In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
Example 1:
as shown in fig. 1, the present invention provides a text display position control method for an OLED, the method including:
rasterizing a display area, wherein each grid corresponds to a display subarea containing a plurality of pixels;

The beneficial effect of this embodiment does:
the method comprises the steps of rasterizing a display area to enable each grid to correspond to a display subarea comprising a plurality of pixels, classifying the display subareas based on the aging degree of each display subarea, determining an alternative display area based on the position of each display subarea with low aging degree in the display area, segmenting a text to be displayed to obtain a plurality of text segments, and obtaining text segment information based on a preset rule; and finally, selecting an alternative display area corresponding to each text fragment as a target display area based on the text fragment information. The method and the device consider the importance degree of each part of the content in the text to be displayed, namely the display weight, select the appropriate target display area for each text segment based on the display weight, display the content by using the display subarea with low aging degree on the premise of not missing important content, avoid the aging problem caused by long-time display of part of the area, and further avoid the screen burning phenomenon.
The following describes the implementation process of the embodiment of the present invention in detail:
and S1, rasterizing the display area, wherein each grid corresponds to a display partition containing a plurality of pixels.
Taking the display screen of the smart watch as an example, as shown in fig. 2, the display area may be rasterized according to a preset rule, where a square area formed by each dotted line in the drawing is a grid, and there are W1 × H1 grids, and each grid includes W2 × H2 pixels.
Assuming that the watch screen pixels are 320 × 300, the number of horizontal pixels and the number of vertical pixels of each grid are the same, i.e., W2=10 pixels, H2=10 pixels, then W1=32, H1=30, i.e., 32 × 30 grids in total.
Classifying the display sections based on the aging degree of each display section.
S2.1, under the premise of certain display brightness, the total duration of pixel luminescence is an important parameter influencing pixel aging, so that the total duration of the display area can be obtained by timing and accumulating when displaying in a display subarea every time;
s2.2, sorting the display partitions in a descending order according to the total display time, calculating the average total display time t1 of the first n display partitions, and recording the aging degree of the display partitions as high; in specific implementation, N/N is greater than or equal to 10%, wherein N is the total number of display partitions, namely W1H 1.
S2.3, taking the value of t1-t2 as a dividing standard of the middle aging degree and the low aging degree, and classifying the rest display subareas, namely distinguishing the display subareas of the middle aging degree and the low aging degree, wherein t2 represents a preset time interval, is an empirical value, is related to screen materials and default display brightness, and is preset manually. And the value of t1-t2 is a dynamically changing value that is related to the current degree of aging.
And dividing a plurality of rectangular areas based on the positions of the display subareas with low aging degrees in the display area, wherein each rectangular area is used as a standby display area.
S3.1, recording the display subarea with low aging degree as 1, and recording the display subareas with medium aging degree and high aging degree as 0; the display partition can be converted into a binary image;
s3.2, extracting the edge image of the binary image to obtain a plurality of closed polygons;
in addition, if other polygons B exist in a certain polygon a, the number of display partitions occupied by the multi-deformation B is calculated, and if the number of display partitions is smaller than a preset threshold value, such as the number of display partitions smaller than 2, only the polygon a is reserved, and the polygon B is rejected.
S3.3, using the conventional algorithm for finding the maximum rectangle in the horizontal direction inside any polygon, one maximum rectangle (solid line portion) embedded in the polygon as shown in fig. 3 is obtained, and the rectangular region is used as the candidate display region, which may be denoted as S = W3 × H3, where W3 denotes the number of grids corresponding to the width of the candidate display region, and H3 denotes the number of grids corresponding to the height of the candidate display region.
And performing word segmentation on the text to be displayed to obtain a plurality of text segments, and obtaining text segment information based on a preset rule. The text segment information includes at least the number of characters of the text segment and the corresponding display weight.
Taking date display commonly seen in a smart watch as an example, assuming that a text to be displayed is yyy year, mm month and dd day, three text segments can be divided by an existing word segmentation technology, namely, "yyy year", "mm month" and "dd day", text segment information of "yyyy year" can be { 5, 0, 1 }, wherein 5 represents the number of characters in the text segment, 0 represents the type of the text segment as year (the value of which can be 0, 1 and 2 respectively represent year, month and day), and 1 represents a display weight corresponding to year (the value of display weight can be 1, 2 and 3, the larger the information is, the more important the information is, priority display is required, based on the daily requirement of people for viewing dates, the lowest display weight of year is 1, the next display weight of month is 2, and the highest display weight of days is 3).
