Description

Technical Field [0001] The present invention relates to a power supply terminal for a polymer dispersed liquid crystal display device,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a power supply terminal of a polymer dispersed liquid crystal display device and a method of manufacturing the same, and more particularly to a polymer dispersed liquid crystal display To a power supply terminal of a display device and a method of manufacturing the same.

Due to the development of the information and communication industry, there is an increasing demand for the development of flat panel display technology due to the need for thin, lightweight and low power consumption which emphasizes the demand for high resolution and large screen and portability.

Accordingly, flat panel display devices such as EL (Electro-Luminescence), FED (Field Emission Display), PDP (Plasma Display Panel), and LCD (Liquid Crystal Display) have been developed. However, EL display devices, such as EL, FED and PDP, have a drawback that their luminous efficiency is low and high voltage is required. On the other hand, the LCD is a light-receiving type display device, and operates in a low voltage and a low power consumption. The LCD is different from other display devices. However, LCD has a low luminance and a viewing angle dependency. In case of making a large LCD, it is very difficult to form an alignment film on a wide substrate and to seal the liquid crystal uniformly. In addition, in the case of forming a large screen, since the number of electrodes is increased, the duty ratio of the voltage waveform applied to each electrode decreases, and an LCD with a slow response speed gives a rich yearbook in moving picture display.

In recent years, a polymer dispersed liquid crystal (PDLC) display device in which a porous film is impregnated with a low molecular weight liquid crystal has been developed as a solution to some of these problems. The PDLC has a thin film structure formed by impregnating a polymer matrix or a crosslinked polymer matrix with a nematic liquid crystal having a positive anisotropy of dielectric constant between indium tin oxide (ITO) substrates. In such a structure, since the low-molecular liquid crystal is randomly oriented to the outer wall of the polymer matrix, the light scattering occurs and becomes opaque. However, when a voltage is applied, liquid crystals are arranged along the longitudinal direction to transmit light, do.

Accordingly, there is an advantage that not only an alignment film and a polarizing plate used in a twisted nematic (TN) type LCD are required, but also a process is simplified and an intensity of transmitted light is increased, as well as a viewing angle is improved.

That is, the polymer dispersed liquid crystal display device is formed by coating a thin film of a plastic film with an ITO electrode to form a conductive film, and coating a polymer dispersed liquid crystal between the formed upper and lower conductive films, The glass substrate is bonded on the upper and lower sides and is used in various structures for various purposes.

In the polymer dispersed liquid crystal display device formed in this way, electricity necessary for driving is required for the characteristics of the product, and an electrode terminal (Electric Terminal) should be formed and connected to the outside.

Examples of such techniques are described in documents 1 and 2 below.

For example, as shown in Fig. 1, the following Patent Document 1 discloses a method in which ITO is coated on a thin film of a plastic film to form a conductive film, and a polymer dispersed liquid crystal is coated and injected between two conductive films thus formed Forming a PDLC panel (5), half-cutting and removing one piece of the two conductive films and a part of the polymer-dispersed liquid crystal, cutting out the remaining one piece of the conductive film, Forming a conductive material layer by coating a silver paste (17) on the ITO of the remaining one conductive film on which the cutting portion is formed, forming conductive conductive tape (19) on the conductive material layer And a step of connecting the external wire (7) to the middle of the copper tape (8) across the empty space of the cutting portion It discloses a method for manufacturing.

Patent Document 2 discloses a thin film transistor, a lower substrate on which first and second electrodes are formed, an upper substrate on which a black matrix is formed, first and second reflectors formed diagonally between the upper and lower substrates, A liquid crystal layer of polymer dispersed type formed between the upper and lower substrates so as to be disposed below the black matrix between the upper and lower substrates, a first resin layer supporting the first reflector between the upper substrate and the lower substrate, And a second resin layer supporting the second reflector between the lower substrate and the lower substrate, wherein the polymer dispersed liquid crystal layer comprises a polymer matrix, a liquid crystal quadrangle formed in a dispersion form in the polymer matrix, Wherein the first resin layer is formed on the upper substrate, and the second resin layer is formed on the second substrate, Disclosed is a polymer dispersed liquid crystal display device in which a resin layer is formed on the upper substrate or the lower substrate.

2 is a cross-sectional view illustrating the configuration of a power supply terminal of a polymer dispersed liquid crystal display device according to the present invention.

As shown in Fig. 2, the power supply terminal of the polymer dispersed liquid crystal display device according to the present invention includes a pair of thin film plastic films 100, a pair of thin film plastic films 100 And a polymer dispersed liquid crystal 300 provided between the ITO or conductive mesh 200 and the pair of ITO or conductive mesh 200 as the power supply terminal of the polymer dispersed liquid crystal display device 10, A cutting portion 110 in which a portion of any one of the pair of thin film plastic films 100 is cut to expose a portion of any one of the pair of ITO or conductive mesh 200 is formed on the flexible printed circuit board 400 And a step 430 formed to expose the conductive power supply unit 410. The ITO or conductive mesh 430 may be formed by joining the cutting unit 110 and the step 430, (200) Can.

The present invention cuts the upper non-conductive region of a conductive film, rather than cutting a conventional conductive film and a part of a polymer-dispersed liquid crystal, to connect the power source by directly forming terminals on the ITO or conductive film region.

That is, unlike the prior art in which the upper plastic film, the upper ITO and the polymer dispersed liquid crystal are cut and the power is supplied, the ITO or the conductive mesh 200 is exposed by cutting only one plastic film 100 , The manufacturing process of the polymer dispersed liquid crystal display device can be simplified.

In the present invention, the ITO or the conductive mesh 200 is formed by directly coating ITO on a thin plastic film 100 or by closely contacting an ITO film. A polymer dispersed liquid crystal is coated, applied and sealed between the ITO coated surface of the pair of conductive films or the conductive surface of the ITO film bonded surface to form a polymer dispersed liquid crystal display panel 10.

The conductive tape 500 is provided on the ITO or conductive mesh 200 exposed at the cutting portion 110 so that the cutting portion 110 and the step portion 430 are bonded to each other by an adhesive.

The conductive tape or film 500 includes an adhesive containing a conductive material and closely contacts the conductive power supply unit 410 provided on the flexible printed circuit board 400 to perform power supply. In the above description, the conductive tape or film 500 has been described. However, the present invention is not limited thereto. The conductive tape or the conductive mesh 200 may be coated or coated on the exposed ITO or conductive mesh 200 using a paste.

In the present invention, the power supply terminal includes a terminal of the polymer dispersed liquid crystal display device 10 and a power connection terminal of the flexible printed circuit board, and the connection between the polymer dispersed liquid crystal display device 10 and the flexible printed circuit board 400 The method is bonded by a conductive adhesive agent, and the adhesive agent contains a conductive powder which is any one of gold, silver, copper, carbon, nickel and graphene or a mixture thereof, and the organic solvent and additives are added to form a paste Pastes, tapes, and films can be applied to mixed adhesives.

As the conductive coating material, there can be used a conductive coating material which is prepared by uniformly mixing and dispersing silver powder having excellent conductivity in an acrylic resin so as to work in a liquid state having a relatively low viscosity.

Further, as the anisotropic conductive adhesive, an anisotropic conductive adhesive having electrical conductivity in the thickness direction and electric heat anisotropy in the single direction can be applied. The paste type can be formed by screen printing to form the adhesive film according to the shape of the connecting portion. The tape type can be heat-pressed with a film of a thin film to easily connect the circuit .

Depending on the type of the adhesive, various methods such as pressure, heat, ultrasound, UV, room temperature curing, and the like can be used as the bonding method.
