[0002] With the popularization of smart electronic mobile devices, mobile devices (mobile phones, tablet computers and other digital devices) are becoming more and more powerful and intelligent. Charging has become a problem that users are worried about. Many users forget to charge their devices. For example, for office users, users usually plug the data cable in the charger into the PC or charger on the table, and put the mobile phone on the desk or in the pocket. When the battery of the mobile phone is low, the user cannot sense the battery level of the device.

[0003] The function of traditional mobile phones is only to charge the phone when the phone is low on power or out of power. It is impossible to remind the user of the power status of the phone when the phone is out of power, and to sense the power status of the device at any time to charge the phone. When charging, you need to unlock the phone and enter the main interface of the phone to see whether the phone is charging normally, which is troublesome to use. Many people usually set their phones to silent mode when they are at work or studying in the library. When the phone calls or receives messages, users usually cannot notice it, so they miss some important calls or messages, which brings unnecessary losses to people. However, if the phone is set to ring mode, it will affect other people's normal work, which is very inconvenient.

[0004] Therefore, existing electronic mobile devices have a lighting effect structure on the battery back cover to achieve a prompt function through the change of light, and the lighting effect can also be turned on when playing music to enhance the viewing experience and the sense of atmosphere.

Preferably, the first substrate 51 and the second substrate 52 are both made of flexible transparent materials such as acrylic acid and polycarbonate, so that the liquid crystal panel can be bent.

[0076] Furthermore, the liquid crystal panel has at least two dimming zones P, each dimming zone P corresponds to at least one control electrode 521, any two adjacent control electrodes 521 are insulated and spaced apart from each other, and each light guide plate 40 corresponds to at least one dimming zone P. Thus, the brightness of light transmitted through each dimming zone P can be individually controlled by the corresponding control electrode 521.

[0077] like Figure 6 and Figure 7 As shown, in this embodiment, each light guide plate 40 corresponds to a dimming zone P, and each dimming zone P corresponds to a control electrode 521. The dimming zone P and the control electrode 521 are both long strip structures and extend along the length direction of the light guide plate 40; the common electrode 511 is a planar electrode that covers the entire surface of the first substrate 51 and is used to apply a common signal (Vcom).

[0078] Furthermore, there are three light guide plates 40, namely, a first light guide plate 41, a second light guide plate 42, and a third light guide plate 43. The liquid crystal panel has three dimming zones P, namely, a first dimming zone P1, a second dimming zone P2, and a third dimming zone P3. The first dimming zone P1 corresponds to the first light guide plate 41 and is used to control the brightness of the light emitted by the light source 60 into the first light guide plate 41; the second dimming zone P2 corresponds to the second light guide plate 42 and is used to control the brightness of the light emitted by the light source 60 into the second light guide plate 42; the third dimming zone P3 corresponds to the third light guide plate 43 and is used to control the brightness of the light emitted by the light source 60 into the third light guide plate 43. Thus, at least two light guide plates 40 can share one light source 60.

[0079] In this embodiment, the liquid crystal layer 53 includes polymer liquid crystal molecules, which include polymer dispersed liquid crystal molecules, polymer network liquid crystal molecules or polymer stable cholesteric liquid crystal molecules, and the polymer liquid crystal molecules can switch between a transparent state and a foggy state. The common electrode 511 is disposed on the first substrate 51, so that an electric field perpendicular to the first substrate 51 and the second substrate 52 can be formed between the control electrode 521 and the common electrode 511 to drive the polymer liquid crystal molecules to switch between a transparent state and a foggy state.

