The embodiments described below with reference to the accompanying drawings are illustrative and are only for the purpose of explaining the present application and are not to be construed as limiting the present application.
The following disclosure provides many different embodiments or examples for implementing different features of the application. In order to simplify the disclosure of the present application, specific example components and arrangements are described below. Of course, they are merely examples and are not intended to limit the present application. Moreover, the present application may repeat reference numerals and/or letters in the various examples, such repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, examples of various specific processes and materials are provided herein, but one of ordinary skill in the art may recognize applications of other processes and/or use of other materials.
Referring to fig. 1 and 2, a housing assembly 100 is provided, in which the housing assembly 100 includes a housing 11 and a surface light source 12. The housing 11 includes a first surface 110 and a second surface 111, the second surface 111 is opposite to the first surface 110, and the second surface 111 is configured to face the inside of the electronic device 1000 (shown in fig. 8); the surface light source 12 is disposed on the second surface 111, and the surface light source 12 emits light out of the first surface 110 through the housing 11.
The housing assembly 100 in the embodiment of the present application, by disposing the surface light source 12 on the second surface 111, the surface light source 12 can be disposed between the housing 11 and the electronic device 1000, so that the housing 11 can protect the surface light source 12 to a certain extent, and by disposing the surface light source 12 between the housing 11 and the electronic device 1000, the electronic device 1000 can be decorated better, and light emitted from the surface light source 12 to the outside of the first surface 110 through the housing 11 is prevented from leaking from two sides of the housing 11.
Specifically, with the progress of science and technology, various electronic products are widely used in people's lives, and in order to increase the appearance expressive force of the products to improve competitiveness, the rear cover of the electronic product can be designed with patterns and light effect changes. However, when the light emitting device is disposed to change the lighting effect of the rear cover of the electronic product, the light emitting device is not well protected, and the light emitting device itself may also bring about a certain potential safety hazard.
For example, when an Electroluminescent (EL) material is used as the surface light source 12, since the EL electroluminescent technology is generally driven by a high voltage (greater than 36V) ac power source, the high voltage ac power source needs to add a separate power chip inside the electronic device 1000, which increases the manufacturing cost, and the high voltage also poses a safety hazard to users, especially when the EL is used as a light emitting source and is generally disposed on the first surface 110 of the housing 11, the safety hazard is greatly increased, and the protection of the surface light source 12 is also not facilitated.
In order to solve the above problem, the present embodiment provides the surface light source 12 on the second surface 111 facing the inside of the electronic device 1000, so as to protect the surface light source 12 and improve the safety of the user.
Specifically, the electronic device 1000 may be an electronic product such as a smart phone, a tablet computer, a notebook computer, and an intelligent watch, and the case assembly 100 may support and protect the electronic device 1000 to some extent, and meanwhile, the case assembly 100 may generate a corresponding lighting effect by adding the light source 12 that emits light through controlling the light source 12, so as to decorate the electronic device 1000.
The shell assembly 100 includes a shell 11, the shape of the shell 11 may be a plurality of regular or irregular shapes such as a rectangle, an oblong, etc., the material of the shell 11 may include a transparent plastic plate, such as a Polycarbonate (PC) plate, a polymethyl methacrylate (PMMA) plate, etc., and may also be glass, so that the shell 11 may have a certain visible light transmittance. Further, in order to enhance the decoration effect of the shell assembly 100, patterns may be formed on the shell 11 by screen printing, spraying color ink, or attaching a decoration film on the shell 11.
The housing 11 includes a first surface 110 and a second surface 111, the second surface 111 is opposite to the first surface 110, the second surface 111 is configured to face the inside of the electronic device 1000, and correspondingly, the first surface 110 is away from the inside of the electronic device 1000.
The shell assembly 100 further includes a surface light source 12, and the surface light source 12 may be formed by coupling LED beads and a diffusion film, may be an EL material, or may be an organic light emitting material, a quantum dot material, or the like. The surface light source 12 is disposed on the second surface 111, that is, the surface light source 12 is disposed inside the electronic device 1000. Since the structure of the coupling of the LED lamp beads and the diffusion film is complex, display problems such as uneven brightness and light spots are likely to occur, and the EL material requires an additional power chip, the surface light source 12 can be preferably made of an organic light emitting material and a quantum dot material in consideration of the manufacturing cost, the light weight, the light effect display effect, and the like of the electronic device 1000.
