If the current width of the text box is 4, the current height of the text box is 7. The height conversion coefficient alpha of the display content can be determined according to the size parameters 1 To 4, the width conversion coefficient α of the display contents 2 Is 2. Further, a target height c of the display content can be determined 1 Target width c of the display content, 28 3 Is 8.
In this way, the display size of the display content in the ideal display parameter of the target display is determined by calculating the height conversion coefficient and the width conversion coefficient of the display content, and a data basis is provided for the adjustment of the subsequent display content.

In practical application, when the picture on the computer display screen is adapted to the smart television display screen for display, the computer display screen is the current display screen, and the smart television display screen is the target display screen. When the computer display screen and the intelligent television display screen are vertically placed in a place, the edge closest to the ground is regarded as the bottom edge of the display screen, the edge opposite to the bottom edge is regarded as the top edge, and the two edges adjacent to the bottom edge are regarded as the first side edge and the second side edge respectively. That is, the distance from any point on one edge of the picture to the first side or the second side of the computer display screen is equal to the distance d between the current display screen and the highly-related edge of the display content in the technical scheme 2 (ii) a The distance from any point on one edge of the picture to the bottom edge or the top edge of the computer display screen is equal to the distance d between the current display screen and the edge related to the width of the display content in the technical scheme 4 . It should be understood that d is determined on the picture 2 The same distance between the point and the first side or the second side of the smart television display screen is equal to the distance d between the display content in the technical scheme and the edge related to the height of the target display screen 1 (ii) a Picture and determination of d 4 The same distance between the point and the bottom edge or the top edge of the smart television display screen is equivalent to the distance d between the display content in the technical scheme and the edge related to the width of the target display screen 3 。
In this way, the distance between the target display screen and the edge related to the height of the display content and the distance between the target display screen and the edge related to the width of the display content are determined, and the display area of the display content in the ideal display parameter of the target display is determined, so that a data base is provided for the target display screen to be matched with the subsequent display content.
In some alternative implementations, with reference to fig. 3, an embodiment of the present disclosure provides a flowchart of iterative adjustment, where an electronic device iteratively adjusts a size of display content, where the iterative adjustment includes:
s21, adjusting the height beta of the display content for the ith time i And width delta of display content i 。
S22, determining the height change rate E beta of the display content after the ith adjustment i Sum width change rate E δ i 。
S23, if E beta i Or E delta i Stopping adjusting the height and width of the display content when the positive and negative values change; otherwise, continuing to adjust the height beta of the display content for the (i + 1) th time i+1 And width delta of display content i+1 . Wherein i is a positive integer greater than 0.
Optionally, the height beta of the display content is adjusted for the ith time i The method comprises the following steps:
calculating beta i ＝β i-1 +e i1 Obtaining the height beta of the ith adjusted display content i ；
Wherein beta is i-1 Indicating the height of the display content adjusted i-1, e i1 And the ith time is represented as the height iterative adjustment step of the display content.
Optionally, the width delta of the display content is adjusted for the ith time i The method comprises the following steps:

Wherein, delta i-1 Indicating the i-1 th adjustment of the width of the display content, e i2 And the ith iteration adjustment step of the display content width is shown.
In this solution, it should be understood that e i1 And e i2 The value of (b) may be a positive or negative number.
In practical application, when the text box on the computer display screen is adapted to the display screen of the mobile phone for display, the computer display screen is the current display screen, and the mobile phone display screen is the target display screen. It should be understood that the height β of the display content is adjusted at the beginning of the ith time i And width delta of display content i In the prior art, the height value of the text box is equivalent to the height of the text box in a computer display screen, and the width value of the text box is equivalent to the width of the text box in a mobile phone display screen. In practical application, the height beta of the display content is adjusted at the beginning of the ith time i And width delta of display content i Before, if the height of the text box is 50 and the width of the text box is 30, the step length e for iteratively adjusting the height of the display content for the first time is determined 11 The value is minus 10, the step length e of the second time of the iterative adjustment of the height of the display content 21 The value is minus 5, the iterative adjustment step length e of the first width of the display content 12 The value is negative 6, the first time width iterative adjustment step length e of the display content 22 The value is minus 3. Then after the first adjustment the corresponding beta 1 The value is 40, delta 1 Value 24, corresponding to beta after the second adjustment 1 The value is 35, delta 1 The value is 21, and the rest adjustment results are analogized in the same way.
Alternatively, e i1 、e i2 Proportional relation of (c) to beta 0 、δ 0 The same is true.
Wherein, beta 0 Height, delta, indicating the display content in the current display screen 0 Indicating the width of the display content in the current display screen.
In some alternative embodiments, e i1 And e i2 The value of (b) may be predetermined.
Alternatively, e i1 And e i2 The value of (c) may be fixed.
Alternatively, e i1 And e i2 The value of (d) may not be fixed.
In some alternative embodiments, e i1 Satisfies | e i1 | is greater than | e i+11 |，e i2 Is taken to satisfy | e i2 | is greater than | e i+12 |。
In practical applications, it should be understood that e is the starting phase of an iteration in order to reduce the number of operations of the electronic device i1 And e i2 Should be greater than e before the iteration stops i1 And e i2 Is the absolute value of the value of (a), i.e. e 11 Is greater than e 21 Absolute value of (d); e.g. of the type 12 Is greater than e 22 The absolute value of (c).
Therefore, the width and the height of the display content in the current display screen are the same as the width and the height of the display content in a proportional relation, the height iterative adjustment step length and the width iterative adjustment step length are used for adjusting the width and the height of the display content, and the equal proportional adjustment of the display content can be guaranteed, so that the influence caused by picture distortion is effectively reduced, the accuracy of adjustment control is improved, and the user experience is improved.
Optionally, the electronic device determines the high degree change rate E β of the display content in the following manner i And rate of change of sum width E δ i ：
Calculating out
And obtaining the height change rate of the display content after the ith adjustment. Wherein t is the sampling period of the iterative adjustment.
Optionally, the electronic device determines the rate of change of the width E δ of the display content in the following manner i ：
Computing
And obtaining the width change rate of the display content after the ith adjustment. Wherein t is the sampling period of the iterative adjustment.
In practical application, if E beta i Or E delta i If the change of the positive and negative values occurs, the adjustment of the height and width of the display content is stopped, which can be understood as the judgment of E beta i-1 And E beta i Positive or negative value state of, or judgement of, E delta i-1 And E delta i Positive and negative value of (E) at E beta i-1 And E beta i Or E.delta i-1 And E delta i When the positive and negative values of the display content are changed, the adjustment of the height and width of the display content is stopped. It should be understood that in the process of adapting from the current display to the target display, if the size of the current display is smaller than that of the target display, each iteration adjusts E β i And E delta i Is a gradual decreasing process; if the size of the current display screen is larger than that of the target display screen, E beta is adjusted in each iteration i And E delta i Is a gradual rising process. At E beta i Or E delta i In the case of a change in the positive or negative state of one of the two, i.e. the changed E β i Or E delta i And the height of the corresponding adjusted display content or the width of the display content reaches or exceeds the display size. It should be understood that at E β i Or E delta i When a certain term is zero, it is equivalent to Ebeta i Or E delta i The width or height of the corresponding display content achieves the ideal display parameters of the display content on the target display screen.
Therefore, by judging whether the positive and negative states of the height change rate or the width change rate of the display content after the ith adjustment change, and taking the positive and negative states as termination conditions for stopping the iterative adjustment process of the display content, the data oscillation generated when the display content cannot reach the display size in the ideal display parameters of the target display screen under the condition of no distortion can be effectively avoided.
In conjunction with fig. 4, another method for automatically adapting a display screen is provided in an embodiment of the present disclosure, which includes:

In practical application, it should be understood that, after the size of the display content is adjusted in the first iteration, the size of the display content reaches or approaches to the display size, that is, the positive and negative state changes of the height change rate and the width change rate of the display content adjusted in the first iteration can be understood as that the size of the display content approaches to the display size.
And S36, the electronic equipment performs second iterative adjustment on the current size of the display content so that the display content is displayed in the display area according to the display size.

In the present technical solution, the fixed coefficient may be 17%,20%,5% or other values, which is not specifically limited in the present application.
In practical application, if the display content height iterative adjustment step size is 20, the display content width iterative adjustment step size is 15, and the fixed coefficient value is 10% in the first iterative adjustment stop state, the display content height second iterative adjustment step size is 2, and the display content width second iterative adjustment step size is 1.5.
Therefore, the ideal display parameters of the display content on the target display screen are determined by obtaining the size parameters of the target display screen and the display parameters of the content to be displayed on the current display screen, the change rate of the width and the height in the adjustment process of the display content is calculated, and the display content is subjected to twice different iterative adjustments, so that the influence caused by picture distortion is further reduced, the accuracy of adjustment control is improved, and the user experience is improved.
In some alternative implementations, as shown in fig. 5, an embodiment of the present disclosure provides another flowchart of iterative adjustment. And the electronic equipment performs second iterative adjustment on the current size of the display content, and the second iterative adjustment comprises the following steps:
s41, adjusting the height beta of the display content for the jth time j And width delta of display content j 。
