Description

Technical Field

[0001] The present invention relates to a material selection system, and more particularly, to a material selection system capable of screening to select at least one recommended combination of materials suitable for electronic devices, especially display devices. Background Technology

[0002] Materials used in manufacturing display devices can include color-producing materials, light-emitting materials, and spacer materials. Each of these materials has multiple options based on its different optical properties or data values. Therefore, the possible combinations are nearly hundreds of millions. In the past, multiple technicians would select the appropriate material combinations based on product requirements, which was often time-consuming. If product requirements changed or human error occurred, the material selection had to be repeated, rendering all the costs incurred in the previous evaluation process meaningless. Balancing product quality and cost, selecting at least one suitable material combination from so many options is a significant challenge.

[0003] Therefore, there is a real need in the field for improved solutions to assist in recommending material combinations in order to improve the design process of display devices. Summary of the Invention

[0004] The purpose of this invention is to provide a material selection system.

[0005] This invention provides a material selection system for selecting at least one recommended material combination suitable for a display device. The material selection system includes a fully unfolded module, a filtering module, and a package recommendation module. The fully unfolded module lists a plurality of material combinations, including the at least one recommended material combination. The filtering module generates a filtering result from the plurality of material combinations based on a filtering criterion. The package recommendation module generates the at least one recommended material combination based on the filtering result. Attached Figure Description

[0032] Figure 1 This is a schematic diagram of the material selection system 100 in an embodiment. The material selection system 100 can be used to select materials suitable for electronic devices, especially display devices. The material selection system 100 may include a front-end interface input module 105, a specification requirement module 108, and a material matcher 110. The front-end interface input module 105 allows the user to input the required settings. The specification requirement module 108 is coupled to the front-end interface input module 105 and can selectively integrate a local database and / or a cloud database to store and access customer specification requirement data D. The customer specification requirement data D may be related to environmental testing results, material properties, measurement data, etc., but is not limited to these. The material matcher 110 is coupled to the specification requirement module 108 and can be used to output at least one material combination C from a variety of material combinations. By filtering out suitable material combinations, the number of material combinations is reduced, and the design process of the display device is improved. Optionally, the specification requirement module 108 may receive customer specification requirement data D from a database 195 and / or a cloud 198.

[0033] At least one material combination C can be presented to the user through the display unit 120. In addition, the display unit 120 can also be integrated into other output devices to provide the material combination C to other design-related devices and / or users.

[0034] Figure 2A This is a schematic diagram of the material matcher 110 of the material selection system 100 in an embodiment. Figure 2A As shown, the material matching device 110 of the material selection system 100 can be used to select and / or generate at least one recommended material combination C suitable for designing a display device, and the material matching device 110 may include a full-expansion module 112, a screening module 114, and a package recommendation module 119.

[0035] The fully expandable module 112 can be used to list a plurality of material combinations CA, wherein the plurality of material combinations CA may include at least one recommended material combination C generated and recommended by the material selection system 100.

[0036] The first screening module 114 is coupled to the fully expanded module 112 and can be used to generate a first screening result RS1 from a plurality of material combinations according to the first screening conditions.

[0037] The package recommendation module 119 is coupled to the first screening module 114 and can be used to generate at least one recommended material combination C based on the first screening result RS1.

[0038] For example, each material package may include a coloring material, a spacer material, and a luminescent material. The fully unfolded module 112 can be used to generate a plurality of material combinations CA based on the optical data values ​​of a plurality of coloring materials, a plurality of spacer materials, and a plurality of luminescent materials. The material combinations CA described herein may include all possible material combinations; therefore, the number of material combinations CA may be hundreds of millions.

[0039] Figure 2B This is a schematic diagram of the material matcher 110 of the material selection system 100 in another embodiment. (See diagram below.) Figure 2B As shown, the material matching device 110 may include a fully unfolded module 112, a filtering module 114, a first parameter adjustment module 116, an optimal matching module 117, a second parameter adjustment module 118, and a package recommendation module 119.

