Description

Display screen and terminal equipment

Technical Field

The application relates to the field of terminal equipment, in particular to a display screen and terminal equipment.

Background

With the popularization of intelligent terminal devices such as mobile phones, the demand of wireless charging is increasing. The requirement of wireless charging is realized, and a corresponding induction coil is needed to support energy transfer. The transfer of energy is typically achieved by inductive coupling or magnetic resonance coupling. Both of these coupling schemes require a receiver and a transmitter with sufficient windings to receive, and generally there is no isolated ground between the receiver and transmitter.

In the existing wireless charging scheme, because an isolated ground or metal is not allowed between a receiving end and a transmitting end, in the process of realizing wireless charging, the front side of the receiving end (such as the back of a mobile phone) needs to be made into a non-metal back shell.

Disclosure of Invention

The embodiment of the invention provides a display screen and a terminal device, and aims to solve the problem that a charging coil positioned at the back of the terminal device cannot be induced with a charging device to charge the terminal device due to the fact that the back of the terminal device is a metal back shell in the prior art.

In order to solve the technical problem, the invention is realized as follows:

in a first aspect, a display screen is provided, including:

a first functional layer comprising a first surface and a second surface, the first surface being a top surface of the display screen, the first functional layer being a non-conductive layer;

a second functional layer disposed on a second surface of the first functional layer; and

and the charging coil is arranged between the second functional layer and the first functional layer.

In a second aspect, a terminal device is provided, which includes the display screen of the first aspect.

In an embodiment of the invention, the display screen is made by arranging a charging coil between a non-conductive layer arranged on the user facing surface of the display screen (first surface of the first functional layer) and a second functional layer located on the back of the non-conductive layer (second surface of the first functional layer), such that, in the process of wireless charging, the magnetic induction line generated by the charging equipment passes through the front surface of the display screen and generates induction current through the coil in the display screen, because only the first functional layer (i.e. the non-conductive layer) is arranged between the charging coil and the charging device in the display screen, the charging device can induce the charging coil in the display screen to charge the terminal device through the induced current, thereby solved among the prior art because the terminal equipment back is metal dorsal scale and lead to being located the charging coil at the terminal equipment back and can't respond to with battery charging outfit with the problem that charges to terminal equipment.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to specific embodiments of the present invention and corresponding drawings. It is to be understood that the described embodiments are only some, and not all, embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

The wireless charging mode includes electromagnetic induction mode, magnetic resonance mode, electric field coupling mode, radio wave transmission mode and the like, and the electromagnetic induction principle is mostly adopted for the wireless charging of the mobile phone. The electromagnetic induction type wireless charging mode is characterized in that when current of a power supply passes through a coil (a power transmission coil of wireless charging equipment), a magnetic field is generated, and other coils (power receiving coils at mobile phone ends) which are not electrified are close to the magnetic field, so that current is generated to charge the mobile phone.

Specifically, the changing magnetic field generates a changing electric field, the changing electric field generates a changing magnetic field, the magnitude of the changing magnetic field is related to the changing rate of the changing electric field and the changing rate of the sine function is another sine function, so that electromagnetic waves can be transmitted, and the generation of the induced voltage is related to the change of the magnetic flux, so that the changing magnetic field inside the coil generates the induced voltage, thereby completing the charging process. The wireless charging of the mobile phone is to separate the primary and secondary stages of a common transformer to achieve the wireless purpose. Of course, the working frequency of wireless charging is higher, and even the iron core can be abandoned to directly transmit energy between the coils.

According to the principle of wireless charging, an isolated ground or metal is not allowed between a receiving end (terminal device) and a transmitting end (charging device and the like), so that in the process of realizing wireless charging, the front side of the receiving end (such as the back of a single-screen mobile phone) needs to be made into a non-metal back shell.

And if the mobile phone has a double-sided screen (if the double-sided screen that sets up towards opposite directions), then the back of mobile phone is not the backshell this moment, but a display screen, and this moment, because the display screen is a slice of metallic conductor in essence, like the sensor of touch-control, all is a whole slice of ITO conductor, consequently, separate between sending end and the mobile phone has a display screen (conductor), thereby can't make and realize wireless charging between mobile phone and the battery charging outfit.

To solve the above technical problem, an embodiment of the present invention provides a display screen 100, which can be applied to a terminal device, as shown in fig. 1, where the display screen 100 may include: the first functional layer 102, the first functional layer 102 includes a first surface and a second surface, the first surface is a top surface of the display screen, the first functional layer 102 is a non-conductive layer; a second functional layer 104 disposed on a second surface of the first functional layer 102; and a charging coil 106 disposed between the second functional layer 104 and the first functional layer 102.

