Detailed Description

As used herein, an "electronic device" (or simply "terminal") includes, but is not limited to, an apparatus that is configured to receive/transmit communication signals via a wireline connection, such as via a Public Switched Telephone Network (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection, and/or another data connection/network, and/or via a wireless interface (e.g., for a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter, and/or another communication terminal). A communication terminal arranged to communicate over a wireless interface may be referred to as a "wireless communication terminal", "wireless terminal" or "mobile terminal". Examples of mobile terminals include, but are not limited to, satellite or cellular telephones; a Personal Communications System (PCS) terminal that may combine a cellular radiotelephone with data processing, facsimile and data communications capabilities; PDAs that may include radiotelephones, pagers, internet/intranet access, Web browsers, notepads, calendars, and/or Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver. A cellular phone is an electronic device equipped with a cellular communication module.

When an electronic device (e.g., a mobile phone) is turned off, a message reminding mechanism is generally provided to remind a user that a message needs to be viewed. The inventor finds that the following screen-off message reminding modes are mainly available at present through long-term research:

firstly, the screen-off clock utilizes the self-luminous characteristic of OLED, and several independent pixel points are used for emitting light and used as message reminding, but the screen-off clock uses the screen to emit light, so that the power consumption is larger, the endurance time of the whole machine is influenced, and meanwhile, the single OLED pixel points are used for emitting light for a long time, and the risk of screen burning can be increased.

Secondly, a breathing lamp is placed under the screen cover plate, and when a message comes, the breathing lamp continuously flickers to prompt the message. However, the screen-saving clock uses the screen to emit Light, which results in larger power consumption, thereby affecting the endurance time of the whole machine, and meanwhile, the screen-saving clock uses a single Organic Light-Emitting display (OLED) pixel to emit Light for a long time, which increases the risk of screen burning; if the breathing lamp is placed under the screen cover plate, holes need to be formed in the screen cover plate, so that the screen occupation ratio of the whole machine is reduced, and the aesthetic feeling of the whole machine is affected.

Thirdly, the Light effect of the rear cover, namely, a Light-Emitting Diode (LED) lamp is used as a Light source, and then Light is guided to the rear cover of the mobile phone through the Light guide column, so that the Light effect of the rear cover of the mobile phone can play a role in prompting, and the rear cover of the mobile phone can be cool. However, due to the light weight and thin property of the mobile phone, the internal installation space is limited, but the point light source property of the LED lamp determines that a long light emitting path is required to uniformly emit light on the light emitting surface, so that the light emitting surface has a problem of non-uniform light emission. In addition, the LED lamp usually emits light with a current of about 10mA, and at least 4 LED lamps need to be equipped for uniform light emission, which results in high power consumption and seriously affects the endurance time of the mobile phone. Due to the characteristics of uneven light emitting of the light emitting surface and high power consumption, the scheme of using the LED lamp as the light source cannot emit light on the whole surface, and the light effect experience of a user is influenced. A new electronic device is therefore needed.

The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic perspective view of an electronic device 1000 according to an embodiment of the present disclosure, and fig. 2 is an exploded schematic view of the electronic device shown in fig. 1.

The embodiment of the application provides an electronic device 1000.

Specifically, taking a cell phone as an example, the electronic device 1000 may include, but is not limited to, the case assembly 100, the device body 200, and the processor 300. The device body 200 may include a display screen assembly, a main board, a battery, and the like, and the case assembly 100 is fixedly connected to the device body 200 to receive and protect the device body 200. The processor 300 is fixed on the apparatus main body 200 and electrically connected to the apparatus main body 200, for controlling the electronic apparatus 1000.

The housing assembly 100 may include a light emitting structure 10 and a housing main body 20, and the light emitting structure 10 may be disposed on the housing main body 20 and electrically connected to the device main body 200 and the processor 300. The device body 200 may be used to supply power to the light emitting structure 10, and the processor 300 may control a light emitting color, a light emitting period, a light emitting range, etc. of the light emitting structure 10, thereby making the housing body 20 cool in color and have a prompt function.

