[0002] Currently, the demand for using intelligent terminals such as mobile phones and tablets to capture images and videos is increasing continuously. To improve the user's shooting experience, the display screens of intelligent terminals are getting larger and the camera functions are getting more powerful.

[0003] In some intelligent terminals, during shooting, affected by external light, flickering stroboscopic stripes will appear in the captured image, presenting a water wave shape, which affects the shooting effect. To solve the stroboscopic interference caused by shooting external light, an optical sensor is required, such as a flicker sensor. During the conception and implementation of this application, it is found that in some intelligent terminals, there are at least the following problems: The anti-flicker sensor is usually installed in a non-display area, and it is technically difficult to install the anti-flicker sensor in the display area, which is likely to affect the normal operation of the anti-flicker sensor.

For example, without departing from the scope of this document, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information.

[0061] In the related art, an optical sensor, such as an anti-flicker sensor, can be used to solve the problem of stroboscopic interference in taking pictures. The installation of the anti-flicker sensor needs to avoid the screen. Usually, a hole is opened on the housing and the light is guided by a transparent lamp cover. However, due to the blocking effect of the screen, the installation position of the anti-flicker sensor cannot be placed in the screen area, which is likely to affect the realization of the function of the anti-flicker sensor.

[0062] In addition, if the ranging module is installed under the screen, the anti-flicker sensor and the ranging module are separated from each other, occupying a large space and having a high cost.

[0063] In view of this, an intelligent terminal provided by the present application can effectively shorten the distance between the optical sensor and the ambient light source by providing a mounting hole in the display screen and arranging the optical sensor facing the mounting hole, reduce the blocking effect of the display screen on the light of the ambient light source entering the optical sensor, enable the optical sensor to realize the function of detecting the frequency of the ambient light source, and will not affect the normal operation of the optical sensor. Thus, the exposure time of the camera can be adjusted to an integer multiple of the energy cycle, achieving the effect of eliminating stroboscopic interference.

[0064] The following describes an intelligent terminal provided by an embodiment of the present application with reference to the accompanying drawings.

[0065] Refer to Figure 1 and Figure 2 As shown, the present utility model provides an intelligent terminal, including: a camera 10, refer to Figure 1 、 Figure 3 and Figure 4 As shown, the intelligent terminal further includes: a display screen 20, a control board 30, and an optical accessory 40. The display screen 20 is used to display image information. A mounting hole 24 is provided in the display screen 20, and the position of the mounting hole 24 is close to the camera 10; the control board 30 is located on the back side of the display screen 20; the optical accessory 40 includes an optical sensor 41, and the optical sensor 41 is arranged facing the mounting hole 24.

[0066] The optical sensor 41 is electrically connected to the control board 30. The optical sensor 41 is configured to detect the frequency of the ambient light source and send the detected frequency signal to the control board 30, so that the control board 30 adjusts the shooting parameters of the camera 10 according to the frequency signal.

[0067] For the intelligent terminal provided by the present utility model, by providing a mounting hole 24 in the display screen 20 and arranging the optical sensor 41 facing the mounting hole 24, the distance between the optical sensor 41 and the ambient light source can be effectively shortened, the blocking effect of the display screen 20 on the light of the ambient light source entering the optical sensor 41 is reduced, enabling the optical sensor 41 to realize the function of detecting the frequency of the ambient light source. Installing the optical sensor 41 in the display screen area will not affect the normal operation of the optical sensor 41. Thus, the exposure time of the camera 10 can be adjusted to an integer multiple of the energy cycle, achieving the effect of eliminating stroboscopic interference.

[0068] The present utility model provides an intelligent terminal. By providing a mounting hole 24 in the display screen 20, the installation of the optical accessory 40 in the screen area is realized, so that the installation of the optical accessory 40 is no longer limited to the non-screen area of the intelligent terminal. Therefore, the screen-to-body ratio of the intelligent terminal can be increased, and there is no need to reserve a non-screen area for installing the optical accessory 40 on the intelligent terminal.

[0069] The position of the mounting hole 24 is close to the camera 10, that is, the mounting hole 24 is located in the area around the camera 10. For example, the mounting hole 24 is located 5mm, 8mm, 10mm, 15mm or 20mm away from the camera 10, etc., so that the optical accessory 40 can cooperate with the camera 10 to work.

[0070] In a possible implementation manner, the shooting parameter of the camera 10 is, for example, the exposure time of the camera 10. Both the camera 10 and the optical sensor 41 are electrically connected to the control board 30. The control board 30 calculates the energy period corresponding to the ambient light source based on the detected ambient light source frequency of the optical sensor 41, and adjusts the exposure time of the camera 10 to an integer multiple of the energy period, so as to eliminate the stroboscopic stripes generated by shooting.

