[0029] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0030] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0031] The screen display control method provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0032] like Figure 1 As shown, an embodiment of the present application provides a screen display control method of an electronic device, which is executed by a central processing unit (CPU) of the electronic device, wherein the electronic device includes a screen module, an infrared sensor and an infrared transmitter, and the method includes:

[0033] Step 101: Acquire at least one target parameter of the content displayed in the target display area of ​​the screen module, wherein the at least one target parameter includes at least one of brightness and color scale.

[0034] Since infrared rays are invisible light with a wavelength of 940nm and contain high heat energy, when infrared rays pass through the screen, spots will appear on the screen. The spots will be different at different screen brightness or different display contents, especially at low brightness or when the screen display content is low grayscale color, the bright spots are more obvious. The main reasons include: photoelectric effect causing transistor leakage, photoelectric effect causing transistor gate to source voltage (Gate-Source Voltage, VGS) change, thermal effect causing screen electrical characteristics change, thermal effect causing screen material aging, etc. The embodiment of the present application obtains the target parameters of the content displayed by the infrared sensor in the projection area of ​​the screen module, so as to eliminate the bright spots displayed on the screen based on the color scale or brightness of the screen display content.

[0035] Step 102: When the parameter value of the target parameter is less than a first threshold value, controlling the infrared transmitter of the electronic device to emit infrared rays with a first infrared parameter;

[0036] When the parameter value of the target parameter is the first threshold, the infrared transmitter emits infrared rays with a second infrared parameter, and the infrared emission energy corresponding to the first infrared parameter is less than the infrared emission energy corresponding to the second infrared parameter.

[0037] In some embodiments of the present application, the infrared emitter is an infrared emitting lamp.

[0038] The values ​​of the first thresholds corresponding to the brightness and color scale may be the same or different.

[0039] The first threshold is a threshold determined through debugging. When the parameter value of the target parameter is the first threshold, the infrared transmitter emits infrared rays with the second infrared parameter, and when the infrared transmitter emits infrared rays with the second infrared parameter, there is no bright spot on the screen. Therefore, when the parameter value of the target parameter is less than the first threshold, in order to avoid bright spots on the screen, it is necessary to further adjust the infrared parameters so as to reduce the infrared emission energy of the infrared sensor.

[0040] Different electronic devices may correspond to different first thresholds.

[0041] In addition, when the parameter value of the above target parameter is greater than or equal to the first threshold, the infrared transmitter of the electronic device is controlled to emit infrared rays with a second infrared parameter.

[0042] When the parameter value of the screen target parameter is greater than or equal to the first threshold, it indicates that the display brightness of the screen is high brightness or the screen display content is high grayscale. In this case, bright spots are not easy to produce. Therefore, the infrared sensor of the electronic device is controlled to emit infrared rays with the second infrared parameter.

[0043] In an embodiment of the present application, at least one target parameter of the content displayed in the target display area of ​​the screen module is obtained, and the at least one target parameter includes at least one of brightness and color scale, and the target display area is the projection area of ​​the infrared sensor in the screen module; when the parameter value of the target parameter is less than the first threshold value, the infrared emitter is controlled to emit infrared rays with the first infrared parameter. Since when the parameter value of the target parameter is the first threshold value, the infrared emitter emits infrared rays with the second infrared parameter, and the infrared emission energy corresponding to the first infrared parameter is less than the infrared emission energy corresponding to the second infrared parameter, therefore, by controlling the infrared emitter to emit infrared rays with the first parameter, the infrared emission energy can be reduced, so that the infrared emission energy is reduced to the predetermined infrared emission energy, thereby avoiding the appearance of bright spots on the screen, thereby reducing the influence of bright spots on the screen display effect, and improving the screen display performance.

[0044] Optionally, the acquiring at least one target parameter of the content displayed in the target display area of ​​the screen module includes:

[0045] Acquiring the projection coordinates of the infrared sensor in the screen module of the electronic device;

[0046] Sending the projection coordinates to a screen module of the electronic device;

[0047] Acquire display content of a target display area sent by the screen module, wherein the target display area is determined according to the projection coordinates;

[0048] At least one target parameter of the displayed content is determined.

