Embodiment 1

[0030] Such as figure 1 As shown, the present embodiment provides a mobile terminal (such as a mobile phone), the mobile terminal has a flexible display screen, and the flexible display screen has a supporting carrier 1 formed of a soft-hard material, including a housing that is also made of a soft-hard combination. Composed of materials, the mobile terminal includes a bending unit for bending the flexible display along a bending path, the bending unit includes a voltage controller (not shown in the figure) and along the A plurality of bending mechanisms arranged on the bending path, each bending mechanism includes an electrode (not shown in the figure) and a cavity 2 extending in a direction perpendicular to the bending path, and the cavity 2 extends along it The two ends of the direction are fixed on the flexible display screen, the cavity 2 is filled with liquid metal, the top of the cavity 2 is provided with a deformable top cover for sealing the liquid metal, the cavity ...

Embodiment 2

[0040] In this embodiment, the user sends a control command to control the flexible display screen of the mobile terminal in Embodiment 1 to bend forward by 180°, so that the main camera (rear camera) is flipped to the front to act as a secondary camera by using the bending of the flexible display screen. Camera (front camera) to enable users to take selfies. The mechanism for realizing the bending is a liquid metal brake, and the specific working principle can be referred to Embodiment 1.

[0041] The principle of this embodiment to realize the programmable bending of the flexible display screen along the axis of 180° is: place a group of liquid metal brakes on the bending axis of the flexible display screen, and the connecting line of the non-retractable surface of the brakes is located at the bending axis of the flexible display screen. On the axis, the electrodes of the brake are connected in parallel to a programmable voltage controller. The output voltage of the voltage ...

Embodiment 3

[0052] In this embodiment, the shooting of panoramic photos is realized in the process of using the mobile terminal of Embodiment 1 to perform the operation of bending the flexible display screen by 180°. Specifically, the following can be realized:

[0053] 1. Take panoramic photos stably (automatically, stably, and at a constant speed, take 180° panoramic photos by bending the part of the bending line of the flexible display screen by 180°, both horizontal and vertical angles are acceptable).

[0054] 2. Shooting panoramic videos stably (automatically, stably, and uniformly shooting 180° panoramic videos, no need for people to hold the mobile phone to rotate the body, just hold the mobile phone, fix a posture, and bend 180° completely by the flexible display screen to shoot a panoramic video, so that the video will be more stable and more uniform).

[0055] In this embodiment, the specific process of starting the panoramic mode for shooting is as follows: the mobile terminal...

Abstract

The invention discloses a bending unit, a flexible display screen and a mobile terminal. The bending unit comprises a voltage controller and at least one bending mechanism. Each bending mechanism comprises an electrode and a cavity, wherein the cavity is filled with liquid metal, a deformable top cover for sealing the liquid metal is arranged on the top of the cavity, the cavity has one extending direction, and the two ends, in the extending direction, of the cavity are fixed. The voltage controller is used for being electrically connected with the electrodes. Voltage is exerted on the liquid metal through the electrodes so that the surface tension can be reduced. The liquid metal is used for expanding outwards when the surface tension is reduced so that the voltage can be exerted on the top cover. The top cover is used for being bent when the voltage is exerted. The novel flexible display screen is manufactured through the liquid metal, the display screen of a mobile phone can be bent, and the pioneering technical contribution is achieved.

Description

technical field [0001] The invention relates to the field of flexible display screens, in particular to a bending unit, a flexible display screen and a mobile terminal. Background technique [0002] The traditional mechanical structure used for bending is complex and bulky. Using it for bending the flexible display will cause the entire mobile terminal to be bloated, and the bending structure is nothing more than a stepping motor drive, electromagnetic force adsorption, etc. Therefore, it has become a new development direction in this field to realize the bending structure with a simple structure and special materials in a small volume. [0003] The field of display screens has now entered the era of flexible screens, and major companies have launched their own flexible screen technologies and mobile terminals. Existing ordinary display screens, such as TFT (thin film transistor display screens), are composed of backlight parts and surface glass. The materials themselves ar...
