CROSS-RELATION TO OTHER APPLICATIONS [0001] None
FIELD OF THE INVENTION [0002] The present disclosure relates to an electrical contact assembly for supplying electrical power to electroluminescent displays provided on a surface of an object.
BACKGROUND OF THE INVENTION [0003] Electroluminescent display is known for many decades. In an electroluminescent display a phosphor layer is sandwiched between two electrode layers, where at least one of the electrode layer is transparent. Supplying AC (alternating current) power to the electroluminescent display causes light emission from the phosphor layer. Typically, a high AC voltage (> 50 volt) is needed to switch on the electroluminescent display. Use of printing methods to produce the electroluminescent display is driving novel applications of the electroluminescent display. Now the electroluminescent display can be printed on any surface by the use of different printing methods e.g. screen printing, offset, gravure, inkjet, flexography etc. The electroluminescent display can directly be printed on a surface of an object or can be printed on a sheet and then the sheet can be applied on a surface of the object. In a non-limiting example, the object can be a package. In a non-limiting example, the object can be made of paper, plastic, glass, metal wood, ceramic etc. In order to switch on the electroluminescent display, a battery and an inverter circuit (DC-to-AC converter or AC-to-AC inverter) is need. Fixing the battery and the inverter circuit on the surface of the object is a complicated process and also the aesthetic of the object can be destroyed as the battery and the inverter circuit are thick (> 2mm). The battery and the inverter circuit also increase the total weight of the object. Different types of electrical contact assemblies have been reported in US patent no. 6124672 and in US application No. 11/266435. In order to make the electroluminescent display a common technology, a simple electrical contact assembly is needed that can power the electroluminescent display provided on a surface of an object. Simultaneously, the object can easily be removed and can easily be inserted into the electrical contact assembly while maintaining the safety of the users.
-1SUMMARY OF THE INVENTION [0004] The present invention relates to an electrical contact assembly to supply electrical power to electroluminescent displays. The electroluminescent displays are provided on a surface of an object. The electrical power is supplied to the electroluminescent displays by at least two conducting layers disposed on an outer surface of the object. The electrical contact assembly comprises a slot in a housing for inserting a portion of the object along with the at least two conducting layers. The slot is defined by at least one wall and a bottom. At least two ball casings are provided in the housing, wherein each ball casing is connected to the slot through an opening at the at least one wall. Each ball casing comprises an elastically movable electrical contact terminal diagonally opposite to the opening. A conducting ball is provided in each ball casing such that a first portion of the conducting ball is projecting through the opening into the slot and touching one of the at least two conducting layers and a second portion of the conducting ball is touching the elastically movable electrical contact terminal. A power controlling circuit is provided in the housing and is electrically connected to each of the elastically movable electrical terminal to supply electrical power to at least one electroluminescent display. The electrical contact assembly facilitates easy removal and insertion of the object into/from the slot.

[00013] The present invention is about an electrical assembly system to supply AC electrical power to at least one electroluminescent display. Fig. 1 shows an object 110 with at least one electroluminescent display 112 and a plurality of conducting layers 113. The object can be anything made of, but not limited to, plastic, paper, cardboard, corrugated paper, glass, ceramic, wood etc. In a non-limiting example, the object 110 is a package. In another non-limiting example, the object 110 is a decoration item e.g. glass vial, picture frame. The electroluminescent display 112 is provided on an inner or on an outer surface of the object 110. The electroluminescent display 112 is electrically connected to the conducting layers 113 through conducting traces 114, provided on the object 110. In a non-limiting example, the electroluminescent displays 112, the conducting layers 113 and the conducting traces 114 are provided directly on the surface of the object 110, by using a printing method. In another nonlimiting example, the electroluminescent displays 112, the conducting layers 113 and the conducting traces 114 are first printed on a sheet of plastic or paper and then the sheet is fixed on the surface of the object 112, like a label.
[00014] Fig. 2 shows an electrical contact assembly 200 to switch on the electroluminescent displays 212. In the electrical contact assembly 200, the object 210 is inserted into a slot 230 of a housing 220. The electroluminescent displays 212 are provided on a surface of the object 210. The outer surface 211 of the object 210 comprises at least two conducting layers 213. The conducting layers 213 are connected to the electroluminescent displays 212 through conducting
-4traces 214, provided on the object 210. The housing 220 also comprises a power controlling circuit to supply electrical power to the electroluminescent displays 212 through the conducting layers 213.