[0080] like Figure 5As shown, in this embodiment, the polymer liquid crystal molecules use polymer dispersed liquid crystal molecules (PDLC). The optical axis of the small droplets composed of polymer dispersed liquid crystal molecules is in a free orientation, and its refractive index does not match the refractive index of the matrix. When light passes through the matrix, it is strongly scattered by the liquid crystal droplets and presents an opaque milky state or a translucent state. Applying an electric field can adjust the optical axis orientation of the liquid crystal droplets. When the refractive indexes of the two match, it presents a transparent state. Removing the electric field, the liquid crystal droplets return to the initial scattered light state, thereby displaying. Of course, in another embodiment, the polymer liquid crystal molecules can also use polymer network liquid crystal molecules (PNLC). The polymer network liquid crystal molecules mix low molecular liquid crystals with prepolymers. Under certain conditions, the liquid crystal molecules are included in the network through polymerization reaction. Due to orientation induction, the liquid crystal will be uniformly arranged, and the polymer monomers also have a liquid crystal phase. Under the guest-host effect, they are also uniformly arranged. At this time, the polymerization phase is separated to obtain a polymer network liquid crystal with consistent arrangement. The polymer network liquid crystal is in a transparent state when there is no voltage. When the power is on, the negative liquid crystal tends to be arranged in parallel due to the electric field. At this time, the anchoring effect of the polymer network on the liquid crystal molecules will prevent the rotation, and the liquid crystal arrangement will be disordered, which will scatter and produce a foggy state. Alternatively, in another embodiment, the polymer liquid crystal molecules can also use polymer-stabilized cholesteric liquid crystal molecules (PSCT). The cholesteric phase of the polymer-stabilized cholesteric liquid crystal molecules is in the P state when the power is removed, that is, the transparent state: when the power is on, under the action of the voltage, the cholesteric phase changes to the FC state, that is, the foggy state, and scattering occurs.

[0081] In this embodiment, the light guide plate 40, the dimming structure 50 and the light source 60 are all annular structures, so that a large area of ​​lighting effects can be achieved, and different lighting effect shapes can be achieved by combining pattern shapes. The light guide plate 40 is provided with a reflective structure 44 on the side of the non-light output / input surface. For example, a reflective or refracting coating / texture is added to the back of the light guide plate 40. By adjusting the effect of the coating / texture, the lighting effect is optimized. The light guide plate 40 is chamfered around the light guide plate to increase the total reflection effect.

[0082] Furthermore, the longitudinal sections of the first light guide plate 41, the second light guide plate 42 and the third light guide plate 43 are all L-shaped structures, so as to facilitate coordination with the dimming structure 50 and the light source 60, so that the dimming structure 50 and the light source 60 are arranged horizontally below the back cover 30 to reduce the thickness of the mobile terminal.

[0083] In this embodiment, the light source 60 is composed of multiple side-emitting RGB lamps or mini LED lamps, each of which can be individually controlled by software and hardware to achieve control of different brightness and different colors. Combined with different lighting effects, different color conversions can be achieved, thereby interacting with the APP and consumers.

[0084] Figure 8 FIG. 1 is a schematic structural diagram of the dimming structure during dimming according to the first embodiment. Fig. 9 FIG. 1 is a schematic diagram of a planar structure of a dimming structure according to the first embodiment when dimming. Figure 8 and Fig. 9 As shown, when the dimming structure 50 needs to control the brightness of the light emitted by the light source 60 into the corresponding light guide plate 40 to be weak, the voltage difference between the common electrode 511 and the corresponding control electrode 521 is controlled to be less than a first preset value, so that the polymer dispersed liquid crystal molecules are in a foggy state, thereby reducing the brightness of the light passing through the liquid crystal panel, for example Figure 8 and Fig. 9 The second dimming area P2 and the second light guide plate 42 in the dimming structure 50 are connected to the second dimming area P2 and the second light guide plate 42. When the dimming structure 50 needs to control the brightness of the light emitted by the light source 60 into the corresponding light guide plate 40 to be weak, the voltage difference between the common electrode 511 and the corresponding control electrode 521 is controlled to be greater than the second preset value, so that the polymer dispersed liquid crystal molecules are in a transparent state, thereby increasing the brightness of the light passing through the liquid crystal panel, for example Figure 8 and Fig. 9 The first dimming area P1, the first light guide plate 41, the third dimming area P3 and the third light guide plate 43 in the embodiment of the present invention are shown in FIG. 4. Therefore, by controlling the electrical signals applied to the common electrode 511 and the control electrode 521, the polymer dispersed liquid crystal molecules are controlled to switch between the mist state and the transparent state. The smaller the voltage difference between the common electrode 511 and the control electrode 521, the closer the polymer dispersed liquid crystal molecules are to the mist state. Conversely, the larger the voltage difference between the common electrode 511 and the control electrode 521, the closer the polymer dispersed liquid crystal molecules are to the transparent state. That is, the brightness of the light emitted by the light source 60 into each light guide plate 40 can be controlled by the dimming structure 50.