Referring to fig. 3 to 5, fig. 3 is an exploded schematic view of a light emitting structure in a housing assembly of the electronic device shown in fig. 2, fig. 4 is a cross-sectional schematic view of an electroluminescent element in the light emitting structure shown in fig. 3, and fig. 5 is a light emitting schematic diagram of the light emitting structure shown in fig. 3.

Alternatively, the light emitting structure 10 may include, but is not limited to, an electroluminescent member 11, a first functional layer 12, a transparent cover 13, and a second functional layer 14, which are sequentially stacked. Electroluminescent 11 can send out the light of one or more colours, and second functional layer 12 can reflect light, and transparent cover 13 is used for supporting and protecting electroluminescent 11 and first functional layer 12, and second functional layer 14 can make the light partly take place to refract, partly take place to reflect. The material of the transparent cover 13 may be glass, resin, silica gel, etc., and is not limited herein.

The light emitted by the electroluminescent element 11 sequentially passes through the first functional layer 12, the transparent cover plate 13 and the second functional layer 14, and the light passing through the first functional layer 12 can be reflected for multiple times between the first functional layer 12 and the second functional layer 14, so that the light can be refracted for multiple times at the position of the second functional layer 14. Specifically, the multiple reflections of the light rays have the difference of optical path length, so that the refracted light rays form a laminated pattern according to the delaster effect, and the laminated pattern is different under different angles, thereby achieving the effect of three-dimensional lamp effect.

It should be noted that the terms "first" and "second" in the present application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless explicitly specifically limited otherwise.

Specifically, the electroluminescent element 11 may be made of an Electro Luminescence (EL) material, and operates on the principle of electroluminescence, that is, an electric field is generated by applying a voltage to two electrodes, electrons excited by the electric field hit a luminescence center, and a physical phenomenon that electrons jump, change, and recombine between energy levels causes luminescence. In this embodiment, the electroluminescent device 11 is a light emitting device, which is also called an electroluminescent sheet, an EL lamp, an EL luminescent sheet, or an EL electroluminescent sheet.

In some embodiments, the electroluminescent device 11 includes two electrode layers and a light-emitting layer 112 disposed between the two electrode layers, wherein the electrode layers and the light-emitting layer 112 are stacked on the surface of the transparent cover 13.

Specifically, the electroluminescent element 11 includes a first electrode layer 111, a light emitting layer 112, a dielectric layer 113, and a second electrode layer 114, and the first electrode layer 111, the light emitting layer 112, the dielectric layer 113, and the second electrode layer 114 are sequentially formed on the surface of the transparent cover plate 13. The first electrode layer 111 (also called a front electrode layer) is a combination layer of the light emitting surface and the front electrode, and is used as one electrode of the power supply, and the main material is a transparent ITO (Indium Tin oxide) film. The phosphor layer 112 (also referred to as a phosphor layer) is formed by dispersing phosphor particles to which an inactive agent is added in an organic polymer, with zinc sulfide (ZnS) as a base material. In the case of the organic polymer, the emission color of the phosphor can be changed by the combination of the non-active agents as the effective electric field is applied to the phosphor. The dielectric layer 113 mainly functions to generate an electric field, and the fluorescent particles are excited by the electric field to emit light. The dielectric breakdown voltage is improved while forming the electrode to the phosphor charge supply source, and the electrode has a function of stably applying a high electric field to the phosphor. For this dielectric layer 113, particles of BaTiO3 are typically dispersed in an organic polymer. The BaTiO3 is a material which is favorable for luminescence and is suitable for charge and discharge because the material has a high permittivity of 2000-3000. The second electrode layer 114 (also referred to as a back electrode layer) is used as the other electrode of the power supply, and a carbon electrode mainly composed of graphite (carbon) and using a conductive paste or a silver electrode having excellent conductivity is used as the back electrode. Since the organic electrode material is used on the decorative plate side, a device in which all the second functional layers 14 are stacked by a printing process can be manufactured.

