Description

Technical Field

[0001] The present invention relates to the field of display control, and particularly to a design method for a segment code screen, a control method for a segment code screen, a device and a device. Background Art

[0002] An electronic paper screen is a display screen made using electrophoretic display technology. By applying a voltage to each driving electrode through a control circuit on a driving substrate, colored electrophoretic particles in an electronic paper film are driven to move to achieve image display. As a reflective display screen, the electronic paper screen can maintain the image for a long time without continuous refreshing after the image is updated, so the power consumption is very low. Due to its many characteristics such as low power consumption, wide viewing angle, high contrast, and eye protection, the electronic paper screen is increasingly widely used in many fields such as electronic price tags, e-books, and billboards.

[0003] In the application of electronic price tags, in order to supplement the display of product information, such as promotion, green product, new product, out of stock, low price, etc., as Figure 1 shown, an additional accessory for supplementary display is usually added to the electronic price tag.

At the same time, one type of accessory can only display one type of product information or status. Corresponding to different information or statuses, as Figure 2 shown, different types of accessories need to be replaced, resulting in a wide variety and large quantity of accessories. In addition, when the product information or status changes, manual replacement of the accessory is required in a timely manner, resulting in low display efficiency and high labor costs.

[0049] To enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0050] It should be noted that the terms "first", "second", etc. in the present invention are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0051] Figure 3A The flowchart of a design method for a segment code screen provided by an embodiment of the present invention. This embodiment is applicable to the situation where, before using the segment code screen to supplement and display the information pattern of the commodity, the hardware of the segment code screen is specifically designed based on the specific content of the information pattern. This method can be executed by a design device of the segment code screen. The device can be implemented in the form of hardware and / or software, and the device can be configured in an electronic device with corresponding data processing capabilities, such as a design system of the segment code screen. As Figure 3A shown, the method includes:

[0052] S310. Generate a coding data matrix according to the pattern matrix of at least two patterns in the pattern area of the segment code screen.

[0053] S320. Determine the valid segment code sequence in the segment code sequence according to the coding data matrix.

[0054] S330. Determine the design scheme of the segment code IC and the segment code electrodes of the segment code screen according to the valid segment code sequence.

[0055] Among them, the segment code screen is an information supplement screen for the electronic price tag, and the pattern is the information pattern of the commodity corresponding to the electronic price tag, including two forms: text and graphics. Examples of text include "Everyday Low Price", "LowerPrice", "Member Price", "Special", "New"; examples of graphics include a star (general recommendation), two stars (highly recommended), and three stars (strongly recommended). As Figure 3B shown, different from the prior art, in the present invention, the accessory for supplementary display that is matched with the electronic price tag is an active accessory, and the active accessory also includes two parts: a hollowed-out area and a display area. The hollowed-out area is used to match the pattern area of the electronic price tag, and the display area is used to display the information pattern of the commodity corresponding to the electronic price tag that needs to be supplemented and displayed.

[0056] To make the pattern most prominent, the pattern is usually set at the center of the area with the largest display area of the active accessory. As Figure 3C shown, the pattern can be set to be displayed in the middle area on the lower side of the active accessory. According to the pattern areas occupied by the patterns in different images, a minimized common pattern area is determined. This minimized common pattern area is a rectangular area and can exactly cover the pattern data in all images. Therefore, the display area is further divided into two parts: 1. The minimized common pattern area determined in the above manner; 2. Other areas outside the pattern area. Similar to the passive accessory, the background area of the active accessory in the present invention is a solid color or a simple graphic, and the existing conventional segment code electrode design scheme can be adopted. Therefore, in the present invention, the background area is not described in detail, and only the design scheme of the segment code electrode in the pattern area is described. As Figure 3D shown, it shows a schematic structural diagram of the segment code screen used as an active accessory. Here, the electronic paper segment code screen is taken as an example for illustration. From Figure 3D it can be seen that the electronic paper segment code screen mainly includes the following parts:

[0057] 1. Driving substrate: It includes two parts: a substrate and segment code electrodes. Through processes such as coating, exposure, development, and etching, a driving circuit is formed on the substrate, and at the same time, it is used to connect to the external circuit PCB to realize the driving and control of the segment code screen by the external circuit PCB.