[0040] Figure 2A and Figure 2B In this context, the screening module 114 can perform a coarse screening operation to reduce the number of material combinations from material combination CA to a smaller number to save time and / or cost. Therefore, the screening module 114 can be a coarse screening module.

[0041] The first parameter adjustment module 116 and the second parameter adjustment module 118 can perform fine screening operations, which can further reduce the number of recommended material combinations. Therefore, the first parameter adjustment module 116 and the second parameter adjustment module 118 can be fine screening modules.

[0042] The optimal matching module 117 can add a correction factor to the coloring material that is adjusted due to the influence of the manufacturing process, and correct the simulated color of the coloring material to reduce the gap between simulation and actual measurement.

[0043] Figure 2B In this embodiment, the second parameter adjustment module 118 can be used selectively. That is, according to the embodiment, Figure 2B The second parameter adjustment module 118 can be optionally omitted, which is also within the scope of the embodiment.

[0044] According to the embodiments, due to process limitations and influences, the thickness difference of coloring materials with different optical colors in the selected material combinations should be less than a predetermined constraint value. In other words, the film thickness of coloring materials with different optical colors should not differ too much, because excessive film thickness differences will reduce product yield or affect product quality. Since red, green, and blue (RGB) coloring materials are mostly used to manufacture display devices, this specification can be referred to as the three-color constraint in this document. In this invention, the material combinations selected at each stage can selectively conform to the three-color constraint specification according to requirements.

[0045] Figure 3 In the example, regarding Figure 1 A schematic diagram of the front-end interface input module 105, specification requirement module 108, and customer specification requirement data D. (See diagram below.) Figure 3 As shown, environmental testing (environmental testing) data for each display product can be collected and stored in the environmental testing results database 310. Environmental testing data may include, but is not limited to, results from high-temperature testing, chemical resistance testing, drop testing, etc. Furthermore, measurement data of various material properties can be collected and stored in the material property database 320. Measurement data of various material properties may include, but is not limited to, various spectral values ​​(e.g., regarding red / green / blue / white / dimming, abbreviated as R / G / B / W / D), transmittance, reflectance, response time, and / or contrast, etc. The above data can be stored in the database via a cloud data storage platform to obtain customer specification requirement data D based on customer specifications obtained from the front-end interface input module 105. Customer specification requirement data D may be related to color rendering index, reliability, optical specifications, electrical specifications, etc. Optionally, data can be stored in the cloud 355 for ease of storage, updating, and retrieval, and for security reasons.

[0046] Figure 4 This is a schematic diagram of the fully deployed module 112 in the embodiment. The fully deployed module 112 may include an environmental testing result database module 1122, a coloring material property database module 1124, a spacer material property database module 1126, a luminescent material property database module 1128, and a machine error correction module 1129. The data in the environmental testing result database module 1122 may correspond to... Figure 3 The environmental testing data. Data from the color-producing material properties database module 1124, the spacer material properties database module 1126, and the luminescent material properties database module 1128 can correspond to... Figure 3 Measurement data from the Material Properties Database 320. Figure 4In this system, the machine error correction module 1129 can adjust and / or compensate the relevant values ​​of the spacer material and / or the light-emitting material according to the machine error value, and adjust the optical data values ​​of multiple material combinations. Therefore, the selected spacer material and / or light-emitting material can be adjusted according to the machine condition for user use.

[0047] Regarding the fully unfolded module 112, for example, if the number of types of red (R) coloring materials is P, the number of types of green (G) coloring materials is Q, the number of types of blue (B) coloring materials is R, the number of types of spacer materials is M, and the number of types of luminescent materials is N, then the fully unfolded module 112 can produce P×Q×R×M×N material combinations. For example, the P×Q×R×M×N material combinations for full unfolding can be... Figure 1 The material combination CA, in this example, can be represented as CA = P × Q × R × M × N. Since the number of material combinations P × Q × R × M × N is too large, the material selection system 100 can perform screening to reduce the number of material combinations and provide more suitable combinations to facilitate the design and manufacturing process. P, Q, R, M, and N can be positive integers greater than zero.

