Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, in the following description and the accompanying drawings, detailed descriptions of well-known functions or configurations that may obscure the subject matter of the present invention will be omitted. In addition, it should be noted that like reference numerals refer to like elements throughout.

The terms or words used in the specification and claims described below should not be construed as being limited to ordinary or dictionary meanings, and the inventors are appropriate as concepts of terms for explaining their own invention in the best way. It should be interpreted as meanings and concepts in accordance with the technical spirit of the present invention based on the principle that it can be defined. Therefore, the embodiments described in the present specification and the configuration shown in the drawings are only the most preferred embodiments of the present invention, and do not represent all of the technical ideas of the present invention, and various alternatives may be substituted at the time of the present application. It should be understood that there may be equivalents and variations.

The present invention scrolls and displays a page according to a user's touch input. This method will be described. 1 is a diagram illustrating a page scrolling method according to an exemplary embodiment of the present invention.

Referring to FIG. 1, reference numeral 10 denotes a page. Here, the page is a file unit displaying any one content. For example, the page 10 may be a list file such as a menu, an executable file, and data, or may be a text file, a picture file, a web page, or the like, and includes all kinds of unit files that can be displayed on the screen.

When the size of the page 10 is large, the terminal cannot display all one page 10 on one screen due to the size constraints of the display device provided by the terminal, and displays only a part 11. do. Accordingly, in order for the user to see the invisible portions 13 and 15 of the page 10, the user must operate the terminal to display the invisible portions 13 and 15 of the page on the screen. At this time, a useful function is scrolling.

There are a variety of operation methods for executing a specific function on a specific device, but the embodiment of the present invention takes a touch input as a preferred example. Touch input refers to the act of performing input by touching a device that senses the touch input using an input tool. Here, the input tool may illustrate a part of the body such as a fingertip or a stylus. In addition, the touch input display unit 110 is used as a device for detecting a touch input, and the touch input display unit 110 detects a touch input and simultaneously displays a screen, and may be a so-called “touch screen”. This will be described in more detail below.

There may be various operations for the touch input for scrolling the page 10, but embodiments of the present invention use drag and release operations. That is, when the touch input display unit 110 continuously detects drag and release operations, the page 10 is scrolled and displayed on the screen. Here, the drag means that the input tool moves by the predetermined length after the contact with the touch input display unit 110 maintains the contact. The release means that the input tool maintains contact with the touch input display 110 and then releases contact at one point.

In FIG. 1, it is assumed that a user performs a drag and release of the touch input display unit 110 using an input tool (fingertip). Reference numeral 17 is an area in which dragging is performed, and reference numeral 19 is an area in which release is performed. When the touch input display 110 detects drag and release continuously, the screen is automatically scrolled by a predetermined length after detecting the release. In this case, the scrolling is performed in the dragged direction 21, and the invisible portion 15 of the page is scrolled and displayed. In addition, the entire length of the scroll automatically is referred to as the total scroll length (H). The overall scroll length H is adjusted according to the touch input. That is, the entire scroll length H may be adjusted in consideration of at least one of a pressure detected during dragging or releasing, a speed of dragging, and a length of the dragged region. For example, as the pressure detected at the time of dragging or releasing, the speed of dragging, or the length of the dragged area is longer, the entire scroll length H can be adjusted in proportion to this.

In the above-described embodiment of the present invention, the scroll direction is assumed to be described as one direction of the page 10. However, the present invention is not limited thereto, and it is natural that the user may perform the scroll in any direction according to the touch input.

Scrolling of the page 10 according to an embodiment of the present invention is divided into a plurality of frames, the page 10 is expressed using an animation effect that displays a plurality of divided frames in succession. Here, the frame display period f and the unit scroll length h are used as parameters for scrolling. According to an embodiment of the present invention, by performing scrolling by normalizing the frame display period f and the unit scroll length h, the size of data to be used can be predicted in advance, and the memory can be used in scale according to the prediction. In addition, the response speed can be improved by loading and using only the minimum required capacity into the memory. These parameters will be described.

2A and 2B are diagrams for describing parameters used for scrolling according to an embodiment of the present invention.

