Description

FIELD OF THE INVENTION

The invention relates to systems permitting advertisers to target geographical regions and demographic groups with ever changing, current advertising content without incurring the high fixed cost of traditional single-message billboards. More particularly, the invention relates to a system and method permitting commercial advertisers, such as consumer product companies and the advertising agents that represent them, to directly access a network of thousands of large, high resolution electronic displays located in high traffic areas and to directly send their own advertisements electronically to the network to be displayed at locations and times selected by the advertiser.

BACKGROUND OF THE INVENTION

Consumer product advertising takes many forms, such as television commercials, newspaper and magazine advertisements, mailings, point-of-sale displays, outdoor billboards, etc. Using current advertising media, advertisers engage in a constant struggle to efficiently use their budgets to most effectively reach their geographic and demographic targets.

Focusing on the outdoor advertising component of advertising by consumer product companies, it is well known that outdoor billboards have traditionally taken the form of single-message displays formed of printed sheets or painted surfaces containing the advertising content adhered to a flat backing. This time-honored outdoor advertising technique has remained essentially unchanged throughout the twentieth century. The high cost of printing, transporting and mounting a message on a conventional billboard has dictated that the same message remain in place for a considerable period of time. Thus, a conventional billboard cannot be readily changed to reflect current events within the geographic area of the billboard. Additionally, the content on a conventional billboard tends to become essentially “invisible” as a part of the landscape after its content has been in place for a relatively short period of time, especially to commuters and others who regularly pass the billboard. Beyond the above problems with cost, single-message content, lack of content changeover capability, and the like, conventional outdoor billboards have come under increasing criticism because in their large numbers, and often tattered condition, they clutter highways with a distasteful form of visual “pollution”. A reduction in the number of billboards and improvement of the appearance of those that remain, if accomplished while increasing the overall advertising impact afforded by outdoor advertising, would please virtually everyone.

The use of electronic billboards has been suggested, for example, in U.S. Pat. No. 5,612,741. However, there is no electronic billboard network in operation whereby commercial advertisers may directly place ads onto selected billboards at selected times through direct access to a master network. Such a network, properly designed and operated, promises to overcome the numerous disadvantages currently associated with the outdoor advertising industry, while also meeting the above-enumerated needs of consumer products advertisers.

SUMMARY OF THE INVENTION

According to the present invention, commercial advertisers, such as consumer product companies and the advertising agents that represent them, directly access a network of multiple large, high resolution electronic displays located in high traffic areas and directly send their own advertisements electronically to the network to be displayed at locations and times selected by the advertisers. In preferred embodiments, the system of the invention includes a central information processing center that permits customers to review a schedule of times and electronic display locations that are available for placement of advertisements, and also permits customers to purchase available times at selected electronic display locations for placement of their advertising content. The customer then transmits his video or still image advertising content to the processing center where the content is reviewed for appropriateness and then transmitted to the customer-selected electronic display(s). The electronic displays preferably are large (e.g., 23×33½ ft.) flat LED displays that are driven by their own video or image servers. Verification that the advertisements run as ordered is facilitated by an information storage module or, more preferably, by a digital camera or series of digital cameras. A traffic counter may be used to determine the traffic that passed by the display while the advertisement was running. Bills and reports containing market and demographic analysis are generated and sent to the customer.

BRIEF DESCRIPTION OF THE DRAWINGS

Some of the features of the invention having been stated, other features will appear as the description proceeds, when taken in connection with the accompanying drawings, in which

FIG. 1 is a block diagram showing the principal components of an electronic display network constructed in accordance with the present invention.

FIG. 2 is a view of one of the electronic displays of the network of FIG. 1 .

DETAILED DESCRIPTION OF THE INVENTION

While the present invention will be described more fully hereinafter with reference to the accompanying drawings, in which aspects of the preferred manner of practicing the present invention are shown, it is to be understood at the outset of the description which follows that persons of skill in the appropriate arts may modify the invention herein described while still achieving the favorable results of this invention. Accordingly, the description which follows is to be understood as being a broad, teaching disclosure directed to persons of skill in the appropriate arts, and not as limiting upon the present invention.

Referring to the drawings, and particularly to FIG. 1 , there is shown a block diagram of a system 20 for direct placement of commercial advertisements, public service announcements and other content on electronic displays. System 20 includes a network comprising a plurality of electronic displays 30 that are located in high traffic areas in various geographic locations. The displays may be located in areas of high vehicular traffic, and also at indoor and outdoor locations of high pedestrian traffic, as well as in movie theaters, restaurants, sports arenas, casinos or other suitable locations. Thousands of displays, up to 10,000 or more displays worldwide, may be networked according to the present invention. In preferred embodiments, each display is a large (for example, 23 feet by 33½ feet), high resolution, full color display that provides brilliant light emission from a flat panel screen.