[0058] 2. Ag glue dots: They are arranged between the driving substrate and the FPL. At the same time, Ag glue dot electrodes are arranged on the driving substrate at the corresponding positions of the Ag glue dots. The Ag glue dots are used to connect the Ag glue dot electrodes on the driving substrate and the ITO electrodes on the FPL, and the main component is conductive silver glue.

[0059] 3. FPL: Front Plane Laminate, the front plane laminate, which is the electronic paper film used to display the image actually seen by the human eye. The FPL is attached to the driving substrate. An electric field is formed between the driving electrodes on the driving substrate and the ITO electrodes on the FPL to drive the electronic ink in the FPL to display the image.

[0060] 4. PS: Attached to the top of the FPL, with a larger size than the FPL and wrapping the FPL at the edges, used to protect the FPL and isolate moisture.

[0061] 5. Edge sealing glue: Coated on the four peripheral edges of the PS, used to fill the gap between the PS and the driving substrate to further isolate moisture.

[0062] 6. PCB: Printed Circuit Board, the printed circuit board, as an external control circuit, provides power supply, control timing, data signals, etc. for the screen.

[0063] 7. Segment code IC: Receives the control signals and data signals transmitted by the MCU and converts the signals into the voltage and timing for refreshing the driving electronic paper segment code screen.

[0064] 8. MCU: Micro Controller Unit, the microcontroller, the main control unit of the external circuit of the electronic paper segment code screen.

[0065] Specifically, by performing dot matrix processing on the pattern area at a certain resolution, a dot matrix matrix can be obtained. For each pattern to be displayed, specific grid points in the dot matrix matrix are assigned values to obtain the pattern matrix of the pattern in the pattern area, realizing the matrixization and digitization of the pattern image. Taking a dot matrix matrix of 35 columns and 16 rows (i.e., the resolution A*B of the pattern area is 35H*16V, where A corresponds to the number of columns and B corresponds to the number of rows) as an example, the pattern matrices of different patterns are respectively as Figure 3E 、 3F 、3G, 3H, 3I are respectively shown. The grid points corresponding to the pattern are identified by the number 1 and gray filling, and the grid points outside the pattern are identified by the number 0 and white filling.

[0066] After obtaining the pattern matrices of each pattern, based on a specific coding function, the pattern matrices of each pattern are uniformly coded to obtain a coded data matrix. Taking the Figure 3E - 3I shown pattern matrix as an example, the Figure 3JThe encoded data matrix shown. The encoding results of each lattice point in the encoded data matrix represent the segment code sequence corresponding to that lattice point. Lattice points with the same value in the encoded data matrix correspond to the same segment code sequence, and lattice points with different values in the encoded data matrix correspond to different segment code sequences. The lattice points corresponding to the same segment code sequence always maintain the same state, so that subsequently, the state of all lattice points corresponding to a segment code sequence can be changed as a whole by controlling the state of the segment code sequence. As Figure 3K shown, when using the segment code screen subsequently, the state of all lattice points with an encoding result of 0 in the pattern area can be changed by controlling the state of segment code sequence 0, so that they are uniformly displayed or not displayed.

[0067] For N (N is the number of patterns) dot-matrix pattern matrices, each pattern matrix only includes two states: a solid-color pattern and a solid-color background (i.e., pattern lattice points and non-pattern lattice points). Assuming that theoretically M1 segment code sequences are required to encode the pattern matrix, then M1 = 2^N (i.e., M1 is equal to 2 to the power of N). By statistically summarizing the segment code sequences that appear in the encoded data matrix, the invalid segment code sequences and valid segment code sequences in the segment code sequences can be obtained.

