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, in this embodiment, the bottom magnetic layer 23 always exists, 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 application discloses a display screen with a mirror function, a control method, a control apparatus and a terminal, and relates to the wireless communication system field. The display screen with the mirror function can be used as a mirror during a black screen. The display screen includes a screen lens, a liquid crystal screen, and a nanometer suspension layer. The nanometer suspension layer includes an upper polar plate, a nanometer material layer and a grounding polar plate. The upper polar plate is arranged between the screen lens and the nanometer material layer. The grounding polar plate is arranged between the liquid crystal screen and the nanometer material layer. The display screen also includes a magnetic layer arranged at the back of the liquid crystal screen. When a closure trigger signal is received, the magnetic layer is controlled to provide a static magnetic field perpendicular to the display screen. The control apparatus is used for controlling the upper polar plate to provide the voltage when a turn-on trigger signal is received, or controlling the upper polar plate to provide a voltage and controlling the magnetic layer to provided the 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...
