Abstract:
An electronic device feature display system for displaying information concerning the features inherent in a consumer electronics product having a limited number of alpha-numeric generating display segments thereon helps distinguish the product from its competitors while on the display shelf. One suitable use is for the fluorescent display panel of a video cassette recorder which may utilize a letter scrolling mode to form a continuous display of product features. Routines to make the feature banner practical on the sales floor are also discussed.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to means and/or method for displaying the features of a consumer electronics product. The present invention specifically relates to displaying the features of a consumer electronics product which has limited alpha-numeric display capability. 
     2. Discussion of the Related Art 
     On the display floor of a typical consumer electronics retailer there are usually many models of a particular type of product aligned together, such as televisions, VCRs, stereo, amplifiers, etc. In the case of televisions or computer monitors the consumer can make a direct comparison of picture quality or for stereo components comparison of audio quality is often possible. Often, however, direct comparison is impractical and/or expensive for the retailer and products are merely displayed more or less unattended. In this instance there maybe little to differentiate these products beyond the visual appearance of the outer casing of the product. 
     Especially in mass marketing or so called &#34;warehouse&#34; locations, product differentiation is left to &#34;feature banners&#34; which are labels applied to the products or their boxes to detail the inherent features of the products. Televisions or computer monitors having essentially unlimited text and pictorial display capability may be easily arranged to provide self-demonstration of their inherent features in an unattended sales environment. However, VCRs or other small electronic devices generally not hooked up to an output device may have little in the way of appearance differentiation, and are further constrained from self-demonstration by having a limited means for displaying information such as an alpha-numeric display of less than twelve segments. Thus, product differentiation means for the display models are doubly important yet very constricted by the capabilities of the consumer electronics device. 
     Thus, it would be desirable to provide a means for displaying the features of such a consumer electronics unit while on display on the sales floor in order to differentiate the product from the surrounding competitive units. 
     OBJECT OF THE INVENTION 
     It is, therefore, an object of the invention to provide an onboard electronic feature display contained within a consumer electronics product having a limited capability display device in order to serve as an unattended sales tool to differentiate the product from its competition.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     As seen in FIG. 1, a consumer electronics device having limited alpha-numeric display capability, such as a VCR 11 contains a fluorescent display panel 13 or FDP having an eleven segment alpha-numeric display 15 which would normally display text indicating the operational status of theVCR, e.g., fast forward, rewind, play, time and date, etc. For example, such an eleven segment display type number 11-BT-89GK or its equivalent isavailable from Futaba Corporation of Japan. The VCR further has switches 17constituting the operator interface for operator selection of the VCR functions. It will be appreciated that such switches may also be part of the VCR through its remote control unit (not shown). 
     As seen schematically in FIG. 2, within the VCR, or other consumer electronics device 11, is a microprocessor 19 which preferably, but not necessarily, has integrated therein a timer 21 and a static ROM memory 23.The microprocessor 19 of the preferred embodiment is available from Mitsubishi Electronics of Japan as chip number M38184MA. As can be seen, the microprocessor 19 is in electrical connection with switches 17 and thefluorescent display panel 13. The static ROM memory 23 contains the displaypanel control program and includes an operator interface recognition subroutine and a character generation sequence subroutine for affecting the feature display, as further explained below. 
     As seen in FIG. 3, an operational flow chart for the feature display means and the display panel control program, the electronics retailer will receive the VCR from the manufacturer at the start point, ref. no. 25. Thenext step is to remove the VCR from its shipping material as at ref. no. 27and apply AC power while placing the VCR on the display or retail floor. Once AC power is applied, the operator interface recognition subroutine isactivated. In order to enter the feature display mode the sales person willpress and hold a nonstandard or unusual switch combination, such as the fast forward and SP/EP buttons on the VCR for five seconds with the power selection switch off, as at ref. no. 29. As will be understood by the artisan, the microprocessor 19 with its timer function 21 controls the operator interface recognition subroutine and will be timing the length oftime that the switches 17 are depressed or closed. It will further be appreciated that other non-standard button combinations or switch closing times may be used. It is recommended that the feature display mode be entered into through a non-standard combination of switch selections so that the display mode will not be accidentally activated by the consumer/end user in his home. Further, by having the display mode featureactivated while the power selection switch is &#34;off&#34;, activation of the display mode by the end user is made further more unlikely. As seen at ref. no. 31, the VCR will then turn its power switch &#34;on&#34; and enter the feature display mode. 
     At this point the microprocessor will begin loading the character generation sequence subroutine from static ROM 23 in order to operate the eleven segment display 15 of the FDP 13 which, in the preferred mode is a continuous scrolling display of features such as &#34;ENGLISH/SPANISH LANGUAGE&#34;, &#34;1 YEAR/8 EVENT TIMER&#34;, &#34;4 VIDEO HEADS&#34;, &#34;STEREO MTS DECODING&#34;,etc. inherent in the VCR or other electronic device. Such a scrolling is illustrated in FIGS. 4-7 which illustrate a sequence of scrolling to display the &#34;1 YEAR/8 EVENT TIMER&#34; and &#34;4 VIDEO HEADS&#34; messages as shown in time sequence from FIGS. 4-7. Alternatively, as seen in FIGS. 8 and 9, the messages may be displayed sequentially rather than scrolled. 
     An interrupt subroutine is possible to take the VCR temporarily out of feature display mode as at ref. no. 33 by pressing any button on the remote control unit (RCU) or the face of the VCR. Once any switch is depressed, the VCR will operate as if it is in its normal mode, as at box ref. no. 35, in order to allow the consumer or sales person to demonstrate/investigate the features of the VCR. However, the display modeprogram for scrolling the features across the eleven segment display has only been interrupted. The timer 21 runs and is reset with each button push. After five minutes from the last switch selection the microprocessor19 will cancel the interrupt subroutine and start with the character generation sequence subroutine to again start scrolling the inherent features of the VCR across the FDP as at ref. no. 37. Thus, no sales personnel has to reactivate the unit into feature display mode by redoing the unique switch selection for a given time as shown at ref. no. 29. 
     If one wishes to exit the feature banner mode as at ref. no. 39, one must remove the AC power from the VCR as at ref. no. 41 by unplugging the VCR or removing power from the plug strip. Thus, a VCR sold from the display rack will have the feature display mode canceled and be ready to operate in normal mode for the end user. 
     While the present invention has been illustrated and described in connection with the preferred embodiments, it is not to be limited to the particular structure shown, because many variations thereof will be evident to one skilled in the art and are intended to be encompassed in the present invention as set forth in the following claims.
