In order to enrich the appearance effect of the shell, some shells realize the color change effect by using electrochromic materials or photochromic materials, and the like, and although the materials can change the color and the like of the shell, the materials have the problems of slow response time, insensitive reaction, unstable color change effect and the like. For example, the response time of the currently common electrochromic material is generally in the second level, and the response time is long, so that the color change of the shell is slow, the color change sensitivity is poor, and the user experience is poor; in addition, the response time of the current photochromic material is also slow, and the color, the color changing effect and the like of the photochromic material are easily influenced by the ambient light due to the uncontrollable illumination condition, for example, the color changing effect of the shell is uncontrollable and the color changing is not uniform after the ambient light is shielded, and the appearance effect is not ideal.

Detailed Description

Examples of the present application are described in detail below and are illustrated in the accompanying drawings. The examples described below with reference to the drawings are illustrative and intended to be used for explaining the present application and are not to be construed as limiting the present application.

In one aspect of the present application, a housing is presented. According to some examples of the present application, referring to fig. 1 and 2 (fig. 2 is a schematic cross-sectional structure along the direction AA' in fig. 1), the housing 1000 includes: the liquid crystal color changing device comprises a housing base 100 and a dye liquid crystal color changing device 200, wherein the dye liquid crystal color changing device 200 is arranged on at least a part of the surface of the housing base 100, the dye liquid crystal color changing device 200 comprises a first transparent conductive layer 210, a second transparent conductive layer 220, a frame sealing adhesive 230 and a dye liquid crystal layer 250, wherein the first transparent conductive layer 210 and the second transparent conductive layer 220 are oppositely arranged, the frame sealing adhesive 230 is arranged between the first transparent conductive layer 210 and the second transparent conductive layer 220 and defines an accommodating space 240 between the first transparent conductive layer 210 and the second transparent conductive layer 220, the dye liquid crystal layer 250 is arranged in the accommodating space 240, the color of the dye liquid crystal layer 250 can change along with the change of the voltage between the first transparent conductive layer 210 and the second transparent conductive layer 220, wherein the dye liquid crystal color changing device 200 is provided with a first terminal (not shown in the figure) electrically connected with the first transparent conductive layer 210 on the side of the frame sealing adhesive 230 away from the accommodating space, and a second terminal (not shown) electrically connected to the second transparent conductive layer 220, the first terminal and the second terminal being located on the same side of the dye liquid crystal layer 250. From this, this dyestuff liquid crystal color changing device 200's line of walking is comparatively simple, and this casing 1000 has abundant colour effect and the effect of discolouing, and the response speed that just discolours is fast, and colour effect is stable, and the product expressive force is strong.

For convenience of understanding, the following is a brief description of the principle by which the housing 1000 can obtain the above-mentioned advantageous effects:

as described above, in the conventional electronic device, the color, the pattern, and the like of the housing are relatively fixed and single, so that the effect of changing a plurality of colors cannot be realized, and the appearance expressive force is not ideal. Although the shell prepared by using the electrochromic material or the photochromic material and the like can realize the color change effect, the materials all have the problems of slow response time, insensitive reaction, unstable color change effect and the like. And the casing in this application through set up dyestuff liquid crystal color change device on at least some surfaces at the casing base member, can realize abundant discoloration effect and color effect, and the response speed that just discolours is fast, and the color effect is stable. It should be noted that, when dye liquid crystal is prepared by adding a dye (e.g., dichroic dye) to a liquid crystal, the liquid crystal exhibits a color, and the dye liquid crystal may have different colors depending on the added dye. After the dye is added into the liquid crystal, the dye molecules can keep the oriented parallel arrangement with the liquid crystal molecules, the dye molecules and the liquid crystal molecules generate the rotation with the same phase under the action of an electric field, the arrangement orientation of the dye molecules after the rotation is different, and the absorption to light is different, so that the color change can be realized. Thus, by adding different dyes, the dye liquid crystal can have different colors, such as gray black, blue, orange, etc., and under the control of voltage, the change between the colors of gray black to transparent, blue to transparent, orange to transparent, etc., can be realized. Therefore, the dye liquid crystal color changing device can realize very rich colors and very rich color changes, so that the shell has a cool appearance effect, and the appearance expressive force of a product can be improved; in addition, by controlling the voltage applied between the first transparent conductive layer and the second transparent conductive layer, the color of the dye liquid crystal changes very quickly (corresponding to the response time of the liquid crystal device, the response time can be in millisecond level), namely, the color can be changed quickly, the color change sensitivity is high, and the user experience is further improved; in addition, the dye liquid crystal layer has stable color, is not influenced by external environment (such as light rays and the like), and has good use performance.

