Description

Technical Field

[0001] This application belongs to the field of electrical technology, specifically relating to an LED anti-crosslighting method, apparatus, device, and computer storage medium. Background Technology

[0002] LED light sources are cold light sources, meaning they emit light that does not contain ultraviolet rays, and they have advantages such as high efficiency, energy saving, and environmental friendliness. With continuous technological advancements, LED lights have been widely used in various fields. However, because LED lights still display a faint glow even when the switch is off, their application areas are somewhat limited.

[0003] In existing technologies, the current-limiting resistor of the scanning matrix in the LED light is increased so that the faint light is not displayed after the LED light is turned off; alternatively, the display film can be thickened to ensure that the faint light does not affect the user experience, without affecting normal lighting.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0055] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0057] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0058] LED light sources are cold light sources, meaning they emit light that does not contain ultraviolet rays. They offer advantages such as high efficiency, energy saving, and environmental friendliness. With continuous technological advancements, LED lights have been widely used in various fields. However, because LED lights still display a faint glow even when the switch is off, their application areas are somewhat limited.

[0059] In existing technologies, by increasing the current-limiting resistor of the scanning matrix in the LED, when the current passing through is too small, the faint light will not be displayed after the LED is turned off. Another method is to thicken the display film corresponding to the LED at the location where the faint light can be seen by the user, without affecting the normal lighting of the LED, so that the faint light will not be displayed under the obstruction of the display film, thus not affecting the user experience.

[0060] However, the above methods all come at the cost of brightness and cannot fundamentally solve the problem of LED lights still showing a faint glow after being turned off. Once the power of the entire circuit is increased, the brightness of the LED will increase, and users will still be able to observe the faint glow after the LED light is turned off.

[0061] The LED anti-crosslighting method provided in this application determines the cause of crosslighting after the LED is turned off by detecting the waveform between the COM and SEG terminals during LED matrix scanning. It also sets a delay program for abnormal areas to adjust the waveform in the abnormal areas to normal, so that the LED no longer produces dim light after being turned off. This method fundamentally solves the problem of LED crosslighting, improves user experience, and expands the application fields of LEDs.

[0062] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0063] Figure 1 This is the flow chart of the LED anti-crosslighting method provided in this application. Figure 1 .like Figure 1 As shown, the LED anti-crosslighting method provided in this embodiment includes:

[0064] S101: When scanning the LED matrix, acquire the candidate waveforms between multiple COM terminals and multiple SEG terminals generated on the LED matrix. The candidate waveforms generated between different COM terminals and SEG terminals are different.

[0065] The LED matrix is ​​used to indicate the composition of LEDs and can be controlled by a microcontroller to keep them on and off. The COM and SEG terminals are two sets of signals in the LED driver. COM can be considered the "common terminal," providing a stable power supply, while the SEG terminal can be considered the "scanning terminal." Different LEDs are lit by combining the COM and SEG terminals. The candidate waveform is used to indicate the waveform when the COM and SEG terminals are combined to light up the LED.

[0066] In this step, the LED matrix can be scanned in rows or columns. That is, the LED matrix is ​​scanned in rows or columns. In each scanning cycle, the LEDs in a row or column are selected and turned on or off.

[0067] Understandably, during LED matrix scanning, waveforms exist between the multiple COM terminals and multiple SEG terminals corresponding to the LED matrix. Within the same cycle, the waveforms between different COM terminals and SEG terminals occur at different times, meaning that different COM terminals and SEG terminals have different candidate waveforms.

[0068] S102: Based on multiple candidate waveforms, determine the abnormal region corresponding to the abnormal waveform.

[0069] Among them, the abnormal waveform is used to indicate that the waveform is the one that will produce a dimly lit area after the LED is turned off, and the abnormal area is used to indicate the area where the LED still displays a dimly lit area after it is turned off.

[0070] This embodiment aims to determine the cause of the faint glow phenomenon that persists even after the LED is turned off, and then take measures to correct it. Therefore, identifying the abnormal region corresponding to the abnormal waveform is a crucial step in this process. Multiple candidate waveforms include normal and abnormal waveforms. The region corresponding to the normal waveform is the normal region, meaning that the faint glow phenomenon after the LED is turned off will not occur in the normal region. The region corresponding to the abnormal waveform is the abnormal region, meaning that the faint glow phenomenon after the LED is turned off is the cause. Therefore, identifying the abnormal region is key to resolving the faint glow phenomenon after the LED is turned off.

[0071] S103: Set a delay program in the abnormal region and control the COM terminal corresponding to the abnormal waveform to perform scanning processing according to the delay program.

[0072] The delay program is used to instruct the COM end to delay the waveform formed by the COM end and the SEG end from the position where the delay program is set for a certain period of time.

