[0038] Combine the following Figures 1 to 18 The color changing module 100, housing, electronic device, privacy film and vehicle according to the embodiments of the present application are described.

[0039] like Figure 1 and Figure 2 As shown, the color-changing module 100 according to some embodiments of the present application includes a first color-changing layer 102, a first electrode 104 and a second electrode 106; the first color-changing layer 102 includes at least two electrochromic materials 126, and the at least two electrochromic materials 126 have different colors under different voltages; the first electrode 104 is located on a first side of the first color-changing layer 102; the second electrode 106 is located on a second side of the first color-changing layer 102, and the first side and the second side are two opposite sides of the first color-changing layer 102; wherein the first electrode 104 and the second electrode 106 can apply voltage to the first color-changing layer 102.

[0040] The color-changing module 100 according to the embodiment of the present application includes a first color-changing layer 102, and the first color-changing layer 102 includes at least two electrogenic materials 126, and the at least two electrogenic materials 126 can change color under different voltage driving. The color-changing module 100 also includes a first electrode 104 and a second electrode 106, the first electrode 104 is located on the first side of the first color-changing layer 102 in the thickness direction, and the second electrode 106 is located on the second side of the first color-changing layer 102 in the thickness direction. A voltage can be applied to the first color-changing layer 102 through the first electrode 104 and the second electrode 106 to change the color of the first color-changing layer 102.

[0041] Since the color of the color changing module 100 can change during use, the color of the color changing module 100 is prevented from being too single, and the color of the color changing module 100 is made richer.

[0042] Since the first color-changing layer 102 includes at least two electrochromic materials 126, the at least two electrochromic materials 126 can change color when driven by different voltages. Then, applying different voltages to the first color-changing layer 102 through the first electrode 104 and the second electrode 106 can further enrich the color of the first color-changing layer 102 and further enhance the color diversity of the color-changing module 100.

[0043] When the color-changing film set is attached to the back cover of an electronic device, or the color-changing module 100 is used as the back cover of the electronic device, the functionality, interest and aesthetics of the back cover can be improved.

[0044] Specifically, the first electrode 104 and the second electrode 106 are indium tin oxide (ITO) electrodes.

[0045] Specifically, the first color-changing layer 102 is an electrochromic (EC) layer.

[0046] According to some embodiments of the present application, Figure 1 and Figure 2 As shown, at least two electroluminescent materials 126 are electroluminescent materials, and the color-changing module 100 also includes an electron transport layer 108, a thin cathode 110 and a hole transport layer 112; the electron transport layer 108 is attached to the first side of the first color-changing layer 102; the thin cathode 110 is attached to the electron transport layer 108, and the first electrode 104 is attached to the thin cathode 110; the hole transport layer 112 is attached to the second side of the first color-changing layer 102, and the second electrode 106 is attached to the hole transport layer 112.

[0047] In this embodiment, driven by the voltage applied by the first electrode 104 and the second electrode 106, the electrons injected by the cathode and the holes injected by the anode are recombined in the light-emitting layer to form electron-hole pairs at a bound energy level, namely, excitons. The excitons radiate excitation photons, thereby causing the light-emitting layer to generate visible light.

[0048] Since at least two electroluminescent materials 126 are included, both of which are electroluminescent materials and can emit light of different colors under different voltages, the color of the color-changing module 100 can be changed while the color of the color-changing module 100 is made richer.

[0049] According to some embodiments of the present application, Figure 1 As shown, the color-changing module 100 further includes a first base color layer 114 , and the first base color layer 114 is attached to the second electrode 106 .

[0050] In this embodiment, the color-changing module 100 further includes a first base color layer 114, and the first base color layer 114 has a color different from the color produced by the at least two electrogenic materials 126. When the at least two electrogenic materials 126 are not excited, the color of the color-changing module 100 is the color of the first base color layer 114, further enriching the color types of the color-changing components.

[0051] Specifically, the first base color layer 114 is a blue film, and at least two electroluminescent materials 126 can be red and green mixed luminescent materials. The red and green mixed luminescent materials are introduced into the luminescent layer. Different luminescent materials are excited by different voltages. The luminescent color of the color-changing module 100 will gradually change from pure red to yellow and then to pure green as the driving voltage increases. Of course, this regulation method is not progressive, but presents a specific color at a specific voltage.

[0052] Specifically, the first base color layer 114 is attached to the second electrode 106 via a first optically clear adhesive 122 (OCA).

[0053] Specifically, the first base color layer 114 is a printing ink layer.