[0049] like Figure 2As shown, the electronic device of the embodiment of the present application includes a CPU, a screen module and an infrared sensor. Among them, the screen module communicates with the CPU through the Mobile Industry Processor Interface (MIPI) protocol to transmit screen-related information. The infrared sensor communicates with the CPU through the Inter-Integrated Circuit (IIC) protocol, and infrared data and register information are transmitted between the two. In the screen module, the main function of the storage IC is to store image display information and register data, and the main function of the display driver IC (DDIC) is the driver IC of the screen module, image decoding, etc. In the CPU, memory 1 is used to store infrared parameters, memory 2 is used to store the projection coordinates of the infrared sensor on the screen, the screen driver module is mainly responsible for communicating with the screen module, and the sensor driver module is mainly responsible for communicating with the infrared sensor. The framework layer coordinates the call and data processing of the screen, sensor, and memory module.

[0050] In some embodiments of the present application, the CPU calls the projection coordinates of the infrared sensor on the screen from the memory 2, and sends the projection coordinates to the screen module through the screen driver module. In the screen module, the DDIC receives the projection coordinates, obtains the display content of the target display area corresponding to the projection coordinates in the storage IC of the screen, and returns it to the CPU. In the CPU, the screen driver module transmits the display content of the target display area to the framework layer, and the framework layer obtains the color scale of the display content of the target display area through algorithm analysis.

[0051] Since the bright spot generated on the screen is located at the projection position of the infrared sensor on the screen, by obtaining the color scale of the screen display content at the projection position of the infrared sensor on the screen, the infrared emission energy that needs to be reduced at the projection position can be accurately determined based on the color scale, thereby more effectively eliminating the infrared bright spot on the screen.

[0052] Optionally, as an implementation manner, the first infrared parameter includes at least one of the following:

[0053] The current of the infrared transmitter;

[0054] Voltage of infrared transmitter;

[0055] The power of the infrared transmitter;

[0056] Duty cycle of the infrared transmitter.

[0057] The above duty cycle refers to the proportion of the power-on time to the total time in one pulse cycle.

[0058] In some embodiments of the present application, the infrared emission energy of the infrared sensor can be reduced by reducing the current of the infrared emitter, reducing the voltage of the infrared emitter, reducing the power of the infrared emitter, and reducing the duty cycle. In this embodiment, the emission frequency, pulse width, and pulse interval of the infrared pulses emitted by the infrared emitter in the emission cycle are fixed.

[0059] Of course, the above-mentioned first infrared parameter may also include other infrared parameters that can reduce the infrared emission energy, which will not be described here.

[0060] Optionally, as another implementation manner, the first infrared parameter includes at least one of the following:

[0061] at least two pulse widths of infrared pulses emitted by the infrared transmitter within a transmission cycle;

[0062] at least two pulse intervals of infrared pulses emitted by the infrared transmitter within a transmission cycle;

[0063] At least two pulse emission frequencies of infrared pulses emitted within an emission period of the infrared emitter.

[0064] In the embodiment of the present application, the pulse width, pulse interval, and pulse emission frequency of the infrared sensor are all adjustable. According to the principle of the generation of infrared bright spots on the screen, it can be known that the infrared light energy causes the material properties inside the screen to produce photoelectric or thermal effects. In the related art, the emission timing and reception timing of infrared rays are as follows: Figure 3 As shown, within one cycle, the infrared transmitter emits a relatively large pulse or multiple fixed-width pulses, which causes the infrared energy to accumulate in the upper screen area and is difficult to release quickly, thus forming a bright spot.

