[0021] Here, the exemplary embodiments will be described in detail, and the examples are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0022] In the accompanying drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are some but not all of the embodiments of the present disclosure. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present disclosure, and should not be construed as a limitation to the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts fall within the scope of protection of the present disclosure. The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0023] In the description of the embodiments of the present disclosure, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "lateral", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the embodiments of the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the scope of protection of the embodiments of the present disclosure. It should be noted that: unless otherwise specifically stated, the relative arrangements, numerical expressions and values of the components set forth in these embodiments do not limit the scope of the present disclosure.

[0024] In recent years, the shooting function of mobile terminals has become one of the features that users are most concerned about, and it is also one of the most important factors in the technical competition and selling point comparison among major mobile terminal manufacturers.

[0025] Currently, with the development of the full-screen technology of mobile terminals, the camera module is being integrated towards the bottom of the display screen. However, due to the extremely low transmittance of the display screen, the illuminance of the camera module during shooting is low, which affects the shooting effect of the camera module.

[0026] To solve the above problems, currently, the method of reducing the pixel density (Pixel Per Inch, abbreviated as PPI) of the display screen is mostly adopted to increase the transmittance of the display screen. Since reducing the PPI of the display screen will seriously affect the display effect of the display screen, this will affect the user experience during the use of the mobile terminal.

[0027] To solve the above problems, currently, a camera module with a higher sensitivity sensor is also used. In this way, the influence of the display screen on the shooting effect of the camera module is reduced, but it will greatly increase the production cost of the product.

[0028] The present disclosure provides a mobile terminal. Without increasing the production cost of the product, the light-emitting module emits light outward through the light-transmitting module to supplement light for the camera module arranged under the display screen, and on the basis of realizing the full screen of the mobile terminal, the shooting effect of the camera module is guaranteed.

[0029] Figure 1 It is a schematic structural diagram of a mobile terminal according to an exemplary embodiment of the present disclosure.

[0030] As Figure 1 shown, in an exemplary embodiment of the present disclosure, the mobile terminal 100 includes a camera module 101, a light-transmitting module 102, and a light-emitting module 103. Each module and the setting of each module will be introduced separately below.

[0031] The camera module 101 is disposed under the display screen 104 of the mobile terminal 100.

[0032] Disposing the camera module 101 under the display screen 104 can achieve a full-screen of the mobile terminal 100, so as to improve the aesthetics of the mobile terminal 100 and the user's experience of enjoying a large-screen display during use.

[0033] The display screen 104 can be an OLED display screen, an IPS display screen, an SLCD display screen, etc. In the present disclosure, the material of the display screen 104 is not specifically limited.

[0034] Figure 2 It is a schematic plan view of a mobile terminal according to an exemplary embodiment of the present disclosure.

[0035] As Figure 2 shown, the light-transmitting module 102 penetrates through the dispensing area 109 formed by the front shell 105 and the cover plate 106 of the mobile terminal 100, extends to and is fixed inside the mobile terminal 100. The cover plate 106 is bonded to the upper surface of the light-transmitting module 102 through a light-transmissible optical adhesive 107.

[0036] The light-transmitting module 102 is a module that can penetrate light.

[0037] The dispensing area 109 formed by the front shell 105 and the cover plate 106 is the connection part between the front shell 105 and the cover plate 106. In the dispensing area 109, the cover plate 106 can be fixed to the front shell 105.

[0038] The dispensing area 109 formed by the front shell 105 and the cover plate 106 is what is called the "black edge of the mobile terminal screen" in the industry.

[0039] The light-transmitting module 102 penetrating through the dispensing area 109 formed by the front shell 105 and the cover plate 106 can be expressed as the light-transmitting module 102 being inserted into the black edge of the mobile terminal screen.

[0040] By bonding the cover plate 106 to the upper surface of the light-transmitting module 102, it is ensured that the cover plate 106 can be fixed to the front shell 105 of the mobile terminal 100.

[0041] In one embodiment, the cover plate 106 may be a glass cover plate. The glass cover plate may be a chemically strengthened glass cover plate. By setting the cover plate 106 of the mobile terminal 100 as a chemically strengthened glass cover plate, the strength and impact resistance of the cover plate 106 of the mobile terminal 100 can be improved on the premise of realizing the sensitive response of the touch screen panel of the mobile terminal 100, and thus the service life of the mobile terminal 100 can be extended.

[0042] The light-emitting module 103 is disposed under the light-transmitting module 102. The light-emitting module 103 can emit light outward through the light-transmitting module 102.

[0043] Since the light-transmitting module 102 is a light-transmissible material, and the cover plate 106 is bonded to the light-transmitting module 102 through a light-transmissible optically transparent adhesive 107, it can be ensured that the light-emitting module 103 can emit light outward through the light-transmitting module 102, the optically transparent adhesive 107, and the cover plate 106 in sequence.

