Scan line and touch control detection line are set parallel to each other, and its bearing of trend is parallel to the curved of the foldable area of flexible touch screen
Bent axle.Therefore, when being folded according to the flexible display screen of the application, it is not easy to the situation of foldable area damage occur.
According to embodiments herein, when flexible display screen does not bend, the flexible display screen can be carried out entirely
Screen display, and when flexible display screen bends, it is arranged on the not foldable area of both sides（That is, first area）In extremely
One of them can be without display less.
In one embodiment, when flexible display screen bends, it is arranged on one in the not foldable area of both sides
It is individual without display（For example, right side area）, it is arranged on another in the not foldable area of both sides（For example, left field）
Keep display with the foldable area of centrally disposed part, and whole display contents in full screen display remap to
The part of the holding display of the flexible display screen.
In another embodiment, when flexible display screen bends, it is arranged on the not foldable area of both sides not
It has been shown that, the foldable area of centrally disposed part keeps display.
Fig. 7 schematically shows the working condition in bending according to the flexible display screen of the application one embodiment.
As shown in fig. 7, when left field and right side area are all without display, only middle section is shown.This
When the touch function of left field and right side area can be also switched off, realize further power-save operation.
In addition, when flexible display screen is in non-folded state, first area（E.g., including left field and right side region
Domain）And second area（For example, middle section）The coordinate position of the touch point in respective region can be read respectively, and is fed back to
Control unit（It is not shown）.Coordinate respectively from first area and the touch point of second area is mapped to entirely by control unit
In the coordinate system of display screen, so that the coordinate position of the touch point formed on whole display screen.
When flexible display screen is in folded state, different from the example shown in Fig. 7, a part of screen can be closed, and
Another part screen can continue to keep display.For example, when display screen is in folded state, left field and middle section are carried out
It has been shown that, and right side area is not shown.Now, the touch function of right side area can be closed, i.e. touch-control scan line TX/ touch control detections
Line RX stops scanning, can so play a part of power saving.Now, the touch point coordinates of left field and middle section is reflected again
Display screen is mapped to, to obtain the coordinate position of corresponding touch point.Alternatively, can not when closing a part of screen
Carry out the scaling of display screen.For example, left field can show as main viewing area, middle section as the center of independent control
Show region to realize additional function.For example, central display area can show time or customized information etc..
According to the flexible display screen of the application, the various displaying schemes under folded state can be realized as needed, are had
Flexibility.When being bent according to the flexible display screen of the application, be arranged in the not foldable area of both sides at least its
One of therefore can further save electric power without display.
Although having been shown and illustrating each embodiment according to the application, those of ordinary skill in the art should manage
These exemplary embodiments can be made various changes and be wanted without departing from by appended right by solution in terms of form and details
The spirit and scope that the application for asking book to limit conceives.