Referring to FIGS. 2A and 2B, the scrolled page 10 is not actually displayed while the page 10 moves, but displays the scrolling of one page 10 using a plurality of frames 30. do. That is, the screen on which the page 10 is scrolled is represented through an animation effect in which a plurality of frames 30 are displayed at regular intervals. 2A and 2B illustrate a number of frames 30 displayed sequentially over time. For example, the first to fifth frames 31 to 35 are displayed at times t1, t2, t3, t4 and t5, respectively, and the intervals at which each of the first to fifth frames 31 to 35 are displayed are constant. That is, each of the frames 30 is displayed at every frame display period f. In this way, the present invention normalizes the frame display period f in which each frame 30 divided from the page is displayed.

When the performance of the terminal is good, the frame 30 may be displayed in a shorter frame display period f. On the other hand, if the performance of the terminal is not good, the speed of displaying the frame 30 is low, it may not be possible to display all one frame 30 in one frame display period (f). As described above, the poor performance of the terminal occupies the largest portion of the performance of the device in charge of image processing, but other devices such as input / output (I / O) devices may become a problem. In addition, aging of the device may degrade its performance. Therefore, according to the embodiment of the present invention, the parameter is normalized in consideration of the comprehensive performance of the terminal. In addition, the parameters are normalized in consideration of the user's preference as well as the performance of the apparatus. To this end, the test set the overall performance of the terminal and the frame display period (f) to satisfy the user, but reflects the time that the terminal can display one frame, longer than or equal to that time The frame display period f is set.

3 is a view for explaining a parameter used for scrolling according to an embodiment of the present invention.

Referring to FIG. 3, the scrolled pages 10 are sequentially displayed with each of the plurality of frames 30 in accordance with the frame display period f as described above. At this time, each frame 30 is displayed by scrolling a predetermined length with respect to the frame 30 immediately displayed. As such, when the page 10 is scrolled and displayed on the screen, the length scrolled by the frame 32 currently displayed in the previous frame 31 is called unit scroll length h.

According to an embodiment of the present invention, this unit scroll length h is normalized using a normalized frame display period f. That is, if the frame display period f described above is determined, the unit scroll length h may be calculated according to the determined frame display period f. A method of calculating the unit scroll length h will be described. The total length the page scrolls automatically is called full scroll length (H). First, find the total scroll length (H) for the test, and then determine the total scroll time (T) taken to scroll by that full scroll length (H). Obtain When the total scroll time T is divided by the frame display period f, the number of frames n that can be displayed during the entire scroll time T can be calculated. The unit scroll length (h) is a value obtained by dividing the total scroll length (H) by the number of frames (n) that can be displayed during the entire scroll time (T).

For example, it is assumed that the total scroll length H is 100, and the total scroll time T is 100. In this case, if the frame display period f is 10, and the time T taken to scroll is divided by the frame display period f, the number of frames n that can be displayed during the entire scroll time T is ten. Since the scrolling of the page 10 should be expressed in 10 frames, the unit scroll length (h) is the number of frames (n) that can display the entire scroll length (H) for the entire scroll time (T). Divide by 10. Accordingly, each frame scrolls and displays the page by unit scroll length (h) 10.

According to an embodiment of the present invention, a page is scrolled and displayed on the screen by using the frame display period f and the unit scroll length h normalized by the method described above. That is, according to an embodiment of the present invention, a plurality of frames are sequentially displayed according to the frame display period f, and each of the plurality of frames is part of a page, and is scrolled by a unit scroll length h from a previous frame. .

On the other hand, as described above, by changing the normalized unit scroll length (h) it is possible to adjust the speed of the scroll. 4 is a graph for explaining a method of adjusting a scroll speed according to an embodiment of the present invention.

Referring to FIG. 4, according to an exemplary embodiment of the present invention, the scroll speed may be adjusted to remove the flatness when the scrolled page scrolls at the same speed and to provide an interesting user experience.

4 illustrates a scroll speed control line 80 according to an embodiment of the present invention. The horizontal axis represents the time t scrolled, and the scroll time t increases and decreases according to the touch input. The vertical axis represents the unit scroll length h, and the unit scroll length h is proportional to the scroll speed. That is, since the frame display period f is normalized and constant (constant, constant), as the unit scroll length h increases, the user increases the speed of scrolling due to the animation effect.

According to the scroll speed control line 80, the scrolled frame is displayed according to the corresponding unit scroll length for each frame display period f at the horizontal scrolling time t. For example, at time t1, a frame is displayed with the unit scroll length as h1.

