Problems solved by technology

[0006] However, when a segmented electrophoretic panel is used as the display unit, the display device cannot realize high-definition display compared with the case of using an active matrix electrophoretic panel.
On the other hand, when an active matrix electrophoretic panel is used as the display unit, the display device cannot switch display images at a high speed compared with the case where a segmented electrophoretic panel is used.

Embodiment approach

[0037] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 It is a figure which shows an example of the external appearance of the electronic device 1 of this embodiment. Such as figure 1 As shown, in this example, the electronic device 1 is a timepiece having an electro-optical display device 10 . The electronic device 1 displays the minute hand M1 , the hour hand M2 , the second hand S, and the graph G on the display unit 11 of the electro-optical display device 10 . For example, graph G is a bar graph showing the number of steps per hour of users who carry electronic device 1 .

[0038] In addition, the electronic device 1 may be configured to display other information, or may be configured to display other information without displaying some or all of the information. In addition, graph G may also be other graphs. In addition, the electronic device 1 may be other electronic devices including the electro-optical d...

specific example 1

[0096] Below, refer to Figure 8 , a specific example 1 of the control method of the electro-optical display device 10 according to the present embodiment will be described.

[0097] Figure 8 It is a timing chart in Specific Example 1 of the control method of the electro-optical display device 10 . exist Figure 8 The figure shows a state in which the electro-optic display device 10 operates in order of an image signal input period T1, a matrix display mode period T2, a power-off period T3, a segment display mode period T4, and a repetition period T5 to display a display image. In addition, the segment display mode period T4 is divided into a first half period and a second half period. That is, in the segment display mode period T4, the electro-optical display device 10 operates in the order of the first segment display mode period T4-1 and the second segment display mode period T4-2.

[0098] Figure 8 Among the potential V1 of the first control line 36, the potential V...

specific example 2

[0143] Below, refer to Figure 9 , a specific example 2 of the control method of the electro-optical display device 10 according to this embodiment will be described.

[0144] Figure 9 It is a timing chart of a specific example 2 of the control method of the electro-optical display device 10 . exist Figure 9 The figure shows that the electro-optical display device 10 operates in the order of image signal input period T1, matrix display mode period T2, power off period T3, segment display mode period T4a, and repeat period T5a to display images. In addition, the control method of the electro-optical display device 10 during the image signal input period T1, the matrix display mode period T2, and the power-off period T3 is the same as Figure 8 The method described in is the same, so the description is omitted.

[0145]

[0146] Hereinafter, the segment display mode period T4a will be described.

[0147] During the segment display mode period T4a, the electro-optical di...

Abstract

An electro-optical display device includes a first substrate on which a plurality of pixel electrodes are provided; a second substrate on which an opposing electrode that faces the pixel electrodes and is divided into a plurality of segments is provided; an image forming unit that is provided between the first substrate and the second substrate and forms a display image according to an electric potential applied to the pixel electrodes and an electric potential applied to the opposing electrode; and a control unit that causes the image forming unit to form a display image based on a first display mode in which approximately the same electric potential is applied to a part or all of the segments in the opposing electrode and a second display mode in which approximately the same electric potential is applied to one or more of the pixel electrodes.

Description

technical field [0001] The present invention relates to an electro-optical display device, an electronic device and a driving method. Background technique [0002] Display devices that display images using electrophoretic particles and / or flying particulates, electrochromic changes, etc. are being researched and developed. [0003] In contrast, there is known a display device in which a display portion is configured using either a segment type electrophoretic panel or an active matrix type electrophoretic panel (see Patent Document 1). [0004] prior art literature [0005] Patent Document 1: Japanese Patent Laid-Open No. 2010-197563 [0006] However, when a segment-type electrophoretic panel is used as a display unit, the display device cannot realize high-definition display compared with a case where an active-matrix type electrophoretic panel is used. On the other hand, when an active matrix electrophoretic panel is used as a display unit, the display device cannot swi...
