[0034] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0035] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0036] In addition, in order to better illustrate the present application, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0037] After the display screen leaves the factory, due to differences in process, the brightness and color of each lamp bead may be inconsistent, and display screen correction technology is needed to provide brightness and color correction for each lamp bead that makes up the display screen. Figure 1 A schematic diagram showing display correction technology is shown, such as Figure 1As shown, the display screen correction technology can be implemented using a high-resolution camera and a computer, and the computer is loaded with corresponding software and algorithms. The display screen correction process may include: (1) using a high-resolution camera to capture the display screen image; (2) obtaining the position and color of each lamp bead through a corresponding algorithm in the computer; (3) calculating the deviation between the color of each lamp bead and the target color; (4) performing coefficient compensation on each lamp bead to correct the deviation between the lamp bead color and the target color.

[0038] During the calibration process, obtaining the position of the lamp bead actually means obtaining the position of the lamp bead in the display driver chip, that is, obtaining the control address of the lamp bead. Figure 2 A schematic diagram showing the control address of the lamp bead, such as Figure 2 As shown, the control address of the lamp bead is indexed by the row address and the column address. For example, if you want to control the lamp bead in the R1 row and the C2 column to display white, then send a "white" control signal to the lamp bead with the control address (R1, C2), and the lamp bead at the corresponding position will display white.

[0039] Figure 3 Schematic diagram showing regularly arranged lamp beads and irregularly arranged lamp beads, such as Figure 3 As shown in (a), if the lamp beads are arranged in a regular rectangular shape, that is, the lamp beads are aligned in rows and columns, the row and column of each lamp bead can be determined by analyzing the arrangement of the lamp bead images in the display screen image, thereby determining the control address of each lamp bead; however, Figure 3 As shown in (b), if the lamp beads are not arranged in a regular rectangular shape, it is difficult to determine the control address of the lamp beads using the above method.

[0040] In view of this, the present application proposes a lamp bead position encoding method and a lamp bead position decoding method. According to the lamp bead position encoding method of the present application, the lamp bead serial number (corresponding to the control address of the lamp bead) can be conveniently encoded to obtain the lamp bead position code, and the lamp bead position code can be conveniently and accurately transmitted; according to the lamp bead position decoding method of the present application, for lamp beads arranged in any arrangement on the display screen, the lamp bead serial number can be quickly and accurately obtained, and then the lamp bead control address can be quickly and accurately obtained.

[0041] Figure 4 A flow chart of a lamp bead position coding method according to an embodiment of the present application is shown, wherein the lamp bead is located in a display screen (the lamp bead can be located in the same display screen or in a display screen composed of multiple display screens), and the method can be implemented by a display driver chip connected to the display screen, such as Figure 4 As shown, the method may include:

[0042] S401. Determine the lamp bead serial number of each lamp bead in the display screen; wherein different lamp beads have different lamp bead serial numbers, and the lamp bead serial number is an integer greater than or equal to 0.

[0043] Exemplarily, a lamp bead serial number may be assigned to each lamp bead in the display screen in a manner of increasing by 1 starting from 0. If the total number of lamp beads in the display screen is N, the largest lamp bead serial number is N-1.

[0044] For example, when the lamp beads in the display screen are arranged regularly, the lamp bead serial number can be assigned to each lamp bead in the order of rows or columns. For example, the lamp beads in the display screen are arranged in H rows and W columns, and the lamp bead serial number S of the lamp bead in the i-th row and j-th column is (i,j) It can be (i-1)*W+(j-1).

[0045] For example, when the lamp beads in the display screen are arranged irregularly, a lamp bead serial number can be randomly assigned to each lamp bead.

[0046] It should be noted that the present application does not limit the implementation method of determining the lamp bead serial number of each lamp bead in the display screen, as long as each lamp bead has a unique corresponding lamp bead serial number.

[0047] In a possible implementation, the method may further include: determining the correspondence between the lamp bead serial number of each lamp bead and the preset control address of each lamp bead; the control address is used to control the working state of the lamp bead, for example, the color, brightness, luminous time, etc. of the lamp bead can be controlled.

