It should be understood that the specific embodiments described herein are intended to be illustrative only and are not intended to be limiting. It will be apparent to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating examples thereof.

Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
Before explaining the technical solutions provided by the embodiments of the present application, in order to facilitate understanding of the embodiments of the present application, the present application first specifically explains the problems existing in the prior art:
for the OLED display module, especially for an Active-matrix Organic Light-Emitting Diode (AMOLED) display module, as the service life of the OLED display module increases, the aging of the OLED display module and the brightness of the OLED display module gradually decrease. For example, if the light-emitting brightness of the OLED display module at the time of factory shipment is assumed to be expressed as a percentage of 100%, the light-emitting brightness of the OLED display module may gradually decrease to 99%, 98%, … …, 95% or even lower as the OLED display module is used for a longer period of time.
The inventor of the present application finds that, due to the existence of process differences during production, the degradation degrees of the light-emitting brightness of different OLED display modules are different, that is, the corresponding relationship between the service time and the light-emitting brightness of different OLED display modules is different. In the embodiment of the present application, the correspondence between the service life of the OLED display module and the light-emitting brightness can be represented by a life curve of the light-emitting brightness of the OLED display module.
Fig. 1 schematically shows the correspondence between the service life and the light emission brightness of the OLED display module. In fig. 1, the abscissa represents the duration of use of the display module, the ordinate represents the remaining proportion of the emission luminance of the display module, the correspondence between the duration of use of the display module a and the emission luminance is represented by a solid line, and the correspondence between the duration of use of the display module B and the emission luminance is represented by a dashed line. In the embodiment of the present application, the remaining proportion of the light-emitting brightness of the display module can be understood as a ratio of the light-emitting brightness of the display module at each use time to the rated light-emitting brightness of the display module at the factory. As shown in fig. 1, although the light-emitting luminances of the display module a and the display module B both decrease with the increase of the operating time, the operating time and the light-emitting luminance of the display module a and the display module B have different correspondences. If the brightness of the display module B is calculated according to the correspondence between the operating time of the display module a and the brightness of the light, the deviation between the calculated brightness of the display module B and the actual brightness of the display module B is large.
In the existing scheme, the luminance of different OLED display modules is usually calculated according to the corresponding relationship between the same use duration and the luminance of the OLED display module, so that the technical problem that the error of the determined luminance of the OLED display module is large exists.
In order to solve the problems in the prior art, embodiments of the present application provide a method, an apparatus, a device, and a computer storage medium for determining a luminance of a display module.
The technical idea of the embodiment of the application is as follows: the method comprises the steps of setting an identifier for each display module in advance, obtaining a first corresponding relation corresponding to the identifier through the identifier, and determining that the light emitting brightness error of the display module is small or even no error occurs through the first corresponding relation because the first corresponding relation is the corresponding relation of the light emitting brightness of the display module and the service life, so that the accuracy of the determined light emitting brightness of the display module is improved.
The following first describes a method for determining the brightness of the display module according to the embodiment of the present application.
Fig. 2 is a flowchart illustrating a method for determining a luminance of a display module according to an embodiment of the present disclosure. As shown in fig. 2, the method may include the steps of:
s101, acquiring an identifier of a display module, a first service life of the display module and a first corresponding relation corresponding to the identifier;
s102, determining the first luminous intensity of the display module corresponding to the first service life according to the first corresponding relation.
Specific implementations of the above steps will be described in detail below.
The method for determining the brightness of the display module in the embodiment of the application obtains the identifier of the display module, the first using time of the display module and the first corresponding relation corresponding to the identifier, wherein the first corresponding relation is the corresponding relation between the brightness of the display module and the using time of the display module; and determining the first luminous brightness of the display module corresponding to the first service life according to the first corresponding relation. The display module of the embodiment of the application is provided with the identification, the first corresponding relation corresponding to the identification can be obtained through the identification, and the first corresponding relation is the corresponding relation between the luminous brightness of the display module and the service time, so that the luminous brightness error of the display module determined through the first corresponding relation is small, even no error occurs, and the accuracy of the determined luminous brightness of the display module is improved.
Specific implementations of the above steps are described below.