Depending on the animation effect, the speed at which the screen scrolls is proportional to the unit scroll length. Accordingly, the unit scroll length gradually increases in the section A 41, and the unit scroll length gradually decreases in the section B 43. This may have the effect of speeding up and slowing down scrolling and then ending. As such, the scroll speed may be adjusted by increasing or decreasing the scroll speed from the beginning of the scroll to the end of the scroll. In order to increase the scrolling speed according to the above-described embodiment of the present invention, the unit scroll length may be reduced in a certain section in order to increase the above-described unit scroll length in a predetermined section and to slow down the scrolling speed.

As described above, according to the embodiment of the present invention, the frame display period f and the unit scroll length h, which are parameters used to scroll the page, are normalized, and scrolling is performed using this normalized parameter. This has the following advantages. In order to display a smooth screen when a general page is scrolled, the entire page must be loaded in memory and scrolled. However, when scrolling is performed according to a normalized parameter as in the embodiment of the present invention, only a minimum frame may be loaded into the memory without loading the entire page in advance. In addition, since only a part of the page may be loaded, the response speed according to the user's input may be improved.

Next, the screen display apparatus of the terminal using the above-mentioned parameters will be described. 5 is a diagram illustrating a screen display device of a terminal according to an exemplary embodiment of the present invention.

The screen display device of the terminal according to the embodiment of the present invention includes a touch input display unit 110, a control unit 120 and a storage unit 130.

The touch input display 110 may be divided into a touch sensing device 111 and a display device 113. In this case, when the touch sensing device 111 and the display device 113 are combined into one device, the touch input display 110 may be a touch screen. In addition, the touch sensing device 111 and the display device 113 may be formed as separate devices.

The touch sensing device 111 detects an overall touch input through an input tool and provides the detected touch input to the controller 120. Here, the input tool of the touch input may use a part of the body such as a fingertip or a stylus. These touch inputs provide an intuitive user experience (UX, User eXperience) to the user.

The touch sensing device 111 may determine whether the input tool is in contact or is released, the position at which the input tool is in contact, the time when the input tool is in contact, the number of times the input tool is in contact, and the time that the input tool is in contact with. The controller detects at least one of a trajectory and a moving speed of the input tool while the input tool is in contact, and a strength of the contact of the input tool. Based on this, the touch sensing device 111 may detect the continuous operation of dragging and releasing. That is, the touch sensing device 111 is dragged to move by a predetermined length in a direction after the input tool contacts the touch sensing device 111 and maintains the contact, and any one of the touch sensing devices 111 is performed. If the release operation in which the contact is released at the point occurs continuously, it informs the control unit 120. In addition, the touch sensing apparatus 111 informs the controller 120 of at least one of the pressure, the speed of the drag, and the length of the dragged region, which are detected when the above-described drag or release is performed.

The display device 113 is a device that displays screen data. The display device 113 may receive a part of a page, that is, a frame, from the controller 120 and display the screen. In addition, the display device 113 visually provides various information such as a menu of the terminal, user data input by the user, configuration configuration information, and the like. In particular, the frame according to the embodiment of the present invention has a display size of the display device 113, and the display device 113 displays a screen in units of frames.

In particular, the display device 113 displays the scrolled page output from the controller 120 on the screen. In this case, the scrolled page may be input to the display device 113 for each frame.

The controller 120 detects a touch input through the touch sensing device 111. That is, the controller 120 receives a touch input from the touch sensing device 111. Here, the touch input includes a continuous operation of dragging and releasing. In addition, the controller 120 receives at least one of the pressure, the speed of the drag, and the length of the dragged region, which are detected by the touch sensing device 111 when dragging or releasing.

When the controller 120 senses the touch input, the controller 120 scrolls the page according to the calculated parameter and displays the screen on the display device 113. Here, the parameter may include a frame display period f and a unit scroll length h, and the controller 120 may calculate the frame display period f and the unit scroll length h through a user's test input. . That is, the controller 120 scrolls the page using the frame display period f and the unit scroll length h to display the screen on the display device 113.

At this time, the controller 120 adjusts the entire scroll length H through which the page 10 is scrolled according to the touch input. That is, the controller 120 adjusts the overall scroll length H through which the page is scrolled in consideration of at least one of a pressure detected at the time of dragging or releasing, the speed of dragging, and the length of the dragged region. For example, as the pressure detected at the time of dragging or releasing, the speed of dragging, or the length of the dragged area is longer, the entire scroll length H that is scrolled can be adjusted longer.

