Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a display screen control method, system, device, and storage medium. Background Art

[0002] Light emitting diode (LED) displays have been widely used due to their advantages such as high brightness, wide color gamut, and seamless splicing. LED displays include one or more LED modules, which are usually composed of a base shell, a light board, and a mask. The light board includes multiple lamp beads. When working, the LED module converts electrical energy into light energy to display images. However, the LED module generates heat during operation, and the heat dissipation rate in the edge area of ​​the base shell is usually faster than that in the middle area, which results in a larger temperature difference between the edge area and the middle area of ​​the lamp board. The brightness of the LED lamp beads will change with changes in temperature. The large temperature difference will cause uneven brightness in different areas of the LED module, resulting in poor display effect. Summary of the Invention

[0045] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0046] It should be understood that the “multiple” mentioned in this application refers to two or more. In the description of this application, unless otherwise specified, “ / ” means or, for example, A / B can mean A or B; “and / or” in this article is merely a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solution of this application, words such as “first” and “second” are used to distinguish between identical or similar items with basically the same functions and effects. Those skilled in the art can understand that words such as “first” and “second” do not limit the quantity and execution order, and words such as “first” and “second” do not necessarily limit them to be different.

[0047] The phrases "one embodiment" or "some embodiments" described in this application mean that the specific features, structures, or characteristics described in the embodiment are included in one or more embodiments of the application. Thus, the phrases "in one embodiment," "in some embodiments," "in some other embodiments," and "in some other embodiments" that appear in different places in this application do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. In addition, the terms "including," "comprising," "having," and their variations all mean "including but not limited to," unless otherwise specifically emphasized.

[0048] The application scenarios of the embodiments of the present application are described below.

[0049] As a self-luminous display product, LED display screen has the advantages of high brightness, wide color gamut, and seamless splicing, but it also has problems such as high heat generation.

[0050] The LED display screen includes multiple LED modules. The LED module is generally composed of a base shell, a lamp board (including but not limited to a printed circuit board assembly (PCBA)), a mask, etc. The base shell and mask of the LED module are made of materials such as die-cast aluminum and a magnesium base shell, which makes the heat dissipation capacity of the back of the lamp board better. However, the metal base shell itself also has certain shortcomings, that is, the heat dissipation at the edge of the base shell is faster than the middle part of the base shell, which makes the edge area of ​​the lamp board dissipate heat faster than the middle area, thereby generating a temperature difference. The brightness of the LED lamp beads will change with the change of temperature. When the temperature difference is large, the brightness of the lamp beads on the LED module will be inconsistent, resulting in a "white border" phenomenon. Generally, there are two reasons for this phenomenon:

[0051] 1. There are gaps between the metal chassis, and the edge heat dissipation capacity is stronger. The edge area of ​​the light panel is in close contact with the metal chassis, which causes the heat in the edge area of ​​the light panel to be quickly transferred to the edge of the metal chassis for heat dissipation, resulting in a temperature difference between the edge area and the middle area of ​​the light panel.

[0052] 2. The brightness of LED lamp beads is greatly affected by temperature. The luminous efficiency of LED lamp beads decreases as the temperature rises. When the temperature difference reaches a certain level, the brightness of the edge area and the middle area of ​​the LED module will be significantly inconsistent, which will be clearly noticed by the human eye.

[0053] Based on this, how to solve this problem has become a technical problem in the industry.

[0054] In the related art, the lamp beads in the LED module are aged in full white for a certain period of time to form a temperature difference between the edge area and the central area of ​​the light board. After that, optical correction is performed to make the brightness of the lamp beads in the edge area and the central area of ​​the light board consistent. However, this method can only solve the problem of inconsistent brightness when there is a fixed temperature difference between the edge area and the central area of ​​the light board. In actual applications, different climates, different seasons, and different weather conditions may cause the temperature difference between the edge area and the central area of ​​the light board to vary. When the temperature difference is inconsistent with this fixed temperature difference, the LED module will still have the problem of uneven brightness in different areas, and may even aggravate the severity of the problem.

[0055] To this end, an embodiment of the present application provides a display screen control method. In this method, the environmental status information of the display screen is periodically obtained. Each time the environmental status information of the display screen is obtained, the coefficient set identifier is determined from the preset correspondence according to the environmental status information, and the brightness of the n lamp beads in each display module in the display screen is controlled according to the n sets of coefficients in the target coefficient set identified by the target coefficient set identifier. The preset correspondence includes coefficient set identifiers corresponding to different environmental states, so that the corresponding coefficient set identifier can be accurately switched to under different environmental states to enable the display screen to display normally. In this way, the coefficient to be applied can be adaptively adjusted according to the current environmental state, so that the display screen can maintain a high brightness consistency under different environmental states, thereby improving the display effect of the display screen. Moreover, since the environmental status information of the display screen is periodically obtained, the brightness of the display screen can be adjusted in time when the environmental state changes, thereby improving the display stability of the display screen.

