Detailed Description
So that the manner in which the features and elements of the disclosed embodiments can be understood in detail, a more particular description of the disclosed embodiments, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings. In the following description of the technology, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, at least one embodiment may be practiced without these specific details. In other instances, well-known structures and devices may be shown in simplified form in order to simplify the drawing.
As shown in fig. 1, a method for detecting a light emitting unit according to an embodiment of the present disclosure includes:
s101, lighting the to-be-detected light emitting unit groups of the light emitting device in a time-sharing mode to obtain a lighting image of the to-be-detected light emitting unit groups, wherein the to-be-detected light emitting unit groups at least comprise two colors of to-be-detected light emitting units, and the to-be-detected light emitting units are spaced from each other.
And S102, obtaining a detection result corresponding to each light-emitting unit to be detected based on the lighting image.
In some embodiments, the light emitting unit to be detected may be a light emitting unit that needs to be detected in the light emitting device. Accordingly, a light emitting unit that does not need to be detected may be further included in the light emitting device. The light emitting units to be detected may be all or part of the light emitting units in the light emitting device.
In some embodiments, as shown in fig. 2A and 2B, the light emitting device 20 includes light emitting cells 201 to be detected of a plurality of colors. The color of the light emitting unit to be detected may include the light emitting color of the light emitting unit to be detected. There are many arrangements of the light emitting units 201 to be detected of the light emitting device 20, and two arrangements are exemplarily shown in the embodiment of the present disclosure, wherein:
as shown in fig. 2A, R represents a red light-emitting element to be detected, G represents a green light-emitting element to be detected, and B represents a blue light-emitting element to be detected. The light emitting units of the same color are arranged in series, such as: the light emitting cells of the same color are located in the same row, or the light emitting cells of the same color are located in the same column (not shown in fig. 2A).
As shown in fig. 2B, R represents a red light-emitting element to be detected, G represents a green light-emitting element to be detected, and B represents a blue light-emitting element to be detected. The light emitting units of different colors are arranged at intervals.
The arrangement of the light emitting units to be detected is only an exemplary illustration, and the arrangement of the light emitting units to be detected of the actual light emitting device is not limited.
In the embodiment of the present disclosure, the light emitting units to be detected in the light emitting unit groups to be detected may be allowed to have different colors, that is, the light emitting units to be detected of different colors may be simultaneously controlled to be lit when detecting the light emitting units. Compared with the mode that the light-emitting units with the same color can only be simultaneously lightened in the prior art, the method and the device can reduce the limitation condition for grouping the light-emitting units, so that the grouping mode and the lightening mode are more flexible.
In some embodiments, before the to-be-detected light emitting unit groups of the light emitting device are turned on in a time-sharing manner, the to-be-detected light emitting units may be grouped at specific intervals to obtain a plurality of to-be-detected light emitting unit groups. The specific interval may be the number of the to-be-detected light-emitting units spaced between two to-be-detected light-emitting units closest to each other in the same group.
Taking the light emitting device 20 shown in fig. 2A as an example, if the light emitting devices 20 are grouped by 1 light emitting cell at a specific interval, the light emitting devices 20 can be divided into 4 groups, and the grouping results are shown in fig. 3A to 3D, wherein the gray filled area is the same group of light emitting cells to be detected.
Taking the light emitting device 20 shown in fig. 2B as an example, if the light emitting devices 20 are grouped into 3 light emitting cells at a specific interval, the light emitting devices 20 can be divided into 8 groups, and the grouping result is shown in fig. 4A to 4H, in which the gray filled area is the same group of light emitting cells to be detected.
Optionally, the specific interval may be dynamically adjusted according to different detection requirements. The specific intervals of the different groups of light-emitting units to be detected may be the same or different. For example, all the light emitting units to be detected may be grouped at a certain interval a; or a part of the light-emitting units to be detected may be grouped according to a specific interval a, and another part of the light-emitting units to be detected may be grouped according to a specific interval b, and the specific grouping manner is not limited.
In some embodiments, the specific interval may be set based on a resolution of a photographing device that acquires the lighted image.
Alternatively, when the resolution of the light emitting device (i.e., the number of light emitting cells to be detected in the light emitting device) is lower than the resolution of the photographing device (i.e., the number of pixels of the photographing device), the resolution of the group of light emitting cells to be detected (i.e., the number of light emitting cells to be detected in the group of light emitting cells to be detected) is also lower than the resolution of the photographing device, and thus the specific interval may be an arbitrary value.
