In a specific embodiment, FIG. 8 is a cross-sectional view taken along D-D of FIG. 6, FIG. 9 is an enlarged view of area E of FIG. 8, and FIG. 10 is an enlarged view of area F of FIG. 8. As shown in fig. 8 to 10, the electrochromic layer 502 includes an electrochromic material layer 5022, an ion storage layer 5024 and an electrolyte layer 5026, the ion storage layer 5024 is used to provide ions to the electrochromic material layer 5022, and the electrolyte layer 5026 is disposed between the electrochromic material layer 5022 and the ion storage layer 5024 to serve as a module for the transport of ions between the electrochromic material layer 5022 and the ion storage layer 5024. It should be noted that the electrochromic layer 502 is well established in the art and will not be described herein.

The electrochromic device is further provided with a plurality of electrochromic isolating layers 702 (i.e., electrochromic isolating columns), the electrochromic isolating layers 702 are arranged with the first control module so as to separate two adjacent sub-receiving units on the first transverse control module 302, or the electrochromic isolating layers 702 are arranged perpendicularly with the second control module so as to separate two adjacent sub-transmitting units on the first longitudinal control module 402. The sub-cells between the two electrochromic barrier layers 702 are individually controlled by the control module, so that individual color change of the partial cells can be realized, and the partial cells can be distinguished from the adjacent non-color change. The electrochromic spacer 702 may be a photoresist or the like.

The electrochromic device also comprises a sealing structure, namely an edge sealing glue 802, which plays a role in sealing and prevents substances such as dust, water and the like from polluting the electrochromic device.

In the embodiment of the present application, whether the sub-units are lit up to realize color change is controlled by the control device 602 line by line, and the size of the sub-units is designed according to display requirements, for example, when a game is played on the back of a single-finger electronic device with a size of 4mm, only nine sub-units of the first horizontal control module 302 and the first vertical control module 402 are needed.

Fig. 2 to fig. 10 illustrate the sub-receiving module as six rows and three columns and the sub-transmitting module as six rows and three columns, and n rows and m columns may be designed according to requirements. As shown in fig. 11, a plurality of rows and a plurality of columns are designed as required, the size of the sub-unit is reduced to form a pixel point, the entire pattern is displayed by lighting control of each point, 1102 is a pattern for lighting a local sub-unit, and 1104 is a final display pattern. The color change of each subunit is controlled by the voltage of the row and column to display a required pattern, specifically, RX1 to RX (n), TX1 to TX (m) are controlled to be electrified in a time-sharing mode row by row, the color change can be completed within milliseconds by the color change technology, and the formation of one pattern can be rapidly realized. For example, the display of the clock is realized, a pattern different from an uncolored color is displayed by controlling local electrochromism, a mutual capacitance touch function is realized, when touch is required, the sub-sending module outputs a signal, and the sub-receiving module receives the signal and processes the signal through the control device to detect the touch position. It should be noted that the sub-receiving module may be designed on the upper layer or the lower layer, and the sub-transmitting module is designed on the other of the upper layer or the lower layer.

In the embodiment of the application, on one hand, small control units are divided for the control modules on the upper and lower substrates, and local color changing and touch control functions are realized by controlling each small control unit. On the other hand, by adding the isolation layer, the independent color change control of the small control unit is realized, and the display effect is improved. On the other hand, an independent control device is designed, and the display touch and the whole electrochromic device are controlled by time-sharing multiplexing.
