Description

Technical Field

[0001] This application relates to the field of electronic devices, and in particular to an electronic device. Background Technology

[0002] With the rapid iteration and development of electronic devices, more and more electronic devices are equipped with camera modules to realize image shooting functions, and more and more electronic devices are equipped with fill light modules, which are turned on in relatively dark environments (such as when shooting night scenes) to provide supplementary light during the shooting process and improve image quality.

[0003] Traditional fill light elements are flash units, which flash briefly to illuminate the shooting environment during shooting to achieve the purpose of fill light. However, in practice, it has been found that turning on the flash can only illuminate a small area in front of the subject, and it cannot guarantee the balance of light and shadow in night scene shooting. Sometimes, it can only illuminate the basic appearance of the subject, resulting in poor overall image quality. Summary of the Invention

[0004] The electronic device provided in this application can adaptively provide different supplementary lighting solutions during the shooting process to improve the overall image quality of the captured image.

[0005] The electronic device provided in this application includes:

[0006] The light-emitting module is used to emit supplementary light.

[0007] A dimming module is disposed on the light-emitting side of the light-emitting module. The dimming module includes a light control unit. Along the light-emitting direction of the light-emitting module, the projection of the light-emitting module and the projection of the light control unit at least partially overlap. The supplementary light passes through the light control unit.

[0008] The light control unit has a first circuit connection state and a second circuit connection state.

[0009] The electronic device described above, wherein the light control unit comprises:

[0010] The housing has a first wall and a second wall opposite each other along the light-emitting direction of the light-emitting module, and at least one of the first wall and the second wall is an electrode plate;

[0016] The second circuit is in a power-off state, the charged staining molecules are dissolved in the solution, the supplementary light irradiates the charged staining molecules and the charged staining molecules emit fluorescence to form scattered light.

[0017] In the electronic device described above, when the power-on state is at a first voltage, all the charged staining molecules adsorb and aggregate on the surface of the electrode plate, generating a fluorescence aggregation-induced quenching phenomenon and not emitting fluorescence.

[0018] When the applied voltage is the second voltage, more than half of the charged staining molecules adsorb and aggregate on the surface of the electrode plate, generating fluorescence aggregation-induced quenching. The supplementary light irradiates the charged staining molecules that are not aggregated on the electrode plate and emits first red fluorescence.

[0019] When the voltage applied is the third voltage, less than half of the charged staining molecules adsorb and aggregate on the surface of the electrode plate, resulting in fluorescence aggregation-induced quenching. The supplementary light irradiates the charged staining molecules that are not aggregated on the electrode plate and emits a second red fluorescence.

[0020] In the power-off state, all the charged staining molecules dissolve in the solution, and the supplementary light irradiates the charged staining molecules and emits a third red fluorescence;

[0021] The first voltage is greater than the second voltage, and the second voltage is greater than the third voltage;

[0022] The intensity value of the first red fluorescence is less than the intensity value of the second red fluorescence, and the intensity value of the second red fluorescence is less than the intensity value of the third red fluorescence.

[0025] The second circuit is connected in an energized state.

The supplementary light irradiates the charged staining molecules and the charged staining molecules emit fluorescence.

[0026] In the electronic device described above, the solution is a homogenizing solvent used to promote the uniform dissolution and diffusion of charged staining molecules.

[0027] The electronic device described above, wherein the solution contains neutralizing ions, the charge of which is opposite in polarity to the charge of the charged staining molecules;

[0028] The first wall is a first electrode plate, and the second wall is a second electrode plate. In the energized state, the first electrode plate and the second electrode plate have opposite polarities. The first electrode plate is used to adsorb the charged staining molecules, and the second electrode plate is used to adsorb the neutralizing ions.

[0029] In the electronic device described above, the distance between the first wall and the light-emitting module is less than the distance between the second wall and the light-emitting module.

