[0002] With the rapid development of mobile communication technology, electronic devices such as mobile phones and tablet computers have become indispensable devices in people's daily lives. In order to enable electronic devices to automatically adjust screen brightness and color temperature and other parameters in environments with different brightness, electronic devices are equipped with ambient light sensors, which can obtain ambient light information and feed it back to the processor, so that the processor can adjust screen brightness and color temperature and other parameters according to the obtained ambient light information to optimize the user experience of the electronic device.

[0003] However, the information currently obtained by the sensor is affected by the light information of the screen itself. When the ambient light sensor is working, the ambient light received is also mixed with the light emitted by the screen itself, and the ambient light and screen light are difficult to separate. This causes the values ​​reported by the ambient light sensor to be inconsistent with the ambient light conditions. Once this data is used by electronic devices, the electronic devices will be configured with screen brightness and picture color that do not meet the current environmental conditions, resulting in a poor user experience or even discomfort.

[0033] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0034] In the related art, in order to provide users with a better display experience, many electronic devices tend to use full screens, and the ambient light sensor needs to be set inside or under the screen. This makes it impossible for the ambient light sensor to obtain ambient light information by setting openings in the non-display area, and it is necessary to avoid the influence of the screen's own light on the ambient light sensor.

[0035] When the screen is on, the ambient light sensor will be in a frequently intermittent working state. The ambient light received by the ambient light sensor is also mixed with the light emitted by the screen itself, and it is difficult to separate the ambient light and the screen light. This causes the values ​​reported by the ambient light sensor to be inconsistent with the ambient light conditions. Once this data is used by electronic devices, the electronic devices will be configured with screen brightness and picture color that do not meet the current environmental conditions, resulting in a poor user experience or even discomfort.

[0036] In order to solve the above technical problems, according to an embodiment of the present disclosure, a display component is provided, wherein the display component includes: a screen, wherein the screen includes a plurality of pixel rows, wherein the pixel rows include a lit state and an unlit state when driven; a driving circuit, wherein the driving circuit drives the pixel rows to switch to a lit state or an unlit state; and a sensor, wherein the sensor is used to obtain ambient light parameters, and the sensor is electrically connected to the driving circuit, wherein when the driving circuit controls the pixel rows to be in the lit state, the sensor receives an electrical signal from the driving circuit and performs sampling after a delay time according to the electrical signal; and when the driving circuit controls the pixel rows to be in the unlit state, the sensor receives the electrical signal from the driving circuit and performs sampling.

[0037] The present disclosure achieves a signal connection between the driving circuit and the sensor so that the sensor can accurately know whether the pixel row is on or off, and can accurately know the time points when the pixel row where the sensor is located is luminous and non-luminous, thereby avoiding the influence of delays in the process of transmitting screen parameters from the mainboard, so that the sampling delay time can be accurately confirmed, avoiding interference with sensor sampling when the screen is luminous, and improving the single sampling accuracy of the sensor, thereby avoiding increasing the number of samples and increasing the processing algorithm, and improving system power consumption.

[0038] It can be understood that the display component involved in the present disclosure can be applicable to any terminal listed below.

[0039] It is understandable that the terminal involved in the present disclosure may also be referred to as a terminal device, a user equipment (User Equipment, UE), a mobile station (Mobile Station, MS), a mobile terminal (Mobile Terminal, MT), etc., which is a device that provides voice and / or data connectivity to users. For example, the terminal may be a handheld device with a wireless connection function, a vehicle-mounted device, etc. At present, some examples of terminals are: a smart phone (Mobile Phone), a pocket computer (Pocket Personal Computer, PPC), a handheld computer, a personal digital assistant (Personal Digital Assistant, PDA), a laptop computer, a tablet computer, a wearable device, or a vehicle-mounted device, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device may also be a vehicle-mounted device. It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

[0040] Figure 1 The figure is a schematic diagram showing the connection relationship of a display component according to an exemplary embodiment. Figure 2 The diagram is a schematic structural diagram of an electronic device according to an exemplary embodiment.

[0041] In some embodiments, Figure 1 and Figure 2 As shown, the display component may include: a screen 1 , a driving circuit 3 and a sensor 4 .

