Background
A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. Wearable equipment is not only a hardware equipment, realizes powerful function through software support and data interaction, high in the clouds interaction more, and wearable equipment will bring very big transition to our life, perception, if: intelligent bracelet.
Generally, a TFT screen provided in a wearable device refers to a 16-bit true color screen. At present, the display effect of the smart band equipped with a TFT screen is limited, the User Interface (UI) display is similar to the effect of the traditional 'function machine' era of the mobile phone, and a black background is added with a colored icon. And moreover, transition animation is not generated when the interface is switched, the screen effect is single, and the display is monotonous.
Accordingly, the prior art is deficient and needs improvement.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a TFT screen display method of wearable equipment.
The technical scheme of the invention is as follows: the invention provides a display method of a TFT screen of wearable equipment, which comprises the steps of storing display contents into an RAM (random access memory) and displaying the display contents on the TFT screen, wherein the display contents comprise wallpaper data and icon data, and storing the wallpaper data in the display contents into a memory; when the animation is started, the display content in the RAM is shifted, and the display content is updated: separating the icon data from the wallpaper data in the display content, removing the wallpaper data, calling the originally stored wallpaper data from the memory, combining the wallpaper data with the icon data in the display content after the deviation, filling the data of the corresponding part of the next interface to the corresponding deviation position in the RAM according to the deviation amount, thereby obtaining new display content, and storing the new display content to the corresponding position of the RAM.
And (4) shifting the icon, wherein an overlapping area is formed between the icon and the wallpaper in the process of moving upwards, and the color of each pixel point in the overlapping area is calculated according to the required transparency.
The color of each pixel point in the overlapping region comprises red, green and blue, wherein:
red lightness ═ (R1X + R2 (100-X))/100;
the lightness of green (G1X + G2 (100-X))/100;
the brightness of blue (B1X + B2 (100-X))/100;
x is required transparency and is set in advance; r1, G1, B1 are the original brightness values of red, green, blue of the pixel points corresponding to the icon, respectively, and R2, G2, B2 are the original brightness values of red, green, blue of the pixel points corresponding to the wallpaper, respectively.
Before the display content is stored in the RAM, the RAM with the same size as the screen GRAM is applied in the memory according to the screen size of the TFT screen.
The TFT screen is a 16-bit true color screen.
The memory is a FLASH memory.
By adopting the scheme, the invention provides the TFT screen display method of the wearable device, new display content is synthesized again in the display process, and the effect that the wallpaper and the icon have animation effect simultaneously on the TFT screen frame by frame is realized; the icon has a transparent effect, can be combined with the background more attractively, can generate a UI effect similar to that of the existing smart phone, and improves user experience.
Drawings
FIG. 1 is a scrolling flowchart of a TFT screen display method of a wearable device according to the present invention.
Detailed Description
The invention is described in detail below with reference to the figures and the specific embodiments.
The invention provides a display method of a TFT screen of wearable equipment. Firstly, in order to ensure smooth screen refreshing animation, a RAM with the same size as the GRAM of the screen is applied in a memory according to the screen size of the TFT screen. Such as: the size of the RAM is:
[SCREEN_WIDTH_SIZE*SCREEN_HIGH_SIZE*2]
storing display contents into a RAM (random access memory) and displaying the display contents on a TFT (thin film transistor) screen, wherein the display contents comprise wallpaper data and icon data, and storing the wallpaper data in the display contents into a memory; when the animation is started, the display content in the RAM is shifted, and the display content is updated: separating icon data from wallpaper data in the display content, removing the wallpaper data, calling the originally stored wallpaper data from a memory, combining the wallpaper data with the icon data in the display content after the wallpaper data is offset, filling data of a corresponding part of a next interface (such as a UI of the next interface) to a corresponding offset position in the RAM according to the offset, so as to obtain new display content, storing the new display content to the corresponding position of the RAM, and writing the new display content into a screen GRAM through a hardware interface to finish the display.
In order to solve the transparency problem of the overlapped part of the icon and the wallpaper, the color of the pixel of the overlapped part is reset: and (4) shifting the icon, wherein an overlapping area is formed between the icon and the wallpaper in the process of moving upwards, and the color of each pixel point in the overlapping area is calculated according to the required transparency.
The color of each pixel point in the overlapping region comprises red, green and blue, wherein:
red lightness ═ (R1X + R2 (100-X))/100;
the lightness of green (G1X + G2 (100-X))/100;
the brightness of blue (B1X + B2 (100-X))/100;
x is required transparency and is set according to actual needs; r1, G1 and B1 are original brightness values of red, green and blue of pixel points corresponding to the icon respectively, and R2, G2 and B2 are original brightness values of red, green and blue of pixel points corresponding to the wallpaper respectively, and can be obtained by directly reading parameter values of the icon and the wallpaper. .
The TFT screen is a 16-bit true color screen. The memory is a FLASH memory.
As shown in fig. 1, the wallpaper with the spiral threads, the previous icon (interface) is a, the next icon (interface) is B, and a transition animation effect is achieved when switching from icon a to icon B in the sliding process.
In summary, the invention provides a wearable device TFT screen display method, which re-synthesizes new display content during the display process, so that the wallpaper and icons can be animated on the TFT screen frame by frame; the icon has a transparent effect, can be combined with the background more attractively, can generate a UI effect similar to that of the existing smart phone, and improves user experience.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