[0054] like Figure 3 and Figure 4 As shown, when the color-changing module 100 is not energized or energized with V1 = 0V, the color-changing module 100 does not emit light and appears transparent, so that the entire rear cover plate displays the color of the first base color layer 114 .

[0055] like Figure 3 and Figure 5 As shown, when a smaller voltage V2 is applied to the first electrode 104 and the second electrode 106, the green light-emitting material in the electroluminescent material cannot be excited, but the red light-emitting material is excited, and the entire color-changing module 100 emits red light. Since the light-emitting device is located on the first base color layer 114, the red color covers the blue color, and the entire back cover appears red.

[0056] like Figure 3 and Figure 6 As shown, when the color-changing module 100 is powered by a moderate voltage V3, part of the red light-emitting material and part of the green light-emitting material in the color-changing module 100 are excited to emit light, and the red light and the green light are mixed to present a yellow effect. Moreover, since the light-emitting device is located on the first base color layer 114, the yellow covers the blue, and the entire back cover shows a yellow color that is a combination of red and green.

[0057] like Figure 3 and Figure 7As shown, when the color-changing module 100 is energized with a relatively large voltage V4, the green light material in the color-changing module 100 is excited to emit strong light, the light intensity of the red material decreases, and the entire color-changing module 100 displays green. Since the light-emitting device is located on the first base color layer 114, the green covers the blue, and the entire back cover displays green.

[0058] like Figure 8 As shown, the ordinate is the normalized EL Intensity (Normalized EL Intensity), the unit is arbitrary unit (Arbitrary Unit, AU), and the abscissa is the wavelength of the absorption spectrum (400nm to 750nm), the unit is nanometer.

[0059] As the voltage applied by the first electrode 104 and the second electrode 106 to the first color-changing layer 102 changes, the colors of the color-changing module 100 are transparent, red, yellow, and green in sequence.

[0060] The luminous color of the first color-changing layer 102 will gradually change from pure red (driving voltage is -2V) to orange (driving voltage is -2.5V), yellow (driving voltage is -3.2V), yellow-green (driving voltage is -4V) and then to pure green (driving voltage is -5V) as the driving voltage increases.

[0061] According to some embodiments of the present application, Figure 2 As shown, the color-changing module 100 further includes a first substrate 116 and a second base color layer 118 ; a first side of the first substrate 116 is attached to the second electrode 106 ; and the second base color layer 118 is attached to a second side of the first substrate 116 .

[0062] In this embodiment, the color-changing module 100 includes a first substrate 116. When preparing the color-changing module 100, the first color-changing layer 102, the first electrode 104, the second electrode 106, the electron transport layer 108, the thin cathode 110 and the hole transport layer 112 can be first prepared on the first substrate 116, and then the second base color layer 118 is laminated on the first substrate 116, thereby reducing the material requirements for each part of the color-changing module 100 and thereby reducing the cost of the color-changing module 100.

[0063] According to some embodiments of the present application, Figure 1 and Figure 2 As shown, the color-changing module 100 further includes a first cover plate 120 , and the first cover plate 120 is attached to a side of the first electrode 104 away from the first color-changing layer 102 .

[0064] In this embodiment, the first substrate 116 can protect various structures of the color-changing module 100 , prevent the color-changing module 100 from being worn out by external forces, and extend the service life of the color-changing module 100 .

[0065] When the color-changing module 100 is not provided with the first substrate 116, the first color-changing layer 102, the first electrode 104, the second electrode 106, the electron transport layer 108, the thin cathode 110 and the hole transport layer 112 can be prepared on the first cover plate 120, and then the first base color layer 114 is adhered to the second electrode 106 through the second optical adhesive 124, thereby simplifying the preparation process of the color-changing module 100 and improving the preparation efficiency of the color-changing module 100.

[0066] According to some embodiments of the present application, Fig. 9 , Fig.10 and Fig.11 As shown, the color-changing module 100 also includes a second substrate 128 and an insulating layer 130, and the insulating layer 130 is arranged on the second substrate 128; the first color-changing layer 102 includes a plurality of color-changing components 132, and the plurality of color-changing components 132 are arranged in an array on the insulating layer 130; the number of the first electrodes 104 is multiple; the number of the second electrodes 106 is multiple; the plurality of first electrodes 104, the plurality of second electrodes 106 and the plurality of color-changing components 132 correspond to each other and are arranged in parallel along the second substrate 128.