The surface light source 12 is disposed on the second surface 111 and is disposed toward the first surface 110 so that the surface light source 12 can emit light out of the first surface 110 to light the housing 11. Particularly, the light source 12 can be further controlled, for example, the surface light source 12 is divided into a plurality of light emitting areas, and each light emitting area is independently controlled, so that the housing assembly 100 can generate rich light effects such as dynamic multi-color light emission, stacked color light emission, and the like, thereby enriching the appearance of the electronic device 1000.
In addition, since the surface light source 12 is disposed on the second surface 111, the housing assembly 100 can cover both sides of the surface light source 12, so as to prevent light emitted from the housing 11 to the outside of the first surface 110 from leaking from both sides of the housing assembly 100 when the surface light source 12 emits light, thereby achieving a better decoration effect on the electronic device 1000.
In the description of the present application, it is to be understood that the terms "inside", "outside", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features.
Referring to fig. 1 and 2, in some embodiments, the housing 11 may include a light-transmitting region 112 and a non-light-transmitting region 113, and the surface light source 12 may be disposed corresponding to the light-transmitting region 112. In this way, by disposing the surface light source 12 corresponding to the light-transmitting area 112, the light emitted from the surface light source 12 can be emitted out of the first surface 110 of the housing 11 through the light-transmitting area 112, so as to light the electronic device 1000.
Specifically, the non-light-transmitting region 113 may be a certain pattern region formed on the housing 11 by screen printing, ink spraying, or decoration film pasting for the sake of beauty of the housing 11 of the electronic device 1000, and the light-transmitting region 112 may be a corresponding non-pattern region, and the surface light source 12 is disposed corresponding to the light-transmitting region 112, so that the light-transmitting region 112 can transmit light generated by the surface light source 12, and the non-light-transmitting region 113 and the light-transmitting region 112 form a light-dark contrast to display a pattern of the non-light-transmitting region 113.
It can be understood that the transmittance of the non-light-transmitting region 113 needs to be smaller than a preset value, and the preset value can be set according to the actual display requirement, so that the light leaking from the surface light source 12 can not be transmitted out of the first surface 110 by the non-light-transmitting region 113 to affect the pattern display effect when the light leaking from the surface light source 12 corresponding to the light-transmitting region 112 is generated.
In some embodiments, the visible light transmittance of the light-transmitting region 112 may be greater than 50%. In this way, the light-transmitting area 112 can transmit the light emitted by the surface light source 12 disposed on the second surface 111 and corresponding to the light-transmitting area 112, so as to transmit the light out of the first surface 110, thereby achieving the light-emitting display effect of the housing 11.
Specifically, the main material of the housing 11 in the housing assembly 100 may be a transparent plastic plate including a Polycarbonate (PC) plate, a polymethyl methacrylate (PMMA) plate, or the like, or may be a transparent glass, which is characterized in that the visible light transmittance of the housing 11 is greater than 50%.
The housing 11 includes a non-light-transmitting region 113 formed with a certain pattern by screen printing, spraying, or attaching a decorative film, for the sake of aesthetic appearance, and the non-light-transmitting region 113 has low visible light transmittance, so that light leaking from the surface light source 12 is not transmitted to the outside of the first surface 110. Correspondingly, the light-transmitting area 112 is not provided with patterns, areas such as ink spraying areas are not provided with the patterns, the light-transmitting area 112 keeps the original transparent state of the material of the shell 11, so that the visible light transmittance of the light-transmitting area 112 can be larger than 50%, the light-transmitting area 112 can transmit light emitted by the surface light source 12 arranged on the second surface 111 and corresponding to the light-transmitting area 112, the light is transmitted out of the first surface 110, and the light-emitting display effect of the shell 11 is achieved.
Referring to fig. 1-4, in some embodiments, the surface light source 12 may be attached to the second surface 111, or the second surface 111 may be provided with a groove 1110, and the surface light source 111 may be embedded in the groove 1110.
Thus, the surface light source 12 is attached to the second surface 111, so that the second surface 111 and the surface light source 12 can be fixedly connected to protect the surface light source 12 from contaminants such as dust, water vapor and the like, and the surface light source 12 can emit uniform and stable light to light the housing 11; by embedding the surface light source 12 in the groove 1110, the structure of the housing assembly 100 is more compact, so that the internal space of the electronic device 1000 can be saved, and the space utilization of the electronic device 1000 can be increased.
