[0022] FIG. 13 is a block diagram of an electronic device within a network environment according to various embodiments.
[0023] The electronic device may include a proximity sensor positioned below an active area of the display panel.
[0024] For example, the active area may refer to an area that includes subpixels available for displaying an image on the display panel. For example, since the active area is an area that is available (usable or available) for displaying an image, the active area may be referred to as a display area.
[0025] For example, the proximity sensor may be used to obtain data indicating whether an external object is adjacent to the electronic device (or the display panel). For example, the proximity sensor may be positioned below the active area (or the display area) to provide a wider active area (or the display area). The proximity sensor positioned below the active area may be exemplified within the description of FIG. 1.
[0026] FIG. 1 illustrates an exemplary electronic device including a proximity sensor positioned below an active area of a display panel.
[0027] Referring to FIG. 1, an electronic device (100) may include a display panel (110). For example, the display panel (110) may include an active area (120) and a non-active area (130). For example, the non-active area (130), unlike the active area (120), may be an area that is unusable or unavailable for displaying an image. For example, the non-active area (130) may refer to an area that does not include sub-pixels configured to emit light for displaying an image. For example, the non-active area (130) may refer to an area that includes dead sub-pixels. For example, the non-active area (130) may be included within the display panel (110) for light to a camera (135) (e.g., a front camera (135) (or selfie camera)) facing in a direction corresponding to the direction in which the display panel (110) faces. For example, the non-active area (130) may be aligned with a camera (135) positioned below the display panel (110). For example, the display panel (110) may further include another non-active area (not shown in FIG. 1) distinct from the non-active area (130). For example, the other non-active area may at least partially surround the active area (120).
[0028] For example, the proximity sensor (140) within the electronic device (100) may be positioned below the active area (120). For example, the proximity sensor (140) below the active area (120) may emit, transmit, or radiate light to acquire the data. For example, the light may be infrared light (or infrared waves). For example, the light may be an infrared (IR) vertical cavity surface emitting laser (VCSEL). However, the present invention is not limited thereto. For example, the proximity sensor (140) may emit the light to the outside through a portion of the active area (120) positioned above the proximity sensor (140) and receive the reflected light of the light. For example, the proximity sensor (140) can obtain data indicating whether an external object is adjacent to the electronic device (100) (or the display panel (110)) by including data on the amount of the reflected light (on). For example, the data can be obtained through an analog-to-digital converter (ADC) of the proximity sensor (140). The operation of the proximity sensor (140) emitting the light and the operation of the proximity sensor (140) obtaining the data can be exemplified within the description of FIG. 2.
[0029] Figure 2 shows a cross-sectional view taken along line A-A' of Figure 1.
[0030] Referring to FIG. 2, the proximity sensor (140) may be positioned below the active area (120) of the display panel (110). For example, the proximity sensor (140) may be disposed below a support member (210) (e.g., a metal plate (210)) that supports the active area (120) (or the display panel (110)). For example, the support member (210) may include an opening (290) (e.g., a hole, a slit, or a slot) aligned with the proximity sensor (140). As a non-limiting example, the alignment of the opening (290) with the proximity sensor (140) may indicate that the opening (290) includes the proximity sensor (140) when looking at the active area (120) in a second direction opposite to the first direction in which the active area (120) faces. As a non-limiting example, the alignment of the aperture (290) to the proximity sensor (140) may indicate that the aperture (290) overlaps the proximity sensor (140) when the active area (120) is viewed in the second direction. As a non-limiting example, the alignment of the aperture (290) to the proximity sensor (140) may indicate that the direction of an imaginary line extending from the center point of the aperture (290) to the center of the proximity sensor (140) is in the second direction. As a non-limiting example, the alignment of the aperture (290) to the proximity sensor (140) may indicate that light (260) from the transmitter circuit (201) (or transmitter, transmit unit, transmit part, transmission unit, transmission part, emitter, emitting unit, or emitting part) of the proximity sensor (140) is emitted to the outside through the aperture (290).As a non-limiting example, the alignment of the aperture (290) to the proximity sensor (140) may indicate that at least a portion of the reflected light (270) of the light (260) is received (or transmitted) from the outside through the aperture (290) to the receiving circuit (202) (or reiver, receive unit, receive part, reception unit, reception part, light receiver, light receive unit, or light reception part). As a non-limiting example, the size of the aperture (290) may be larger than the size of the proximity sensor (140). As a non-limiting example, the size of the aperture (290) may be the same as the size of the proximity sensor (140). As a non-limiting example, the size of the aperture (290) may be smaller than the size of the proximity sensor (140).
[0031] For example, the proximity sensor (140) can emit light (260) using the transmitter circuit (201). For example, the light (260) can be emitted externally through the aperture (290) and the active area (120). For example, the light (260) emitted externally can be reflected by an external object (200) around the electronic device (100) (or the display panel (110)).
[0032] For example, the proximity sensor (140) can receive reflected light (270) from an external object (200) using the receiving circuit (202). For example, the proximity sensor (140) can obtain data indicating whether the external object (200) is adjacent to the electronic device (100) (or display panel (110)) based on the amount of reflected light (270).
[0033] As in the above example, light (260) passing through the active region (120) may at least partially affect sub-pixels within the active region (120). For example, each of the sub-pixels may include a driving transistor (e.g., a field effect transistor (FET)). For example, light (260) passing through the active region (120) may cause a leakage current from a source (or source terminal) of the driving transistor to a drain (or drain terminal) of the driving transistor within the sub-pixels of the active region (120) located on (or within) the path of the light (260), depending on the wavelength of the light (260). The leakage current may be exemplified within the description of FIG. 3.
[0034] FIG. 3 illustrates an example of each of the sub-pixels within the active area of a display panel of an electronic device.
[0035] Referring to FIG. 3, each of the sub-pixels may include a light-emitting element (300) (or light-emitting diode (300)) (e.g., an organic light emitting diode (OLED)), a first transistor (301) (e.g., the driving transistor), a second transistor (302) (e.g., the switching transistor), a third transistor (303) (e.g., the compensation transistor), a fourth transistor (304) (e.g., the initialization transistor), a fifth transistor (305) (e.g., the operation control transistor), a sixth transistor (306) (e.g., the light-emitting control transistor), a seventh transistor (307) (e.g., a bypass transistor), a capacitor (309) (e.g., a storage capacitor), and / or a capacitor (310) (e.g., a boost capacitor). The components, their relationships, and their functions within each of the sub-pixels illustrated in FIG. 3 are exemplary only and do not limit the implementations described or claimed within this document.
[0036] For example, the gate of the first transistor (301) may be connected to the drain of the third transistor (303). For example, the gate of the first transistor (301) may be connected to the drain of the fourth transistor (304). For example, the gate of the first transistor (301) may be connected to a capacitor (309) used to store the data voltage (Vdata). For example, the gate of the first transistor (301) may be connected to a capacitor (310) used to compensate for a voltage drop caused by stopping providing the fourth signal (314). For example, the source of the first transistor (301) may be connected to the drain of the second transistor (302). For example, the source of the first transistor (301) may be connected to the drain of the fifth transistor (305). For example, the drain of the first transistor (301) may be connected to the source of the third transistor (303). For example, the drain of the first transistor (301) may be connected to the source of the sixth transistor (306). For example, the first transistor (301) may be used to provide a current (320) according to a data voltage (Vdata) to the light emitting element (300).