Alternatively, when the resolution of the light emitting device is higher than that of the photographing device, the resolution of the group of light emitting cells to be detected is not necessarily lower than that of the photographing device. When the resolution of the light emitting unit group to be detected is greater than or equal to that of the shooting device, the accuracy of the detection result is low. Therefore, the resolution of the light emitting unit group to be detected can be reduced by increasing the specific interval, and the accuracy of the detection result can be improved under the condition that the resolution of the shooting device is not changed.
In some embodiments, the number of light emitting units to be detected in each group of light emitting units to be detected is the same, or the number of light emitting units to be detected in at least two groups of light emitting units to be detected is different. Wherein:
as shown in fig. 3A, 3B, 3C, and 3D, the number of the light-emitting units to be detected in each light-emitting unit group to be detected is the same, and each light-emitting unit group to be detected includes 9 light-emitting units to be detected, where the gray filling area is the same group of light-emitting units to be detected.
As shown in fig. 4A to 4H, each group of light-emitting units to be detected in fig. 4A, 4B, 4E and 4F includes 4 light-emitting units to be detected, and each group of light-emitting units to be detected in fig. 4C, 4D, 4G and 4H includes 2 light-emitting units to be detected, where the gray filling region is the same group of light-emitting units to be detected.
In some embodiments, the duration in which all the groups of light-emitting units to be detected are lit once includes a plurality of time slices. In the process of lighting the light emitting unit groups to be detected in a time-sharing manner, the same light emitting unit group to be detected can be repeatedly lighted in each time slice of the plurality of time slices, and different light emitting unit groups to be detected can be lighted in different time slices.
The grouping shown in fig. 3A to 3D is taken as an example. Assuming that the same light emitting unit group to be detected is repeatedly lit for 3 times in each time slice, where each light emitting unit group to be detected corresponds to one time slice, the lighting process may be as shown in fig. 5A to 5D. Wherein:
as shown in fig. 5A, the group of light-emitting units to be detected shown in fig. 3A is repeatedly turned on 3 times in the first time slice, wherein the gray filling area is the same group of light-emitting units to be detected.
As shown in fig. 5B, the group of light-emitting units to be detected shown in fig. 3B is repeatedly lit 3 times in the second time slice, wherein the gray filling area is the same group of light-emitting units to be detected.
As shown in fig. 5C, the group of light-emitting units to be detected shown in fig. 3C is repeatedly lit 3 times in the third time slice, wherein the gray filling area is the same group of light-emitting units to be detected.
As shown in fig. 5D, the group of light-emitting units to be detected shown in fig. 3D is repeatedly lit 3 times in the fourth time slice, wherein the gray filling area is the same group of light-emitting units to be detected.
It is thus possible to achieve the effect that each group of light-emitting units to be detected is repeatedly lit up 3 times.
In some embodiments, a time period during which all the light-emitting unit groups to be detected are turned on once is used as one time-sharing period. In the process of lighting the group of light-emitting units to be detected in time division, the operation of lighting the group of light-emitting units to be detected may be repeatedly performed in a plurality of time division periods.
Alternatively, the grouping manner shown in fig. 3A to 3D is taken as an example. Assuming that each time-sharing period includes a plurality of time slices, lighting one to-be-detected light-emitting unit group once in each time slice, where lighting each to-be-detected light-emitting unit group once is a time-sharing period, the lighting process may be as shown in fig. 6A to 6C. Wherein:
as shown in fig. 6A, in the first time slice, the light-emitting unit group to be detected shown in fig. 3A is lit once, in the second time slice, the light-emitting unit group to be detected shown in fig. 3B is lit once, in the third time slice, the light-emitting unit group to be detected shown in fig. 3C is lit once, and in the fourth time slice, the light-emitting unit group to be detected shown in fig. 3D is lit once, so that the first time slice is completed; as shown in fig. 6B and 6C, the lighting process shown in fig. 6A is repeated for the second time-division period and the third time-division period, wherein the gray filled area is the same group of light-emitting units to be detected.
It is thus possible to achieve the effect that each group of light-emitting units to be detected is repeatedly lit up 3 times.
In some embodiments, in the process of lighting the light emitting unit groups to be detected of the light emitting device in a time-sharing manner, each light emitting unit group to be detected may be sequentially lighted, or each light emitting unit group to be detected may be randomly lighted.
