Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The embodiment of the present invention provides a kind of screen control method of display device, as shown in Figure 1 to Figure 3, the display dress
It sets including reel 11 and winds the flexible screen 12 being arranged in inside reel 11, flexible screen 12 can export from reel 11 and reach reel
11 outsides are recovered to inside reel 11 outside reel 11；11 exit of reel is provided with photoelectric sensor 13；The method
Include:
Step 101, when flexible screen 12 in reel 11 from when being drawn out or withdrawing into reel 11, it is upper to light flexible screen 12
Three detection light blocks 18 in 11 exit of reel, three detection light blocks 18 are arranged along the pull-out direction of flexible screen 12 and its is bright
Degree successively enhances or successively weakens；Wherein, detection light block 18 and 13 position face of photoelectric sensor are located in the middle.
In practical applications, with reference to shown in Fig. 4 and Fig. 5, three detection light blocks 18 can be close to be arranged.
The embodiment of the present invention for three detection light blocks 18 specific brightness value without limitation, those skilled in the art can be with
It is set according to the actual situation.Exemplary, the grayscale value of three detection light blocks 18 can be respectively 150,100,50；It can also be with
Respectively 200,100,10 etc..For the ease of the preferably detection light intensity variation of photoelectric sensor 13, the ash of three detection light blocks 18
The difference of rank can be set big as far as possible, for example, the grayscale value of three detection light blocks 18 can be respectively 255,128,0.
Referring to figs. 2 to shown in Fig. 5, when flexible screen 12 in reel 11 from when being drawn out or withdrawing into reel 11, light soft
Property screen 12 on be located at 11 exit of reel three detection light blocks 18, at this time in flexible screen 12 be located at three detection light blocks 18 it is separate
The part that reel 11 exports side is lit, and the remainder in flexible screen 12 (is located at 11 inside of reel and includes three inspections
Survey the part of 18 region of light block) it is closed, as shown in uppermost figure in Fig. 4 and Fig. 5, photoelectric sensor 13 and position at this time
In the position face of intermediate detection light block 18.
Step 102, when photoelectric sensor 13 detects that light intensity becomes strong or light intensity dies down, update three detection light blocks 18
Position so that being located in the middle detection light block 18 and 13 position face of photoelectric sensor, and controls in flexible screen 12 positioned at bright
The most weak detection light block 18 of degree is lighted far from the part of strongest 18 side of detection light block of brightness, the rest part of flexible screen 12 closes
It closes.
Refering to what is shown in Fig. 4, the control system of the display device understands the point on blank screen simultaneously when flexible screen 12 is unfolded
Bright three detection light blocks 18, the grayscale of detection light block 18 can be respectively 255,128,0,128 grayscale light block positions just and roll up
Photoelectric sensor 13 on cylinder 11 is corresponding, and when flexible screen 12 is drawn out, 255 grayscale light block positions in flexible screen 12 can replace
128 grayscale light blocks, this makes photoelectric sensor 13 detect that light intensity becomes strong, referring to fig. 4 in be located in the middle a width figure；At this time more
The position of new three detection light blocks 18, so that being located in the middle detection light block 18 (i.e. 128 grayscale light blocks) and photoelectric sensor 13
Position face, and control most strong far from brightness positioned at the most weak detection light block 18 (i.e. 0 grayscale light block) of brightness in flexible screen 12
Detection light block 18 (i.e. 255 grayscale light blocks) side part light, the rest part of flexible screen 12 close, referring to fig. 4 in position
In nethermost width figure.Similarly, when continuing to pull out, three detection light blocks 18 in flexible screen 12 can update again, 128 ashes
The light block of rank corresponds to the position of photoelectric sensor once more, pulls out part in this way and gradually becomes more, flexible screen 12 will be by gradually point
It is bright.
Refering to what is shown in Fig. 5,0 grayscale light block position in flexible screen 12 can replace 128 grayscale when flexible screen 12 is recovered
Light block, this makes photoelectric sensor 13 detect that light intensity dies down, referring to being located in the middle a width figure in Fig. 5；Three are updated at this time
The position of detection light block 18, so that being located in the middle detection light block 18 (i.e. 128 grayscale light blocks) and 13 position of photoelectric sensor just
It is right, and control and be located at the most weak detection light block 18 (i.e. 0 grayscale light block) of brightness in flexible screen 12 far from the strongest detection of brightness
The part of light block 18 (i.e. 255 grayscale light blocks) side is lighted, the rest part of flexible screen 12 is closed, most lower referring to being located in Fig. 5
The one width figure in face.Similarly, when continuing to withdraw, three detection light blocks 18 in flexible screen 12 can update again, the light of 128 grayscale
Block corresponds to the position of photoelectric sensor once more, and such recover part gradually becomes more, and flexible screen 12 will be progressively closed off.By
This, realizes real-time update flexible screen 12 in the way of the 18 rule variation of photoelectric sensor 13 and detection light block and shows image
Function.
So, compared to the prior art, screen control method provided in an embodiment of the present invention passes through setting photoelectric transfer
The sensor three detection light blocks different with brightness, light intensity situation of change is detected using photoelectric sensor, and then judges three inspections
Survey light block situation of movement；According to the pull-out location of the situation of movement real-time detection flexible screen of three detection light blocks, and realize pull-out
While light the flexible screen for pulling out part, extinguish the flexible screen for entering spool portion while withdrawal, realize physical location and
Flexible screen display is synchronous to be carried out, to achieve the purpose that reduce display power consumption and extend flexible screen service life, improves user
Experience.
It should be noted that since detection light block 18 that grayscale is 0 is exactly the state of blank screen, thus in practical applications,
The non-zero detection light block 18 of two grayscale can also be only set, serve as third detection light block using a part in blank screen region
18 function.