[0085] Second embodiment Fig.10 is a schematic diagram of a planar structure of a dimming structure according to the second embodiment. Fig.11 FIG. 1 is a schematic diagram of a planar structure of a control electrode according to the second embodiment. Fig.10 and Fig.11 As shown, the lighting effect structure provided by the second embodiment of the present invention is the same as that provided by the first embodiment ( Figures 3 to 9 ) are basically the same, except that, in this embodiment: At least two dimming sub-pixels SP are provided in each dimming zone P, and each dimming sub-pixel SP is provided with a corresponding control electrode 521, so that the brightness of different areas of each dimming zone P can be adjusted separately, that is, each dimming zone P can adjust the brightness of light transmission in different areas to achieve better lighting effects. Optionally, the dimming sub-pixels SP in each dimming zone P are arranged along the length direction of the dimming zone P, that is, arranged along the circumference of the annular dimming structure 50.

[0086] Of course, in another embodiment, each dimming zone P is provided with dimming sub-pixels SP distributed in an array, for example, each dimming zone P has three rows and ten columns of dimming sub-pixels SP, so that the dimming effect of the scoring area is better. Fig.19 , the second substrate 52 is provided with a plurality of scan lines 501, a plurality of data lines 502 and a plurality of thin film transistors 503, the plurality of scan lines 501 and the plurality of data lines 502 are mutually insulated and cross-defined to form a plurality of dimming sub-pixels SP, each dimming sub-pixel SP is provided with a thin film transistor 503, and the control electrode 521 is electrically connected to the scan line 501 and the data line 502 adjacent to the thin film transistor 503 through the thin film transistor 503. Among them, the thin film transistor 503 includes a gate, an active layer, a drain and a source, the gate and the scan line 501 are located in the same layer and are electrically connected, the gate and the active layer are separated by an insulating layer, the source is electrically connected to the data line 502, and the drain is electrically connected to the control electrode 521 through a contact hole. That is, the second substrate 52 adopts an array substrate. Since the dimming sub-pixels SP are distributed in an array, a large number of control electrodes 521 are required. If the second substrate 52 adopts an array substrate, the wiring difficulty can be reduced.

[0087] It should be understood by those skilled in the art that the rest of the structure and working principle of this embodiment are the same as those of the first embodiment and will not be described in detail here.

In the initial state, the positive liquid crystal molecules in the liquid crystal layer 53 are aligned parallel to the first substrate 51 and the second substrate 52, and the alignment directions of the positive liquid crystal molecules close to the first substrate 51 and the positive liquid crystal molecules close to the second substrate 52 are antiparallel. Of course, in other embodiments, the liquid crystal layer 53 may also use negative liquid crystal molecules, and the positive liquid crystal molecules in the liquid crystal layer 53 are aligned perpendicular to the first substrate 51 and the second substrate 52 to realize the VA display mode; or, the alignment directions of the positive liquid crystal molecules close to the first substrate 51 and the positive liquid crystal molecules close to the second substrate 52 are perpendicular to each other, that is, the positive liquid crystal molecules in the liquid crystal layer 53 are twisted 90° from the first substrate 51 to the second substrate 52 to realize the TN display mode.

[0089] In this embodiment, a common electrode 511 is further provided on the side of the second substrate 52 facing the liquid crystal layer 53. The common electrode 511 and the control electrode 521 are located in different layers and are insulated and isolated by an insulating layer. The common electrode 511 can be located above or below the control electrode 521 ( Fig.12 As shown in the figure, the common electrode 511 is located below the control electrode 521). Preferably, the common electrode 511 is a planar electrode arranged on the entire surface, and the control electrode 521 is a slit electrode having a plurality of electrode strips in each pixel unit to form a fringe field switching mode (Fringe Field Switching, FFS). Of course, in other embodiments, the control electrode 521 and the common electrode 511 are located on the same layer, but the two are insulated and isolated from each other.

