Under, screen is divided into several screen pixels regions using 7*7 as minimum text display unit, each pixel region includes 7*7
On-screen display (osd) area can be divided into several scan lines by pixel-matrix after division, every row includes 7 pixel rows, (every line by line
7 pixel rows) it is scanned detection, word for word (every 7*7 pixel-matrix) is detected in every one scan line, judges that screen is saturating
Penetrate intensity of illumination；It optionally, is the resolution ratio and detection efficiency of taking into account chinese disply clarity, optical sensor, it can also be with 16*
16 pixel-matrixs, 32*32 pixel-matrix or other pixel-matrixs are basic scanning element, line by line (for example, every 16 pixel-matrix row
Or every 32 pixel-matrix rows) word for word (for example, every 16*16 pixel-matrix or every 32*32 pixel-matrix) be scanned；For example,
It can also be using 32*32 pixel-matrix as the minimum screen pixels region of detection spot, from top to bottom by display screen, by every 32*
32 pixels will show that screen divides several pixel regions；When detecting spot, using every 32 pixel-matrix row as row scanning basis,
It is progressively scanned from top to bottom, again using every 32*32 pixel-matrix as basic screen pixels region in every one scan line, by
Word is scanned, and detects the transmission intensity of illumination in each screen pixels region, is less than with judging whether there is transmission intensity of illumination
The screen pixels region of preset threshold.
Screen stained region, it may be possible to a screen pixels area size (such as 32*32 pixel-matrix) divided in advance,
It is also likely to be the stained region block of multiple continuous screen pixels region compositions, it is also possible to multiple mutually unrelated screen pictures
Plain region or stained region block, as long as the size for suitably dividing screen pixels region can be detected discovery.
It, can be by showing content detection for being less than the screen pixels region of the preset threshold when transmission intensity of illumination
Module detects the corresponding display caching area of the pixel region, if what is saved in corresponding display caching area is that text shows data
(reading display content), then the content of text in display caching area can be changed to cross by common static status display by display control module
To the scrolling display of word for word ring shift left, text can be made to show that content avoids the stained region by way of rolling in this way,
Consequently facilitating the content blocked when user clearly reads original static status display by spot.
For example it is assumed that spot only has at one and stained region is little, content (such as English just is shown in covering a line text
Text, number or Chinese character) in one or more text characters, this display of the style of writing can be changed to by original static status display
Dynamically Announce, i.e., showing content to the text of the row, word for word ring shift left is moving to left to make the text character being originally blocked
Can have an opportunity to be displaced to the clean area of display screen in the process, so that user clearly reads.It is corresponding according to screen stained region
Buffer area content of text concrete condition, ring shift left is carried out with the minimum display unit of corresponding text.
It, can will be in the display caching of corresponding region when the continuous multirow of the bigger covering of the stained region shows content
Hold, according to general reading habit, word for word ring shift left line by line from top to bottom.
Screen spot provided by the invention copes with device, shows content when mobile terminal screen influences text there are spot
When clear reading, related text can be shown that content be changed to scroll by static status display automatically, to make screen stained area
The corresponding text in domain shows that content is possibly removed stained region, so as to user's reading, improves the experience of user.

Below with an exemplary embodiment, the present invention is further detailed.
As shown in fig. 6, this exemplary embodiment the following steps are included:
Step 10: the mobile phone power-on with touch display screen, equipment, which is in, unlocks bright screen state；
Step 11: the transmission intensity of illumination of detection mobile phone display screen curtain；
With the pixel region that the text of minimum detectable is shown, for example, 32*32 pixel-matrix row to on-screen display (osd) area into
Row divides, using every 32*32 pixel-matrix as basic unit (the i.e. screen pixels area of detection mobile phone screen transmission intensity of illumination
Domain), the transmission intensity of illumination of (every 32 pixel-matrix row) word for word (every 32*32 pixel-matrix) Scanning Detction mobile phone screen line by line；
Basis of i.e. every 32 pixel-matrix row as row Scanning Detction, from left to right or is from right to left word for word scanned, judges to transmit
Intensity of illumination；
Step 12: judge the screen pixels region (i.e. 32*32 lattice pixels block) detected transmission intensity of illumination whether
Less than minimum threshold needed for meeting text reading? if so, step 13 is connect, if not, terminating.
