技术领域technical field
本发明涉及显示技术领域，尤其涉及公共电压补偿系统及其控制方法、显示设备及存储介质。The invention relates to the field of display technology, in particular to a common voltage compensation system and a control method thereof, a display device and a storage medium.
背景技术Background technique
在现有的显示产品的研发设计以及生产过程中，目前出现有关于字符串扰问题较为严重，在问题解析和改善过程中，发现这种现象非常普遍，因此产品设计上不得不通过增加运算放大器(OperationalAmplifier，OP)提供公共电压(Common Voltage，Vcom)补偿来改善串扰问题。由于每个源极芯片可以有多个公共电压补偿接受通道，而显示产品的远近端的横向串扰和竖向串扰的情况又有区别，因此需要针对不同位置的源极芯片的不同通道进行相适应的公共电压补偿设置。In the R&D, design and production process of the existing display products, the problem of string interference is relatively serious. In the process of problem analysis and improvement, it is found that this phenomenon is very common. Therefore, the product design has to be increased by adding an operational amplifier ( OperationalAmplifier, OP) provides common voltage (Common Voltage, Vcom) compensation to improve the crosstalk problem. Since each source chip can have multiple common voltage compensation receiving channels, and the horizontal crosstalk and vertical crosstalk at the far and near ends of the display product are different, it is necessary to adapt to different channels of the source chip at different positions. Common voltage compensation setting.
目前，从不配置OP，到配置二通道OP、四通道OP、甚至于两个四通道OP的状况，都是通过增加OP的公共电压补偿输出来实现更为精细的补偿效果，补偿越精准，显示效果就越好。然而，运算放大器集成电路中比较常用的运算放大器是四通道输出OP，考虑到功耗和成本的问题，不能仅为了提升显示效果而追求使用有更多输出通道的OP；同理，为了提升显示效果而使用多个OP来进行公共电压补偿的方案同样不可行。At present, from no configuration of OP, to the configuration of two-channel OP, four-channel OP, or even two four-channel OP, the compensation effect is achieved by increasing the common voltage compensation output of the OP. The more accurate the compensation, the better the compensation effect. The better the display. However, the more commonly used operational amplifier in operational amplifier integrated circuits is the four-channel output OP. Considering the power consumption and cost, it is not possible to pursue the use of an OP with more output channels just to improve the display effect; similarly, in order to improve the display The scheme of using multiple OPs for common voltage compensation due to the effect is also not feasible.
但是，在仅有一个四通道输出OP的情况下，在构建了一种固定的公共电压补偿方式后，例如将每颗源极芯片的各通道公共电压补偿倍数都设置一致，则可能会不满足实际需要，无法达到明显的串扰改善效果，即此种节省成本的公共电压补偿方式存在改善效果不理想却不易进行更正的风险。However, in the case of only one four-channel output OP, after constructing a fixed common voltage compensation method, for example, setting the common voltage compensation multiples of each channel of each source chip to be the same, it may not be satisfied Due to actual needs, it is impossible to achieve an obvious crosstalk improvement effect, that is, there is a risk that this cost-saving common voltage compensation method has an unsatisfactory improvement effect but is not easy to correct.