[0044] The light emitted by the light-emitting module 103 is used for taking pictures and filling light for the camera module 101 disposed under the display screen 104, so as to ensure the shooting effect of the camera module 101.

[0045] The light-emitting module 103 may be a single light-emitting body or a light-emitting array, such as an LED lamp or an LED lamp array. In the present disclosure, no specific limitation is imposed on the light-emitting module 103.

[0046] A mobile terminal 100 provided by the present disclosure, by setting the light-transmitting module 102 and the light-emitting module 103, enabling the light-emitting module 103 to emit light outward through the light-transmitting module 102, and filling light for the camera module 101 disposed on the display screen 104, on the basis of realizing the full-screen of the mobile terminal 100, ensures the shooting effect of the camera module 101.

[0047] Figure 3 It is a schematic structural diagram of another mobile terminal according to an exemplary embodiment of the present disclosure.

[0048] As Figure 3 shown, in an exemplary embodiment of the present disclosure, the mobile terminal 100 further includes an optical ink 108.

[0049] The optical ink 108 is coated on the lower surface of the cover plate 106. Among them, the optical ink 108 has a preset transmittance.

[0050] Figure 4 It is a schematic diagram of the relationship between the light absorption wavelength and the transmittance of an optical ink.

[0051] In one embodiment, as Figure 4As shown, when the wavelength of the light passing through the optical ink 108 is between 380 nm and 780 nm, the transmittance of the optical ink 108 mainly concentrates between 30% and 50%; when the wavelength of the light passing through the optical ink 108 is between 780 nm and 850 nm, the transmittance of the optical ink 108 will be at a high level, far higher than 50%.

[0052] By coating the optical ink 108 on the lower surface of the cover plate 106, the dispensing area 109 of the mobile terminal 100 can be made to appear darker, thereby improving the aesthetics of the appearance of the mobile terminal 100.

[0053] Since the optical ink 108 has a certain transmittance, while ensuring the aesthetics of the appearance of the mobile terminal 100, it can ensure that the light-emitting module 103 can emit light outward through the light-transmitting module 102 to provide supplementary light for the camera module 101 provided on the display screen 104, and ensure the shooting effect of the camera module 101 on the basis of realizing the full-screen of the mobile terminal 100.

[0054] In an exemplary embodiment of the present disclosure, the optical ink 108 coated on the lower surface of the cover plate 106 can be at least one layer.

[0055] By setting the optical ink 108 to be at least one layer, on the premise of ensuring that the light-emitting module 103 can emit light outward through the light-transmitting module 102 to provide supplementary light for the camera module 101 provided on the display screen 104, it can further ensure that the dispensing area 109 of the mobile terminal 100 appears black, improving the aesthetics of the appearance of the mobile terminal 100.

[0056] In an exemplary embodiment of the present disclosure, the light-transmissive optical adhesive 107 can be an OCA (Optically Clear Adhesive) optical adhesive.

[0057] The OCA (Optically Clear Adhesive) optical adhesive is a type of double-sided adhesive with optical transparency.

[0058] The OCA optical adhesive has the characteristics of being colorless, transparent, and having a light transmittance exceeding 90%.

[0059] Since the OCA optical adhesive has a high light transmittance, it can ensure that during the process of the light-emitting module 103 emitting light outward through the light-transmitting module 102, the light-transmissive optical adhesive 107 and the cover plate 106 in sequence, the light will not be lost too much, and thus it can ensure that supplementary light is provided for the camera module 101 provided on the display screen 104, and ensure the shooting effect of the camera module 101 on the basis of realizing the full-screen of the mobile terminal 100.

[0060] In an exemplary embodiment of the present disclosure, the light-transmitting module 102 may be a light-transmitting support body having light-transmitting properties. On the one hand, the cover plate 106 can be fixed to the front shell 105 through the light-transmitting support body. On the other hand, based on the light-transmitting properties of the light-transmitting support body, it can be ensured that during the process of the light-emitting module 103 emitting light outward successively through the light-transmitting module 102, the light-transmissible optical glue 107, and the cover plate 106, there will be no excessive loss of light. Furthermore, it can be ensured that the camera module 101 provided on the display screen 104 is photographed and supplemented with light, and on the basis of realizing the full-screen of the mobile terminal 100, the shooting effect of the camera module 101 is ensured.

[0061] In an exemplary embodiment of the present disclosure, the light-transmitting module 102 and the front shell 105 are integrally formed by two-shot injection molding. Among them, the material of the light-transmitting module 102 is a light-transmitting material, and the material of the front shell 105 is an opaque material.

[0062] Two-shot injection molding is a production method of materials, which can mix two materials of different materials for production, so that the manufactured product can include two materials of different materials.

[0063] Setting the light-transmitting module 102 and the front shell 105 as an integral body by two-shot injection molding can reduce the installation complexity of the components of the mobile terminal 100, and thus improve the work efficiency.

