Problems solved by technology

The display screen is useless when the screen is black, but the reflectivity is too low when it is used as a mirror. In the prior art, a layer of reflective film is coated on the back of the screen lens, which can enhance the reflection effect, but it obviously affects the reflective effect when the display screen is used for display. its through

Embodiment 1

[0050] Such as figure 1 and 2 As shown, between the screen lens 20 and the liquid crystal screen 22, a sheet-like nanomaterial suspension layer 21 is sandwiched. Specifically, a graphene sheet (between 1um and 10um in size) coated with 10nm thick silver on both sides is used here as a sheet-shaped nanomaterial, and an aqueous solvent of SDS (sodium dodecyl sulfate, a dispersion liquid) is dissolved. , SDS is to avoid the aggregation of graphene sheets. When realizing the function of the mirror surface, the bottom magnetic layer 23 provides a static magnetic field perpendicular to the surface. Under the action of this static magnetic field, the graphene sheets are arranged perpendicular to the magnetic field due to their diamagnetic properties, and are distributed horizontally parallel to the surface of the display screen, forming a reflective surface. Such as image 3A partial enlarged view of the flaky nanomaterial suspension layer 21, the nanomaterial suspension 211 is c...

Embodiment 2

[0052] Such as figure 1 and 2 As shown, the bottom magnetic layer 23 always exists in this embodiment, and the default state of the flake nanomaterial suspension layer 21 is a mirror. Like this, when mobile phone black screen, even shut off power supply, screen can be one side silver reflecting mirror, and when display screen is woken up, and voltage is applied to the upper pole plate 210 of flake nanomaterial suspension layer 21, and screen can transmit light normally again.

[0053] At this time, the need to switch outfields can be reduced. Since the influence of the electric field can be much greater than that of the magnetic field, the torsional moment ratio can exceed 10 4 , so when the terminal screen shows light transmission, the effect of the magnetic field is almost completely offset, and the flake nanomaterial can form an array distribution with good uprightness. In this embodiment, the thickness of the flake nanomaterial is about 20nm, and its surface size is 1um ...

Abstract

The present application discloses a display screen, a control method, a device and a terminal with a mirror function, which relate to the field of wireless communication systems and can be switched to a mirror for use when the screen is black. The display screen includes a screen lens, a liquid crystal screen and a nano-suspension layer, the nano-suspension layer includes an upper plate, a nano-material layer and a ground plate, and the upper plate is arranged on the screen lens and the nano-material between the layers, and the ground electrode plate is arranged between the liquid crystal screen and the nanomaterial layer. It also includes a magnetic layer, and the magnetic layer is arranged on the back of the liquid crystal screen. When receiving the turn-off trigger signal, control the magnetic layer to provide a static magnetic field perpendicular to the display screen; when receiving the turn-on trigger signal, control the upper plate to provide a voltage, or control The upper plate provides a voltage and controls the magnetic layer to provide a static magnetic field perpendicular to the display screen.

Description

technical field [0001] The invention relates to the field of wireless communication systems, in particular to a display screen with a mirror function, a control method, a device and a terminal. Background technique [0002] Mobile phones have become a necessity for people to carry with them. For beauty lovers, there are also mirrors that are essentials to carry with you. The display screen is useless when the screen is black, but the reflectivity is too low when it is used as a mirror. In the prior art, a layer of reflective film is coated on the back of the screen lens, which can enhance the reflection effect, but it obviously affects the reflective effect when the display screen is used for display. its through. Contents of the invention [0003] The invention provides a display screen with a mirror function, a control method, a device and a terminal, which can be switched to a mirror for use when the screen is black. [0004] In order to realize the foregoing inventi...
