Detailed Description

Features and exemplary embodiments of various aspects of the present application are described in detail below to make the objects, technical solutions and advantages of the present application more apparent, and to further describe the present application in conjunction with the accompanying drawings and the detailed embodiments. It should be understood that the specific embodiments described herein are intended to be illustrative of the application and are not intended to be limiting. It will be apparent to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by showing examples of the present application.

As shown in fig. 1 and 2, in one embodiment of the present application, there is provided a display substrate assembly 1 including,

a transparent substrate 11;

an electrochromic layer disposed on the transparent substrate 11, the electrochromic layer being formed by coating;

the PCB board 12 is provided with a plurality of printed circuit boards,

a plurality of display modules 13 are etched on the PCB 12, and the display modules 13 can be independently controlled;

the imaging module 13 is covered with ion storage material;

electrolyte is injected between the transparent substrate 11 and the PCB 12, and then the transparent substrate 11 and the PCB 12 are bonded and packaged, and the electrochromic layer is positioned between the transparent substrate 11 and the PCB 12;

and a connector 14 electrically connected to the PCB 12 for controlling the potential of the display module 13 in the PCB 12.

In this application, the technical scheme of two-layer transparent base plate + ITO conducting layer is changed into the scheme of one-layer transparent base plate + one-layer PCB board, and the ITO conducting layer also is consequently replaced by the copper wiring in the PCB, because the PCB board has excellent welding performance, connector 14 can directly weld with PCB board 12, as shown in FIG. 2, then connector 14 links to each other with display module 13 through the inside wiring of PCB board 12 for control display module 13's electric potential.

When a potential difference between the transparent substrate 11 and the PCB board 12 is formed, the ion storage material covered on the display module 13 will be ion-deintercalated, so that ions and electrons will be embedded in the electrochromic layer, and thus color change is performed in the same segment area of the display module 13, thereby completing display.

In another embodiment of the present application, the transparent substrate 11 is made of one or more materials selected from a transparent glass substrate, a polydimethylsiloxane substrate, a polyurethane substrate, and a polybutylene terephthalate substrate. The selected materials are all chemically inert materials, so that the reaction with electrolyte is difficult to occur, and the whole system is stable.

In one embodiment of the present application, as shown in fig. 1, the developing module 13 includes 7 pad patterns, which are segments of the arabic numeral 8. In this embodiment, the Arabic numerals 8 are modularized, because of the particularity of the numerals 8, the numerals 8 are composed of 7 small segments (strokes) in total, each of which is individually controlled, and any one of numerals 0 to 9 can be displayed. By adjusting the voltages of the 7 pad patterns, the individual segments are controlled to be displayed, and digital display of 0 to 9 can be realized by electric driving.

By adjusting the voltage of the developing module 13, the deintercalation state of ions stored in the ion storage material covered on the corresponding developing module 13 can be controlled, so that the ions are deintercalated into the electrochromic layer, and the corresponding pattern of the developing module 13 is displayed.

In one embodiment of the present application, the visualization module 13 is coated with an electrically inert metal.

The present application takes advantage of the excellent conductive properties inside the PCB and charges the electrochromic material of the corresponding area by outputting a voltage at the developing module 13 to complete the display. However, the inside of the PCB is made of copper, copper is exposed after the PCB is windowed, and copper reacts with the electrolyte under the power, so that the development module 13 is gold-plated for conductivity and not to corrode the device. The electrically inert metal is a metal which does not react chemically with the electrolyte.

Further, the electrically inert metal is gold, which is relatively versatile because of its stable chemical properties.

In another embodiment of the present application, the PCB board 12 is coated with solder resist ink outside the area of the visualization module 13. The ink can realize better color contrast, and different electrochromic materials select the ink with proper colors, and the colors of the ink depend on the contrast of the electrochromic materials.

As a preferred scheme, the transparent substrate 11 and the PCB 12 are encapsulated by sealant.

In another embodiment of the present application, the ion storage material is an ion-freely-deintercalatable layered material. Preferably, the ion storage material is a lithium ion battery positive electrode material, including one or more of lithium cobaltate and ternary positive electrode materials. The materials are easy to obtain and have good technical effects.

the FPC strip is connected to a connector 14,

the control terminal 4 is operable to control the output potential of the power supply 3, and the battery output from the power supply 3 is output to the connector 14 via the FPC strip.

In the actual operation process of the application, the FPC strip directly connects the display substrate assembly 1 with the power supply 3, the potential output of the power supply 3 is directly controlled through the intelligent control interface of the control end 4, and potential difference is formed on the display module of the substrate assembly, so that the color development process is completed.