[0048] For example, if the film thickness range of a red coloring material is represented as [1.40, 2.50], where 1.40 is the minimum value and 2.50 is the maximum value, with units in micrometers (µm) and adjustments in increments of 0.01 µm, then [1.40, 2.50] can have 111 different film thicknesses. Similarly, if the film thickness range of a green coloring material is [1.70, 2.80], then there are 111 different film thicknesses; and if the film thickness range of a blue coloring material is [1.60, 2.75], then there are 116 different film thicknesses. In this example, there are 1,429,236 possible combinations of film thicknesses for the red, green, and blue coloring materials, each 111 × 111 × 116. Alternatively, the database may contain 360 possible combinations of red, green, and blue coloring materials, resulting in nearly 520 million material combinations. This sheer number makes it difficult to select suitable combinations. Therefore, the material matching device 110 can quickly and effectively filter and generate suitable combinations. Figure 1 Recommended material combination C.

[0049] Figure 5AThis is a schematic diagram illustrating the processing of spacer materials by the screening module 114 in this embodiment. The screening module 114 can perform reliability verification in the reliability verification operation module 510 to narrow down the types and / or quantities of available spacer materials, thereby reducing the scope. For example, if the product needs to be used in a high-temperature environment, materials that have passed more stringent reliability verification (e.g., high-temperature resistance) can be screened. The screening module 114 may also include a characteristic value comparison module 520 to screen available spacer materials based on predetermined characteristic values. These characteristic values ​​may include, but are not limited to, slant angle, backplane thickness (BP thickness), pixel value thickness (PVthickness), driving voltage, etc. The screening module 114 may also include a characteristic value calculation module 530 to screen available spacer materials based on predetermined calculated values. These calculated values ​​may include, but are not limited to, liquid crystal response time, gray-to-gray value, cell gap, etc. Figure 5A The screening process can select the number of interval materials after screening, for example, m types.

[0050] Figure 5B This is a schematic diagram illustrating the processing of luminescent materials by the screening module 114 in this embodiment. The screening module 114 may include a characteristic value comparison module 522 to screen available luminescent materials based on predetermined characteristic values. These characteristic values ​​may include, but are not limited to, the stack name of the backlight module in the display device, the color point of the light spectrum, etc. The screening module 114 may also include a characteristic value calculation module 532 to screen available luminescent materials based on predetermined calculated values. Figure 5B The selection process can identify the number of selected interval materials, for example, n types. m and n can be positive integers greater than zero, and m ≤ M, n ≤ N.

[0051] Figure 6 This is a schematic diagram illustrating the processing of the coloring material and optical comparison by the screening module 114 in this embodiment. Figure 6As shown, the screening module 114 may include a film thickness adjustment module 610, a color spot screening module 620, and an optical property comparison module 630. The film thickness adjustment module 610 can adjust multiple film thickness ranges of multiple coloring materials according to a threshold (denoted as β) to generate a first result R1. The color spot screening module 620 can generate a second result R2 according to a parameter (denoted as γ) and a set of color spots corresponding to the first result R1. The first screening result RS1 generated by the screening module 114 can be generated based on the second result R2. The optical property comparison module 630 can be selectively set, and the optical property comparison module 630 can generate the first screening result RS1 output by the screening module 114 according to the second result R2 and predetermined optical properties. The following provides a related explanation.

[0052] As mentioned in this invention, adjusting and / or selecting the film thickness of coloring materials (e.g., filter units) is a large and time-consuming process. In the example of this invention, if left unprocessed, it may result in hundreds of millions of material combinations, which is too large. Therefore, the following screening operation can be performed.

[0053] In the film thickness adjustment module 610, assuming the threshold β is 0.2 units (in this example, assuming one unit is micrometer, um), due to process limitations and influences, the difference in film thickness of the red, green and blue (RGB) coloring materials cannot be greater than a predetermined constraint value, such as not being greater than the threshold β (e.g. 0.2 micrometers). Here, the film thickness range of the red, green and blue (RGB) coloring materials can be processed.

[0054] In the example of this invention, the lower limit of the film thickness range of the RGB coloring materials is, for example, 1.40, 1.70, and 1.60 units respectively. Taking the maximum value as 1.7 units, and then subtracting the threshold β (for example, 0.2 units), we get 1.5 units. If the lower limit of the film thickness range of the RGB coloring materials is less than 1.5 units, it can be corrected to 1.5 units. Therefore, the corrected lower limit values ​​of the film thickness range of the RGB coloring materials are 1.50, 1.70, and 1.60 units respectively.

[0055] In the example of this invention, the upper limit of the film thickness range of the RGB coloring materials is, for example, 2.50, 2.80, and 2.75 units respectively, with the minimum value being 2.50 units, plus a threshold β, resulting in 2.70 units. If the upper limit of the film thickness range of the RGB coloring materials is greater than 2.7 units, it can be corrected to 2.7 units. Therefore, the corrected upper limits of the film thickness range of the RGB coloring materials are 2.50, 2.70, and 2.70 units respectively.

[0056] Therefore, the corrected film thickness ranges for the RGB coloring materials can be [1.50, 2.50], [1.70, 2.70], and [1.60, 2.70], respectively. If the minimum adjustment unit is 0.01 units, the number of corrected film thicknesses for the RGB coloring materials can be 101, 101, and 111, respectively. Therefore, the number of combinations can be 101 × 101 × 111, which is 1,132,311. Thus, the number of film thickness combinations can be reduced from 1,429,236 to 1,132,311, a reduction of approximately 21%, achieving the desired screening effect.

[0057] Regarding the color dot screening module 620 and parameter γ, when the material package of the first result R1 has multiple film thickness combinations of coloring materials, it is possible to check whether the corresponding simulated color dots are within the required range in order to further screen suitable film thickness ranges.

[0058] Assuming the customer's required color point value is set as CV, and the predetermined error value is set as ε, then the range can be obtained as: CV±γ×ε, that is, the range from (CV-γ×ε) to (CV+γ×ε), with CV as the center point of this range.

[0059] In the first result R1, if the simulated color point does not fall within the aforementioned range (i.e., the range from (CV-γ×ε) to (CV+γ×ε)), it can be excluded from selection. For example, this operation can reduce the number of combinations of RGB coloring materials by approximately 80%. The aforementioned predetermined error value ε can be selected based on statistics, experience, and / or measurement results to determine an appropriate error value. The aforementioned parameter γ can be, for example, 3, or a suitable parameter. The aforementioned color point can be, for example, a simulated color point of red, green, blue, and white (RGBW), or referred to as simulated chromaticity.

[0060] Regarding the optical characteristics module 630, it can generate a first screening result RS1 for the screening module 114 based on the second result R2 and the predetermined optical characteristics. The predetermined optical characteristics may include, but are not limited to, NTSC (National Television Standards Committee) color characteristics and coverage. These optical characteristics should meet the minimum threshold requirements of customers and users, and only material combinations that meet the requirements can be included in the first screening result RS1. In this way, more suitable material combinations can be selected.

[0061] Figure 7 This is a schematic diagram of the first parameter adjustment module 116 in the embodiment. The first parameter adjustment module 116 can generate a first adjustment result RA1 based on a threshold (denoted as α*), a parameter (denoted as γ*), and a first screening result RS1 generated by the screening module 114. The first adjustment result RA1 can be used to generate a recommended material combination C. For example... Figure 7As shown, the first parameter adjustment module 116 may include a film thickness adjustment module 710, a color point screening module 720, and an optical property comparison module 730.

[0062] Regarding the film thickness adjustment module 710, it can process the multiple film thickness ranges of multiple coloring materials corresponding to the first screening result RS1 according to the threshold α*, so as to generate a multiple array of first discrete film thickness values.

[0063] For example, this invention mentions that after the coarse sieving operation of the screening module 114, the corrected film thickness ranges of the red, green, and blue (RGB) coloring materials can be [1.50, 2.50], [1.70, 2.70], and [1.60, 2.70], respectively, and the unit can be micrometers (µm). Taking a threshold α* of 0.1 µm as an example, after using the threshold α* for segmentation, the red, green, and blue (RGB) coloring materials can correspond to the following discrete film thickness values: the film thickness of the red (R) coloring material can be [1.50, 1.60, 1.70, ... 2.50]; the film thickness of the green (G) coloring material can be [1.70, 1.80, 1.90, ..., 2.70]; and the film thickness of the blue (B) coloring material can be [1.60, 1.70, 1.80, ..., 2.70]. Here, various combinations of fully expanded values ​​can be generated based on the discrete values ​​of the film thickness of the red, green, and blue (RGB) coloring materials. The film thickness adjustment module 710 can also exclude unsuitable material combinations according to the three-color constraint. For example, according to the three-color constraint, the difference in film thickness between any two colors cannot exceed a threshold β* (for example, the threshold β* can be 2 micrometers). In this example, since there are 11 discrete values ​​for the red (R) film thickness, 11 discrete values ​​for the green (G) film thickness, and 12 discrete values ​​for the blue (B) film thickness, the number of material combinations to consider can be reduced to 11 × 11 × 12, or 1,452 material combinations, which is a significant reduction compared to the more than one million material combinations mentioned above. The numbers in this article are for illustrative purposes only, and the embodiments are not limited thereto.

[0064] After processing by the film thickness adjustment module 710, since the film thickness of the three coloring materials has been listed in a discrete manner, the number of material combinations can be greatly reduced.

[0065] After obtaining the discrete values ​​of the film thickness of the coloring material produced by the film thickness adjustment module 710, the color point screening module 720 can perform similar operations. Figure 6 The operation of the color point screening module 620 compares the simulated color points corresponding to the material combination with a predetermined range, and excludes material combinations whose simulated color points fall outside the predetermined range, so as to further select suitable material combinations and remove unsuitable material combinations.

[0066] The permissible range of color points corresponding to the color point filtering module 720 can be expressed as CV±γ*×ε*, that is, the range from (CV–γ*×ε*) to (CV+γ*×ε*), where CV can be the color point value required by the customer, the parameter γ* can be a suitable predetermined value, and ε* can be a suitable error value.

[0067] Compared with the parameter γ and error value ε of the screening module 114 mentioned above, the parameter γ* can be less than or equal to the parameter γ (expressed as γ*≤γ), and the error value ε* can be less than or equal to ε (expressed as ε*≤ε). In other words, the screening conditions used in the fine screening operation of the first parameter adjustment module 116 can be more stringent than the screening conditions in the coarse screening operation of the screening module 114.

[0068] Regarding the optical characteristics module 730, it can generate a first adjustment result RA1 based on the results of the color dot screening module 720 and predetermined optical characteristics. The predetermined optical characteristics may include, but are not limited to, NTSC color characteristics and coverage. These optical characteristics should meet the customer's minimum threshold requirements. Only material combinations that meet the requirements can be selected into the first adjustment result RA1, thereby allowing for the selection of more suitable material combinations.

[0069] Selectively, such as Figure 7 As shown, the sorting module 740 can be set and used to perform sorting operations using a predetermined algorithm to further select at least one more suitable combination of materials.

[0070] Figure 8 This is a schematic diagram of the optimal matching module 117 in the embodiment. The optimal matching module 117 may include a film thickness comparison module 810 and a sorting module 820. The film thickness comparison module 810 can generate at least one suitable set of correction factors based on the photoresist value and / or film thickness value of the coloring material in the material combination of the first adjustment result RA1, so that the selected material has a better display effect. The correction factors may be related to a set of photoresist factors, a set of photomask factors, and / or a set of film thickness factors.

[0071] Figure 8 In this module, the sorting module 820 can be used to sort and select correction factors. When the correction factors generated by the film thickness comparison module 810 do not exceed X sets of correction factors, all correction factors can be used to generate the matching result RM1. However, when the correction factors generated by the film thickness comparison module 810 exceed X sets of correction factors, a sorting operation can be performed to select Y sets of correction factors, which can then be used to generate the matching result RM1. Here, X and Y can be predetermined positive integers greater than 0.

[0072] This invention uses X=2 and Y=1 as an example. If the film thickness comparison module 810 generates two sets of correction factors based on the coloring material of the material combination in the first adjustment result RA1, since the two sets of correction factors do not exceed X sets of correction factors (X=2), both sets of correction factors can be used to generate the matching result RM1. If the film thickness comparison module 810 generates three sets of correction factors based on the coloring material of the material combination in the first adjustment result RA1, since the three sets of correction factors exceed X sets of correction factors (X=2), the sorting module 820 can perform sorting to select one set of correction factors (Y=1) to generate the matching result RM1. The values ​​of X and Y here are examples and can be adjusted according to requirements.

[0073] Figure 9 This is a schematic diagram of the second parameter adjustment module 118 in the embodiment. The second parameter adjustment module 118 can be used selectively. That is, if the material combination corresponding to the matching result RM1 generated by the optimal matching module 117 already meets the requirements, the second parameter adjustment module 118 can be selectively not used. If, after generating the matching result RM1, it is necessary to further select a suitable material combination, then the second parameter adjustment module 118 can be used.

[0074] The second parameter adjustment module 118 may include a film thickness adjustment module 910, a color point screening module 920, and a characteristic comparison module 930. Optionally, it may also include a sorting module 940. The second parameter adjustment module 118 may further select a more suitable material combination based on the threshold α**, threshold β**, parameter γ**, and matching result RM1 to generate a second adjustment result RA2, as described below.

[0075] In the film thickness adjustment module 910, the center film thickness of the coloring material in the first screening result RS1 generated by the screening module 114 can be processed. The center film thickness mentioned here can be the center film thickness within a certain film thickness range. For example, if the film thickness range is A micrometers to B micrometers, then the center film thickness can be [(A+B) / 2] micrometers.

[0076] The following example illustrates this. Assume the center film thicknesses of the red, green, and blue (RGB) coloring materials in the first screening result RS1 are 1.70 μm, 1.80 μm, and 1.90 μm, respectively. The adjusted ranges can be obtained using a threshold β**. For example, assuming a threshold β** of 0.1 μm, the adjusted range for the red (R) coloring material would be 1.70 ± 0.1 μm, or 1.60–1.80 μm; the adjusted range for the green (G) coloring material would be 1.80 ± 0.1 μm, or 1.70–1.90 μm; and the adjusted range for the blue (B) coloring material would be 1.90 ± 0.1 μm, or 1.80–2.00 μm.

[0077] Then, a threshold α** can be used to obtain the discrete film thickness values ​​of the coloring materials for each color. For example, assuming the threshold α** is 0.02 micrometers, the discrete film thickness values ​​of the red (R) coloring material can be 1.60, 1.62, 1.64…1.80 micrometers, a total of 11 discrete film thickness values. The discrete film thickness values ​​of the green (G) coloring material can be 1.70, 1.72, 1.74…1.90 micrometers, a total of 11 discrete film thickness values. The discrete film thickness values ​​of the blue (B) coloring material can be 1.80, 1.82, 1.84…2.00 micrometers, a total of 11 discrete film thickness values. In this example, there are 1,331 possible combinations of discrete film thickness values ​​for the red, green, and blue (RGB) coloring materials. The above figures are for illustrative purposes only, and the embodiments are not limited to these.

[0078] Regarding the color point filtering module 920, similar to the color point filtering modules 620 and 720 mentioned above, the allowable color point range corresponding to the color point filtering module 920 can be expressed as CV±γ**×ε**, that is, the range from (CV–γ**×ε**) to (CV+γ**×ε**), where CV can be the color point value required by the customer, the parameter γ** can be a suitable predetermined value, and ε** can be a suitable error value.

[0079] Compared with the parameter γ and error value ε of the screening module 114 mentioned above, the parameter γ* can be less than or equal to the parameter γ (expressed as γ**≤γ), and the error value ε** can be less than or equal to ε (expressed as ε**≤ε). In other words, the screening conditions used in the fine screening operation of the second parameter adjustment module 118 can be more stringent than the screening conditions in the coarse screening operation of the screening module 114.

[0080] Selectively, the threshold α** used in the second parameter adjustment module 118 may be less than or equal to the threshold α* used in the first parameter adjustment module 116 (expressed as α**≤α*). The parameter γ** used in the second parameter adjustment module 118 may be less than or equal to the parameter γ* used in the parameter adjustment module 116 (expressed as γ**≤γ*). In other words, selectively, the filtering conditions used in the second parameter adjustment module 118 may be more stringent than the filtering conditions used in the first parameter adjustment module 116.

[0081] Selectively, such as Figure 9 As shown, the sorting module 940 can be set and used to perform sorting operations using a predetermined algorithm to further select at least one more suitable combination of materials.

[0082] Figure 10This is a schematic diagram illustrating the detection and sorting operation performed by the package recommendation module 119 in this embodiment. The package recommendation module 119 can generate a recommended material combination C based on the first screening result RS1, the matching result RM1, and / or the second adjustment result RA2. The package recommendation module 119 can perform a detection and sorting operation to adjust and generate the combination. The package recommendation module 119 may include a detection module 1010 and a sorting module 1020. The detection module 1010 can perform a detection and sorting operation on new material characteristics, unique material characteristics, dissimilar material characteristics, and / or difficult material characteristics of the material combination to generate a detection and sorting result RD1.

[0083] The detection performed by the detection module 1010 can be considered negative detection or "deduction" detection. If a material combination uses new materials not previously used, unique materials rarely used in other processes and by suppliers, dissimilar materials different from commonly used materials, and / or difficult materials that are more challenging to use, then this material combination can be marked to deduct points from its score, thereby reducing its preference. Due to the above detection methods, the detection of new, unique, dissimilar, and / or difficult materials by the detection module 1010 can be called NUDD detection.

[0084] The sorting module 1020 can adjust the sorting of material combinations based on the detection results of the detection module 1010, and sort the material combinations that have been deducted more points to the end, so as to make them less priority, in order to help select more suitable material combinations.

[0085] Figure 11 This is a schematic diagram illustrating the package recommendation module 119 performing a product contrast assessment operation and / or a product transmittance assessment operation in this embodiment. Figure 11 As shown, the package recommendation module 119 may further include a product contrast database 1110, a product contrast evaluation module 1115, a product transmittance database 1120, and a product transmittance evaluation module 1125.

[0086] Package recommendation module 119 is available. Figure 10 The detection and sorting result RD1, along with the material combination and the data from the product contrast database 1110, are used in the product contrast evaluation module 1115 to perform a product contrast evaluation operation.

[0087] In addition, the recommended package module 119 is available. Figure 10 The detection and sorting result RD1, along with the material combination and the data from the product penetration rate database 1120, are used to perform a product penetration rate evaluation operation in the product penetration rate evaluation module 1125.

[0088] pass Figure 11 Our product contrast evaluation and product transmittance evaluation operations ensure that the selected recommended material combination C meets the customer's requirements for product contrast and transmittance.

[0089] According to the embodiment, the recommended material combination C can be synchronously written into the database for storage. Additionally, the entire framework is uploaded to a cloud server computing platform using suitable virtualization container technology (e.g., Docker). Through application programming interface (API) technology, users can access the model via a front-end webpage, allowing execution and visualization of the corresponding recommended material combinations in charts for easy viewing.

[0090] According to embodiments, the sorting operation mentioned in this invention can be performed using Euclidean distance, Mahalanobis distance, Manhattan distance, or other suitable methods.

[0091] In conclusion, the material selection system can effectively filter out unsuitable material combinations, significantly reducing the number of recommended material combinations. This allows for faster design and manufacturing processes and effectively reduces error rates and related time, manpower, and material costs. Therefore, it is truly helpful in addressing engineering challenges in this field.

Various modifications and variations can be made to the present invention by those skilled in the art.
