Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
The first embodiment of the invention relates to a method for displaying a rounded corner of a screen, which is applied to a mobile terminal such as a mobile phone, an iPad, a PC tablet computer and the like. The core of the embodiment is to configure a first screen buffer area and a second screen buffer area; acquiring a data frame of a user space of the mobile terminal and reading and writing the data frame into a first screen buffer area; after the data frame is read and written into the first screen buffer area, carrying out fillet processing on the data frame; copying the data frame subjected to the fillet processing in the first screen buffer area to a second screen buffer area; displaying the data frame subjected to the fillet processing in the second screen buffer area on a screen of the mobile terminal, so that the fillet display function of the mobile terminal is realized; moreover, as the data frame is subjected to fillet processing in the first screen buffer area, hardware in a visible area of a display screen does not need to be polished, and the manufacturing cost is reduced; the data frame after the round angle processing is performed on the data frame in the first screen buffer area, and then the data frame after the round angle processing is displayed on the screen of the mobile terminal in the second screen buffer area, and the user interfaces of all application programs do not need to be customized into round angles and then displayed, so that the method can be adapted to various applications in the market.
The specific flow in this embodiment is shown in fig. 1:
step 101: and acquiring parameters of a terminal screen, and calculating the size of a screen buffer area according to the acquired screen parameters.
Specifically, the parameters of the screen may include the resolution and the bit depth of the screen, where the resolution is the precision of the screen image and refers to how many pixels can be displayed by the display; bit depth refers to the bit depth that a computer actually needs for each pixel when recording the color of a digital image.
The display of the screen is realized by a frame buffer technology, wherein a frame buffer (Framebuffer) is an interface provided by a Linux operating system for the display device, abstracts a display buffer area, shields the bottom layer difference of image hardware, and allows an upper layer application program to directly read and write the display buffer area in a graphic mode. The user does not have to be concerned with the specific location and storage of the physical display buffer, which is done by the frame buffer driver itself, which corresponds to a device file of/dev/fb. Opening the frame buffer device file/dev/fb, and obtaining the parameters of the current display screen by using an ioctl function operation, where the ioctl function is a function of managing the input/output channels of the device in the device driver, that is, a function of controlling some characteristics of the device.
The following equation, taking resolution as an example, calculates the size of the buffer, and the formula for calculating the buffer according to resolution is: resolution x bit depth. For example: when the screen resolution is 1280 × 1024 and the bit depth is 32, the buffer size is (1280 × 1024 × 32)/8/1024, and the screen buffer size is 5120KB, where 8 is the bit-to-byte magnification and 1024 is the byte-to-kilobyte magnification.
In practical application, the memory can be calculated according to the size and bit depth of the screen, and since each screen size corresponds to a highest resolution, the size of the screen buffer can be calculated by measuring the size of the screen to obtain the corresponding highest resolution. For example, if the resolution corresponding to the 19-inch screen is 1280 × 1024, the size of the screen buffer can be obtained according to the above calculation method for calculating the size of the screen buffer with the resolution.
It can be understood by those skilled in the art that, in addition to the above method for determining the screen buffer memory according to the resolution or the size and the bit depth, the size of the screen buffer memory can be calculated by using other parameters according to the color format of the screen, which is not described in detail herein.
Step 102: and dividing a first screen buffer area and a second screen buffer area according to the size of the screen buffer area.
Specifically, the size of the memory occupied by the screen buffer is calculated according to the resolution and the bit depth of the screen, and then two screen buffers with the same size as the memory of the screen buffer are allocated according to the acquired size of the memory of the screen buffer: the first screen buffer area and the second screen buffer area, as shown in fig. 3, make the screen buffer area size calculated according to the screen parameters adapt to the screen parameters, so that the screen display of the mobile terminal can be clear.
Step 103: and acquiring a data frame of a user space of the mobile terminal and reading and writing the data frame into a first screen buffer area.
Specifically, the screen display of the mobile terminal is displayed in a data frame mode, the data frame of the user space of the mobile terminal is obtained and read and written into the first screen buffer area, and namely, the picture of the display screen of the mobile terminal is mapped to the first screen buffer area. The data frame in the present embodiment is described by taking one frame as an example, and in practical application, the processing method for other data frames is the same as the above processing method.
Step 104: and performing fillet processing on the data frame.
Specifically, the data corresponding to the four corners of the display screen in the data frame is set to black. Example as shown in fig. 2, a display screen 202 is provided in a mobile terminal 201, and the display screen 202 includes a screen black border 203 and a screen visible area 204. An arc with a radius of 1.88 mm is made at the four corners of the visible area 204 of the screen. The color values are written in the areas, corresponding to the display points, of the display buffer area, the corresponding colors can be automatically displayed on the screen, therefore, the data, corresponding to the areas outside the four-corner arcs of the screen visual area 204 in the data frame, are set to be black, namely, the round angle processing of the data frame is realized, and the screen visual area 204 is displayed as a round angle. And because the current mobile terminal display screen frame is most for the black, consequently set up the data in display screen four corners into the black for the data in display screen four corners and mobile terminal display screen frame fuse together, have further promoted user experience.
Preferably, the radian of the four corners of the screen black border 203 can also be used as the radian of the four corners of the screen visible area 204, for example, when the radian of the four corners of the screen black border 203 is 1.88 mm in radius, then the radian of the four corners of the screen visible area 204 can be set to 1.88 mm in radius. Here, the color is not limited to the radian of the four corners of the screen visible region 204 and the color when the region outside the arc of the four corners of the screen visible region 204 is set.
Step 105: and copying the data frame subjected to the fillet processing to a second screen buffer area.
Specifically, after the data frame is subjected to the rounding processing in the first screen buffer area, the rounded data frame is copied to the second screen buffer area, and the user interfaces of all application programs do not need to be customized into a rounded corner, so that all applications on the market can be adapted.
Step 106: and displaying the data frame in the second screen buffer area to the screen of the mobile terminal.
Specifically, the data frame processed by the fillet in the second screen buffer area is displayed on the terminal screen, the displayed picture is distributed in the screen visible area 204, and the area outside the four-corner arc of the screen visible area 204 is consistent with the border in color, so that the fillet display of the screen is realized.
