In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Referring to fig. 3, a terminal device 10 includes a display 11, a depth camera 12, and an anti-reflection unit 13. The display screen 11 is used for displaying an image, and the depth camera 12 is arranged on one side of the display screen 11, which is opposite to the display image, and is used for acquiring a depth image of the object 20 to be measured; the anti-reflection unit 13 is disposed between the display screen 11 and the depth camera 12, and is used for preventing the reflected light beam of the display screen 11 from interfering with the acquisition of the depth image by the depth camera 12. It should be understood that the terminal device 10 may be an electronic device such as a mobile phone, a tablet computer, and a computer; in addition, not all the components are shown in the figure, and the terminal device 10 further includes other modules, for example, a power supply module for supplying power to the display screen 11, the depth camera 12, and the like; for example, a camera module may also be included for capturing color images and the like.
In one embodiment, the depth camera 12 emits a light beam to the surface of the object 20, and the light beam is reflected by the object 20 and then returns to the depth camera 12, so that the depth information of the object 20 can be calculated according to the flight time of the light beam. Referring to fig. 2, when the anti-reflection unit 13 is not provided in the terminal device 10, for convenience of description, the light beams emitted by the depth camera 12 include at least a first light beam 301 and a second light beam 302. The first light beam 301 is transmitted through the display screen 11 to the surface of the object 20 to be measured and reflected, the light beam reflected by the object 20 to be measured is marked as a third light beam 303, and the third light beam 303 can return to the depth camera 12 and is received by the depth camera 12; the second light beam 302 is reflected as it travels to the surface of the display screen 11, the light beam reflected by the display screen 11 is identified as a fourth light beam 304, and the fourth light beam 304 returns to the depth camera 12 to be received by the depth camera 12. At this time, the fourth light beam 304 reflected by the display screen 11 interferes with the third light beam 303, so that the depth information of the object 20 to be detected by the depth camera 12 is affected, and the depth camera 12 cannot accurately acquire the depth value of the object 20 to be detected, so that a clear depth image cannot be acquired.
In the embodiment, the anti-reflection unit 13 is disposed between the depth camera 12 and the display screen 11, so that the light beam reflected by the display screen 11 can be effectively prevented from affecting the detection result. Referring to fig. 3, in the process that the light beam generated by the depth camera 12 is transmitted to the object 20 to be measured, since the anti-reflection unit 13 is disposed between the depth camera 12 and the display screen 11, and the anti-reflection unit 13 can effectively block the light beam reflected by the display screen 11, the light beam generated by the depth camera 12 can be transmitted to the object 20 to be measured through the anti-reflection unit 13 and the display screen 11 and is reflected back to the depth camera 12 through the object 20 to be measured, thereby avoiding the influence of the light beam reflected by the display screen 11, facilitating to accurately obtain the depth value of the object 20 to be measured, and further obtaining a clear depth image.
Referring to fig. 1, in one embodiment, the depth camera 12 may be a ToF camera, and includes a transmitting module 121, a receiving module 122 and a control module 123, wherein the transmitting module 121 and the receiving module 122 are electrically connected to the control module 123. It should be understood that the depth camera 12 may also include other modules, such as a driving circuit module, a power supply module, etc., which are not all shown, but are not limited thereto. Of course, the depth camera 12 may be of other types as well, and is not limited thereto.