[0056] The display system provided in the embodiment of the present application is described below.

[0057] Figure 1 This is a schematic diagram of the structure of a display system provided by an embodiment of the present application. Figure 1The display system 10 may include a first control module 101, m second control modules 102 and m groups of display modules 103, wherein the m second control modules 102 correspond to the m groups of display modules 103 one by one, and m is a positive integer.

[0058] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation of the display system 10 , and the display system 10 may include more or fewer components than shown, or combine certain components, or adopt a different arrangement of components.

[0059] The first control module 101 can communicate with each of the m second control modules 102 via a wired or wireless connection. Alternatively, the m second control modules 102 can be cascaded; the first control module 101 can communicate with the first of the m second control modules 102 via a wired or wireless connection, and can communicate with each of the remaining second control modules 102 via the first second control module 102. For example, the first control module 101 can also be called a main controller or a sending card, etc., which is not limited in this embodiment of the present application.

[0060] Any one of the m second control modules 102 can communicate with a corresponding one of the m groups of display modules 103 via a wired or wireless connection. For example, the second control module 102 can also be referred to as a control board or a receiving card, etc., which is not limited in this embodiment of the present application.

[0061] All display modules 103 in the m groups of display modules 103 can constitute a screen of a display screen.

[0062] All display modules 103 in the m groups of display modules 103 can be identical display modules, such as LED modules. The number of display modules in any two groups of display modules 103 in the m groups of display modules 103 can be the same or different. Each display module 103 in the m groups of display modules 103 can include n lamp beads, where n is an integer greater than or equal to 2.

[0063] The first control module 101 is configured to obtain environmental status information of the display screen, determine a coefficient set identifier from a preset correspondence according to the environmental status information, and send the coefficient set identifier to the second control module 102 .

[0064] The environmental status information is information about the state of the environment in which the display screen is located. For example, the environmental status information may include one or more of the following: temperature information of the display screen's external environment (i.e., the first temperature information described below), light intensity information, time information, and temperature information of the display screen's internal environment (i.e., the second temperature information described below). This is not limited in the present embodiment. In this way, the display screen's environment can be more accurately assessed, which in turn facilitates subsequent accurate control of the brightness of the lamp beads in the display screen.

[0065] Alternatively, as Figure 2 As shown, the display system 10 may include a temperature sensor and / or a light sensor, and environmental status information may be collected through the temperature sensor and / or the light sensor.

[0066] For example, the first control module 101 may obtain the first temperature information through a first temperature sensor. For example, the first temperature sensor may be disposed on the front of a display screen, etc., which is not limited in the embodiment of the present application.

[0067] For another example, the first control module 101 may obtain light intensity information through a light sensor. For example, the light sensor may be disposed on the front of a display screen, etc., which is not limited in this embodiment of the present application.

[0068] For another example, the first control module 101 may obtain the second temperature information through a second temperature sensor. For example, the second temperature sensor may be disposed on the surface of the second control module 102 or the surface of the display module 103, etc., which is not limited in this embodiment of the present application.

[0069] The first control module 101 may include a preset correspondence. The preset correspondence is a correspondence between the environmental state information and the coefficient set identifier. The preset correspondence may be pre-set. For example, Figure 2 As shown, the display system 10 may further include a computer device 104. The computer device 104 may perform thermal simulation experiments to obtain a correspondence between environmental state information and coefficient set identifiers. For example, the computer device 104 may be a mobile phone, a computer, or the like. Optionally, the computer device 104 may be installed with control software for controlling the display screen.

[0070] The coefficients in the coefficient set identified by the coefficient set identifier are used to control the brightness of n lamp beads in the display module 103. For example, the coefficient set identifier can be a storage area identifier corresponding to the coefficient set identified by the coefficient set identifier. The storage area identifier corresponding to the coefficient set is used to identify the storage area storing the coefficient set.

[0071] In some cases, the first control module 101 may be integrated into a display screen, or the first control module 101 may exist as an independent component, which is not limited in the embodiments of the present application.

[0072] After receiving the coefficient set identifier sent by the first control module 101, any one of the m second control modules 102 can generate a control signal based on the coefficient set identified by the coefficient set identifier, and output the control signal to each display module 103 in the corresponding group of display modules 103 to control the brightness of the lamp beads in each display module 103. For example, the control signal can be a pulse width modulation (PWM) signal.