[0068] According to the corresponding rules between the encoded data matrix, the valid segment code sequences, and the output pins of the segment code IC, the segmentation and combination of the segment code electrodes on the segment code screen driving substrate are completed, and the segmented and combined segment code electrodes are connected to the corresponding output pins of the segment code IC to complete the design of the driving substrate.

[0069] In the embodiment of the present invention, the passive accessories of the electronic price tag are upgraded to active accessories, eliminating the need for employees to manually replace the accessories, improving the display efficiency of the information pattern; at the same time, according to the pattern to be displayed, the hardware circuit of the active accessory is simplified specifically, improving the battery life of the active accessory and eliminating the need for frequent battery replacement or charging, further improving the display efficiency of the information pattern.

[0070] Figure 4A The flowchart of a design method for a segment code screen provided by another embodiment of the present invention. This embodiment is optimized and improved on the basis of the above embodiment. As Figure 4A shown, the method includes:

[0071] S410. Perform dot-matrix processing on the pattern area of the segment code screen to obtain a dot-matrix matrix; for each pattern, assign values to the lattice points in the dot-matrix matrix according to the display content of the pattern to obtain the pattern matrix of the pattern in the pattern area.

[0072] S420. Generate an encoded data matrix according to a preset encoding function and the pattern matrices of each pattern in the pattern area.

[0073] Specifically, according to the display resolution of the pattern area, the pattern area is discretely divided according to the coordinate system of rows (Row) and columns (Column), forming a matrix structure composed of multiple lattice points. The position of each lattice point is uniquely identified by its coordinates (i, j), where i represents the row number and j represents the column number. For each pattern, according to the display content of the pattern, determine the lattice points that need to be lit and the lattice points that do not need to be lit in the dot matrix when displaying the pattern. Assign the value of 1 to the lattice points that need to be lit and the value of 0 to the lattice points that do not need to be lit, obtaining the pattern matrix of the pattern in the pattern area. Through this assignment method, the pattern matrices of each pattern in the pattern area are obtained respectively. Preset an encoding function, and encode the pattern matrices of each pattern in the pattern area according to this encoding function to obtain an encoded data matrix.

[0074] Based on the above embodiments, optionally, the generating the encoded data matrix according to the preset encoding function and the pattern matrices of each pattern in the pattern area includes:

[0075] For each lattice point, determine the values of the lattice point in different pattern matrices;

[0076] Substitute the values of the lattice point in different pattern matrices into the encoding function to obtain the encoding result of the lattice point;

[0077] Generate an encoded data matrix according to the encoding results of each lattice point.

[0078] Specifically, for each lattice point, according to the multiple pattern matrices generated previously, determine its values in different pattern matrices. For example, in pattern matrix 1, its value is 1; in pattern matrix 2, its value is 0. The independent variable of the encoding function is the values of the lattice point in different pattern matrices, and the dependent variable is the encoding result of the lattice point. Substitute the values of the lattice point in different pattern matrices into the encoding function to obtain the encoding result of the lattice point. Repeat multiple times to obtain the encoding results of each lattice point. Generate an encoded data matrix according to the positions and encoding results of each lattice point.

[0079] Exemplarily, let X1(i, j), X2(i, j), X3(i, j), X4(i, j), X5(i, j) represent the values of the lattice point in the i-th row and j-th column of pattern matrices 1 - 5 respectively (where i and j are positive numbers, and 1 ≤ i ≤ 16, 1 ≤ j ≤ 35). Let Y(i, j) represent the encoding result of the lattice point in the i-th row and j-th column of the encoded data matrix. Set the encoding function as: Y(i, j) = X5(i, j) * 16 + X4(i, j) * 8 + X3(i, j) * 4 + X2(i, j) * 2 + X1(i, j) * 1.

[0080] For the lattice point at the 7th row (i = 7) and the 8th column (j = 8), the values X1(7,8), X2(7,8), X3(7,8), X4(7,8), X5(7,8) in the pattern matrices 1 - 5 are 1, 1, 0, 0, 0 respectively. Then its encoding result is Y(7,8) = 0*16 + 0*8 + 0*4 + 1*2 + 1*1 = 3.