作为一个示例，以MNT(Monitor，主要是指台式电视的显示器)产品为例，该类产品中最常使用的是6COF和4通道OP进行公共电压补偿，即公共电压补偿系统包括一个四通道运算放大器和六个源极芯片，且每个源极芯片中均包括四个公共电压补偿反馈接受引脚，为便于理解，本实施例提供如图2所示的应用场景示意图，由图2可知，将六个源极芯片依次命名为COF1、COF2、COF3、COF4、COF5和COF6，COF1的四个公共电压补偿反馈接受引脚分别为1-1、1-2、1-3和1-4，COF2的四个公共电压补偿反馈接受引脚分别为2-1、2-2、2-3和2-4，COF3的四个公共电压补偿反馈接受引脚分别为3-1、3-2、3-3和3-4，COF4的四个公共电压补偿反馈接受引脚分别为4-1、4-2、4-3和4-4，COF5的四个公共电压补偿反馈接受引脚分别为5-1、5-2、5-3和5-4，COF6的四个公共电压补偿反馈接受引脚分别为6-1、6-2、6-3和6-4，四通道运算放大器即图2中op，其四个输出通道分别为L1、L2、R1和R2，假设在产品封装时op和各COF引脚之间的连接关系为：L1输出对应到1-1引脚，L2输出对应到2-4引脚，R2输出对应到5-1引脚，R1输出对应到6-4引脚，若将COF1的1-2、1-3、1-4和COF2的2-1、2-2、2-3和2-4以及COF3的3-1、3-2、3-3和3-4之间的连接开关闭合，则L1单独给COF1的1-1提供公共电压补偿，L2给COF1的1-2、1-3、1-4引脚以及COF2和COF3的全部引脚提供公共电压补偿；若将COF4的4-1、4-2、4-3、4-4和COF5的2-1、2-2、2-3和2-4以及COF6的6-1、6-2、6-3之间的连接开关闭合，则COF4和COF5的全部引脚以及COF6的6-1、6-2、6-3接受来自R2的公共电压补偿，COF6的6-4单独接受来自R1的公共电压补偿。As an example, take MNT (Monitor, mainly refers to the display of desktop TV) products as an example, the most commonly used in this type of product is 6COF and 4-channel OP for common voltage compensation, that is, the common voltage compensation system includes a four-channel operation Amplifier and six source chips, and each source chip includes four common voltage compensation feedback receiving pins. For ease of understanding, this embodiment provides a schematic diagram of an application scenario as shown in FIG. 2. It can be seen from FIG. 2 that The six source chips are named COF1, COF2, COF3, COF4, COF5 and COF6 in turn, and the four common voltage compensation feedback receiving pins of COF1 are 1-1, 1-2, 1-3 and 1-4 respectively, The four common voltage compensation feedback receiving pins of COF2 are respectively 2-1, 2-2, 2-3 and 2-4, and the four common voltage compensation feedback receiving pins of COF3 are 3-1, 3-2, 3-3 and 3-4, the four public voltage compensation feedback receiving pins of COF4 are 4-1, 4-2, 4-3 and 4-4 respectively, and the four public voltage compensation feedback receiving pins of COF5 are respectively 5-1, 5-2, 5-3 and 5-4, the four common voltage compensation feedback receiving pins of COF6 are 6-1, 6-2, 6-3 and 6-4 respectively, the four-channel operational amplifier is In Figure 2, op, its four output channels are L1, L2, R1 and R2 respectively, assuming that the connection relationship between op and each COF pin in the product package is: L1 output corresponds to 1-1 pin, L2 output Corresponds to 2-4 pins, R2 output corresponds to 5-1 pins, R1 output corresponds to 6-4 pins, if 1-2, 1-3, 1-4 of COF1 and 2-1, 2-2, 2-3 and 2-4 and the connection switch between 3-1, 3-2, 3-3 and 3-4 of COF3 are closed, then L1 alone provides common voltage compensation for 1-1 of COF1, L2 provides common voltage compensation for 1-2, 1-3, 1-4 pins of COF1 and all pins of COF2 and COF3; if 4-1, 4-2, 4-3, 4-4 and When the connection switch between 2-1, 2-2, 2-3 and 2-4 of COF5 and 6-1, 6-2 and 6-3 of COF6 is closed, all pins of COF4 and COF5 and 6 of COF6 -1, 6-2, 6-3 accept common voltage compensation from R2, and 6-4 of COF6 accepts common voltage compensation from R1 alone.
此外，本实施例中各引脚之间的连接开关存在替代方案，即在各引脚之间引出连接线然后预留焊盘，根据实际需要选择上件电阻来连通，同样能够使得连通的各引脚接受到相同倍数的公共电压补偿。In addition, there is an alternative solution for the connection switch between the pins in this embodiment, that is, lead out the connecting wires between the pins and reserve pads, and select the resistance of the upper part to connect according to actual needs, which can also make the connected pins are compensated by the same multiple of the common voltage.