The electroluminescent element 11 has the following advantages: firstly, the LED display screen is ultrathin, flat and uniform in brightness, the thinnest can reach 0.1mm, the occupied space is small, the weight is light, the whole LED display screen emits light, and the whole picture emits light uniformly; secondly, the shape is various, the device can be bent and curved, and can be made into convex, concave, cylindrical or ellipsoidal shapes according to the requirements of products; thirdly, energy saving and environmental protection, electroluminescence is non-toxic and harmless, does not generate ultraviolet rays, has soft light, can be used on the electronic equipment 1000 at ease, and is also very energy-saving, the electroluminescence element 11 does not consume power, and only the driving module needs to consume power. The present embodiment is based on the characteristics of uniform light emission, thin thickness, planarization, high plasticity, energy saving, environmental protection, etc. of the electroluminescent element 11, the thickness of the transparent cover plate 13 is not increased basically by disposing the electroluminescent element 11 on the transparent cover plate 13, so that the thickness of the electronic device 1000 is not increased, and secondly, the light emitting effect is very uniform, which is an effect that the LED lamp cannot achieve, and can be set into various shapes without increasing additional power consumption.

In an application scenario, the electroluminescent device 11 provided in this embodiment emits light in a normal breath for one hour, with a power consumption of about 10mAH, and the screen-off clock for one hour, with a power consumption of about 30mAH, the visible electroluminescent device 11 is used as a breathing lamp, which can significantly reduce the power consumption of the electronic device 1000 compared to the screen-off clock, and effectively improve the endurance time of the electronic device 1000. In addition, the electroluminescent element 11 can emit various colors after being electrified, and compared with a white font of a screen-off clock, the electroluminescent element 11 has more obvious reminding and better effect.

In this embodiment, the electroluminescent device 11 can emit white light, blue light, green light, blue-green light, and red light when it is powered on. In order to enrich the color of the light emitted by the electroluminescent element 11 and further increase the variability of the appearance of the electroluminescent element 11, the first functional layer 12 may be colored. The color can be realized by spraying or printing ink with colors, specifically, a layer of ink with different colors can be sprayed or printed on the decorative surface, so that when the electroluminescent elements 11 are laminated on the decorative surface, more colors can be emitted.

In some applications, the electroluminescent element 11 may be disposed on the housing assembly 100 and/or the camera assembly 400, and different functions may be realized by utilizing the light emitted from the electroluminescent element 11. In an application scenario, the electroluminescent element 11 may be used to implement a message alert function, i.e. to alert a user that a message is available for viewing. The messages may include, but are not limited to, one or more of missed incoming messages, unread text messages, unread application messages (e.g., WeChat messages, QQ messages, nailed messages, microblog messages, news messages, etc.). When a message prompt is required, power can be supplied to the two electrodes of the electroluminescent element 11, so that the electroluminescent element 11 emits light. When the electroluminescent element 11 is illuminated, it is said that there is currently an unread message.

Optionally, the electroluminescent element 11 may select a corresponding breathing mode for reminding according to the message type. The on-off periods of the electroluminescent elements 11 corresponding to different breathing modes are different, so that when the number of the electroluminescent elements 11 is one, the messages can be displayed differently when the message types are different, and thus, a user can know the type of the unread message conveniently. For example, when there is a missed call message, the device will turn on and off actively according to the period of 1s after turning off the screen, and remind the user that there is a missed call to be checked; when unread short message messages exist, the equipment can be actively turned on and off according to a 2s period after the screen is turned off, and a user is prompted to have the unread short message requirements; when the unread application message exists, the device can be turned on and off actively according to the 3s period after turning off the screen, and the user is prompted to have the unread short message requirement.

In some embodiments, when the number of electroluminescent elements 11 is greater than 1, different types of information may correspond to electroluminescent elements 11 of different emission colors. For example, if the number of the electroluminescent elements 11 is 2, one electroluminescent element 11 with a red light emitting color is responsible for reminding a missed call, and the other electroluminescent element 11 with a blue light emitting color is responsible for reminding an unread message. With the increase of the number of the electroluminescent elements 11, the types of the messages can be further divided into WeChat messages, QQ messages, nailing messages and the like, so that the electroluminescent elements 11 with corresponding colors, sizes or shapes can be allocated for the types of each message, a user can quickly distinguish the types of unread messages, whether the messages are displayed on the screen or not can be selected for checking, invalid message checking is avoided, the screen brightness is reduced, the energy consumption of the electronic device 1000 can be reduced, and the user experience is improved.

