4. The mobile terminal according to claim 1, wherein a free end of the flexible display screen is provided with a long barrier strip, a length of the barrier strip is greater than a length of the elongated opening.

5. The mobile terminal according to claim 1, wherein a front surface of the terminal body is provided with a camera, wherein the control unit is further configured to control the flexible display screen to normally display an image captured by the camera, and when the camera is used for photographing, the control unit is further configured to control the flexible display screen to invertly display the image captured by the camera;

or a back surface of the terminal body is provided with a camera, wherein the control unit is further configured to control the flexible display screen to normally display an image captured by the camera, and when the camera is used for photographing, the control unit is further configured to control the flexible display screen to invertly display the image captured by the camera.

6. The mobile terminal according to claim 1, wherein a bottom surface of the terminal body is provided with a photographing-illumination module, the photographing-illumination module comprises a camera, a flash lamp and a switch wheel, the camera is located in a center of the switch wheel, and the flash lamp is located on a side of the camera and is able to be aligned with flash lenses provided in the circumferential direction of the switch wheel.

7. The mobile terminal according to claim 6, wherein the flash lenses comprise colorless lenses and color lenses, wherein by rotating the switch wheel, the flash lamp is configured to be engaged with different flash lenses so that the flash lamp is able to be used as a normal flash or as a flashlight or as a laser pointer.

8. The mobile terminal according to claim 6, wherein the flash lenses are telescopic zoom lenses, and each of the telescopic zoom lens changes the divergence or convergence effect of the flash lens on the light of the flash lamp through an expansion and contraction of a lens barrel, so that the flash lamp is able to be used as a normal flash and is also able to be used as a flashlight with adjustable irradiation distance.

9. The mobile terminal according to claim 6, wherein the photographing-illumination module comprises a laser lamp, the laser lamp is located on a side of the camera and is configured to be aligned with the flash lenses or a flash transmission hole provided in the circumferential direction of the switch wheel, the control unit is further configured to control the laser lamp to emit light and control the camera to capture an image of an illuminated object, and calculate distance between the camera and the illuminated object according to distance between a bright spot and an image center in a captured image.

10. The mobile terminal according to claim 1, wherein a front surface and a back surface of the flexible display screen are both provided with a touch sensing layer, wherein the control unit is further configured to activate a corresponding touch sensing layer according to different control signals, the different control signals comprises control signals generated according to a specific gesture input on different touch sensing layers and/or control signals generated according to an operation of a function of a specific element within the mobile terminal.

11. The mobile terminal according to claim 10, wherein when the different control signals comprises the control signals generated according to the specific gesture input on the different touch sensing layers and the control signals generated according to the function of the specific element within the mobile terminal, a control priority of the control signals generated according to the operation of the function of the specific element within the mobile terminal is higher than the control signals generated according to the specific gesture input on the different touch sensing layers.