[0042] Screen 1 can emit light and display images. Screen 1 may include multiple pixel rows 2. When pixel rows 2 are driven, they may include a lit state and an unlit state. Pixel rows 2 in the lit state may emit light, and pixel rows 2 in the unlit state may not emit light. When pixel rows 2 of screen 1 are in the lit state, screen 1 can emit light and display images. And pixel rows 2 can switch between the lit state and the unlit state at a high frequency, achieving high-frequency flickering that is difficult for the user's naked eye to detect. By scanning new image information line by line to pixel rows 2 or multiple pixel rows 2, the scanning and refreshing of screen 1 can be completed, thereby achieving the refresh of the image displayed on screen 1.

[0043] The driving circuit 3 can be used to drive the pixel row 2 and switch the pixel row 2 to a lit state or an unlit state. The driving circuit 3 can include multiple driving circuits 3, and the driving circuits 3 can correspond to the pixel rows 2 one by one. Each driving circuit 3 controls one pixel row 2, thereby achieving precise control of the pixel row 2.

[0044] The sensor 4 may be used to obtain ambient light parameters. For example, the sensor 4 may obtain ambient light intensity.

[0045] The sensor 4 can be electrically connected to the driving circuit 3, so that when the driving circuit 3 controls the pixel row 2 to light up or go out, the sensor 4 can also receive the electrical signal from the driving circuit 3, thereby knowing the lighting state of the pixel row 2 in a specific row, and the position of the pixel row 2 in a specific row and the distance from the sensor 4 can be preset, controlled and determined. Therefore, according to the scanning frequency of the screen 1, the sensor 4 can calculate and accurately obtain the lighting time of any pixel row 2, so that the sensor 4 can perform sampling after the delay time of the received electrical signal interval, when the pixel rows 2 above the sensor 4 are all in the off state and will not interfere with the sensor 4.

[0046] Exemplarily, when the driving circuit 3 sends an electrical signal to control the pixel row 2 to be in a light-on state, the sensor 4 can synchronously receive the electrical signal of the driving circuit 3, and the sensor 4 can perform sampling after an interval delay time;

[0047] When the driving circuit 3 sends an electrical signal to control the pixel row 2 to be in an off state, the sensor 4 can synchronously receive the electrical signal from the driving circuit 3 and the sensor 4 can perform sampling.

[0048] By establishing a signal connection between the driving circuit 3 and the sensor 4, the sensor 4 can accurately know whether the pixel row 2 is on or off, so that the sensor 4 can accurately know the time points when the pixel row 2 where the sensor 4 is located is luminous and non-luminous, avoiding the influence of delays in the process of transmitting the parameters of the screen 1 from the mainboard 5, so that the sampling delay time can be accurately confirmed, avoiding interference with the sampling of the sensor 4 when the screen 1 is luminous, and improving the single sampling accuracy of the sensor 4, thereby avoiding increasing the number of samples and increasing the processing algorithm, and improving the system power consumption.

[0049] In some embodiments, the screen 1 may be an organic light emitting display screen.

[0050] In some embodiments, Figure 2 As shown, the screen 1 may include a pixel layer, and the sensor 4 may be disposed in the pixel layer. By disposing the sensor 4 in the pixel layer, the non-display area reserved for the sensor 4 on the screen 1 is omitted, thereby improving the screen-to-body ratio of the screen 1 and improving the viewing experience of the user when viewing the screen 1.

[0051] Figure 3 The diagram is a schematic structural diagram of an electronic device according to an exemplary embodiment. Figure 4 is a cross-sectional structural diagram of a display assembly according to an exemplary embodiment.

[0052] In some embodiments, Figure 3 and Figure 4 As shown, the screen 1 may include a light-emitting surface 11, a non-light-emitting surface 12 opposite to the light-emitting surface 11, and a light-shielding layer 13. One side of the sensor 4 may be disposed on a side of the light-shielding layer 13 away from the light-emitting surface 11 and the non-light-emitting surface 12, and the other side of the sensor 4 may be disposed on other components that can provide an installation position, for example, Figure 3 As shown, the other side of the sensor 4 can be arranged on a main board 5 of the electronic device.

[0053] like Figure 4 As shown, the light shielding layer 13 may be provided with an opening 14 for ambient light to enter, and the opening 14 may face the sensor 4, and the ambient light may enter the sensor 4 through the opening 14. The opening 14 may be an opening 14 formed by changing the density of the pixel arrangement inside the pixel row 2, or may be an opening 14 formed by a transparent light-guiding material.