[0081] S430. Determine the number of lattice points corresponding to each segment code sequence according to the encoded data matrix; determine the segment code sequences with non - zero numbers of corresponding lattice points as valid segment code sequences.

[0082] Specifically, there are significant differences in the distributions of different segment code sequences and the corresponding numbers of lattice points. Count the number of lattice points corresponding to each segment code sequence according to the encoded data matrix. Determine the segment code sequences with non - zero numbers of corresponding lattice points as valid segment code sequences in the segment code sequences, and determine the segment code sequences with zero numbers of corresponding lattice points as invalid segment code sequences in the segment code sequences.

[0083] Exemplarily, according to Figure 3J the encoded data matrix shown, the statistical result as shown in Figure 4B can be obtained. The numbers of lattice points corresponding to the segment code sequences 0 - 31 are: 231, 86, 24, 4, 14, 41, 28, 33, 42, 4, 2, 1, 0, 2, 3, 3, 12, 1, 3, 1, 0, 2, 2, 1, 15, 1, 1, 0, 0, 1, 2, 0. From the above data, it can be seen that: 1. The distributions of the numbers of lattice points corresponding to the segment code sequences are very uneven. Approximately one - third of the segment code sequences have more than 10 lattice points, and approximately two - thirds of the segment code sequences have less than 10 lattice points; 2. The numbers of lattice points corresponding to the segment code sequences 12, 20, 27, 28, 31 are 0. Define the segment code sequences with 0 lattice points as invalid segment code series, and define the segment code sequences with non - zero lattice points as valid segment code series. Assume the number of invalid segment code sequences in the segment code sequences is M2, then M2 = 5. Subtract the number of invalid encodings M2 from the number of segment code sequences M1 to obtain the number of valid encoding sequences M, that is, M = M1 - M2. In this example, M = M1 - M2 = 2^5 - 5 = 32 - 5 = 27, that is, the number of valid segment code sequences is 27.

[0084] S440. For each valid segment code sequence, design a corresponding segment code IC output pin for the valid segment code sequence, and divide and combine the electrodes of the lattice points corresponding to the valid segment code sequence into the segment code electrodes of the valid segment code sequence.

[0085] S450. Connect the segment code IC output pins and the segment code electrodes of the valid segment code sequence.

[0086] Specifically, for the invalid segment code electrodes with a corresponding lattice point count of 0, no segment code IC is required for driving. Therefore, only the part of the valid segment code sequence needs to be considered in the correspondence rule between the segment code sequence and the output pins of the segment code IC. For each valid segment code sequence, design the corresponding output pins of the segment code IC, and combine and cut the electrodes of all lattice points corresponding to the valid segment code sequence to make it an integrated entity as the segment code electrode corresponding to the valid segment code sequence. Connect the segment code electrode corresponding to the valid segment code sequence with the output pins of the segment code IC to complete the design of the relevant hardware for the segment code sequence.

[0087] Exemplarily, according to Figure 4B the statistical results shown, Figure 4C the design scheme shown can be obtained. For the invalid segment code sequences 12, 20, 27, 28, 31, since the corresponding lattice point count is 0, no corresponding output pins of the segment code IC are designed for them. The remaining 27 valid segment code sequences respectively correspond to 27 output pins of the segment code IC from S1 to S27.

[0088] In the embodiment of the present invention, by screening the segment code sequences and only designing the corresponding output pins of the segment code IC and segment code electrodes for the valid segment code sequences, the accurate simplification of the hardware circuit of the segment code screen is realized.

[0089] Figure 5A The figure is a flowchart of a control method for a segment code screen provided by an embodiment of the present invention. This embodiment is applicable to the situation of displaying the information pattern of a commodity on a segment code screen that has been designed and manufactured. This method can be executed by the control device of the segment code screen. The device can be implemented in the form of hardware and / or software, and can be configured in an electronic device with corresponding data processing capabilities, such as the main controller of the segment code screen. As Figure 5A shown, the method includes:

[0090] S510. Determine the target segment code sequence that matches the target pattern.