[0067] In this embodiment, the first color-changing layer 102 includes a plurality of color-changing components 132, and the plurality of color-changing components 132 are arranged in an array on the insulating layer 130. The plurality of first electrodes 104, the second electrodes 106 and the plurality of color-changing components 132 correspond to each other and are arranged in parallel along the second substrate 128, so that each color-changing component 132 can be individually color-changed, thereby realizing local control of the color-changing module 100, and making the control of the color-changing module 100 more refined. In addition, by making the plurality of first electrodes 104, the second electrodes 106 and the plurality of color-changing components 132 correspond to each other and are arranged in parallel along the second substrate 128, the space occupied by the first electrodes 104, the second electrodes 106 and the plurality of color-changing components 132 in the thickness direction of the color-changing film group is reduced, thereby reducing the thickness of the color-changing module 100, which is conducive to the lightness and thinness of the color-changing module 100.

[0068] Specifically, through semiconductor technology, different color-changing components 132 can be prepared on the same second substrate 128 to achieve a color display effect of a liquid crystal display (LCD) or an organic semiconductor display (OLED).

[0069] The scheme of arranging the array type color changing component 132 on the second substrate 128 is suitable for various color changing modes such as organic electrochromic, inorganic electrochromic, polymer dispersed liquid crystal, etc., and the electrode can be selected from a variety of conductive metals, and the second substrate 128 is universal.

[0070] Further, the first electrode 104 and the second electrode 106 are pixel electrodes 158 .

[0071] Specifically, Fig.12 As shown, the color changing component 132 includes a blue display portion 164 , a red display portion 166 and a green display portion 168 .

[0072] According to some embodiments of the present application, Fig. 9 As shown, each color-changing component 132 in the multiple color-changing components 132 includes an electrochromic film 134, an electrolyte film 136 and a charge storage film 138; the electrochromic film 134 is in contact with the first electrode 104; the first side of the electrolyte film 136 is in contact with the electrochromic film 134; the charge storage film 138 is in contact with the second side of the electrolyte film 136 and is in contact with the second electrode 106; wherein the electrochromic film 134, the electrolyte film 136 and the charge storage film 138 are arranged in parallel along the second substrate 128.

[0073] In this embodiment, the color-changing component 132 includes an electrochromic film 134, an electrolyte film 136, and a charge storage film 138, so that after a certain voltage is applied to the first electrode 104 and the second electrode 106, the color-changing component 132 can display a corresponding color, further improving the color diversity of the color-changing module 100. In addition, since the electrochromic film 134, the electrolyte film 136, and the charge storage film 138 are arranged in parallel along the second substrate 128, the space occupied by the electrochromic film 134, the electrolyte film 136, and the charge storage film 138 in the thickness direction of the color-changing film group is reduced, thereby reducing the thickness of the color-changing module 100, which is conducive to the lightness and thinness of the color-changing module 100.

[0074] Furthermore, the second substrate 128 may be a transparent substrate or an opaque substrate.

[0075] The second substrate 128 can be various transparent or opaque substrates such as a glass substrate, a silicon wafer, a plastic substrate, etc. The color-changing module 100 can be directly applied or attached to a transparent carrier such as glass, a mobile phone cover, etc.

[0076] The pixel electrode 158 may be made of indium tin oxide or other conductive metals, and may be a transparent electrode or an opaque electrode.

[0077] Further, when preparing the color-changing module 100, a light shielding layer 142, an insulating layer 130, a semiconductor layer 146, a dielectric layer 148, a gate 150, a protective layer 152, a source and drain electrode 154, a passivation layer 156 and a pixel electrode 158 can be sequentially prepared on the second substrate 128 according to a semiconductor process, wherein the pixel electrode 158 is a conductive layer of the color-changing module 100; an electrochromic film 134, an electrolyte film 136 and a charge storage film 138 are sequentially prepared on both sides of the conductive layer, and a transparent protective layer 160 is covered on the electrochromic film 134, the electrolyte film 136 and the charge storage film 138. The electrochromic film 134 and the charge storage film 138 are in contact with the pixel electrode 158.

[0078] According to some embodiments of the present application, Fig.10 As shown, each of the multiple color-changing components 132 includes a polymer dispersed liquid crystal (PDLC) module 140, a first side of the polymer dispersed liquid crystal module 140 contacts the first electrode 104, and a second side of the polymer dispersed liquid crystal module 140 contacts the second electrode 106.

[0079] In this embodiment, the color-changing component 132 includes a polymer dispersed liquid crystal module 140, a first side of the polymer dispersed liquid crystal module 140 contacts the first electrode 104, and a second side contacts the second electrode 106. The polymer dispersed liquid crystal module 140 can switch between a mist state and a transparent state under the action of the first electrode 104 and the second electrode 106, thereby realizing fine control of the atomization or transparency of the color-changing module 100. By attaching a film 182 color film to the second substrate 128, the change between color, transparency and mist can be realized.