In some embodiments, at least two electroluminescent elements 11 with different light emitting colors may be stacked on the surface of the first functional layer 12, so that when at least two electroluminescent elements 11 emit light simultaneously, the light emitted from different electroluminescent elements 11 may be mixed to visually present a new color, thereby enriching the light emitting colors of the housing assembly 100 and/or the camera assembly 400 and enhancing the decorative effect. In addition, at least two electroluminescent elements 11 arranged in a stack may emit light alternately at the same position. For example, after the previous electroluminescent element 11 is lighted, the next electroluminescent element 11 is lighted, after the next electroluminescent element 11 is lighted, the previous electroluminescent element 11 is lighted, and so on, thereby realizing the cross luminescence. Therefore, the luminous area can be increased while different types of message reminding are carried out by using the electroluminescent elements 11 with different luminous colors, so that the reminding effect is enhanced.

In some embodiments, at least one of the color, the on-off period, the shape, and the size of the electroluminescent element 11 for different breathing patterns are different, so that at least one of the color, the on-off period, the shape, and the size of the electroluminescent element 11 for different types of messages are different when the different types of messages correspond to different breathing patterns. For example, the different types of messages may correspond to different colors, on-off periods, shapes and sizes of the electroluminescent elements 11, so that the user can more easily distinguish the type of unread message.

Specifically, the first functional layer 12 has light transmittance, that is, at least a part of light emitted by the electroluminescent element 11 can pass through the first functional layer 12, and the light passing through the first functional layer 12 is reflected between the first functional layer 12 and the second functional layer 14 for multiple times, so that the light can be refracted for multiple times at the position of the second functional layer 14, and further, the three-dimensional lamp effect is achieved.

It will be appreciated that the first functional layer 12 has a low optical transparency or is opaque, since the first functional layer 12 is capable of reflecting light.

Alternatively, the first functional layer 12 may have weak light transmittance, and light emitted from the electroluminescent element 11 sequentially passes through the first functional layer 12, the transparent cover plate 13 and the second functional layer 14, so that the light-emitting structure 10 emits light as a whole and presents a three-dimensional effect. In this embodiment, the first functional layer 12 is made of mirror paint, so that the light can partially pass through the first functional layer 12 and can be reflected. In particular, about 5-10% of the light emitted by the electroluminescent element 11 can pass through the first functional layer 12, while the other part is absorbed by the first functional layer 12. In other embodiments, the first functional layer 12 may also be a colored ink layer, and the electroluminescent element 11 can illuminate the first functional layer 12 and superpose the color of the first functional layer 12, so that the light-emitting structure 10 can show bright and colorful colors.

Optionally, the first functional layer 12 may be opaque, and the first functional layer 12 may be opened with a hollow pattern 121, and light emitted by the electroluminescent element 11 can pass through the hollow pattern 121, so that light at a position corresponding to the hollow pattern 121 exhibits a three-dimensional effect. The hollow pattern 121 may be a logo, a flower pattern, etc., which are not specifically listed herein. In a specific embodiment, the first functional layer 12 can be a light absorbing ink layer, and on one hand, the light absorbing ink layer can be formed on the surface of the electroluminescent element 11 by spraying or coating, so that the first functional layer 12 not only has the characteristics of thin thickness and light weight, but also has a good light absorbing effect, and the light emitting structure 10 can only display the hollow pattern 121 due to the design. In other embodiments, the first functional layer 12 may also be a light shielding plate, a tin foil, or other non-light-transmitting structure, which is not listed here.

Optionally, the first functional layer 12 may have weak light transmittance, and the first functional layer 12 may be opened with a hollow pattern 121. The light emitted from the electroluminescent element 11 partially passes through the first functional layer 12 through the hollow pattern 121, and partially passes through the first functional layer 12 directly. It can be understood that the light passing through the hollow-out pattern 121 can generate a three-dimensional pattern light effect corresponding to the hollow-out pattern 121, and the light directly passing through the first functional layer 12 can generate a three-dimensional background light effect corresponding to the first functional layer 12, that is, the three-dimensional background light effect is used for supporting the three-dimensional pattern light effect, so that the light-emitting structure 10 has a light-emitting effect and is well-arranged and prominent in main body.