Firstly, the method includes the steps of S101, obtaining the identification of the display module, the first service time of the display module and the first corresponding relation corresponding to the identification.
In the embodiment of the present application, the first corresponding relationship is a corresponding relationship between the brightness of the display module and the duration of the display module. The relationship between the luminance of the display module and the service life of the display module is, for example, a life curve of the luminance of the OLED display module shown in fig. 1.
In some embodiments, the usage duration of the display module (including the first usage duration and the second usage duration later) may be determined based on a difference between the production time of the display module and the current time. As an example, the first duration of use of the display module may be determined based on a duration of use of a terminal device installed in the display module, for example, the first duration of use of the display module may be obtained by reading a powered-on time in a built-in file of the terminal device.
In the embodiment of the application, the display module is provided with the identifier in advance, and the identifier corresponds to the first corresponding relation one to one. The identifier may be an Identity Document (ID) or other information representing the Identity of the display module.
The display module comprises a display panel and a Driver IC (Driver IC) for providing driving voltage for the display panel. In order to facilitate easy acquisition of the identifier of the display module and reduce the cost for setting the identifier, in some embodiments, the identifier of the display module may be burned into the driving chip. Therefore, when the mark is used subsequently, the mark is read from the driving chip, so that the mark can be conveniently obtained.
In further research by the inventors of the present application, it is found that the process difference of the OLED display modules in different production batches is generally large, and therefore, the life curves of the emission luminances of the OLED display modules in different production batches have large difference. However, the process difference of the OLED display modules in the same production batch is usually small or even no difference, so the life curves of the light emitting brightness of the OLED display modules in the same production batch have small or even the same difference.
Based on the finding, the inventor of the present application considers that since the life curves (first corresponding relations) of the light emitting luminance of the OLED display modules in the same production batch are smaller or even the same, the OLED display modules in the same production batch can use the same first corresponding relations, and accordingly, the OLED display modules in the same production batch can also use the same marks, so as to reduce the number of the first corresponding relations to be determined, and reduce the calculation cost and the storage cost of the first corresponding relations. For example, a plurality of display modules (e.g., 100 display modules) in the same production lot may be provided with the same identifier and the same first corresponding relationship.
In some embodiments, the first correspondence may be determined by:
as shown in fig. 3, before S101, the method for determining the light emitting brightness of the display module provided in the embodiment of the present application may further include the following steps:
s1001, one or more modules are selected from the display modules or the first display modules in the same production batch with the display modules as target display modules.
Specifically, for each display module, after the display modules in the production batch in which the display module is located are produced, the display module can be used as a target display module, and other display modules in the production batch in which the display module is located can be used as target display modules to test the target display modules.
S1002, a plurality of second light-emitting luminances corresponding to the target display module during a plurality of second service durations are obtained.
In the testing process, a plurality of second light-emitting luminances corresponding to the target display module during a plurality of second use durations may be obtained, for example, the light-emitting luminance of the target display module during the use duration t1 'is x 1', the light-emitting luminance of the target display module during the use duration t2 'is x 2', … …, and the light-emitting luminance of the target display module during the use duration tn 'is xn', and n is a positive integer.
S1003, determining a first corresponding relation according to the plurality of second using durations and the plurality of second light-emitting luminances corresponding to the second using durations.
Specifically, since the testing process of the display module is shorter than the actual using process of the display module, the plurality of second using durations with shorter time span and the plurality of second light-emitting luminances corresponding to the second using durations can be processed based on the data fitting method, so as to obtain the first corresponding relationship with longer time span.
Of course, in order to ensure the accuracy of the obtained first corresponding relationship, the second light-emitting brightness corresponding to the second duration of use of the target display module may also be continuously obtained, and the first corresponding relationship may be updated in real time or at regular time based on the second light-emitting brightness corresponding to the second duration of use of the target display module. For example, within a preset time period (for example, 1 year or more) after the target display module is produced, the second light emitting brightness corresponding to the second use duration of the target display module is obtained at regular time or in real time, and then the first corresponding relationship is updated at regular time or in real time according to the second light emitting brightness corresponding to the second use duration of the target display module obtained at regular time or in real time.