[0054] By arranging the sensor 4 on the side of the shading layer 13 away from the light-emitting surface 11, the non-display area reserved for the sensor 4 on the screen 1 is eliminated, thereby improving the screen-to-body ratio of the screen 1 and improving the viewing experience of the user when viewing the screen 1.

[0055] In some embodiments, Figure 1 As shown, the display assembly may include: a detection circuit, one end of the detection circuit 6 may be electrically connected to the sensor 4, and the other end of the detection circuit 6 may be electrically connected to the drive circuit 3. The detection circuit 6 may be used to transmit the electrical signal of the drive circuit 3.

[0056] When the driving circuit 3 controls the pixel row 2 to switch to the on state or the off state, the sensor 4 can receive the electrical signal from the driving circuit 3 through the detection line 6, so that the sensor 4 can accurately know the on and off state of the pixel row 2 in a specific row.

[0057] Exemplarily, when the driving circuit 3 drives the pixel row 2 to switch from an off state to an on state, the driving circuit 3 can send a high-level signal, and the sensor 4 can receive the high-level signal from the driving circuit 3 through the detection line 6, thereby accurately knowing that the pixel row 2 of a specific row is switched to the on state.

[0058] When the driving circuit 3 drives the pixel row 2 to switch from the on state to the off state, the driving circuit 3 can send a low-level signal, and the sensor 4 can receive the low-level signal from the driving circuit 3 through the detection line 6, thereby accurately knowing that the pixel row 2 of a specific row is switched to the off state.

[0059] In some embodiments, Figure 1As shown, the screen 1 may include a detection area 10, and the ambient light may reach the sensor 4 through the detection area 10. The detection area 10 may be an area formed by the ambient light that can enter the sensor 4 and is irradiated on the screen 1, that is, the ambient light irradiated on the detection area 10 may be collected by the sensor 4.

[0060] Among them, when the screen 1 is lit, the detection area 10 may have a state in which pixel rows 2 in the detection area 10 are simultaneously in an off state. When the sensor 4 performs sampling when the pixel rows 2 in the detection area 10 are simultaneously in an off state, the sampling of the sensor 4 may not be disturbed by the light emitted by the screen 1 itself, thereby obtaining accurate ambient light parameters.

[0061] Based on the same concept, the present disclosure also provides a display device.

[0062] In some embodiments, the display device may include a display component. The display device may be a component that has the function of converting an electrical signal into a luminous image. The display device achieves a signal connection between the drive circuit 3 and the sensor 4, so that the sensor 4 can accurately know the light and dark of the pixel row 2, so that the sensor 4 can accurately know the time point when the pixel row 2 where the sensor 4 is located emits light and does not emit light, avoiding the delay effect in the process of transmitting the parameters of the screen 1 from the mainboard 5, so that the sampling delay time can be accurately confirmed, avoiding interference with the sampling of the sensor 4 when the screen 1 emits light, improving the single sampling accuracy of the sensor 4, thereby avoiding increasing the number of samples and increasing the processing algorithm, and improving the system power consumption.

[0063] Figure 5 is a flow chart of a sensor sampling method according to an exemplary embodiment.

[0064] Based on the same concept, the present disclosure also provides a sensor sampling method, which can be applied to a display component or a display device.

[0065] like Figure 5 As shown, a sensor sampling method shown in an implementation example includes:

[0066] S10: In response to the electrical signal received from the driving circuit 3, determining the display state of the pixel row 2; the display state may include an off state and an on state;

[0067] S20: In response to the pixel row 2 being in the off state, controlling the sensor 4 to perform sampling;

[0068] S30: In response to the pixel row 2 being in the light-on state, determining the delay time of the sampling of the sensor 4, and controlling the sensor 4 to perform sampling after the delay time.

[0069] The electrical signal of the driving circuit 3 may be an electrical signal for driving the pixel row 2 to change the display state, and the display state of the pixel row 2 may be accurately known by receiving the electrical signal. The pixel row 2 may be a pixel row 2 located in the detection area 10 .

[0070] Exemplarily, when the driving circuit 3 drives the pixel row 2 to switch from an off state to an on state, the driving circuit 3 can send a high-level signal, and the sensor 4 can receive the high-level signal from the driving circuit 3 through the detection line 6, thereby accurately knowing that the pixel row 2 of a specific row is switched to the on state.

[0071] The off state of the pixel row 2 may be a state in which the pixel row 2 does not emit light, and the on state of the pixel row 2 may be a state in which the pixel row 2 emits light.