[0030] In the electronic device described above, the light control unit further includes a first transparent substrate and a second transparent substrate, the first transparent substrate being covered and connected to the first wall, the second transparent substrate being covered and connected to the second wall, and the light-emitting module being connected to the side of the first transparent substrate away from the first wall.

[0031] The electronic device described above, wherein the light-emitting module includes:

[0032] A light-concentrating element has a light guide groove recessed on one side surface facing the dimming module. The opening of the light guide groove faces the dimming module, and the light guide groove gradually expands along the direction from the bottom of the light guide groove to the opening of the light guide groove. The groove wall of the light guide groove forms a first reflective surface.

[0033] The light source is located at the bottom of the light guide groove;

[0034] A reflective element, at least a portion of which is inserted into the light guide groove through the slot, is gradually expanded along the direction from the bottom of the light guide groove to the opening of the light guide groove, and a second reflective surface is formed on one side surface of the reflective element facing the light guide groove. A reflective annulus is formed between the first reflective surface and the second reflective surface, and an annular light outlet is formed between the reflective element and the edge of the opening of the light guide groove.

[0035] In the electronic device described above, the first reflective surface and the second reflective surface are smooth arc surfaces;

[0036] And / or, the first reflective surface and the second reflective surface are provided with wavy or sawtooth reflective patterns.

By setting a light control unit in the dimming module and enabling the light control unit to have a first circuit connection state and a second circuit connection state, in the first circuit connection state, the dimming module and the light-emitting module cooperate to emit direct light, providing a more focused and brighter light for fill light. In the second circuit connection state, the dimming module and the light-emitting module cooperate to emit diffused light, providing a more uniform and softer light for fill light, so as to adapt to the fill light needs in different shooting environments, provide different fill light solutions, and improve the overall image quality of the captured image.

[0048] The embodiments of this application will now be described in detail. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0049] like Figure 1 As shown, the electronic device provided in this application includes a light-emitting module 1 and a dimming module 2.

[0050] The light-emitting module 1 is used to emit supplementary light; the dimming module 2 is used to adjust the supplementary light to provide different light emission modes to meet different supplementary lighting needs.

[0051] The dimming module 2 is located on the light-emitting side of the light-emitting module 1. The dimming module 2 is connected to the light-emitting module 1 to shorten the propagation path of light between the two and reduce light loss.

[0052] The dimming module 2 includes a light control unit 21. Along the light emission direction of the light emission module 1, the projection of the light emission module 1 and the projection of the light control unit 21 at least partially overlap. At the position where the projections of the light emission module 1 and the light control unit 21 overlap, the supplementary light can pass smoothly through the light control unit 21 to adjust the supplementary light and obtain different supplementary light schemes.

[0053] The light control unit 21 has a first circuit connection state and a second circuit connection state. In the first circuit connection state, the light control unit 21 is used to collimate the fill light rays to form direct light, providing more focused and brighter light for fill light. In the second circuit connection state, the light control unit 21 is used to diverge the fill light rays to form diffused light, providing more uniform and softer light for fill light. This adapts to the fill light needs in different shooting environments, providing different fill light solutions to improve the overall image quality of the captured image.

[0054] There are four main types of existing dimming technologies: polymer dispersed liquid crystal (PDLC), suspended particle device (SPD), dichroic dye liquid crystal (DDLC), and electrochromism (EC). Compared with the four existing dimming technologies, the dimming module 2 in this application can effectively improve the dimming speed, dimming color, and supplementary light, as detailed in Table 1 below.

[0055]

[0056]

[0057] Table 1

[0058] The following will describe this application in detail with reference to Table 1 above.

[0059] like Figure 1 As shown, the electronic device provided in this application includes a light control unit 21 comprising a housing 211, a solution 212, and charged staining molecules 213.

[0060] The housing 211 includes a first wall 2111, a second wall 2112, and a peripheral wall 2113. The first wall 2111 and the second wall 2112 are parallel to each other and are arranged opposite to each other and spaced apart along the light emission direction of the light emission module 1. The peripheral wall 2113 is an annular frame or cylindrical structure that is through the light emission direction of the light emission module 1. The first wall 2111 is sealed to one end of the peripheral wall 2113 along the light emission direction, and the second wall 2112 is sealed to the other end of the peripheral wall 2113 along the light emission direction. The first wall 2111, the second wall 2112, and the peripheral wall 2113 enclose a sealed cavity.

