Abstract
Description
- The present invention relates to liquid crystal panels and methods for fabricating these panels; and particularly to a liquid crystal panel including a sealant having conductive beads mixed therein, and a method for fabricating such liquid crystal panel.
- A liquid crystal display (LCD) is capable of displaying a clear and sharp image through thousands or even millions of pixels that make up the complete image. The liquid crystal display has thus been applied to various electronic equipment in which messages or pictures need to be displayed, such as mobile phones and notebook computers. The liquid crystal display generally includes a liquid crystal panel for displaying images, and a backlight for illuminating the liquid crystal panel.
- Referring to
FIG. 5 , a typicalliquid crystal panel 1 includes a thin film transistor (TFT)substrate 11, a color filter (CF)substrate 13 opposite to theTFT substrate 11, aliquid crystal layer 15 sandwiched between the twosubstrates conductive adhesive 16, and asealant 17. - The
sealant 17 is applied at a periphery of theTFT substrate 1, and is sandwiched between the twosubstrates substrates sealant 17 cooperatively define a space for accommodating theliquid crystal layer 15. Theconductive adhesive 16 is applied at an outside of thesealant 17, and electrically connects the twosubstrates conductive adhesive 16 is generally applied in the form of discrete beads. The beads include at least one silver-based compound, which includes silver ions. The silver-based compound can for example be silver nitrate (AgNO3). - A method of fabricating the
liquid crystal panel 1 generally includes: applying thesealant 17 at a periphery of theTFT substrate 11, thereby defining a space; distributing spacers (not shown) on theTFT substrate 11, and filling liquid crystal material in the space; applying theconductive adhesive 16 to the outside of thesealant 17; and in a vacuum environment, attaching theCF substrate 13 onto theTFT substrate 11 to form theliquid crystal panel 1. - In the process of fabricating the
liquid crystal panel 1, a height of thesealant 17 is a factor that can influence the quality of the display provided by theliquid crystal panel 1 in use. In particular, when thesealant 17 has a uniform height, this helps ensure the liquid crystal material has a uniform thickness between the twosubstrates conductive adhesive 16 is applied at the outside of thesealant 17, the uniformity of the height of thesealant 17 may be diminished. Thereby, the display quality of theliquid crystal panel 1 may be impaired. - One way to overcome the above-described problems is to reduce the sizes of the beads of the
conductive adhesive 16. If this is done, a proportion of the silver-based compound mixed in theconductive adhesive 16 needs to be increased, in order to maintain good electrical conductivity of theconductive adhesive 16. However, in general, it is difficult to properly mix a high proportion of the silver-based compound in theconductive adhesive 16. Furthermore, when theconductive adhesive 16 has a high proportion of silver-based compound, the step of applying theconductive adhesive 16 on theTFT substrate 11 can be problematic. - Therefore, a new liquid crystal panel that can overcome the above-described problems is desired. A method for fabricating such a liquid crystal panel is also desired.
- In one preferred embodiment, a liquid crystal panel includes a first substrate, a second substrate opposite to the first substrate, a liquid crystal layer sandwiched between the first and second substrates, and a sealant provided at the first mother substrate and attaching the first and second substrates together. The sealant has a plurality of conductive beads mixed therein. The conductive beads electrically interconnect the first substrate and the second substrate.
- In another preferred embodiment, a method for fabricating a liquid crystal panel includes: providing a first substrate; mixing a plurality of conductive beads into a sealant; applying the sealant having the plurality of conductive beads at a periphery of the first substrate, thereby defining an accommodating space; dropping liquid crystal material into the accommodating space, thereby forming a liquid crystal layer; providing a second substrate, and attaching the second substrate onto the first substrate such that at least a plurality of the plurality of conductive beads in the sealant electrically interconnect the first and second substrates; and curing the sealant.
- Other novel features and advantages will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings. In the drawings, all the views are schematic.