[00015] Fig. 3A shows a cross sectional view of the electrical contact assembly 300 along the plane YZ of the Fig. 2. The electroluminescent displays 312 are provided on an object 310. Conducting layers 313 are provided on an outer surface 311 of the object 310. The conducting layers 313 are connected to the electroluminescent displays 312 through conducting traces. A portion of the object 310 is inserted into a slot 330 of a housing 320. The object 310 is inserted into the slot 330 in such a way that some portion of the conducting layers 313 are also inside the slot 330. The housing 320 is mainly made of an electrically insulating material. In a nonlimiting aspect, the housing material is plastic, paper, wood, ceramic, glass. The slot 330 is defined by at least one wall 331 and by a bottom 332. The perimeter of the slot 330, defined by the at least one wall 331 is larger than the perimeter of the portion of the object 310 that is inside the slot 330 so that the object 310 can be easily inserted and removed from the slot 330. The housing 320 further comprises at least two ball casing 340. Each of the ball casing 340 comprises a conducting ball 350 and an elastically movable electrical contact terminal 360. Each of the ball casing 340 is connected to the slot 330 through an opening 341 such that some portion (here called a first portion 351) of the conducting ball 350 is projecting through the opening 341 into the slot 330 and touching one of the conducting layers 313. The diameter of the opening 341 is less than the diameter of the conducting ball 350 so that the conducting ball 350 is retained always inside the ball casing 340. In a non-limiting aspect, the conducting ball is a metallic sphere of a diameter less than 2 cm. In another non-limiting aspect, the conducting ball is a plastic ball coated with a metallic and conducting coatings. The elastically movable electrical contact terminal 360 is provided diagonally opposite to the opening 341 such that some portion (here called a second portion 352) of the conducting ball 350 is touching the elastically movable electrical contact terminal 360. The purpose of the elastically movable electrical contact terminal 360 is to electrically connect the conducting ball 350 to a power controlling circuit 370. The power controlling circuit 370 is also placed in the housing 320. In a non-limiting aspect, the power controlling circuit 370 comprises a DC-to-AC inverter and batteries. In another non-limiting aspect, the power controlling circuit 370 comprises a AC-toAC inverter circuit. The elastically movable electrical contact terminal 360 also provides smooth movement of the conducting ball 350 inside the ball casing 340. When the object 310 is inserted into the slot 330, the conducting balls 350 slightly move inward. This way the object
-5310 can easily be inserted into the slot 330 and can easily be removed from the slot 330. The smooth movement of the conducting ball 350 does not damage or scratch the conducting layers 313.
[00016] Fig. 3A and Fig. 3B show two different embodiments of the electrical contact assembly 300, which have two different types of elastically movable electrical contact terminal 360. In Fig. 3A the elastically movable electrical contact terminal 360 comprises an electrical contact terminal 362 and an elastic material 361. In a non-limiting example, the electrical contact terminal 362 is a piece of metal sheet. In another non-limiting example, the electrical contact terminal 362 is selected from a group of metal tape, metal wire and conducting layer deposited on plastic or paper. One surface of the electrical contact terminal 362, here called a front surface, is touching the second portion 352 of the conducting ball 350. On a back surface, that is opposite to the front surface, of the electrical contact terminal 362 is provided the elastic material 361 so that the electrical contact terminal 362 can be compressed by the conducting ball 350. In a non-limiting example, the elastic material 361 is made of foam or rubber or spring. The electrical contact terminal 362 is electrically connected to the power controlling circuit 370 through a conducting material 365. The conducting material 365 can be, but not limited to, a metal wire.
[00017] In Fig. 3B the elastically movable electrical contact terminal 360 comprises an electrical contact terminal 362 and a conducting spring 364. In a non-limiting example, the electrical contact terminal 362 is a piece of metal sheet. In another non-limiting example, the electrical contact terminal 362 is selected from a group of metal tape, metal wire and conducting layer deposited on plastic or paper. One surface of the electrical contact terminal 362, here called a front surface, is touching one end (364a) of the conducting spring 364. The other end (364b) of the conducting spring 364 is touching the second portion 352 of the conducting ball 350. In a non-limiting aspect, the conducting spring 364 is made of metal. The electrical contact terminal 362 is electrically connected to the power controlling circuit 370 through a conducting material 365. The conducting material 365 can be, but not limited to, a metal wire.
[00018] Fig. 3C shows a cross sectional view of the electrical contact assembly 300 along the plane XZ of the Fig 2. A part of the at least one wall 331 of the slot 330 can be seen in Fig. 3C. Openings 341 and the conducting balls 350 can be also seen.
-6[00019] The electrical contact assembly 300 further comprises a switch 380, as shown in Fig. 3A and Fig. 3B. The switch 380 is provided on the bottom 332 of the slot 330. The switch 380 is electrically connected to the power controlling circuit 370. The purpose of the switch 380 is to supply electrical power from the power controlling circuit 370 to the conducting ball 350 only when the object 310 is inserted into the slot 330. If the object 310 is removed from the slot 330, the switch 380 switches off the power supply to the conducting ball 350. This way safety of the electrical contact assembly 300 is ensured. If somebody touches the conducting ball 350 by fingers, he/she will not get an electrical shock. The switch 380 comprises a first conductor 381 and a second conductor 382 provided on the bottom 332 and separated by a gab 385. The first conductor 381 and the second conductor 382 can be printed conducting traces on a plastic or a paper substrate. The first conductor 381 and the second conductor 382 are electrically coupled with the power controlling circuit 370. An elastic boundary 384 is provided at the bottom 332 and around the first conductor 381 and the second conductor 382. The elastic boundary 384 can be made of foam or rubber or any other elastic material. A third conductor 383 is provided on top of the elastic boundary 384 such that when the object 310 is placed in the slot 330, the elastic boundary 384 is compressed and the third conductor 383 touches the first conductor 381 and the second conductor 382 and hence switches on the switch 380. The third conductor 383 can be a conducting layer deposited on a piece of paper or plastic. Any other switch, available in prior-art can also be used here.
[00020] Fig. 4A and Fig. 4B shows another embodiment of the electrical contact assembly 400 for electroluminescent displays. Electroluminescent displays 412 are provided on the outer surface 411 of a bottle 410. The bottle 410 is an object here and it can be made of plastic or glass. The electroluminescent displays 412 is connected to a plurality of conducting layers 413 through conducting traces 414. Fig. 4B shows the complete electrical assembly 400 which comprises the bottle 410 and the housing 420. Once the bottle is inserted into the slot of the housing 420, electroluminescent displays 412 switches on.
