The quantum dot luminescent shell device 100 includes a shell 110, a light source L, a power supply device 113, a quantum dot pattern layer 114 and a transparent light guide layer 115. The housing 110 includes a top portion 111 and a side portion 112 . The peripheral portion 112 extends downward around the edge of the top portion 111 and forms a covering space S. The light source L is provided in the peripheral side portion 112 . The power supply device 113 is disposed in the peripheral portion 112 and is electrically connected to the light source L. The transparent light guide layer 115 is formed on the top 111 of the housing 110 . The quantum dot pattern layer 114 is formed above or below the transparent light guide layer 115 and includes a plurality of arranged quantum dots 200 . The light source L receives power from the power supply device 113 and emits a light.

One of the colors inspires light.

The structure of the power supply device 113 is not particularly limited. In this embodiment, the power supply device 113 is disposed in the peripheral portion 112 of the housing 100. It can use a flat micro battery 113a combined with a battery holder 113b connected to the circuit board to match the thin and light housing 110.

The material of the transparent light guide layer 115 may include PMMA (polymethylmethacrylate) resin, COP (cycloolefin polymer), PC (polycarbonate), glass Or metal, etc., its purpose is to use the principle of total reflection of light to guide the direction of light to improve the luminous brightness and control the uniformity of luminous brightness. At the same time, the excitation efficiency of the light source L to the plurality of quantum dots 200 in the quantum dot pattern layer 114 can also be increased. As shown in Figures 3 and 4, the transparent light guide layer 115 can be directly formed on the top 111 of the housing 110 when the housing 110 is produced. In other words, the top 111 of the housing 110 can itself be the transparent light guide layer 115. Or the transparent light guide layer 115 is made inside. Alternatively, as shown in FIGS. 5 and 6 , the prefabricated housing 110 is used, and the transparent light guide layer 115 is formed above or below the top 111 of the housing 110 . This provides process flexibility and wider applicability.

Since the light guide direction of the transparent light guide layer 115 is adjustable, the quantum dot pattern layer 114 can also be disposed above or below the transparent light guide layer 115 according to different needs, depending on the light guide direction. In Figures 3 and 5, the quantum dot pattern layer 114 is located above the transparent light guide layer 115; in Figures 4 and 6, the quantum dot pattern layer 114 is located below the transparent light guide layer 115.

The light source L can use a plurality of light-emitting diodes arranged around the transparent light guide layer 115, and the light color emitted by the light source L can include purple, blue or white. When the light color emitted by the light source L is white, it may be composed of red, green and blue.

The plurality of quantum dots 200 can each have the same or different colors, and their colors can be modulated in accordance with the light color emitted by the light source L, so that the excitation light forms a full-color light color.

For example, the colors of the quantum dots 200 may include red, green, and blue, and the color of each quantum dot 200 corresponds to the color of light emitted by the light-emitting diode of each light source L. Alternatively, the light color emitted by the multiple light-emitting diodes of the light source L is single blue or purple. In this case, the color of the multiple quantum dots 200 can be Contains red and green.

Quantum dots 200 are small semiconductor crystals with dimensions as low as nanometers. Their properties are very different from bulk semiconductors. The most notable feature of quantum dots 200 is the ability to adjust the semiconductor band gap by changing their size and discrete energy levels (the so-called Quantum Confinement Effect). Based on the narrow emission linewidth of the quantum dots 200 (for example, the emission half-maximum (FWHM) is about 20 to 30 nanometers), a narrower spectrum can be obtained. Extremely high brightness and color saturation can be achieved through the narrow spectrum.

The material of the quantum dot 200 may include inorganic materials, such as II-VI element compounds, III-V element compounds, perovskite quantum dots, the above II-VI element compounds and/or III-V elements. Core-shell structure compounds formed by compound coating or doped nanocrystalline particles. Among them, II-VI group elements may include cadmium selenide (CdSe), cadmium telluride (CdTe), magnesium sulfide (MgS), magnesium selenide (MgSe), magnesium telluride (MgTe), calcium sulfide (CaS), selenium Calcium sulfide (CaSe), calcium telluride (CaTe), strontium sulfide (SrS), strontium selenide (SrSe), strontium telluride (SrTe), barium sulfide (BaS), barium selenide (BaSe), barium selenide (BaTe) ), zinc sulfide (ZnS), zinc selenide (ZnSe), zinc telluride (ZnTe) or cadmium sulfide (CdS), etc.; III-V element compounds may include gallium nitride (GaN), gallium phosphide (GaP) , gallium arsenide (GaAs), indium nitride (lnN), indium phosphide (lnP) or indium arsenide (InAs), etc., but are not limited to the above materials.

The plurality of quantum dots 200 can be of red, green, blue, or any combination of the foregoing colors. The quantum dots 200 can be in the form of particles, and the diameter of the particles can be between 1 nanometer and 10 nanometers. The stacked arrangement of quantum dots 200 can be formed by methods such as screen printing, offset printing, direct injection printing, thermal transfer printing, thermal sublimation, inkjet (Inject), Chemical colloidal method, self-assembly method, lithography and etching or split-gate approach, etc. Through chemical sol synthesis, multilayered quantum dots 200 can be produced. The process is simple and suitable for mass production. The self-assembly method can use a chemical vapor deposition process to allow the quantum dots 200 to self-grow on the surface of a specific substrate, thereby mass-producing regularly arranged quantum dots 200. Lithography and etching uses a light beam or electron beam to directly etch a substrate to create the desired pattern. The split-gate approach generates two-dimensional localization on the two-dimensional quantum well plane by applying an external voltage, which can change the shape and size of the quantum dots 200.

The size of the light emitting diode of the light source L can be millimeters or less, preferably micron size. Using smaller size and larger number of light-emitting diodes can make the light emitted by the light source L more uniform and concentrated.

In the present invention, the original quantum dot pattern layer 114 can form uniform surface luminescence, but more preferably, through the characteristics of the transparent light guide layer 115, the light emitted by the light source L can be guided and concentrated by the transparent light guide layer 115. Light is emitted toward the quantum dot pattern layer 114 more uniformly, greatly increasing the color saturation and brightness uniformity of the light emitting pattern formed by the quantum dot pattern layer 114 . Then, by exciting the characteristics of the excitation light converted by the quantum dots 200, the color, contrast and brightness of the luminous pattern formed by the quantum dot pattern layer 114 are increased, so as to obtain a conspicuous luminous pattern, enhance the recognition and aesthetics of the logo, and greatly enhance the quantum The texture and application value of the light-emitting casing device 100 are highlighted.

The quantum dot luminous shell device 100 of the present invention has a wide range of applications The size and size of the field and the covering space S within it can be designed to correspond to the sizes or sizes of various commonly used mobile phones or tablet computers. Therefore, it can be placed on the back panel of a mobile phone or tablet. In addition to providing general cushioning and shock-proof effects, it can also meet modern people's pursuit of aesthetic quality and provide high brightness, high color saturation and high uniformity for personalized recognition.