[0065] In some embodiments of the present application, the infrared pulses are modulated by controlling the on and off time of the infrared emitter to reduce the energy gathered by the infrared emitter on the screen per unit time, thereby achieving the purpose of eliminating the infrared bright spots on the screen. For example, by modulating the infrared emission energy within a cycle, the screen's refresh characteristics are used to reduce the impact of infrared on the screen. In the embodiments of the present application, the infrared emission timing and reception timing are as follows: Figure 4 shown. Figure 4 In the example, the screen refresh signal is the frame refresh signal of the screen. Infrared emission refers to the timing of the infrared emitter emitting energy. One cycle mainly includes the emission cycle and the waiting emission cycle. H 0.T H 1. T H X, …, T H N represents the pulse width of the infrared pulse in the emission cycle, T L 0.T L 1. T L X, …, TL N represents the pulse interval between infrared pulses, T H X and T L X can be modified through the register to modify the corresponding value, that is, the pulse width and pulse interval in the embodiment of the present application can be adjusted. When infrared bright spots appear on the screen, by adjusting T H X and T L X gives infrared energy time to dissipate, avoiding the bright spots on the screen caused by emitting a large amount of energy at one time, and using the method of "small amounts, multiple times, and time division multiplexing" to make the bright spots disappear. In the receiving sequence, it mainly includes the integration period and the data processing period. The reception of infrared rays requires turning on the integrator before the infrared transmitter emits energy, and turning off the integration after the emission cycle is completed. This method is used to receive the energy of multiple infrared pulses and improve the signal-to-noise ratio. At the same time, after the emission cycle is completed, the screen refresh rate is used to reset the corresponding circuit of the screen to release the energy accumulated on the screen by the infrared.

[0066] By splitting the wide pulse of infrared light into multiple adjustable narrow pulses, the infrared pulses are modulated and the energy gathered by the infrared light on the screen per unit time is reduced, thereby achieving the purpose of eliminating the infrared bright spots on the screen.

[0067] Optionally, obtaining at least one target parameter includes:

[0068] When the electronic device is not in a call mode, at least one target parameter is acquired.

[0069] In some embodiments of the present application, after the electronic device is turned on, it is first determined whether the electronic device is in a call mode, and when the electronic device is not in a call mode, at least one target parameter is obtained. Since the requirements for infrared emission energy are different in the call mode and the non-call mode, in the call mode, the infrared emitted by the infrared transmitter can prevent the user from accidentally touching the screen when answering a call. For example, when the user holds the mobile phone close to the ear when answering a call, the infrared sensor will recognize that the mobile phone is close to an object (such as the ear), thereby triggering the "intelligent body sensing" function, and the screen will automatically turn off to prevent the user from accidentally touching the screen when answering a call. In the call mode, the user does not pay much attention to the display content on the screen. Therefore, in the call mode, the infrared sensor needs to maintain a high infrared emission energy to ensure call performance. In the non-call mode, the user will pay more attention to the display content on the screen. Therefore, in the non-call mode, it is more necessary to eliminate the infrared bright spots on the screen based on the above target parameters.

[0070] Optionally, the method of the embodiment of the present application further includes:

[0071] When the electronic device is in a call mode, controlling the infrared transmitter to emit infrared rays with a third infrared parameter;

[0072] Among them, the infrared emission energy corresponding to the third infrared parameter is greater than the infrared emission energy corresponding to the second infrared parameter.

[0073] Here, when the electronic device is in a call mode, the user's call performance can be effectively guaranteed by controlling the infrared transmitter to emit infrared rays with the third infrared parameter.

[0074] The screen display control method of the present application is described in detail below in conjunction with an embodiment. In this embodiment, the target parameter is a color scale as an example for description.

[0075] like Figure 5 As shown, the screen display control method includes:

[0076] Step 1: Initialize the infrared sensor and screen driver module.

[0077] Step 2: Determine whether the device is in call mode.

[0078] For example, the framework layer determines whether the electronic device is in a call mode.

[0079] Step 301: When the electronic device is in a call mode, a first state is sent to a sensor driving module.

[0080] The framework layer sends the first state to the sensor driving module.

[0081] Step 401: The sensor driving module notifies the infrared sensor to drive the infrared transmitter to emit infrared rays with a third infrared parameter.

[0082] For example, the sensor driving module calls the third infrared parameter from the memory 1 .

[0083] Here, the infrared sensor drives the infrared emitter to emit infrared rays with the third infrared parameter to increase the infrared emission energy and ensure the user's usage experience.

[0084] Step 302: When the electronic device is not in a call mode, obtain the projection coordinates of the infrared sensor on the screen.