And, in the dyestuff liquid crystal colour change device of this application, the first terminal of being connected with first transparent conducting layer electricity to and the second terminal of being connected with the transparent conducting layer electricity of second set up the homonymy at the dyestuff liquid crystal layer, consequently, this dyestuff liquid crystal colour change device's line of walking is comparatively simple, and is convenient for connect this first terminal, second terminal and flexible circuit board, and with its and electronic equipment inside mainboard etc. connect, the outward appearance effect and the performance of this casing have further been improved.

According to some examples of the present application, the dye-liquid crystal color-changing device 200 may be disposed on at least a portion of the surface of the housing substrate 100, that is, the dye-liquid crystal color-changing device 200 may be disposed on a portion of the surface or the entire surface of the housing substrate 100, and one skilled in the art can design the device as desired. It should be noted that the dye-liquid crystal color changing device 200 may be disposed on an inner side of the housing base 100 (the "inner side" is a side facing the inside of the electronic device when the housing 1000 is used in the electronic device), so that the housing base 100 may protect the dye-liquid crystal color changing device 200 from being scratched, and the like, and is beneficial for connecting a main board and the like inside the electronic device with the dye-liquid crystal color changing device 200 to control the dye-liquid crystal color changing device 200 to change color.

Specifically, the housing base 100 may be a transparent substrate, for example, a transparent glass substrate, and the housing base 100 may also have appearance effects such as certain color and texture. It should be noted that, when the dye-liquid crystal color-changing device 200 is disposed on a part of the surface of the housing base 100, the region of the housing base 100 corresponding to the dye-liquid crystal color-changing device 200 may be transparent, thereby facilitating the color and the color change effect of the dye-liquid crystal color-changing device 200 to be visually observed; and the area of the housing base 100 not provided with the dye-liquid crystal color changing device 200 can have appearance effects such as color, texture, pattern, etc., therefore, the color and the color changing effect of the dye-liquid crystal color changing device 200 can be combined with the color and the pattern of the housing base 100, the appearance effect of the housing 1000 is further enriched, and the appearance expressive force of the product is improved. Specifically, the shape and size of the dye-liquid crystal color changing device 200 are not particularly limited, and may be, for example, a square shape, a circular shape, a pattern, a number, a letter, or the like, thereby further enhancing the appearance of the housing 1000.

Therefore, the first terminal and the second terminal can be easily integrated on the first transparent conductive layer 210 or the second transparent conductive layer 220, further simplifying the routing.

According to some examples of the present application, referring to fig. 2, 4 and 5 (fig. 5 is an enlarged view of a circled portion in fig. 4), when the dye-liquid crystal color changing device 200 is disposed on the surface of the housing base 100, the first transparent conductive layer 210 may be disposed near the housing base 100, and the first terminal and the second terminal (not shown) may be formed by the first transparent conductive layer 210 disposed on a side of the sealant 230 away from the accommodating space 240. Specifically, the first transparent conductive layer 210 may include: the electrode region 10 is located inside the accommodating space 240, and the binding region 20 is located outside the accommodating space 240 (the binding region 20 may include a region corresponding to the frame sealing adhesive 230 and a region of the frame sealing adhesive 230 far away from the accommodating space 240). Specifically, the binding region 20 may further include a first binding region 21 and a second binding region 22, where the first binding region 21 is connected to the electrode region 10, the second binding region 22 is connected to the electrode region 10, and the second binding region 22 and the first binding region 21 are both provided with a separation line (i.e., the second binding region 22 is separated from the electrode region 10, and the second binding region 22 is separated from the first binding region 21), and the second binding region 22 is electrically connected to the second transparent conductive layer 220. That is, the first transparent electrode layer 210 located in the accommodating space 240 can be used as an electrode for cooperating with the second transparent conductive layer 220 to control the dye molecules and the liquid crystal molecules in the accommodating space 240 to deflect, etc.; the portion of the first transparent electrode layer 210 except the electrode region 10 may be used as a binding region 20 for connecting and binding the first transparent electrode layer 210 and the second transparent electrode layer 220 with an external circuit, respectively. Specifically, the first bonding region 21 may constitute a first terminal electrically connected to the first transparent conductive layer 210, and the second transparent conductive layer may constitute a second terminal electrically connected to the second transparent conductive layer. Therefore, the voltage between the first transparent conductive layer 210 and the second transparent conductive layer 220 can be simply and conveniently controlled, the dye liquid crystal layer 250 is controlled to change color, the dye liquid crystal color changing device 200 is simple in structure, simple in wiring, convenient to attach to the shell substrate 100, and convenient to connect to a mainboard and the like inside the electronic equipment.

