the ink layer comprises a plurality of trapezoidal micro-cups which are arranged side by side, first ink particles and second ink particles are arranged in the trapezoidal micro-cups, and the electrical property of the first ink particles is opposite to that of the second ink particles.

Preferably, the first ink particles are red ink particles, and the second ink particles are black ink particles or white ink particles.

Preferably, the base and the menu body are integrally formed, and the base and the menu body are in an inverted T shape.

Preferably, the intersection of the base and the menu body is provided in an arc shape.

Compared with the prior art, the utility model provides an electronic menu with ink screen has following beneficial effect:

through setting up first transparent electrode layer, second transparent electrode layer for this ink screen both sides can show, only the ground colour and the typeface colour of demonstration are inconsistent, but the actual content that shows on two sides is the same on the whole. Therefore, the electronic menu displays information such as various dishes and prices when a eater orders dishes, and the information such as the dishes and the prices can be replaced at any time; when the eater is absent, advertisements such as photos of various dishes can be displayed.

Detailed Description

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "including" and "having," and any variations thereof, in the description and claims of this application and the description of the above figures are intended to cover non-exclusive inclusions. The terms "first," "second," and the like in the description and claims of this application or in the above-described drawings are used for distinguishing between different objects and not for describing a particular order.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

An embodiment of the utility model provides an electronic menu with ink screen, as shown in fig. 1 and fig. 2, it includes: the menu comprises a base 100, a menu body 200 arranged on the base 100, an ink screen 300 arranged on the menu body 200, and a driving circuit board (not shown) for driving the ink screen 300 arranged in the base 100; the ink screen 300 comprises a first transparent electrode layer 301, a second transparent electrode layer 302, and an ink layer 303 arranged between the first transparent electrode layer 301 and the second transparent electrode layer 302, wherein a first transparent substrate 304 is arranged on the surface of the first transparent electrode layer 301, and a second transparent substrate 305 is arranged on the surface of the second transparent electrode layer 302; the ink layer 303 includes a plurality of trapezoidal microcups 313 arranged side by side, the trapezoidal microcups 313 are provided therein with first ink particles 323 and second ink particles 333, the first ink particles 323 and the second ink particles 333 are electrically connected, and the ink screen 300 is embedded on the menu body 200.

As shown in fig. 2, the display principle of the ink screen 300 is as follows: different voltages are applied to the first transparent electrode layer 301 and the second transparent electrode layer 302 by the driving circuit board, and by utilizing the principle that the positive and negative electrodes attract each other, the charged ink particles 323 in the ink layer 303 move to the electrode layer with different charges, for example, the positively charged ink particles move to the transparent electrode layer with the negative charge, and the negatively charged ink particles move like the transparent electrode layer with the positive charge, so that the positively charged ink particles and the negatively charged ink particles move to two ends of the ink layer 303, and thus, two colors can be displayed. And after the first transparent electrode layer 301 and the second transparent electrode layer 302 are only required to be electrified for display, the display is not influenced after the power is cut off. Because the ink screen 300 does not need to use a battery after displaying, the power supply problem does not need to be worried about, and the use is very convenient.

In addition, due to the first transparent electrode layer 301 and the second transparent electrode layer 302, both sides of the ink screen 400 can be displayed, only the displayed ground color and the displayed font color are not the same, but the actual contents displayed on both sides are the same as a whole. Therefore, the electronic menu displays information such as various dishes and prices when the eater orders dishes, enables the dishes and prices to be changed at any time, and displays advertisements such as photographs of various dishes when the eater is not available.

In a further preferred embodiment of the present invention, the first ink particles 323 are red ink particles, and the second ink particles 333 are black ink particles or white ink particles.

In a further preferred embodiment of the present invention, the base 100 and the menu body 200 are integrally formed, and the base 100 and the menu body 200 are inverted T-shaped.

In a further preferred embodiment of the present invention, the intersection of the base 100 and the menu body 200 is formed in an arc shape.

To sum up, the utility model discloses an electronic menu with ink screen through setting up first transparent electrode layer, second transparent electrode layer for this ink screen both sides can all show, and only the ground colour that shows and typeface colour are inconsistent, but the actual content that two sides were shown on the whole is the same. Therefore, the electronic menu displays information such as various dishes and prices when a eater orders dishes, and the information such as the dishes and the prices can be replaced at any time; when the eater is absent, advertisements such as photos of various dishes can be displayed.

It is to be understood that the above-described embodiments are merely illustrative of some, but not restrictive, of the broad invention, and that the appended drawings illustrate preferred embodiments of the invention and do not limit the scope of the invention. This application is capable of embodiments in many different forms and is provided for the purpose of enabling a thorough understanding of the disclosure of the application. Although the present application has been described in detail with reference to the foregoing embodiments, it will be apparent to one skilled in the art that the present application may be practiced without modification or with equivalents of some of the features described in the foregoing embodiments. All equivalent structures made by using the contents of the specification and the drawings of the present application are directly or indirectly applied to other related technical fields and are within the protection scope of the present application.