本实施例提出一种公共电压补偿系统，在所述公共电压补偿系统中包括运算放大器和多个源极芯片，部分源极芯片与运算放大器电性连接，用于接收运算放大器输出的公共电压补偿，本发明在各源极芯片的各公共电压补偿反馈接受引脚两两之间均设置了连接开关，能够通过改变各连接开关的开闭状态进而改变各公共电压补偿反馈接受引脚之间的连接状态，进而改变源极芯片的不同通道的公共电压补偿倍数，在不增加运算放大器和不改变运算放大器与已连接的源极芯片之间的连接方式的情况下，实现了对源极芯片不同通道的公共电压补偿倍数的灵活调整，克服了现有技术中固定的公共电压补偿方式存在的技术缺陷。This embodiment proposes a common voltage compensation system. The common voltage compensation system includes an operational amplifier and a plurality of source chips, and some source chips are electrically connected to the operational amplifier for receiving the common voltage compensation output by the operational amplifier.

本实施例中，所述公共电压补偿系统的控制方法包括：In this embodiment, the control method of the public voltage compensation system includes:
步骤S10，接收公共电压补偿调节请求；Step S10, receiving a public voltage compensation adjustment request;
需要说明的是，本实施例应用于如上所述的公共电压补偿系统，该系统中还可以包括处理器，处理器可以根据接收到的公共电压补偿调节请求对公共电压补偿系统中的各连接开关的开闭状态进行调整，该公共电压补偿调节请求可以是由负责对系统进行调试或测试的实验人员经由工控机、平板电脑或便携式计算机等终端设备发起的调节信号。It should be noted that this embodiment is applied to the public voltage compensation system as described above, and the system may further include a processor, and the processor may switch each connection switch in the public voltage compensation system according to the received public voltage compensation adjustment request. The opening and closing state of the system is adjusted, and the public voltage compensation adjustment request can be an adjustment signal initiated by the experimenter responsible for debugging or testing the system via terminal equipment such as an industrial computer, a tablet computer, or a portable computer.
步骤S20，根据所述公共电压补偿调节请求获取各所述源极芯片中各所述公共电压补偿反馈接受引脚的触点状态；Step S20, obtaining the contact state of each of the common voltage compensation feedback receiving pins in each of the source chips according to the common voltage compensation adjustment request;
需要说明的是，当接收到公共电压补偿调节请求后，处理器会先获取各所述源极芯片中各所述公共电压补偿反馈接受引脚的触点状态，以根据所有引脚的触点状态来确定当前的公共电压补偿方式是何种方式，是否符合公共电压补偿调节请求的目标要求，同时由于有的引脚已与运算放大器的输出通道建立连接，有的引脚可能并不需要使用故而会设置为NC(normally close，在不通电时处于闭合导通状态的触点，通常称为常闭触点)状态，若直接根据公共电压补偿调节请求将常闭触点与常开触点之间的连接开关闭合，却不调整常闭触点的状态，显然也不能完成公共电压补偿调节请求中设定的目标。It should be noted that, after receiving the common voltage compensation adjustment request, the processor will first obtain the contact state of each of the common voltage compensation feedback acceptance pins in each of the source chips, so as to State to determine the current public voltage compensation method, whether it meets the target requirements of the public voltage compensation adjustment request, and because some pins have been connected to the output channel of the operational amplifier, some pins may not need to be used Therefore, it will be set to NC (normally close, a contact that is in a closed conduction state when it is not energized, usually called a normally closed contact) state. If the normally closed contact and the normally open contact are directly adjusted according to the public voltage compensation adjustment request The connection switch between them is closed, but the state of the normally closed contact is not adjusted, and obviously the goal set in the public voltage compensation adjustment request cannot be completed.