[0073] In some embodiments, each second control module 102 may store the coefficient set identified by each coefficient set identifier in a preset correspondence. Alternatively, if the coefficient set identifier is a storage area identifier, the second control module 102 may read the coefficient set stored in the storage area identified by the storage area identifier (i.e., the coefficient set identifier) ​​sent by the first control module 101. Alternatively, if the coefficient set identifier is not a storage area identifier, the second control module 102 may include a correspondence between the coefficient set identifier and the coefficient set, and the second control module 102 may obtain the coefficient set corresponding to the coefficient set identifier sent by the first control module 101 from the correspondence.

[0074] In other embodiments, the coefficient set identified by each coefficient set identifier in the preset correspondence relationship may not be stored in the second control module 102, but may be stored in the display module 103, such as in the first display module 103 in a group of display modules 103 corresponding to each second control module 102. In the case where the coefficient set identifier is a storage area identifier, the second control module 102 may obtain from the display module 103 the coefficient set stored in the storage area identified by the storage area identifier (i.e., the coefficient set identifier) ​​sent by the first control module 101. Alternatively, in the case where the coefficient set identifier is not a storage area identifier, the display module 103 may include a correspondence relationship between the coefficient set identifier and the coefficient set, and the second control module 102 may obtain from the correspondence relationship the coefficient set corresponding to the coefficient set identifier sent by the first control module 101.

[0075] It should be noted that, when the coefficient set identifier is a storage area identifier, the storage area identifiers of the storage areas for storing the same coefficient set in each second control module 102 or each display module 103 for storing the coefficient set are the same.

[0076] For example, any one of the m second control modules 102 can be integrated into the display screen, or any one of the m second control modules 102 can exist as an independent component, which is not limited in the embodiment of the present application.

[0077] For example, Figure 3 1 is a structural diagram of a second control module 102 provided in an embodiment of the present application. Figure 3 As shown, the second control module 102 may include a first control unit 1021 , a storage unit 1022 and a second control unit 1023 .

[0078] The first control unit 1021 can communicate with the storage unit 1022 via a wired connection or a wireless connection. For example, the first control unit 1021 can be a microcontroller unit (MCU) or a central processing unit (CPU), etc., which is not limited in this embodiment of the present application. For example, the storage unit 1022 can also be called a memory.

[0079] The first control unit 1021 can communicate with the second control unit 1023 via a wired connection or a wireless connection. For example, the second control unit 1023 can be a field-programmable gate array (FPGA), etc., which is not limited in this embodiment of the present application.

[0080] In some implementations, the storage unit 1022 is configured to store the coefficient set identified by each coefficient set identifier in the preset correspondence. Figure 3 As shown, the one or more coefficient sets may be stored in a coefficient set storage area in the storage unit 1022. The coefficient set storage area includes one or more storage areas, each of which is used to store a coefficient set. In other embodiments, the coefficient set identified by each coefficient set identifier in the preset correspondence may not be stored in the storage unit 1022, but may be stored in the display module 103.

[0081] The first control unit 1021 is configured to receive the coefficient set identifier sent by the first control module 101 , obtain the coefficient set from the storage unit 1022 or the display module 103 according to the coefficient set identifier, and send the coefficient set to the second control unit 1023 .

[0082] The second control unit 1022 is used to receive the coefficient set sent by the second control unit 1023, generate a control signal according to the coefficient set, and send the control signal to each display module 103 in a corresponding group of display modules 103 to control the brightness of the lamp beads in each display module 103.

[0083] Those skilled in the art will understand that the above Figure 3 The structure shown does not constitute a limitation on the second control module 102 , and the second control module 102 may include more or fewer components than shown, or combine certain components, or adopt a different arrangement of components.

[0084] Optionally, any one of the n lamp beads in the display module 103 may include one or more primary color chips, each of which is used to emit light of a specific color. For example, when there is only one primary color chip in a lamp bead, the lamp bead can be called a single-color lamp bead; when there are multiple primary color chips in a lamp bead, the lamp bead can be called a multi-color lamp bead or a full-color lamp bead. For example, Figure 4 As shown, the full-color lamp bead may include a red primary color chip, a green primary color chip and a blue primary color chip. The red primary color chip is used to emit red light, the green primary color chip is used to emit green light, and the blue primary color chip is used to emit blue light.

[0085] The brightness of a lamp bead can be controlled by one or more control signals (hereinafter referred to as a set of control signals). Optionally, if the lamp bead includes a primary color chip, the set of control signals used to control the lamp bead may include a single control signal, which is used to control the brightness of the primary color chip. If the lamp bead includes multiple primary color chips, the set of control signals used to control the lamp bead may include multiple control signals, which are used to control the brightness of the multiple primary color chips one by one.

[0086] In some embodiments, the display system 10 may include multiple display screens, each of which may include m groups of display modules 103. In this case, the display system 10 may include multiple first control modules 101 and multiple groups of second control modules 102. The multiple first control modules 101, the multiple groups of second control modules 102, and the multiple display screens may correspond one to one. Optionally, each of the multiple first control modules 101 may communicate with the same computer device 104.