For another example, taking the common time display in the smart watch as an example, assume that the text to be displayed is hh: mm: and ss, three text segments can be divided, namely 'hh', 'mm' and 'ss', and the text segment information of 'mm' can be { 2, 1, 3 }, wherein 2 represents the number of characters, 1 represents the type of the text segment as minute (the values can be 0, 1 and 2 respectively represent time, minute and second), and 2 represents the display weight corresponding to the minute (the values of the display weight can be 1, 2 and 3, the larger the information is, the more important the information is, the priority display is needed, the display weight of time can be 3, the display weight of minute is 2, and the display weight of second is 1 based on the habit and the requirement of people for daily watching time).
Obviously, different types of texts to be displayed can be matched by setting multiple preset rules, so as to improve the application range of the embodiment.
After the weight and the character content of each text segment are determined, the candidate display areas corresponding to the number of the text segments need to be screened out from the plurality of candidate display areas, so that the content of the text segments is correspondingly displayed in the candidate display areas. However, when selecting the candidate display region, it is necessary to consider the relationship between the display weight and the size of the display area, and to make the content with a large display weight more visible. Thus:
and S5, selecting the alternative display area corresponding to each text fragment as the target display area based on the text fragment information.
S5.1, acquiring optional character sizes and the number of grids occupied by single characters corresponding to each character size; for example, three levels of character sizes, i.e., large, medium, and small, are preset in the device, and each character occupies 1 grid in the small character size; at medium character size, each character occupies 2 × 2 grids, and at large character size, each character occupies 3 × 3 grids.
And S5.2, determining the character size of each text segment based on the display weight, and acquiring the required grid number of each text segment under the corresponding character size.
Since important information requires a better display effect, the larger the display weight of the text segment is, the larger the character size is used.
Taking date display commonly seen in smartwatches as an example, assuming that the text to be displayed is day 23/01/2001, and the display weight of the text segment "day 23" is the highest, the size of the used characters is large, and the characters include 3 characters "2", "3", and "day". The grid required to display "23 days" at large character size can be calculated, i.e. the required grid is 3 x 3+3 x 3=9 x 3 at large character size;
likewise, "01 month" requires a grid of 2 x 2+2 x 2=8 x 2 at the middle character size; in "2001", the grid required was 1 × 1+1 × 1=5 × 1 at a small character size.
Obviously, the optional character size is determined by the device system setting, and there may be more optional sizes as long as the larger the display weight of the text segment is, the larger the character size is used.
And S5.3, determining the alternative display area corresponding to each text segment as the target display area based on the required grid number, the display weight priority principle and the grid utilization rate priority principle of each text segment.
S5.3.1, screening out candidate display areas meeting the conditions based on the display weight priority principle and the required grid number of the text segments;
the eligible candidate display areas are: the internal grid is sized to completely display the alternate display region of the text segment. Specifically, according to actual needs, the text fragment may be further divided, for example, "23 days" may further divide "23" and "days", so that the required grid is converted from an original rectangular region of "9 × 3" into a region formed by combining a rectangle of "6 × 3" and a rectangle of "3 × 3", so as to adapt to more alternative display regions and improve the utilization rate of pixels. And the display weight priority principle is as follows: and sorting the text segments in a descending order according to the display weight, and after the text segment which is sorted at the front determines the target display area, determining the target display area for the text segment which is sorted at the back.
In addition, for the case that a plurality of candidate display areas meeting the conditions exist, the method can further comprise the following steps:
s5.3.2, if there are a plurality of candidate display areas that meet the conditions, the candidate display area with the highest grid utilization rate is selected as the target display area based on the grid utilization rate priority rule.
In addition, in order to further utilize the alternative display area, the following steps can be further included:
s5.3.3, if the number of the remaining candidate display areas is not greater than the text segment of the undetermined target display area, before acquiring the target display area of the next text segment, deleting the grids displaying characters in the determined target display area from the display subareas with low aging degree to update the display subareas with low aging degree, and further executing S3 again to obtain a new candidate display area, so that the selection of the next target display area can be obtained based on the updated candidate display area.
For example, as shown in fig. 4, displaying "23 days" requires a grid of "9 x 3" and the alternative display area is a grid of "9 x 5", where there are grids for displaying characters (shaded portions) and grids for not displaying characters, and it is possible that the grids for not displaying characters may be used for the display of the next text segment. Also, the grid utilization rate is a ratio of the number of grids for displaying characters in the target display area to the number of grids of the target display area.
