Based on the above hardware architecture, an embodiment of the method for increasing the signal transmission rate of the present application is proposed.

Referring to FIG. 2, a schematic flowchart of an embodiment of a method for increasing a signal transmission rate of the present application, the method for increasing a signal transmission rate includes:

Step S10, encoding the binary data to be transmitted in the controller into a voltage signal;

After the display panel is powered off, the controller reads the data directly from the memory. The controller needs to send the relevant output permission, latch input, line start, and polarity reversal signals to the driver, and the transfer rate between the controller and the memory The transmission rate is generally between 100k~200kHz, and the panel has been in a black screen during this period. If the transmission rate between the controller and the memory can be increased, the time for the panel to be black can be shortened and the use effect of the panel can be improved. .

In the exemplary technology, when the controller transmits binary data to the memory, different data will only be reflected in the time and two voltage signals, that is, the voltage signal transmitted in a time period can only represent one binary data, in this application The method for increasing the signal transmission rate should be set in the display panel. It can be understood that the method for increasing the signal transmission rate can also be set for other terminals, such as mobile phones and computers, which are not limited herein. The encoder controller of the display panel is provided with an encoder, and the memory of the display panel is provided with a decoder that matches the encoder. The controller is connected to the memory signal by passing Binary data is encoded into corresponding voltage signals, so that the voltage signal transmitted by the controller to the memory can represent multiple binary data. In this application, the binary data to be transmitted in the controller is reflected in the time and more than four voltage signals, This improves the efficiency of the controller to transfer binary data to the memory. For example, in the exemplary technology, 0V represents 0 in binary data, 3.3V represents 1 in binary data, and in this application, 0V represents 00 in binary data, and 1V represents 01, 2V in binary data. It represents 10 in binary data, and 3V represents 11 in binary data.

In step S20, the voltage signal is transmitted to the memory, and when the decoder in the memory detects the voltage signal, the voltage signal is decoded into binary data.

The memory is provided with a decoder that matches the encoder. The display panel passes the voltage signal encoded by the controller to the memory. When the decoder in the memory detects the voltage signal, it decompresses the detected voltage signal into the corresponding binary Data, thus completing the data transmission from the controller to the memory, the voltage signal encoded by the controller is transmitted to the memory on the SDA (Serial Data Bus) line.

It should be noted that when the controller transmits binary data to the memory, it often takes the eight binary data as a batch, and then passes the eight binary data to the memory to determine whether the memory has received the eight binary data. After confirming that the memory receives the batch of binary data, the controller sends the next batch of binary data to the memory.

In the technical solution provided by this embodiment, by setting an encoder in the controller, and then encoding the binary data to be transmitted in the controller into a corresponding voltage signal, the binary data to be transmitted is composed of more than four voltage signals It means that when the decoder detects a voltage signal, it decodes the voltage signal into corresponding binary data, and one voltage signal corresponds to multiple binary data. Compared with the exemplary technology, the voltage signal transmitted by the controller to the memory represents only one binary data at the same time, while the voltage signal transmitted in this application represents multiple binary data, thereby improving the data between the controller and the memory The transmission rate of the computer, which in turn reduces the black screen time of the display panel during startup, improves the experience of setting the panel.

Referring to FIG. 3, FIG. 3 is another embodiment of the air conditioner control method. Based on the first embodiment, the step S10 includes:

Step S11, obtaining the grouping rule of the encoder;

Step S12: Group the binary data to be transmitted according to the grouping rule to obtain sub-data;

Step S13: Encode the sub-data to generate a corresponding voltage signal.

In the technical solution provided in this embodiment, the display panel first obtains the grouping rules of the encoder, that is, the data to be transmitted in the controller is distinguished according to several data as a group, and the binary data to be transmitted can be divided after the grouping rules are determined Group to obtain the sub-data to be transmitted. For example, if the grouping rule is to use two binary data as a group, the sub-data obtained after grouping the binary data to be transmitted includes: 00, 01, 10, 11, and it should be noted that in the process of grouping the sub-data , According to the order of the binary data to be transmitted, the two adjacent binary data as a group of sub-data. Encode the sub-data to generate the corresponding voltage signal. After the voltage signal is transmitted to the memory, the memory decodes and restores it to the corresponding binary data, thereby improving the transmission efficiency between the controller and the memory. It should be noted that each voltage signal is transmitted to the memory in the order of the sub-data in the binary data.