In some embodiments, the operation of lighting the next light-emitting unit group to be detected may be triggered when the lighting image of the currently-lit light-emitting unit group to be detected is received, and if the lighting image of the currently-lit light-emitting unit group to be detected is not received, the operation of lighting the current light-emitting unit group to be detected may be repeatedly triggered to acquire the lighting image, thereby ensuring that the lighting image may be successfully acquired and avoiding missing inspection.
In some embodiments, obtaining a detection result corresponding to each light-emitting unit to be detected based on the lighting image may include:
determining an optical parameter value of the light-emitting unit to be detected based on the lighting image; and when the optical parameter value of the light-emitting unit to be detected is out of the preset parameter range, determining the light-emitting unit to be detected as an abnormal light-emitting unit.
Alternatively, the preset parameter range may be an optical parameter threshold range preset for the optical parameter, and the detection result represented by the optical parameter value within the preset parameter range may be considered as normal, and the detection result represented by the optical parameter value outside the preset parameter range may be considered as abnormal. The preset parameter range can be set according to the actual application scene. The preset parameter range can be changed at any time.
For example, if the preset parameter range is [ a, b ], if the optical parameter value of the detection result is greater than or equal to a and less than or equal to b, the light-emitting unit to be detected corresponding to the optical parameter value is considered to be a normal light-emitting unit; and if the optical parameter value of the detection result is smaller than a or larger than b, the light-emitting unit to be detected corresponding to the optical parameter value is considered as an abnormal light-emitting unit.
In some embodiments, the optical parameter value may include at least one of luminance and chrominance.
In some embodiments, when the brightness of the light emitting unit to be detected is lower than a threshold value, the light emitting unit to be detected can be marked as a dead spot.
The disclosed embodiments provide a light-emitting unit detection apparatus, including a processor and a memory storing program instructions, the processor being configured to execute the above-mentioned light-emitting unit detection method when executing the program instructions.

Further, the memory 302 may include high speed random access memory and may also include non-volatile memory.

In some embodiments, referring to fig. 8, the light emitting unit detecting device 40 may include:
the control chip 401 is configured to illuminate the to-be-detected light emitting unit groups of the light emitting device in a time-sharing manner to obtain illuminated images of the to-be-detected light emitting unit groups, and obtain detection results corresponding to each to-be-detected light emitting unit based on the illuminated images, wherein the to-be-detected light emitting unit groups at least include two colors of to-be-detected light emitting units, and the to-be-detected light emitting units are spaced from each other;
a photographing device 402 configured to capture a lighting image when the light emitting unit group to be detected is lit.
In some embodiments, the control chip 401 may include, but is not limited to: one or more of a central processing unit, a microprocessor or a singlechip. The capture device 402 may include, but is not limited to: camera type microscopic imaging system. Optionally, the control chip 401 is connected to the light emitting device, and is configured to control the light emitting elements to be detected in the light emitting device to be turned on in a time-sharing manner. Alternatively, the control chip 401 and the photographing device 402 have a connection relationship including at least one of a wired connection and a wireless connection. The control chip 401 can control the photographing device 402 to photograph a lighting image when the light emitting cell group to be detected is lighted.
In some embodiments, the shooting device 402 may send the shot lighting image of the currently-lighted light-emitting unit group to be detected to the control chip 401 in real time, the control chip 401 may trigger the operation of lighting the next light-emitting unit group to be detected when receiving the lighting image, and if the lighting image is not received, the operation of triggering the light-emitting device to light the current light-emitting unit group to be detected may be repeated to obtain the lighting image, thereby ensuring that the lighting image may be successfully acquired and avoiding missing inspection.
In some embodiments, before the controlling chip 401 time-divisionally lights the group of light emitting cells to be detected of the light emitting device, the controlling chip is further configured to:
and grouping the light-emitting units to be detected at specific intervals to obtain a plurality of light-emitting unit groups to be detected.
Taking the light emitting device 20 shown in fig. 2A as an example, if the light emitting devices are grouped into 1 light emitting unit at a specific interval, the control chip 401 may divide the light emitting device 20 into 4 light emitting unit groups to be detected, and the grouping result is shown in fig. 3A to 3D, where the gray filling area is the same group of light emitting units to be detected.