[0037] For example, the gate of the second transistor (302) may be configured to receive the fourth signal (314). For example, the source of the second transistor (302) may be configured to obtain the data voltage (Vdata).
[0038] For example, the gate of the third transistor (303) may be configured to receive the second signal (312).
[0039] For example, the gate of the fourth transistor (304) may be configured to receive the first signal (311). For example, the source of the fourth transistor (304) may be configured to obtain the first initialization voltage (Vint1) (e.g., about -3.5 (V)).
[0040] For example, the gate of the fifth transistor (305) may be configured to receive the light emission signal (315). For example, the source of the fifth transistor (305) may be configured to obtain the first driving voltage (VDD).
[0041] For example, the gate of the sixth transistor (306) may be configured to receive the light emitting signal (315). For example, the drain of the sixth transistor (306) may be connected to the source of the seventh transistor (307). For example, the drain of the sixth transistor (306) may be connected to the anode of the light emitting element (300).
[0042] For example, the gate of the seventh transistor (307) may be configured to receive the third signal (313). For example, the drain of the seventh transistor (307) may be configured to obtain the second initialization voltage (Vint2) (e.g., about -3 (V)).
[0043] For example, the cathode of the light emitting element (300) can be configured to obtain a second driving voltage (VSS).
[0044] For example, a display driving circuit (e.g., a display driving circuit (403) of FIG. 4) can initialize the gate of the first transistor (301) by providing a first signal (311) to the gate of the fourth transistor (304).
[0045] For example, the display driving circuit can initialize the anode of the light-emitting element (300) by providing the third signal (313) to the gate of the seventh transistor (307). For example, the anode can be initialized based on a second initialization voltage (Vint2). For example, the initialization of the anode can be performed to enhance the expression of black (or black color) using the light-emitting element (300).
[0046] For example, the display driving circuit can provide the data voltage (Vdata) to the gate of the first transistor (301) by providing a fourth signal (314) to each of the gate of the first transistor (301) and the gate of the second transistor (302). For example, providing the data voltage (Vdata) by providing the fourth signal (314) can be performed while the gate of the first transistor (301) is connected to the drain of the first transistor (301) via the third transistor (303) by providing a second signal (312) to the gate of the third transistor (303).
[0047] For example, the display driving circuit can provide a current (320) according to a data voltage (Vdata) to the light emitting diode (300) to emit light for displaying the second image. For example, the display driving circuit can provide a current (320) to the light emitting element (300) to display an image on the active area (120) of the display panel (110) by providing a light emitting signal (315) to each of the gate of the fifth transistor (305) and the gate of the sixth transistor (306).
[0048] For example, light (260) may cause a shifting of a threshold voltage (or threshold voltage) of the first transistor (301) depending on the wavelength of the light (260). For example, the threshold voltage may represent a minimum gate-to-source voltage (Vgs) of the first transistor (301) required to create a conducting path between the source of the first transistor (301) and the drain of the first transistor (301). For example, the shifting of the threshold voltage may cause a leakage current (390) from the source of the first transistor (301) to the drain of the first transistor (301), and the leakage current (390) may cause a change in brightness provided from the light-emitting diode driven through the driving transistor. As a non-limiting example, leakage current (390) may cause flickering (or photoelectric effect) within the active area (120). For example, the flickering may be uncomfortable to a user.
[0049] For example, the electronic device (100) may include a proximity sensor (140) positioned below the active region (120) and configured to emit a first light having a first wavelength (e.g., about 940 (nm)) or a second light having a second wavelength (e.g., about 1300 (nm)) longer than the first wavelength, to reduce the occurrence of the flicker. For example, the electronic device (100) may reduce the occurrence of the flicker by causing the proximity sensor (140) to adaptively emit the first light or the second light using at least one other component of the electronic device (100) that is distinct from the proximity sensor (140). Components of the electronic device (100) for reducing the occurrence of the flicker may be exemplified within the description of FIG. 4.
[0050] Figure 4 is a simplified block diagram of an exemplary electronic device.
[0051] Referring to FIG. 4, the electronic device (100) may include a processor (401), a display (402), and a proximity sensor (140).
[0052] For example, the processor (401) (e.g., including a processing circuit) may include at least a portion of the processor (1320) of FIG. 13, or may at least partially correspond to the processor (1320) of FIG. 13. For example, the processor (401) may execute instructions (at least temporarily) stored in a memory (not shown in FIG. 4) of the electronic device (100) (e.g., at least partially corresponding to the memory (1330) of FIG. 13), thereby performing the operations exemplified in the descriptions of FIGS. 5 to 12. For example, the instructions, when individually or collectively executed by the processor (401) (e.g., described as at least one processor), may cause the electronic device (100) to perform the operations exemplified in the descriptions of FIGS. 5 to 12.
[0053] For example, the processor (401) may control or cause the proximity sensor (140) to perform operations exemplified in the descriptions of FIGS. 5 to 12. For example, the processor (401) may control or cause the display driver circuit (403) to perform operations exemplified in the descriptions of FIGS. 5 to 12. For example, the processor (401) may be connected to the proximity sensor (140) and to the display driver circuit (403).
[0054] For example, the display (402) may include at least a portion of the display module (1360) of FIG. 13 or may correspond at least partially to the display module (1360) of FIG. 13. For example, the display (402) may include a display driving circuit (403) and a display panel (110). For example, the display driving circuit (403) may be used to display an image on an active area (120) of the display panel (110).
[0055] As a non-limiting example, the display driver circuit (403) may provide a synchronization signal (e.g., a TE (tearing effect) signal) to the processor (401) to display an image received from the processor (401). For example, the synchronization signal may represent a signal provided from the display driver circuit (403) to the processor (401) to prevent the processor (401) from transmitting another image to the display driver circuit (403) while the image is being displayed. For example, the synchronization signal may represent a signal provided from the display driver circuit (403) to the processor (401) to inform the processor (401) of the timing of image transmission from the processor (401) to the display driver circuit (403). For example, the synchronization signal may represent a signal provided from the display driver circuit (403) to the processor (401) prior to the start timing of a vertical synchronization signal used for displaying the image. For example, the provision of the synchronization signal from the display driver circuit (403) to the processor (401) may indicate that the display driver circuit (403) will display an image on the display panel (110). As a non-limiting example, the synchronization signal may be provided from the display driver circuit (403) to the processor (401) for a command mode of a display serial interface (DSI). As a non-limiting example, the synchronization signal may also be provided from the display driver circuit (403) to the processor (401) for a video mode of the DSI.
[0056] For example, the electronic device (100) may include a path for the synchronization signal. For example, the path may include a first path (451) from the display driving circuit (403) to the processor (401) (or a first path (451) between the processor (401) and the display driving circuit (403)) and a second path (452). For example, the first path (451) may be distinct from a path for an image transmitted from the processor (401) to the display driving circuit (403).
[0057] For example, the second path (452) may be used to provide the synchronization signal to the proximity sensor (140). For example, the synchronization signal may be provided from the display driving circuit (403) to the proximity sensor (140) via the second path (452) for adaptive operation of the proximity sensor (140).
[0058] Figure 4 illustrates an example in which the second path (452) is completely separated from the first path (451). However, unlike the illustration in Figure 4, the second path (452) may be divided from the first path (451) and extended to the proximity sensor (140).