[0064] Since the material of the light-transmitting module 102 is a light-transmitting material, it can be ensured that during the process of the light-emitting module 103 emitting light outward successively through the light-transmitting module 102, the light-transmissible optical glue 107, and the cover plate 106, there will be no excessive loss of light. Furthermore, it can be ensured that the camera module 101 provided on the display screen 104 is photographed and supplemented with light, and on the basis of realizing the full-screen of the mobile terminal 100, the shooting effect of the camera module 101 is ensured.

[0065] In one embodiment, the energy of the light emitted by the light-emitting module 103 can be determined according to the energy of the light that needs to be supplemented by the camera module 101 provided on the display screen 104 during the photographing process.

[0066] Since the material of the front shell 105 is set as an opaque material, it can be ensured that during the process of the light-emitting module 103 emitting light outward successively through the light-transmitting module 102, the light-transmissible optical glue 107, and the cover plate 106, it will not be affected by the light conducted in through the front shell 105, ensuring the accuracy of the energy of the light that the light-emitting module 103 needs to supplement for the camera module 101 provided on the display screen 104 during shooting.

[0067] In an exemplary embodiment of the present disclosure, the mobile terminal 100 further includes a color temperature sensor, and the light emitting module 103 may be a color temperature compensation light strip. Among them, based on the color temperature value measured by the color temperature sensor and the standard color temperature value, the color temperature value compensated by the color temperature compensation light strip is determined.

[0068] The standard color temperature value may be the color temperature value of the captured image determined by the shooting system of the mobile terminal 100 based on the current shooting environment, or may also be a manually set color temperature value.

[0069] The color temperature sensor can measure the color temperature value of the image that the current camera module 101 can capture. The difference between the color temperature value measured by the color temperature sensor and the standard color temperature value can be compensated by the color temperature compensation light strip, so as to ensure the color temperature shooting effect of the captured image.

[0070] Since the color temperature compensation light strip can also emit light, the color temperature compensation light strip can emit light outward through the light transmission module 102 to provide supplementary light for the camera module 101 disposed on the display screen 104. On the basis of realizing the full screen of the mobile terminal 100, the shooting effect of the camera module 101 is ensured.

[0071] Setting the light emitting module 103 as a color temperature compensation light strip can not only perform brightness compensation on the camera module 101 disposed on the display screen 104, but also perform color temperature compensation on the captured image, so as to ensure the overall shooting effect of the camera module 101.

[0072] In an exemplary embodiment of the present disclosure, the width of the light transmission module 102 is less than a preset width.

[0073] In order to realize the full screen of the mobile terminal 100, therefore, the black edge of the mobile terminal screen should be as small as possible. Furthermore, the width of the light transmission module 102 inserted into the black edge of the mobile terminal screen also needs to be as small as possible.

[0074] The width of the light transmission module 102 is less than the preset width, where the preset width can be adjusted according to the actual situation. For example, the preset width may be 1.0 mm. In the present disclosure, no specific limitation is imposed on the preset width.

[0075] In an exemplary embodiment of the present disclosure, the distance between the camera module 101 and the light transmission module 102 is greater than a preset distance.

[0076] If the distance between the camera module 101 and the light transmission module 102 is too small, the light emitted by the light transmission module 102 will affect the shooting effect of the camera module 101 during shooting. Therefore, the distance between the camera module 101 and the light transmission module 102 needs to be greater than the preset distance.

[0077] Among them, the preset distance can be adjusted according to the actual situation. In the present disclosure, no specific limitation is imposed on the preset distance.

[0078] In one embodiment, the imaging module 101 may be disposed at the upper end of the mobile terminal 100. The light-transmitting module 102 may pass through the dispensing area 109 formed by the front shell 105 and the cover plate 106 at the upper end of the mobile terminal 100.

[0079] In one embodiment, the imaging module 101 may be disposed at the upper end of the mobile terminal 100. The light-transmitting module 102 may pass through the dispensing area 109 formed by the front shell 105 and the cover plate 106 at the left end of the mobile terminal 100.

[0080] In one embodiment, the imaging module 101 may be disposed at the upper end of the mobile terminal 100. The light-transmitting module 102 may pass through the dispensing area 109 formed by the front shell 105 and the cover plate 106 at the right end of the mobile terminal 100.

[0081] In one embodiment, the imaging module 101 may be disposed at the upper end of the mobile terminal 100. The light-transmitting module 102 may pass through the dispensing area 109 formed by the front shell 105 and the cover plate 106 at the lower end of the mobile terminal 100.

[0082] In an exemplary embodiment of the present disclosure, the aforementioned mobile terminal 100 may be a mobile phone, a tablet computer, a smart wearable device, or other mobile terminal devices.

[0083] For purposes of illustration and description, the foregoing description of the implementation of the present disclosure has been given. The foregoing description is not exhaustive, nor is it intended to limit the present disclosure to the exact form disclosed. Various modifications and variations are possible in light of the above teachings, or various modifications and variations may be obtained from the practice of the present disclosure.