[0048] Exemplarily, when determining the lamp bead serial number of each lamp bead, the correspondence between the lamp bead serial number of each lamp bead and its preset control address can be determined at the same time, and the correspondence between the lamp bead serial number of each lamp bead and its control address can be recorded. For example, the lamp bead serial number of the lamp bead with a control address of (1,1) is 7, and the correspondence between the control address (1,1) and the lamp bead serial number 7 can be recorded in the display driver chip.

[0049] Exemplarily, the display screen may be any one of a light emitting diode display screen, a micro light emitting diode display screen, a mini light emitting diode display screen, a quantum dot light emitting diode display screen, and an organic light emitting diode display screen, and the lamp beads may be LED lamp beads.

[0050] S402, encode the lamp bead serial number of each lamp bead in d-base, and use the d-base code corresponding to the lamp bead serial number of each lamp bead as the position code of each lamp bead; wherein the code lengths of the position codes of each lamp bead are the same; d is a positive integer; d≥2.

[0051] For example, the d in the d-ary encoding and the encoding length L of the position encoding of each lamp bead satisfy: d L >Smax ; Among them, S max Indicates the largest lamp bead number among the lamp bead numbers of all lamp beads; L is a positive integer.

[0052] As an example, the code length L may be the code length corresponding to the d-binary code of the maximum lamp bead number. For example, the maximum lamp bead number is 10, d=2, and the binary code of 10 is 0101, then the code length L may be 4.

[0053] S403, setting the flashing mode of each lamp bead according to the position code of each lamp bead; wherein different lamp beads have different flashing modes.

[0054] In a possible implementation, setting the flashing mode of each lamp bead according to the position code of each lamp bead may include:

[0055] (1) Determine d brightness levels.

[0056] (2) According to the k-th bit code in the position code of each lamp bead, determine the brightness level corresponding to the k-th flash of each lamp bead from the d brightness levels; wherein the number of flashes of each lamp bead is L times; 1≤k≤L.

[0057] In another possible implementation, setting the flashing mode of each lamp bead according to the position code of each lamp bead may include:

[0058] (1) Determine d colors.

[0059] (2) According to the k-th bit code in the position code of each lamp bead, determine the color corresponding to the k-th flash of each lamp bead from the d colors; wherein the number of flashes of each lamp bead is L times; 1≤k≤L.

[0060] In one embodiment, it is assumed that there are 5 lamp beads in the display screen, and the lamp bead serial numbers are 0, 1, 2, 3, and 4. If d=2, the lamp bead serial numbers of the 5 lamp beads are binary coded respectively, and the coding length can be 3. The 3-bit binary code corresponding to the lamp bead serial number of each lamp bead is the position code of each lamp bead. The corresponding relationship between the lamp bead serial number and the position code of each lamp bead is shown in Table 1.

[0061] Table 1

[0062] Lamp bead serial number Lamp bead position coding 0 000 1 100 2 010 3 110 4 001

[0063] The flashing mode of each lamp bead can be set according to the position code of each lamp bead. Since the code length is 3, the number of flashes of each lamp bead can be 3 times.

[0064] As an example, two brightness levels can be determined, namely bright and dark, and if the code is 0, it corresponds to dark, and if the code is 1, it corresponds to bright, then the brightness level corresponding to the kth flash of each lamp bead can be determined according to the kth bit code in the position code of each lamp bead. For example, for the lamp bead with the serial number 3, the first bit code in its position code is 1, then the lamp bead can be set to brighten when it flashes for the first time; if the second bit code in its position code is 1, then the lamp bead can be set to brighten when it flashes for the second time; if the third bit code in its position code is 0, then the lamp bead can be set to not brighten when it flashes for the third time.

[0065] As another example, two colors can be determined, red and green, and the code 0 corresponds to red and the code 1 corresponds to green. Then, the color corresponding to the kth flash of each lamp bead can be determined according to the kth bit code in the position code of each lamp bead. For example, for the lamp bead with the serial number 3, the color of the lamp bead can be set to green when it flashes for the first time, green when it flashes for the second time, and red when it flashes for the third time.