Since the display screen 100 of the embodiment of the present invention is manufactured by arranging the charging coil 106 between the non-conductive layer disposed on the surface of the display screen facing the user (the first surface of the first functional layer 102) and the second functional layer 104 located on the back of the non-conductive layer (i.e., the second surface of the first functional layer 102), as such, during the wireless charging, the magnetic induction line generated by the charging device 200 passes through the front surface of the display screen 100 and generates induction current through the charging coil 106 inside the display screen, since there is only the first functional layer 102 (i.e. the non-conductive layer) between the charging coil 106 and the charging device in the display screen, therefore, the charging device 200 can induce a charging coil in the display screen, to charge the terminal device by the induced current, thereby solved among the prior art because the terminal equipment back is metal dorsal scale and lead to being located the charging coil at the terminal equipment back and can't respond to with battery charging outfit with the problem that charges to terminal equipment.

That is to say, arrange the charging coil in the display screen, when the user with the distance control between display screen and the battery charging outfit in presetting length, induce and produce electric current through the coil in the battery charging outfit and the charging coil in the display screen among the terminal equipment to can realize charging to terminal equipment. Of course, when the terminal device finishes charging, the wireless charging may be turned off, or when the distance between the display screen and the charging device exceeds a preset length, because the coil in the charging device and the charging coil in the display screen in the terminal device cannot generate electromagnetic induction, the induced current gradually disappears, thereby finishing the wireless charging of the terminal device. Wherein the preset length is any value within the range of 5-15 m. Generally, if the distance between the display screen and the charging device is within 9m, the magnetic field is relatively strong, and therefore, the charging effect on the terminal device is relatively good. And when exceeding about 9m, the magnetic field weakens gradually, and at this moment, the charging to terminal equipment is not stable enough, or the charging effect is relatively poor, and when exceeding 12m even surpassing 15m, the magnetic field disappears gradually, and at this moment, can't carry out wireless charging to terminal equipment.

In addition, even if the terminal device has a double-sided screen, since the charging coil 106 is disposed between the non-conductive layer and the conductive layer on the front side of the display screen, only the non-conductive layer is disposed between the charging coil in the charging device 200 and the display screen when wireless charging is implemented, so that wireless charging between the terminal device and the charging device with the double-sided screen can be implemented. Therefore, the problem that the wireless charging of the double-sided screen mobile phone in the prior art cannot be achieved can be solved.

In the above embodiment, as shown in fig. 2, the second functional layer 104 includes a TFT glass layer 202, the TFT glass layer 202 may be disposed on the second surface of the first functional layer 102, and the charging coil 106 is disposed between the TFT glass layer 202 and the first functional layer 102.

It should be understood that in fig. 2, the TFT glass layer 202 is located below the first functional layer 102 (i.e. the second functional layer 104 is disposed on the first surface of the first functional layer 102), and at this time, the charging coil 106 is disposed above the TFT glass layer 202 and below the first functional layer 102 (in order from the front surface of the display screen to the back surface of the display screen, wherein the front surface of the display screen is the surface facing the user and the back surface of the display screen is the surface opposite to the front surface), so that, when wireless charging is performed, since there is still only a non-conductive layer between the charging device 200 and the charging coil 106 in the display screen 100, wireless charging of the terminal device by the charging device 200 can be achieved.

As shown in fig. 2 and 3, the first surface of the TFT glass layer 202 includes a plurality of pixel regions 302, the plurality of pixel regions 302 are distributed in a matrix, and the charging coil 106 is spirally wound along the outer circumference of the pixel regions 302. Wherein, the charging coil 106 may be wound in a rectangular planar spiral shape along the outer circumference of the pixel region 302.

It should be understood that the TFT glass layer 202 may correspond to a TFT substrate, a circuit diagram of the TFT substrate may be as shown in fig. 4, and a matrix type thin film transistor may be formed on the TFT substrate for switching a voltage signal of a pixel electrode. The corresponding wireless charging scheme is that on the basis of the original substrate circuit, a wiring in a winding mode is added, and then the corresponding charging IC is connected to the substrate.

That is, a plurality of pixel regions 302 may be formed on the first surface of the TFT glass layer 202, and in this case, the charging coil may be wound along the outer peripheries of different pixel regions, and two terminals a and B may be led out to be connected to the charging port of the terminal device. Because the charging coil is arranged on the first surface of the TFT glass layer 202, when wireless charging is performed, there is still only a non-conductive layer between the charging device 200 and the charging coil 106 in the display screen 100, so that electromagnetic induction generated by the charging device and the charging coil in the display screen is not affected, and an induced current is generated in the charging coil and charges the terminal device through the connection ports a and B.

The charging coil is wound around the outer periphery of the pixel area 302, and the shape of the winding may be, but not limited to, a regular planar spiral (e.g., a regular planar rectangular spiral, as shown in fig. 3), or an irregular planar spiral (e.g., an irregular planar rectangular spiral, not shown in fig. 3).

As shown in fig. 5, the TFT glass layer includes a transparent conductor layer 502(ITO) and a passivation layer 504(PV), the transparent conductor layer 502 being located between the passivation layer and the first functional layer 102, wherein the charging coil 106 is disposed on one of the two sides of the transparent conductor layer 502 that is closer to the first functional layer 102.