A customer of system 20 , for example an in-house or agency representative of a consumer products company, may access a central information processing station of the system via the Internet through a Customer Interface Web Server 40 . The customer interface web server has a commerce engine and permits the customer to obtain and enter security code and billing code information into a Network Security Router/Access module 50 . Alternatively, high usage customers of the system may utilize a high speed dedicated connection to module 50 . Following access, the customer reviews available advertising time/locations through a Review Schedule and Purchase Time module 60 that permits the customer to see what time is available on any display throughout the world and thereafter schedule and purchase the desired advertising time slot. Next, the customer transmits the advertising content on-line through the Internet, a direct phone line or a high speed connection (for example, ISDN or DSL) for receipt by the system's Video & Still Image Review and Input module 70 . In parallel, the system operator may provide public service announcements and other content to module 70 . All content, whether still image or video, is formatted in NTSC, PAL, SECAM, YUV, YC, VGA or other suitable formats.

The video & still image review and input module 70 permits a system security employee to conduct a content review to assure that all content meets the security and appropriateness standards established by the system, prior to the content being read to the server 100 associated with each display 30 where the content being transmitted to the server 100 will be displayed. Preferably, the servers are located at their respective displays and each has a backup. An example of a suitable server is the IBM RISC 6000 server.

The means for transmitting content information to the display locations may take a number of forms, with it being understood that any form, or combination thereof, may be utilized at various locations within the network. As shown in FIG. 1 , the means include:

a. High speed cable

b. Satellite

c. Dedicated phone

d. High speed line (e.g., ISDN)

e. Cellular or PCS

f. Internet

g. Radio/radio pulse transmission

h. High speed optical fiber.

A video converter/scaler function and a video controller function provided by module 110 may be utilized in connection with those servers 100 and associated displays 30 that require them, according to data transmission practices well known in the art.

Verification that advertisements do, in fact, run at the intended time at the intended displays may be provided by an information storage module (not shown) linked to each display. Another form of verification may be achieved by a Digital Camera and Traffic Count Recorder 120 that continuously records the content appearing at its respective display 30 and digitally transmits video verification information to a Verification Archives module 150 . Recorder 120 also provides traffic count information (for example, 225 vehicles passed the display while an advertisement ran) to verification archives module 150 .

Information from verification archives module 150 is utilized by a demographic analysis module 160 and a market analysis module 170 to generate information for reports to be sent to customers after their advertisements run. To this end, analysis data from modules 160 and 170 is transmitted to a Billing and Report Generation module 190 where reports are assembled showing, for example, the time of the advertisement, the content of the advertisement, the traffic count and residence/median income information about those who saw the advertisement. A representative, simplified report for an advertisement running on a single display is as follows:

Module 190 also produces bills that may be transmitted by phone lines for a debit payment such as a direct bank draft, or other suitable payment mode.

Referring to FIG. 2 , there is shown a pictorial view of one preferred form for the electronic displays 30 . In this embodiment, display 30 takes the form of a 23 feet by 33½ feet seamless flat screen display including multiple flat panel display modules. The panels utilize advanced semiconductor technology to provide high resolution, full color images utilizing light emitting diodes (LED's) with very high optical power (1.5-10 milliwatts or greater) that are aligned in an integrated array with each pixel having a red, green and blue LED. It will be appreciated that multiple LED's of a given color may be used at pixels to produce the desired light output; for example, three 1.5 milliwatt blue LED's may be used to produce a 4.5 milliwatt blue light output. Each red, green and blue emitter is accessed with 24 bit resolution, providing 16.7 million colors for every pixel. An overall display of 23 feet by 33½ feet, so constructed, has a high spatial resolution defined by approximately 172,000 pixels at an optical power that is easily viewable in bright sunlight. Suitable display modules for displays 30 are manufactured by Lighthouse Technologies of Hong Kong, China, under Model No. LV50 that utilize, for blue and green, InGaN LED's fabricated on single crystalline Al 2 O 3 (sapphire) substrates and, for red, superbright AlInGaP LED's fabricated on a suitable substrate such as GaP. These panels have a useful life in excess of 50,000 hours, for example, an expected life under the usage contemplated for network 20 of 150,000 to 200,000 hours and more. In preferred embodiments, the panels are cooled from the back of the displays, preferably via a refrigerant-based air conditioning system (not shown) such as a forced air system or a thermal convection or conduction system. Non refrigerant-based options may be used in locations where they produce satisfactory cooling. The displays preferably have a very wide viewing angle, for example, 160°.

While the Lighthouse Technologies displays utilize the InGaN on sapphire and AlInGaP on GaP LEDIs described above, other materials may be used for the LED's as follows:

1. (Blue/green) InGaN on SiC, preferably with a suitable buffer layer such as AlN

2. (Blue/green) InGaN on GaN

3. (Blue/green) InGaN on AlN, preferably with a suitable buffer layer such as AlN.

It will be appreciated that the InGaN on sapphire and the other solid state LED's described above have substrates with high optical transmissivity and produce very high optical power. This is important for a number of reasons, including giving the electronic display designers the ability to create very wide viewing angles up to approximately 160°, and the resultant increase in visibility of the displays to viewers in oncoming traffic.