[0073] Understandably, by analyzing the waveforms between the COM and SEG terminals, a delay program is set for the abnormal regions corresponding to the abnormal waveforms. If the delay program is successfully set, after the LED matrix is ​​rescanned, there will be no faint lighting after the LEDs are turned off; if the delay program fails to set, after the LED matrix is ​​rescanned, there will still be faint lighting after the LEDs are turned off.

[0074] The LED anti-crossing light method provided in this embodiment obtains candidate waveforms between multiple COM terminals and multiple SEG terminals generated on the LED matrix during LED matrix scanning. Different candidate waveforms are generated between different COM terminals and SEG terminals. Based on multiple candidate waveforms, abnormal regions corresponding to abnormal waveforms are determined. A delay program is set in the abnormal region, and the COM terminal corresponding to the abnormal waveform is controlled to perform scanning processing according to the delay program. This method fundamentally solves the LED crosstalk problem, improves user experience, and expands the application fields of LEDs.

[0075] Figure 2 This is the flow chart of the LED anti-crosslighting method provided in this application. Figure 2 .like Figure 2 As shown, in this embodiment... Figure 1 Based on the embodiments, the LED anti-crossing light method is described in detail. The LED anti-crossing light method shown in this embodiment includes:

[0076] S201: Obtain the theoretical waveforms generated between multiple COM terminals and multiple SEG terminals during LED matrix scanning.

[0077] One major issue is that the problem of LEDs producing a faint glow after being turned off is difficult to fundamentally solve due to distributed capacitance. In actual LED matrix scanning, it's rare for LEDs to not produce a faint glow after being turned off; therefore, the waveform between the COM and SEG terminals cannot be obtained through measurement. Consequently, the waveform between the COM and SEG terminals when LEDs do not produce a faint glow after being turned off can only be obtained theoretically through data inference.

[0078] S202: Based on the theoretical waveform, determine the theoretical correlation between the theoretical waveforms corresponding to two adjacent COM terminals.

[0079] The theoretical waveforms corresponding to two adjacent COM terminals can be the theoretical waveforms corresponding to COM1 and COM2 terminals. Furthermore, there is a theoretical correlation between the theoretical waveforms of COM1 and COM2 terminals.

[0080] Understandably, the first theoretical waveform between COM1 and SEG and the second theoretical waveform between COM2 and SEG are as follows: when the first theoretical waveform is high, the second theoretical waveform is low. The time when the first theoretical waveform drops to low is the same as the time when the second theoretical waveform rises to high. Both the first and second theoretical waveforms exhibit a stepped shape.

[0081] S203: When scanning the LED matrix, acquire the candidate waveforms between multiple COM terminals and multiple SEG terminals generated on the LED matrix. The candidate waveforms generated between different COM terminals and SEG terminals are different.

[0082] Step S203 is similar to step S101 above, and will not be described again here.

[0083] S204: Based on the multiple candidate waveforms and the correlation relationship, determine the abnormal region corresponding to the abnormal waveform.

[0084] The determination of abnormal regions must be based on the known normal regions. Therefore, after acquiring candidate waveforms with an oscilloscope, the candidate waveforms are compared with the theoretical waveforms to determine the abnormal waveforms, and then the abnormal regions corresponding to the abnormal waveforms are determined.

[0085] The first abnormal waveform between COM1 and SEG and the second abnormal waveform between COM2 and SEG are as follows: When the first abnormal waveform changes from a high level to a low level, the second abnormal waveform appears at a high level. The first abnormal waveform takes a certain amount of time to drop to a low level, unlike the theoretical waveform which changes abruptly. The second abnormal waveform also takes a certain amount of time to rise to a high level. Furthermore, the second abnormal waveform is easier to delay than the first abnormal waveform. Therefore, it can be set as an abnormal waveform, and the area corresponding to the abnormal waveform is the abnormal area.

[0086] S205: Obtain the duration of the abnormal region and use the duration as the target duration.

[0087] The duration of the duration of the difference between the theoretical waveform and the abnormal waveform indicates the length of time the theoretical waveform is at low voltage while the abnormal waveform is at high voltage. This duration can be used as a target duration to facilitate the setting of the duration in the subsequent delay program, thereby allowing the abnormal region to be directly adjusted into the normal region.

[0088] S206: Set the delay program in the abnormal area, and the delay duration of the delay program is the target duration.

[0089] Among them, by setting a delay program on the LED controller, the delay program is set in the abnormal region corresponding to the abnormal waveform at the COM terminal. Since there is more than one abnormal region, the delay program can be set in the initial abnormal region. The delay duration can be: the duration during which the second abnormal waveform appears at a high level while the first abnormal waveform does not drop to a low level within the same cycle.

[0090] S207: Control the COM terminal corresponding to the abnormal waveform to perform scanning processing according to the delay program.

[0091] Specifically, by setting a delay program for abnormal areas, if the LED matrix is ​​rescanned and no faint light is produced after the LEDs are turned off, it indicates that the delay program setting is complete. If faint light is still produced after the LEDs are turned off, the abnormal areas need to be re-identified and the delay program set again.