[0087] Each of the multiple groups of second control modules 102 includes m second control modules 102. The number of second control modules 102 in any two of the multiple groups of second control modules 102 (i.e., the number of display modules 103 groups in any two of the multiple display screens, i.e., m) can be the same or different, and this is not limited in this embodiment of the present application. For example, one display screen includes 8 groups of display modules 103, each corresponding to 8 second control modules 102; another display screen includes 9 groups of display modules 103, each corresponding to 9 second control modules 102.

[0088] Optionally, the multiple display screens may exist independently, or each of the multiple display screens may serve as a sub-screen and become part of a larger display screen, which is not limited in the embodiments of the present application.

[0089] Optionally, the orientations of any two display screens among the multiple display screens may be the same or different.

[0090] Optionally, the environmental status information referenced when controlling different display screens can be different. For example, the display system 10 includes two display screens, one facing the sun and the other facing away from the sun. In this case, when controlling the display screen facing the sun, the light intensity information can be referenced, while when controlling the display screen facing away from the sun, the temperature information (including but not limited to the first temperature information and / or the second temperature information) can be referenced.

[0091] In this case, each second control module 102 in a group of second control modules 102 corresponding to the Xiangyang display screen can store a coefficient set corresponding to each of one or more illumination intensity information. The preset correspondence in a first control module 101 corresponding to the Xiangyang display screen can be a correspondence between illumination intensity information and a system set identifier.

[0092] Each second control module 102 in a group of second control modules 102 corresponding to the back-yang display screen can store a coefficient set corresponding to each temperature information in one or more temperature information. The preset correspondence in a first control module 101 corresponding to the back-yang display screen can be a correspondence between temperature information and a system set identifier.

[0093] In this way, appropriate environmental status information can be selected to control the corresponding display screen according to factors affecting the environment of the display screen, such as the orientation and position of the different display screens, thereby helping to improve the accuracy of controlling the display screen.

[0094] The following is a detailed explanation of the display screen control method provided in an embodiment of the present application. The display screen control method can be executed by a display screen control system. The display screen control system can include the first control module 101 and the second control module 102 described above, and optionally, can also include a computer device 104.

[0095] In some embodiments, the display screen control system may first obtain a preset correspondence (i.e., a correspondence between environmental state information and a coefficient set) before controlling the brightness of each lamp in each display module in the display screen. For example, the preset correspondence may be obtained by the computer device 104.

[0096] The following is an exemplary description of the process of obtaining the preset corresponding relationship, which may include the following steps A to C.

[0097] Step A: The display screen control system constructs a display module model, which is a three-dimensional model of the display module.

[0098] The display module model may include n lamp bead models. The lamp bead model is a three-dimensional model of the lamp bead.

[0099] Step B: For any one of the multiple preset environmental state information, the display screen control system performs thermal simulation on the display module model according to the preset environmental state information to obtain the temperature of each of the multiple areas in the display module model; determines the brightness of each area according to the temperature of each area in the multiple areas; and determines the coefficient set corresponding to the preset environmental state information according to the brightness of each area in the multiple areas.

[0100] The preset environmental state information can be preset. For example, when the preset environmental state information includes first temperature information, the plurality of preset environmental state information can include at least two of 0 degrees Celsius (°C), 10°C, 20°C, etc. For another example, when the preset environmental state information includes light intensity, the plurality of preset environmental state information can include 0 watts / square meter (W / m 2 ), 300W / m 2 , 600W / m 2 For another example, if the preset environmental status information includes time information, the multiple preset environmental status information may include at least two of 8 o'clock, 12 o'clock, 15 o'clock, etc. For another example, if the preset environmental status information includes second temperature information, the multiple preset environmental status information may include at least two of 40°C, 50°C, 60°C, etc.

[0101] The multiple areas in the display module model can be pre-set. For example, the multiple areas can include at least two of an edge area, a near-edge area, a middle area, etc., which is not limited in this embodiment of the present application.

[0102] Thermal simulation of the display module model refers to simulating the temperature distribution, heat transfer and heat dissipation performance of the display module under working conditions through computer software.

[0103] The brightness of any area in the display module model refers to the brightness of the lamp beads in that area.

[0104] Because the brightness of the lamp beads is temperature-dependent, the brightness of each of the multiple regions can be determined based on the temperature of each region of the display module model under the environment corresponding to the preset environmental state information obtained through thermal simulation. Once the brightness of each region is determined, the brightness differences between the multiple regions can be determined. A coefficient set can then be determined based on the brightness differences between the multiple regions. By adjusting the brightness of the lamp beads using this coefficient set, the brightness differences between the multiple regions can be reduced, thereby improving the brightness consistency of the multiple regions.

