Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electronic paper display panel having a vertical electrode structure,

The present invention relates to an electronic paper display panel having a vertical electrode structure and a manufacturing method thereof.

Some methods of constructing electronic paper include electrowetting, electrophoresis, rotating balls, and fine charge transfer.

Among these methods, there are a microcapsule method of E-ink and a microcup method of Saifics Inc. as a method of handling an electrophoretic fluid for electrophoresis. E-ink's microcapsule method combines a TFT (Thin Film Transistor) backplane with a microcapsulated sheet. This method poses a problem in the production of microcapsules, so that electrophoretic fluid is conveniently handled using a microembossing method in which the microcups are arranged in Cypiz's yarn.

Such a method requires a large-sized TFT backplane corresponding to the size of a large electronic paper. This increases the price of large displays and requires the introduction of large TFT backplane production equipment.

Especially, these methods have difficulties to implement the see-through function. Philips and others are attempting to implement a see-through function using in-plane switching. In the case of such a planar electrode, a plurality of electrodes are mixed on the same plane, causing problems in control, complicating the manufacturing process, and reducing the area of the electrodes used, resulting in a problem of inefficiency.

1 is a view showing the concept of an electronic paper for implementing the conventional see-through function of FIG. 1; FIG.

Referring to FIG. 1, the electrophoretic particles 50 are moved in the medium 60 by the electric potentials applied to the bottom electrode 40 and the vertical electrode 20 in (a) and (b). Each of the electrodes 40 and 20 is insulated from the electrophoretic particles 50 by the insulating layers 41 and 10. In order to utilize the electric field efficiently, the thickness of the insulating layers 41 and 10 must be extremely thin. The frame 70 maintains its shape and the electrophoretic fluid is sealed by the sealing films 30, 40. When the electrophoretic particles 50 are gathered on the bottom electrode 40 due to the potential applied to the bottom electrode 40 and the vertical electrode 20 and the potential of the bottom electrode 40 and the vertical electrode 20 is reversed The electrophoretic particles 50 are pushed to the area of the vertical electrode 20. That is, the electrophoretic particles 50 displaying the color disappear and become transparent, so that the background of the back surface is seen as it is.

1 (c) is a principle of an electronic paper using a rotating ball. In the conventional method, the rotating ball 51 is rotated by the potential applied to the upper electrode 30 and the lower electrode 40. It is necessary to introduce a method for increasing the rotational speed of the rotating ball 51. [

FIG. 2 is a conceptual view of the configuration of an electronic paper display panel according to a first embodiment of the present invention.

Referring to FIG. 2, pixels 430, which are capable of changing the focus to an electrical signal, are regularly distributed vertically and horizontally, and the intervals are very close to each other.

The pixel 430 is a pixel using the electrophoresis principle. A TFT (Thin Film Transistor), which is a driving element connected to each vertical electrode 120 for active driving (AM driving) of each pixel, has a vertical electrode for supplying an electrophoretic potential to the pixels 430, And a capacitor 440 is connected to each vertical electrode 120 in order to maintain a driving potential.

One electrode of the capacitor 430 is connected to the power source 400 through a common contact. The gates of the TFTs 450 connected to the vertical electrodes 120 of the horizontal row are commonly connected to constitute select lines 410 and select lines 420, One select line is turned on and the gate of the TFT connected to the select line is turned on at the same time and a source signal (pixel drive data) is supplied to the vertical electrode 120 connected to the TFT 450 do.

The source signal is connected in common with one electrode of the TFT of the column in order to give the driving potential to the vertical electrodes 120 of the column. In summary, if the TFT-ON signal is given to the selector 1 410, all the TFTs connected to the selector 1 410 are turned on and the vertical electrodes 120 connected to the source 1 211, the source 2 212, The electrophoresis driving potential is set. This potential is stored in the capacitors 440 connected to the vertical electrode 120.

When the selector 1 410 is turned off, all the TFTs connected to the selector 1 410 are turned off and the potentials of the capacitors 440 connected to the vertical electrode 120 are maintained to maintain the electrophoresis of the pixels.

When an electric signal is sequentially applied to the next select 2 420, all the connected TFTs are activated, and the potentials of the source lines are supplied to the pixels of the select 2 420.

In the latter part of the process, the components for the manufacturing process of the electronic paper display panel and the processing method by the combined structure of the components are described.

FIG. 3 is a perspective view showing an electronic paper raw fiber as a basic element for constituting a variable focus pixel in an electronic paper display panel according to a first embodiment of the present invention.