In addition, as the scrolling is performed, the controller 120 may gradually increase the unit scroll length to gradually increase the scroll speed, or gradually decrease the unit scroll length to gradually slow down the scroll speed.

If the controller 120 detects a touch input while scrolling the page 10, the controller 120 may terminate the scroll. In addition, when the entire scroll length H is determined according to the touch input, the controller 120 scrolls by the entire scroll length H and ends.

The storage unit 130 is basically a device for storing data, and includes a main memory device and an auxiliary memory device. The storage unit 130 stores various data generated according to the execution of the function of the terminal. In particular, the storage unit 130 stores the calculated value when the frame display period and the unit scroll length according to the embodiment of the present invention are calculated. In addition, the storage unit 130 stores the scroll speed control line 80 according to an embodiment of the present invention. The storage unit 130 may store a page to be displayed and each frame thereof.

Next, a method for calculating a parameter according to an embodiment of the present invention will be described. 6 is a screen example illustrating a method of normalizing a parameter according to an embodiment of the present invention, and FIG. 7 is a flowchart illustrating a method of normalizing a parameter according to an embodiment of the present invention.

6 and 7, it is assumed that a user requests a corresponding function for adjusting a parameter for scrolling. Accordingly, the control unit 120 displays the frame display period control bar 60 on the screen in step S701. An example of a screen displaying the frame display period control bar 60 is illustrated in FIG. 6. The user may adjust the frame display period through the frame display period control bar 60, and adjust the frame display period as the user touches the button 61 and drags left and right. The frame display period adjusting bar 60 limits the upper limit and the lower limit of the frame display period to the user, and reference numerals 63 and 65 denote the case where the frame display period is the shortest and the frame display period is the longest, respectively. Indicates. At this time, when the frame display period is the shortest (63) is the minimum time it takes for the terminal to display one frame, which is reflected based on the performance of the terminal. That is, it means a time at which the terminal can display one frame. In the case where the frame display period is the longest (65), the extent to which the screen is not broken is considered in consideration of animation effects. This can be derived from repeated experiments. In this way, the frame display period adjustment bar 60 represents the upper and lower limits of the frame display period that can be set by the user, and allows the user to adjust the range within the upper and lower limits.

When the user completes the frame display period adjustment by inputting a desired frame display period through the frame display period control bar 60, the controller 120 detects this in step S703 and displays a test page in step S705.

The test page is a page for confirming the actual scrolling operation and is at least larger than the screen size of the display device. In addition, in this page, the scrolling is performed for any touch input by a predetermined length, that is, the entire scroll length (H). That is, the entire scroll length H is set to a preset reference value. Here, the reference value is a predetermined value for setting the parameter. If the total scroll length H set as the reference value is too long, the amount of computation required to calculate the parameter increases. In addition, if the total scroll length H is too short, the user may not clearly know whether the scrolled page is smoothly rendered, and the reliability of the normalized parameter is lowered. Therefore, the total scroll length (H) of the test page is desirable to find and set a suitable value through several experiments.

In the state in which the test page is displayed, if there is a user's touch input, the controller 120 detects this in step S707, scrolls the page by the total scroll length H preset in step S711, displays the screen, and stops. In the scrolling of the page, the control unit 120 stores the scroll start time and the stop time of the test page in step S709 and the step S713 after the scrolling of the page before starting the scrolling of the page, respectively.

Meanwhile, the user may check whether the scroll is displayed smoothly through the screen on which the scrolled page is displayed. The display of such a screen varies depending on the user's preference. Therefore, the user can set again until satisfied. If satisfied, the user may enter to confirm that this setting will be maintained, or to enter a reset that is desired to be reset. The control unit 120 detects the above-described user input in step S715, and proceeds to step S701 or S717.

At this time, if there is a reset input, the controller 120 proceeds to step S701 and repeats steps S701 to S713. On the other hand, if there is an input to confirm, the control unit 120 stores the frame display period as set by the user in step S703 in step S717.

Then, the control unit 120 displays the frame display period (f) previously set in step S719 (step S717), the scroll start time and end time previously stored (steps S709 and S713), and the preset total scroll length (H). To set the unit scroll length. That is, in step S719, the controller 120 calculates the total scroll time T taken to scroll by the entire scroll length H, using the start time and the end time of the previously stored scrolls (steps S709 and S713). The unit scroll length h is set using the previously set frame display period f and the previously calculated total scroll time T. At this time, the time T taken to scroll is divided by the frame display period f to obtain the number n of frames that can be displayed during the entire scroll time T. FIG. Then, the unit scroll length (h) is obtained by dividing the entire scroll length (H) by the number of frames (n) that can be displayed during the entire scroll time (T).