[0071] In a possible implementation manner, the control board 30 is a printed circuit board.

[0072] In a possible implementation manner, refer to Figure 1 and Figure 2 As shown, the camera 10 can adopt an existing camera. The number of cameras 10 can be 1, 2, 3, 4 or more. The positions of the cameras 10 can be arranged arbitrarily. For example, they can be arranged in a row horizontally, or in a column vertically, or in two columns. The camera 10 can be located on the back side of the display screen 20.

[0073] In a possible implementation manner, the optical sensor 41 includes an anti-flicker sensor (flicker sensor), which supports proximity detection, ambient light intensity detection, and ambient light stroboscopic detection.

[0074] In a possible implementation manner, the display screen 20 includes a cover plate layer 21, an optical adhesive layer 22, and a display layer 23 that are sequentially stacked. The control board 30 faces the display layer 23.

[0075] In a possible implementation manner, refer to Figure 3 and Figure 5 As shown, the mounting hole 24 is a blind hole. The mounting hole 24 penetrates through the display layer 23 and the optical adhesive layer 22. The area of the cover plate layer 21 corresponding to the mounting hole 24 is transparent. Light can enter the mounting hole 24 through the cover plate layer 21, ensuring that the intensity of the light entering the mounting hole 24 will not be greatly attenuated due to the blockage of the cover plate layer 21.

[0076] In this example, the mounting holes 24 opened in the display layer 23 and the optical adhesive layer 22 play a role in avoiding the optical sensor 41, so that the light in the environment can reach the optical sensor 41 through the cover plate layer 21 and the mounting holes 24.

[0077] In a possible implementation manner, refer to Figure 3 andFigure 4 As shown, the mounting hole 24 is a through hole that penetrates through the cover plate layer 21, the optical adhesive layer 22, and the display layer 23. In this example, the light in the environment can directly reach the optical sensor 41 through the mounting hole 24, eliminating the blocking effect of the display screen 20 on the light and ensuring the normal operation of the optical sensor 41.

[0078] In a possible implementation manner, the mounting hole 24 can be waist-shaped, or can also be oval, circular, rectangular, etc.

[0079] In a possible implementation manner, the optical accessory 40 further includes a ranging module 42, and the ranging module 42 is disposed corresponding to the mounting hole 24.

[0080] In a possible implementation manner, the ranging module 42 includes a ranging sensor, including but not limited to an infrared light ranging sensor or a laser ranging sensor.

[0081] In a possible implementation manner, the optical accessory 40 further includes a flash 43, and the flash 43 is disposed corresponding to the mounting hole 24.

[0082] In a possible implementation manner, the optical sensor 41, the ranging module 42, and the flash 43 are spaced apart and disposed on one side of the control board 30 facing the display screen 20. Such a structure facilitates the electrical connection between the flash 43 and the control board 30. When the smart terminal uses the camera 10 to take pictures, it is convenient for the control board 30 to control the flash 43 to turn on and off.

[0083] In a possible implementation manner, the smart terminal further includes an optical lamp shade 50. The optical lamp shade 50 extends into the mounting hole 24 and is located between the display screen 20 and the optical accessory 40. The optical lamp shade 50 needs to meet the light transmission requirements of the optical accessory 40, and the light received or emitted by the optical accessory 40 is corrected through the optical lamp shade 50.

[0084] In a possible implementation manner, the setting positions of the optical sensor 41, the ranging module 42, and the flash 43 on the control board 30 are all located within the projection area of the optical lamp shade 50 on the control board 30, ensuring that the light needs to pass through the optical lamp shade 50 to enter the optical sensor 41 and the ranging module 42, and the light needs to pass through the optical lamp shade 50 to emit from the flash 43.

[0085] In a possible implementation manner, any two of the optical sensor 41, the ranging module 42, and the flash 43 are separated by a barrier 60. The barrier 60 can play a role in preventing light from passing through, avoiding mutual influence when the optical sensor 41, the ranging module 42, and the flash 43 are working.

[0086] In a possible implementation manner, the ranging module 42 can be arranged between the optical sensor 41 and the flash 43. Of course, the optical sensor 41 can also be arranged between the ranging module 42 and the flash 43, or the flash 43 is arranged between the optical sensor 41 and the ranging module 42. Any two of the optical sensor 41, the ranging module 42, and the flash 43 are separated by a barrier 60.

