Fig. 1 is a sectional view of the present invention.

The reference signs are: the packaging structure comprises a color coating layer 1, first ITO conductive glass 2, an ITO Film or glass cover plate LENS 3, a packaging structure layer 4, a packaging frame 41, liquid crystal microspheres 4, second ITO conductive glass 5, a photochromic layer 6 and an ultraviolet light emitting layer 7.

Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and the accompanying fig. 1, which are not intended to limit the present invention.

Referring to fig. 1, the active color-changing display mobile phone glass rear cover comprises a color Film coating layer 1, a first ITO conductive glass 2, an ITO Film or glass cover plate LENS 3, an encapsulation structure layer 4, a second ITO conductive glass 5, a photochromic layer 6 and an ultraviolet light emission layer 7 which are sequentially attached from top to bottom, wherein the encapsulation structure layer 4 comprises an encapsulation frame 41 and a plurality of liquid crystal microspheres 42 filled in the encapsulation frame 41.

The utility model discloses a lid is through adopting the last colored coating Film layer 1, first ITO conductive glass 2, ITO Film or the glass apron LENS 3, packaging structure layer 4, the conductive glass of second ITO 5, photochromism layer 6 and the ultraviolet ray emission layer 7 of down laminating in proper order behind the cell-phone glass, can realize the change of lid colour behind the cell-phone glass to the variable colour's of user experience is given in the area.

In this embodiment, the photochromic layer 6 is a photochromic layer 6 sensitive to 200-400nm ultraviolet light. Correspondingly, the ultraviolet light emitting layer 7 is an LED light source emitting light in 200-400nm ultraviolet spectrum. The photochromic layer 6 will change color when irradiated by 200-400nm ultraviolet light.

The utility model discloses a lid realizes that the principle of colour change is as follows behind the cell-phone glass:

1. the reflectivity of the color coating layer is assumed to be R1, and the transmittance is assumed to be T1; the photochromic layer 6 has a reflectivity of R2;

2. the liquid crystal microspheres 42 allow light to pass through under the action of the electric field, and the light passing rate is t. In the absence of an electric field, the liquid crystal microspheres 42 completely do not allow light to pass through or have a low pass rate, which can be ignored;

3. the first ITO conductive glass 2 is a conductive layer for realizing the application of an electric field E;

4. under the condition that the electric field E is not applied, the liquid crystal microspheres 42 do not allow visible light to pass through, and the light entering the human eyes is only the reflected light of the color coating layer (for convenience of explanation, the reflection of the first ITO conductive glass 2, the ITO Film or the glass cover plate LENS 3 is not considered, and the transmittance of the first ITO conductive glass 2, the ITO Film or the glass cover plate LENS 3 is assumed to be 100%), the color is of course the reflection spectrum color of the color coating layer, and the intensity entering the human eyes is L1R 1(L1 is the initial intensity of the incident light);

5. under the condition of applying an electric field E, the liquid crystal microspheres 42 allow visible light to pass through, the passing rate is t, and the light entering human eyes is the mixed light of the reflected light of the color coating layer and the light reflected by the photochromic layer 6 after penetrating through the color coating layer 1, the first ITO conductive glass 2, the ITO Film or the glass cover plate LENS 3; the reflected light intensity of the colored Film coating layer 1 is L1R 1, the light reflected by the photochromic layer 6 penetrates through the colored Film coating layer 1, the first ITO conductive glass 2, the ITO Film or the glass cover plate LENS 3, the intensity is L2R 2T 1, the color perceived by human eyes is the mixed color of the colored Film coating layer 1 and the photochromic layer 6, and the two lights are mixed according to different intensities to present different colors;

6. when the photochromic layer 6 is irradiated by 200-plus 400nm ultraviolet light, the color changes, so that the ultraviolet irradiation source can be used for receiving the ultraviolet irradiation source, the transmittance of the liquid crystal microspheres 42 is changed under the action of an electric field, the ambient ultraviolet light from the outside is emitted, and the ultraviolet light emitting layer 7 emits an LED light source with 200-plus 400nm ultraviolet spectrum, so that the color of the photochromic layer 6 can be actively controlled, and the mixed color of the photochromic layer and the color coating layer can be actively controlled, so that human eyes can see the variable color.

The above-mentioned embodiment is the utility model discloses the implementation of preferred, in addition, the utility model discloses can also realize by other modes, not deviating from the utility model discloses any obvious replacement is all within the protection scope under the prerequisite of design.
