Problems solved by technology

But if no voltage is applied at this time, the ink 18 will cover the surface of the hydrophobic layer 14 again, so that the light cannot be emitted.
In other words, this architecture must apply voltage to display, so it consumes a lot of power

Embodiment Construction

[0020] The first embodiment of the structure of the electrowetting display device proposed by the present invention is as follows figure 2 , image 3 As shown, the device includes a thin film transistor substrate 22 as a first substrate, a hydrophilic barrier structure 24 as a barrier structure, and a plurality of display units 25. The hydrophilic barrier structure 24 is located on the thin film transistor substrate 22, so as to The thin film transistor substrate 22 is divided into multiple areas, and each display unit 25 is respectively arranged on each area. Since the structures included in each display unit 25 are the same, therefore image 3 Only the structural cross-sectional view of the display unit 25 and the surrounding hydrophilic barrier structure 24 and the TFT substrate 22 is shown.

[0021] The display unit 25 includes at least one hydrophilic isolation structure 26, at least two electrode blocks 28, at least two hydrophobic insulating blocks 30, a colored liquid...

Abstract

The invention discloses an electrowetting-type display device, a drive method and a manufacturing method thereof. In the electrowetting-type display device, retaining wall structures are arranged on a substrate for dividing the substrate into a plurality of areas; at least two electrode blocks, at least two hydrophobic insulation blocks, at least one hydrophilic isolation structure, colored liquid and conducting liquid are arranged on each area; the electrode blocks and the insulation blocks are arranged on the substrate in turn; each isolation structure is positioned between adjacent two electrode blocks and adjacent two insulation blocks; the colored liquid is arranged on the insulation blocks; and the conducting liquid is filled in the space surrounded by the retaining wall structures for covering the insulation blocks and the isolation structure. In the electrowetting-type display device, the colored liquid is stabilized on the insulation blocks without the premise of applying a voltage, so that the display has a bistable display function and fulfils the aim of saving power.

Description

technical field [0001] The invention relates to an electrowetting display technology, in particular to an electrowetting display device, a driving method and a manufacturing method thereof. Background technique [0002] In the content of information, in addition to text and voice, video is also an important way, which can make the content of information more vivid. With the advancement of technology, images containing text can now be displayed on a display, especially a digital display composed of multiple pixel units. [0003] Please refer to Fig. 1(a), which shows the basic structure of an electrowetting display of general conventional technology, which is provided with a transparent electrode layer 12 and a hydrophobic layer 14 on a white substrate 10, and on the hydrophobic layer 14 is also provided with The retaining wall structure 16, in addition, ink 18 is dripped on the hydrophobic layer 14, and the ink 18 is located in the retaining wall structure 16, and finally t...
