Electronic paper display device and method of manufacturing the same

The present invention provides an electronic paper display apparatus, which comprises: plural pairs of rotating balls each pair having a first rotating ball and a second rotating ball of a size smaller than that of the first rotating ball; a partition wall member having a plurality of cavities each in which a respective rotating ball is positioned and configured to transversely separate the plurality of rotating balls from each other; an electrode structure formed on the partition wall member and configured to provide a drive voltage to each of the plurality of rotating balls; and a plurality of distance adjusting members disposed inside the plurality of cavities, with being faced the plurality of rotating balls.

Electronic paper display apparatus and method thereof

A method of manufacturing a thin film device according to an aspect of the invention may include: preparing a substrate on which a sacrificial layer and a thin film to be transferred are sequentially formed; temporarily bonding the thin film to a circumferential surface of the transfer roll, and simultaneously removing the sacrificial layer to separate the thin film from the substrate at a first position of a transfer roll that is rolling; and transferring the thin film onto a sheet by running the sheet so that a surface of the sheet is bonded to the thin film temporarily bonded to the circumferential surface of the transfer roll. The substrate may be a transparent substrate.

Method of manufacturing thin film device

An electrophoretic display device includes: a transparent substrate positioned at a display side and having a transparent front electrode; a wiring substrate disposed to face the transparent substrate and having a field applying unit; a spacer disposed between the transparent substrate and the wiring substrate and having a plurality of accommodating holes with upper and lower portions open; and a plurality of microcapsules respectively positioned in the plurality of accommodating holes and including a dispersion solvent encapsulated with a plurality of charged particles contained therein, wherein the accommodating holes comprise upper holes with a width for receiving the microcapsules and lower holes allowing the microcapsules to be mounted thereon.

Electrophoretic display device and method for fabricating spacer for electrophoretic display device

An electronic paper display device and a method of manufacturing the electronic paper display device are disclosed. The method can include forming a plurality of relievo patterns on a lower board, in which the relievo patterns are formed to be independent and separated from one another, disposing a display unit in between the plurality of relievo patterns, and attaching an upper board on the plurality of relievo patterns such that the display unit is covered. In accordance with an embodiment of the present invention, the method can improve the freedom of disposing the display units by allowing partition walls to form only at areas to fix the display units.

Electronic paper display device and manufacturing method thereof

There are provided a display element and electronic paper. The display element includes a structure having a cylindrical shape and including a void inside, and at least two display regions formed on a side face of the structure and colored with different colors. The use of the display element for electronic paper can improve a response rate while lowering driving voltage, and can improve a contrast ratio by increasing a packing fraction.

Display element and electronic paper

A method for fabricating a thin film device includes the step of forming a sacrificial layer on a first substrate. A portion other than a region of the sacrificial layer is selectively removed. A material film is formed on the sacrificial layer to be connected to the first substrate via the selectively removed region. The material film portion filled in the selectively removed region is provided as an anchor. A thin film lamination is formed on the material film. The desired thin film device is formed by using a selective etching process. After removing the sacrificial layer, the thin film device floats over the first substrate with being supported by the anchor. A support body is temporarily attached on the thin film lamination. The thin film device is transferred to the support body onto a second substrate.

Fabrication method of thin film device

Provided is a sacrifice layer formed on a first substrate. A thin film laminated body is formed on the sacrifice layer. A separation groove exposing the sacrifice layer is formed to divide the thin film laminated body into at least one thin film device. The sacrifice layer is partially removed using a dry etching process. After the partial removal of the sacrifice layer, a remaining sacrifice layer region maintains the thin film device on the first substrate. A supporting structure is temporarily joined to the thin film device. The thin film device joined to the supporting structure is separated from the first substrate. Then, the remaining sacrifice layer is removed. The thin film device joined to the supporting structure is joined to a second substrate. Finally, the supporting structure is separated from the thin film device.
