The main reason is that the OLED process is complex, and the evaporation process is difficult to achieve very good flatness, so that the difference of the luminance of each sub-pixel under the same external condition is large, and each sub-pixel has to be compensated to achieve the panel display standard.
Among them, a display based On a COG (Chip On Glass) technology may have dark spots, which is called COG Mura, and generally, because expansion coefficients of an IC board (a device board including metal and semiconductor elements) and a Glass substrate are different, when the IC board is bonded at a high temperature, the IC board is easily warped, so that COG Mura may occur at two ends of the IC board, the COG Mura is generally located at the bottom of the display, light emitted from an LED (light emitting diode) in a backlight cannot pass through the COG Mura, and thus luminance display uniformity of the display is poor, and a display effect of the display is poor.

Based on the above hardware structure, an embodiment of the display adjustment method of the present application is provided.
Referring to fig. 2, fig. 2 is a schematic flowchart of a first embodiment of a display adjustment method according to the present application, the method is applied to a display adjustment device, and the method includes the following steps:
step S11: a dark spot area of the display to be adjusted is obtained.
It should be noted that the main implementation body of the present application is a display adjustment device, and the device structure refers to the above description, which is not described herein again. The display to be adjusted generally refers to a display manufactured for the first time in a display production workshop, and various parameters and structures of the display to be adjusted are adjusted, for example, the distance between adjacent light emitting diodes (i.e., LEDs) of the display to be adjusted is uniform, the working voltage of the light emitting diodes of the display to be adjusted is also uniform and constant, and the like; in the present application, the display to be adjusted refers to a main structure of the display to be adjusted, and may refer to a display that does not include structures such as a display housing and a display bracket; in addition, the dark color spot area may be determined by the terminal device based on the brightness display information of the display to be adjusted, or may be determined by a technician based on the brightness display information of the display to be adjusted, and after the technician determines the dark color spot area of the display to be adjusted, the dark color spot area is input to the display adjusting device, or the dark color spot area of the display to be adjusted is determined by other dark color spot detection methods. Wherein the dark spots are COG Mura.
Further, step S11 includes: acquiring first brightness display information of the display to be adjusted; determining the dark spot area based on the first luminance display information.
It should be noted that, the display to be adjusted may be used to play a pure color picture, and based on the luminance display effect of the pure color picture, that is, the first luminance display information, the dark spot area with uneven luminance display may be determined. It is understood that the luminance display information may include a display luminance display uniformity condition, a luminance display non-uniform area, a luminance display more uniform area, and the like.
Step S12: and determining the light emitting diode corresponding to the dark spot area in the display to be adjusted as a first light emitting diode to be adjusted.
It should be noted that, if there is a normal display region in the display to be adjusted, that is, there is no region with a dark spot, it is not necessary to adjust the position of the light emitting diode corresponding to the region without the dark spot, but only needs to adjust the position of the light emitting diode corresponding to the dark spot region, at this time, it is necessary to determine the first light emitting diode to be adjusted corresponding to the dark spot region, so as to avoid the problem that the luminance of the display region without the problem is displayed unevenly due to the adjustment of the light emitting diode in the non-dark spot region.
Step S13: and acquiring the light emitting angle of the first light emitting diode to be adjusted.
It should be noted that the display to be adjusted in the present application refers to a display using light emitting diodes as a backlight module, the light emitting diodes of different colors all have the same light emitting angle, usually the light emitting angle is 120 degrees, and the embodiments of the present application are explained by taking the light emitting angle of 120 degrees as an example. It is understood that the first led to be adjusted and the leds in the display to be adjusted both have a light emitting angle of 120 degrees.
Further, the display to be adjusted generally has a backlight film, and the backlight film is disposed on the light emitting side of the light emitting diode in the display to be adjusted; the step S12 further includes: and acquiring the light emitting angle of the first light emitting diode to be adjusted through the backlight film.
Specifically, the light emitting angle of the light emitted by the light emitting diode after passing through the backlight film does not change, and in some cases, the light emitting angle of the light emitted by the light emitting diode after passing through the backlight film changes, and at this time, the light emitting angle of the light emitted by the light emitting diode after passing through the backlight film is required to be used as a reference, rather than the light emitting angle of the light emitting diode itself.
