[0049] Overview of Electrophoretic Display Devices

[0050] figure 1 It is a diagram showing a schematic configuration example of an electrophoretic display device 1 according to one embodiment (first embodiment) of the present invention. figure 1 It is a plan view of the electrophoretic display device 1 .

[0051] The electrophoretic display device 1 includes a display unit 11 and a control unit 12 .

[0052] The display unit 11 is composed of a pixel group including pixels arranged vertically and horizontally (matrix). In the present embodiment, each pixel is divided by a partition wall, and each pixel has a pixel region 21 . Each pixel region 21 is filled with a dispersion liquid containing a dispersion medium and white particles and black particles. The control unit 12 performs white display using white particles or black display using black particles by individually controlling the voltage applied to the dispersion liquid for each pixel.

[0053] Here, the arrangement...

Abstract

The invention provides an electrophoretic display device, electronic apparatus, control device, and driving method capable of smooth display of color change. An electrophoretic display device including a first substrate and a second substrate which oppose each other, a first electrode provided on the first substrate, a second electrode provided on the second substrate, a region forming portion for forming a plurality of regions between the first substrate and the second substrate, a dispersion liquid which includes particles and a dispersion medium provided between the first electrode and the second electrode, and a control portion which applies a voltage to the first electrode, in which the first electrode is provided for a pixel, and when the control portion makes an adjacent first pixel and second pixel display the same color, the control portion applies voltages having different waveforms to the first electrode of the first pixel and the first electrode of the second pixel.

Description

technical field [0001] The present invention relates to an electrophoretic display device, an electronic device, a control device and a driving method. Background technique [0002] The electrophoretic display device (EPD: Electrophoretic Display) is used for electronic paper etc., for example. [0003] The electrophoretic display device applies a voltage to a solvent (dispersion medium) in which charged and dispersible particles are injected, and by moving the particles to a predetermined electrode side, the particles with different colors and reflectances can be separated to change the content of the display. . As an example, in a black-and-white display using particles corresponding to white (white particles) and particles corresponding to black (black particles), white is usually displayed by light scattering of white particles, and light absorption of black particles is used to display white. Sex to show black. [0004] Here, the electrophoretic display device has a ...