[0090] Furthermore, a first polarizer 512 is disposed on a side of the first substrate 51 away from the liquid crystal layer 53, and a second polarizer 522 is disposed on a side of the second substrate 52 away from the liquid crystal layer 53. The light transmission axis of the first polarizer 512 and the light transmission axis of the second polarizer 522 are perpendicular to each other. For example, the light transmission axis of the first polarizer 51 is 0°, and the light transmission axis of the second polarizer 52 is 90°.

[0091] As shown in 13, when it is necessary to control the intensity of light passing through the liquid crystal panel, a common signal is applied to the common electrode 511, and a grayscale signal of 0-255 is applied to the control electrode 521, so that an electric field is formed between the common electrode 511 and the control electrode 521 to control the deflection of the positive liquid crystal molecules in the liquid crystal layer 53, thereby controlling the intensity of light passing through the liquid crystal panel.

[0092] It should be understood by those skilled in the art that the rest of the structure and working principle of this embodiment are the same as those of Embodiment 1 and Embodiment 2, and will not be described in detail here.

The shape of the control electrode 521 corresponds to the dimming sub-pixel SP, and also extends along the length direction of the dimming zone P.

[0095] Optionally, a color resist layer 514 corresponding to the dimming area P is provided on the first substrate 51, that is, the first substrate 51 adopts a color filter substrate, so that the light source 60 only needs to adopt a white light source, and a color effect can also be achieved, and the light color of each dimming sub-pixel SP can be adjusted according to the transmittance of the red sub-pixel, the green sub-pixel and the blue sub-pixel.

Fig.18 and Fig.19 As shown, the lighting effect structure provided by the fifth embodiment of the present invention is different from that provided by the fourth embodiment ( Figures 14 to 17 ) are basically the same, except that, in this embodiment: like Fig.18 As shown, each dimming zone P is provided with at least two red sub-pixels, at least two green sub-pixels and at least two blue sub-pixels, and the at least two red sub-pixels, at least two green sub-pixels and at least two blue sub-pixels are arranged in an array. Thus, the brightness and color of different areas of each dimming zone P can be adjusted separately, that is, each dimming zone P can adjust the brightness and color of light transmission in different areas to achieve better lighting effects.

[0098] like Fig.19As shown, the second substrate 52 is provided with a plurality of scan lines 501, a plurality of data lines 502 and a plurality of thin film transistors 503.

If the second substrate 52 adopts an array substrate, the wiring difficulty can be reduced.

[0099] It should be understood by those skilled in the art that the rest of the structure and working principle of this embodiment are the same as those of the fourth embodiment and will not be described in detail here.

Fig. 20 and Fig.21 As shown, a lighting effect structure provided in Embodiment 6 of the present invention includes at least two light guide plates 40, a dimming structure 50 and a light source 60, so that the dimming structure 50 is arranged at one end of the light guide plate 40, and the light source 60 is arranged on the side of the dimming structure 50 away from the light guide plate 40, and the dimming structure 50 is used to control the brightness of light emitted by the light source 60 into each light guide plate 40, that is, the brightness of light emitted by the light source 60 into each light guide plate 40 can be adjusted by the dimming structure 50.