[0092] The LED anti-crossing light method provided in this embodiment obtains the theoretical waveforms generated between multiple COM terminals and multiple SEG terminals during LED matrix scanning. Based on the theoretical waveforms, it determines the theoretical correlation between the theoretical waveforms corresponding to two adjacent COM terminals. It then obtains candidate waveforms between multiple COM terminals and multiple SEG terminals generated on the LED matrix during scanning. Different candidate waveforms are generated between different COM terminals and SEG terminals. Based on the multiple candidate waveforms and the correlation, it determines the abnormal region corresponding to the abnormal waveform, obtains the duration of the abnormal region, and uses the duration as the target duration. A delay program is set within the abnormal region, with the delay duration being the target duration. The COM terminal corresponding to the abnormal waveform is then controlled to perform scanning processing according to the delay program. This method fundamentally solves the LED crosstalk problem, improves user experience, and expands the application areas of LEDs.

[0093] Figure 3 This is the flow chart of the LED anti-crosslighting method provided in this application. Figure 3 .like Figure 3 As shown, in this embodiment... Figure 2 Based on the embodiments, this embodiment provides a detailed explanation of determining the abnormal region corresponding to the abnormal waveform according to the plurality of candidate waveforms and the correlation relationship. The LED anti-crosslighting method shown in this embodiment includes:

[0094] S301: Determine whether the actual correlation between the first candidate waveform and the second candidate waveform among multiple candidate waveforms is consistent with the theoretical correlation, wherein COM1 corresponding to the first candidate waveform and COM2 corresponding to the second candidate waveform are adjacent.

[0095] The theoretical relationship between the first and second candidate waveforms is as follows: when the first theoretical waveform is high, the second theoretical waveform is low; the time point when the first theoretical waveform drops to low is the same as the time point when the second theoretical waveform rises to high; and both the first and second theoretical waveforms exhibit a stepped shape. The actual relationship between the first and second candidate waveforms is as follows: when the first abnormal waveform changes from high to low, the second abnormal waveform appears at a high level; the first abnormal waveform takes a period of time to drop to low, unlike the theoretical waveform which changes abruptly; the second abnormal waveform also takes a period of time to rise to high; and the second abnormal waveform is easier to delay, so it can be set as an abnormal waveform, and the region corresponding to the abnormal waveform is the abnormal region.

[0096] By comparing the actual correlation between the first and second candidate waveforms among multiple candidate waveforms with the theoretical correlation, it is determined whether the low level in the first candidate waveform corresponds to the high level in the second candidate waveform in the actual correlation, and whether the low level in the first candidate waveform should also correspond to the high level in the second candidate waveform in the theoretical correlation.

[0097] S302: When the actual correlation relationship and the theoretical correlation relationship are inconsistent, both the first candidate waveform and the second candidate waveform are determined to be abnormal candidate waveforms.

[0098] In the actual correlation, if the first candidate waveform is not at a low level and the second candidate waveform is at a high level, then it can be determined that both the first and second candidate waveforms are abnormal candidate waveforms.

[0099] S303: Based on the two abnormal candidate waveforms, determine the sub-abnormal regions that are not negatively correlated in the first candidate waveform and the second candidate waveform.

[0100] For abnormal candidate waveforms, when the first candidate waveform is not low, the region where the second candidate waveform is high is the sub-abnormal region. In other words, the region where the first candidate waveform and the second candidate waveform are not negatively correlated is the sub-abnormal region.

[0101] S304: The abnormal candidate waveform with a high level in the sub-abnormal region is taken as the abnormal waveform, and the sub-abnormal region corresponding to the abnormal waveform is taken as the abnormal region.

[0102] The reason why abnormal candidate waveforms that are at a high level in the abnormal region are considered abnormal waveforms is that a delay program can be set for the abnormal region that is at a high level, while setting a program for the region that is neither at a low level nor at a high level is more complicated.

[0103] The LED anti-crossing method provided in this embodiment determines whether the actual correlation between a first candidate waveform and a second candidate waveform among multiple candidate waveforms is consistent with the theoretical correlation. Specifically, if COM1 corresponding to the first candidate waveform and COM2 corresponding to the second candidate waveform are adjacent, and the actual correlation is inconsistent with the theoretical correlation, then both the first and second candidate waveforms are determined to be abnormal candidate waveforms. Based on these two abnormal candidate waveforms, a sub-abnormal region that is not negatively correlated is determined between the first and second candidate waveforms. The abnormal candidate waveform with a high level in the sub-abnormal region is taken as the abnormal waveform, and the sub-abnormal region corresponding to the abnormal waveform is taken as the abnormal region. This method fundamentally solves the LED crosstalk problem, improves user experience, and expands the application areas of LEDs.