Specifically, the frame sealing adhesive 230 in the second binding region 22 in the front projection may have a conductive material, and the second transparent conductive layer 220 may be electrically connected to the second binding region 22 through the conductive material. Therefore, the second binding region 22 and the second transparent conductive layer 220 can be electrically connected simply and conveniently by the conductive material arranged on the frame sealing adhesive 230 without complex wiring, the structure of the dye liquid crystal color changing device 200 is simple, and the appearance of the housing 1000 is further improved. Specifically, the specific type and arrangement manner of the conductive material are not particularly limited as long as the second bonding region 22 and the second transparent conductive layer 220 can be electrically connected, for example, the conductive material may include conductive particles 210 (shown in fig. 6) filled in the frame sealing adhesive 230 whose front projection is located in the second bonding region 22, or the conductive material may include conductive paste or the like coated on the outer side of the frame sealing adhesive 230 whose front projection is located in the second bonding region 22. Specifically, the type of the conductive particles 231 is not particularly limited, and for example, the conductive particles 231 may be conductive gold balls or the like. Specifically, the type of the conductive paste is not particularly limited, and may be, for example, a conductive silver paste or the like.

It should be noted that, referring to fig. 3, when the first terminal and the second terminal (not labeled in the figure) are formed by the second transparent conductive layer 220 disposed on the side of the frame sealing adhesive 230 away from the accommodating space 240, the structure of the second transparent conductive layer 220 may be the same as the structure of the first transparent conductive layer 210 having the first terminal and the second terminal, that is, the second transparent conductive layer 220 may include an electrode region and a binding region, and details thereof are not repeated herein.

According to some examples of the present application, the material forming the first transparent conductive layer 210 and the second transparent conductive layer 220 is not particularly limited as long as it has good conductivity and high transparency, and for example, the material forming the first transparent conductive layer 210 and the second transparent conductive layer 220 may include at least one of Indium Tin Oxide (ITO), fluorine-doped tin oxide (FTO), and aluminum-doped zinc oxide (AZO), which have good conductivity and high transparency. Specifically, the sheet resistance of the first transparent conductive layer 210 and the second transparent conductive layer 220 may be less than 50 Ω. For example, the conductivity may be less than 40 Ω, less than 30 Ω, less than 20 Ω, and the like, so that the first transparent conductive layer 210 and the second transparent conductive layer 220 have good conductivity; the first transparent conductive layer 210 and the second transparent conductive layer 220 have high transparency, and can better show the color generated by the dye liquid crystal layer 250.

According to some examples of the present application, the specific type of the dye liquid crystal forming the dye liquid crystal layer 250 is not particularly limited, for example, dichroic dye molecules, the color of which is not particularly limited and which can be selected by one skilled in the art as needed, may be added to the liquid crystal to form a liquid crystal dye. Specifically, the thickness of the dye liquid crystal layer 250 may be 1 to 50 μm, for example, 4 μm, 10 μm, 15 μm, 20 μm, 25 μm, 30 μm, 35 μm, 40 μm, or the like. The color change time is prolonged, and the electrochromic effect is influenced. Therefore, when the thickness of the dye liquid crystal layer 250 is within the above range, a good color effect and a good color change effect can be exhibited, and the performance of the dye liquid crystal color change device 200 is further improved.

Thus, the first alignment layer 260 and the second alignment layer 270 may facilitate the deflection of the liquid crystal molecules in the accommodating space 240, etc., further improving the performance of the dye-liquid crystal color changing device 200.

May be 80nm, may be 50nm, etc., and thus, when the thicknesses of the first alignment layer 260 and the second alignment layer 270 are within the above ranges, the liquid crystal molecules in the dye liquid crystal layer 250 may be more favorably accelerated to be deflected.

According to some examples of the present application, referring to fig. 8, the dye-liquid crystal color changing device 200 may further include: a first substrate 280 and a second substrate 290, wherein the first substrate 280 is disposed on a side of the first transparent conductive layer 210 away from the dye liquid crystal layer 250, and the second substrate 290 is disposed on a side of the second transparent conductive layer 220 away from the dye liquid crystal layer 250. Specifically, the material forming the first substrate 280 and the second substrate 290 may include glass, so that the transparency of the first substrate 280 and the second substrate 290 is better, and the color of the dye liquid crystal layer 250 can better penetrate through the first transparent conductive layer 210 and the first substrate 280.