[0059] For example, the proximity sensor (140) may include at least a portion of the sensor module (1376) of FIG. 13 or may at least partially correspond to the sensor module (1376) of FIG. 13. As a non-limiting example, the proximity sensor (140) may be used to identify the illuminance around the electronic device (100). For example, the proximity sensor (140) may include a transmitter circuit (201) and a receiver circuit (202). For example, the transmitter circuit (201) may include a first transmitter circuit (411) and a second transmitter circuit (412). For example, the first transmitter circuit (411) may be configured to emit the first light having the first wavelength. For example, the second transmitter circuit (412) may be configured to emit the second light having the second wavelength. For example, at least a portion of the first transmitting circuit (411) may be referred to as a first light source, and at least a portion of the second transmitting circuit (412) may be referred to as a second light source. For example, the receiving circuit (202) may be configured to receive reflected light of the first light. The receiving circuit (202) may be referred to as a light receiving unit. For example, the receiving circuit (202) may be configured to receive reflected light of the second light. For example, the receiving circuit (202) may include photodiodes for receiving the reflected light of the first light and the reflected light of the second light. Although not shown in FIG. 4, the receiving circuit (202) may also include a first receiving circuit for receiving the reflected light of the first light and a second receiving circuit for receiving the reflected light of the second light.
[0060] The display (402) may include a first state in which the display (402) is activated and a second state in which the display (402) is deactivated.
[0061] As a non-limiting example, the first state may include a state in which the display (402) is turned on, and the second state may include a state in which the display (402) is turned off. As a non-limiting example, the first state may include a state in which the first path (451) is activated, and the second state may include a state in which the first path (451) is deactivated. For example, the deactivation of the first path (451) may indicate that image transmission from the processor (401) to the display driving circuit (403) is stopped. As a non-limiting example, the first state may include a state for performance, and the second state may include a state for low power consumption. As a non-limiting example, the first state may include a state in which changing (or refreshing) of an image displayed on the display panel (110) is activated, and the second state may include a state in which changing of an image displayed on the display panel (110) is deactivated. For example, the deactivation of the change of the image may indicate that the image is maintained on the display panel (110). As a non-limiting example, the first state may include a state in which an image distinct from a black image is provided on the display panel (110), and the second state may include a state in which the black image is provided on the display panel (110). As a non-limiting example, the first state may include a state in which a user input causing a change in an execution screen of a software application being executed in the electronic device (100) is received within a reference time period, and the second state may include a state in which the user input is not received within the reference time period.As a non-limiting example, the first state may include a state in which power higher than the reference power is provided for driving the display (402), and the second state may include a state in which power lower than or equal to the reference power is provided for driving the display (402). For example, the reference power may be 0 (W). As a non-limiting example, the first state may include a state in which an image is displayed on the display panel (110) at a brightness level higher than the reference brightness level, and the second state may include a state in which an image is displayed on the display panel (110) at a brightness level lower than or equal to the reference brightness level.
[0062] For example, the processor (401), the display driving circuit (403), and the proximity sensor (140) may perform operations to reduce the leakage current or reduce the occurrence of the flicker. For example, the operations may include an operation of changing the light emitted from the proximity sensor (140) from the first light to the second light and an operation of identifying a condition for changing the light from the first light to the second light. The operations may be exemplified within the description of FIG. 5.
[0063] FIG. 5 illustrates an example of signaling within an electronic device that is executed to change the light emitted from a proximity sensor from a first light to a second light.
[0064] Referring to FIG. 5, in operation 501, the proximity sensor (140) may emit the first light to obtain the data indicating whether an external object (e.g., an external object (200)) is adjacent to the electronic device (100) (or the display panel (110)).
[0065] As a non-limiting example, the first light may be emitted while the display of an image on the display panel (110) is deactivated. For example, the first light may be emitted while a black color is provided through a portion of the active area (120) above the proximity sensor (140). For example, the first light may be emitted while the scan of the display driver circuit (403) executed to display an image on the display panel (110) is stopped. For example, the first light may be emitted while the transmission of an image from the processor (401) to the display driver circuit (403) is stopped.
[0066] For example, the first light may cause a leakage current from a source of a driving transistor (e.g., the first transistor (301)) within a subpixel of the active area (120) to a drain of the driving transistor. For example, the leakage current may cause flickering to occur within the active area (120). For example, the proximity sensor (140) may emit the first light while an image is not displayed on the active area (120) to reduce the occurrence of the flicker. As a non-limiting example, the first light may be periodically emitted according to a first duty ratio.
[0067] As a non-limiting example, the first light may be emitted while a black color is provided within a portion of the active area (120) positioned above the proximity sensor (140). For example, the electronic device (100) may support a mode (e.g., an always on display (AOD) mode) that displays an image while the processor (401) is in a sleep state or a low power state. For example, the processor (401) may provide a signal (or a flag signal) indicating that the AOD mode is activated to the proximity sensor (140) before the activation of the mode begins. For example, the proximity sensor (140) may emit the first light based on the signal. For example, an image displayed within the AOD mode may have a black color within a corresponding subregion within the portion. For example, since the subregion of the image displayed within the AOD mode has a black color, the proximity sensor (140) may emit the first light even when the image is displayed within the AOD mode. However, it is not limited to this.
[0068] As a non-limiting example, the portion of the active area (120) that the electronic device (100) identifies a color for determining the wavelength of light from the proximity sensor (140) may be associated with a portion of the active area (120) positioned over the proximity sensor (140). For example, if the color of the portion that has a larger size than the portion positioned over the proximity sensor (140) corresponds to the color black, the proximity sensor (140) may emit a first light. For example, the wavelength of the light emitted through the proximity sensor (140) may be changed based on the color of the portion of the active area (120) where blinking occurs due to the first light emitted from the proximity sensor (140). For example, the portion of the active area (120) that identifies a color for determining the wavelength of light from the proximity sensor (140) may be determined based on the size, position, and / or shape of a portion of the active area (120) that blinks due to the photoelectric effect while the first light is emitted.
[0069] In operation 502, the proximity sensor (140) may provide the data acquired while the first light is emitted to the processor (401). In the example of FIG. 5, the data may indicate that an external object is not adjacent to the electronic device (100) (or the display panel (110)). For example, the data indicating that an external object is not adjacent to the electronic device (100) may indicate an amount of reflected light of the first light that is less than a reference amount of light. For example, the data may be acquired through the proximity sensor (140) when the external object is spaced apart from the electronic device (100) (or the display panel (110)) by a distance greater than a certain distance.
[0070] For example, the processor (401) can obtain the data from the proximity sensor (140).
[0071] In operation 503, the processor (401) may, in response to the data indicating that an external object is not adjacent to the electronic device (100) (or the display panel (110)), provide the display driving circuit (403) with an image to be displayed on the display panel (110). As a non-limiting example, the processor (401) may provide the image to the display driving circuit (403) for the command mode. As a non-limiting example, the processor (401) may provide the image to the display driving circuit (403) for the video mode. As a non-limiting example, the image may be an image available for a call with a user of the external electronic device. For example, the image may include a user interface of a software application for a call.
[0072] For example, the display driving circuit (403) can obtain the image from the processor (401).
[0073] As a non-limiting example, but not shown in FIG. 5, the processor (401) may provide a command to the display driving circuit (403) indicating that it is to start providing the image before providing the image to the display driving circuit (403).
[0074] Although not illustrated in FIG. 5, the processor (401) may refrain from transmitting the image to the display driving circuit (403) in response to the data obtained while the first light is emitted and indicating that an external object is adjacent to the electronic device (100) (or the display panel (110)). Refraining from transmitting the image to the display driving circuit (403) will be exemplified within the description of FIG. 6.