Step S14: and obtaining the position information of the first light-emitting diode to be adjusted based on the light-emitting angle and the dark spot area.
Specifically, before step S13, the method further includes: acquiring the area of the dark spot area; obtaining a setting distance of the first light-emitting diode to be adjusted based on the area of the region and the light-emitting angle; accordingly, step S14 includes: and obtaining the position information of the first light-emitting diode to be adjusted based on the set interval and the dark spot area.
It should be noted that the light emitting diode has a light emitting angle, a low brightness region where light cannot be irradiated exists between the adjacent first light emitting diodes to be adjusted, and the dark spot region is a region where light cannot be irradiated by the light emitting diode.
In specific application, the positions of the dark spot regions are different, the position of the first light-emitting diode to be adjusted needs to be adjusted, so that the low-brightness region of the first light-emitting diode to be adjusted corresponds to the dark spot region (the position relationship corresponds to the dark spot region), and the setting distance of the first light-emitting diode to be adjusted is determined according to the region area of the dark spot region, so that the dark spot regions in the low-brightness region can be overlapped.
Referring to FIG. 3, FIG. 3 is a schematic diagram of the relationship between the position of the light emitting diodes and the dark spot areas of the display of the present application; the adjusted display is A, the first light-emitting diode to be adjusted is 02, the dark spot area is 01, the light ray 04 corresponding to the maximum light ray emission angle of the first light-emitting diode to be adjusted is a triangular area 03; two adjacent first light-emitting diodes 02 to be adjusted in the adjusted display A emit light rays, and dotted lines 04 are light rays corresponding to the maximum light-emitting angle of the first light-emitting diodes 02 to be adjusted respectively; the triangular area 03 is a low-brightness area where the light emitted by the first light-emitting diode to be adjusted cannot be irradiated. Because the triangular area 03 does not have the light emitted by the first light-emitting diode 02 to be adjusted, the brightness is low; the dark spot area 01 is a block area corresponding to the arc line in fig. 3, and when the dark spot area 01 is overlapped with the low brightness area (the triangular area 03), the light 04 (the dotted line is the light corresponding to the maximum light emission angle) corresponding to the maximum light emission angle of the adjacent first light-emitting diode 02 to be adjusted can still emit the adjusted display a without being blocked by the dark spot area 01, so that the brightness of the dark spot area 01 of the display is not affected by the dark spot area 01, and the brightness of the entire adjusted display a is displayed uniformly.
In a specific application, after the setting distance of the first light emitting diode to be adjusted is preliminarily determined according to the area of the dark spot (the setting distance corresponding to different areas of the dark spot area may be determined according to an experimental result or experience, referring to fig. 3, when the dark spot area is larger, the setting distance between the first light emitting diodes to be adjusted is increased to increase the size of the triangular area, so that the triangular area coincides with the dark spot area, and thus the light emitted by the first light emitting diode to be adjusted is not blocked by the dark spot area), based on the setting distance, adjusting the position of a first light emitting diode to be adjusted in the display to be adjusted, adjusting the distance between the first light emitting diode to be adjusted to the setting distance, then, translation adjustment is carried out so that a low-brightness area (triangular area) is overlapped with a dark spot area; referring to fig. 3, the adjustment of the position of the first to-be-adjusted led 02 is performed by translating the first to-be-adjusted led 02, where the triangular area coincides with the dark spot area (i.e. the triangular area includes the dark spot area exactly), and the translation direction is the same as the right side or the same as the left side.
It can be understood that the position information includes the setting distance and the position of the first light emitting diode to be adjusted after translation; and adjusting the position of the first light-emitting diode to be adjusted, namely adjusting the setting distance of the first light-emitting diode to be adjusted and adjusting the position of the first light-emitting diode to be adjusted in a translation manner.
Step S15: and adjusting the position of the first light-emitting diode to be adjusted based on the position information to obtain an adjusted display.
In a specific application, the distance between the first to-be-adjusted light emitting diodes in the to-be-adjusted display has an initial distance and a preset position, and after a dark spot area of the to-be-adjusted display is determined, the position of the first to-be-adjusted light emitting diode corresponding to the dark spot area needs to be adjusted.