Referring to FIG. 3, it is preferable that the forming fibers 130 are fibers having uniform thickness and high surface precision, which are used for the convenience of the manufacturing process. In Fig. 3, although the cross section is circular, irrespective of the shape, the shape of the cross section is not particularly limited as long as it is convenient to use. Whether it is a circle or a rectangle, it can be convenient for constitution of a display panel.

Since the thickness of the insulating layer 110 and the vertical electrode 120 is about submicron and the TFT for the pixel driving is connected and the distance between the pixels is minimized, A forming fiber 130 is used.

The fabrication process uniformly covers the foaming fibers 130 with the insulating layer 110. The material of the insulating layer 110 is preferably a fluid capable of storing electric potential without electricity, but it is not limited thereto and various insulators can be applied.

The vertical electrode 120 is formed on the insulating layer 110 to make the electronic paper raw fiber 150.

Since the vertical electrode 120 is a vertically-shaped electrode, the vertical electrode 120 may not be a transparent electrode. The metal can be deposited by vapor deposition or sputtering. It is possible to coat uniformly with a submicron thickness. As an inexpensive manufacturing process, it is possible to produce a stabilized electrode by a light heat treatment process after coating using a wet coating method using a silver solution.

The foaming fibers 130 should be removed at the stage when the manufacturing process is completed.

If the foaming fiber 130 is plastic, the foaming fibers 130 must be readily soluble in the solvent to facilitate removal of the foaming fibers 130. The insulating layer 110 should not dissolve in the solvent.

If the foaming fiber 130 is a metal, the foaming fibers 130 should be readily soluble in acid or alkali to facilitate removal of the foaming fibers 130. The foaming fibers 130 in the cut state are easily removed because they are several hundreds micro-inches. There is a need for a process technique for preventing the vertical electrode 120 from dissolving.

As a method for eco-friendliness, a means for extracting the foaming fibers 130 with a physical force without melting them can be used. The insulating layer 110 is coated on the forming fibers 130 (not shown), and the vertical electrodes 120 are coated to form the raw paper 150 of the electronic paper. Here, the release material plays a role of separating the foaming fibers 130 from the insulating layer 110 easily. It is preferable to use the mold releasing material which has been studied and known, and it is not a key component in the practice of the present invention, and thus a detailed description thereof will be omitted.

4 is a perspective view of the driver sheet for constructing the electronic paper display panel according to the first embodiment of the present invention.

4, in order to drive the electronic paper display panel according to the embodiment of the present invention, the gate common TFTs 450 should be connected to the vertical electrodes 120 of the pixels 430 one by one.

Although the driver ribbon of the prior art in which the TFTs are arranged one-dimensionally on the ribbon can be used, a problem of alignment in the ribbon state is newly emerged.

In the embodiment of the present invention, a manufacturing process is performed in a sheet state, and a TFT is connected to each pixel by a cutting process. The final structure is in the form of a driver ribbon, but a sheet-state TFT is used until the completion of the process.

The driver sheet 200 has a gate electrode layer 205 formed on a flat and uniform base sheet 206 and a gate insulating layer 201 formed thereon. As shown in Fig.

The semiconductor line 202 is formed by depositing a semiconductor layer on the gate insulating layer 201 and scribing in a direction as shown in Fig. And later cut in a direction orthogonal to the semiconductor line 202 to form a ribbon.

The base sheet 206 is preferably made of an electrically insulating material and is formed of a material that is extremely thin in thickness and can function as a base sheet in order to increase the degree of freedom and resolution of the pixel 430.

5 is a perspective view of a condenser sheet for constituting an electronic paper display panel according to a first embodiment of the present invention.

Referring to FIG. 5, capacitors 440 for maintaining a driving potential should be connected to the respective pixels 430 one by one.

In the case of the condenser ribbon of the prior art, a precise alignment problem similar to that of the driver ribbon occurs.

The condenser sheet 230 is used in a manner similar to the use of the driver sheet 200 to facilitate the process. The common electrode 231 is formed on the base sheet 236 having a flat and uniform thickness and the dielectric sheet 232 is formed thereon and the independent electrode line 233 is formed thereon Respectively.

The dielectric 232 and the independent electrode line 233 can be formed by scribing the dielectric and the electrode over the entire surface of the common electrode 231. Another method is to transfer the dielectric made of another film and the independent electrode on the common electrode 231, thereby reducing the loss of the material.

6 is a perspective view illustrating a transparent sealing sheet 210 including a lower source electrode for constituting an electronic paper display panel according to a first embodiment of the present invention.

Referring to Fig. 6, a sheet used for bottom sealing of the electronic paper display panel is required. A transparent base sheet 212 of a super-high-grade optical material which is transparent and has no distortion is required for the construction of a see-through display panel. Here, for transparency of the transparent base sheet 212, all elements that may affect the transmission of light should be minimized. On the transparent base sheet 212, a source electrode line 211 capable of supplying a driving potential to the vertical electrode 120 is formed. The width and the thickness of the source electrode line 211 are almost negligible in the configuration of the pixel 430.