[0087] In a possible implementation manner, the optical sensor 41 and the ranging module 42 can be fixed to the side of the control board 30 facing the display screen 20 by means such as welding, etc., to improve the stability of the fixation.

[0088] In a possible implementation manner, the size of the mounting hole 24 is adapted to the size of the optical lamp cover 50. When the optical lamp cover 50 is installed in the mounting hole 24, the optical lamp cover 50 is exactly embedded in the mounting hole 24, reducing or preventing light from entering the optical fitting 40 through the gap between the optical lamp cover 50 and the mounting hole 24.

[0089] In a possible implementation manner, the optical lamp cover 50 includes a lamp cover body 51 connected to each other and a flange portion 52 connected to the edge of the lamp cover body 51. The lamp cover body 51 extends into the mounting hole 24, and the flange portion 52 is connected to the back side of the display screen 20. A stepped surface is formed between the flange portion 52 and the lamp cover body 51. The flange portion 52 plays a role in positioning and fixing the optical lamp cover 50, thereby helping to control the depth of the optical lamp cover 50 extending into the mounting hole 24.

[0090] In a possible implementation manner, the lamp cover body 51 can be in a sheet shape. The lamp cover body 51 can be made of a transparent resin material or a transparent plastic material and has light transmissivity.

[0091] In a possible implementation manner, the flange portion 52 can be adhered to the back side of the display screen 20 by an adhesive member 54. The adhesive member 54 can be, for example, glue or double-sided tape, etc. Of course, the flange portion 52 can also be connected to the back side of the display screen 20 by other means, such as welding.

[0092] In a possible implementation manner, the optical lamp cover 50 has a first surface 512 facing away from the control board 30, and the first surface 512 is flush with the side of the cover plate layer 21 facing away from the optical adhesive layer 22, making the surface of the smart terminal flat and improving the aesthetics.

[0093] In a possible implementation manner, refer to Figure 5 and Figure 6 As shown, the lamp cover body 51 includes a light-transmitting area corresponding to the optical fitting 40, and an optical texture 55 is provided in the light-transmitting area.

[0094] The optical lamp shade 50 also has a second surface 513 facing the control board 30. The optical texture 55 can be provided on the second surface 513 of the control board 30 to make the appearance surface of the control board 30 smooth and prevent dust from falling in.

[0095] The optical texture 55 can be a toothed groove machined on the second surface 513, such as a Fresnel pattern, which can correct light and improve the uniformity of light.

[0096] In a possible implementation manner, the optical texture 55 includes a plurality of annular grooves, such as circular ring-shaped grooves. The centers of the plurality of annular grooves coincide and are sleeved in sequence, and there is a spacing between two adjacent annular grooves.

[0097] Among them, the optical texture 55 corresponding to the flash lamp 43 plays a role in enhancing the dispersion of light and improving the intensity of the light transmitted from the flash lamp 43 through the lamp shade body 51 to the outside.

[0098] The lamp shade body 51 and the flange portion 52 can be an integrally connected whole part, ensuring the structural strength of the lamp shade body 51 itself.

[0099] In a possible implementation manner, a light blocking member 53 is provided inside the lamp shade body 51, and the light blocking member 53 blocks the edge of the light transmission area corresponding to the optical sensor 41.

[0100] The light blocking member 53 can be embedded inside the lamp shade body 51 so that when the light emitted by the ranging module 42 and the flash lamp 43 passes through the lamp shade body 51, it prevents the light from entering the optical sensor 41, thereby reducing interference with the normal operation of the optical sensor 41.

[0101] The area of the lamp shade body 51 corresponding to the flash lamp 43 can quickly disperse the light emitted by the flash lamp 43 to achieve the effect of filling light for the camera 10.

[0102] In a possible implementation manner, the smart terminal further includes a diffusion film 70, and the diffusion film 70 is disposed between the optical sensor 41 and the optical lamp shade 50. The diffusion film 70 can be pasted between the optical sensor 41 and the optical lamp shade 50, and the diffusion film 70 plays a role in correcting the light into a uniform surface light source to improve the optical diffusion angle.

[0103] In a possible implementation manner, the ranging module 42 is electrically connected to the control board 30. The light emitted by the ranging module 42 is blocked by an obstacle outside the smart terminal and reflected back to the optical sensor 41 to determine the distance from the obstacle to the smart terminal.