[0066] In another embodiment, if d=3, the lamp bead serial number of each lamp bead in the display screen is ternary-encoded, and assuming that the maximum lamp bead serial number is 8, the encoding length can be 3. As an example, three brightness levels can be determined, namely, off, brightness 1, and brightness 2, and the code 0 corresponds to off, the code 1 corresponds to brightness 1, and the code 2 corresponds to brightness 2. Then, according to the k-th bit code in the position code of each lamp bead, the brightness level corresponding to the k-th flash of each lamp bead can be determined; for example, for the lamp bead with a serial number of 7, its position code is 120, then the brightness of the lamp bead can be set to brightness 1 when it flashes for the first time, the brightness of the second flash is set to brightness 2, and it can be set to off when it flashes for the third time. As another example, three colors can be determined, namely red, green and blue. Let the code 0 correspond to red, the code 1 correspond to green, and the code 2 correspond to blue. Then, according to the k-th bit code in the position code of each lamp bead, the color corresponding to the k-th flash of each lamp bead can be determined; for example, for the lamp bead number 7, its position code is 120, then the color of the lamp bead can be set to green when it flashes for the first time, blue when it flashes for the second time, and red when it flashes for the third time.

[0067] In a possible implementation, the method may further include: based on the control address of each lamp bead, controlling each lamp bead to flash according to its corresponding flashing mode; wherein the flashing frequencies of each lamp bead are the same.

[0068] The lamp bead position coding method of the embodiment of the present application assigns a lamp bead serial number to each lamp bead in the display screen, uses the d-binary code corresponding to the lamp bead serial number of each lamp bead as the position code of each lamp bead, sets the flashing mode of each lamp bead according to the position code, controls each lamp bead to flash according to its corresponding position code to transmit the position code of each lamp bead, and can conveniently code the position of each lamp bead and conveniently and accurately transmit the position code of each lamp bead. The lamp bead serial number of the lamp bead corresponds to its control address, so the position code of the lamp bead also corresponds to the control address of the lamp bead, that is, the control address of each lamp bead can be conveniently and accurately transmitted through the lamp bead position coding method of the embodiment of the present application.

[0069] After executing the lamp bead position encoding method of the embodiment of the present application, the value of d, the coding length L, d brightness levels (or d colors), and the coding corresponding to each brightness level (or each color) can be recorded in the display driver chip. Before executing the lamp bead position decoding method of the embodiment of the present application, the above information can be obtained from the display driver chip.

[0070] Figure 5 A flowchart of a lamp bead position decoding method according to an embodiment of the present application is shown. The method is used to decode the position of a lamp bead according to Figure 4 The lamp bead position coding method shown in the figure decodes the position of the lamp bead after position coding. The method can be executed by a device with processing capability such as a processor or a server. The method may include:

[0071] S501. Obtain L first images obtained by photographing the display screen; wherein L represents the coding length of the position coding of each lamp bead in the display screen; the mth first image among the L first images is an image captured when each lamp bead flashes for the mth time according to its corresponding flashing mode; 1≤m≤L; the position coding of each lamp bead is obtained by the above-mentioned lamp bead position coding method.

[0072] Exemplarily, the display screen may be photographed by a camera to obtain L first images, and the camera may be a high-resolution camera.

[0073] Exemplarily, the frequency of the camera taking images can be the same as the flashing frequency of the lamp beads. The display driver chip can control the lamp beads in the display screen to flash according to their corresponding flashing modes. When the lamp beads flash for the mth time, the camera can capture the mth first image.

[0074] In a possible implementation, before acquiring L first images obtained by photographing the display screen, the method may further include:

[0075] (1) Acquire a second image of the display screen by photographing the display screen when all the lamp beads in the display screen are lit.

[0076] Exemplarily, the display driver chip can control all lamp beads in the display screen to light up, and at this time, a camera can be used to shoot the display screen to obtain a second image.

[0077] (2) Determine the camera coordinates of each lamp bead according to the second image; the camera coordinates of each lamp bead are used to describe the position of each lamp bead in the second image.

[0078] Exemplarily, a rectangular coordinate system can be established based on the second image. For example, a rectangular coordinate system can be established with the long side of the second image as the x-axis and the wide side as the y-axis. The lamp bead image corresponding to each lamp bead can be identified based on the second image. The coordinates of the center point of each lamp bead image in the rectangular coordinate system can be used as the camera coordinates of each lamp bead. The camera coordinates can describe the position of each lamp bead in the second image. The process of identifying the lamp bead image corresponding to each lamp bead and determining the coordinates of the center point of each lamp bead image can refer to the relevant technology.

