Description

ACTIVE LABELS FOR GARMENTS

FIELD OF THE INVENTION

The present invention relates generally to the field of labels and tags

for garments and more particularly to electronic labels for garments.

BACKGROUND OF THE INVENTION

It is typical for the manufacturer of a garment to affix a label to the

garment which bears the manufacturer's brand name or logo. Labels are also

used to describe the material contents of a garment, to give care instructions,

or to display manufacturer information such as the manufacturer's RIN

number. Because labels are typically small, they can carry only a limited

amount of information. Therefore, it is not at all uncommon to find two or

more labels affixed to different locations of a single garment. For example, a

shirt may carry a brand label which is placed in a visible location, and a neck

label to give product information. However, there is a small, finite limit to the

number of labels which can be applied to a garment without cluttering the

garment.

Another problem with conventional labels for garments is that only

static designs and information can be contained in the label. Animated

designs and logos are not possible with conventional woven, printed or

stamped labels. Also, conventional labels cannot display information which

may change over time. SUMMARY OF THE INVENTION

The present invention is an active label which is characterized by a

changeable display. The label includes a thin, flexible LCD panel on which

various types of label information can be displayed. The LCD panel is

contained in a water-tight encasement made from an elastomeric material

which can be affixed to a garment. The preferred method of attachment is by

sewing the label to the garment. Alternately, the label can be attached to

garments by metal or plastic rivets, VELCRO-type fasteners, bartacks,

adhesives, snaps, or any other attachment technique known in the garment

manufacturing business.

The label information which is displayed can include a company name

and/or logo, material content information, care instructions, manufacturer

information, e-mail address, web page address, telephone numbers or other

information which the manufacturer wants to include on the label. This

information can be included in multiple screen images which can be

advanced by pressing a button or touch-sensitive input on the display. Also,

information which changes over time can be displayed.

The active label of the present invention obviates the need for placing

multiple labels on garments as is the current practice. Moreover, the active

label of the present invention can display animated logos or changing

information which is not possible with current labels. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE DRAWINGS

Referring now to the drawings, and particularly to Figure 1 , an active

label for garments or other clothing articles is shown and indicated generally

by the numeral 10. The active label includes an electronic display 20 for

displaying label information and a case 40. Preferably, both the electronic

display 20 and case 40 are flexible. The label information may consist simply

of a brand name or logo which identifies the source or origin of the garment.

The label information may also include product information such as the

material content of the garment and care instructions or manufacturer

information. The electronic display 20 is preferably a liquid crystal-type display.

The display 20 comprises a display panel 22, a backlight panel 28 to backlight

the display panel 22, and a circuit board 30 containing an integrated circuit

which provides power, data, and control signals for operating the display 20.

The display panel 22 is, as already mentioned, a liquid crystal-type display

which comprises liquid crystal composites disposed between upper and lower

substrates. Display elements are formed by etching a conductive film deposit

on the inner surface of each substrate. Etched areas become the display

background; unetched areas become the display elements. When a voltage

potential is applied, the display elements becomes visible. The display

elements can be individually addressed (i.e. their conductive surfaces

energized) to selectively activate the display elements. The display panel

may be either a monochrome display or a color display. Also, the display

panel could be a passive matrix or active matrix display.

Numerous types of LCD panels can be used in connection with the

present invention including reflective, transmissive, or transflective panels.

However, transflective LCD's are best suited for practicing the present

invention because the display elements are visible in a wide variety of lighting

conditions including both outdoor and indoor lighting conditions. Transflective

displays include a backlighting panel 28 to backlight the display panel 22.

Light-emitting diodes (LEDs) 28 provide a light source which is transmitted by

the backlight panel 28 which serves as a light guide. An electroluminescent

panel could also be used as a backlight for the display panel 22. LED

backlighting is preferred, however, because of its longevity. The backlight

4 28a can be manually activated and deactivated by an illumination button 50

(see Fig. 3) on the label 10. Alternatively, the backlight can be activated by a

touch-sensitive input (i.e. touch screen) on the display panel 22.

The circuit board 30 contains ail of the circuitry necessary to drive the

display panel 22. The circuit board contains an integrated circuit which

includes a microprocessor 32, display driver 34 and power supply 36. The

circuit board 30 includes a series of terminals 38 which are electrically

connected to corresponding terminals (not shown) on the display panel 22.