[0105] By testing the temperature of each of the multiple areas in the display module model under different preset environmental state information and determining the coefficient set corresponding to each preset environmental state information, the display screen can be adapted to more scenario applications.

[0106] For example, Figure 5 As shown, the display screen control system can perform thermal simulation on the display module model when the external environment temperature is 0°C and 20°C, and obtain the temperature of each area in the multiple areas of the display module model. Figure 5 The temperature of a printed circuit board (PCB) is used as an example. When the external ambient temperature is 0°C, Figure 5 As shown in (a) of FIG, the temperature of the middle area of ​​the PCB is 16.3°C, the temperature of the edge area is 0.5°C, and the temperature difference between the middle area and the edge area is 15.8°C. When the external ambient temperature is 20°C, Figure 5 As shown in (b), the temperature of the middle area of ​​the PCB is 33.9°C, the temperature of the edge area is 18.8°C, and the temperature difference between the middle area and the edge area is 15.1°C.

[0107] For example, Figure 6 As shown in the figure, the display control system can respectively control the display module model under the external environment temperature of 30℃ and the light intensity of 0W / m 2 and 600W / m 2The thermal simulation is performed to obtain the temperature of each area in the multiple areas of the display module model. Figure 6 The temperature of PCB is used as an example. When the external environment temperature is 30℃ and the light intensity is 0W / m 2 When, such as Figure 6 As shown in (a), the temperature of the middle area of ​​the PCB is 60.1°C and the temperature of the edge area is 46.8°C. The temperature difference between the middle area and the edge area is 13.2°C. When the external environment temperature is 30°C and the light intensity is 600W / m 2 When, such as Figure 6 As shown in (b), the temperature of the middle area of ​​the PCB is 82.4°C, the temperature of the edge area is 60.6°C, and the temperature difference between the middle area and the edge area is 21.7°C.

[0108] For example, Figure 7 As shown in the figure, the display control system can respectively control the display module model under the external environment temperature of 40℃ and the light intensity of 0W / m 2 and 600W / m 2 The thermal simulation is performed to obtain the temperature of each area in the multiple areas of the display module model. Figure 7 The temperature of PCB is used as an example. When the external environment temperature is 40℃ and the light intensity is 0W / m 2 When, such as Figure 7 As shown in (a), the temperature of the middle area of ​​the PCB is 68.8°C, the temperature of the edge area is 56.0°C, and the temperature difference between the middle area and the edge area is 12.7°C. When the external environment temperature is 40°C and the light intensity is 600W / m 2 When, such as Figure 7 As shown in (b), the temperature of the middle area of ​​the PCB is 95.3°C, the temperature of the edge area is 73.7°C, and the temperature difference between the middle area and the edge area is 21.6°C.

[0109] In summary, if Figure 8 As shown, in the absence of solar radiation, as the ambient temperature continues to rise, the maximum temperature difference between multiple areas in the display module model decreases linearly. In the presence of solar radiation, as the ambient temperature continues to rise, the maximum temperature difference between multiple areas in the display module model changes nonlinearly.

[0110] The embodiments of this application are only Figure 5 、 Figure 6 、 Figure 7 、 Figure 8Taking the example of FIG1 as an example, the temperature difference between multiple areas in the display module model under different external ambient temperatures and different light intensities is illustrated. In actual applications, the display module model can also be thermally simulated under other conditions (such as different times and / or different internal ambient temperatures, etc.) to obtain more temperature data for subsequent reference.

[0111] In some embodiments, the operation of the display screen control system determining the brightness of each area according to the temperature of each area among the multiple areas may be: determining the brightness of each area according to the temperature of each area among the multiple areas and a preset function.

[0112] The preset function is used to describe the relationship between the lamp bead temperature and the lamp bead brightness. The preset function can be pre-set. For any of the multiple areas, the display control system substitutes the temperature of the area into the preset function to obtain the brightness of the area.

[0113] For example, Figure 9 As shown, the lamp bead may include multiple primary color chips. Taking the brightness of the lamp bead at 25°C as a reference, the relative light intensity (i.e., brightness) of different primary color chips at different temperatures is different. Therefore, when the lamp bead includes multiple primary color chips, the preset function may include a preset function corresponding to each of the multiple primary color chips.

[0114] For example, taking the red primary color chip as an example, according to Figure 9 The temperature and brightness change curves of the red primary color chip shown in the figure can be used to obtain the brightness changes of the red primary color chip at different temperatures as shown in Table 1 below.

[0115] Table 1

[0116] Temperature (℃) -20 -10 0 10 20 30 40 50 60 70 brightness 128％ 121％ 115％ 110％ 104％ 97％ 92％ 85％ 78％ 73％

[0117] As can be seen from Table 1, the brightness of the red primary color chip changes by about 3% when the temperature changes by 5°C. By fitting the brightness of the red primary color chip at different temperatures, the preset function corresponding to the red primary color chip can be obtained.

[0118] The embodiment of the present application only uses Table 1 above as an example to exemplify the temperature and brightness of the red primary color chip, and Table 1 above does not limit the embodiment of the present application.

[0119] For example, after obtaining the temperature of the central area and the temperature of the edge area of ​​the display module model at -20℃, -10℃, 0℃, 10℃, 20℃, 30℃, 40℃, 50℃, 60℃, and 70℃, the brightness of the central area and the brightness of the edge area of ​​the display module model can be determined respectively by a preset function, and then the difference between the brightness of the edge area and the brightness of the central area can be determined to obtain the brightness difference shown in Table 2 below.

[0120] Table 2

[0121]

[0122] After the brightness differences between the multiple regions are determined, a coefficient set corresponding to the preset environmental state information may be determined according to the brightness differences between the multiple regions.

[0123] In some embodiments, the operation of the display screen control system determining the coefficient set corresponding to the preset environmental state information based on the brightness of each of the multiple areas may include: for any one of the multiple areas, determining the coefficient corresponding to each lamp bead model in the area based on the brightness difference between the area and the target area. The target area is the area with the lowest brightness among the multiple areas. Generally, the area with the lowest brightness is the area with the highest temperature among the multiple areas.

[0124] The coefficient set corresponding to the preset environmental state information includes coefficients corresponding to each lamp bead model in each of the multiple areas. That is, the coefficient set may include coefficients corresponding to each of the n lamp bead models in the display module model, also known as correction coefficients. These coefficients are used to control the brightness of the lamp beads in the display module.

[0125] The higher the brightness of the lamp beads in the display module, the faster the temperature of the lamp board rises. In this case, if the problem of uneven brightness in different areas is solved by increasing the brightness of the area with lower brightness among the multiple areas, the output power of the lamp beads in the area with lower brightness will be increased, which will further increase the temperature of the area and may cause the problem of uneven brightness in different areas of the display module to continue to occur. At the same time, too high an output power will also reduce the service life of the lamp beads. Therefore, in the embodiment of the present application, the problem of uneven brightness in different areas is solved by reducing the brightness of the area with higher brightness among the multiple areas. In this way, not only can the power consumption of the display module be reduced, but also the brightness consistency of different areas of the display module can be improved.

[0126] For example, for any one of the multiple areas, based on the brightness difference between the area and the target area, the operation of determining the coefficient corresponding to each lamp bead model in the area can be: dividing the brightness of the target area by the brightness of the area to obtain the coefficient corresponding to each lamp bead model in the area.

[0127] For example, Figure 10As shown in (a), in the absence of light, the display module model is subjected to a 1-hour thermal simulation, and the temperature of the central area is 55°C, the temperature of the near-edge area is 53°C, and the temperature of the edge area is 50°C. Determine the brightness corresponding to the temperature of the central area, the brightness corresponding to the temperature of the near-edge area, and the brightness corresponding to the temperature of the edge area respectively. Assume that the area with the lowest brightness is the central area, that is, the central area is the target area. Determine the ratio between the brightness of the central area and the brightness of the target area, and obtain the coefficient corresponding to all the lamp bead models in the central area is 1. Determine the ratio between the brightness of the near-edge area and the brightness of the target area, and obtain the coefficient corresponding to all the lamp bead models in the near-edge area is 98.8%. Determine the ratio between the brightness of the edge area and the brightness of the target area, and obtain the coefficient corresponding to all the lamp bead models in the edge area is 97.6%.

[0128] For example, Figure 10 As shown in (b), in the presence of light, the display module model is subjected to a 1-hour thermal simulation, and the temperature of the central area is 75°C, the temperature of the near-edge area is 65°C, and the temperature of the edge area is 60°C. Determine the brightness corresponding to the temperature of the central area, the brightness corresponding to the temperature of the near-edge area, and the brightness corresponding to the temperature of the edge area respectively. Assume that the area with the lowest brightness is the central area, that is, the central area is the target area. Determine the ratio between the brightness of the central area and the brightness of the target area, and obtain the coefficient corresponding to all the lamp bead models in the central area is 1. Determine the ratio between the brightness of the near-edge area and the brightness of the target area, and obtain the coefficient corresponding to all the lamp bead models in the near-edge area is 97%. Determine the ratio between the brightness of the edge area and the brightness of the target area, and obtain the coefficient corresponding to all the lamp bead models in the edge area is 94%.

[0129] Step C: the display screen control system generates a preset corresponding relationship according to the plurality of preset environmental state information and a coefficient set corresponding to each preset environmental information in the plurality of preset environmental state information.

[0130] For example, the display screen control system may associate each piece of preset environmental state information among the plurality of preset environmental state information with a coefficient set identifier of a corresponding coefficient set to obtain a preset corresponding relationship.

