Problems solved by technology

Therefore, there is a problem that, when the pixel is repeatedly driven in a state where the DC balance is broken, even if the color of the pixel is to be displayed using the predetermined driving waveform data, color deviation or the like may be seen. Issues that negatively impact long-term reliability

Abstract

Provided are a plastic microfluid control device having a multi-step microchannel and a method of manufacturing the same. The device includes a lower substrate, and a fluid channel substrate contacting the lower substrate and having a multi-step microchannel having at least two depths in a side coupling to the lower substrate. Thus, the device can precisely control the fluid flow by controlling capillary force in a depth direction of the channel by controlling the fluid using the multi-step microchannel having various channel depths. A multi-step micropattern is formed by repeating photolithography and transferred, thereby easily forming the multi-step microchannel having an even surface and a precisely controlled height.

Description

technical field [0001] The invention relates to a driving method of an electro-optic device, a driving device of the electro-optic device, the electro-optic device, electronic equipment and the like. Background technique [0002] Conventionally, as an example of such an electro-optical device, an electrophoretic display device is known. The electrophoretic display device has a structure in which an electrophoretic element including colored electrophoretic particles is sandwiched between a pixel electrode and a counter electrode, and an image is displayed by electrophoresis by applying a voltage between the electrodes to cause the electrophoretic particles to migrate. In this case, in the electrophoretic display device, for example, when electrophoretic particles colored in different colors are independently controlled to migrate for each color, it becomes possible to change the color of the displayed image. The electrophoretic element is composed of, for example, a pluralit...