It should be noted that the grouping rule includes the number of binary data in the sub-data, for example, each sub-data contains two binary data or three binary data or multiple binary data, etc., which is not limited herein.

Optionally, in step S12, the step of grouping the binary data to be transmitted according to the grouping rule to obtain sub-data includes: determining the encoding frequency of the encoder according to the grouping rule; and the binary to be transmitted according to the encoding frequency The data is grouped to obtain sub-data. In this application, after the encoder determines the grouping rules, it determines the frequency of the encoder to encode the binary data according to the grouping rules, adjusts the working frequency of the encoder to the encoding frequency, and then the encoder groups the binary data to be transmitted Get subdata. It should be noted that the encoding frequency includes at least one of 2 times frequency and 3 times frequency, where 2 times frequency means that the sub data includes two binary data, and the signal transmission rate between the controller and the memory is The single binary data is transmitted twice; the triple frequency means that the sub-data includes three binary data, and the signal transmission rate between the controller and the memory is three times that of the single binary data transmission. It can be understood that the coding frequency may also be other high-frequency frequencies, which is not limited herein.

Optionally, in step S13, the step of encoding the sub-data to generate a corresponding voltage signal includes: obtaining a relationship table between the sub-data and the voltage signal; generating the sub-data according to the relationship table Corresponding voltage signal. In this application, the encoder obtains a relationship table between the sub data and the voltage signal, and generates a voltage signal corresponding to the sub data according to the relationship table. For example, when the encoder uses 2 times the frequency for encoding, the sub-data contains two binary data. At this time, the relationship between the sub-data and the voltage signal is as follows:

Subdata	00	01	10	11
Voltage signal (V)	0	1	2	3

When the encoder uses 3 times the frequency for encoding, the sub-data contains three binary data. At this time, the relationship between the sub-data and the voltage signal is as follows

Subdata	000	001	010	011	100	101	110	111
Voltage signal (V)	0.0	0.5	1.0	1.5	2.0	2.5	3.0	3.5

It can be understood that the voltage signal is set by the user, as long as the voltage signal corresponding to each sub-data is inconsistent, no limitation is made here.

It should be noted that the relationship table between the sub-data and the voltage signal may be preset for the controller, or determined by the worker according to the actual use of the panel.

Optionally, after the step S10, that is, the step of encoding the binary data to be transmitted in the controller into a voltage signal, the method further includes: sending the grouping rule to the memory. In this application, the voltage signal and the grouping rule are preferably sent to the memory together. The decoder in the memory decodes the voltage signal according to the grouping rule to restore the voltage signal to the corresponding binary data. It can be understood that the grouping rule It can be preset in the encoder and decoder, so that there is no need to send the grouping rules to the memory without the controller. It can be understood that the relationship table between the sub-data and the voltage signal can be preset in the encoder and the decoder, or the relationship table between the sub-data and the voltage signal and the grouping rules are The encoder is sent to the decoder in the memory.

Optionally, after the step of grouping the binary data to be transmitted according to the grouping rule to obtain sub-data, the method further includes: when the number of binary data to be transmitted does not satisfy the grouping rule, adding a binary at a preset position Number, so that the number of the binary data meets the grouping rule. In this application, when the number of binary data remaining after grouping of data to be transmitted does not meet the grouping requirements, the encoder adds a binary number at a preset position, which may be the first of the sub-data The position or the last position, so that the number of binary data satisfies the grouping rule, so that the binary data to be transmitted is divided into several sub-data. For example, when the grouping rule is a group of three binary data, if only two binary data are left at the end, a binary number 1 or 0 can be added at the end, so that the binary data to be transmitted can be divided into sub data. It should be noted that after the encoder decompresses the voltage signal, the binary data added at the preset position should be eliminated to avoid errors in the signal transmitted between the controller and the memory.
