Detailed Description
In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.
Certain terms are used throughout the description and following claims to refer to particular components. As one of ordinary skill in the art will appreciate, manufacturers may refer to a component by different names. The present specification and claims do not intend to distinguish between components that differ in name but not function. In the following description and in the claims, the terms "include" and "comprise" are used in an open-ended fashion, and thus should be interpreted to mean "include, but not limited to.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic flow chart of a testing method according to an embodiment of the invention; fig. 2 is a system block diagram of a test system according to an embodiment of the present invention.
As shown in fig. 1, the present invention provides a testing method for a display module, including:
step S100, the processing module 100 obtains a limit value of color coordinates and a limit value of brightness in the display module.
In this embodiment, the display module may be a display module in a monitor, an intelligent television, a personal computer or other display devices, and the invention is not limited thereto. The basic hardware environment of the display module at least comprises a display panel and a backlight module, wherein the display panel is preferably a liquid crystal display panel, and the backlight module comprises components such as an LED lamp, a PCB circuit board, a driving IC and the like. In addition, the display module logically comprises modules for obtaining modes, searching color temperature, adjusting color temperature and the like.
Before step S100, the tester can obtain a plurality of sets of actual values including color coordinates and brightness at the default color temperature level, and obtain the limit values of the color coordinates and the brightness according to the plurality of sets of actual values. For example, a manufacturer measures the color coordinates and brightness of the display module at a color temperature level of 6500K, thereby obtaining 30 sets of actual values including the color coordinates and brightness, and then calculates the values by a statistical evaluation method such as six Sigma (6Sigma), and further, the value range of the abscissa (X) of the color coordinates is 0.311 ± 0.015, the value range of the ordinate (Y) is 0.33 ± 0.013, and the value range of the brightness is 253 ± 27nits, which are obtained by the analysis and calculation of the six Sigma statistical method. It should be noted that the specific values of the color coordinates and the brightness are actually obtained as example values during the operation process, and are only used as examples to facilitate the description of the embodiment.
Therefore, the limit value of the color coordinate of the display module includes the upper limit value X of the abscissamaxLower limit value XminUpper limit value X of ordinatemaxLower limit value XminThe limit value of the brightness includes an upper limit value LmaxAnd a lower limit value Lmin。
Then, the display module can process the limit value of the color coordinate and the limit value of the brightness through the processing module 100 such as the central processing unit, specifically, the processing module 100 can combine two-by-two between the upper limit value and the lower limit value of the abscissa and the upper limit value and the lower limit value of the ordinate, thereby forming the value of the color coordinate applied to the display screen. For example, the value of the color coordinate may be (X)min＝0.296,Ymin＝0.317)、(Xmin＝0.296，Ymax＝0.343)、(Xmax＝0.326，Ymin＝0.317)、(Xmax＝0.326，Ymax0.343); since the user usually has a certain requirement on the minimum brightness of the display module under a specific condition, in the embodiment, the value of the brightness is preferably selected from the lower limit of the brightness, such as L mentioned in the above embodimentmin＝226nits。
S200, simulating according to the limit value of the color coordinate through the color matching module 200 so that the display module outputs a corresponding display image.
As mentioned in the above embodiments, the color coordinates may take on the value of (X)min＝0.296,Ymin＝0.317)、(Xmin＝0.296，Ymax＝0.343)、(Xmax＝0.326，Ymin＝0.317)、(Xmax＝0.326，Ymax0.343); it is understood that, on the chromaticity diagram, color coordinates correspond one-to-one to colors, and at the same time, color coordinates also correspond one-to-one to color temperature levels.
The tester can output corresponding display images according to the values of different color coordinates in sequence; for example, first based on a first set of color coordinates (X)min＝0.296,Ymin0.317), the display module may output the corresponding display image corresponding to the color coordinate by means of the color matching module 200 such as color matching software, and preferably, the display module may be in data connection with a computing device such as a PC to implement data communication, so that the PC device controls the display image output by the display module.