[0104] Optionally, the smart terminal is a mobile phone. When the user is answering a call, the user picks up the mobile phone and places it near the ear. The occluder outside the smart terminal is the user's head. The light emitted by the distance measurement module 42 is blocked by the user's head, and the light is reflected back to the optical sensor 41. The control board 30 can determine the distance between the occluder and the smart terminal according to the time difference between the time when the light is emitted from the distance measurement module 42 and the time when the light is reflected back to the optical sensor 41. Thus, when it is determined that the distance between the occluder and the smart terminal is less than or equal to a preset distance, the display screen 20 is turned off, achieving the effects of preventing accidental touch and saving energy consumption. When it is determined that the distance between the occluder and the smart terminal is greater than the preset distance, the display screen 20 can be turned on, or the display screen 20 is not turned off.

[0105] In a possible implementation manner, the optical sensor 41 is further configured to detect the ambient light intensity, and the control board 30 is further configured to adjust the brightness of the display screen 20 according to the ambient light intensity detected by the optical sensor 41. Detecting the ambient light intensity means detecting the ambient light strength.

[0106] To improve the usage effect, the number of the optical sensors 41, the distance measurement modules 42, and the flashlights 43 is not limited to 1 or 2, and multiple ones can also be set according to the usage requirements, and no specific limitation is made here.

[0107] In a possible implementation manner, the outer periphery of the optical sensor 41 is wrapped with a seal 90, such as a sealing rubber sleeve, to achieve the effect of light shielding and sealing. The optical sensor 41 has a light receiving port 411, and the position of the light receiving port 411 corresponds to the position of the mounting hole 24. The seal 90 wraps the outer periphery of the optical sensor 41, so that light can only enter the inside of the optical sensor 41 from the light receiving port 411, effectively blocking the interference of stray light and improving the usage effect of the optical sensor 41.

[0108] In a possible implementation manner, the seal 90 and the barrier 60 can be an integrally connected overall structure, made of the same material, to achieve the effect of blocking light. Such a structure is more convenient to install.

[0109] Reference Figure 1 and Figure 2 As shown in the figure, the present invention provides a smart terminal, which can be a foldable smart terminal, such as a foldable screen mobile phone. The foldable screen mobile phone includes two main bodies 80, and the two main bodies 80 can be distributed vertically or horizontally. As shown in the figure, Figure 7 The two main bodies 80 are connected with a main display screen 81, and at least one side of one of the main bodies 80 relative to the main display screen 81 has a secondary display screen 82, that is, the main display screen 81 and the secondary display screen 82 can be two opposite faces of the foldable screen mobile phone in the unfolded state.

[0110] Optionally, the main display screen 81 can be a flexible screen located on the inner surface of the foldable smart terminal. The flexible screen folds along with the foldable smart terminal. The above-mentioned display screen 20 can be a secondary display screen 82, which can be located on the outer surface of the foldable smart terminal. Through the cooperation of the optical sensor 41 and the ranging module 42 for detection, the anti-mis-touch function of the secondary screen of the foldable smart terminal can be effectively solved, and when the user is on a call, the main screen and the secondary screen can be turned off, achieving the effect of saving energy consumption.

[0111] The present utility model provides a smart terminal. Ambient light passes through the cover layer 21 and the optical lamp shade 50 and enters the optical sensor 41, or the ambient light directly passes through the optical lamp shade 50 and enters the optical sensor 41. The optical sensor 41 detects the intensity of the ambient light. When the optical sensor 41 detects a change in the intensity of visible light in the environment, the control board 30 adaptively adjusts the brightness of the display screen 20 according to the change in the intensity of the ambient light, so that the user has a better usage experience whether outdoors or indoors, whether during the day or at night.

[0112] When the user approaches the optical sensor 41, the infrared light or laser emitted by the ranging module 42 is blocked by the user, so that the infrared light or laser is reflected to the optical sensor 41. The optical sensor 41 determines the distance of the occluder, that is, the user, according to the detected intensity of the infrared light or laser, thereby realizing the extinguishing or lighting adjustment of the display screen 20 and achieving the anti-mis-touch function.

[0113] The present utility model provides a smart terminal. By integrating the optical sensor 41, the ranging module 42, and the flash 43, multiple functions are achieved with fewer components, so that the opening size of the mounting hole 24 is smaller, occupying less space, which is beneficial to increasing the screen-to-body ratio of the display screen 20 of the smart terminal.

[0114] A flexible screen, i.e., a flexible display screen, is used to display images. Exemplarily, the flexible screen can be an Organic Light-Emitting Diode (OLED) display screen, an Active-Matrix Organic Light-Emitting Diode (AMOLED) display screen, a Mini Organic Light-Emitting Diode display screen, a Micro Organic Light-Emitting Diode display screen, a Micro Organic Light-Emitting Diode display screen, or a Quantum Dot Light Emitting Diodes (QLED) display screen.
