Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In accordance with an embodiment of the present application, there is provided an embodiment of a method for transmitting display data, it should be noted that the steps shown in the flowchart of the figure may be executed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that shown.
Fig. 3 is a flowchart of a transmission method of display data according to an embodiment of the present application, and as shown in fig. 3, the method includes the following steps:
step S302, dividing target data in data to be displayed into multi-part data, wherein the data to be displayed is displayed in a display according to lines, and the target data is any line of data except the first line of data in the data to be displayed;
step S304, each part of data in the target data is compared with each corresponding part of data in the previous row of data to be displayed of the target data, wherein the previous row of data to be displayed is stored in a driving chip, and the driving chip is used for sending the data to be displayed to a display for displaying;
step S306, determining the data to be displayed sent to the driving chip from the data to be displayed according to the comparison result.
Through the steps, the purposes of improving the utilization rate of data transmission and reducing the utilization rates of the output circuit of the TCON chip and the receiving circuit of the driving chip are achieved by improving and optimizing the data transmission mode between the TCON and the driving chip, and therefore the technical effect of reducing power consumption on the basis of keeping the display effect is achieved.
According to an alternative embodiment of the present application, the step S302 is performed by dividing the target data into multi-part data according to the number of driver chips and the data structure of the target data, wherein the number of parts of the divided data is the same as the number of driver chips.
Before outputting the Nth row of data, the TCON chip divides the Nth row of data into x parts (x is the same as the number of the driving chips) according to the number of the driving chips and the data structure.
According to an alternative embodiment of the present application, before dividing the target data in the data to be displayed into multi-part data, the first row of data needs to be divided into the multi-part data according to the number of the driving chips and the data structure of the first row of data; and respectively sending each part of divided data in the first row of data to a driving chip for storage.
In this step, the first row of data in the data to be displayed is divided into x parts (x is the same as the number of the driving chips) according to the number of the driving chips and the data structure. And the divided data are respectively sent to the driving chips.
In some optional embodiments of the present application, step S306 is implemented by: if each part of data in the target data is the same as each corresponding part of data in the previous row of data to be displayed of the target data, refusing to send the data to the driving chip; and if different data exist in each part of data in the target data and each part of data corresponding to the data to be displayed in the previous line of the target data, sending the data which are different from the data to be displayed in the previous line of the target data in the target data to the driving chip.
According to an optional embodiment of the present application, if each part of data in the target data is the same as each corresponding part of data in the previous row of data to be displayed of the target data, sending a holding signal and a control signal to the driving chip, wherein the driving chip keeps the previous row of data to be displayed stored in the driving chip unchanged after receiving the holding signal; and after receiving the control signal, sending the previous row of data to be displayed to the display for displaying.
As mentioned above, the TCON chip divides the nth data into x parts (x is the same as the number of the driving chips) according to the number of the driving chips and the data structure before outputting the nth data. After the division is completed, each part of data is compared with each part of data corresponding to the (N-1) th line respectively. If each part of the data in two rows is the same, the TCON chip does not output data. The Hold signal (Hold signal) is output to the driving chip, and then the Gate Timing signal is output. The driving chip keeps the data of the previous line, and after receiving the Gate Timing signal, the data is displayed on the LCD.
According to another optional embodiment of the present application, if each part of data in the target data and each corresponding part of data in the previous row of data to be displayed of the target data have different data, after synchronizing the different data to the control signal, sending the different data to the driving chip through the control signal, wherein the driving chip replaces the corresponding data in the previous row of data to be displayed with the received different data, and sends the same data in the target data in the previous row of data to be displayed and the received different data to the display together for displaying.
If the Data of each part in the target Data is different from the Data to be displayed in the previous line of the target Data in the x-th part, the P2P interface power on of the TCON chip pulls down the Data Hold corresponding to the driving chip and outputs the x-th part of the Data to the driving chip. In the data identical part, the P2P interface of the TCON chip holds power down with no data output. The Data High is held High, the driver chip does not accept the receipt, and the circuitry of the receive part holds power down. The driving chip receives the x-th part with different Nth row of data, stores the x-th part and displays the x-th part on the LCD.
Fig. 4 is a schematic diagram of a transmission method of display data according to an embodiment of the present application, where each row of data is divided into 4 portions, and data of the second row and the third row are compared, and only data of the third portion is different, as shown in fig. 4. In this case, the TCON chip only needs the power on corresponding to the P2P interface of the third driver chip, and pulls down the Data Hold corresponding to the third chip. Thus, the rest of the P2P interface of the TCON chip and the receiving circuit of the other driver chip are all in the power down state.
By adopting the Point-to-Point (Point-to-Point) data transmission mode between the TCON chip and the drive chip, when each row of data is completely different from the previous row of data, the working mode is the same as that of the traditional P2P protocol; when only one part of continuous line data is different, the output circuit of the TCON chip and the receiving circuit of the driving chip can reduce the utilization rate and enter a power down state, thereby achieving the technical effect of reducing the power consumption.