-
FIG. 1 is an exploded, isometric, abbreviated view of a liquid crystal panel according to a first embodiment of the present invention, the liquid crystal panel including a sealant (partly cut away), the sealant including a plurality of conductive beads. -
FIG. 2 is an enlarged, isometric view of one of the conductive beads ofFIG. 1 , with part of the conductive bead cut out. -
FIG. 3 is a flowchart summarizing an exemplary method for fabricating the liquid crystal panel ofFIG. 1 . -
FIG. 4 is an isometric view of one of conductive beads of a liquid crystal panel according to a second embodiment of the present invention, with part of the conductive bead cut out. -
FIG. 5 is an exploded, isometric view of a conventional liquid crystal panel. - Referring to
FIG. 1 , aliquid crystal panel 2 according to a first embodiment of the present invention is shown. Theliquid crystal panel 2 includes afirst substrate 21, asecond substrate 23 opposite to thefirst substrate 21, aliquid crystal layer 25 sandwiched between the first andsecond substrates sealant 27. - The
first substrate 21 is a thin film transistor (TFT) substrate, and includes a plurality ofpixel electrodes 211 and a plurality ofcommon electrodes 213. Thesecond substrate 23 is a color filter (CF) substrate, and includes a transparentconductive layer 231. Thesealant 27 is applied at a periphery of thefirst substrate 21, and is sandwiched between the first andsecond substrates substrates sealant 27 cooperatively define a space therebetween, for accommodating theliquid crystal layer 25. Thesealant 27 can be ultraviolet-curable sealant or heat-curable sealant or a combination of these, and includes a plurality of generally sphericalconductive beads 270 mixed therein. - Referring also to
FIG. 2 , each of theconductive beads 270 includes acore 271, and aconductive layer 272 substantially covering a surface of thecore 271. Thecore 271 is generally made from silicate, but can be made from other material such as fiberglass. Theconductive layer 272 is made from at least one material selected from the group consisting of silver, tin, lead, gold, copper, nickel, and aluminum; and is formed by an electroplating method or a coating method. - The
conductive beads 270 mixed in thesealant 27 can electrically connect thecommon electrode 213 of thefirst substrate 21 with the transparentconductive layer 231 of thesecond substrate 23. Good electrical conductivity can be achieved by configuring a distribution density of theconductive beads 270 appropriately. Preferably, a proportion by weight of theconductive beads 270 relative to thesealant 27 is in the range from 0.5%˜5%. For example, the proportion by weight of theconductive beads 270 relative to thesealant 27 can be 1%. - Referring to
FIG. 3 , a method for fabricating theliquid crystal panel 2 includes: step S1, providing thefirst substrate 21 and forming thesealant 27 having theconductive beads 270 mixed therein; step S2, forming theliquid crystal layer 25; step S3, providing thesecond substrate 23 and attaching the first andsecond substrates sealant 27. - In step S1, the
first substrate 21 is provided. Theconductive beads 270 are mixed into thesealant 27. Thesealant 27 having theconductive beads 270 is applied at a periphery of thefirst substrate 21 by a printing method or a coating method. Thereby, an accommodating space for receiving theliquid crystal layer 25 is defined. The accommodating space has a top opening. - In step S2, the
liquid crystal layer 25 is formed. A plurality of spacers (not shown) are distributed in the accommodating space. Liquid crystal material (not shown) is then dropped into the accommodating space. - In step S3, the
second substrate 23 is provided, and the first andsecond substrates second substrate 23 is first loosely attached onto thefirst substrate 21, and is then pressed. Thereby, thecommon electrode 213 of thefirst substrate 21 is electrically connected with the transparentconductive layer 231 of thesecond substrate 23 via theconductive beads 270 that are mixed in thesealant 27. - In step S4, the
sealant 270 is cured, thereby forming theliquid crystal panel 2. - In summary, because the
conductive beads 270 are mixed in thesealant 27, theconductive beads 270 do not influence a uniformity of a height of thesealant 27. Therefore, theliquid crystal panel 2 can provide a good quality display. Furthermore, the process of mixing theconductive beads 270 in thesealant 27 is simpler than a conventional process of applying conductive beads onto an outside of a sealant. Thus, the method for fabricating theliquid crystal panel 2 is simplified, and theliquid crystal panel 2 can have a reduced cost. - Referring to
FIG. 4 , aconductive bead 370 of a liquid crystal panel according to a second embodiment of the present invention is similar to theconductive bead 270 of the first embodiment. However, theconductive bead 370 includes a generallycylindrical core 371, and aconductive layer 372 substantially covering a surface of thecore 371. Thecore 371 is generally made from fiberglass, but can be made from other material such as silicate. Theconductive layer 372 is made from at least one material selected from the group consisting of silver, tin, lead, gold, copper, nickel, and aluminum; and is formed by an electroplating method or a coating method. - It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the invention.
