Embodiment Construction

[0037] An electrowetting display device according to an embodiment of the present invention will be described below. However, it can be easily understood that the embodiments provided in the present invention are only used to illustrate the making and use of the present invention in a specific way, and are not intended to limit the scope of the present invention.

[0038] Please refer to Figure 1A , which shows a schematic cross-sectional view of an electrowetting display device before a voltage is applied according to an embodiment of the present invention. The electrowetting display device includes a first substrate 100 and a second substrate 200 opposite to the first substrate 100 . In this embodiment, the first substrate 100 and / or the second substrate 200 includes glass, metal or plastic material.

[0039] In other embodiments, the first substrate 100 and / or the second substrate 200 may also include a flexible flexible substrate, such as polyethylene terephthalate (poly...

Abstract

An electro-wetting display device is provided. The device includes a first substrate and a second substrate disposed opposite thereto. A plurality of first electrodes and a plurality of corresponding second electrodes are disposed on the first substrate and face the second substrate. A barrier layer is between the plurality of first electrodes and the plurality of second electrodes, such that the plurality of first electrodes is electrically insulated from the plurality of second electrodes. A plurality of ribs is on the first substrate to form a plurality of pixel regions. A polar liquid and a non-polar liquid are between the first and second substrates. The barrier layer is between the polar liquid and at least one of the plurality of first electrodes and the plurality of second electrodes, and the non-polar liquid is in direct contact with the barrier layer in each pixel region.

Description

technical field [0001] The present invention relates to a display device, in particular to an electrowetting display device. Background technique [0002] With the rapid development of optoelectronic technology, various displays are also flourishing. Electro-wetting display (EWD) devices have attracted attention due to their advantages of high light utilization, high response time, low power consumption and high resolution. [0003] A general electrowetting display includes: non-polar oil droplets, polar liquid, hydrophobic surface (hydrophobic layer) and hydrophilic barrier structure (hydrophilic rib), wherein non-polar oil droplets are placed on the hydrophobic surface, and non-polar The polar oil droplets are separated by a hydrophilic barrier structure, and the polar liquid is above the non-polar oil droplets. The principle of operation is as follows: When no voltage is applied to the display, non-polar oil droplets spread out on the hydrophobic surface, thus taking on...
