Detailed Description
In order to make the objects, technical solutions and advantages of the present application more clear, the present application will be further described in detail with reference to the accompanying drawings.
The embodiment of the application provides an image display method and terminal equipment, which are used for solving the problem that in the prior art, when an electronic ink screen displays an image of a third-party application which does not use an SDK, the display effect is poor. The method and the terminal device are based on the same inventive concept, and because the principles of solving the problems of the method and the terminal device are similar, the implementation of the terminal device and the method can be referred to each other, and repeated parts are not described again.
In the description of the present application, the terms "plurality" or "a plurality" mean two or more, and are used only for the purpose of distinguishing between descriptions, and are not intended to indicate or imply relative importance, nor order to indicate or imply order.
The "terminal device" related to the present invention is a device that includes a built-in display system and can implement a human-computer interaction function, and the terminal device may be a computer, a mobile phone, a tablet computer, a Point of Sales (POS), a vehicle-mounted computer, or the like.
The layer, which is composed of many pixels, is a basic unit constituting an image. One frame of image can be one image layer, and also can be formed by a plurality of image layers in an up-and-down superposition mode. The layers are films containing elements such as characters or figures, and are stacked together in sequence to form the final effect of the image.
The frame rate is usually the number of frames displaying an image in 1 second, and in the embodiment of the present invention, the frame rate is 1 second per duration of a Vertical Synchronization (Vsync) period.
According to the front Liquid Crystal Display (LCD) screen or the Organic Light-Emitting Diode (OLED) screen of the existing double-sided smart phone, the refresh rate of the front Liquid Crystal screen or the OLED screen is 60Hz or even higher than the refresh rate of the back ELINK screen of 2 Hz-8 Hz, the animation effect designed by the third-party application program according to the refresh rate of the front Liquid Crystal screen can cause great delay if the third-party application program is displayed on the back ELINK screen, and the Display effect of the animation effect of the third-party application program on the back ELINK screen is poor. Firstly, describing the flow of the front liquid crystal display displaying images according to the vsync clock signal, as shown in fig. 1, firstly executing S101 application layer image drawing according to the vsync clock signal, then executing S102 combination (composite) different image layer superposition processing, and finally executing S103 display on the front liquid crystal display, wherein the process of the combination (composite) different image layer superposition processing is as shown in fig. 2, processing each frame of image strictly depends on the vsync pulse clock signal as a synchronous signal source, keeping different modules to perform synchronous processing on the images, and executing S201 application layer drawing a first frame of image when the vsync pulse clock is X; when the vsync pulse clock is X +1, executing step S202Compse layer superposition of a first frame, and simultaneously executing step S203 to draw a second frame image by the application layer; when the vsync pulse clock is X +2, executing step S204 to display a first frame on the LCD screen, simultaneously executing step S205 to superpose the Compse layer on a second frame, and simultaneously executing step S206 to draw a third frame image by the application layer; when the vsync pulse clock is X +3, step S2047 is performed to display the second frame on the LCD screen, and step S208 is performed to superimpose the third frame on the comp layer, and so on.
For example, the frequency of the LCD screen is 60Hz, the frequency of the electronic ink screen is 4Hz, and if the 4Hz vsync clock signal of the electronic ink screen is used as the display synchronization signal source, the third-party application will draw the image according to the frequency of the 4Hz vsync clock signal. 1S animation is drawn according to the frequency of a 60Hz vsync clock signal, 60 frames of images need to be drawn, 15S animation is required when the 60 frames of images are drawn according to the frequency of a 4Hz vsync clock signal, the animation displayed on the LCD screen by 1S needs to be displayed on the electronic ink screen for 15S, the animation effect of 'slow motion' of jumping of one frame is presented, and the extremely poor use experience of a user is caused. In order to solve the above problem, an embodiment of the present invention provides an image display method, as shown in fig. 3, a third party application displays an image on an electronic ink screen, but when an application layer draws an image in step S301, a virtual vsync clock signal is set, where the virtual vsync clock signal may be generated by an S302 virtual vsync clock signal generation module, so that the application layer draws an image according to the virtual vsync clock signal, the refresh rate of the virtual vsync clock signal is the same as that of the third party application when drawing an image on an LCD screen, different picture layers of the picture in step S303 are superimposed, in a plurality of drawn images, a frame to be displayed is selected according to an actual vsync clock signal of the electronic ink screen in step S304, and in step S305, the frame is displayed on the electronic ink screen. The method can improve the experience of the user when using the electronic ink screen, but the method also has the defect that the selected final frame cannot be displayed in time, and the displayed animation effect is poor. For example, an animation with a duration of 800ms, frames are selected according to a set duration, the set duration is 250ms, the electronic ink screen displays images of 250ms, 500ms and 750ms, and then displays a final static picture at 1000ms, and the duration of the animation is 800ms, so that the display delay of the final static picture is large. When the electronic book application is used, when page turning is processed, the application displays an animation page turning effect on the LCD screen to a final display page, but a few split animation frames are displayed on the electronic ink screen, then the display of a last frame of static picture is delayed, the experience effect of a user is poor, and the lower the refreshing rate of the electronic ink screen is, the worse the experience effect of the user is. In the above case, the optimal display effect should be to display the last frame of still picture directly for the first time without displaying the middle animation.
The following describes an image display method provided by the present application with reference to the accompanying drawings, so that when the electronic ink is applied by a functional third party, a last frame of static image is directly displayed in the first time without displaying an intermediate process animation.
Referring to fig. 4, a method for displaying an image provided by the present application includes:
s401, determining the sending time of the received second frame image, wherein the sending time is the time when the application layer sends the second frame image to the next processing module after drawing the second frame image.
S402, determining the difference value between the sending time of the second frame image and the sending time of the first frame image received before.
And S403, if the difference value is judged to be larger than or equal to the set threshold value, sending the second frame image to a display buffer register.
In a possible implementation manner, after S402, the method further includes:
and if the difference is smaller than the set threshold value, discarding the second frame image.
In a possible implementation manner, after S403, the method further includes:
and acquiring the images stored in the display buffer register according to the actual vertical synchronous clock signal, and sending the images to the electronic ink screen for display according to the storage sequence.
In the embodiment of the application, an image display method is provided, when the difference value between the sending time of a second frame image and the sending time of a first frame image is larger than or equal to a set threshold value, the second frame image is sent to a display buffer register so as to be displayed on an electronic ink screen, through the image display method, images with multi-frame animation effects, which are continuously sent with the difference value smaller than the set threshold value, can be filtered, only the images with the difference value larger than or equal to the set threshold value are displayed, it is ensured that a stable static picture appears on the electronic ink screen, and the use experience of a user is improved.
The following describes an image display method provided by the present application with reference to fig. 5 specifically, when an application layer draws an image in step S501, a virtual vsync clock signal is set, where the virtual vsync clock signal may be generated by the S502 virtual vsync clock signal generation module, then step S503 performs overlay processing according to different image layers of a virtual vsync clock signal combination (composite), step S504 obtains a sending time of a received second frame image, step S505 compares whether a difference between the sending time of the second frame image and a sending time of a previously received first frame image is greater than or equal to a set threshold value, for example, 40ms is greater than 2 frames, step S506 is executed to send the last frame image to a display buffer register, otherwise, step S507 is executed to discard the second frame image, an image in the display buffer register is obtained according to an actual vsync clock signal, step 508 displays onto the electronic ink screen.
In a possible implementation manner, after S403, if an operation of the screen by the user is received, the method further includes:
receiving a touch instruction; drawing a set image triggered by the touch instruction; and overlapping the set image triggered by the touch instruction with the second frame image in the display buffer register. The overlapping processing of the setting image triggered by the touch instruction and the second frame image in the display buffer register specifically comprises the step of covering the setting image triggered by the touch instruction on the second frame image in the display buffer register.
In a possible implementation manner, after performing layer overlay processing on the setting image triggered by the touch instruction and the second frame image in the display buffer register, the method further includes:
and sending the image obtained after the superposition processing to the electronic ink screen, and refreshing a designated area on the electronic ink screen, wherein the designated area is a display area of a set image triggered by the touch instruction on the electronic ink screen.
Specifically, the image obtained after the superposition processing is sent to the electronic ink screen by a module of the application layer for the composite superposition processing.
Specifically, different touch instructions trigger different setting images, as shown in fig. 6, the setting images are respectively corresponding to a click touch instruction and a slide touch instruction, where the setting images may be displayed in a frame on the electronic ink screen and then disappear. When the set image triggered by the touch instruction is superposed with the second frame image in the display buffer register, the first line judges the original color of the click position of the user, although the electronic ink screen has only black and white colors, the electronic ink screen has a color level, the original color information of the appointed area with the click position as the center is read, and if the original color displayed in the appointed area is judged to be light tone, the clicked appointed area is displayed as dark tone; if the original color displayed in the designated area is judged to be dark, the clicked designated area is displayed to be light; the designated area is refreshed on the electronic ink screen, the electronic ink screen is not refreshed on the full screen, the display speed can be increased, more real-time display can be achieved, and the use experience of a user is improved.
For example, as shown in fig. 7, when the application layer draws an image in step S701, a virtual vsync clock signal is set, where the virtual vsync clock signal may be generated by the virtual vsync clock signal generation module in step S702, then step S703 performs overlay processing according to different image layers of the virtual vsync clock signal composite, step S704 obtains the sending time of the currently received second frame image, step S705 compares whether the difference between the sending time of the second frame image and the sending time of the previously received first frame image is greater than or equal to a set threshold value, if yes, step S706 is executed to send the second frame image to the display buffer register, if no, step 707 is executed to discard the second frame image, step S708, when the electronic ink screen receives a touch instruction, step S709 the electronic ink screen draws a set image triggered by the touch instruction, and step S710 executes overlay processing on the set image and the image obtained from the display buffer register And step S711, sending the image after the superimposition processing to the electronic ink screen for displaying, where the operation embodied on the electronic ink screen is that a designated area is refreshed.