[0075] In operation 504, the display driving circuit (403) may, in response to the command and / or the image, provide the synchronization signal to the processor (401) and / or the proximity sensor (140) before displaying the image on the display panel (110).
[0076] For example, the synchronization signal may be provided to the processor (401) from the display driving circuit (403) to prevent the processor (401) from providing another image to the display driving circuit (403) while the image is being displayed on the display panel (110) (or active area (120)) by the display driving circuit (403). For example, the processor (401) may obtain the synchronization signal from the display driving circuit (403).
[0077] For example, the synchronization signal may be provided from the display driving circuit (403) to the proximity sensor (140) to stop emitting the first light and emit the second light, as in operation 501, while the image is displayed on the active area (120). For example, since the second wavelength of the second light is longer than the first wavelength of the first light, the second light, unlike the first light, may reduce the occurrence of the leakage current. For example, the synchronization signal may be provided from the display driving circuit (403) to the proximity sensor (140) to reduce the occurrence of the flicker due to the leakage current while the image is displayed on the active area (120). For example, the proximity sensor (140) may obtain the synchronization signal from the display driving circuit (403).
[0078] For example, the synchronization signal may be provided to the processor (401) via a first path (451). For example, the synchronization signal may be provided to the proximity sensor (140) via a second path (452).
[0079] In operation 505, the display driving circuit (403) can display the image acquired in operation 503 on the display panel (110) (or active area (120)). For example, the image can be displayed based on a vertical synchronization signal that starts after the synchronization signal is provided to the processor (401) and / or the proximity sensor (140).
[0080] In operation 506, the proximity sensor (140) may, in response to the synchronization signal, emit the second light to acquire the data within a time period during which the image is displayed on the active area (120) (or display panel (110)). As a non-limiting example, the second light may be emitted periodically according to a second duty ratio. For example, the second duty ratio may be greater than the first duty ratio.
[0081] For example, the proximity sensor (140) may, in response to the synchronization signal, stop emitting the first light and emit the second light. For example, the proximity sensor (140) may, in response to the synchronization signal, change the light emitted from the proximity sensor (140) from the first light to the second light. For example, since the probability that the second light causes the flicker is lower than the probability that the flicker is caused by the first light, the electronic device (100) may, through the change from the first light to the second light, enhance the quality of the image displayed on the display panel (110).
[0082] For example, since the second light can reduce the occurrence of the flicker more than the first light, use of a method of emitting only the second light among the first light and the second light may be considered. However, since the second current provided to the proximity sensor (140) to emit the second light from the proximity sensor (140) is higher than the first current provided to the proximity sensor (140) to emit the first light from the proximity sensor (140), and the duty ratio used to emit the second light from the proximity sensor (140) is greater than the duty ratio used to emit the first light from the proximity sensor (140), power consumed by emitting the second light may be greater than power consumed by emitting the first light. For example, the electronic device (100) may emit the first light from the proximity sensor (140) during at least a portion of a time period during which an image is not displayed on the display panel (110) (or active area (120)), and may emit the second light from the proximity sensor (140) during a time period during which an image is displayed on the display panel (110) (or active area (120)), in order to reduce power consumed by the proximity sensor (140).
[0083] In operation 507, the proximity sensor (140) may provide the data acquired while the second light is emitted to the processor (401). For example, the processor (401) may acquire the data from the proximity sensor (140).
[0084] Periodically emitting the second light based on the second duty ratio may include changing the periodic emitting of the second light based on the first duty ratio to periodic emitting of the second light based on the second duty ratio. For example, the proximity sensor (140) may periodically emit the second light based on the first duty ratio. For example, the proximity sensor (140) may provide the data acquired while the second light is periodically emitted based on the first duty ratio to the processor (401). For example, the processor (401) may control or cause the proximity sensor (140) to change the first duty ratio to the second duty ratio in response to identifying that the data indicates that an external object is in proximity to the electronic device (100) (or the display panel (110)). For example, the proximity sensor (140) may, in response to the control of the processor (401), change the second light from periodically emitting light based on the first duty ratio to periodically emitting light based on the second duty ratio.
[0085] Providing the second current to the proximity sensor (140) to emit the second light may include changing the providing of the first current to the proximity sensor (140) to emit the second light to providing the first current to the proximity sensor (140) to emit the second light. For example, the processor (401) may provide the first current to the proximity sensor (140) to emit the second light. For example, the proximity sensor (140) may provide the data acquired while the second light is emitted based on the first current to the processor (401). For example, the processor (401) may change the first current provided to the proximity sensor (140) to the second current in response to identifying that the data indicates that an external object is in proximity to the electronic device (100) (or the display panel (110)).
[0086] As described above, FIG. 5 illustrates an operation when the data acquired while emitting the first light indicates that an external object is not adjacent to the electronic device (100) (or display panel (110)). An operation when the data acquired while emitting the first light indicates that an external object is adjacent to the electronic device (100) (or display panel (110)) can be illustrated within the description of FIG. 6.
[0087] FIG. 6 illustrates exemplary operations of a processor executed according to data acquired from a proximity sensor while the first light is emitted.
[0088] Referring to FIG. 6, in operation 601, the processor (401) may obtain the data acquired while the first light is emitted from the proximity sensor (140). For example, operation 601 may correspond to operation 502.
[0089] In operation 602, the processor (401) may identify, determine, or check whether the data acquired in operation 601 indicates that an external object is adjacent to the display panel (110) (or the active area (120)). For example, the processor (401) may execute operation 602 through a comparison between the reference light amount and the light amount indicated by the data. For example, the processor (401) may execute operation 603 in response to the data indicating that an external object is adjacent to the display panel (110), and may execute operation 604 in response to the data indicating that an external object is not adjacent to the display panel (110).
[0090] In operation 603, the processor (401) may keep the display driver circuit (403) from providing an image under the condition that the data indicates an external object adjacent to the display panel (110). For example, the processor (401) may refrain from providing the image to the display driver circuit (403) even if an image generated or acquired by the processor (401) exists. For example, the processor (401) may refrain from providing the image because the proximity of the external object to the display panel (110) may indicate that the user of the electronic device (100) is holding the electronic device (100) in contact with the ear for a call with a user of the external electronic device. Although not illustrated in FIG. 6, since the provision of the image from the processor (401) to the display driver circuit (403) is deactivated, the proximity sensor (140) may keep emitting the first light. However, the present invention is not limited thereto.
[0091] In operation 604, the processor (401) may activate providing an image to the display driving circuit (403) on the condition that the data indicates an external object that is not adjacent to the display panel (110). For example, it should be noted that the activation only indicates that the state of the processor (401) is capable of providing an image to the display driving circuit (403), and does not necessarily indicate that transmission of the image from the processor (401) to the display driving circuit (403) is executed.
[0092] In operation 605, the processor (401), after the activation, may provide the display driving circuit (403) with an image generated or acquired by the processor (401). For example, operation 605 may correspond to operation 503.
[0093] For example, operations related to the data acquired while the second light is emitted may be at least partially different from operations related to the data acquired while the first light is emitted (e.g., operations of FIG. 6). Operations related to the data acquired while the second light is emitted may be exemplified within the description of FIG. 7.
[0094] FIG. 7 illustrates exemplary operations of a processor executed according to data acquired from a proximity sensor while a second light is emitted.
