    摘要: A method of recycling a cholesteric liquid crystal is provided. The method includes providing a display medium material containing a micro-encapsulated cholesteric liquid crystal. The display medium material is mixed with a hydrophilic solvent to form a mixture having a temperature of between 70° C. and 100° C. Then, a hydrophobic solvent is added to mix with the hydrophilic solvent. The display medium material, the hydrophobic solvent and the hydrophilic solvent are mixed to form a mixture having a hydrophobic layer and a hydrophilic layer. The hydrophobic layer and the hydrophilic layer of the mixture are separated, wherein the hydrophobic layer contains a cholesteric liquid crystal and the hydrophobic solvent. Then, the hydrophobic solvent is removed from the hydrophobic layer to obtain the cholesteric liquid crystal.

    摘要: A contrast control device is provided. The device of the invention includes a detecting unit, a judging unit, a backlight control unit, a gain generating unit and a contrast gain processing unit. The detecting unit calculates an average value and detects a maximum value of a current image. The judging unit generates a gain index and a brightness index according to the average value. The backlight control unit generates a backlight control signal according to the brightness index. The gain generating unit generates a first contrast gain value and a soft-clamping gain value according to the gain index, the average value and the maximum value and then selects one from the first contrast gain value and the soft-clamping gain value for output as a second contrast gain value according to an input pixel value of the current image. The contrast gain processing unit generates an output pixel value according to the second contrast gain value and the input pixel value.

    摘要: A method of reusing micro-encapsulated cholesteric liquid crystals is provided. The method includes providing a display medium material containing a micro-encapsulated cholesteric liquid crystal and a dispersant. The display medium material is mixed with a solvent to form a mixture having a temperature of between 40° C. and 60° C. A centrifugal process is performed to the mixture for separating the micro-encapsulated cholesteric liquid crystal and the dispersant. Then, the dispersant and the solvent are removed to obtain the micro-encapsulated cholesteric liquid crystal.