[0085] For example, the framework layer calls the projection coordinates of the infrared sensor on the screen from the memory 2 .

[0086] Step 402: Obtain the color scale of the screen display content of the target display area corresponding to the projection coordinates.

[0087] The framework layer sends the projection coordinates to the screen module through the screen driver module. After receiving the projection coordinates, the DDIC in the screen module obtains the screen display content of the target display area corresponding to the projection coordinates from the screen storage IC and sends it back to the CPU. The screen driver module in the CPU passes the obtained screen display content to the framework layer, and the framework layer obtains the color level through algorithm analysis.

[0088] Step 5: Determine whether the color level is less than a first threshold.

[0089] Step 601: When the color level is less than the first threshold, a second state is sent to a sensor driving module.

[0090] Step 701: The sensor driving module notifies the infrared sensor to drive the infrared transmitter to emit infrared rays with a first infrared parameter.

[0091] For example, the sensor driving module calls the first infrared parameter from the memory 1 .

[0092] Here, the infrared transmitter is driven by the infrared sensor to emit infrared rays with the first infrared parameter to reduce the infrared emission energy.

[0093] Step 602: When the color level is greater than or equal to the first threshold, send a third state to the sensor driving module.

[0094] Step 702: The sensor driving module notifies the infrared sensor to drive the infrared transmitter to emit infrared rays with the second infrared parameter.

[0095] For example, the sensor driving module calls the second infrared parameter from the memory 1 .

[0096] Here, the infrared sensor drives the infrared emitter to emit infrared rays with the first infrared parameter to keep the infrared emission energy unchanged.

[0097] In an embodiment of the present application, different infrared parameters are called based on the current working mode of the electronic device, the screen display brightness, or the color level of the screen display content. When the electronic device is in a call mode, the infrared emission energy is increased to ensure the call performance. When the electronic device is not in a call mode and the parameter value of the target parameter is less than a first threshold, the infrared emission energy is reduced to avoid bright spots on the screen.

[0098] like Figure 6 As shown, an embodiment of the present application provides an electronic device, including:

[0099] A screen module, which includes a screen 604 and a screen foam 605. The screen can also be described as a glass cover;

[0100] An infrared sensor 602 and an infrared emitter 601, wherein the infrared sensor 602 and the infrared emitter 601 are respectively arranged on a printed circuit board (PCB) 603 of the electronic device, wherein the infrared ray emitted by the infrared emitter 601 passes through the screen module, and the infrared sensor receives the infrared ray that passes through the screen module after being reflected by an obstruction;

[0101] A central processing unit, wherein the central processing unit is used to obtain at least one target parameter of the content displayed in the target display area of ​​the screen module, wherein the at least one target parameter includes at least one of brightness and color scale, and the target display area is the projection area of ​​the infrared sensor in the screen module; when the parameter value of the target parameter is less than a first threshold value, the infrared emitter is controlled to emit infrared rays with a first infrared parameter.

[0102] The central processing unit is disposed on a printed circuit board 603 .

[0103] In the embodiment of the present application, by controlling the infrared emitter to emit infrared rays with a first parameter, the infrared emission energy can be reduced so that the infrared emission energy is reduced to a predetermined infrared emission energy, thereby avoiding the appearance of bright spots on the screen, thereby reducing the impact of the bright spots on the screen display effect and improving the screen display performance.

[0104] Alternatively, if Figure 6 As shown, the electronic device of the embodiment of the present application further includes:

[0105] The first lens 606 is disposed between the screen module and the infrared emitter 601 , and is used for dispersing the infrared rays emitted by the infrared emitter 601 .

[0106] As an implementation, the first lens 606 is a convex lens.

[0107] The infrared emission energy of the infrared emitter is dispersed on the screen through the first lens, reducing the infrared energy per unit area, thereby avoiding the concentration of infrared energy and achieving the purpose of eliminating infrared bright spots.

[0108] Optionally, the electronic device of the embodiment of the present application further includes:

[0109] The second lens 607 is disposed between the screen module and the infrared sensor 602 , and is used for focusing infrared rays.

[0110] As an implementation manner, the second lens is a concave lens.

[0111] The infrared rays reflected by the obstruction 611 are concentrated by the second lens to improve the infrared performance.