[0095] Referring to FIG. 7, in operation 701, the processor (401) may obtain the data obtained while the second light is emitted from the proximity sensor (140). For example, operation 701 may correspond to operation 507.
[0096] In operation 702, the processor (401) may identify, determine, or check whether the data acquired in operation 701 indicates that an external object is adjacent to the display panel (110) (or the active area (120)). For example, the processor (401) may execute operation 702 by comparing a reference light quantity with a light quantity indicated by the data. For example, the reference light quantity may be the same as or different from the reference light quantity used in operation 602 of FIG. 6. For example, the processor (401) may execute operation 703 in response to the data indicating that an external object is not adjacent to the display panel (110), and may execute operation 704 in response to the data indicating that an external object is adjacent to the display panel (110).
[0097] In operation 703, the processor (401) may maintain the activation of providing an image to the display driving circuit (403) on the condition that the data indicates an external object not adjacent to the display panel (110). For example, the processor (401) may provide an image acquired by the processor (401) to the display driving circuit (403) based on a synchronization signal acquired from the display driving circuit (403) in response to the data indicating an external object not adjacent to the display panel (110).
[0098] In operation 704, the processor (401) may disable providing an image to the display driving circuit (403) on the condition that the data indicates an external object adjacent to the display panel (110). For example, the processor (401) may refrain from providing the image to the display driving circuit (403) even if an image generated or acquired by the processor (401) exists. For example, the processor (401) may refrain from providing the image because the proximity of the external object to the display panel (110) may indicate that the user of the electronic device (100) is putting the electronic device (100) in contact with the ear for a call with a user of the external electronic device.
[0099] Although not shown in FIG. 7, since providing an image from the processor (401) to the display driving circuit (403) is disabled, the display driving circuit (403) may stop providing the synchronization signal to the processor (401) under the condition that there is no image to be displayed on the display panel (110). For example, the proximity sensor (140) may, based on the stoppage of providing the synchronization signal, emit the first light to acquire the data. For example, the proximity sensor (140) may stop emitting the second light to acquire the data, based on the stoppage of providing the synchronization signal.
[0100] The operations of the proximity sensor (140) described in the description of FIG. 5 may also be exemplified as in the description of FIG. 8.
[0101] FIG. 8 illustrates exemplary operations of a proximity sensor that stops emitting a first light and emits a second light in response to a synchronization signal.
[0102] Referring to FIG. 8, in operation 801, the proximity sensor (140) may emit the first light to obtain the data indicating whether an external object is adjacent to the display panel (110). For example, the proximity sensor (140) may emit the first light while the synchronization signal is not obtained from the display driving circuit (403). For example, operation 801 may correspond to operation 501.
[0103] In operation 802, the proximity sensor (140) may obtain the synchronization signal provided from the display driving circuit (403) to the processor (401) to indicate the timing of providing an image to the display driving circuit (403) while the first light is emitted. For example, the synchronization signal may be provided from the display driving circuit (403) to the proximity sensor (140) via the second path (452). For example, operation 802 may correspond to operation 504.
[0104] In operation 803, the proximity sensor (140) may, in response to the synchronization signal, emit the second light to acquire the data. As a non-limiting example, the second light may be emitted using a duty ratio greater than the duty ratio used to emit the first light, based on a second current that is higher than the first current provided to the proximity sensor (140) to emit the first light. For example, the proximity sensor (140) may, in response to the synchronization signal, stop emitting the first light.
[0105] For example, since the synchronization signal is provided to the processor (110) before displaying an image on the display panel (110), the electronic device (100) can reduce flickering occurring within the active area (120) by emitting the first light by refraining from emitting the first light and emitting the second light within the time period during which the image is displayed.
[0106] For example, action 803 can correspond to action 506.
[0107] For example, since the power consumed by emitting the second light is greater than the power consumed by emitting the first light, the proximity sensor (140) may identify, check, or recognize whether operations are being performed to stop displaying an image on the display panel (110) (or the active area (120)) while the second light is being emitted. For example, the identification, the check, or the recognition may be performed for timing the stopping of emitting the second light and the emitting of the first light. The identification, the check, or the recognition may be exemplified within the description of FIGS. 9 and 10.
[0108] Figure 9 illustrates exemplary operations of a proximity sensor executed according to data acquired while the second light is emitted.
[0109] Referring to FIG. 9, in operation 901, the proximity sensor (140) may emit the second light to obtain the data. For example, operation 901 may correspond to operation 803.
[0110] In operation 902, the proximity sensor (140) may identify, check, or determine whether the data acquired while the second light is emitted indicates that an external object is adjacent to the display panel (110). For example, the proximity sensor (140) may execute operation 902 by comparing the amount of reflected light of the second light with a reference amount of light. As a non-limiting example, the reference amount of light used in operation 902 may be substantially the same as the reference amount of light illustrated for the description of operation 702.
[0111] For example, the comparison may be performed by a proximity sensor (140). For example, the comparison may be performed by a processor (401) based on the data obtained from the proximity sensor (140). However, the present invention is not limited thereto.
[0112] For example, the proximity sensor (140) may execute operation 903 when the data indicates that an external object is not adjacent to the display panel (110), and may execute operation 904 when the data indicates that an external object is adjacent to the display panel (110).
[0113] In operation 903, the proximity sensor (140) may continue to emit the second light under a condition in which the data indicates that the external object is not adjacent to the display panel (110). For example, since a state in which the external object is not adjacent to the display panel (11) may indicate a state in which an image can be displayed on the display panel (110), the proximity sensor (140) may continue to emit the second light in response to the data indicating that the external object is not adjacent to the display panel (110).
[0114] For example, when the comparison exemplified in operation 902 is executed by the processor (401), the proximity sensor (140) may continue to emit the second light based on receiving a signal from the processor (401) indicating that the second light should continue to be emitted. For example, when the comparison exemplified in operation 902 is executed by the processor (401), the proximity sensor (140) may continue to emit the second light based on identifying or confirming that no other signal indicating that the second light should be stopped or that the first light should be emitted is received from the processor (401). However, the present invention is not limited thereto.
[0115] In operation 904, the proximity sensor (140) may emit the first light under a condition that the data indicates that an external object is adjacent to the display panel (110). For example, since a state in which an external object is adjacent to the display panel (110) may indicate a state in which an image is not displayed on the display panel (110), the proximity sensor (140) may emit the first light in response to the data indicating that an external object is not adjacent to the display panel (110). For example, the proximity sensor (140) may stop emitting the second light under a condition in which the data indicates that an external object is adjacent to the display panel (110). For example, the proximity sensor (140) may emit the first light and stop emitting the second light to reduce power consumed by the proximity sensor (140).
[0116] For example, when the comparison illustrated in operation 902 is executed by the processor (401), the proximity sensor (140) may emit the first light and stop emitting the second light based on identifying or confirming that the other signal is received from the processor (401).
[0117] As described above, the electronic device (100) can reduce power consumption due to the use of the proximity sensor (140) by identifying whether an image can be displayed on the display panel (110) based on the data acquired through the proximity sensor (140).
[0118] FIG. 10 illustrates exemplary operations of a proximity sensor executed under the condition that acquisition of a synchronization signal is interrupted for a reference time while the second light is emitted.
[0119] Referring to FIG. 10, in operation 1001, the proximity sensor (140) may emit the second light to obtain the data. For example, operation 1001 may correspond to operation 803.
