Disclosed are an alkoxysilyl-containing A-B block copolymer formed from (meth)acrylate monomers as constituent monomers, characterized in that a polymer block of A chain has a number average molecular weight (Mn) of from 1,000 to 50,000 and a molecular weight distribution (Mw/Mn) of not greater than 1.6, a polymer block of B chain comprises alkoxysilyl-containing (meth)acrylate units as constituent monomer units, and the A-B block copolymer as a whole has a molecular weight distribution of not greater than 1.6, a process for the production of the block copolymer, a resin-treated pigment, and a pigment dispersion.
摘要:
Disclosed is a pigment dispersion containing at least a pigment, a liquid medium and a high-molecular dispersant. The high-molecular dispersant is a block polymer represented by A-B or A-B-C, in which A, B and C each represent a polymer block and the A and C blocks may be the same or different. The block polymer and its production process are also disclosed. The high-molecular dispersant is free of problems of a smell, coloration, a heavy metal and cost, and its use can provide a pigment dispersion excellent in the dispersion stability of a pigment.

A stereoscopic display includes an image displayer. The image displayer includes a display that is configured to sequentially display a right-eye image and a left-eye image. The display includes a first region that includes first rows and a second region that includes second rows. A method of driving the stereoscopic display includes sequentially repeating: writing first image data to the second region when the first region is in an image displaying state; setting the second region to the image displaying state and the first region to an image not-displaying state after the image data is written to the second region; writing second image data to the first region when the second region is in the image displaying state; and setting the first region to the image displaying state and the second region to the image not-displaying state after the second image data is written to the first region.

Provided is a method of driving an information display panel in which at least two types of display media comprised of particle groups containing chargeable particles are sealed between two opposed substrates, at least one substrate being transparent, and a voltage is applied across a pair of opposed pixel electrodes formed by providing conductive films to the respective substrates to move the display media, thereby displaying an information image, wherein, in a series of alternating voltage pulses applied at the time of deleting the information image displayed on the information display panel, there is provided an OFF time, which is a period during which application voltage of 0 volt is maintained during change of polarity of each pulse voltage. With this configuration, it is possible to provide a method of driving an information display panel capable of achieving the longer lifetime of a battery at the time when the panel is driven by the battery and of preventing drop of the voltage from a power supply, by reducing a peak value of the electric current occurring at the time of deleting with the alternating voltage.