Further, the first functional layer 12 can also be a colored ink layer, on one hand, partial light of the electroluminescent element 11 can pass through the hollow pattern 121 to display the color emitted by the electroluminescent element 11, on the other hand, the electroluminescent element 11 can also illuminate the first functional layer 12, and through color superposition, the first functional layer 12 displays the color different from the position of the hollow pattern 121, so that the color of the light-emitting structure 10 is gorgeous and the level is distinct.

In a specific embodiment, the material of the second functional layer 14 is a semi-reflective semi-permeable paint, and the second functional layer 14 is sprayed on the transparent cover plate 13, and can be used for refracting a part of light passing through the second functional layer 14 and reflecting the other part of light. According to the difference of the proportion of the semi-reflecting and semi-permeable paint components, the second functional layer 14 can refract 5% -30% of light and reflect 70% -95% of light. In order to make the light emitting structure have a good gradation effect, it is necessary to make light reflected for multiple times and have good luminous efficiency and brightness, and the second functional layer 14 is preferably capable of refracting 10% of light and reflecting 90% of light.

Referring to fig. 5, specifically, when the light of the electroluminescent device 11 passing through the first functional layer 12 and/or the hollow pattern 121 first passes through the second functional layer 14, about 10% of the light is refracted to pass through the second functional layer 14, and about 90% of the light is reflected to the surface of the first functional layer 12. Since the material of the first functional layer 12 is the mirror finish, the first functional layer 12 reflects the light reflected by the second functional layer 14 to the second functional layer 14 again and passes through the second functional layer 14 for the second time, similarly, about 10% of the light passing through the second functional layer 14 for the second time is refracted and passes through the second functional layer 14, and 90% of the light is reflected and reflected to the surface of the first functional layer 12. The light generated through the second functional layer 14 can be generated between the first functional layer 12 and the second functional layer 14 for a plurality of times, and the cycle is repeated until most of the reflected light passes through the semi-reflective semi-transparent paint and reaches the outside. In the process, multiple reflections of light can have differences of optical path differences, and the refracted light forms a laminated pattern according to the Delsted effect, and the laminated pattern is different under different angles, so that the effect of three-dimensional lamp effect is achieved.

According to the light-emitting structure 10 provided by the application, the electroluminescent part 11 is arranged on the surface of the transparent cover plate 13, and the electroluminescent part 11 is ultrathin and flat, so that the installation space can be saved, and the light can be emitted uniformly; moreover, the power consumption of the electroluminescent element 11 is low, so that the use scenes of the light-emitting structure 10, such as appearance effect, unread message reminding, audio and video playing, camera shooting, incoming call reminding and the like, can be enriched, and the user experience can be improved; in addition, the arrangement of the first functional layer 12 and the second functional layer 14 enables light rays emitted by the electroluminescent element 11 to be reflected for multiple times between the first functional layer 12 and the second functional layer 14, and the multiple reflections of the light rays have differences in optical path length, so that a three-dimensional light effect is achieved.

Referring to fig. 6 to 8, fig. 6 is a schematic structural diagram of a housing assembly in another embodiment of the electronic device shown in fig. 2; FIG. 7 is a perspective view of a variation of the housing assembly shown in FIG. 6; fig. 8 is a perspective view of yet another variation of the housing assembly shown in fig. 7.

The case body 20 may include a bottom plate 21 and a rim 22. The light emitting structure 10 may be disposed on the bottom plate 21 and/or the frame 22 to make the bottom plate 21 and/or the frame 22 emit light. In this embodiment, the frame 22 may be integrally formed with the bottom plate 21, and the frame 22 and the bottom plate 21 may form an accommodating cavity to accommodate the fixing device body 200. By the design, the connection and fixation among parts can be reduced, so that the waterproof performance of the electronic equipment 1000 is improved, and the appearance consistency of the electronic equipment 1000 is good. In other embodiments, the frame 22 may be disposed separately from the bottom plate 21, and is not limited herein.