[0120] In operation 1002, the proximity sensor (140) may identify, check, or determine whether acquisition of the synchronization signal is interrupted for a reference time period. For example, the proximity sensor (140) may identify whether acquisition of the synchronization signal is interrupted for a reference time period by identifying whether the synchronization signal is newly (or additionally) acquired from the display driver circuit (403) during the reference time period from the timing at which the synchronization signal was most recently acquired from the display driver circuit (403). For example, the reference time period may be set to a time period at which the display driver circuit (403) may recognize that the image has stopped being displayed on the display panel (110) (or the active area (120)). As a non-limiting example, the reference time period may correspond to a minimum refresh rate among a plurality of refresh rates supported by the display driver circuit (403). As a non-limiting example, the reference time period may be 1 (second).
[0121] For example, the proximity sensor (140) can execute operation 1003 under the condition that obtaining the synchronization signal is not interrupted during the reference time, and can execute operation 1004 under the condition that obtaining the synchronization signal is interrupted during the reference time.
[0122] In operation 1003, the proximity sensor (140) can maintain emitting the second light while obtaining the synchronization signal is not interrupted for the reference time.
[0123] In operation 1004, the proximity sensor (140) may emit the first light in response to identifying that acquiring the synchronization signal has been interrupted for the reference time period. For example, the proximity sensor (140) may stop emitting the second light in response to identifying that acquiring the synchronization signal has been interrupted for the reference time period. For example, the proximity sensor (140) may emit the first light and stop emitting the second light in order to reduce power consumed by the proximity sensor (140).
[0124] As described above, the electronic device (100) can reduce power consumption due to the use of the proximity sensor (140) by identifying whether an image can be displayed on the display panel (110) based on the synchronization signal from the display driving circuit (403).
[0125] The above descriptions illustrate an example of identifying a condition for changing the light emitted from the proximity sensor (140) from the first light to the second light based on the synchronization signal from the display driving circuit (403). However, identifying the condition based on the synchronization signal from the display driving circuit (403) may be replaced with identifying the condition based on a signal from the processor (401). Identifying the condition based on a signal from the processor (401) may be exemplified within the description of FIG. 11.
[0126] FIG. 11 illustrates exemplary operations of a proximity sensor executed to change light emitted from the proximity sensor from a first light to a second light in response to a signal from a processor.
[0127] Referring to FIG. 11, in operation 1101, the proximity sensor (140) may emit the first light to obtain data indicating whether an external object is adjacent to the display panel (110). For example, the proximity sensor (140) may emit the first light while an image is not displayed on the display panel (110).
[0128] In operation 1102, the proximity sensor (140) may obtain a signal from the processor (401) indicating that displaying an image on the display panel (110) begins while the first light is emitted. For example, the signal may be provided to the proximity sensor (140) before displaying the image on the display panel (110) begins. For example, the signal obtained in operation 1102 may be provided to the proximity sensor (140) based on the processor (401) providing a VSS (vertical sync start) packet to the display driver circuit (403). For example, since the VSS packet is a packet provided to the display driver circuit (403) before providing an image to the display driver circuit (403), the signal provided based on the VSS packet may be used to control the light from the proximity sensor (140) before the image is displayed on the display panel (110).
[0129] In operation 1103, the proximity sensor (140) may, in response to the signal, emit the second light to acquire the data and stop emitting the first light to acquire the data. For example, emitting the second light may be maintained until another signal, as exemplified below, is acquired.
[0130] For example, the proximity sensor (140) may determine whether, while the second light is being emitted, another signal is received from the processor (401) indicating that displaying an image on the display panel (110) is to be terminated. For example, the proximity sensor (140) may, in response to the other signal received from the processor (401), stop emitting the second light and emit the first light. This operation may be exemplified within the description of FIG. 12.
[0131] FIG. 12 illustrates exemplary operations of a proximity sensor executed to change the light emitted from the proximity sensor from a second light to a first light in response to another signal from the processor.
[0132] Referring to FIG. 12, in operation 1201, the proximity sensor (140) may emit the second light. For example, operation 1201 may correspond to operation 1103.
[0133] In operation 1202, the proximity sensor (140) may obtain another signal from the processor (401) indicating that displaying an image on the display panel (110) is to be terminated while the second light is being emitted. For example, the another signal may be provided after displaying the last image on the display panel (110) is completed based on information about a refresh rate provided to the display driving circuit (403) from the processor (401).
[0134] In operation 1203, the proximity sensor (140) may, in response to the other signal, emit the first light and stop emitting the second light. For example, emitting the first light may be maintained until the signal illustrated in the description of FIG. 11 is acquired.
[0135] As a non-limiting example, and not as exemplified in the description of FIGS. 11 and 12, the first light may be emitted while an image is displayed on the display panel (110). For example, the processor (401) may obtain an image to be displayed on the display panel (110) and identify a color of a partial region of the image corresponding to a portion of the active area (120) above the proximity sensor (140). For example, the processor (401) may control the proximity sensor (140) to emit the first light even though the image is displayed on the display panel (140) based on identifying that the color is black. For example, the processor (401) may control the proximity sensor (140) to emit the second light based on identifying that the color is a different color distinct from black.
[0136] As another example, the processor (401) can identify a refresh rate for display on the display panel (110). For example, the processor (401) can control the proximity sensor (140) to emit the first light based on the refresh rate that is lower than the reference refresh rate. For example, since an image displayed based on the refresh rate that is lower than the reference refresh rate can be set in the electronic device (100) to have a black color within a partial area corresponding to the portion, the processor (401) can control the proximity sensor (140) to emit the first light. For example, the processor (410) can control the proximity sensor (140) to emit the second light based on the refresh rate that is higher than or equal to the reference refresh rate.
[0137] The operations exemplified in the above descriptions can be executed within the electronic devices exemplified below.

[0147] The sensor module (1376) can detect the operating status (e.g., power or temperature) of the electronic device (1301) or the external environmental status (e.g., user status) and generate an electrical signal or data value corresponding to the detected status.

[0154] The communication module (1390) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device (1301) and an external electronic device (e.g., electronic device (1302), electronic device (1304), or server (1308)), and the performance of communication through the established communication channel. The communication module (1390) may operate independently from the processor (1320) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (1390) may include a wireless communication module (1392) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (1394) (e.g., a local area network (LAN) communication module, or a power line communication module). Any of these communication modules may communicate with an external electronic device (1304) via a first network (1398) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (1399) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a local area network or a wide area network)). These various types of communication modules may be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (1392) may use subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (1396) to verify or authenticate the electronic device (1301) within a communication network such as the first network (1398) or the second network (1399).
[0155] The wireless communication module (1392) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency communications (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (1392) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (1392) may support various technologies for securing performance in high-frequency bands, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module (1392) may support various requirements specified in the electronic device (1301), an external electronic device (e.g., the electronic device (1304)), or a network system (e.g., the second network (1399)). According to one embodiment, the wireless communication module (1392) may support a peak data rate (e.g., 20 Gbps or more) for eMBB implementation, a loss coverage (e.g., 164 dB or less) for mMTC implementation, or a U-plane latency (e.g., 0.5 ms or less for downlink (DL) and uplink (UL), or 1 ms or less for round trip) for URLLC implementation.
