Description

Control method, system, smart watch and medium for smart watch screen display

technical field

The present application relates to the technical field of smart watches, in particular to a method, system, smart watch and medium for controlling screen display of smart watches.

Background technique

In the field of smart wearables, smart watches, as one of the most popular products, are committed to bringing users a one-stop smart monitoring and information acquisition experience. Compared with smart bracelets, the most obvious distinguishing feature of smart watches is that they usually have a larger display screen. As the main medium for users to obtain information and operate, the display screen is high-resolution, high-contrast and high-color in terms of display effects. Vibrance development. At the same time, in order to adapt to the user's habit of wearing the watch, such as wearing on the left hand and wearing on the right hand, the screen display direction of the watch needs to be flexibly adjusted. Moreover, when the hardware orientation of the watch screen is inconsistent with the actual user orientation, the screen display orientation also needs to be adjusted.

At present, the existing method for adjusting the screen display of a smart watch is generally to configure a screen driver chip that can adjust the scan order, so as to realize the conversion of the cache pixel order of the drive display and the screen scan direction. For example, when rotated by 180 degrees, the screen driver chip scans the corresponding buffer pixels in sequence from the last pixel in the normal sequence, and reads and displays in sequence forward. When rotated 90 degrees (including clockwise and counterclockwise), the screen driver chip will perform scanning in the order of swapping the rows and columns of the buffer pixels.

However, the above-mentioned implementation scheme has high requirements on the hardware performance of the screen driver chip, and the cost is relatively expensive; and in practical applications, it is found that due to the communication speed and screen refresh rate between the main control chip of the smart watch and the screen driver chip, there is often a certain level of refresh rate. Therefore, the data of each frame cannot be transmitted within the time interval specified by the screen driver chip. When the data transmission has not been completed, the screen driver chip starts to scan the screen. At this time, one frame of the screen will display two frames of display buffered data mixed. The visual experience brought to the user is that the display screen is torn and the experience poor.

In view of the above, the technical problems existing in the related art need to be solved urgently.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, but should not be construed as a limitation on the present application. The numbers of the steps in the following embodiments are only set for the convenience of description, and the sequence between the steps is not limited in any way, and the execution sequence of each step in the embodiments can be adapted according to the understanding of those skilled in the art Sexual adjustment.

At present, the existing smart watches generally use the hardware itself to realize the angle rotation of the display screen by configuring the register of the screen driver chip. There are several problems with this method: first, some screen driver chips do not support special angles (such as 90 degrees). ) rotation, or even does not support any rotation; secondly, the screen driver chip that supports rotation can only scan from a fixed angle during screen scanning, such as reverse scanning, and although the display angle can be switched, the display effect It will bring a greater impact on the screen, and it is prone to the problem of screen splitting.

In view of this, an embodiment of the present application provides a method for controlling screen display of a smart watch. The method in the embodiment of the present application can be applied to a smart watch. Specifically, it can be stored in the memory of the smart watch in the form of program codes. , which is implemented by processor execution. The smart watch in the embodiments of the present application refers to any watch with interactive and display functions that is worn by the user. The smart watch includes a display cache chip, which is used to store and process pixel data of the display screen; it also includes a screen driver chip, which is used to scan the pixel data stored in the display cache chip and display the corresponding image on the screen. 1, the method in the present application mainly includes the following steps:

Step 110, obtaining the rotation degree of the smart watch;

In the embodiments of the present application, when determining the rotation degree of the smart watch, in some embodiments, the rotation degree of the watch may be determined according to a device such as a gyroscope installed in the smart watch; The degree may be related to the position where it is placed. For example, when it is placed on the charging stand, the placement angle of the smart watch and the wearing angle are a certain degree. At this time, in order to facilitate the user to browse, the screen display needs to be rotated. When the watch detects the charging state, it rotates the screen by a certain degree; in some embodiments, it can also be determined according to the user's wearing setting information, such as whether he is used to wearing the left hand or the right hand, by obtaining the user's wearing setting information. The degree of rotation of the corresponding smart watch to provide users with a better screen browsing experience.

