A display device including a pair of substrates, a display medium formed between the pair of substrates and including charged particles encapsulated therebetween such that an image is displayed by moving the charged particles electrophoretically, a drive unit that applies a voltage to the display medium, and a display control unit that controls a display of the display medium. After data communication for rewriting a display of a display device commences and before the data communication ends, the display control unit commences rewriting using a first waveform, and after completion of the data communication and after the rewriting using the first waveform, the display control unit executes rewriting using a second waveform.

Display device that rewrites with a first and second waveform and method of driving the display device that rewrites with a first and second waveform

A display device including a pair of substrates having surfaces facing each other and electrodes formed on the surfaces, respectively, a display medium having a memory effect and formed between the pair of substrates, and a drive unit that applies a drive voltage to the display medium. The display medium includes charged particles encapsulated therein such that movement of the charged particles based on a voltage applied by the drive unit provides display, and the charged particles include first particles for displaying a first color with application of a first voltage, second particles for displaying a second color with application of a second voltage having a polarity different from a polarity of the first voltage, and third particles for displaying a third color with application of a third voltage which has the same polarity as the polarity of the first voltage and an absolute value smaller than an absolute value of the first voltage.

Display device and driving method

A secondary battery metal terminal coating resin film having improved overall performance and capable of securing filling ability, adhesive properties, insulating properties of a lead end portion and shape retention properties of a sealant, a manufacturing method for the same and a battery pack using the secondary battery metal terminal coating resin film in provided in the lead end portion of a tab used for a laminate-type packaging material for a secondary battery. The secondary battery metal terminal coating resin film () according to the present invention is laminated, coating metal terminal () connected to a positive electrode or a negative electrode of a secondary battery. The melt flow rate of at least one layer of a resin that constitutes the resin film () is within a range from about 0.1 g/10 minutes to about 2.5 g/10 minutes.

Secondary battery metal terminal coating resin film, method for manufacturing same and battery pack

An electrical storage device terminal film which is arranged covering part of an outer peripheral surface of a metal terminal that is electrically connected to an electrical storage device body forming an electrical storage device. The terminal film includes a first outermost layer including a first insulating layer, a second outermost layer including a second insulating layer, and an amorphous insulating filler which is added to at least one of the first and second insulating layers. The amorphous insulating filler is arranged with a part thereof being protruded from an outer surface of the insulating layer.
