a liquid crystal layer arranged between the upper and lower substrates, a transparent plastic layer bonded to a surface of the lower substrate that is distant from the liquid crystal layer, and a mirror-reflection layer that is attached by the transparent plastic layer to the surface of the lower substrate. The transparent plastic material of the transparent plastic layer for attaching the mirror-reflection layer contains therein transparent particles and the transparent plastic material and the transparent particles have different reflectivity so as to provide an effect of diffuse reflection. Namely, the transparent plastic layer and the mirror-reflection layer are combined together to provide a diffuse-reflection layer, so that compared to the conventional reflective liquid crystal display devices, there is no need to conduct an additional process for forming a diffuse-reflection layer, thereby simplifying the manufacturing of the diffuse-reflection layer and reducing the difficulty and cost of the manufacturing.

Abstract: A fast response liquid crystal display panel includes a first comb electrode arranged on a surface of an upper substrate that is adjacent to a liquid crystal layer and a second comb electrode arranged on a surface of a lower substrate that is adjacent to the liquid crystal layer. The first comb electrode includes a plurality of first elongate electrodes that are parallel to and spaced from each other and the second comb electrode includes a plurality of second elongate electrodes that are parallel to and spaced from each other. The plurality of first elongate electrodes and the plurality of second elongate electrodes are parallel to each other in a lengthwise direction thereof and are shifted with respect to each other and alternate with each other in a widthwise direction thereof. Application of electric voltage to the first comb electrode and the second comb electrode causes the liquid crystal molecules of the liquid crystal layer to undergo both splay deformation and twist deformation, increasing the deformation elastic constant of the liquid crystal molecules and making liquid crystal display panel speeding up the response time to perform a fast response.