[0061] Optionally, the peripheral wall 2113 is made of structural adhesive and is bonded and fixed to the first wall 2111 and the second wall 2112 respectively, effectively ensuring the sealing performance of the shell 211.

[0062] At least one of the first wall 2111 and the second wall 2112 is an electrode plate; when energized, the electrode plate carries a charge and can attract or repel charged particles.

[0063] Solution 212 fills the interior of housing 211; charged dyeing molecules 213 are disposed inside housing 211 and dissolved in solution 212. Optionally, solution 212 fills the space inside housing 211. In the first circuit connection state, this allows charged dyeing molecules 213 to be uniformly dissolved and distributed inside housing 211. In the second circuit connection state, this allows charged dyeing molecules 213 to be quickly and uniformly adsorbed and deposited on the surface of the electrode plate, ensuring that the supplementary light emitted to any position of the light control unit 21 can pass through the gathered charged dyeing molecules 213, thereby achieving adjustment of the supplementary light.

[0064] In the first circuit connection state, the charge on the charged dyeing molecule 213 is opposite in polarity to the charge on the electrode plate. Thus, by adjusting the circuit connection state of the light control unit 21, the electrode plate can adsorb the charged dyeing molecule 213, thereby achieving the effect of adjusting the supplementary light mode.

[0065] like Figures 1 to 5 As shown, the electronic device provided in this application includes a light-emitting module 1 comprising a light-concentrating element 11, a light source 12, and a reflective element 13.

[0066] A light guide groove is recessed on the side surface of the light-concentrating element 11 facing the dimming module 2. The opening of the light guide groove faces the dimming module 2, and the light guide groove gradually expands along the direction from the bottom of the light guide groove to the opening of the light guide groove. The groove wall of the light guide groove forms a first reflective surface 111. At least a portion of the reflective element 13 is inserted into the light guide groove through the opening. The reflective element 13 gradually expands along the direction from the bottom of the light guide groove to the opening of the light guide groove. The side surface of the reflective element 13 facing the light guide groove forms a second reflective surface 131. A reflective ring 14 is formed between the first reflective surface 111 and the second reflective surface 131. An annular light outlet is formed between the reflective element 13 and the edge of the opening of the light guide groove.

[0067] The light source 12 is located at the bottom of the light guide groove. The light emitted by the light source 12 is repeatedly reflected in a zigzag pattern between the first reflecting surface 111 and the second reflecting surface 131 in the reflection ring 14, changing its propagation direction until it reaches the dimming module 2 from the light outlet. This is equivalent to converting the point light source 12 into a ring light source 12, effectively increasing the light-emitting area and making full use of the light emitted by the light source 12.

[0068] Optionally, in the electronic device provided by this application, the first reflective surface 111 and the second reflective surface 131 are smooth arc surfaces. Optionally, the first reflective surface 111 and the second reflective surface 131 are provided with corrugated or sawtooth reflective patterns. This not only achieves light focusing but also improves the collimation of the emitted light, increases light utilization, and makes zoom adjustment possible.

[0069] like Figures 1 to 5As shown, in the electronic device provided by this application, the focusing element 11 and the dimming module 2, as well as the reflector 13 and the dimming module 2, are bonded and fixed by an adhesive layer 3. This securely connects the focusing element 11 and the reflector 13 to the dimming module 2, minimizing the propagation path of the supplementary light, improving light utilization, and reducing light loss.

[0070] Optionally, the charged staining molecule 213 can be a quantum dot, an organic fluorescent dye, or a conventional luminescent dye.