Determining light-emitting diodes needing to be adjusted, namely first light-emitting diodes to be adjusted and position information (including a setting distance and a position after translation) of the first light-emitting diodes to be adjusted through position information of the dark spot areas, and determining the setting distance between the adjacent first light-emitting diodes to be adjusted through area areas of the dark spot areas, wherein the position information includes the position information of the first light-emitting diodes to be adjusted and the setting distance between the adjacent first light-emitting diodes to be adjusted; and adjusting the first to-be-adjusted light-emitting diode based on the position information to obtain an adjusted display, wherein the adjusted display is the adjusted to-be-adjusted display with uniform brightness display.
Further, after step S15, the method further includes: acquiring second brightness display information of the adjusted display; determining an adjustment area in the adjusted display based on the second brightness display information; determining the light emitting diode corresponding to the adjusting area in the adjusted display as a second light emitting diode to be adjusted; determining a correction interval of the second light-emitting diode to be adjusted based on the brightness display information corresponding to the adjustment area in the second brightness display information; and adjusting the position of the second light emitting diode to be adjusted by utilizing the correction interval to obtain the corrected display.

Determining a region to be adjusted with uneven brightness display based on second brightness display information of the adjusted display, wherein the light emitting diode corresponding to the region to be adjusted is a second light emitting diode to be adjusted, and the distance between the second light emitting diodes to be adjusted needs to be adjusted; the distance between the light emitting diodes to be adjusted is determined to be increased or decreased based on the display effect, generally, the area to be adjusted is brighter, the distance between the adjacent second light emitting diodes to be adjusted needs to be decreased, the area to be adjusted is darker, and the distance between the adjacent second light emitting diodes to be adjusted needs to be increased.
Referring to fig. 3, when the first to-be-adjusted light emitting diode 02 is used as a second to-be-adjusted light emitting diode and the distance between the second to-be-adjusted light emitting diodes is adjusted, the adjacent second to-be-adjusted light emitting diodes in the second to-be-adjusted light emitting diodes may be simultaneously translated along opposite directions (one is translated leftward and one is translated rightward), for example, the adjacent left second to-be-adjusted light emitting diodes in the second to-be-adjusted light emitting diodes are translated leftward, the adjacent right second to-be-adjusted light emitting diodes in the second to-be-adjusted light emitting diodes are translated rightward, and the distance between the second to-be-adjusted light emitting diodes becomes larger, which indicates that the luminance display effect before adjustment corresponding to the dark spot area is darker.
Further, after step S15, the method further includes: acquiring third brightness display information of the corrected display; obtaining adjusted brightness information based on the third brightness display information; obtaining the duty ratio of the light emitting diode in the corrected display based on the adjusted brightness information; and configuring the working voltage of the light emitting diode in the corrected display by using the duty ratio.
It should be noted that, in the embodiment, the light emitting diodes that need to be configured with voltage are all the light emitting diodes in the corrected display, and a region with a uniform luminance display effect may be only required to use a preset duty ratio, and a region with a non-uniform luminance display effect needs to determine a new duty ratio based on the luminance display effect; the brightness control of the light-emitting diode is realized by adjusting the duty ratio of the light-emitting diode during working, so that the brightness of the corrected display is more uniform; for example, when the luminance in a certain region of the corrected display is high, the duty ratio may be adjusted to be smaller so that the luminance display is low, and when the luminance in a certain region of the corrected display is low, the duty ratio may be adjusted to be larger so that the luminance display is high. And meanwhile, duty ratios of the corrected displays are respectively configured, so that the luminance display of the corrected displays is uniform.
Further, the step of configuring the corrected operating voltage of the light emitting diodes in the display by using the duty ratio includes: and configuring the working voltage of the light emitting diode in the corrected display by utilizing the duty ratio and the pulse width modulation technology.
It can be understood that, in this embodiment, the brightness of the display is uniformly displayed by adjusting the duty ratio, and the configuration may be that the duty ratio of the display to be adjusted is directly performed, or the configuration is that the duty ratio of the display after adjustment is performed, or the configuration is that the duty ratio of the display after correction is performed, which is not limited in the present invention.