In addition to the particular solid state LED's mentioned above, the discrete sources of blue, green and red light at each pixel may take other forms such as composite devices including an ultraviolet LED that is utilized to excite a phosphor that, in turn, produces light of a selected spectrum. The ultraviolet LED may be a GaN on sapphire or GaN on SiC device, preferably with a suitable buffer layer. In one embodiment, ultraviolet LED's are incorporated into three different composite devices, each with a different phosphor for producing blue, green and red, respectively. In another embodiment, a phosphor is selected to produce white light and a desired color is produced by passing the white light through a narrow band pass filter. According to this white-light embodiment, filters of blue, green and red may be used to create discrete composite devices that produce blue, green and red light at each pixel. The use of white light with appropriate narrow band pass filters has the advantage of producing a colored light with an excellent wave length distribution that will not change appreciably over time, a desirable property for color balancing. On the other hand, the use of three different phosphors to directly produce blue, green and red without a filter has the advantage of higher efficiency because light is not filtered out. Both approaches have the advantage of excellent persistence which, as known in the art, is a desirable feature that is especially important in video applications.

It will be appreciated that energy sources other than ultraviolet LED's may be used to excite the phosphors of the composite devices discussed immediately above.

The provision of one or more high resolution, highly aligned digital cameras at each display site, for example the camera or cameras utilized in digital camera and traffic counter 120 , or other specifically dedicated cameras, provides a means permitting diagnostics and calibration of the displays. As known in the art, certain digital cameras have a resolution of over 7,000,000 pixels—as compared to approximately 172,000 pixels on the above-described 23×33½ ft. display. Thus, by directing a digital camera at a display, or directing multiple digital cameras at different discrete portions of a display, a correspondence may be attained where a portion of each digital camera's image corresponds to a single pixel in the display. At selected times set aside for diagnostics and calibration, such as a five minute period each night, the entire display may be run red, then green, then blue, followed by white, all at multiple power levels. In the most basic diagnostic operation carried out when the display is run red/green/blue, the camera(s), mounted at a selected distance from the display such as sixty feet away, are capable of detecting nonfunctioning or excessively degraded LED's for replacement.

Beyond replacing defective LED's, each night the system may automatically re-calibrate all LED's in the display. To this end, the display is run red/green/blue at several iterative power levels (e.g., 20%/40%/60%/80%/100%) and the optical power output of each LED is sensed for each power level, with the goal being to calibrate the system so that each red, green or blue LED has the same optical power output at each power level as do the other LED's of the same color. Calibration is achieved by diode recalibration scaler software that may be associated with the video converter/scaler at 110 (FIG. 1 ). The diode recalibration scaler receives information from the diagnostic equipment indicating the optical power output of each LED at the various power levels and, through an associated automatic calibration LED look-up table, accounts for daily variance in LED output (degradation or increase) by adjusting the power curve by which the LED will be driven the next day.

As an alternative to using digital cameras for the diagnostic function, in other embodiments miniature photodector chips, with or without filters, may be located in close proximity to each LED in the display for measuring LED light output during diagnostic/calibration operations.

When the diagnostic operation operates with an all white display, the three LED's at each pixel may be evaluated individually and collectively to assure that the pixel is contributing the proper spectrum and amount of white light. Through a diagnostic/calibration software package that interrelates output and peak wave length response for each red/green/blue LED at a pixel to the desired white light response, an iterative calibration may be undertaken at each pixel to correctly bias the drivers and thereby assure correct output.

It will be appreciated that split screen images may be displayed at the displays 30 . In the simplest application, a still image advertisement may be one half corporate logo and one half scenery. Beyond this simple application, split screen capability may be used to present a portion of the image as a corporate logo, or the like, and the remainder either real time (or near real time) video or still frame. For example, a previously qualified customer with acceptable internal content review procedures may have direct access to a display or displays for the purpose of displaying a real time (or near real time) sports event, news event, or the like, in conjunction with the customer's corporate logo. This display may be achieved by utilizing high speed servers 100 or by bypassing the servers altogether. High speed still image or video transfer may be facilitated by compression techniques such as JPEG and MPEG II, known in the art.

While advertising scheduling and purchasing may take place as described above where customers directly purchase time from available slots according to a fixed fee schedule, it will be appreciated that alternative modes may be used. For example, an auction system such as introduced by eBay Corporation may be used where all available slots are auctioned (a “total” auction). Additionally, a limited auction may be utilized where time may be purchased and booked for a set price, but all time not purchased at the set price becomes available through auction at a fixed time before the run time, for example, one month before run time. As another alternative for a portion of the available time slots, a high usage customer may establish a monthly advertising budget with the system operator that authorizes the operator to select the time slots for display of the customer's advertisements at “best available rate” pricing, taking advantage of last minute availability of time slots and other time slot placement techniques that enable the operator to more completely utilize the network. This or similar time slot placement practices when used for a portion of the available time slots may be implemented by a software package that takes into account the needs of both the customer and the system operator.

It will be appreciated that advertising content information may be transmitted to the electronic display locations by physically delivering an information storage device such as CD ROM, zip drive or DVD RAM to the location in those cases where the location may be remote, or for other reasons.

While the present invention has been described with reference to specific embodiments, it will be appreciated that modifications may be made without departing from the true spirit and scope of the invention.