[0080] Furthermore, when preparing the color-changing module 100, a light-shielding layer 142, an insulating layer 130, a semiconductor layer 146, a dielectric layer 148, a gate 150, a protective layer 152, a source and drain electrode 154, a passivation layer 156 and a pixel electrode 158 are sequentially prepared on the second substrate 128 according to a semiconductor process, wherein the pixel electrode 158 is a conductive layer of the color-changing module 100; a polymer dispersed liquid crystal film layer is prepared in the middle position of the conductive layer, and a transparent protective layer 160 is covered on the pixel electrode 158 and the polymer dispersed liquid crystal film layer, wherein the pixel electrode 158 contacts the polymer dispersed liquid crystal film layer and provides a voltage at both ends.

[0081] According to some embodiments of the present application, Fig.13 and Fig.14 As shown, the color changing module 100 further includes a plurality of first control modules 162 . The plurality of first control modules 162 are disposed on the insulating layer 130 and are respectively connected to the plurality of first electrodes 104 .

[0082] In this embodiment, by setting a first control module 162 corresponding to the first motor, each color-changing component 132 can be individually controlled, so that the color-changing module 100 can achieve local color change, further improving the refinement of the control of the color-changing module 100.

[0083] Furthermore, a transparent protective layer 160 is deposited on the color-changing component 132 or the polymer dispersed liquid crystal module 140 , thereby reducing the probability of edge failure of the color-changing module 100 due to edge water vapor penetration.

[0084] Specifically, the first control module 162 can be a thin film transistor (TFT) switch or a field effect transistor (TFT) switch. The thin film transistor switch or the field effect transistor switch realizes the control of the color changing component 132, so that the multiple color changing components 132 form an integrated high-density micro-sized array on the second substrate 128, and each color changing component 132 can be addressed and lit separately, reducing the pixel point distance from the entire surface to the micron level.

[0085] The thin film transistor or field effect transistor includes but is not limited to a top gate structure, and may also adopt a bottom gate, a coplanar structure, etc.

[0086] According to some embodiments of the present application, Fig.15 and Fig.16 As shown, the color-changing module 100 further includes a second color-changing layer 170 and a third electrode 172 ; the second color-changing layer 170 is located on a side of the first electrode 104 away from the first color-changing layer 102 ; the third electrode 172 is located on a side of the second color-changing layer 170 away from the first electrode 104 .

[0087] In this embodiment, the color-changing module 100 further includes a second color-changing layer 170 and a third electrode 172, and the third electrode 172 and the first electrode 104 are respectively located on both sides of the second color-changing layer 170, and then a voltage is applied to the second color-changing layer 170 through the first electrode 104 and the third electrode 172 to control the second color-changing layer 170. In addition, the first color-changing layer 102 and the second color-changing layer 170 share the first electrode 104, which simplifies the structure of the color-changing module 100 and reduces the thickness of the color-changing module 100.

[0088] According to some embodiments of the present application, Fig.15 and Fig.16 As shown, the first color-changing layer 102 is an electrochromic layer, and the second color-changing layer 170 is a polymer dispersed liquid crystal layer.

[0089] In this embodiment, the first color-changing layer 102 is an electrochromic layer, and the first color-changing layer 102 can change color under the action of the first electrode 104 and the second electrode 106. The second color-changing layer 170 is a polymer dispersed liquid crystal layer, and the second color-changing layer 170 can switch between a transparent state and an atomized state under the action of the first electrode 104 and the third electrode 172. By arranging the electrochromic layer and the polymer dispersed liquid crystal layer in the color-changing module 100, dual color depth control can be achieved. According to the subtractive principle of color, by adjusting the depth of the two primary colors, richer color changes can be achieved.

[0090] By setting an electrochromic layer and a polymer dispersed liquid crystal layer, the color-changing module 100 realizes a controllable multi-color color-changing function, and the polymer dispersed liquid crystal layer is located on the upper layer of the electrochromic layer. Because the polymer dispersed liquid crystal layer can absorb ultraviolet light, it can reduce the damage of ultraviolet light to the electrochromic layer and improve the service life of the electrochromic layer.

[0091] Specifically, the electrochromic layer is controlled by the electric field generated by the first electrode 104 and the second electrode 106. When the level of the second electrode 106 is greater than 0V, the specific voltage depends on the specifications of the electrochromic layer, preferably 1.2V, and the electrochromic layer is in the coloring process. When the second electrode 106 is less than 0V, the specific voltage depends on the specifications of the electrochromic layer, preferably -1.2V, and the electrochromic layer is in the fading process; or when the level of the second electrode 106 is greater than 0V, the specific voltage depends on the specifications of the electrochromic layer, preferably 1.2V, and the electrochromic layer is in the fading process. When the second electrode 106 is less than 0V, the specific voltage depends on the specifications of the electrochromic layer, preferably -1.2V, and the electrochromic layer is in the coloring process.