[0156] The antenna module (1397) can transmit or receive signals or power to or from an external device (e.g., an external electronic device). In one embodiment, the antenna module (1397) may include an antenna including a radiator formed of a conductor or a conductive pattern formed on a substrate (e.g., a PCB). In one embodiment, the antenna module (1397) may include a plurality of antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication method used in a communication network, such as the first network (1398) or the second network (1399), may be selected from the plurality of antennas by, for example, the communication module (1390). A signal or power may be transmitted or received between the communication module (1390) and an external electronic device via the at least one selected antenna. In some embodiments, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (1397).
[0157] According to various embodiments, the antenna module (1397) may form a mmWave antenna module. In one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high frequency band.
[0158] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).
[0159] According to one embodiment, commands or data may be transmitted or received between the electronic device (1301) and an external electronic device (1304) via a server (1308) connected to a second network (1399). Each of the external electronic devices (1302 or 1304) may be the same or a different type of device as the electronic device (1301). According to one embodiment, all or part of the operations executed in the electronic device (1301) may be executed in one or more of the external electronic devices (1302, 1304, or 1308). For example, when the electronic device (1301) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (1301) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service. One or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (1301). The electronic device (1301) may process the result as is or additionally and provide it as at least a portion of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device (1301) may provide an ultra-low latency service by using distributed computing or mobile edge computing, for example. In another embodiment, the external electronic device (1304) may include an Internet of Things (IoT) device. The server (1308) may be an intelligent server utilizing machine learning and / or a neural network.According to one embodiment, an external electronic device (1304) or server (1308) may be included within the second network (1399). The electronic device (1301) may be applied to intelligent services (e.g., smart homes, smart cities, smart cars, or healthcare) based on 5G communication technology and IoT-related technology.
[0160] As described above, the electronic device (100) may include a processor (401), a display (402) including a display driving circuit (403) and a display panel (110), and a proximity sensor (140) positioned below an active area (120) of the display panel (110). For example, the processor (401) may be configured to obtain data from the proximity sensor (140) indicating whether an external object is adjacent to the display panel (110) while a first light having a first wavelength is emitted from the proximity sensor (140). For example, the first light may be emitted within a state in which a black color is provided through a portion of the active area above the proximity sensor (140). For example, the first light may be emitted while display of an image on the display panel (100) is inactive. For example, the first light may be emitted while the scan of the display driver circuit (403) is paused. For example, the processor (401) may be configured to, in response to the data acquired while the first light is emitted and indicating that an external object is not adjacent to the display panel (110), provide the display driver circuit (403) with an image to be displayed on the display panel (110). For example, the proximity sensor (140) may be configured to acquire a synchronization signal from the display driver circuit (403) according to the display of the image, which is provided to the processor (401) from the display driver circuit (403). For example, the proximity sensor (140) may be configured to, in response to the synchronization signal, emit a second light having a second wavelength longer than the first wavelength to acquire the data within a time period during which the image is displayed on the display panel (110).
[0161] For example, the proximity sensor (140) may be configured to stop emitting the first light in response to the synchronization signal.
[0162] For example, the processor (401) may be configured to maintain the inactivity of providing the image to the display driving circuit (403) based on the data obtained while the first light is emitted and indicating that an external object is adjacent to the display panel (110).
[0163] For example, the proximity sensor (140) may be configured to provide the data acquired while the second light is emitted to the processor (401). For example, the processor (401) may be configured to keep the provision of an image to the display driving circuit (403) based on the synchronization signal active while the data acquired from the proximity sensor (140) while the second light is emitted identifies that an external object is not adjacent to the display panel (110). For example, the processor (401) may be configured to deactivate the provision of an image to the display driving circuit (403) based on the synchronization signal in response to the data acquired from the proximity sensor (140) while the second light is emitted identifying that an external object is adjacent to the display panel (110). For example, the display driving circuit (403) may be configured to stop providing the synchronization signal to each of the processor (401) and the display driving circuit (403) based on the deactivation. For example, the proximity sensor (140) may be configured to emit the first light to obtain the data based on the stoppage of providing the synchronization signal.
[0164] For example, the proximity sensor (140) may be configured to stop emitting the second light based on the cessation of providing the synchronization signal.
[0165] For example, the display panel (110) may include sub-pixels. For example, each of the sub-pixels may include a light-emitting element and a driving transistor configured to obtain a current provided to the light-emitting element. For example, among the first light and the second light, the second light may be emitted from the proximity sensor (140) to reduce flickering that occurs within the active area (120) due to shifting of the threshold voltage of the driving transistor.
[0166] For example, the second light can be emitted from the proximity sensor (140) by providing the proximity sensor (140) with a second current that is higher than the first current provided to the proximity sensor (140) to emit the first light.
[0167] For example, the duty ratio used to emit the second light may be greater than the duty ratio used to emit the first light.
[0168] For example, the image may be displayed on the display panel (110) for communication with a user of the external electronic device.
[0169] As described above, the electronic device may include a processor (401), a display (402) including a display driving circuit (403) and a display panel (110), and a proximity sensor (140) positioned below an active area (120) of the display panel (110). For example, the proximity sensor (140) may be configured to emit a first light having a first wavelength to obtain data indicating whether an external object is adjacent to the display panel (110) while a black color is provided through a portion of the active area (120) above the proximity sensor (140). For example, the first light may be emitted while the display of an image on the display panel (100) is inactive. For example, the first light may be emitted while a scan of the display driving circuit (403) is stopped. For example, the proximity sensor (140) may be configured to obtain a synchronization signal provided from the display driving circuit (403) to the processor (401) to indicate a timing for providing an image to the display driving circuit (403) while the first light is emitted. For example, the proximity sensor (140) may be configured to emit a second light having a second wavelength longer than the first wavelength in response to the synchronization signal to obtain the data.
[0170] For example, the proximity sensor (140) may be configured to stop emitting the first light in response to the synchronization signal.
[0171] For example, the proximity sensor (140) may be configured to emit the first light based on acquiring data indicating that an external object is adjacent to the display panel (110) while the second light is emitted.
[0172] For example, the proximity sensor (140) may be configured to stop emitting the second light based on acquiring data indicating that an external object is adjacent to the display panel (110) while the second light is being emitted.
[0173] For example, the proximity sensor (140) may be configured to identify whether acquisition of the synchronization signal from the display driving circuit (403) is interrupted for a reference time while the second light is emitted. For example, the proximity sensor (140) may be configured to stop emitting the second light to acquire the data and emit the first light to acquire the data in response to identifying that acquisition of the synchronization signal is interrupted for the reference time. For example, the proximity sensor (140) may be configured to continue emitting the second light to acquire the data while acquisition of the synchronization signal is not interrupted for the reference time.
[0174] For example, the electronic device (100) may include a path between the display driving circuit (403) and the proximity sensor (140). The synchronization signal may be obtained from the display driving circuit (403) through the path.
[0175] As described above, the electronic device may include a processor (401), a display (402) including a display driving circuit (403) and a display panel (110), and a proximity sensor (140) positioned under an active area (120) of the display panel (110). For example, the proximity sensor (140) may be configured to emit a second light having a second wavelength to obtain data indicating whether an external object is adjacent to the display panel (110) based on obtaining a synchronization signal provided from the display driving circuit (403) to the processor (401) to indicate a timing for providing an image to the display driving circuit (403). For example, the proximity sensor (140) may be configured to identify whether additional obtaining of the synchronization signal is interrupted for a reference time. For example, the proximity sensor (140) may be configured to emit a first light having a first wavelength shorter than the second wavelength to acquire the data based on identifying that additional acquisition of the synchronization signal has been interrupted for the reference time.