[0079] Exemplarily, the relative position relationship between the camera and the display screen when shooting the second image is consistent with the relative position relationship between the camera and the display screen when shooting the L first images.

[0080] S502: Determine the position code of each lamp bead according to the L first images.

[0081] In a possible implementation, when each lamp bead flashes at d brightness levels, determining the position code of each lamp bead according to the L first images may include:

[0082] (1) Determine the brightness level of each lamp bead in the L first images.

[0083] Exemplarily, determining the brightness level of each lamp bead in the L first images may include:

[0084] Determine the position of each lamp bead in the L first images according to the camera coordinates of each lamp bead;

[0085] According to the position of each lamp bead in the L first images, the brightness level of each lamp bead in the L first images is determined.

[0086] For the L first images, a rectangular coordinate system can be established in the same way as for the second image. Since the positional relationship between the camera and the display screen does not change when taking the second image and the L first images, the position of each lamp bead in the second image and the L first images will not change. For any lamp bead in the display screen, the camera coordinates of the lamp bead in the second image are the camera coordinates of the lamp bead in the L first images, so that the position of each lamp bead in the L first images can be determined, thereby determining the brightness of each lamp bead in each first image. The method for determining the brightness of the lamp bead in each first image can refer to the relevant technology. After determining the brightness of each lamp bead in each first image, the brightness level of the lamp bead in each first image can be determined from d brightness levels.

[0087] (2) Determine the m-th bit code in the position code of each lamp bead according to the brightness level of each lamp bead in the m-th first image.

[0088] The code corresponding to the brightness level of the lamp bead in the mth first image is the mth bit code in the lamp bead position code. According to the brightness level of the lamp bead in each first image, the L-bit position code of the lamp bead can be determined.

[0089] Exemplarily, the signal-to-noise ratio of the L first images satisfies: log d SNR>d; where SNR represents the signal-to-noise ratio of L first images. The higher the signal-to-noise ratio of the first image, the more brightness levels the first image can distinguish. For a lamp bead that uses d-ary encoding for position encoding, when it flashes in a corresponding flashing mode, the brightness change can include at most d brightness levels. When the signal-to-noise ratio of the first image satisfies log d Only when SNR>d can d brightness levels be distinguished according to the first image, thereby determining the position code of each bit of the lamp bead.

[0090] In another possible implementation, when each lamp bead flashes in d colors, determining the position code of each lamp bead according to the L first images may include:

[0091] (1) Determine the color of each lamp bead in the L first images.

[0092] (2) Determine the m-th bit code in the position code of each lamp bead according to the color of each lamp bead in the m-th first image.

[0093] The steps of determining the position code of each lamp bead when each lamp bead flashes according to d colors can refer to the above steps of determining the position code of each lamp bead when each lamp bead flashes according to d brightness levels, which will not be repeated here.

[0094] S503, performing d-base decoding on the position code of each lamp bead to determine the lamp bead serial number of each lamp bead.

[0095] In a possible implementation, the method may further include: determining the control address of each lamp bead according to a correspondence between a lamp bead serial number of each lamp bead and a preset control address of each lamp bead.

[0096] Exemplarily, the correspondence between the lamp bead serial number and the control address can be obtained from the display driver chip, and the control address of each lamp bead in the display screen can be determined according to the correspondence.

[0097] The lamp bead position decoding method of the embodiment of the present application takes L display screen images when the lamp beads flash according to their corresponding position codes, determines the position code of each lamp bead according to the brightness of each lamp bead in the L display screen images, and obtains the lamp bead serial number of each lamp bead by decoding the position code. For lamp beads arranged in any arrangement in the display screen, the lamp bead serial number of each lamp bead in the display screen can be quickly and accurately determined, and then the control address of each lamp bead can be quickly and accurately determined according to the correspondence between the lamp bead serial number and the control address.