[0071] Optionally, such as Figure 2 and Figure 3 As shown, in the electronic device provided in this application, the charged staining molecule 213 is an aggregation-induced quenching staining molecule, which is a traditional planar luminescent molecule. When the aggregation-induced quenching staining molecule is dissolved in solution 212 into a single molecule state, it often exhibits strong fluorescence, but its luminescence weakens or even disappears after aggregation. This phenomenon is called concentration quenching effect or aggregation-induced quenching (ACQ).

[0072] like Figure 2 As shown, the first circuit is connected in an energized state. Charged dyeing molecules 213 are adsorbed and aggregated on the surface of the electrode plate, and at least partially produce fluorescence aggregation-induced quenching. The supplementary light beam is collimated and passes through the dimming module 2 to form direct light. Specifically, the light-emitting module 1 and the dimming module 2 are energized simultaneously. The light source 12 emits supplementary light beams, which are reflected by the first reflective surface 111 and the second reflective surface 131 and collimated and emitted from the light outlet. At the same time, the electrode plate is energized and carries a charge with a polarity opposite to that of the aggregation-induced quenching dyeing molecules. This causes the aggregation-induced quenching dyeing molecules to aggregate and adsorb on the electrode plate, resulting in fluorescence aggregation-induced quenching. When the supplementary light beam irradiates, it does not emit fluorescence. The supplementary light beam can be collimated and emitted, and the emitted supplementary light spot exhibits the characteristics of high brightness, high beam, and concentrated brightness.

[0073] like Figure 3As shown, the second circuit is in a de-energized state. The charged dyeing molecule 213 dissolves in the solution 212. The supplementary light irradiates the charged dyeing molecule 213, and the charged dyeing molecule 213 emits fluorescence to form scattered light. Specifically, the light-emitting module 1 is powered on, and the light source 12 emits supplementary light. The supplementary light is reflected by the first reflective surface 111 and the second reflective surface 131 and is collimated out of the light outlet. At the same time, the dimming module 2 is not powered on, the electrode plate does not carry a charge, the aggregation-induced quenching dyeing molecule dissolves in the solution 212, and when the supplementary light passes through the light control unit 21, the aggregation-induced quenching dyeing molecule is irradiated by the supplementary light and is excited to fluoresce. Since the fluorescence emitted by the aggregation-induced quenching dyeing molecule is scattered light, the light emitted from the entire dimming module 2 is scattered soft light, and the emitted supplementary light spot exhibits the characteristics of near light and uniform soft light.

[0074] like Figure 4 As shown, the electronic device provided in this application, when powered on, controls the dispersion and aggregation concentration of charged dye molecules 213 by adjusting the power-on voltage. Combined with the principle of photoluminescence caused by the light source 12 irradiation of the charged dye molecules 213, this allows for adjustment of the emission direction, color, and intensity of the supplementary light. This facilitates the realization of a variable-focus (focus and light intensity at different distances) and customizable color soft light supplementary lighting solution, satisfying the need for upgraded soft light supplementary lighting functions. Compared to existing supplementary breathing lights, it can provide higher brightness and integrate flash functionality.

[0075] The light source 12 can be an LED, which consists of a main blue light plus a part of green light to form a blue light. By adjusting the voltage value of the dimming module 2, different aggregation degrees of the charged dyeing molecules 213 can be achieved, that is, the light emission intensity of the charged dyeing molecules 213 can be controlled. By superimposing the light emission intensity of the charged dyeing molecules 213 with the light emission intensity of the light source 12, different light colors can be achieved by the dimming module 2.

[0076] When the power is applied and the voltage is the first voltage, the charged staining molecules 213 adsorb and aggregate on the surface of the electrode plate, producing a fluorescence aggregation-induced quenching phenomenon and not emitting fluorescence; specifically, when the dimming module 2 is powered by a high voltage, the charged staining molecules 213 aggregate and quench and do not emit light, and the dimming module 2 emits the blue light of the light source 12.