Specifically, when the surface light source 12 is attached to the second surface 111, the surface light source 12 may be attached to the second surface 111 by using the optical adhesive 13, and the optical adhesive 13 needs to be made of a transparent material to provide high transmittance, so as not to affect the surface light source 12 to emit light out of the first surface 110 through the light-transmitting area 112. The optical adhesive 13 may be of various types, for example, a synthetic resin optical adhesive 13 having characteristics of high bonding strength, good high and low temperature resistance, and being capable of working under severe conditions such as vibration and radiation, and the like, and specifically, a synthetic resin transparent adhesive for an optical element includes unsaturated polyester, epoxy adhesive, polyurethane adhesive, silicone gel, photo-curing adhesive, and the like.
When the second surface 111 is provided with the groove 1110, the shape of the groove 1110 may match with the shape of the inside of the surface light source 12, and in addition, the thickness of the groove 1110 may be equal to the overall thickness of the surface light source 12, so that the surface light source 12 does not protrude from the groove 1110 but is flush with the second surface 111 of the housing 11.
In this way, by embedding the surface light source 12 in the groove 1110, a space for mounting the fixed surface light source 12 can be saved, and a space utilization rate of the electronic device 1000 can be increased, or in other words, it is not necessary to provide an additional space for mounting the surface light source 12, so that the thickness of the electronic device 1000 can be reduced.
Referring to fig. 2 and 4, in some embodiments, the surface light source 12 may include a substrate 120 and a luminescent layer 121, and the luminescent layer 121 may be disposed on the substrate 120. Thus, the substrate 120 can provide support for the light-emitting layer 121, and the substrate 120 and the light-emitting layer 121 together form the surface light source 12 with a compact structure.
Specifically, the substrate 120 may be a flexible substrate 120, for example, the substrate 120 may be polyethylene terephthalate (PET), Polycarbonate (PC), Polyimide (PI), or the like. The light emitting layer 121 serves as a light source, the number of the light emitting layers 121 can be one or more, the shape and size of the light emitting layer 121 is matched with the shape and size of the light transmitting area 112 of the shell 11, so that light emitted by the light transmitting area 112 through the light emitting layer 121 can form contrast with the non-light transmitting area 113 in light and shade, and when a pattern is formed in the non-light transmitting area 113, the pattern shape is displayed in contrast. In the case where the number of the light emitting layers 121 is plural, the light emitting layers 121 may be arranged in parallel or stacked.
In some embodiments, the material of the light emitting layer 121 may include an organic light emitting material and/or a quantum dot material. So, can make the fine and smooth even of the light that sends of luminescent layer 121 to the display effect of casing 11 is better, and because the characteristic of organic luminescent material and quantum dot material, luminescent layer 121 can be thickness thinner, and can range upon range of setting in order to provide richer light efficiency.
Specifically, in the current technology of making multiple light emitting effects on the housing 11 of the electronic device 1000, since the point light source needs to be disposed at a certain distance to uniformly scatter the light and the light diffusion plate needs to be disposed to further uniformly emit the light, the light emitting source generally adopts the surface light source 12 to reduce the thickness of the electronic device 1000.
In the conventional common surface Light source 12 structure, if a miniaturized Light-Emitting Diode (LED) lamp bead is used in combination with a diffusion sheet, the LED lamp bead and the diffusion sheet need to be coupled together, the structure is relatively complex, and the problem that the brightness is not uniform due to non-uniform Light diffusion, and even serious people have Light spots, is easily caused. And because diffusion piece optical structure is last can not cut apart, LED lamp pearl is in the same place with it coupling again, if want to realize sending display effect such as the light of different colours at different moments, its optical structure can be more complicated.
If an Electroluminescent (EL) material is used, although EL is a better flexible surface light source 12, the EL electroluminescent technology is generally driven by a high-voltage (greater than 36V) ac power source, which requires a separate power chip to be added inside the electronic device 1000, which increases the manufacturing cost, and the high voltage also causes a safety hazard to users, especially when EL is often disposed on the first surface 110 of the housing 11 as a light emitting source.