[0098] In one embodiment, assuming that the display screen contains 7 lamp beads, the control addresses are recorded as (R0, C0), (R1, C1), (R2, C2), (R3, C3), (R4, C4), (R5, C5), (R6, C6). The lamp bead positions can be encoded by a display driver chip connected to the display screen. First, assign a lamp bead serial number to each lamp bead. The lamp bead serial numbers corresponding to the lamp bead with control addresses (R0, C0), (R1, C1), (R2, C2), (R3, C3), (R4, C4), (R5, C5), (R6, C6) are 0, 1, 2, 3, 4, 5, and 6, respectively. Then, the lamp bead serial number can be binary-coded (i.e., d=2), and the coding length is 3 (i.e., L=3). The lamp bead flashing mode can be set according to the lamp bead position coding and the lamp bead can be controlled to flash according to the position coding. The number of flashes is 3 times. The brightness level at the i-th flashing is determined according to the i-th bit coding in the lamp bead position coding. The coding of 0 corresponds to off light, and the coding of 1 corresponds to light. After the lamp bead position coding is performed, the correspondence between the lamp bead serial number and the control address, d=2, L=3, 2 brightness levels (on and off light), and the coding corresponding to each brightness level (on light corresponds to coding 1, off light corresponds to coding 0) can be recorded in the display driver chip.

[0099] The position of the lamp beads can be decoded by using a camera and a computer. Before decoding the position of the lamp beads, the computer can obtain the above-mentioned recorded information from the display driver chip. Figure 6A schematic diagram showing a method for decoding the position of a lamp bead according to an embodiment of the present application is shown as follows: Figure 6 As shown, the camera can capture a display screen image when the display driver chip controls the lamp beads in the display screen to be fully lit (i.e. Figure 6 The computer can obtain image 6-1 and determine the camera coordinates of each lamp bead based on image 6-1. A rectangular coordinate system can be established with the long side of image 6-1 as the x-axis, the wide side as the y-axis, and the vertex in the upper left corner as the origin, and the lamp bead image corresponding to each lamp bead in image 6-1 can be identified. The coordinates of the center point of each lamp bead image in the rectangular coordinate system are used as the camera coordinates of each lamp bead. Then, the camera can continuously take three display screen images (i.e., when the display driver chip controls each lamp bead to flash according to the position code) Figure 6 The shooting frequency is the same as the flashing frequency of the lamp beads, that is, image 6-2a is the display screen image taken when the lamp beads flash for the first time, image 6-2b is the display screen image taken when the lamp beads flash for the second time, and image 6-2c is the display screen image taken when the lamp beads flash for the third time. The relative position relationship between the camera and the display screen remains unchanged when shooting images 6-1, 6-2a, 6-2b, and 6-2c. The computer can obtain images 6-2a, 6-2b, and 6-2c, and determine the position of each lamp bead in images 6-2a, 6-2b, and 6-2c according to the camera coordinates of each lamp bead, thereby determining the brightness of each lamp bead in images 6-2a, 6-2b, and 6-2c. If the lamp bead is not lit in the i-th image in images 6-2a, 6-2b, and 6-2c, the i-th bit in the position code of the lamp bead is 0; if the lamp bead is lit in the i-th image in images 6-2a, 6-2b, and 6-2c, the i-th bit in the position code of the lamp bead is 1; based on this, the position code of each lamp bead can be determined. The position code of each lamp bead is binary decoded to determine the lamp bead serial number of each lamp bead. According to the corresponding relationship between the lamp bead serial number and the control address, the control address of each lamp bead can be obtained.

[0100] For example, for the lamp bead located in the upper left corner of the display screen image, it is lit in image 6-2a, and the first bit of the position code of the lamp bead is 1; it is not lit in image 6-2b, and the second bit of the position code of the lamp bead is 0; it is not lit in image 6-2c, and the third bit of the position code of the lamp bead is 0; in this way, it can be determined that the position code of the lamp bead is 100, and binary decoding of the position code shows that the lamp bead serial number of the lamp bead is 1. According to the corresponding relationship between the lamp bead serial number and the control address, it can be known that the control address of the lamp bead is (R1, C1). According to the above process, the lamp bead serial number of each lamp bead in the display screen can be decoded, so that the control address of each lamp bead can be determined. Table 2 shows the relationship between the lamp bead serial number, the control address, the position code of the lamp bead, the camera coordinates of the lamp bead, the brightness of the lamp bead and the corresponding code in image 6-2a, the brightness of the lamp bead and the corresponding code in image 6-2b, the brightness of the lamp bead and the corresponding code in image 6-2c, and the decoded lamp bead serial number.