Such connection may be made for example by means of a conventional

zebra-strip or similar conductive element. In certain cases, it may be

necessary to locate the microprocessor 32 and driver circuits 34 remotely

from the display panel 22. In these cases, the microprocessor 32 and driver

circuit 34 can be connected to the display panel 22 by a conventional flex

connector which is disposed between two-layers of the garment. The

advantage of locating the circuit components remotely from the display panel

22 lies in the reduction of the size of label 20 making it possible to keep the

label 10 thin. The construction of LCD's is well-known to those skilled in the

art and therefore will not be described in detail herein.

The case 40 comprises a base panel 42 and a window frame 44 which

has a transparent window 46 for viewing the display 20. Both the base panel

42 and window frame 44 are preferably made of an elastomeric material such

a flexible, sewable rubber. During assembly, the display 20 is interposed

between the base panel 42 and window frame 44. The window frame 44 is

then glued or bonded to the base panel 42 to form a water-tight enclosure. The base panel 42 is larger than the window frame 44 so that a peripheral

portion 48 of the base panel 42 extends outward from the window frame 44

on all sides. The perimeter portion 48 of the base panel 42 provides a

convenient location for stitching to secure the label 10 to a garment.

Referring now to Figure 3, there is shown a front view of an active label

constructed in accordance with the present invention. The label 10 shown in

Figure 3 has a generally square configuration. This embodiment uses only a

single screen image for displaying a company logo and product information.

An illumination button 50 is disposed along the bottom of the display panel 22

to provide a means to turn the backlighting on and off.

Figure 4 shows another embodiment of the active label 10 which

includes multiple screen images and a button 50. The company's logo is

displayed in the upper left corner of each of the display screens. The bottom

half of the display 20 is used to display information such as the material

content of the garment, care instructions, manufacturer information, e-mail

address, telephone numbers, or other information which the manufacturer

wants to include on the label. A button 50 is disposed along the bottom of the

display to advance the screen image and to turn the backlighting on and off.

The button 50 is preferably a two-way toggle button. Pressing the left side of

the toggle button 50 advances the screen image. Pressing the right side

turns the backlighting on and off.

Figure 5 shows a third embodiment of the active label 10. In this

embodiment, the display has an elongated, rectangular shape. The larger

area on the left is an information screen on which the label information is displayed. The smaller area on the right where the company logo is

displayed is a touch screen 52. The touch screen 52 includes two touch

sensitive areas indicated by the triangular pointers. The left pointer advances

the display screen. The right pointer turns the backlighting on and off.

Figure 6 shows a fourth embodiment of the active label 10. In this

embodiment, the label has a vertically oriented, rectangular configuration.

The upper portion of the rectangle contains one or more solar cells 54 which

can be used to power the display and/or recharge the display batteries. The

lower portion of the label where the company logo is displayed is a touch

screen 52. The middle portion of the label is an information screen. As in the

previous embodiment, the touch screen can be used to advance the screen

image and to turn the backlighting on and off.

In all of the embodiments described thus far, the label is designed to

be sewn onto the garment. The precise location of the label will depend on

the type of garment. In shirts, the label would typically be attached to the top

edge of a shirt pocket or to the chest area. In pants, the label would typically

be attached to a pocket or along the waistline.

Other methods of attaching the label 10 to the garment may also be

used. For example, the label 10 may be secured by hooks, buckles, snaps,

VELCRO-type fasteners, adhesives, or pins. The label 10 could also be

designed as a cartridge which slides in a pocket on the garment. Any

attachment technique known in the garment industry could be used.

The present invention overcomes the problems associated with

conventional woven or printed labels. Since the label can be programmed to display multiple screen images, only a single label is needed. Thus, the

present invention provides a method to convey more information to

consumers without cluttering the garment with labels. Also, the label can be

easily programmed to automatically display a sequence of related images to

provide an animated logo rather than a static logo.

The present invention may, of course, be carried out in other specific

ways than those herein set forth without departing from the spirit and essential

characteristics of the invention. The present embodiments are, therefore, to be

considered in all respects as illustrative and not restrictive, and all changes

coming within the meaning and equivalency range of the appended claims are

intended to be embraced therein.