Furthermore, the EL material is generally granular, has a particle size of about 5 μm to 25 μm, and is manufactured by a screen printing process, so that the EL material brings visual granular feeling to a user in terms of luminous effect, i.e., the final display effect is rough and not fine enough. In addition, when the light-emitting layer 121 is made of an EL material, the transparency is poor, and one EL device intelligently emits light of one color, so that when there are a plurality of light-emitting layers 121, only the plurality of light-emitting layers 121 can be selected to be arranged in parallel for display effect, and thus it is difficult to achieve the light-emitting effect of mixing light of a plurality of colors by the lamination arrangement of the light-emitting layers 121. Also, even though it is possible to allow different light emitting layers 121 to emit light at different times in a parallel arrangement in a case where the light emitting layers 121 are plural to achieve a multicolor light emitting effect, the parallel arrangement limits the design of the pattern of the housing 11 and increases the lateral size of the electronic device 1000.
In particular, in the description of the present application, "a plurality" means two or more unless specifically limited otherwise. Therefore, the material of the Light Emitting layer 121 in the embodiment of the present application may include an Organic Light Emitting material, such as an Organic Light-Emitting Diode (OLED), or a Quantum Dot material, such as a Quantum Dot Light-Emitting Diode (QLED). More specifically, the organic light emitting material includes an organic fluorescent material, an organic phosphorescent material, and the like, and the quantum dot material includes cadmium selenide CdSe, a perovskite material CsPbX3, zinc phosphide InP, copper indium sulfide CuInS2, and the like. When the number of the light emitting layers 121 is plural, the material of the light emitting layer 121 may be a combination of an organic light emitting material and a quantum dot material, or may be a single one of them.
In this way, the OLED and the QLED can be fabricated on the flexible transparent substrate 120, so that the surface light source 12 formed by combining the light-emitting layer 121 and the substrate 120 has high transparency, and the thickness of the light-emitting layer 121 is very thin due to different fabrication methods, so that a plurality of light-emitting layers 121 can be stacked, and a richer light-emitting effect can be achieved without affecting the thickness of the electronic device 1000, the pattern design of the housing 11, and the like. In particular, when the material of the light emitting layer 121 is an organic light emitting material and/or a quantum dot material, the substrate 120 to which the light emitting layer 121 is added is a Polyimide (PI) material, which is well established in the industry.
It should be noted that the organic light-emitting material and the quantum dot material are driven by low-voltage dc, the voltage range is generally in the range of 5V to 10V, and the organic light-emitting material and the quantum dot material can be directly connected to the main board power supply of the electronic device 1000 without adding an additional power chip, and in this embodiment, the light-emitting layer 121 formed by the organic light-emitting material and/or the quantum dot material is disposed on the second surface 111, so as to greatly improve the use safety of users compared with the EL material disposed on the first surface 110.
Referring to fig. 4 and 5, in some embodiments, when there are a plurality of light emitting layers 121, the light emitting layers 121 may be stacked, and at least two of the light emitting layers 121 emit light with different colors.
In this way, the multiple light-emitting layers 121 are stacked without limiting the design of the pattern of the housing 11, and the colors of the light emitted by at least two light-emitting layers 121 are different, so that the light can be emitted at different times by controlling different light-emitting layers 121, and richer light-emitting effects of the housing 11 such as multi-color switching and multi-color superposition can be realized.
Specifically, as described above, in the case that there are a plurality of light emitting layers 121, since the material of the light emitting layer 121 may be OLED and/or QLED, and the light emitting layer 121 made of OLED/QLED is generally prepared by a process scheme such as evaporation/printing, the film layer is ultra-thin, and the thickness is generally between 5nm and 100nm, so that the film layer has a certain transparency, and thus, in the case that a plurality of light emitting layers 121 are stacked, the transmittance of light emitted by any one light emitting layer 121 is not affected.
And, through piling up a plurality of luminescent layers 121, and the light color that two at least luminescent layers 121 sent is different, then can carry out solitary luminous control to every luminescent layer 121, thereby can realize sending different colour light at different moments, perhaps at same moment, control two at least luminescent layers 121 that send different colour light are luminous simultaneously, display effect such as formation new colour light with the superposition of realization different light colour, thereby richen the light efficiency of casing 11, improve electron device 1000's outward appearance expressive force.
As shown in fig. 4 and 5, the surface light source 12 includes two stacked light emitting layers 121, namely a blue light emitting layer 121A and a red light emitting layer 121B in a direction from the substrate 120 to the substrate 120, wherein the light emission control of the blue light emitting layer 121A and the red light emitting layer 121B is independent and independent from each other. Then the blue light emitting layer 121A can be controlled to emit light currently, the blue light emitting layer 121A is controlled to stop emitting light at the next moment, and the red light emitting layer 121B emits light, so that a display effect of dynamic multi-color light emission can be realized; or the blue light emitting layer 121A may be controlled to keep emitting light at the next time, and the red light emitting layer 121B emits light, at this time, red light and blue light may be superimposed, and ideally, violet light may be emitted, so as to achieve the display effect of superimposed color emission.