For example, it is assumed that chinese disply dot matrix is 32*32, it can be in 32 pixel-matrix rows word for word scanning process, as long as depositing
With the approximate spot of 32*32 pixel-matrix size, can be detected.For example, have spot at one in Fig. 7 on display screen,
It is close to cover 1 Chinese character；When being progressively scanned with 32 dot matrix rows, and word for word scan in row with 32*32 dot matrix, hold
The transmission intensity of illumination of easily one screen pixels region (i.e. 32*32 dot matrix region) of discovery is less than preset threshold (i.e. text reading
Required minimum threshold), it can be determined that a stained region；
Have spot at two in Fig. 8 on display screen, be covered each by 3 rows and 4 row Chinese characters, with 32 dot matrix rows from top to bottom into
When going and progressively scan, and word for word scan in row with 32*32 dot matrix, it can be found that there is the transmitted light in multiple screen pixels regions
It is less than preset threshold (i.e. minimum threshold needed for text reading) according to intensity, is believed according to the position in this multiple screen pixels region
Breath, it can be determined that it is neighboring screens pixel region out, i.e. stained region 1；It continues to scan on, can find again and has multiple screens
The transmission intensity of illumination of pixel region is less than preset threshold, is believed according to the position in these multiple screen pixels regions found again
Breath, it can be determined that be another place's neighboring screens pixel region, i.e. stained region 2 out；Stained region 1 and stained region 2 are mutually not
Association, is independent stained region at two.
Step 13: transmission intensity of illumination is corresponding less than the screen pixels region for the minimum threshold for meeting text reading needs
Whether display caching area, which has text, shows content (content of text i.e. to be shown, such as western character, number, Chinese character),
If any connecing step 14；If not, going to step 15, routinely display mode shows related content, terminates.
Step 14: the text in the display caching area is shown that content carries out ring shift left line by line on screen corresponding region and moves
State is shown.
Here, can be with western character or the display pattern of number if it is western character or number, word for word circulation is left line by line
It moves；If it is chinese character, then chinese disply mode is pressed, line by line word for word ring shift left Dynamically Announce.It is mixed if it is Chinese and western language
It has been shown that, by common static status display module, is changed to line by line a word for word circulation left side then using Chinese character as the basic unit of row display
The Dynamically Announce of shifting.
For example, as shown in Figure 7, it is assumed that the spot on display screen covers a Chinese character, leads to a line as shown in Figure 7
Text, which can not understand, to be read；Then content can be shown according to the corresponding text in the row display caching area, to the row text carry out by
Word ring shift left shows one time, for example, will ", band protective case or even using have " word for word ring shift left, such as → " band protective case is
To using have, " → " protective case so using have, band " ... → ", band protective case or even using having ", Dynamically Announce one time, from
And by the Chinese character that originally can not be clearly read under spot (being herein " being " word), stained region is dynamically removed, user is facilitated to read
It reads.
Here, if detection discovery screen transmission intensity of illumination is less than the screen for meeting the minimum threshold of text reading needs
Pixel region has many places, then whether the display caching area for needing to detect each screen pixels region respectively has in text shows
Holding, each screen pixels region for showing content for there being text is respectively processed according to the sequence of screen from top to bottom,
Content wherein is shown to the text of each screen associated pixel region, according to row sequence from top to bottom, word for word circulation is left line by line
Dynamically Announce is moved, is consistent with the usual reading habit of user；When being related to multiple screen stained regions, the dynamic of each stained region
Display carries out in turn, can be with reciprocation cycle, until receiving ceasing and desisting order for user's input；And for being stored in display caching area
The screen stained region of non-textual display content, then routinely display mode is handled.
For example, as shown in figure 8, the detection of spot detection module judges to find to transmit intensity of illumination on screen at two less than default
The region unit (stained region) of threshold value, as shown in stained region block 1,2 in figure, this at two stained region it is discontinuous；For spot
Region unit 1, it is similar with Fig. 7 a line Chinese character Dynamically Announce of foregoing description, herein since detection discovery stained region block 1 is by more
A adjacent screen pixels region composition, to constitute stained region block bigger than Fig. 7 at one, needs to detect stained area respectively
Whether the display caching area in each screen pixels region that domain block 1 is related to, which has text, shows content, for example, can be directed to each
The corresponding display caching area in screen pixels region detects whether that having text shows content, and it is corresponding also to can detecte stained region
Row display caching area judges whether that having text shows content.By detection it can be found that the corresponding display of stained region block 1 is slow
Deposit area and have three row texts, then need from top to bottom, line by line word for word ring shift left one time, for example, first for ", band protective case, be
Have to using " word for word ring shift left one time；Then it is being directed to " anti-fingerprint pad pasting etc. high-tech side " word for word ring shift left one time；
For " formula to protect mobile phone, still, no " also similarly word for word ring shift left one time；Then, it is related to for stained region block 2
4 row texts, also carry out similar dynamic display processing.
If being not received by ceasing and desisting order for user's input, progress, i.e., 3 rows of first stained region block 1 can be recycled
Text Dynamically Announce one time line by line；4 row texts Dynamically Announce one time line by line of stained region block 2 again；Then repeat area again
Domain block 1 ...
Step 16: whether the screen area of Dynamically Announce detects the stop signal of user's input line by line, such as, if inspection
Measure user's point touching screen；If so, connecing step 17, if not, going to step 14, retransmits and carry out Dynamically Announce.
Step 17: stopping Dynamically Announce, restore conventional display mode (i.e. static status display mode), terminate.
For example, if user 1 related text of stained region block (or 2 related text of stained region) Dynamically Announce process
In, the scrolling display region of display screen is clicked, then Dynamically Announce process terminates, and is restored to conventional display.