[0092] The polymer dispersed liquid crystal layer is controlled by the first electrode 104 and the third electrode 172. The electric field generated by the first electrode 104 and the third electrode 172 is in a non-driven state. The polymer dispersed liquid crystal layer scatters the incident light, making the color-changing module 100 appear foggy. After being driven by positive and negative square waves, the polymer dispersed liquid crystal layer appears transparent, allowing light to pass through.

[0093] The first electrode 104 is always at 0V level.

[0094] According to some embodiments of the present application, Fig.15 and Fig.16 As shown, the color-changing module 100 further includes a first resin plate 174 and a second cover plate 176 ; the first resin plate 174 is attached to a side of the third electrode 172 away from the second color-changing layer 170 ; and the second cover plate 176 is attached to the first resin plate 174 .

[0095] In this embodiment, by providing the first resin plate 174 and the second cover plate 176 , the protection of each layer structure of the color-changing module 100 is achieved, the probability of the color-changing film group being damaged by external forces is reduced, and the service life of the color-changing module 100 is thereby increased.

[0096] Specifically, the first resin plate 174 is attached to the second cover plate 176 via the third optical adhesive 188 .

[0097] Specifically, the first resin plate 174 is a polyethylene terephthalate (PET) plate.

[0098] According to some implementations of this application, for example Fig.15 and Fig.16 As shown, the color-changing module 100 further includes a second resin plate 178 , and the second resin plate 178 is disposed between the second color-changing layer 170 and the first electrode 104 .

[0099] In this embodiment, by disposing the second resin plate 178 between the second color-changing layer 170 and the first electrode 104 , support for the color-changing module 100 can be achieved, thereby improving the strength of the color-changing module 100 .

[0100] According to some embodiments of the present application, Fig.15 and Fig.16 As shown, the color-changing module 100 also includes a third resin plate 180, a film sheet 182 and a third base color layer 184. The first side of the third resin plate 180 is adhered to the side of the second electrode 106 away from the first color-changing layer 102; the first side of the film sheet 182 is adhered to the second side of the third resin plate 180; and the third base color layer 184 is adhered to the second side of the film sheet 182.

[0101] In this embodiment, the color changing module 100 also includes a film 182 and a third base color layer 184 . When the first color changing layer 102 and the second color changing layer 170 are both in a transparent state, the color of the color changing module 100 is the color of the third base color layer 184 , further enriching the color of the color changing module 100 .

[0102] Furthermore, by setting a third resin plate 180, the second electrode 106, the first color-changing layer 102 and the first electrode 104 can be prepared in sequence on the third resin plate 180, and the second color-changing layer 170 and the third electrode 172 can be prepared at one time on the second resin plate 178, and then the two groups of structures are bonded together to the first resin plate 174 and the second cover plate 176, thereby reducing the material requirements for each layer of the structure and reducing the cost of the color-changing module 100.

[0103] The third resin plate 180 may not be provided, and each layer structure is supported on both sides of the second resin plate 178 , thereby reducing the thickness of the color-changing module 100 and simplifying the preparation process of the color-changing module 100 .

[0104] Specifically, the third resin plate 180 is bonded to the film sheet 182 via the fourth optical adhesive 190 .

[0105] According to some embodiments of the present application, Fig.15 and Fig.16 As shown, the color changing module 100 further includes a second control module 186 , and the second control module 186 is electrically connected to the second electrode 106 and the third electrode 172 , respectively.

[0106] In this embodiment, the second control module 186 is provided, and the second control module 186 is connected to the second electrode 106 and the third electrode 172 respectively, so as to control the first color-changing layer 102 and the second color-changing layer 170 .

[0107] The first color-changing layer 102 and the second color-changing layer 170 are integrated by sharing the first electrode 104 to realize a controllable multi-color color-changing function. The first color-changing layer 102 and the second color-changing layer 170 are driven and controlled by outputting positive and negative voltages through the second control module 186 .

[0108] like Fig.17 and Fig.18 As shown, in order to ensure that the first electrode 104 is always at a 0V level, taking a root mean square (RMS) of 24V as an example, the driving method of the third electrode 172 is as follows: Fig.17 The driving waveform shown and Fig.18 The driving waveform is shown.