Referring to fig. 6 and 7, in some embodiments, the light emitting layer 121 may include a plurality of light emitting regions 1210 arranged in parallel, the light emitting regions 1210 may be located on the same layer, and the light emitted from at least two light emitting regions 1210 has different colors.
Thus, the same light emitting layer 121 is divided into a plurality of light emitting regions 1210, and the colors of the light emitted from at least two light emitting regions 1210 are different, so that at least two light emitting regions 1210 emitting light with different colors can be controlled to emit light respectively, thereby realizing a multi-color light emitting display effect.
Specifically, in order to achieve dynamic multiple optical effects, the light-emitting layer 121 may include a plurality of independent small-sized light-emitting regions 1210, or a plurality of light-emitting regions 1210 may be arranged in parallel to form one light-emitting layer 121. Since the material of the light emitting layer 121 may be OLED and/or QLED, the surface light source 12 of the above kind can easily realize multi-partition light emission compared to the conventional LED lamp bead coupling diffusion film.
As shown in fig. 6 and 7, one light-emitting layer 121 may include four independent light-emitting regions 1210, which are light-emitting regions 1210a1, 1210a2, 1210A3, and 1210a4 from top to bottom, and represent that light emission or non-light emission of any one light-emitting region 1210 does not affect light emission or non-light emission of other regions, and light emitted by at least two light-emitting regions 1210 has different colors.
Assuming that the light emitted from the light-emitting region 1210a1 and the light emitted from the light-emitting region 1210A3 are different in color, the light-emitting region 1210a1 may be currently controlled to emit light, the light-emitting region 1210a1 stops emitting light at the next time, and the light-emitting region 1210A3 emits light, or the light-emitting region 1210a1 may be controlled to keep emitting light and the light-emitting region 1210A3 emits light at the next time, so that a display effect of alternately generating different colors of light may be achieved.
Referring to FIG. 4, in some embodiments, the thickness D of the light-emitting layer 121 is in the range of 5nm to 100 nm. In this way, by keeping the thickness range D of the light-emitting layer 121 in a small range, the thickness of the light-emitting layer 121 is made thin so as not to affect the transparency of the light-emitting layer 121, so that the plurality of light-emitting layers 121 can be stacked, and the influence on the thickness of the case 11 at the time of stacking is small.
Specifically, as described above, in the case that the plurality of light emitting layers 121 are provided, since the material of the light emitting layer 121 may be OLED and/or QLED, and the light emitting layer 121 made of OLED/QLED is generally prepared by an evaporation/printing process scheme, the film layer is ultra-thin, the thickness range D can be maintained between 5nm and 100nm, and thus each light emitting layer 121 has a certain transparency, and the transmittance of light emitted by any one light emitting layer 121 can be not affected in the case that the plurality of light emitting layers 121 are stacked. Meanwhile, the plurality of light emitting layers 121 are stacked in time, so that the total thickness is not too large, the influence on the thickness of the housing 11 is small, and the electronic device 1000 is light and thin.
In some embodiments, the light emitting layer 121 may have a transmittance of greater than 50%. Thus, the light emitting layers 121 have a certain passing rate, so that when the light emitting layers 121 are stacked, light emitted by any one of the light emitting layers 121 is not affected to penetrate through the next light emitting layer 121 stacked with the light emitting layer 121, and richer light effects can be realized by stacking the light emitting layers 121 emitting light of different colors.
Specifically, the thickness range D of the light emitting layer 121 made of the OLED/QLED material can be maintained between 5nm and 100nm, and thus each light emitting layer 121 has a certain transparency, for example, the transmittance of the light emitting layer 121 can be made to be more than 50%. Thus, when a plurality of light-emitting layers 121 are provided, the colors of light emitted by at least two light-emitting layers 121 are different, and thus, when the plurality of light-emitting layers 121 are stacked, light emitted by any one light-emitting layer 121 is not affected to penetrate through the next light-emitting layer 121 stacked with the light-emitting layer 121, and when the plurality of light-emitting layers 121 emitting light of different colors emit light simultaneously, a display effect of color superposition can be achieved, and a multi-color light display effect of emitting light of different colors at different times can be achieved.