Specifically, the values of x and y are adjusted by simultaneously adjusting R, G, B input signals according to the relationship between x, y and R, G, B in the value of the color coordinate through an arithmetic device such as a PC; where R Gain is directly proportional to x in color coordinates, G Gain is directly proportional to y in color coordinates, and B Gain is inversely proportional to x and y.
Furthermore, the tester simulates corresponding R, G, B gains according to the values of different color coordinates in sequence, so that the display module outputs corresponding display images according to the gains of R, G, B.
S300, performing simulation according to the limit value of the brightness by the brightness adjusting module 300 to set the display brightness of the display image.
As mentioned in the above embodiments, the user usually has a certain requirement for the minimum brightness of the display module under a specific condition, and therefore, in the present embodiment, the lower limit value (L) of the limit values of the brightness is usedmin) As the value of brightness; the tester can control the image display brightness of the display module through the OSD menu in the display device, and the brightness adjustment mode is not limited to this. For example, the tester can not only adjust the brightness of the backlight module through the OSD menu, but also directly change the driving current of the backlight module through the current adjusting device so as to change the driving current of the backlight moduleThe driving current is adjusted according to the driving current, and the driving current is adjusted according to the driving current.
It can be understood that after steps S200 and S300 are executed, the tester simulates the display module to be in an extreme condition by combining software and hardware, that is, the color coordinate and the brightness of the display module are in the extreme condition, so that the display state of the display module meets the specific condition of the test.
Preferably, in steps S100 to S300, the tester can perform a secondary verification on the color coordinates of the image outputted by the display module or the display brightness of the image thereof through the optical measurement instrument 500 (e.g., a color analyzer, etc.) to ensure the accuracy of each step.
In S400, the color temperature adjusting module 400 adjusts the color temperature mode of the display module to configure the color temperature of the image.
Color temperature is a basic condition of image quality, and different color temperatures also bring different feelings to users. The display module provided by the invention has a plurality of color temperature modes, and the color temperature modes are configured with image color temperatures of different grades (such as 6500K, 7500K, 9300K and the like) for users to select.
In the actual operation process, the tester can select the color temperature mode by calling an on-screen display (OSD) of the display module, so that the display module can adjust the color temperature of the image corresponding to the color temperature mode. As mentioned in the above embodiments, the color temperature levels correspond to the color coordinates one-to-one, and the display module can further adjust R, G, B the gain according to the color coordinates. For example, the display module comprises a first color temperature mode, a second color temperature mode and a third color temperature mode, wherein the first color temperature mode, the second color temperature mode and the third color temperature mode correspond to color temperature grades, and the color temperature grades correspond to preset default color coordinates. For example, the first color temperature pattern corresponds to a color temperature of the image on the 6500K scale, and the color temperature of the image on the 6500K scale also corresponds to a color coordinate value, which may be: (X ═ 0.313 and Y ═ 0.329), but the present invention is not limited thereto. And the display module readjusts the RGB gain according to the preset color coordinate value, so that the color temperature grade corresponding to the color temperature mode is met.
It should be noted that, after the color temperature mode of the display module is adjusted, the display module changes the color coordinates and the color temperature by adjusting the RGB gains, and the adjustment of the RGB gains also affects the display brightness of the display module. That is, the display module is adjusted by steps S100, S200 and S300 to be in a specific condition meeting the test, and step S400 can simulate the specific operation of the user in actual use, such as: selecting a specific color temperature mode through an OSD menu of the display module; therefore, a tester can test the display module under a specific condition, and can simulate various color coordinates and brightness through the steps S100 to S300, that is, the display module under various specific conditions can be simulated, and the specific details can be determined according to the requirements of the tester, which is not described herein again.
Step S500, measuring the actual display brightness of the display image in the color temperature mode through the optical measurement instrument 500.
In step S500, the tester may measure the actual display brightness of the image displayed by the display module through an optical measurement instrument 500 (e.g., a color analyzer). For example, in step S300, the brightness value of the display module is adjusted to a lower limit (e.g., 226nits), and in step S400, after the tester adjusts the color temperature mode of the display module, the actual display brightness of the display image changes due to the sequential difference between the color coordinates, so it is necessary to re-detect whether the display brightness of the display module still meets the hard requirement of the user at the color temperature level (e.g., at least greater than or equal to 210 nits).
