When the first flexible screen 120 is outside the device housing 110, the touch module 141 detects a touch signal generated on the first flexible screen 120, where the touch signal includes both a touch signal generated by the elastic ground conductor 130 on the first flexible screen 120 and a touch signal generated by a finger or a palm on the first flexible screen 120, and since the elastic ground conductor 130 has a specific shape, the touch module 141 can recognize the touch signal generated by the elastic ground conductor 130 from the touch signal generated on the first flexible screen 120 according to the shape of the elastic ground conductor 130.

Therefore, in some possible implementations, as shown in fig. 7, the touch module 141 may further include: a detection unit 1411, an identification unit 1412 and a calculation unit 1413. The detecting unit 1411 detects a touch signal generated on the first flexible screen 120. The identification unit 1412 identifies the touch signal generated by the elastic ground conductor 130 on the first flexible screen 120 according to the distribution of the touch signal on the first flexible screen 120 based on the shape of the elastic ground conductor 130. The calculation unit 1413 determines coordinates of the elastic ground conductor 130 on the first flexible screen 120 according to the touch signal generated by the elastic ground conductor 130 on the first flexible screen 120, and determines the length of the first flexible screen 120 outside the device housing 110 according to the coordinates.

In some optional examples, the first flexible screen 120 may include a capacitive multi-point touch sensing panel, and the elastic ground conductor 130 may include a spring and a metal strip, the metal strip is in contact with the capacitive multi-point touch sensing panel above the first flexible screen 120 under the elastic force of the spring to cause a change in capacitance formed by the touch electrodes in the touch sensing panel, and the change in capacitance in the touch sensing panel generates a touch signal. As shown in fig. 8, in the capacitive multi-point touch sensing panel of the first flexible screen 120, the touch electrodes may be arranged in an MXN matrix, the touch electrodes may be diamond-shaped electrodes made of ITO material, wherein the longitudinal electrodes may be receiving electrodes RX as an X axis, the transverse electrodes may be driving electrodes TX as a Y axis, RX and TX may be respectively connected to the detecting units 1411 in the touch module 141 on the FPC, and the metal strip 131 in the elastic ground conductor 130 may be a metal strip with a length of M electrode channels and a width of 2 electrode channels.

As an alternative example, M is 15 electrode channels, N is 20 electrode channels, and the touch signal generated on the touch sensing panel is as shown in fig. 9A, wherein the metal strip 131 generates the touch signal on the 7 th and 8 th electrode channels in the transverse direction and the 1 st to 15 th electrode channels in the longitudinal direction of the touch sensing panel. The identification unit 1412 in the touch module 141 may identify, based on the shape of the metal strip 131, that the length occupies the entire Y axis, and the width is narrower in the X axis, that is, the length is 15 electrode channels, and the width is 2 electrode channels, and according to the distribution of the touch signals on the touch sensing panel, the touch signals of the 7 th and 8 th electrode channels in the transverse direction and the 1 st to 15 th electrode channels in the longitudinal direction of the touch sensing panel are the touch signals generated by the metal strip 131 on the touch sensing panel.

Optionally, the identifying unit 1412 may further perform binarization processing on the detected touch signal generated on the first flexible screen 120, and identify the touch signal generated on the first flexible screen 120 by the elastic ground conductor 130 according to the distribution of the binarized touch signal on the first flexible screen 120 based on the shape of the elastic ground conductor 130.

As shown in fig. 9B, by performing binarization processing on the touch signal generated on the touch sensing panel in fig. 9A, the touch signal generated on the touch sensing panel by the metal strip 131 can be marked as 1 after binarization processing, so that based on the shape of the metal strip 131, the touch signal generated on the touch sensing panel by the metal strip 131 can be recognized by only determining the position marked as 1 in the touch sensing panel.

