the ink layer is internally provided with first ink particles and second ink particles, and the first ink particles and the second ink particles have opposite electrical properties;

the back plate is provided with a driving controller.

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

Preferably, the outer surface of the housing is arranged in a rectangular shape.

Preferably, the housing is provided with a mounting hole at each of four corners thereof.

Compared with the prior art, the utility model provides a house plate with ink screen has following beneficial effect:

after the first electrode layer and the second electrode layer are electrified and displayed, the display is not influenced after the first electrode layer and the second electrode layer are powered off, the power supply problem does not need to be worried about, the display can be continuously used after the power is off, and the use is very convenient.

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 a house plate with ink screen, as shown in fig. 1 and fig. 2, it includes: the ink screen 200 comprises a shell 100, wherein an ink screen 200 is arranged in the shell 100, the ink screen 200 comprises a first electrode layer 201, a second electrode layer 202 and an ink layer 203 arranged between the first electrode layer 201 and the second electrode layer 202, a transparent substrate 204 is arranged on the surface of the first electrode layer 201, and a back plate 205 is arranged on the surface of the second electrode layer 202; the ink layer 203 is provided with first ink particles 213 and second ink particles 223, and the first ink particles 213 and the second ink particles 223 have opposite electrical properties; the back plate 205 is provided with a driving controller 206.

As shown in fig. 2, the display principle of the ink screen 200 is: different voltages are applied to the first electrode layer 201 and the second electrode layer 202 by the driving controller 206, and the principle of positive and negative attraction is utilized, so that the charged ink particles in the ink layer 203 move to the electrode layer with different charges, for example, the positively charged ink particles move to the negatively charged transparent electrode layer, and the negatively charged ink particles move like the positively charged transparent electrode layer, so that the positively charged ink particles and the negatively charged ink particles move to two ends of the ink layer 203, and thus two colors can be displayed. In addition, after the first electrode layer 201 and the second electrode layer 202 are only needed to be powered on for display, the display is not affected after the power is cut off. Because the ink screen 200 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.