[0176] For example, the proximity sensor (140) may be configured to continue emitting the second light based on identifying that additional acquisition of the synchronization signal is not interrupted during the reference time.
[0177] For example, the proximity sensor (140) may be configured to stop emitting the second light based on identifying that additional acquisition of the synchronization signal has been stopped for the reference time.
[0178] For example, the proximity sensor (140) may be configured to emit the first light based on the data acquired while the second light is emitted identifying that an external object is adjacent to the display panel (110).
[0179] For example, the proximity sensor (140) may be configured to stop emitting the second light based on the data acquired while the second light is being emitted identifying that an external object is adjacent to the display panel (110).
[0180] As described above, the electronic device (100) may include a processor (401), a display (402) including a display panel (110), and a proximity sensor (140) positioned below an active area (120) of the display panel (110). For example, the proximity sensor (140) may be configured to emit a first light having a first wavelength to obtain data indicating whether an external object is adjacent to the display panel (110). For example, the proximity sensor (140) may be configured to obtain a signal from the processor (401) while the first light is emitted, indicating that displaying an image on the display panel (110) begins. For example, the proximity sensor (140) may be configured, in response to the signal, to stop emitting the first light to acquire the data and to emit a second light having a second wavelength longer than the first wavelength to acquire the data.
[0181] For example, the proximity sensor (140) may be configured to obtain another signal from the processor (401) while the second light is being emitted, indicating that displaying an image on the display panel (110) is to be terminated. For example, the proximity sensor (140) may be configured, in response to the other signal, to stop emitting the second light to acquire the data and to emit the first light to acquire the data.
[0182] For example, emitting the second light may be maintained until the other signal is acquired.
[0183] For example, emitting the first light may be maintained until the signal is acquired.
[0184] For example, the signal may be provided to the proximity sensor (140) before starting to display an image on the display panel (110).
[0185] As described above, the electronic device (100) may include a proximity sensor (140) positioned below the display panel (110) and the active area (120) of the display panel (110), the proximity sensor including a first transmitting circuit configured to emit first light having a first wavelength, a second transmitting circuit configured to emit second light having a second wavelength longer than the first wavelength, and at least one receiving circuit configured to receive a reflection of the first light or the second light. For example, the proximity sensor (140) may be configured to drive the first transmitting circuit among the first transmitting circuit and the second transmitting circuit to obtain data indicating whether an external object is adjacent to the electronic device (100) based on the reflection light, according to a first state of the display panel (110). For example, the proximity sensor (140) may be configured to drive the second transmission circuit among the first transmission circuit and the second transmission circuit to obtain the data based on the reflected light, depending on the second state of the display panel (110).
[0186] For example, the duty ratio used by the second transmitting circuit driven to periodically emit the second light may be greater than the duty ratio used by the first transmitting circuit driven to periodically emit the first light.
[0187] For example, the magnitude of the current provided to the second transmitting circuit driven to emit the second light may be greater than the magnitude of the current provided to the first transmitting circuit driven to emit the first light.
[0188] For example, the electronic device may further include a processor. For example, the processor (401) may be configured to identify a state of the display panel (110). For example, the processor (401) may be configured to control the proximity sensor (140) to drive the first transmission circuit among the first transmission circuit and the second transmission circuit based on identifying that the state is the first state. For example, the processor (401) may be configured to control the proximity sensor (140) to drive the second transmission circuit among the first transmission circuit and the second transmission circuit based on identifying that the state is the second state.
[0189] For example, the first state may be a state that provides a black color within a portion of the active area (120) above the proximity sensor (140), and the second state may be a state that provides a different color distinct from the black color within the portion.
[0190] For example, the processor (401) may be configured to obtain an image to be displayed on the display panel (110) and identify whether the state is the first state or the second state by identifying whether a partial area of the image corresponding to the part is black.
[0191] For example, the processor (401) may be configured to identify a refresh rate for display on the display panel (110), and identify the state as the first state based on the refresh rate being lower than a reference refresh rate, and identify the state as the second state based on the refresh rate being higher than or equal to the reference refresh rate. For example, the refresh rate being lower than the reference refresh rate may be used within the electronic device (100) while the processor (401) is inactive in providing an image for display on the display panel (110), and an image displayed based on the refresh rate being lower than the reference refresh rate may have a black color within a partial region corresponding to the portion.
[0192] As described above, the electronic device may include a display and a proximity sensor for detecting an external object. The proximity sensor may be positioned below an active area (120) of the display (110) and may include at least two light sources having different wavelengths. The proximity sensor may include at least one light receiving unit configured to receive reflected light of the wavelengths. The at least two light sources may be selectively driven depending on a state of the electronic device.
[0193] For example, among the at least two light sources, the period during which the first light source of the first wavelength is driven may be shorter than the period during which the second light source of the second wavelength, which has a wavelength longer than the first wavelength, is driven.
[0194] For example, among the at least two light sources, while the first light source of the first wavelength is driven, the magnitude of the current input to the first light source may be smaller than the magnitude of the current input to the second light source of the second wavelength, which has a wavelength longer than the first wavelength, while the second light source of the second wavelength is driven.
[0195] For example, an electronic device may include at least one processor. The at least one processor may be configured to control the at least two light sources of the proximity sensor based on a state of the electronic device. The state of the electronic device may include a first state in which the display is activated and a second state in which the display is deactivated.
[0196] For example, the at least one processor may be configured to drive, within the second state, a first light source of a first wavelength among the at least two light sources. The at least one processor may be configured to drive, within the first state, a second light source of a second wavelength longer than the first wavelength among the at least two light sources.
[0197] For example, the second state may be a state that provides a black color within a portion of the active area above the proximity sensor. The first state may be a state that provides a different color distinct from the black color within the portion.
[0198] For example, the at least one processor may be configured to obtain an image to be displayed on the display. The at least one processor may be configured to identify whether the state is the first state or the second state by identifying whether a subregion of the image corresponding to the portion is the black color.
[0199] For example, the at least two light sources may be selectively driven depending on a state of the electronic device, which is distinguished by a synchronization signal provided from a display driving circuit of the display to the at least one processor according to the display of an image on the display.
[0200] For example, based on the synchronization signal, during a time period in which the image is displayed on the display, the second light source among the first light source of the first wavelength and the second light source of the second wavelength longer than the first wavelength may be driven.
[0201] For example, the proximity sensor may be located below the active area of the display panel within the display.
[0202] For example, the electronic device may include at least one processor including a processing circuit and a memory storing instructions and including one or more storage media. For example, the display may include a display driving circuit. The at least two light sources may include a first light source of a first wavelength and a second light source of a second wavelength. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to control the proximity sensor to drive the second light source of the second wavelength in response to a synchronization signal provided to the at least one processor from the display driving circuit.
[0203] For example, the instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to control the proximity sensor to stop driving the first light source of the first wavelength in response to a synchronization signal provided to the at least one processor from the display driving circuit.
[0204] For example, the instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to disable providing an image to the display based on data obtained from the proximity sensor while driving the first light source of the first wavelength, the data indicating that an external object is proximate to the display.
[0205] For example, the instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to stop providing an image to the display in response to the synchronization signal based on data obtained from the proximity sensor while driving the second light of the second wavelength, the data indicating that an external object is proximate to the display.
[0206] For example, the instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to maintain providing an image to the display in response to the synchronization signal based on data obtained from the proximity sensor while driving the second light of the second wavelength, the data indicating that an external object is not adjacent to the display.