Alternatively, transparent conductor layer 502 can be provided with a void region 506 and charging coil 106 can be embedded in void region 506 of transparent conductor layer 502.

It can be seen that the charging coil 106 is disposed on the first surface of the TFT glass layer 202, the first surface includes one of the two surfaces of the transparent conductor layer 502 closer to the first functional layer 102, and may further include a void region 506 in the passivation layer 504, so that, in the process of wireless charging, the magnetic induction line generated by the charging device 200 may directly pass through the charging coil 106 on the first surface of the second functional layer after passing through the first functional layer 102 via the front surface (i.e., the surface facing the user) of the display screen 100, so as to generate an induction current, and charge the terminal device via the generated induction current, thereby solving the problem that the charging coil on the back of the terminal device cannot induce the charging device to charge the terminal device due to the fact that the back of the terminal device is a metal back shell.

In any of the above embodiments, the first functional layer comprises, in order from the first surface to the second surface, a glass cover plate, an upper polarizer layer, an upper glass layer, and a liquid crystal layer. Wherein the charging coil is located near one side of the second functional layer 104.

As shown in fig. 6, a touch design drawing of TDDI scheme, in which black squares represent the transparent conductor layer 502 in fig. 5, and the M3 layer in fig. 5 is used to connect the a and B ports in fig. 3.

In this way, after passing through the front surface of the display screen 100 and passing through the glass cover plate, the upper polarizer layer, the upper glass layer, and the liquid crystal layer in sequence, the magnetic induction lines generated by the charging device 200 can directly pass through the charging coil 106 on the second functional layer surface layer to generate an induced current, and the terminal device is charged through the generated induced current.

In the above further embodiment, the charging coil is connected to the charging port of the terminal device, i.e. the charging coil is not connected to the flexible circuit board FPC of the terminal device. Therefore, the display screen in the embodiment of the invention only needs to arrange the charging coil between the TFT glass layer and the first functional layer, namely, the charging coil is integrated into the TFT glass layer of the display screen, so that the wireless charging of the terminal equipment by the charging equipment can be realized, and the connection with the coil is realized without adding a single Flexible Printed Circuit (FPC). Therefore, the display screen in the embodiment of the invention can reduce the development cost of the terminal equipment.

In any of the above embodiments, the number of display screens may be one or two, wherein for two display screens, the two display screens are disposed facing away from each other. Thus, because the charging coil 106 is arranged between the non-conductive layer on the front side of the display screen and the conductive layer, only the non-conductive layer is arranged between the charging coil in the charging device 200 and the display screen when wireless charging is realized, and wireless charging between the terminal device with double-sided screen and the charging device can be realized. Therefore, the problem that wireless charging cannot be achieved by a double-sided screen mobile phone with a screen arranged in a back-to-back mode in the prior art can be solved.

Therefore, the display screen of any one of the above embodiments can effectively improve the charging method, and the wireless charging process is realized by integrating the charging coil into the display screen under the condition of keeping the metal back. Even aiming at the double-sided screen, any one surface of the mobile phone can be randomly oriented to the corresponding charging plate to realize wireless charging.

The embodiment of the invention also provides terminal equipment which comprises the display screen in any one of the embodiments. Thus, in the process of wireless charging of the terminal device, the magnetic induction line generated by the charging device 200 passes through the front side of the display screen 100 and generates induction current through the charging coil 106 in the display screen, and because only the first functional layer 102 (i.e. a non-conductive layer) exists between the charging coil 106 and the charging device in the display screen, the charging device 200 can induce the charging coil in the display screen to charge the terminal device through the generated induction current, thereby solving the problem that the charging coil at the back of the terminal device cannot induce the charging coil with the charging device to charge the terminal device due to the fact that the back of the terminal device is a metal back shell in the prior art.

Therefore, compared with the terminal device with a single-sided screen, in the process of wireless charging of the terminal device of the embodiment of the invention, the magnetic induction line generated by the charging device passes through the front side of the display screen and generates induction current through the charging coil in the display screen, and because only the first functional layer (namely, a non-conductive layer) is arranged between the charging coil and the charging device in the display screen, the charging device can induce the charging coil in the display screen to charge the terminal device through the generated induction current, so that the problem that the charging coil positioned at the back of the terminal device cannot induce the charging device to charge the terminal device due to the fact that the back of the terminal device is a metal back shell in the prior art is solved.

In addition, the terminal device according to the embodiment of the present invention may include two display screens according to any one of the above embodiments, one of the display screens is disposed on the front side of the terminal device, and the other display screen is disposed on the back side of the terminal device, so that, compared with the terminal device having a dual-sided screen, the charging coil in the terminal device according to the embodiment of the present invention is disposed between the non-conductive layer and the conductive layer on the front side of the display screen, and therefore, when wireless charging is implemented, only the non-conductive layer is disposed between the charging coil in the display screen and the charging device, so that wireless charging between the terminal device having a dual-sided screen and the charging device can be implemented. Therefore, the problem that wireless charging cannot be achieved through the double-face screen terminal equipment in the prior art can be solved.