In this way, independent light emission control can be performed on each light emitting layer 121, so as to achieve a more colorful light emitting effect in the housing 11.
Specifically, as described above, in the case where the light emitting layer 121 is plural, since the light emitting layer 121 is made of the OLED/QLED material in the present application, the plural light emitting layers 121 may be stacked on the substrate 120. The substrate 120 is further provided with a conductive wire 14 corresponding to each light-emitting layer 121, and the conductive wire 14 is connected to a main board power supply of the electronic device 1000 by means of an FPC connector or a spring sheet connection. Since the wires 14 corresponding to each light-emitting layer 121 are independently provided, each wire 14 can be individually energized by the motherboard control to perform individual light-emitting control for each light-emitting layer 121.
As shown in fig. 5, the surface light source 12 includes two stacked light emitting layers 121, a blue light emitting layer 121A and a red light emitting layer 121B from the direction close to the substrate 120 to the direction away from the substrate 120, wherein the wires 14A and 14B corresponding to the blue light emitting layer 121A and the red light emitting layer 121B are independently connected to the main board.
The conductive line 14A may be currently turned on to energize the blue light emitting layer 121A to make it emit blue light, the electrical connection of the conductive line 14A to the main board may be turned off at the next time to deenergize the blue light emitting layer 121A to make it stop emitting light, and the conductive line 14B may be simultaneously turned on to energize the red light emitting layer 121B to make it emit red light, so that a display effect of dynamic multicolor light emission may be achieved; or the conducting wire 14A may be kept in the on state at the next time to keep the blue light emitting layer 121A emitting light, and the conducting wire 14B is turned on to energize the red light emitting layer 121B to make it emit red light, at this time, the red light and the blue light may be superimposed, and ideally, the purple light may be emitted, so as to realize the display effect of color-stacked light emission.
Referring to fig. 6 and 7, in some embodiments, the substrate 120 may be provided with a conductive line 14 corresponding to each light-emitting region 1210, and the conductive line 14 corresponding to each light-emitting region 1210 is independently provided. In this way, each light-emitting region 1210 can be independently controlled to achieve a more colorful light-emitting effect in the housing 11.
Specifically, as described above, the same light-emitting layer 121 may include a plurality of light-emitting regions 1210 arranged in parallel, and when the substrate 120 is provided with the wires 14 corresponding to each light-emitting region 1210, it means that the same light-emitting layer 121 may correspond to a plurality of wires 14, and the plurality of wires 14 correspond to different light-emitting regions 1210, or the plurality of wires 14 are independently arranged and independently control the light-emitting regions 1210 to emit light.
As shown in fig. 6 and 7, one light emitting layer 121 may include four independent light emitting regions 1210, for example, light emitting regions 1210a1, 1210a2, 1210A3 and 1210a4 are respectively formed in light emitting layer 121 from top to bottom, each light emitting region 1210 has an independent wire 14 connected to the motherboard, for example, wire 14a1, wire 14a2, wire 14A3 and wire 14a4 correspond to light emitting region 1210a1, light emitting region 1210a2, light emitting region 1210A3 and light emitting region 1210a 4.
Assuming that the colors of the light emitted from the light-emitting region 1210a1 and the light-emitting region 1210A3 are different, the wire 14a1 may be turned on to energize the light-emitting region 1210a1 to emit light, the electrical connection between the wire 14a1 and the main board may be turned off at the next time to deenergize the light-emitting region 1210a1 to stop emitting light, and the wire 14A3 may be turned on to energize the light-emitting region 1210A3 to emit light at the same time, or the on state of the wire 14a1 may be maintained at the next time so that the light-emitting region 1210a1 keeps emitting light, and the wire 14A3 may be turned on to energize the light-emitting region 1210A3 to emit light, thereby achieving a display effect of alternately generating different lights.
It is understood that, in the case where the surface light source 12 includes a plurality of light emitting layers 121 arranged in a stacked manner and at least two light emitting regions divide the plurality of light emitting regions 1210, the effect of color-stacked light emission can be achieved in any one of the light emitting regions 1210. For example, if light-emitting region 1210a1 of light-emitting layer 121A is controlled to emit red light and light-emitting region 1210B1 of light-emitting layer 121B is controlled to emit blue light, and light-emitting region 1210a1 and light-emitting region 1210B1 correspond to the same region of the transparent region, the region of case 11 corresponding to the transparent region can exhibit a color-mixing effect of red and blue light.