The laser 1211 may be a VCSEL (vertical cavity surface emitting laser) with a near infrared band, and since the ratio of the near infrared band in the solar spectrum is much lower than that of visible light, the detection efficiency of the silicon-based detector can substantially meet the detection requirement, and the interference of sunlight can be reduced to the maximum extent.
Specifically, in the embodiment, the wavelength of the laser 1211 may be 850nm to 940nm, for example, 850nm or 940 nm. The laser driver 1212 is connected to the laser 1211, and the laser driver 1212 includes a laser driving circuit therein for driving the laser 1211 to emit a high-frequency modulated light beam. The diffuser 1213 is connected to the laser 1211, and is configured to spatially modulate the light beam emitted by the laser 1211 into ideal surface illumination light, so that the laser illumination area and the field of view of the imaging system of the receiving module 122 are overlapped as much as possible, the utilization rate of the illumination light is maximized, and the detection accuracy is improved. The emitting module 121 is further provided with a beam exit port 1214, through which the beam modulated by the diffuser 1213 exits.
Referring to fig. 1, in one embodiment, the receiving module 122 includes a lens 1221, a filter 1222, and an image sensor 1223. The reflected light beam passes through the lens 1221 and the filter 1222 and then propagates to the image sensor 1223, and is processed by the image sensor 1223 and the control module 123 to obtain the depth value of the object 20 to be measured, and further obtain a depth image. The lens 1221 may be composed of one or more optical lenses for collecting the reflected light beam from the subject 20 and imaging on the image sensor 1223. The filter 1222 may select a narrow band filter matched to the wavelength of the light source (i.e., the wavelength of the light beam generated by the laser 1211) for suppressing background light noise in the remaining wavelength bands. The image sensor 1223 is an image sensor specifically used for optical time of flight (TOF) measurement, and may be, for example, a CMOS (complementary metal oxide semiconductor), APD (avalanche photodiode), SPAD (single photon avalanche photodiode), or the like. The receiving module 122 is further provided with a light beam incident port 1224, and the light beam reflected by the object to be measured 20 is incident through the light beam incident port 1224.
Referring to fig. 1, in an embodiment, the control module 123 is electrically connected to both the transmitting module 121 and the receiving module 122 for performing corresponding control operations, for example, the control module 123 may control the transmitting module 121 to transmit a light beam, control the receiving module 122 to receive a light beam, perform related calculations and processes on a received image, and the like. Of course, the control module 123 may perform other control operations, and is not limited to the above-mentioned case.
Referring to fig. 3, in an embodiment, an anti-reflection unit 13 is further disposed on a surface of the light beam exit port 1214 of the emission module 121, and since the light beam exit port 1214 is usually disposed with a glass device, such as a collimating lens, which has a reflection effect on the light beam, the anti-reflection unit 13 disposed on the light beam exit port 1214 can effectively avoid an influence of a reflected light beam generated by the device, thereby further improving an accuracy of the depth camera 12 for obtaining the depth value of the object 20 to be measured.
Referring to fig. 3, in an embodiment, the surface of the light beam incident port 1224 of the receiving module 122 is further provided with an anti-reflection unit 13, and since the light beam incident port 1224 is usually provided with a device made of glass, such as a collimating lens, which has a reflection effect on the light beam, the anti-reflection unit 13 disposed at the light beam incident port 1224 can effectively avoid the influence of the reflected light beam generated by the device, and further improve the accuracy of the depth camera 12 for obtaining the depth value of the object 20 to be measured.
It should be understood that the number of the anti-reflection units 13 may be set as required, and the anti-reflection units 13 may be disposed on the surface of the display screen 11, the surface of the light beam exit port 1214 of the transmitting module 121, and the surface of the light beam entrance port 1224 of the receiving module 122 (see fig. 3).
Referring to fig. 4, in an embodiment, the display panel 11 includes a glass cover 111 and a display panel 112 stacked together, and the depth camera 12 is disposed on a side of the display panel 112 opposite to the glass cover 111. The glass cover 111 is a layer directly contacting with the outside (for example, directly contacting with a finger), and can resist external impact, so as to protect the internal structure of the terminal device, and the display panel 112 is used for displaying images. The type of the display panel 112 may be set according to needs, and may be, for example, an LCD (liquid crystal display), an OLED (organic light emitting diode display), an IPS (In-Plane Switching) screen, an asv (advanced Super view) screen, and the like, which are not limited herein. At this time, the display screen 11 is a non-touch screen, that is, the display screen 11 is used only for displaying images.

The anti-reflection unit 13 is disposed on a side surface of the liquid crystal display module facing the backlight module.
In one embodiment, the display panel 112 is an oled display panel, and since the oled display panel is an active light emitting display panel and an organic material capable of emitting light under current driving is disposed in the display panel, a backlight module is not required. In this case, the anti-reflection unit 13 is disposed on a surface of the oled display panel facing the depth camera 12.
Referring to fig. 4, in an embodiment, the display screen 11 may also be a touch screen, in which case the display screen 11 further includes a touch sensor 113, and the touch sensor 113 is disposed between the glass cover 111 and the display panel 112, and is used for responding to an external touch operation, for example, when a finger of a user clicks the glass cover 111, the touch sensor 113 may sense the touch operation and respond. The touch sensor 113 may be a resistive touch sensor, a capacitive touch sensor, or another type, which is not limited herein.

Therefore, in order to ensure that the depth camera 12 can better receive the reflected light beam of the object 20 to be measured, an opening 110 may be opened in the display screen 11 at a position corresponding to the depth camera 12. The arrangement of the apertures 110 is different depending on the form of the display screen 11.

Referring to fig. 6, in an embodiment, the full field angle 401 corresponds to the light beam exit angle of the emitting module 121, and the cross-sectional area of the opening 110 may correspond to the light beam exit angle of the emitting module 121 in the depth camera 12 only, so that the size of the opening 110 in the display screen 11 may be reduced. Referring to fig. 5, in an embodiment, the cross-sectional area of the opening 110 is not smaller than the cross-sectional area 402 of the depth camera 12 on the side where the transmitting module 121 and the receiving module 122 are disposed, so as to ensure that the light beam generated by the transmitting module 121 can exit through the opening 110, and the external light beam can enter the receiving module 122 through the opening 110. Of course, the opening 110 may have other forms, and is not limited to the above-mentioned forms.
