Abstract

An image display device is provided that is convenient to carry as a card for the purpose of image display. One side of a cash card type plate A is used as an electronic image display display 1 and contains electronic components based on a wiring circuit sufficient to display an electronic image inside the plate A and is used for power supply. The battery 2 and the content-containing storage medium 3 are accommodated or can be accommodated to obtain a card-type image display. Also, ON-OFF and image selection switches are provided on the outer surface based on appropriate wiring. [Selection] Figure 1

Description

The present invention relates to a plate-like image display tool similar to a cash card.

Recently, the mainstream of electronic images has been shifted from the former cathode ray tube to liquid crystal and plasma displays, and organic EL has also reached the practical use range, and significant progress has been made in reducing power consumption and improving image quality. Therefore, televisions and the like are becoming thinner and larger, and on the other hand, image refinement is also progressing on monitors such as mobile phones. In addition, ICs and storage media that enable this have been remarkably miniaturized or increased in capacity.

Under such circumstances, small monitors are already used in cellular phones, game machines, PDAs, portable TVs, ultra-small personal computers, etc., but these monies (displays) are all provided as secondary necessary devices. The main body of the device having a main purpose function is required to have a much larger volume and a higher price than a monitor unit even for a mobile phone.

An object of the present invention is to provide an image display tool that is most portable and convenient for the purpose of image display in accordance with the current situation.

One side of the cash card type plate A is used as an electronic image display 1, and an electronic component (not shown) based on a wiring circuit sufficient to display an electronic image inside the plate A is accommodated, and a power source The card-type image display device of the present invention is formed by accommodating the battery 2 and the content-containing storage medium 3 for use.

Here, the “cash card type plate-like body” is the same as or similar to the standard size of a cash card or a telephone card whose vertical and horizontal dimensions are well known, and the thickness is a level suitable for expressing as a plate type. It means that for the time being it will be a little thicker than an actual cash card. Of course, the surface is not always flat like a card, and there may be a slight level difference or a groove.

The electronic image display 1 may be a liquid crystal, but is preferably a reflective type that does not require a backlight or an organic EL. A technique for accommodating an electronic circuit for displaying this image at a level of at least several hundred thousand pixels in a card-like plate has already been achieved.

As the simplest form, there is a type in which an image is only displayed when the battery 2 and the storage medium 3 are connected in a circuit. That is, as long as there is a battery output, when the storage medium 3 with content such as a micro SD card is inserted, an image is displayed on the display 1 immediately.

Since the battery 2 must be of a size that can be accommodated in a card-like plate body, for example, a thin lithium-ion battery or the like is applicable. For this, a polyether that is said to be put into practical use within 2 to 3 years is used as an electrolyte. The sheet-like all solid state secondary battery used is particularly preferable. In addition, for example, the image may be displayed as long as light is applied to the installed solar cell.

Further, as a more convenient form, there may be mentioned one in which ON-OFF and image selection switches are provided on the outer surface based on appropriate wiring. This is preferably a touch type that is already employed in a card type calculator or the like.

In addition, if necessary, it is optional to provide a connection terminal for an external device or the like on a side portion or the like based on appropriate wiring.

According to the present invention, there is an effect that a content image obtained by photographing or downloading by himself can be visualized extremely easily and at low cost together with the minimum visibility and the convenience of carrying the same as a cash card.

In the overall shape, the vertical and horizontal dimensions are the size of a cash card, and the thickness is about 3 mm. The display uses an organic EL so as to occupy about 90% of the space on the front side, and the touch-type ON-OFF switch 4 and the image selection switch 5 are wired and connected to the remaining space in the same way as existing ones. A memory card slot 6 such as a micro card, a charging terminal 7 and an external connection terminal 8 are provided on the side, and an all solid-state sheet-like lithium ion secondary battery (not shown) is accommodated therein. Needless to say, the present invention is not limited to this example.

The production of the present invention described above is sufficiently possible with existing technology, and the most desirable battery will be put into practical use in the near future. Therefore, it can be said that the industrial applicability of the present invention with high needs is sufficient.
