[0097] 1. Overall structure

[0098] figure 1 It is an appearance plan view of the timepiece 1 as the electronic device of this embodiment.

[0099] The timepiece 1 is constituted as a digital display type electronic wristwatch and includes: an exterior case 10 having a rectangular opening 11 formed on the front; a wristband 12 ; and an electrophoretic display panel 30 visible through the opening 11 . In addition, a glass cover 11A is provided on the opening 11 , and operation buttons 131 to 134 are provided on the side surfaces of the exterior case 10 .

[0100] 2. The structure of the electrophoretic display module

[0101] figure 2 It is a plan view schematically showing the structure of the electrophoretic display module 3 . The electrophoretic display module 3 generally has an electrophoretic display panel 30 and a control circuit substrate 40 , which are connected to each other at a wiring part C by using an anisotropic conductive film (ACF; anisotropic conductive ...

no. 2 Embodiment approach

[0196] The display module 5 includes a display panel 50 as an electrophoretic display element and a driving device (not shown). The display panel 50 is configured such that microcapsules 330 ( Figure 4 ) of the electrophoretic layer, the detailed structural description is omitted. Pixel electrodes arranged in a matrix are arranged on the TFT substrate. Also, a voltage is applied between the pixel electrode and the common electrode by switching of the TFT corresponding to the image signal input.

[0197] The timepiece of this embodiment can display various times, and can Figure 20 The digital time display based on the numbers shown can also be Figure 21 The time display of hour hand 51 and minute hand 52 is shown as a digital display. When the hour hand 51 and the minute hand 52 are displayed, a marker 53 is displayed on the peripheral portion of the display panel 50 . Additionally, when switching Figure 20 display mode and Figure 21 In the display mode of the displ...

no. 3 Embodiment approach

[0206] Figure 26 A display module 7 is shown. The configurations of the display panel 70 and the driving device 80 are the same as those of the display panel 30 and the control circuit board 40 ( figure 2 ) have substantially the same structure, so descriptions are omitted. In addition, operation buttons 73, 74 ( Figure 30 ), the operations performed by the operation buttons 73 and 74 can be detected by the respective touch sensors 827 .

[0207] Figure 27 A state in which almost all of the segment electrodes 310 provided on the display panel 70 are displayed in black is shown. Along the circumferential direction of the display panel 70 ( Figure 27 In the middle length direction), numbers representing the hour, tenths and ones digits, characters representing time codes, etc. are scattered and arranged respectively.

[0208] In the normal mode for displaying the time, the hour, tens, and ones digits of the current time are displayed emphatically in black or white dep...

Abstract

The invention provides a drive method, drive device, display device, and electronic device for shortening display switch time dramatically in particle moving type display device. As a solving method, when the drive device drives a horologe display panel, the display panel processes display switch according with display color difference in unsaturated middle state by having middle color drive stepfor processing middle color drive. By processing middle color drive, especially in condition of processing repainting continuously, display switch time can be shortened dramatically in high repainting frequency, and power consumption is lower than condition of saturation driving.

Description

technical field [0001] The present invention relates to a particle-moving display device, a driving method thereof, a driving device, a display device, and electronic equipment. Background technique [0002] In recent years, various display devices of the particle transfer type represented by electrophoretic display elements (Patent Document 1) have been developed. Here, the electrophoretic display element causes charged particles (pigments, etc.) to migrate by applying an electric field, and the display color is determined by the color of the particles near the surface side in the viewing direction or the color of the solution in which the particles are distributed. In such a particle-moving display device, conventionally, the display is performed by moving the particles until the particles complete their migration and reach a saturated state. In the case of an electrophoretic display element, it takes about 2 seconds until a display redraw request is generated, rendering ...