Next, a scroll speed adjustment setting method according to an embodiment of the present invention will be described. 8A and 8B are screen examples for setting scroll speed adjustment according to an embodiment of the present invention, and FIG. 9 is a flowchart illustrating scroll speed adjustment according to an embodiment of the present invention.

4, 8A, 8B, and 9, it is assumed that a user requests a function for adjusting a scroll speed. Accordingly, the control unit 120 displays the scroll speed control line 80 on the screen in step S901. An example of a screen displaying the scroll speed adjusting line 80 is illustrated in FIGS. 8A and 8B. As described above with reference to FIG. 4, the scroll speed adjusting line 80 adjusts the scroll speed by adjusting the unit scroll length h. The scroll speed adjusting line 80 illustrated in FIG. 8A represents the unit scroll length h as set in FIGS. 6 and 7. According to this, there is no change in speed during scrolling. However, if the user wants to change the speed when scrolling, the scroll speed may be adjusted by changing the scroll speed adjusting line 80. This is possible by changing a straight line into a curve by dragging after the user touches the scroll speed control line 80 as shown in FIG. 8B. When the scroll speed control line 80 is changed as shown in FIG. 8B, a frame scrolled by the unit scroll length h along the scroll speed control line 80 is displayed every frame display period. Accordingly, reference numeral 81 becomes an acceleration section, and reference numeral 83 becomes a deceleration section. That is, since the scrolling speed is increased by the increased unit scroll length h in the acceleration section 81, the scroll speed is increased. In the deceleration section 83, the scroll speed is decreased by the scroll speed by the reduced unit scroll length h.

When the user completes the scroll speed adjustment through the manipulation of the frame rate adjustment line 80, the controller 120 detects this in step S903 and displays a test page in step S905.

The test page is for testing the scroll speed change by the scroll speed adjusting line 80 changed by the user, and is at least larger than the screen size of the display device. In this page, scrolling is performed for a predetermined length on any touch input. That is, the entire scroll length H is set to a preset reference value. Here, the reference value is a predetermined value for setting the parameter. If the total scroll length H set as the reference value is too long, the amount of computation required to calculate the parameter increases. In addition, when the total scroll length H is too short, it is difficult for the user to accurately recognize the change in the scroll speed. Therefore, it is desirable to set the reference value in advance by finding a suitable value through several experiments.

In the state where the test page is displayed, if there is a user's touch input, the control unit 120 detects this in step S907, scrolls the page by the total scroll length H preset in step S909, displays it on the screen, and stops. The scroll speed is adjusted according to the scroll speed control line 80. Through this step S909, the user can check the scroll speed change that he / she has directly manipulated through the scroll speed adjusting line 80. When the user operates the scroll speed adjusting line 80 in step S903, it is possible to estimate how the scroll speed will change, but the change in the actual scroll speed can be confirmed by scrolling the test page in step S909. For this reason, there may be a difference between what the user himself estimates and the actual, and the user may reconfigure until the user sees the change in the actual scroll speed and is satisfied. If satisfied, the user may enter to confirm that the settings will be maintained, or if not satisfied, to reset to desired settings.

The control unit 120 detects the above-described user input in step S911, and proceeds to step S901 or S913. That is, if there is a reset input, the flow advances to step S901 and the steps S901 to S909 are repeated. On the other hand, if there is an input to confirm, the control unit 120 completes the setting of the scroll speed control line 80 in step S913 and stores. Accordingly, scrolling may be performed by changing the scrolling speed using the scrolling speed adjusting line 80 adjusted by the above-described method.

Next, the screen display method of the terminal according to the parameter setting as described above will be described. 10 is a flowchart illustrating a screen display method of a terminal according to an embodiment of the present invention.

Referring to FIG. 10, it is assumed that the controller 120 displays a portion of a page larger than the display size of the display device 113 on the screen through the display device 113 in operation S1001.