7 is a view schematically showing a first process of a method of manufacturing an electronic paper display panel according to a first embodiment of the present invention.

Referring to FIG. 7, on a prepared driver sheet 200, an electronic paper raw fiber 150 is placed on a semiconductor line 202 in the form of placing one electronic paper raw fiber 150 in one semiconductor line 202 in the longitudinal direction. 150).

Next, one source line connecting member 220 is placed in one semiconductor line 202. The electronic paper raw fiber 150 and the source line connecting member 220 are not in contact with each other and have only a contact surface with the semiconductor line 202. [

The source line connecting member 220 is a line having conductivity and is inserted later for convenient electrical connection with the source electrode line 211. [ It is preferable to adhere to the semiconductor line 202 of the driver seat 200 in advance for convenience of handling.

The source line connecting member 220 is attached to the semiconductor line 202 to constitute an electrical contact and then an insulating groove (not shown) is formed for facilitating the arrangement of the electronic paper raw fibers 150, It is preferable to dispose the raw fibers 150.

It is a method of increasing the electrical contact area by coating the conductive adhesive on the vertical electrode 120 of the electronic paper raw fiber 150 and then attaching it to the semiconductor line 202 in order to strengthen the electrical contact.

Next, the electronic paper raw fiber 150 is covered with the condenser sheet 230. The individual electrode lines 233 of the condenser sheet 230 are overlapped so that the electronic paper is long in the longitudinal direction of the raw fiber 150. And one electronic paper raw fiber 150 is connected to one of the independent electrode lines 233.

8 is a view schematically showing a second process of a method of manufacturing the electronic paper display panel according to the first embodiment of the present invention.

8, after the condenser sheet 230 is covered, a void filler 245 is filled in the hollow space and the driver sheet 200, the electronic paper raw fiber 150, and the condenser sheet 230 are compressed Then, the hardening filler 245 is hardened to complete the raw paper panel 290 of the electronic paper.

As the curing filler 245, epoxy, resin, silicone and the like are suitable. The property of the curing filler 245 is preferably a material convenient for the cutting process. In addition, the curing filler 245 may be transparent so that the entire electronic paper raw panel 290 filled with the curing filler 245 may be made transparent.

In order to facilitate filling of the curing filler 245, it is possible to fill the curing filler 245 and cover the condenser sheet 230 before covering the condenser sheet 230.

A variable focus pixel array can be manufactured in various ways from the following process.

First, the first method will be described.

The electronic paper raw panel 290 is cut into orthogonal to the longitudinal direction of the electronic paper raw fiber 150 to produce a one-dimensional arrangement 294 as shown in FIG.

Next, the one-dimensional array body 294 is pasted one by one on the transparent sealing sheet 210 including the lower source electrode. At this time, the one-dimensional array body 294 should be orthogonal to the source electrode line 211, and the source line connecting member 220 should be attached orthogonally to the source electrode line 211. Until the number of necessary pixels is reached.

On the other hand, it is possible to use a method of removing the forming fibers 130 and injecting an electrophoretic fluid before performing the cutting process for forming the one-dimensional array 294 with the raw paper panel 290 of the electronic paper. In this case, the electrophoretic fluid is filled in the original panel 290 with the electrophoretic fluid removed therefrom, and in the cutting process, the electrophoretic fluid remains in the generated holes due to the capillary phenomenon. Therefore, It is preferable to use a process of injecting a liquid to harden and coat it.

Next, the second method will be described.

FIG. 9 is a view schematically showing a third process of manufacturing the electronic paper display panel according to the first embodiment of the present invention.

Referring to FIG. 9, the electronic paper is applied with adhesive 240 on one side of the raw panel 290, and then stacked by the required number of pixels. The e-paper made from this process is called primitive bulk (295). Precise alignment process is required, but it is more convenient than other methods presented so far and has high precision after production.

As another method of the process, there is a method in which the electronic paper raw panel 290 is not completed and the curing filler 245 is used at the end. That is, a required number of the electronic paper raw fibers 150 is placed on one of the semiconductor lines 202 in the longitudinal direction on the driver sheet 200. Then, one source line connecting member 220 is placed in one semiconductor line 202. Thereafter, the electronic paper is coated with the capacitor sheet 230 on the raw fiber 150. The above process is sequentially performed to repeat the number of necessary pixels. Thereafter, the hardening filler 245 may be filled and cured to make the electronic paper raw bulk 295.