[0077] When the voltage is the second voltage, more than half of the charged staining molecules 213 adsorb and aggregate on the surface of the electrode plate, resulting in fluorescence aggregation-induced quenching. The supplementary light irradiates the charged staining molecules 213 that are not aggregated on the electrode plate and emits the first red fluorescence. Specifically, when the dimming module 2 is powered by the voltage, a large number of charged staining molecules 213 aggregate and quench, and when irradiated by the supplementary light, they only emit a weak red fluorescence. The blue light from the light source 12 superimposed on the weak red light makes the entire dimming module 2 emit green light.

[0078] When the voltage is the third voltage, less than half of the charged staining molecules 213 adsorb and aggregate on the surface of the electrode plate, resulting in fluorescence aggregation-induced quenching. The supplementary light irradiates the charged staining molecules 213 that are not aggregated on the electrode plate and emits a second red fluorescence. Specifically, when the dimming module 2 is powered by a low voltage, some of the charged staining molecules 213 aggregate and quench, and emit some red fluorescence when irradiated by the supplementary light. The blue light from the light source 12 superimposes some red light, causing the entire dimming module 2 to emit yellow or white light.

[0079] In the power-off state, all charged staining molecules 213 dissolve in solution 212. When supplementary light irradiates the charged staining molecules 213, they emit a third red fluorescence. Specifically, when the dimming module 2 is not powered, the charged staining molecules 213 do not aggregate and are uniformly dissolved in the solvent. When irradiated by supplementary light, they emit strong red fluorescence, which covers the blue light of the light source 12, causing the entire dimming module 2 to emit red light.

[0080] Specifically, the first voltage is greater than the second voltage, the second voltage is greater than the third voltage, the first voltage is a high voltage, the second voltage is a medium voltage, and the third voltage is a low voltage. It should be noted that the voltage ranges for the first, second, and third voltages can be determined based on the charged staining molecule 213, with the specific ranges ensuring that different colors of light are emitted according to the above scheme.

[0081] The intensity of the first red fluorescence is less than that of the second red fluorescence, and the intensity of the second red fluorescence is less than that of the third red fluorescence, so as to achieve a color transition.

[0082] like Figure 5 and Figure 6 As shown, the electronic device provided in this application includes a charged staining molecule 213, which is an aggregation-induced emission staining molecule and an organic fluorescent molecule. After dissolving into single molecules in solution 212, it emits almost no light, but its luminescence ability is significantly enhanced in its condensed form (forming aggregates or a solid state). This phenomenon is called aggregation-induced emission (AIE).

[0083] like Figure 5 As shown, the first circuit connection state is the power-off state, the charged dyeing molecules 213 dissolve in solution 212, and the supplementary light beam passes through the dimming module 2 to form direct light. Specifically, when the light-emitting module 1 is powered on, the light source 12 emits supplementary light beams; the supplementary light beams are reflected by the first reflective surface 111 and the second reflective surface 131 and are collimated and emitted directly from the light outlet; at the same time, the dimming module 2 is not powered on, the electrode plates do not carry charge, the aggregation-induced emission dyeing molecules dissolve in solution 212, and do not emit fluorescence when irradiated by supplementary light beams, the supplementary light beams can be collimated and emitted directly, and the emitted supplementary light spot exhibits the characteristics of far-field light, high brightness and concentrated brightness.

[0084] like Figure 6 As shown, the second circuit is in an energized state. Charged dyeing molecules 213 adsorb and aggregate on the surface of the electrode plate, generating fluorescence aggregation-induced emission. Supplemental light irradiates the charged dyeing molecules 213, causing them to emit fluorescence. Specifically, the light-emitting module 1 and the dimming module 2 are energized simultaneously. The light source 12 emits supplemental light, which is reflected by the first reflective surface 111 and the second reflective surface 131 and collimated out through the light outlet. At the same time, the electrode plate is energized and carries a charge with a polarity opposite to that of the aggregation-induced emission dyeing molecules, causing the aggregation-induced emission dyeing molecules to aggregate and adsorb on the electrode plate, resulting in fluorescence aggregation-induced emission. When the supplemental light passes through the light control unit 21, the aggregation-induced emission dyeing molecules are irradiated and excited to fluoresce. Since the fluorescence emitted by the aggregation-induced emission dyeing molecules is scattered light, the light emitted from the entire dimming module 2 is scattered soft light, and the emitted supplemental light spot exhibits near-light and uniform soft light characteristics.