[0131] In some embodiments, after obtaining the coefficient set corresponding to each of the plurality of preset environmental state information, the display screen control system may store the coefficient set corresponding to each of the plurality of preset environmental state information in the second control module or the display module, obtaining a storage area identifier corresponding to each coefficient set as a coefficient set identifier. Each of the plurality of preset environmental state information is then associated with the coefficient set identifier of the corresponding coefficient set to obtain a preset correspondence, and the preset correspondence is sent to the first control module for storage.

[0132] In other embodiments, after obtaining the coefficient set corresponding to each preset environmental state information in the plurality of preset environmental state information, the display screen control system may generate a coefficient set identifier for each coefficient set. Each coefficient set is then associated with its coefficient set identifier to obtain a correspondence between the coefficient set and the coefficient set identifier, and this correspondence is stored in the second control module or the display module. Each preset environmental state information in the plurality of preset environmental state information is then associated with the coefficient set identifier of the corresponding coefficient set to obtain a preset correspondence, and this preset correspondence is sent to the first control module for storage.

[0133] In some embodiments, preset correspondences corresponding to different environmental states may be stored in the first control module. The first control module may selectively use different preset correspondences according to different environmental states.

[0134] For example, the correspondence between the light intensity information and the coefficient set identifier, as well as the correspondence between the time information and the coefficient set identifier, can be set in the first control module. When the display screen is running, if it is not currently in the time period from 19:00 to 8:00, the first control module can determine the coefficient set identifier to be applied based on the currently detected light intensity information through the correspondence between the light intensity information and the coefficient set identifier, and adjust the brightness of the lamp beads in the display screen accordingly. If it is currently in the time period from 19:00 to 8:00, the first control module can determine the coefficient set identifier to be applied based on the current time information through the correspondence between the time information and the coefficient set identifier, and adjust the brightness of the lamp beads in the display screen accordingly.

[0135] Figure 11 This is a flow chart of a display screen control method provided by an embodiment of the present application. Figure 11 , the method comprises the following steps:

[0136] Step 1101: The display screen control system periodically obtains the environmental status information of the display screen.

[0137] Optionally, step 1101 may be performed by the first control module.

[0138] The period for obtaining the environmental status information of the display screen can be preset.

[0139] By periodically acquiring the environmental status information of the display, changes in the environment in which the display is located can be promptly known. This helps to respond quickly to environmental changes and ensure the display stability of the display.

[0140] Step 1102: Each time the display screen control system obtains the environmental status information of the display screen, it determines the target coefficient set identifier from a preset correspondence relationship based on the environmental status information. The preset correspondence relationship is the correspondence between the environmental status information and the coefficient set identifier.

[0141] Optionally, step 1102 may be performed by the first control module.

[0142] The target coefficient set identifier is a coefficient set identifier corresponding to the environmental state information of the display screen.

[0143] The coefficient set identified by each coefficient set identifier in the preset correspondence includes n groups of coefficients. Each group of coefficients in the n groups of coefficients is used to control the brightness of n lamp beads in each display module in the display screen one by one. For example, when the lamp bead in the display module includes a primary color chip, each group of coefficients in the n groups of coefficients includes a coefficient for controlling the primary color chip; when the lamp bead in the display module includes multiple primary color chips, each group of coefficients in the n groups of coefficients includes multiple coefficients for controlling the multiple primary color chips one by one.

[0144] For example, when the environmental status information of the display screen includes light intensity information, the preset correspondence relationship may be the correspondence relationship between the light intensity information and the coefficient set identifier as shown in Table 3 below.

[0145] Table 3

[0146] Light intensity (lx, lux) Coefficient set identification 0-500 Coefficient set 1 500-2000 Coefficient set 2 2000-5000 Coefficient set 3 5000-10000 Coefficient set 4 10000-20000 Coefficient Set 5 Greater than 200,000 Coefficient Set 6

[0147] For another example, when the environmental status information of the display screen includes first temperature information, the preset corresponding relationship may be the corresponding relationship between the first temperature information and the coefficient set identifier as shown in Table 4 below.

[0148] Table 4

[0149] Temperature of the display screen's external environment (°C) Coefficient set identification Less than 20 Coefficient Set 7 20-25 Coefficient set 8 25-30 Coefficient Set 9 30-35 Coefficient set 10 35-40 Coefficient Set 11 More than 40 Coefficient set 12

[0150] For another example, when the environmental status information of the display screen includes time information, the preset corresponding relationship may be the corresponding relationship between the time information and the coefficient set identifier as shown in Table 5 below.