基于此，在一种可行的实施例中，所述公共电压补偿调节请求包括边缘同步请求，上述的步骤S20可以包括：Based on this, in a feasible embodiment, the common voltage compensation adjustment request includes an edge synchronization request, and the above step S20 may include:
步骤A20，根据所述边缘同步请求获取各所述源极芯片中位于边缘侧的各所述公共电压补偿反馈接受引脚的触点状态。Step A20, acquiring the contact state of each of the common voltage compensation feedback accepting pins on the edge side of each of the source chips according to the edge synchronization request.
本实施例中，边缘同步请求指的是将各源极芯片中位于边缘侧的各所述公共电压补偿反馈接受引脚的公共电压补偿倍数进行同步，因此，需要先获取各源极芯片两侧的引脚的触点状态。In this embodiment, the edge synchronization request refers to synchronizing the common voltage compensation multiples of the common voltage compensation feedback receiving pins on the edge side of each source chip. Therefore, it is necessary to first obtain the The contact state of the pin.
作为一个示例，本实施例可结合图2进行理解，若将本实施例中的方案应用于图2所示的应用场景，则需要获取触点状态的引脚为1-1、1-4、2-1、1-4、3-1、3-4、4-1、4-4、5-1、5-4、6-1以及6-4。As an example, this embodiment can be understood in conjunction with FIG. 2. If the solution in this embodiment is applied to the application scenario shown in FIG. 2, the pins that need to obtain the contact state are 1-1, 1-4, 2-1, 1-4, 3-1, 3-4, 4-1, 4-4, 5-1, 5-4, 6-1, and 6-4.
进一步地，在另一种可行的实施例中，所述公共电压补偿调节请求还包括同模同步请求，上述的步骤S20还可以包括：Further, in another feasible embodiment, the common voltage compensation adjustment request also includes a same-mode synchronization request, and the above step S20 may also include:
步骤B20，根据所述同模同步请求获取各所述源极芯片中的各所述公共电压补偿反馈接受引脚的触点状态。Step B20, acquiring the contact state of each of the common voltage compensation feedback accepting pins in each of the source chips according to the same-mode synchronization request.
本实施例中，同模同步请求指的是将各源极芯片中的各所述公共电压补偿反馈接受引脚的公共电压补偿倍数进行同步，也就是说，属于同一源极芯片的各引脚的公共电压补偿倍数需要进行同步，而不属于源极芯片的各引脚的公共电压补偿倍数则无需进行同步，因此，需要先获取系统中所有公共电压补偿反馈接受引脚的触点状态。In this embodiment, the same-mode synchronization request refers to synchronizing the common voltage compensation multiples of the common voltage compensation feedback receiving pins in each source chip, that is, each pin belonging to the same source chip The common voltage compensation multiples of the pins that do not belong to the source chip do not need to be synchronized. Therefore, it is necessary to obtain the contact status of all common voltage compensation feedback receiving pins in the system.
步骤S30，根据所述公共电压补偿调节请求和各所述触点状态改变各所述公共电压补偿反馈接受引脚之间的连接状态。Step S30, changing the connection state between each of the common voltage compensation feedback accepting pins according to the common voltage compensation adjustment request and each of the contact states.
应理解的是，在已获知需要获知的引脚的触点状态之后，若触点状态为常闭状态，则先将其调整为常开状态后，再根据公共电压补偿调节请求对需要建立连接的各引脚之间的连接开关进行开闭状态的调整，即可完成公共电压补偿调节请求。It should be understood that after knowing the contact state of the pin that needs to be known, if the contact state is normally closed, first adjust it to the normally open state, and then establish a connection according to the public voltage compensation adjustment request. The connection switch between the pins of each pin can be adjusted to open and close the state, and the public voltage compensation adjustment request can be completed.