[0085] Optionally, in the electronic device provided by this application, solution 212 is a homogenizing solvent used to promote the uniform dissolution and diffusion of charged staining molecules, such as water and ethanol. Neutralizing ions 214 are dissolved in solution 212, and the charge of the neutralizing ions 214 is opposite in polarity to the charge of the charged staining molecules 213. By canceling out the charge of the charged staining molecules 213 with that of the neutralizing ions 214, the shell 211 is made entirely neutral. Using a homogenizing solvent has the advantages of good dissolution effect and low cost.

[0086] Neutralizing ion 214 is a colorless and transparent ion that allows supplementary light to pass through. This prevents the setting of neutralizing ion 214 from affecting the propagation of light and ensures the dimming effect of supplementary light.

[0087] Optionally, in the embodiments of this application, the first wall 2111 is a first electrode plate, and the second wall 2112 is a second electrode plate. In the energized state, the first electrode plate and the second electrode plate have opposite polarities, and the first electrode plate has opposite polarities to the charged staining molecules 213. The first electrode plate is used to adsorb the charged staining molecules 213. The second electrode plate has opposite polarities to the neutralizing ions 214. The second electrode plate is used to adsorb the neutralizing ions 214.

[0088] Optionally, the distance between the first wall 2111 and the light-emitting module 1 is less than the distance between the second wall 2112 and the light-emitting module 1. That is, the first wall 2111 is located close to the light-emitting module 1, which can effectively reduce the distance between the supplementary light source and the charged dyeing molecules 213 gathered on the first electrode plate from the light outlet, thereby improving the light utilization rate.

[0089] In some embodiments of this application, the good solvent for solution 212 can also be an insulating electrophoresis solution. In this case, only one electrode plate is needed, and there is no need to set up neutralizing ions 214, which can further reduce the processing difficulty and cost of the dimming module 2.

[0090] like Figures 1 to 5 As shown, the electronic device provided in this application includes a light control unit 21 that further comprises a first transparent substrate 22 and a second transparent substrate 23. The first transparent substrate 22 is connected to and covers the first wall 2111, and the second transparent substrate 23 is connected to and covers the second wall 2112. The light-emitting module 1 is connected to the side of the first transparent substrate 22 away from the first wall 2111. The first transparent substrate 22 and the second transparent substrate 23 effectively protect the dimming module 2, preventing scratches on the first electrode plate and the second electrode plate. Simultaneously, the first transparent substrate 22 and the second transparent substrate 23, in conjunction with the peripheral wall 2113 of the dimming module 2, provide insulation for the first electrode plate and the second electrode plate, preventing leakage, short circuits, and other phenomena. Optionally,

[0091] The first transparent substrate 22 and the second transparent substrate 23 can be made of various materials such as glass, polyethylene terephthalate (PET), and polyimide (PI), which have good light transmittance and ensure that the supplementary light can pass through smoothly.

[0092] The electronic device provided in this application includes a light-emitting module 1 and a dimming module 2 arranged opposite to each other. The fill light emitted by the light-emitting module 1 can pass through the dimming module 2 and be emitted out. By setting a light control unit 21 in the dimming module 2 and making the light control unit 21 have a first circuit connection state and a second circuit connection state, in the first circuit connection state, the dimming module 2 and the light-emitting module 1 cooperate to emit direct light, providing a more focused and brighter light for fill light. In the second circuit connection state, the dimming module 2 and the light-emitting module 1 cooperate to emit diffused light, providing a more uniform and softer light for fill light, so as to adapt to the fill light needs in different shooting environments, provide different fill light solutions, and improve the overall image quality of the captured image.