In practical operation, a tester can sequentially test the values of the four groups of color coordinates obtained according to the limit values of the color coordinates, and under the simulated specific condition, a user can have different requirements on the minimum brightness corresponding to different color temperature grades, and the tester can adjust and test the values one by one according to the test method of the display module.
Further, the aboveThe display module simulates the specific condition (for example, the value of the color coordinate is (X)min＝0.296,Ymin0.317), the brightness value is 226nits, the color temperature grade corresponding to the color temperature mode is 6500K), if the actual display brightness is detected, the display module meets the requirement in the test; according to the steps of the method, a tester can perform a plurality of times of cross tests on the display module under different values of color coordinates and different color temperature grades so as to detect whether the display module completely meets the requirements of users, if not, a manufacturer is required to be informed to adjust the image display brightness of the display module in a default or default state, and thus the limit value of the display brightness of the display module is changed.
In addition, as shown in fig. 2, the present invention further provides a testing system 10 for a display module, wherein the testing system 10 includes:
the processing module 100 is used for acquiring a limit value of color coordinates and a limit value of brightness in the display module;
the color matching module 200 is coupled to the processing module, and the color matching module 200 is used for performing simulation according to the limit value of the color coordinate so as to enable the display module to output a corresponding display image;

a color temperature adjusting module 400 for adjusting the color temperature mode of the display module to configure the color temperature of the image; and
the optical measurement instrument 500 measures the actual display brightness of the display image in the color temperature mode.
Preferably, the processing module 100 and the color matching module 200 are both configured on a PC device in data connection with the display module, and the PC device is in data connection with the display module, so that a tester can debug the display module through the PC device, for example, the processing module 100 and the color matching module 200 may be image software with computing capability, so as to obtain a value of a color coordinate according to an obtained limit value of the color coordinate, and output a display picture corresponding to the value of the color coordinate.
The brightness adjusting module 300 may be configured in the OSD menu of the display device, or may be a current adjusting device, which can be directly connected to the backlight module in the display module, so as to change the driving current of the backlight module to directly control the display brightness of the image output by the display module.
The color temperature adjusting module 400 is preferably an OSD menu of the display module, and the tester can directly select the color temperature mode through the OSD menu of the display module, so that the display module can adjust the color temperature of the image corresponding to the color temperature mode. The different color temperature modes correspond to different color temperature grades, the different color temperature grades are provided with corresponding default color coordinates, and the display module can further adjust R, G, B gains according to the default color coordinates so as to meet the color temperature grades corresponding to the color temperature modes.
In specific implementation, when the color matching module 200, the brightness adjustment module 300 and the color temperature adjustment module 400 adjust the display image of the display module, a tester can determine specific parameters of the display image through an optical measurement instrument 500 such as a color analyzer, so as to ensure the accuracy of each step; in addition, after the color temperature of the display module is adjusted by the color temperature adjusting module 400, the tester determines the display brightness of the current display frame by using the optical measuring instrument 500 to detect whether the brightness meets the hard requirement of the user.
It should be noted that the detailed embodiment of the testing method for a display module according to the present invention is described above, and is not repeated herein. In addition, each part or function in the control logic of the test method shown in fig. 1 can be implemented by a combination of software and hardware.
In summary, the present invention provides a testing method and a system thereof for a display module, which can simulate various extreme conditions of the display module according to a limit value of a color coordinate and a limit value of brightness in the display module by obtaining the limit value of the color coordinate and the limit value of the brightness, so as to adjust a color temperature level of the display module under the various extreme conditions, and finally achieve a purpose of testing an actual display brightness of the display module under the color temperature level. That is, the extreme conditions of the display module can be simulated through the limit values of the color coordinates and the multiple groups of values of the brightness, so that whether the actual display brightness of the display module still meets the requirements of users under the extreme conditions is detected. Therefore, the invention not only has strong practicability, but also can save certain test cost.