Step 120: Obtain from the display cache chip the first pixel matrix of the screen displayed before the smart watch rotates;

In the embodiment of the present application, for a smart watch, the user interface interaction is generally processed through the GUI, that is, the user's interaction instructions are obtained and processed, the coordinate information of each control and the screen area that needs to be refreshed are calculated, and the corresponding pixel data is drawn. . These pixel data are then sent to the display cache chip to be cached, and then scanned by the screen driver chip and displayed on the screen, thereby completing the presentation of the picture. Therefore, for each frame of picture, its pixel data is stored in the display buffer chip. In the embodiment of the present application, each pixel data of the display picture stored in the display buffer chip is recorded as the first pixel matrix. When the picture needs to be rotated, the pixels of the last frame before the rotation are stored in the display cache chip, which is equivalent to the picture at the normal angle before the rotation; according to the first pixel matrix corresponding to the frame, the smart watch screen after the rotation can be determined. The pixel data that needs to be displayed at each location.

Step 130: Rearrange each pixel in the first pixel matrix in the display cache chip according to the rotation degree to obtain a second pixel matrix;

In the embodiment of the present application, according to the rotation degree of the smart watch, each pixel in the first pixel matrix obtained from the display cache chip can be rearranged, so as to achieve the effect that the rearranged pixels are the rotation degree corresponding to the rotation of the original image, In the embodiment of the present application, the rearranged pixel data is recorded as the second pixel matrix.

Specifically, taking a rotation of 90 degrees as an example, a more direct approach is to set two display cache chips, and the storage formats of the two chips are unified. For example, currently one of the display cache chips stores the first pixel matrix, then data can be read row by row from the display cache chip and copied to each column of the memory space of the other display cache chip. In this way, in the display cache chip that stores the first pixel matrix, after the pixel data of each row is copied, the memory space of the other display cache chip stores the pixel data rotated by 90 degrees, that is, the second pixel matrix.

Step 140, sending the second pixel matrix to the screen driver chip through a hardware protocol;

Step 150: Scan the second pixel matrix according to the original scanning order by the screen driver chip, and display the rotated picture on the smart watch.

In this step, the pixel data in the second pixel matrix can be directly used as the display buffer of the current frame, so the second pixel matrix in the display buffer chip can be sent to the screen driver chip through the hardware protocol. It is the pixel data of the processed and rotated picture, so the screen driving chip can scan the second pixel matrix according to the original scanning order, and complete the picture display of the screen. It can be understood that the method in the embodiment of the present application does not require the screen driver chip to adjust the order of scanning pixel data, which can reduce the hardware cost of the screen driver chip; It is the second pixel matrix, including the pixel data of a complete picture, and there will be no picture tearing caused by inconsistent refresh frequency, which can provide a more stable visual experience.

Preferably, the embodiment of the present application also includes the following steps:

obtain the screen resolution of the smart watch;

According to the rotation degree and the screen resolution, transposing each pixel in the first pixel matrix in the display cache chip to obtain a third pixel matrix;

sending the third pixel matrix to the screen driver chip through a hardware protocol;

The screen driving chip scans the third pixel matrix according to the original scanning sequence, and displays the rotated picture on the smart watch.

Although the method in the foregoing embodiment is more efficient in terms of time efficiency when processing screen display, the hardware cost is also relatively high, because two frames of pixel data of a complete screen are required, and generally two display cache chips are used. The size of the smart watch is relatively small, and the hardware structure is required to be compact; and the screen is small and the resolution is high, so the memory requirements for the main control microcontroller of the smart watch are very high.

Therefore, in the case where the chip memory of the smart watch is tight, in order to reduce the consumption of the memory, an in-situ rotation algorithm may also be used to process the first pixel matrix in the embodiment of the present application. Specifically, the algorithm is directly completed in the display buffer of a frame of pictures, and there is no need to open up a new memory space for a complete picture frame. In actual operation, the corresponding relationship between the pixels before and after rotation can be established through matrix operation, and the pixels in the display cache chip can be exchanged in situ according to the corresponding relationship, so as to obtain the rotated pixel data, and after the exchange operation of all pixels is completed , the pixel data after rotation is stored in the display cache chip, and the data is recorded as the third pixel matrix. At this time, the screen driving chip data can be directly transmitted. The steps of the subsequent scan and display are similar to the aforementioned steps 140 and 150, and are not repeated here.