[0112] The electronic device also includes: a middle frame 608 , light-shielding foam 609 , and a pad 610 .

[0113] Compared with the existing electronic devices, the electronic device of the embodiment of the present application has a first lens and a second lens. By adding the first lens, the infrared rays emitted by the infrared emitter are scattered and distributed on the screen, thereby reducing the infrared energy per unit area of ​​the screen. After the emitted infrared rays are reflected by external obstacles, the second lens is used to focus the light at the receiving hole, so as to achieve the purpose of eliminating bright spots on the screen while ensuring the infrared performance.

[0114] It should be noted that the screen display control method provided in the embodiment of the present application can be executed by a screen display control device or a control module in the screen display control device for executing the screen display control method. In the embodiment of the present application, the screen display control device provided in the embodiment of the present application is described by taking the screen display control method executed by the screen display control device as an example.

[0115] like Figure 7 As shown, an embodiment of the present application provides a screen display control device 700 of an electronic device, wherein the electronic device includes a screen module, an infrared sensor and an infrared transmitter, and the device includes:

[0116] A first processing module 701 is used to obtain at least one target parameter of the content displayed in the target display area of ​​the screen module, wherein the at least one target parameter includes at least one of brightness and color scale, and the target display area is the projection area of ​​the infrared sensor in the screen module;

[0117] The second processing module 702 is used to control the infrared transmitter to emit infrared rays with a first infrared parameter when the parameter value of the target parameter is less than a first threshold value;

[0118] When the parameter value of the target parameter is the first threshold, the infrared transmitter emits infrared rays with a second infrared parameter, and the infrared emission energy corresponding to the first infrared parameter is less than the infrared emission energy corresponding to the second infrared parameter.

[0119] Optionally, the first processing module is used to:

[0120] Acquiring the projection coordinates of the infrared sensor in the screen module of the electronic device;

[0121] Sending the projection coordinates to a screen module of the electronic device;

[0122] Acquire display content of a target display area sent by the screen module, wherein the target display area is determined according to the projection coordinates;

[0123] At least one target parameter of the displayed content is determined.

[0124] Optionally, the first infrared parameter includes at least one of the following:

[0125] The current of the infrared transmitter;

[0126] Voltage of infrared transmitter;

[0127] The power of the infrared transmitter;

[0128] Duty cycle of the infrared transmitter.

[0129] Optionally, the first infrared parameter includes at least one of the following:

[0130] at least two pulse widths of infrared pulses emitted by the infrared transmitter within a transmission cycle;

[0131] at least two pulse intervals of infrared pulses emitted by the infrared transmitter within a transmission cycle;

[0132] The pulse transmission frequency of the infrared pulses emitted within the transmission cycle of the infrared transmitter.

[0133] Optionally, the first processing module is used to:

[0134] When the electronic device is not in a call mode, at least one target parameter of the content displayed in the target display area of ​​the screen module is obtained.

[0136] A third processing module, configured to control the infrared transmitter to transmit infrared rays with a third infrared parameter when the electronic device is in a call mode;

[0137] Among them, the infrared emission energy corresponding to the third infrared parameter is greater than the infrared emission energy corresponding to the second infrared parameter.

[0138] The device of the embodiment of the present application obtains at least one target parameter of the content displayed in the target display area of ​​the screen module, the at least one target parameter includes at least one of brightness and color scale, and the target display area is the projection area of ​​the infrared sensor in the screen module; when the parameter value of the target parameter is less than the first threshold value, the infrared emitter is controlled to emit infrared rays with the first infrared parameter. Since when the parameter value of the target parameter is the first threshold value, the infrared emitter emits infrared rays with the second infrared parameter, and the infrared emission energy corresponding to the first infrared parameter is less than the infrared emission energy corresponding to the second infrared parameter, therefore, by controlling the infrared emitter to emit infrared rays with the first parameter, the infrared emission energy can be reduced, so that the infrared emission energy is reduced to the predetermined infrared emission energy, thereby avoiding the appearance of bright spots on the screen, thereby reducing the influence of bright spots on the screen display effect, and improving the screen display performance.