[0072] In the embodiment of the present disclosure, a signal is first received from the driving circuit 3 to determine the display state of the specific pixel row 2. When the display state of the specific pixel row 2 is off, the sensor 4 can directly perform sampling. When the display state of the specific pixel row 2 is on, the sensor 4 can determine that the pixel row 2 in the detection area 10 is off after the interval delay time, and then perform sampling again after the interval delay time.

[0073] Figure 6 is a flow chart of a sensor sampling method according to an exemplary embodiment. Figure 6 As shown, a sensor sampling method shown in an implementation example includes:

[0074] S10: In response to the electrical signal received from the driving circuit 3, determining the display state of the pixel row 2; the display state may include an off state and an on state;

[0075] S20: In response to the pixel row 2 being in the off state, controlling the sensor 4 to perform sampling;

[0076] S31: In response to the pixel row 2 being in the light-on state, according to the scanning cycle of the driving circuit 3, it is determined that the pixel row 2 is in the light-off state after a first time, and the first time is determined as the delay time.

[0077] The scanning cycle of the driving circuit 3 is the period in which the driving circuit 3 controls the pixel row 2 to turn on and off, and is the same as the scanning cycle frequency of the screen 1.

[0078] In the disclosed embodiment, a signal is first received from the driving circuit 3 to determine the display state of the specific pixel row 2. When the display state of the specific pixel row 2 is off, the sensor 4 can directly perform sampling. When the display state of the specific pixel row 2 is on, the current scanning cycle of the driving circuit 3 can be obtained. For example, since the scanning cycle change is relatively fixed and will last for a certain period of time, the current scanning cycle of the driving circuit 3 can be obtained and stored from the mainboard 5 of the electronic device. Since the position of the specific pixel row 2 is a known parameter that can be controlled during design, the time when the detection area 10 is off can be accurately calculated by combining the position of the specific pixel row 2, the display state of the specific pixel row 2 and the scanning cycle of the driving circuit 3, thereby determining the length of the delay time. The sensor 4 is sampled after the interval delay time, thereby avoiding interference with the sampling of the sensor 4 when the screen 1 is luminous, improving the single sampling accuracy of the sensor 4, thereby avoiding increasing the number of samples and the processing algorithm, and improving the system power consumption.

[0079] In some embodiments, the driving circuit 3 can be set to multiple lines, and the sensor 4 can further improve the accuracy of determining the on and off state of the screen 1 by receiving level signals from multiple driving circuits 3.

[0080] Figure 7 is a flow chart of a sensor sampling method according to an exemplary embodiment. Figure 7 As shown, a sensor sampling method shown in an implementation example includes:

[0081] S10: In response to the electrical signal received from the driving circuit 3, determining the display state of the pixel row 2; the display state may include an off state and an on state;

[0082] S20: In response to pixel row 2 being in the off state, control sensor 4 to perform sampling

[0083] S321: In response to pixel row 2 being in a light-on state;

[0084] S322: determining a scanning period of the driving circuit 3 according to the scanning signals of the plurality of driving circuits 3 being transmitted in a first period;

[0085] S323: According to the scanning cycle, determine that the pixel row 2 is in the off state after the first time, and determine the first time as the delay time.

[0086] The first cycle is the transmission cycle of the electrical signals of the multiple driving circuits 3. By simultaneously determining the transmission cycles of the electrical signals of the multiple driving circuits 3, the on and off change cycles of the multiple pixel rows 2 in the same time can be known, and the scanning cycle of the current driving circuit 3 can be determined.

[0087] In the disclosed embodiment, a signal is first received from the driving circuit 3 to determine the display state of the specific pixel row 2. When the display state of the specific pixel row 2 is off, the sensor 4 can directly perform sampling. When the display state of the specific pixel row 2 is on, it can be determined by transmitting multiple scanning signals of the driving circuit 3 in the first cycle, and then the current scanning cycle of the driving circuit 3 is calculated through the first cycle. Since the position of the specific pixel row 2 is a known parameter that can be controlled during design, the time when the detection area 10 is off can be accurately calculated by combining the position of the specific pixel row 2, the display state of the specific pixel row 2 and the scanning cycle of the driving circuit 3, thereby determining the length of the delay time. The sensor 4 is sampled after the interval delay time, thereby avoiding interference with the sampling of the sensor 4 when the screen 1 is luminous, improving the single sampling accuracy of the sensor 4, thereby avoiding increasing the number of samples and the processing algorithm, and improving the system power consumption.