[0151] Table 5

[0152] time Coefficient set identification 0-9 o'clock Coefficient Set 13 10-11 o'clock Coefficient set 14 12-14 o'clock Coefficient Set 15 3-4 p.m. Coefficient set 16 5-6 p.m. Coefficient Set 17 7-11 p.m. Coefficient set 18

[0153] For another example, when the environmental status information of the display screen includes second temperature information, the preset corresponding relationship may be the corresponding relationship between the second temperature information and the coefficient set identifier as shown in Table 6 below.

[0154] Table 6

[0155] Temperature of the display screen's internal environment (°C) Coefficient set identification Less than 40 Coefficient set 10 40-50 Coefficient set 20 50-60 Coefficient Set 21 60-70 Coefficient set 22 70-80 Coefficient Set 23 Greater than 80 Coefficient set 24

[0156] The embodiments of the present application only illustrate the preset corresponding relationships using Tables 3 to 6 above as examples, and Tables 3 to 6 above do not limit the embodiments of the present application.

[0157] Step 1103: The display screen control system controls the brightness of n lamp beads in each display module in the display screen according to the n groups of coefficients in the target coefficient set identified by the target coefficient set identifier.

[0158] Because the preset correspondence includes coefficient set identifiers corresponding to different environmental state information, the corresponding coefficient set identifier can be accurately switched to ensure normal display of the display screen under different environmental states. Compared to the existing method of only setting fixed coefficients, the embodiment of the present application can adaptively adjust the coefficients to be applied according to the current environmental state, thereby ensuring that the display screen has a better display effect in different environmental states.

[0159] Optionally, the operation of step 1103 can be: the first control module sends a target coefficient set identifier to each of the m second control modules; for any one of the m second control modules, after receiving the target coefficient set identifier, the second control module obtains the target coefficient set according to the target coefficient set identifier, and controls the brightness of n lamp beads in each display module in a corresponding group of display modules according to the n groups of coefficients in the target coefficient set.

[0160] Because all display modules in the display screen are identical and in the same environment, the first control module, after determining the target coefficient set identifier, can send the target coefficient set identifier to each of the m second control modules, so that the m second control modules can adjust the corresponding m groups of display modules. This allows for more efficient control of the brightness of the lamp beads in all display modules in the display screen.

[0161] Optionally, the operation of the second control module obtaining the target coefficient set based on the target coefficient set identifier may include: the second control module obtaining the target coefficient set identified by the target coefficient set identifier from the second control module or the display module. For example, this operation may be performed by a first control unit in the second control module. The first control unit may obtain the target coefficient set identified by the target coefficient set identifier from a storage unit in the second control module or the display module.

[0162] Optionally, the operation of the second control module controlling the brightness of n lamp beads in each display module in a corresponding group of display modules based on the n sets of coefficients in the target coefficient set may be as follows: the second control module generates n sets of control signals corresponding to each display module in the corresponding group of display modules based on the target coefficient set, and outputs the n sets of control signals to each display module to control the brightness of the n lamp beads in each display module. For example, this operation may be performed by a second control unit in the second control module.

[0163] The control signal is a signal for controlling the brightness of the lamp beads. For example, the control signal can be a PWM signal.

[0164] For any display module, the n groups of coefficients in the target coefficient set correspond one-to-one to the n lamp beads in the display module. For any set of coefficients, one or more coefficients in the set correspond one-to-one to one or more primary color chips in a corresponding lamp bead.

[0165] For example, for any coefficient in any group of n groups of coefficients in the target coefficient set, the coefficient can be multiplied by the preset duty cycle related to the primary color chip corresponding to the coefficient to obtain the target duty cycle, and then a control signal with the target duty cycle is generated, which is used to control the brightness of the primary color chip.

[0166] The preset duty cycle can be pre-set. For example, the preset duty cycle can be set according to the screen brightness value of the display screen, and the screen brightness value can be a brightness value set by the system by default or a brightness value manually adjusted by the user.

[0167] In an embodiment of the present application, a display control system periodically acquires environmental status information for the display. Each time the environmental status information is acquired, a target coefficient set identifier is determined based on the environmental status information from a preset correspondence. The preset correspondence is a correspondence between environmental status information and coefficient set identifiers, with each coefficient set identified by the coefficient set identifier in the preset correspondence including n coefficient sets. The brightness of n lamp beads in each display module of the display is then controlled based on the n coefficient sets in the target coefficient set identified by the target coefficient set identifier. Because the preset correspondence includes coefficient set identifiers corresponding to different environmental conditions, the corresponding coefficient set identifier can be accurately switched to ensure normal display under different environmental conditions. This allows the coefficients to be adaptively adjusted based on the current environmental condition, ensuring that the display maintains high brightness consistency across different environmental conditions, thereby improving the display quality. Furthermore, because the environmental status information of the display is acquired periodically, the brightness of the display can be adjusted promptly in the event of changes in the environmental condition, thereby improving the display stability of the display.
