In the prior art, for controller when transmitting binary data to memory, different data can only be embodied in the time
On two voltage signals, i.e. the voltage signal transmitted in a period can only represent a binary data, in the application
In, the method for promotion signal transmission rate is applied in display panel, it is to be understood that the side of the promotion signal transmission rate
Method can be used for other terminals, such as mobile phone, computer, herein with no restrictions.It is equipped in the Coder controller of display panel
Encoder is equipped with the decoder to match with the encoder, the controller and the storage in the memory of display panel

It should be noted that controller often makees eight binary data when transmitting binary data to memory
For a batch, then after this eight binary data are transferred to memory, determine whether memory receives this eight binary systems
Data, after determining that memory receives this batch of binary data, controller sends next group binary data to memory again.
In technical solution provided in this embodiment, by the way that encoder is arranged in the controller, then by controller to
The binary data coding of transmission is at corresponding voltage signal, so that binary data to be transmitted is believed by more than four voltages
It number represents, when decoder detects voltage signal, voltage signal is decoded into corresponding binary data, a voltage signal
Corresponding multiple binary data.Compared with prior art, in the same time, generation in the voltage signal that controller is transmitted to memory
One binary data of table, and the voltage signal transmitted in the application represents multiple binary data, to improve controller

Step S13 encodes the subdata to generate corresponding voltage signal.
In technical solution provided in this embodiment, display panel obtains the rule of classification of encoder first, i.e., by controller
In data to be transmitted be one group according to several data and distinguish, can be by binary system to be transmitted after determining rule of classification
Data are grouped, to obtain subdata to be transmitted.For example, if rule of classification is using two binary data as one
Group includes: then 00,01,10,11 to the subdata obtained after binary data to be transmitted grouping, it should be noted that dividing
During group obtains subdata, according to binary data sequence to be transmitted using two adjacent binary data as one group
Subdata.Subdata is encoded, to generate corresponding voltage signal, after voltage signal is transmitted to memory later, by
Memory, which is decoded, is reduced into corresponding binary data, to improve the efficiency of transmission between controller and memory.
It should be noted that each voltage signal is according to sequential delivery of the subdata in binary data to the memory.
It should be noted that the rule of classification includes the number of binary data in subdata, for example, each subdata
In containing there are two binary data or three binary data or multiple binary data etc., this is not restricted.
Optionally, the step S12 is grouped to obtain son according to the rule of classification to binary data to be transmitted
The step of data, comprising: the coding frequency of encoder is determined according to the rule of classification；According to the coding frequency to be transmitted
Binary data be grouped to obtain subdata.In the application, after encoder determines rule of classification, just advised according to grouping
It then determines the frequency that encoder encodes binary data, the working frequency of encoder is adjusted to coding frequency, then
Binary data to be transmitted is grouped to obtain subdata by encoder.It should be noted that the coding frequency includes 2
At least one of overtones band and 3 overtones bands, wherein 2 overtones bands refer to that subdata includes two binary data, control at this time
Signal transmission rate is single binary number according to twice transmitted between device and memory；3 overtones bands refer to subdata packet
Three binary data are included, signal transmission rate is single binary number according to being transmitted between controller and memory at this time
Three times.It is understood that coding frequency can also be other high overtones bands, this is not restricted.
Optionally, the step S13, the step of subdata is encoded to generate corresponding voltage signal packet
It includes: obtaining the relationship table between subdata and voltage signal；It is right that the subdata institute is generated according to the relationship table
The voltage signal answered.In this application, encoder obtains the relationship table between subdata and voltage signal, and according to relationship
The table of comparisons generates the corresponding voltage signal of subdata.For example, when encoder is encoded using 2 overtones bands, in subdata
Containing there are two binary data, at this point, the relationship table between subdata and voltage signal is as follows:
| Subdata | 00 | 01 | 10 | 11 |
| Voltage signal (V) | 0 | 1 | 2 | 3 |
When encoder is encoded using 3 overtones bands, containing there are three binary data in subdata, at this point, subdata
Relationship table between 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 is understood that voltage signal is set by the user, as long as voltage signal corresponding to each subdata is inconsistent
, herein with no restrictions.
It should be noted that the relationship table between subdata and voltage signal can be preset for controller, or
It is determined for worker according to the actual use situation of panel.
Optionally, in the step S10, i.e., step is by binary data coding to be transmitted in controller at voltage signal
Later, further includes: the rule of classification is sent to memory.In the application, voltage signal is preferably together with rule of classification
It is sent to memory, decoder in memory is decoded voltage signal according to rule of classification, thus by voltage signal
It is reduced to corresponding binary data, it is to be understood that rule of classification can be preset in encoder and decoder, so just
Just do not have to rule of classification being sent to memory without controller.It is understood that between subdata and voltage signal
Relationship table can be preset in encoder and decoder, alternatively, relationship table between subdata and voltage signal and
Rule of classification together, the decoder being sent to by the encoder in controller in memory.
Optionally, the step of obtaining subdata, is being grouped to binary data to be transmitted according to the rule of classification
Later, further includes: when the number of binary data to be transmitted is unsatisfactory for the rule of classification, predeterminated position increase by two into
Number processed, so that the number of the binary data meets the rule of classification.In the application, data to be transmitted are after the grouping
The number of still remaining binary data is unsatisfactory for grouping when requiring, and encoder increases binary number in preset position, described
Predeterminated position can be divided with either the last one position of first position in subdata so that the number of binary data meets
Group rule, to complete binary data to be transmitted being divided into several subdatas.For example, rule of classification be three two into
When data processed are one group, if last be only left two binary data, a binary number 1 or 0 can be finally being supplemented at this time,
So that binary data to be transmitted can be divided into subdata.It should be noted that being solved in encoder to voltage signal
After pressure, the binary data increased newly in predeterminated position should be rejected, the signal transmitted between controller and memory is avoided to go out
Existing error.