By updating the first corresponding relation at regular time or in real time, the accuracy of the acquired first corresponding relation can be ensured, and the accuracy of the finally determined brightness of the OLED display module is further ensured. That is, one or a few display modules can be extracted from a plurality of display modules (for example, 100 display modules) in the same production batch as the target display module, and the second light-emitting brightness corresponding to the second service duration of the target display module is obtained in real time or in real time through real-time or timed monitoring of the target display module, so as to obtain the first corresponding relationship of the plurality of display modules in the production batch.
The above is a specific implementation of S101, and a specific implementation of S102 is described below.
S102, determining the first luminous intensity of the display module corresponding to the first service life according to the first corresponding relation.
Specifically, the first corresponding relationship may be a life curve of the light emitting brightness of the OLED display module shown in fig. 1. In S102, a remaining proportion of the light-emitting brightness of the display module corresponding to the first usage duration may be determined according to the first usage duration; and then, determining the first luminous brightness of the display module corresponding to the first service time according to the predetermined rated luminous brightness of the display module and the residual proportion of the luminous brightness of the display module.
Of course, the ordinate of fig. 1 can also be the residual luminance (unit nit, also called candela/square meter (cd/m)) of the display module2)). That is to say, the first luminance brightness of the display module corresponding to the first service life can be determined directly according to the first corresponding relationship and the first service life.
In order to improve the display effect of the OLED display module, in some embodiments, after the first luminance of the display module is determined, luminance compensation may be performed on the OLED display module.
Specifically, as shown in fig. 4, the method for determining the light emitting brightness of the display module provided in the embodiment of the present application may further include the following steps S103, S104, and S105.
S103, obtaining a target value of the luminous brightness of the display module. The target value of the emission luminance may be, for example, a rated emission luminance at the time of shipment of the display module.
And S104, determining the brightness compensation quantity of the display module according to the first light-emitting brightness and the target value. Specifically, a difference value between the first luminance brightness of the display module and the rated luminance brightness is calculated to obtain a luminance compensation amount of the display module, wherein the luminance compensation amount is the difference value between the first luminance brightness of the display module and the rated luminance brightness.
And S105, performing brightness compensation on the display module according to the brightness compensation quantity.
Specifically, the voltage compensation amount of the driving voltage of the display module is determined according to the calculated brightness compensation amount. The driving voltage is a voltage for driving the light emitting elements in the display module to emit light, which is also called a gray scale voltage, and is generally denoted by Vdata. The magnitude of the driving voltage influences the luminance of the light-emitting element, so that the luminance of the display module can be compensated by adjusting the magnitude of the driving voltage. In some embodiments, for example, the correspondence between the luminance compensation amount and the voltage compensation amount may be established in advance. When the voltage compensation amount is determined, the voltage compensation amount corresponding to the luminance compensation amount may be determined according to a correspondence between the luminance compensation amount and the voltage compensation amount. Of course, the voltage compensation amount may be determined in other manners, for example, the voltage compensation amount may be determined by real-time calculation.
After the voltage compensation amount of the driving voltage of the display module is determined, the voltage value of the driving voltage can be adjusted to the target voltage value according to the voltage compensation amount. Namely, the driving voltage increases or decreases the voltage compensation amount on the basis of the original voltage value, so that the voltage compensation of the driving voltage is realized, and further, the light-emitting brightness compensation of the display module is realized.
Fig. 5 schematically shows a specific application example of the present application. As shown in fig. 5, at the factory, the identifier is burned into the driving chip of each display module, and the first corresponding relationship of each display module is determined. For example, the display modules in the same production batch burn the same identifier, and the display modules in the same production batch have the same first corresponding relationship. The first device 501 at the factory sends the burned identifiers and the first corresponding relationship corresponding to each identifier to the server 502, and the server 502 stores the identifiers and the first corresponding relationship corresponding to each identifier. In the using process of the display module, the terminal device 503 for installing the display module sends request information to the server 502, wherein the request information contains the identifier of the display module. The server 502 queries the corresponding first corresponding relationship according to the identifier of the display module in the received request information, and feeds the first corresponding relationship back to the terminal device 503. The terminal device 503 calculates the first luminance of the display module corresponding to the first duration according to the first corresponding relationship.