[0101] In this embodiment, the dimming structure 50 includes an electrically controlled light-through valve. Optionally, the electrically controlled light-through valve includes a valve body 54, at least two light-blocking plates 55, and a driving mechanism (not shown). The valve body 54 is provided with at least two light-through holes 541, and each light-through hole 541 is provided with a corresponding light-blocking plate 55. The light-blocking plate 55 is movably connected to the valve body 54. The driving mechanism is used to drive the light-blocking plate 55 to move on the valve body 54 and block or open the light-through hole 541. Each light guide plate 40 corresponds to at least one light-through hole 541. The electrically controlled light-through valve includes a rotating shaft 56. The light-blocking plate 55 is connected to the rotating shaft 56 and is rotatably connected to the valve body 54 through the rotating shaft 56. The rotating shaft 56 is driven to rotate by the driving mechanism to drive the light-blocking plate 55 to rotate in the light-through hole 541, thereby controlling the opening amount of the light-through hole 541 to control the intensity of light passing through the electrically controlled light-through valve. Of course, in other embodiments, the light blocking plate 55 may also be slidably connected to the valve body 54, and the light blocking plate 55 may be driven to slide in the light hole 541 by a driving mechanism, thereby controlling the opening amount of the light hole 541 to control the intensity of light passing through the electrically controlled light valve.

[0102] In this embodiment, each light guide plate 40 corresponds to a light through hole 541 , and each light through hole 541 corresponds to a light blocking plate 55 . Both the light through hole 541 and the light blocking plate 55 are long strip structures and extend along the length direction of the light guide plate 40 .

[0103] Further, there are three light guide plates 40, namely, a first light guide plate 41, a second light guide plate 42, and a third light guide plate 43. There are three light holes 541, namely, a first light hole 541a, a second light hole 541b, and a third light hole 541c. There are three light baffles 55, namely, a first light baffle 551, a second light baffle 552, and a third light baffle 553. The first light baffle 551 corresponds to the first light hole 541a, and is used to control the brightness of the light emitted by the light source 60 into the first light guide plate 41; the second light baffle 552 corresponds to the second light hole 541b, and is used to control the brightness of the light emitted by the light source 60 into the second light guide plate 42; the third light baffle 553 corresponds to the third light hole 541c, and is used to control the brightness of the light emitted by the light source 60 into the third light guide plate 43. Thus, at least two light guide plates 40 can share one light source 60.

[0104] In this embodiment, the light guide plate 40, the dimming structure 50 and the light source 60 are all annular structures, so that a large area lighting effect can be achieved. The light guide plate 40 is provided with a reflective structure 44 on the side that is not the light output / input surface. For example, a reflective or refracting coating / texture is added to the back of the light guide plate 40. By adjusting the effect of the coating / texture, the lighting effect is optimized. The light guide plate 40 is chamfered around the light guide plate to increase the total reflection effect.

[0105] In this embodiment, the light source 60 is composed of a plurality of side-emitting RGB lamps or mini LED lamps, each of which can be individually controlled by software and hardware to achieve control of different brightness and different colors.

[0106] It should be understood by those skilled in the art that the rest of the structure and working principle of this embodiment are the same as those of the first embodiment and will not be described in detail here.

[0107] Seventh embodiment Fig. 22 FIG. 2 is a schematic diagram of the cross-sectional structure of the rear cover according to the seventh embodiment. Fig. 22 As shown, the lighting effect structure provided in the seventh embodiment of the present invention is basically the same as the lighting effect structure in the first to sixth embodiments, except that, in this embodiment: The lighting effect structure also includes a light guide 70, which is arranged between the dimming structure 50 and the light source 60, and is used to guide the light emitted by the light source 60 to the dimming structure 50, so that at least two light guide plates 40 can be a straight strip structure, the dimming structure 50 is set in a horizontal direction, and at least two light guide plates 40 share a light guide 70, which reduces the thickness of the light guide plate 40 and the light source 60, so as to further reduce the thickness of the mobile terminal and make it lighter and thinner.

[0108] Furthermore, the light guide plate 40 and the light guide member 70 are provided with a reflective structure 44 on the side surface other than the light exit / entry surface. For example, a reflective or refracting coating / texture is added to the back surface of the light guide plate 40 and the light guide member 70, and the lighting effect is optimized by adjusting the effect of the coating / texture. The light guide plate 40 and the light guide member 70 are chamfered around the light guide plate to increase the total reflection effect.

[0109] In this embodiment, the light source 60 is composed of multiple side-emitting RGB lamps or mini LED lamps, each of which can be individually controlled by software and hardware to achieve control of different brightness and different colors. Combined with different lighting effects, different color conversions can be achieved, thereby interacting with the APP and consumers.