As another alternative example, M is 15 electrode channels, N is 20 electrode channels, and the touch signal generated on the touch sensing panel is as shown in fig. 10A, wherein the metal strip 131 generates the touch signal on the 2 nd and 3 rd electrode channels in the transverse direction and the 1 st to 15 th electrode channels in the longitudinal direction of the touch sensing panel, and the finger generates the touch signal on the 12 th to 14 th electrode channels in the transverse direction and the 8 th to 10 th electrode channels in the longitudinal direction of the touch sensing panel. The identifying unit 1412 in the touch module 141 may identify, based on the shape of the metal strip 131, that the length occupies the entire Y axis, and the width is narrower in the X axis, that is, the length is 15 electrode channels, and the width is 2 electrode channels, and according to the distribution of the touch signals on the touch sensing panel, the touch signals of the transverse 2 nd and 3 rd electrode channels and the longitudinal 1 st to 15 th electrode channels on the touch sensing panel are identified, and are the touch signals generated by the metal strip 131 on the touch sensing panel, and based on the shape of the finger, that the ratio of the length to the width is about 1:1, and according to the distribution of the touch signals on the touch sensing panel, the touch signals of the transverse 12 th to 14 th electrode channels and the longitudinal 8 th to 10 th electrode channels of the touch sensing panel are identified, and are the touch signals generated by the finger on the touch sensing panel.

Alternatively, as shown in fig. 10B, the touch signal generated on the touch sensing panel in fig. 10A may be further binarized, so that the effective touch signal generated on the touch sensing panel is greater than the preset signal threshold and is marked as 1, even though the touch signals generated on the touch sensing panel by the metal strip 131 and the finger are both marked as 1 after the binarization processing, based on the shape of the metal strip 131, the touch signal generated on the touch sensing panel by the metal strip 131 can be recognized only by judging the position marked as 1 in the touch sensing panel, and the touch signal generated on the touch sensing panel by the finger can be recognized in the same way, so as to distinguish the touch signals generated on the first flexible screen 120 by the metal strip 131 and the finger, since the invalid signal generated on the touch sensing panel does not need to be judged again after the binarization processing is performed on the touch signal, therefore, the identification process of the touch signal can be simplified.

Alternatively, the calculation module 1413 may determine the coordinates of the elastic ground conductor 130 on the first flexible screen 120 by a gravity center method according to the touch signal generated by the elastic ground conductor 130 on the first flexible screen 120; alternatively, the calculation module 1413 may also determine the coordinates of the elastic ground conductor 130 on the first flexible screen 120 according to the channel number of the touch electrode where the elastic ground conductor 130 generates the touch signal on the first flexible screen 120 and the resolution of the first flexible screen 120; the embodiment of the present application does not limit the implementation manner of determining the coordinates of the elastic ground conductor 130 on the first flexible screen 120.

Alternatively, the calculating unit 1413 may calculate, according to a gravity center method, a coordinate 735 on an X axis of the touch sensing panel by X ═ [ (35+45+47+49+51+54+54+52+52+51+49+47+45+40+31) × 7+ (11+16+19+24+26+29 +32+34+37+41+47+53+59+ 55)/(35 +45+47+49+51+54+54+52 +51+49 +45+40+31+11+16+19+24+26+29+31+32+34+37+41+47+53+59+ 55))/(where ((702 + 7+ 514)/(702 + 514)))/(9029/1216) × 99 ═ 735.091, where 7 is the coordinate 735 on the X axis of the 7 th electrode channel, 8 is the number of the 7 th electrode channel, and the total number of the electrode on the X axis is 20, 1980 is the number of pixels in the X-axis direction in the resolution of the first flexible screen 120; alternatively, the calculating unit 1413 may calculate, according to the channel number and the resolution of the touch electrode, a coordinate 742.5 of the metal strip on the X axis of the touch sensing panel by using X ═ [ (7+8)/(2 × 20) ] × 1980 ═ 742.5, where 7 is the channel number of the 7 th electrode channel and 8 is the channel number of the 8 th electrode channel, and may determine, according to (7+8)/2, that the center channel number is 7.5, 20 is the total number of electrode channels on the X axis, and 1980 is the number of pixels in the X axis direction in the resolution of the first flexible screen 120.