[0091] S520. Supply power to the target segment code electrode of the segment code screen according to the target segment code sequence, so that the segment code screen displays the target pattern.

[0092] Wherein, the segment code screen is designed by the segment code screen design method described in any embodiment of the present invention.

[0093] Specifically, the segment code sequences matched by different patterns are different from each other. The segment code sequences matched by each pattern have been determined during the segment code screen design stage. After the design is completed, the segment code sequences matched by each pattern are recorded. When using the segment code screen, determine the target segment code sequence that matches it and is pre-recorded according to the target pattern to be displayed. Power the target segment code electrodes of the segment code screen according to the target segment code sequence, so that the grid points corresponding to the target segment code electrodes are lit, and the target pattern is displayed on the segment code screen.

[0094] The determination logic of the segment code sequences matched by each pattern is as follows:

[0095] For each pattern, the segment code sequence corresponding to the grid points with a value of 1 in the pattern matrix of the pattern in the coding data matrix is determined as the segment code sequence matched by the pattern.

[0096] Exemplarily, as Figure 5B shown, for Figure 3G Pattern 3 shown, the segment code sequences corresponding to the grid points with a value of 1 in its pattern matrix in the coding data matrix are only 4, 5, 6, 7, 13, 14, 15, 21, 22, 23, 29, 30 (the background color in the figure is marked as gray), then the segment code sequence corresponding to Pattern 3 is 4, 5, 6, 7, 13, 14, 15, 21, 22, 23, 29, 30. As Figure 5C shown in the coding rules of each text (image), 0 means that the segment code sequence does not appear in the coding data matrix for the grid points with a value of 1 in the pattern matrix of the text, and 1 means that the segment code sequence appears in the coding data matrix for the grid points with a value of 1 in the pattern matrix of the text.

[0097] In the embodiment of the present invention, the passive accessories of the electronic price tag are upgraded to active accessories, eliminating the need for employees to manually replace the accessories, improving the display efficiency of information patterns; at the same time, the hardware circuit of the active accessories is specifically simplified, greatly improving the battery life, and eliminating the need for frequent battery replacement or charging, further improving the display efficiency of information patterns.

[0098] Based on the above embodiment, optionally, the powering the target segment code electrodes of the segment code screen according to the target segment code sequence includes:

[0099] Determine the output pin of the target segment code IC connected to the target segment code electrode corresponding to the target segment code sequence;

[0100] Power the target segment code electrode through the output pin of the target segment code IC.

[0101] Specifically, when designing a segment code screen, the segment code electrodes and the output pins of the segment code IC have been connected one by one. When powering the target segment code electrode subsequently, only according to the connection relationship between the output pins of the segment code IC and the segment code electrodes during the design, determine the target segment code IC output pin connected to the target segment code electrode. Then supply power to the target segment code IC output pin, and the grid points corresponding to the target segment code electrode will be lit, and the target pattern will be displayed on the pattern area of the segment code screen.

[0102] Exemplarily, if you want to display the target pattern 3 on the screen, then according to the target segment code sequence 4, 5, 6, 7, 13, 14, 15, 21, 22, 23, 29, 30 matched by the target pattern 3, refer to Figure 4C Determine the target segment code IC output pins S5, S6, S7, S8, S13, S14, S15, S20, S21, S22, S26, S27 connected to the target segment code electrodes corresponding to the target segment code sequence. Supply power to the segment code electrodes corresponding to the target segment code sequence through these output pins, complete the lighting of the corresponding grid points, and the target pattern 3 can be displayed on the segment code screen.

[0103] Figure 6 The following is a schematic structural diagram of a segment code screen design device provided by another embodiment of the present invention. As Figure 6 shown, the device includes:
