detailed description

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The present invention provides a method for selecting a test screen. Referring to FIG. 1, in the first embodiment, the method for selecting a test screen includes the following steps:

Step S10: Obtain performance parameters of all types of screens to be tested, set a set of performance parameters of each type of screen to be tested as a parameter subset, and set a set of performance parameters of all types of screens to be tested as a total set of parameters;

This embodiment provides a method for selecting a test screen. At present, smart TVs on the market mainly have two kinds of displays, namely LCD and LED display screens, and LCD and LED display screens have many types, which are usually the same in order to meet the needs of different users. Smart TVs are compatible with different types of LCD and LED displays. After the software upgrade of the smart TV, in order to ensure that the different types of LCD and LED display compatible with the smart TV before the software upgrade can continue to be used, it is necessary to perform compatible different types of LCD and LED display on the basis of the upgraded software. Test, the LCD and LED display that need to be tested is the screen to be tested. Obtain performance parameters of all types of screens to be tested, including performance timing of the screen, resolution, whether 3D is supported, etc., and a set of performance parameters of each type of screen to be tested is used as a parameter subset, and all types are to be The set of performance parameter combinations of the test screen is taken as the total set of parameters, and the number of the parameter subsets is consistent with the number of all types of screens to be tested.

Step S20: Acquire all test cost parameters corresponding to the parameter to be tested corresponding to the parameter sub-set;

In this embodiment, the test cost of a single screen to be tested is the cost that is required in the process of testing a certain screen, and the cost of the test is related to the market usage of the screen, the extensive performance of the screen, and the acquisition cost of the screen. Understandably, the usage of different types of screens in the market is definitely different, the performance parameters are also inconsistent, and it is not possible to easily obtain screens of all models during testing, resulting in different test cost parameters for different test screens. For each factor that affects the cost of the test, the test cost is expressed by the test cost parameter. The test cost parameter of the test screen corresponding to the parameter subset is obtained, so that the test screen with lower test cost is selected according to the test cost parameter.

Step S30: Obtain an intersection parameter quantity of the intersection performance parameter of each parameter subset and the parameter total set, and obtain a ratio of the intersection parameter quantity of each parameter subset and the corresponding test cost parameter;

It can be understood that the performance parameters of different types of screens are inconsistent, resulting in inconsistent parameter subsets of performance parameters of each type of screen to be tested. By calculating the intersection of each parameter subset and the total parameter set, the number of intersection parameters of the performance parameters of the intersection is obtained, thereby determining the distribution of the performance parameter number of each screen to be tested in the performance parameter quantity of all the screens to be tested, and the selection performance is convenient. The screen with the widest coverage of parameters is tested. In a specific embodiment, the A screen is an upgrade of the B screen, the A screen basically supports 3D, and the B model does not support 3D, and other parameters are consistent, and the 3D is included in the parameter subset of the A screen. Performance parameters, while the B screen does not include performance parameters that support 3D. For the total set of parameters including the performance parameters of all the screens to be tested, the performance parameters supporting 3D are definitely included, so the parameter subsets and parameters of the A screen are included. The number of performance parameters obtained by the intersection of the total set is one more than the number of performance parameters obtained by intersecting the parameter subset and the parameter total set of the B screen. When the other parameters are the same, the A screen is selected as the test screen to cover the B screen. Testing reduces the workload. However, considering the test cost parameters comprehensively, the market usage of the A screen is very low, and it is inconvenient to obtain the A screen, and it is necessary to re-purchase and adjust the goods, and the procurement logistics cost is high. The B screen has a high market usage and has existing inventory. At this time, selecting the A screen as the test screen is not necessarily more reasonable than selecting the B screen as the test screen. It is necessary to reasonably balance the relationship between the number of intersection parameters of each parameter subset and the corresponding test cost parameter to determine which screen to select as the screen to be tested. Specifically, by calculating the ratio of the number of intersection parameters of each parameter subset to the corresponding test cost parameter, the ratios obtained by different types of screens are inconsistent, and are related to the performance parameters of the screen to be tested and the test cost parameters.

Step S40: Select a target test screen from all types of screens to be tested according to the ratio, wherein the larger the ratio, the higher the selection priority.

In the technical solution of the present invention, the ratio is divided by the number of intersection parameters of each parameter subset by the corresponding test cost parameter, and according to the ratio, the corresponding parameter subset can be determined, and then the corresponding to the parameter subset is determined. Screen, this screen is the target test screen. The larger the ratio, the more the number of intersection parameters of each parameter subset is, that is, the number of performance parameters of the screen to be tested accounts for a large proportion of the performance parameters of all the screens to be tested, or the smaller the test cost parameter. The screen to be tested corresponding to the larger ratio is preferentially selected as the target test screen for testing, so that the test coverage is optimally compared with the test cost.

The method for selecting a test screen of the embodiment includes the following steps: acquiring performance parameters of all types of screens to be tested, using a set of performance parameters of each type of screen to be tested as a parameter subset, and composing performance parameters of all types of screens to be tested. The set is used as a total set of parameters; the test cost parameters corresponding to the screen to be tested corresponding to the parameter subset are obtained; the number of intersection parameters of the intersection performance parameters of each parameter subset and the parameter total set is obtained, and the intersection parameters of each parameter subset are obtained. The ratio of the quantity to the corresponding test cost parameter; according to the ratio, the target test screen is selected from all types of screens to be tested, wherein the larger the ratio, the higher the pick priority. In this solution, the performance parameters of each type of the screen to be tested are combined into a parameter subset, and the performance parameters of all types of the screen to be tested are combined into a total set of parameters, and each parameter subset is intersected with the total set of parameters. The number of intersection parameters of the intersection performance parameter is divided by the test cost parameter of the corresponding test panel of the parameter subset, and the screen to be tested corresponding to the larger ratio is preferentially selected as the target test screen. The larger the ratio, the more the intersection is explained. The number of intersection parameters of the performance parameters includes many performance parameters, that is, the performance parameters of the screen to be tested corresponding to the parameter subset are more, and the number of screens that can be covered as the target test screen is selected; on the other hand, the test cost parameter is described. Low, the user is more likely to select this screen, and select it as the target test screen to suit the market demand. Therefore, according to the larger ratio, the higher the priority rule, the higher the compatibility and the higher market usage rate of the screen can be tested, avoiding the time-consuming and laborious test of the screen-one test, and the incompleteness of the subjective screen test.

In a specific embodiment, when there are n models of the screen to be tested, the performance parameters of the n screens to be tested are obtained, and the parameter subsets S1, S2, ..., ... of the single screen to be tested are formed (i is less than n) Value) and the total set of parameters E including all the screens to be tested; according to the market usage, the extensiveness of the screen performance parameters and the convenience of obtaining the screen, etc., determine the test cost parameter Wi of the i-th screen; for the i-th According to the parameter subset Si and the test cost parameter Wi including its performance parameters, the number of intersection performance parameters and the test cost of the parameter sub-set and the parameter total set of the i-th screen can be obtained by |Si∩E|/Wi For the ratio of the parameters, select the i-th screen with the largest ratio as the target test screen. To assist understanding, the specific embodiment is described. There are 120 screens to be tested. The performance parameters of the first screen to be tested are a, b, and c. The performance parameters of the second screen to be tested are g, f, and the ninth screen to be tested. The performance parameters are q, w, e, r; then S1 = {a, b, c}, S2 = {g, f}... S9 = {q, w, e, r}, E = {a, b, c, g, f...q, w, e, r...}; the test cost parameter of the first screen to be tested is W1=1.2, and the test cost parameter of the second screen to be tested is W2=1, ninth The test cost parameter of the hospitality test screen is W9=1.8; then |S1∩E|/W1=3/1.2=2.5,|S2∩E|/W2=2/1=2,|S9∩E|/W9=4/ 1.8=2.2; The calculation result shows that the ratio of the first screen to be tested is the largest, the ratio of the screen to be tested is the second, and the ratio of the screen to be tested is the smallest. Therefore, the first test screen to be tested is preferentially selected as the target test screen, and secondly, the ninth test screen to be tested and the second test screen to be tested are selected as the target test screen. By preferentially selecting the screen to be tested corresponding to the larger ratio as the target test screen, the test of the selected part of the target test screen can be covered to cover all types of test screens to be tested, thereby reducing the test workload.

Further, in another embodiment of the method for selecting a test screen of the present invention, step S40 includes:

Step S41, comparing the relationship between the number of intersection parameters of the respective parameter subsets and the ratio of the corresponding test cost parameters, and determining a maximum ratio;

Step S42, determining, according to the maximum ratio, a parameter subset corresponding to the maximum ratio;

Step S43, selecting a target test screen corresponding to the parameter subset according to the parameter subset.

Specifically, the performance parameters included in different types of screens are inconsistent, resulting in inconsistent parameter subsets of performance parameters of each type of screen to be tested, thereby dividing the number of intersection parameters of the performance parameters of the parameter subsets and the total parameters of the parameters. The ratios obtained from the corresponding test cost parameters are also inconsistent. The ratios are compared to determine the maximum ratio. According to the determined maximum ratio, the parameter subset corresponding to the maximum ratio can be determined, and then the screen to be tested corresponding to the parameter subset is determined, and the screen is the target test screen. In a specific embodiment, the types of screens to be tested are A, B, and C. The performance parameters of the A screen are p, o, and i, and the performance parameters of the B screen are k, j, and C screens. The performance parameters are j, i, n, m, then the parameter subsets are Sa={p, o, i}, Sb={k, j}, Sc={j, i, n, m}, the total set of parameters It is E={p, o, i, k, j, n, m}. The test cost parameters of the three panels A, B and C are 1, 0.8 and 1.2 respectively, then the ratios are |Sa∩E|/Wa=3/1=3, |Sb∩E|/Wb=2/ 0.8=2.5, |Sc∩E|/Wc=4/1.2=3.3. Comparing the ratio of the ratios of the three panels A, B and C, it can be seen that the ratio obtained by |Sc∩E|/Wc is the largest, and the corresponding parameter subset Sc can be determined according to the maximum ratio, according to the performance in the parameter subset Sc The parameter determines that the C screen is corresponding to this performance parameter, thereby determining that the C screen is the target test screen. Therefore, according to the maximum ratio, the corresponding test screen is selected as the target test screen, so that the test coverage and the test cost are optimally matched.

Further, referring to FIG. 2, based on the first embodiment of the method for selecting a test screen of the present invention, a second embodiment for selecting a test screen is proposed. In the second embodiment, after the step S40, the step S40 is further included. step:

Step S50, controlling to remove performance parameters of the target test screen included in the total set of parameters;

Step S60, determining whether at least one performance parameter is included in the total parameter set;

Step S70, if yes, performing the steps of obtaining the intersection parameter quantity of the intersection performance parameter of each parameter subset and the parameter total set, and obtaining the ratio of the intersection parameter quantity of each parameter subset and the corresponding test cost parameter.

In the solution of the embodiment, the performance parameters common to the parameter set and the parameter subset of the target test screen are removed, and it is determined whether the total parameter set after the common performance parameter is removed further includes the performance parameter, and if Performance parameters, indicating that the selected target test screen can not cover all the screens that need to be tested, and it is necessary to continue to select the test screen. The loop execution line obtains the number of intersection parameters of the intersection performance parameters of each parameter subset and the parameter total set, and obtains the ratio of the intersection parameter quantity of each parameter subset to the corresponding test cost parameter; and controls to remove the target included in the parameter total set The steps to test the performance parameters of the screen. Until the parameter total set does not contain any performance parameters, it is an empty set, and all the parameter sub-sets corresponding to all the maximum ratios obtained in the loop process are composed into a target set, and the screen to be tested corresponding to all the parameter subsets in the target set is all Target test screen. Specifically, in the n screens to be tested, the i-th (i≤n) screen is selected as the target test screen, and the corresponding parameter subset is merged into the initial set of the target set C, that is, C=( C∪Si), at the same time E=E-Si, judge whether E contains performance parameters, and if so, continue to execute |Si∩E|/Wi to select the target test screen until E does not contain performance parameters, then target set C The screen to be tested corresponding to all the parameter subsets in the middle is all target test screens, and all the test screens can be covered by testing all the target test screens, thereby reducing the test cost and workload.

Further, the step of obtaining all the test cost parameters of the screen to be tested corresponding to the parameter subset by step S20 includes:

Step S21: Obtain a market usage amount, an inventory quantity, and a performance parameter quantity of the screen to be tested corresponding to the parameter subset;

Step S22: Acquire a test cost parameter corresponding to the market usage amount, the inventory quantity, and the performance parameter quantity to be tested.

Specifically, the test cost of a single screen to be tested is the cost involved in testing a certain screen, and thus the lower the test cost of a certain screen, the higher the priority test. The specific test cost is related to factors such as the market usage of the screen, the extensive performance of the screen, and the acquisition cost of the screen. When the market usage of a certain screen is larger, the screen can be tested to achieve the most use of the test, that is, the lower the test cost; when a screen contains several screen functions, the screen can be tested to cover it. The test of several screens included, the test cost is low; when a certain screen has inventory, the test only needs to be extracted from the warehouse, and there is no need to re-purchase the transportation and the like, that is, the low screen acquisition cost is also defined as the low test cost. Combine the factors that affect the cost of the test, and use the test cost parameter to express the test cost. Understandably, the test cost parameter is related to the influence of various influencing factors on the test cost, that is, one of the influencing factors has a great influence on the test cost, and other items have less influence on the test cost, indicating that the influencing factor It has a great influence on the test cost and plays a key role in determining the test cost parameter. In a specific embodiment, there are two screens to be tested, A and B, and the number of performance parameters is the same, wherein the market for the A-test screen is large, accounting for 80% of the market share, but the warehouse has no inventory, and the market for the B-test screen is B. The amount of use is small, accounting for 8% of the market share, but in stock. At this time, for the A screen, the test cost factor affecting the test cost parameter is the market usage, and for the B screen, the test cost factor affecting the test cost parameter is the inventory quantity. According to the obtained market usage amount, inventory quantity and performance parameter quantity of the single screen to be tested, the test cost parameter of the single screen to be tested can be determined, and the test screen with lower test cost can be selected according to the test cost parameter.

Preferably, step S10 acquires performance parameters of all types of screens to be tested, and sets a set of performance parameters of each type of screen to be tested as a parameter subset, and sets a set of performance parameters of all types of screens to be tested as a total set of parameters. include:

Step S11, determining the model of all types of screens to be tested;

Step S12, obtaining performance parameters of each type of screen to be tested in all types of screen models to be tested;

Step S13, grouping performance parameters of each type of screen to be tested, and using the set as a parameter subset;

Step S14, controlling to remove the duplicate parameter of the performance parameter of each type of the screen to be tested in all types of screens to be tested, composing a performance parameter set including all types of screens to be tested, and using this set as a total set of parameters.

Understandably, the smart TV supports multiple types of screens, and the types of screens are different, and the performance parameters thereof are necessarily different. According to all types of screens supported by the smart TV, the models of all types of screens to be tested are determined, and each type of screen to be tested is obtained. Corresponding performance parameters, on the one hand, combine the corresponding performance parameters of each type of the screen to be tested into corresponding parameter subsets of the respective screens to be tested, and on the other hand, control to remove the duplicates in the corresponding performance parameters of each type of the screen to be tested. , combined into a total set of parameters containing performance parameters for all types of screens to be tested. In a specific embodiment, when the performance parameters of the E-to-test screen are p, o, and h, and the performance parameters of the F-to-test screen are p, k, and v, the parameter subsets are Se={p, o, respectively. h}, Sf={p, k, v}, the total set of parameters is the set {p, o, h, k, v} after removing a duplicate p, wherein the number of parameter subsets and the screen to be tested The number is the same.

The present invention also provides a screen device for selecting a test. Referring to FIG. 3, in the first embodiment, the screen device for selecting a test provided by the present invention includes:

The first obtaining module 10 is configured to obtain performance parameters of all types of screens to be tested, and set a set of performance parameters of each type of screen to be tested as a parameter subset, and set a set of performance parameters of all types of screens to be tested as a parameter total. set;

This embodiment provides a screen device for selecting tests. Currently, smart TVs on the market mainly have two kinds of displays, namely LCD and LED display screens, and LCD and LED display screens have many types, and the same type is usually used to meet the needs of different users. Smart TVs are compatible with different types of LCD and LED displays. After the software upgrade of the smart TV, in order to ensure that the different types of LCD and LED display compatible with the smart TV before the software upgrade can continue to be used, it is necessary to perform compatible different types of LCD and LED display on the basis of the upgraded software. Test, the LCD and LED display that need to be tested is the screen to be tested. The first obtaining module 10 obtains performance parameters of all types of screens to be tested, including the power-on sequence of the screen, the resolution, whether 3D is supported, and the like, and the set of performance parameters of each type of the screen to be tested is used as a parameter subset. A set of performance parameter combinations of all types of screens to be tested is taken as a total set of parameters, and the number of parameter subsets thereof is consistent with the number of all types of screens to be tested.

The second obtaining module 20 is configured to obtain all test cost parameters corresponding to the parameter to be tested corresponding to the parameter subset;

In this embodiment, the test cost of a single screen to be tested is the cost that is required in the process of testing a certain screen, and the cost of the test is related to the market usage of the screen, the extensive performance of the screen, and the acquisition cost of the screen. Understandably, the usage of different types of screens in the market is definitely different, the performance parameters are also inconsistent, and it is not possible to easily obtain screens of all models during testing, resulting in different test cost parameters for different test screens. For each factor that affects the cost of the test, the test cost is expressed by the test cost parameter. The second obtaining module 20 obtains a test cost parameter of the test screen corresponding to the parameter subset, so as to select a test screen with a lower test cost according to the test cost parameter.

The third obtaining module 30 is configured to obtain an intersection parameter quantity of the intersection performance parameter of each parameter subset and the parameter total set, and obtain a ratio of the intersection parameter quantity of each parameter subset and the corresponding test cost parameter;

It can be understood that the performance parameters of different types of screens are inconsistent, resulting in inconsistent parameter subsets of performance parameters of each type of screen to be tested. The third acquisition module 30 calculates the intersection of each parameter subset and the total parameter set, and obtains the intersection parameter quantity of the performance parameter of the intersection, thereby determining the distribution of the performance parameter quantity of each screen to be tested in the performance parameter quantity of all the screens to be tested. In this case, it is convenient to select the screen with the widest coverage of performance parameters for testing. In a specific embodiment, the A screen is an upgrade of the B screen, the A screen basically supports 3D, and the B model does not support 3D, and other parameters are consistent, and the 3D is included in the parameter subset of the A screen. Performance parameters, while the B screen does not include performance parameters that support 3D. For the total set of parameters including the performance parameters of all the screens to be tested, the performance parameters supporting 3D are definitely included, so the parameter subsets and parameters of the A screen are included. The number of performance parameters obtained by the intersection of the total set is one more than the number of performance parameters obtained by intersecting the parameter subset and the parameter total set of the B screen. When the other parameters are the same, the A screen is selected as the test screen to cover the B screen. Testing reduces the workload. However, considering the test cost parameters comprehensively, the market usage of the A screen is very low, and it is inconvenient to obtain the A screen, and it is necessary to re-purchase and adjust the goods, and the procurement logistics cost is high. The B screen has a high market usage and has existing inventory. At this time, selecting the A screen as the test screen is not necessarily more reasonable than selecting the B screen as the test screen. It is necessary to reasonably balance the relationship between the number of intersection parameters of each parameter subset and the corresponding test cost parameter to determine which screen to select as the screen to be tested. Specifically, the third acquisition module 30 calculates the ratio of the number of intersection parameters of each parameter subset to the corresponding test cost parameter, and determines that the ratios obtained by different types of screens are inconsistent, and are related to the performance parameters of the screen to be tested and the test cost parameters. .

The selecting module 40 is configured to select a target test screen from all types of screens to be tested according to the ratio, wherein the larger the ratio, the higher the picking priority.

In the technical solution of the present invention, the ratio is divided by the number of intersection parameters of each parameter subset by the corresponding test cost parameter, and according to the ratio, the corresponding parameter subset can be determined, and then the corresponding to the parameter subset is determined. Screen, this screen is the target test screen. The larger the ratio, the more the number of intersection parameters of each parameter subset is, that is, the number of performance parameters of the screen to be tested accounts for a large proportion of the performance parameters of all the screens to be tested, or the smaller the test cost parameter. The selection module 40 preferentially selects the screen to be tested corresponding to the larger ratio as the target test screen, so that the test coverage and the test cost are optimally matched.

The device for selecting test screens of the present embodiment includes: a first obtaining module 10, configured to acquire performance parameters of all types of screens to be tested, and set a set of performance parameters of each type of screen to be tested as a parameter subset, and all types are to be The set of performance parameters of the test screen is used as a total set of parameters; the second obtaining module 20 is configured to obtain all test cost parameters corresponding to the screen to be tested corresponding to the parameter subset; and the third obtaining module 30 is configured to obtain each parameter subset and The number of intersection parameters of the performance parameters of the total set of parameters, and the ratio of the number of intersection parameters of each parameter subset to the corresponding test cost parameter; the selection module 40 is configured to select from all types of screens to be tested according to the ratio The target test screen is out, wherein the larger the ratio, the higher the pick priority. In this solution, the performance parameters of each type of the screen to be tested are combined into a parameter subset, and the performance parameters of all types of the screen to be tested are combined into a total set of parameters, and each parameter subset is intersected with the total set of parameters. The number of intersection parameters of the intersection performance parameter is divided by the test cost parameter of the corresponding test panel of the parameter subset, and the screen to be tested corresponding to the larger ratio is preferentially selected as the target test screen. The larger the ratio, the more the intersection is explained. The number of intersection parameters of the performance parameters includes many performance parameters, that is, the performance parameters of the screen to be tested corresponding to the parameter subset are more, and the number of screens that can be covered as the target test screen is selected; on the other hand, the test cost parameter is described. Low, the user is more likely to select this screen, and select it as the target test screen to suit the market demand.