In this case, when the controller 120 detects a user's touch input through the touch sensing device 111 in operation S1003, the controller 120 calculates the entire scroll length H according to the touch input in operation S1005. The overall scroll length H is adjusted according to the touch input. That is, the entire scroll length H increases in proportion to at least one of the pressure detected at the time of dragging or releasing, the speed of dragging, and the length of the dragged area. For example, as the pressure detected at the time of dragging or releasing, the speed of dragging, or the length of the dragged area is longer, the entire scroll length H can be adjusted longer.

When the total scroll length H is calculated, the controller 120 scrolls the page based on the parameter previously normalized in step S1007 and displays the screen on the display device 113. Here, the parameter is set by the method described above with reference to FIGS. 6 and 7 and includes a frame display period f and a unit scroll length h.

During the scrolling, the control unit 120 determines whether there is a scroll stop condition in step S1009, and stops scrolling in step S1011 when a stop condition occurs. Here, the stop condition includes a case in which the user inputs a touch input again during scrolling or a case in which the pages are all scrolled by the entire scroll length H calculated in operation S1005. On the other hand, if there is no stop condition, the control unit 120 returns to step S1007 to continue the process.

Next, a screen display method of the terminal according to another embodiment of the present invention will be described. In this embodiment, the scroll speed adjusting line 80 is further considered as well as performing scrolling based on the parameters set above. 11 is a flowchart illustrating a screen display method of a terminal according to another embodiment of the present invention.

Referring to FIG. 11, it is assumed that the controller 120 displays a portion of a page larger than the display size of the display device 113 on the screen through the display device 113 in operation S1101.

In this case, when the controller 120 detects a user's touch input through the touch sensing apparatus 111 in operation S1103, the controller 120 calculates the entire scroll length H according to the touch input in operation S1105. The overall scroll length H is adjusted according to the touch input and is proportional to at least one of the pressure detected at the time of dragging or releasing, the speed of dragging, and the length of the dragged area.

When the total scroll length H to be scrolled is calculated, as described above with reference to FIGS. 6 and 7, the scroll is performed using the calculated parameters, but eliminating the blurring when the scrolled page scrolls at the same speed and is interesting. In order to provide a user experience, the scroll speed may be adjusted by changing the unit scroll length h during scrolling. It is assumed that the user sets the change of the speed control by using the scroll speed control line 80 in the same manner as described above with reference to FIGS. 8A, 8B, and 9. An acceleration section or a deceleration section may be determined based on the scroll speed control line 80. For example, the acceleration section and the deceleration section may be set as shown in the graphs described with reference to FIGS. 5 and 8B. Here, reference numerals 41 and 81 denote acceleration periods, and reference numerals 43 and 83 denote deceleration intervals.

In order to adjust the scroll speed, the controller 120 determines whether the section of the page currently scrolled is an acceleration section or a deceleration section in steps S1107 and S1111.

In the case of the acceleration section according to the determination of step S1107, the controller 120 increases the unit scroll length h based on the scroll speed adjusting line 80 in step S1109. In the case of the deceleration section according to the determination of step S1111, the controller 120 reduces the unit scroll length h in step S1113. In addition, if it is determined that the acceleration section is not the deceleration section, the control unit 120 maintains the unit scroll length h in step S1115.

As such, after adjusting the unit scroll length h, the controller 120 scrolls according to the unit scroll length h adjusted in step S1117. Then, the speed of scrolling is changed and displayed on the screen.

During such scrolling, the controller 120 determines whether there is a scroll stop condition in step S1119. As a result of this determination, if a stop condition occurs, the scrolling stops in step S1121. Here, the stop condition includes a case in which the user makes a touch input again during scrolling, and a case in which the pages are all scrolled by the entire scroll length H calculated in operation S1105. On the other hand, if there is no stop condition, the controller 120 returns to step S1107 to continue the process.

The screen display method of the present invention described above has the following advantages. First, by normalizing the parameters used for scrolling, it is possible to predict the part of the page to be used for scrolling, so that it is not necessary to preload all the pages, so that the capacity of the memory can be largely used. In other words, when scrolling, the entire page does not need to be loaded into memory and waited for a smooth display. Secondly, only a few necessary frames can be used in advance, which improves the response speed. Third, it is stable by setting parameters in consideration of the comprehensive performance that the terminal can actually display on the screen, not the fractional numerical performance of each device. Fourth, the user's preference is reflected to provide the best screen representation to the user. Fifth, the scroll speed control function is provided to provide an interesting user experience.