[0088] In some embodiments, Figure 1 As shown, the screen 1 may include a detection area 10 , and the pixel rows 2 may include a first pixel row 21 located in the detection area 10 and a second pixel row 22 located outside the detection area 10 .

[0089] Figure 8 1 is a flow chart of a sensor sampling method according to an exemplary embodiment. The sensor sampling method according to an exemplary embodiment includes:

[0090] S11: In response to the electrical signal received from the driving circuit 3, determining the display state of the pixel row 2 located outside the detection area 10;

[0091] S12 : In response to the display state of the pixel row 2 outside the detection area 10 , the display state of the pixel row 2 within the detection area 10 is determined according to the scanning cycle of the driving circuit 3 .

[0092] S24: in response to the pixel row 2 located in the detection area 10 being in an off state, controlling the sensor 4 to perform sampling;

[0093] S32: In response to the pixel row 2 located in the detection area 10 being in the light-on state, according to the scanning cycle of the driving circuit 3, it is determined that the pixel row 2 located in the detection area 10 is in the light-off state after a first time, and the first time is determined as the delay time.

[0094] In the embodiment disclosed in the present invention, a signal is first received from the driving circuit 3 to determine the display state of the pixel row 2 located outside the detection area 10. Since the position of the pixel row 2 located outside the detection area 10 and the position of the pixel row 2 located within the detection area are known parameters that can be controlled during design, when the display state of a certain row of pixel rows 2 changes, the state of any other row of pixel rows 2 can be calculated by combining the scanning cycle of the driving circuit 3. Therefore, the display state of the pixel row 2 located within the detection area 10 can be accurately calculated by combining the position of the pixel row 2 located within the detection area 10, the position of the pixel row 2 located outside the detection area 10 and the scanning cycle of the driving circuit 3.

[0095] When the display state of the pixel row 2 in the detection area 10 is off, the sensor 4 can directly perform sampling. When the display state of the pixel row 2 in the detection area 10 is on, the time when the detection area 10 is off can be accurately calculated by combining the position of the pixel row 2 in the detection area 10, the display state of the pixel row 2 outside the detection area 10, and the scanning cycle of the driving circuit 3, thereby determining the length of the delay time. The sensor 4 is sampled after the interval delay time, thereby avoiding interference with the sampling of the sensor 4 when the screen 1 is luminous, improving the single sampling accuracy of the sensor 4, thereby avoiding increasing the number of samples and the processing algorithm, and improving the system power consumption.

[0096] Exemplarily, a signal is first received from the driving circuit 3 to determine the display state of the second pixel row 22 located outside the detection area 10. Since the position of the second pixel row 22 and the position of the first pixel row 21 are known parameters that can be controlled during design, when the display state of a certain row of pixel rows 2 changes, the state of any other row of pixel rows 2 can be calculated by combining the scanning cycle of the driving circuit 3. Therefore, the display state of the first pixel row 21 can be accurately calculated and determined by combining the position of the first pixel row 21, the position of the second pixel row 22 and the scanning cycle of the driving circuit 3.

[0097] When the display state of the first pixel row 21 is off, the sensor 4 can directly perform sampling. When the display state of the first pixel row 21 is on, the time when the detection area 10 is off can be accurately calculated by combining the position of the first pixel row 21, the display state of the first pixel row 21 and the scanning cycle of the driving circuit 3, thereby determining the length of the delay time. The sensor 4 is sampled after the delay time interval, thereby avoiding interference with the sampling of the sensor 4 when the screen 1 is luminous, improving the single sampling accuracy of the sensor 4, thereby avoiding increasing the number of samples and the processing algorithm, and improving the system power consumption.

[0098] In some embodiments, the sensor 4 has a sampling cycle, and the sensor 4 performs intermittent sampling with the sampling cycle. The sampling work of the sensor 4 and the determination of the state of the pixel row 2 of the detection area 10 can be performed simultaneously. When it is determined that the sensor 4 is sampling, the pixel row 2 of the detection area 10 is in a lighted state, and the sensor 4 can abandon the current sampling result. When it is determined that the sensor 4 is sampling, the pixel row 2 of the detection area 10 is in an off state, and the sensor 4 can retain the current sampling result.