基于此，在一种可行的实施例中，上述的步骤S30可以包括：Based on this, in a feasible embodiment, the above step S30 may include:
步骤A30，当各所述源极芯片中位于边缘侧的各所述公共电压补偿反馈接受引脚的触点状态为常开状态时，将位于同一边缘侧的各所述公共电压补偿反馈接受引脚两两之间的各所述连接开关闭合，以使位于同一边缘侧的各所述公共电压补偿反馈接受引脚相连。Step A30, when the contact state of each of the common voltage compensation feedback accepting pins located on the edge side in each of the source chips is normally open, switch each of the common voltage compensation feedback accepting pins located on the same edge side to The connection switches between two pins are closed, so that the common voltage compensation feedback receiving pins located on the same edge side are connected.
可以理解的是，该步骤A30是对应于上述步骤A20之后的步骤，即在公共电压补偿调节请求为边缘同步请求时的一个分支步骤，此时若各所述源极芯片中位于边缘侧的各所述公共电压补偿反馈接受引脚的触点状态为常开状态，则无需对触点状态进行更改，直接将位于同一边缘侧的各所述公共电压补偿反馈接受引脚两两之间的各所述连接开关闭合，即可完成边缘同步请求。It can be understood that this step A30 corresponds to the step after the above step A20, that is, a branch step when the common voltage compensation adjustment request is an edge synchronization request. At this time, if each source chip located on the edge side If the contact state of the common voltage compensation feedback accepting pin is normally open, there is no need to change the contact state, and each of the common voltage compensation feedback accepting pins located on the same edge side is directly connected to each other. When the connection switch is closed, the edge synchronization request can be completed.
此外，对于上述步骤A30，该常开状态也可以是常闭状态，若存在需要调整公共电压补偿倍数的引脚的触点状态为常闭状态，则增加一将其调整为常开状态的步骤即可。In addition, for the above step A30, the normally open state can also be normally closed state, if the contact state of the pin that needs to adjust the common voltage compensation multiple is normally closed state, then add a step of adjusting it to the normally open state That's it.
作为一个示例，若将本实施例中的方案应用于图2所示的应用场景，则将1-1、2-1、3-1两两之间的连接开关闭合，使得1-1、2-1、3-1相连接，将4-1、5-1、6-1两两之间的连接开关闭合，使得4-1、5-1、6-1相连接，将1-4、2-4、3-4两两之间的连接开关闭合，使得1-4、2-4、3-4相连接，将4-4、5-4、6-4两两之间的连接开关闭合，使得4-4、5-4、6-4相连接，那么L1就给1-1、2-1、3-1提供相同倍数的公共电压补偿，L2就给1-4、2-4、3-4提供相同倍数的公共电压补偿，R2就给4-1、5-1、6-1提供相同倍数的公共电压补偿，R1就给4-4、5-4、6-4提供相同倍数的公共电压补偿。As an example, if the solution in this embodiment is applied to the application scenario shown in Figure 2, the connection switches between 1-1, 2-1, and 3-1 are closed, so that 1-1, 2 -1, 3-1 are connected, the connection switch between 4-1, 5-1, 6-1 is closed, so that 4-1, 5-1, 6-1 are connected, and 1-4, The connection switch between 2-4, 3-4 is closed, so that 1-4, 2-4, 3-4 are connected, and the connection switch between 4-4, 5-4, 6-4 is closed. Closed so that 4-4, 5-4, 6-4 are connected, then L1 will provide 1-1, 2-1, 3-1 with the same multiple of common voltage compensation, and L2 will provide 1-4, 2-4 , 3-4 provide the same multiple of public voltage compensation, R2 provides the same multiple of public voltage compensation for 4-1, 5-1, 6-1, R1 provides the same multiple of public voltage compensation for 4-4, 5-4, 6-4 Multiple common voltage compensation.