Taking the light emitting device 20 shown in fig. 2B as an example, if the light emitting devices are grouped into 3 light emitting cells at a specific interval, the control chip 401 may divide the light emitting device 20 into 8 light emitting cell groups to be detected, and the grouping result is shown in fig. 4A to 4H, where the gray filling area is the same group of light emitting cells to be detected.
In some embodiments, the particular interval is set based on the resolution of the capture device 402 that acquired the illuminated image.
In some embodiments, the time duration that all the light-emitting unit groups to be detected are lighted once is used as a time-sharing period;
when the control chip 401 turns on the light emitting unit group to be detected of the light emitting device in a time-sharing manner, the control chip is configured to:
the operation of lighting the group of light emitting cells to be detected is repeatedly performed in a plurality of time-sharing periods.
The grouping shown in fig. 3A to 3D is taken as an example. Assuming that the control chip 401 repeatedly lights the same light-emitting unit group to be detected 3 times in each time slice, where each light-emitting unit group to be detected corresponds to one time slice, the lighting process may be as shown in fig. 5A to 5D. Wherein:
as shown in fig. 5A, the control chip 401 repeatedly lights up the group of light emitting units to be detected shown in fig. 3A 3 times in the first time slice, where the gray filling area is the same group of light emitting units to be detected.
As shown in fig. 5B, the control chip 401 repeatedly lights up the group of light emitting units to be detected shown in fig. 3B 3 times in the second time slice, where the gray filling area is the same group of light emitting units to be detected.
As shown in fig. 5C, the control chip 401 repeatedly lights up the group of light emitting units to be detected shown in fig. 3C 3 times in the third time slice, where the gray filling area is the same group of light emitting units to be detected.
As shown in fig. 5D, the control chip 401 repeatedly lights up the group of light emitting units to be detected shown in fig. 3D 3 times in the fourth time period, where the gray filling area is the same group of light emitting units to be detected.
The control chip 401 can thus achieve the effect that each light-emitting unit group to be detected is repeatedly lit up 3 times.
In some embodiments, the duration for lighting all the light-emitting unit groups to be detected once comprises a plurality of time slices;
when the control chip 401 turns on the light emitting unit group to be detected of the light emitting device in a time-sharing manner, the control chip is configured to:
and repeatedly lightening the same light-emitting unit group to be detected in each time slice of the plurality of time slices, and lightening different light-emitting unit groups to be detected in different time slices.
In some embodiments, a time period during which all the light-emitting unit groups to be detected are turned on once is used as one time-sharing period. In the process of lighting the group of light-emitting units to be detected in time division, the operation of lighting the group of light-emitting units to be detected may be repeatedly performed in a plurality of time division periods.
Alternatively, the grouping manner shown in fig. 3A to 3D is taken as an example. Assuming that each time-sharing period includes a plurality of time slices, the control chip 401 lights the same light-emitting unit group to be detected once in each time slice, where each light-emitting unit group to be detected is lighted once in one time-sharing period, and then the process of controlling lighting by the control chip 401 may be as shown in fig. 6A to 6C. Wherein:
as shown in fig. 6A, the control chip 401 controls to light the to-be-detected light-emitting unit group shown in fig. 3A once in a first time slice, controls to light the to-be-detected light-emitting unit group shown in fig. 3B once in a second time slice, controls to light the to-be-detected light-emitting unit group shown in fig. 3C once in a third time slice, and controls to light the to-be-detected light-emitting unit group shown in fig. 3D once in a fourth time slice in a first time-sharing period, so as to complete the first time-sharing period; as shown in fig. 6B and 6C, the control chip 401 repeats the control lighting process shown in fig. 6A in the second time-division period and the third time-division period, wherein the gray filling area is the same group of light-emitting units to be detected.
The control chip 401 can thus achieve the effect that each light-emitting unit group to be detected is repeatedly lit up 3 times.
In some embodiments, the control chip 401, when time-divisionally lighting the group of light-emitting units to be detected of the light-emitting device, is configured to:
and sequentially lighting each light-emitting unit group to be detected or randomly lighting each light-emitting unit group to be detected.
In some embodiments, when obtaining the detection result corresponding to each light-emitting unit to be detected based on the lighting image, the control chip 401 is configured to:
determining an optical parameter value of a light-emitting unit to be detected based on the lighting image;
and when the optical parameter value of the light-emitting unit to be detected is out of the preset parameter range, determining that the light-emitting unit to be detected is an abnormal light-emitting unit.
In some embodiments, the optical parameter value comprises at least one of luminance and chrominance.
