It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the following description, suffixes such as "module", "part", or "unit" used to indicate elements are used only for facilitating the description of the present invention, and have no particular meaning in themselves. Thus, "module", "component" or "unit" may be used mixedly.
The first embodiment is as follows:
the present invention provides a digital display method for a meter, which is applied to an interface presenting a digital variation trend, for example, a display device having a dashboard, such as an automobile, an airplane, and a digital electric meter, and please refer to fig. 1 to 3, and the method includes the following steps:
s101, setting digits required by digital display of the instrument;
specifically, the digital display method includes the steps that the digital display required digits of the instrument are set on equipment on an interface, such as an instrument panel, presenting a digital change trend, of the instrument, wherein the digits include one digit, ten digits, hundred digits, thousand digits, arranged in front of a decimal point, and first digit, ten digits, second digit, and third digit, ten digits and thousands digits after the decimal point, and the number of the digits required to be set specifically can be determined according to actual requirements.
S102, sequentially sorting and fixedly configuring five text elements on each digit in a descending order from top to bottom according to the size of the digits;
specifically, five text elements are fixedly configured on each digit in a descending order from top to bottom according to the numerical value of the number, for example, in table 1 below, 5 text elements are respectively allocated to each digit (one, ten, one hundred.), and the five text elements are respectively set as T1, T2, T3, T4, and T5 and are arranged in sequence from top to bottom, where T3 shows the number X on the current digit, then T1 shows X +2, T2 shows X +1, T4 shows X-1, and T5 shows X-2, so that the numbers displayed on T1 to T5 gradually form a descending sequence arrangement.

| t1 (display X + 2) |
| T2 (display X + 1) |
| T3 (display X) |
| T4 (display X-1) |
| T5 (display X-2) |
S103, calculating the pixel height of each text element;
specifically, the pixel height of each text element can be measured to be H according to actual conditions.
S104, calculating an offset coefficient on each digit; wherein the offset coefficient of the current digit is a number on a digit one digit lower than it;
specifically, the offset coefficient of each digit is calculated, where the offset coefficient of the current digit is a digit on a digit lower than the current digit, for example, when the current digit is a whole offset pixel on a single digit, the first digit after the digit of the decimal point is taken as the offset coefficient of the single digit; when the overall offset pixel with the digit being ten digits is calculated, the digit with the digit being one digit is used as an offset coefficient of the ten digits, and so on.

calculating the pixel height H of each text element on the current digit;
calculating the integral offset pixel L of the five text elements of the current digit according to the offset coefficient P and the pixel height H of each text element; i.e. L = P × H.
For example, when calculating the integral offset pixel with the digit being the unit digit, the first digit after the digit of the decimal point is taken as the offset coefficient P of the unit digit, and the pixel height H of each text element with the digit being the unit digit is calculated; and calculating an overall offset pixel L of the five text elements with the current digit being one bit according to the offset coefficient and the pixel height of each text element, namely L = P H.

when the overall offset pixel L is smaller than the reference number 0, controlling the text element on the current digit to be overall upwardly offset;
and when the overall offset pixel L is larger than the reference number 0, controlling the text element on the current digit to be overall offset downwards.
When the overall offset pixel L is equal to the reference number 0, it indicates that the five text elements on the current digit are offset by an H pixel distance, and the number of the text element originally displayed is displayed by adding 1 or subtracting 1, and is used as the basis for the next iteration display.
After adding 1 or subtracting 1 to the number of the originally displayed text element, T1 to T5 thus form a new number sequence X '+2, X' +1, X '-1, X' -2 (X '= X +1 or X' = X-1). And replacing X with X' in the next iteration and repeating the steps. Thereby achieving the purpose of recycling T1-T5.

s1063, calculating the distance between each sampling point of each text element and the original center line;
s1064, controlling the transparency of the sampling points according to the distance between each sampling point of each text element and the original central line; the smaller the distance, the greater the opacity of the sample point.
Specifically, as shown in fig. 4, five text elements T1, T2, T3, T4, and T5 are regarded as a large drawing area, a transverse center line of T3 is used as an original center line, 3 sampling points A, B, C (respectively corresponding to the top, middle, and bottom of the text element) are calibrated for each text element, and the distance between each sampling point of each text element and the original center line is calculated, wherein the smaller the distance, the greater the opacity of the sampling point.