进一步地，在另一种可行的实施例中，上述的步骤S30还可以包括：Further, in another feasible embodiment, the above step S30 may also include:
步骤B30，当各所述源极芯片中的各所述公共电压补偿反馈接受引脚的触点状态包括常闭状态时，将处于常闭状态的各所述公共电压补偿反馈接受引脚调整至常开状态，并将属于同一所述源极芯片的各所述公共电压补偿反馈接受引脚两两之间的各所述连接开关闭合，以使属于同一所述源极芯片的各所述公共电压补偿反馈接受引脚相连。Step B30, when the contact state of each of the common voltage compensation feedback accepting pins in each of the source chips includes a normally closed state, adjusting each of the common voltage compensation feedback accepting pins in the normally closed state to normally open state, and each of the connection switches between each of the common voltage compensation feedback accepting pins belonging to the same source chip is closed, so that each of the common voltages belonging to the same source chip Connected to voltage compensation feedback accept pin.
可以理解的是，该步骤B30是对应于上述步骤B20之后的步骤，即在公共电压补偿调节请求为同模同步请求时的一个分支步骤，此时若各所述源极芯片中的各所述公共电压补偿反馈接受引脚的触点状态包括常闭状态，说明可能是部分引脚处于常闭状态，则需先将处于常闭状态的这部分引脚的触点状态更改为常开状态，然后在将属于同一源极芯片的各所述公共电压补偿反馈接受引脚两两之间的各所述连接开关闭合，即可完成该同模同步请求。It can be understood that this step B30 corresponds to the step after the above step B20, that is, a branch step when the common voltage compensation adjustment request is a synchronous request of the same mode. At this time, if each of the said source chips The contact state of the public voltage compensation feedback receiving pin includes the normally closed state, indicating that some pins may be in the normally closed state, and you need to first change the contact state of these pins in the normally closed state to the normally open state. Then, the same-mode synchronization request can be completed by closing each of the connection switches between each of the common voltage compensation feedback receiving pins belonging to the same source chip.
作为一个示例，若将本实施例中的方案应用于图2所示的应用场景，则将COF1中的各引脚1-1、1-2、1-3和1-4两两之间的连接开关闭合，使得COF1中的1-1、1-2、1-3和1-4均接受来自L1的公共电压补偿倍数，将COF2中的各引脚2-1、2-2、2-3和2-4两两之间的连接开关闭合，使得COF2中的2-1、2-2、2-3和2-4均接受来自L2的公共电压补偿倍数，将COF5中的各引脚5-1、5-2、5-3和5-4两两之间的连接开关闭合，使得COF5中的5-1、5-2、5-3和5-4均接受来自R2的公共电压补偿倍数，将COF6中的各引脚6-1、6-2、6-3和6-4两两之间的连接开关闭合，使得COF6中的6-1、6-2、6-3和6-4均接受来自R1的公共电压补偿倍数，由于COF3和COF4并未接受来自op的公共电压补偿，故而对于COF3和COF4，可以先将COF3或COF4中的各引脚两两之间的连接开关闭合，再将其与COF1、COF2、COF5或COF6中任一源极芯片的任一引脚之间的连接开关闭合，即可使得COF3或COF4中的各引脚接受的公共电压补偿倍数达成一致。As an example, if the solution in this embodiment is applied to the application scenario shown in FIG. The connection switch is closed so that 1-1, 1-2, 1-3 and 1-4 in COF1 all receive the common voltage compensation multiple from L1, and each pin 2-1, 2-2, 2- The connection switch between 3 and 2-4 is closed, so that 2-1, 2-2, 2-3 and 2-4 in COF2 all receive the common voltage compensation multiple from L2, and each pin in COF5 The connection switches between 5-1, 5-2, 5-3 and 5-4 are closed, so that 5-1, 5-2, 5-3 and 5-4 in COF5 all receive the common voltage from R2 Compensation multiple, the connection switch between each pin 6-1, 6-2, 6-3 and 6-4 in COF6 is closed, so that 6-1, 6-2, 6-3 and 6-4 all accept the public voltage compensation multiple from R1, since COF3 and COF4 do not accept the public voltage compensation from op, so for COF3 and COF4, you can first connect the pins of COF3 or COF4 between two pairs Close the switch, and then close the connection switch between it and any pin of any source chip in COF1, COF2, COF5 or COF6, so that the common voltage compensation multiplier accepted by each pin in COF3 or COF4 can be achieved unanimous.
