An embodiment of the present application provides a folding display terminal, and the folding display terminal may be a product with a display interface, such as a mobile phone, a monitor, a tablet computer, and a vehicle-mounted computer. The specific form of the above-mentioned folding display terminal is not particularly limited in this embodiment of the present application.

In order to facilitate the understanding of the folding display terminal provided by the embodiment of the present application, an existing folding display terminal is described below with reference to FIG. 1 :

As shown in FIG. 1 , the folding display terminal 01 includes a flexible display screen 10 .

Among them, the flexible display screen 10 is used for displaying images. In some embodiments of the present application, the flexible display screen 10 is a multi-layer structure. The flexible display 10 includes, for example, a touch panel (TP) module, a liquid crystal display (LCD) module, and a backlight unit (BLU). Alternatively, in other embodiments of the present application, the flexible display screen 10 may be an organic light emitting diode (organic light emitting diode, OLED) display screen.

In other embodiments, the flexible display screen 10 may be an active matrix organic light emitting diode (active matrix organic light emitting diode, AMOLED) display screen.

As a self-illuminating display, AMOLED display does not need a backlight module (BLM). Therefore, when the base substrate in the AMOLED display screen is made of a flexible resin material, such as polyethylene terephthalate (polyethylene terephthalate, PET), the AMOLED display screen can have a bendable property.

In addition, as shown in FIG. 1 , the folding display terminal 01 further includes a middle frame 20 for carrying the flexible display screen 10 .

The embodiment of the present application does not limit the structure of the middle frame 20 , and the middle frame 20 includes, for example, a carrier board and a metal frame surrounding the carrier board. Electronic devices such as a printed circuit board (PCB), a camera, and a battery can be disposed on the surface of the carrier plate facing the metal back cover. Among them, the camera and battery are not shown in the figure. The metal back cover is connected with the middle frame 20 to form an accommodating cavity for accommodating the above-mentioned electronic devices such as the PCB, the camera, and the battery. Therefore, it is possible to prevent water vapor and dust from outside from invading into the accommodating cavity, thereby affecting the performance of the above-mentioned electronic device.

The flexible display screen 10 can be electrically connected to the PCB disposed on the carrier board after passing through the carrier board through a flexible printed circuit (FPC) as shown in FIG. 1 . Therefore, the PCB can transmit display data to the flexible display screen 10 to control the flexible display screen 10 to perform image display.

The flexible display screen 10 , the middle frame 20 and the metal back cover may be disposed on different layers, and these layers may be parallel to each other. The plane where each layer is located may be referred to as the X-Y plane, and the direction perpendicular to the X-Y plane may be referred to as the Z direction. That is to say, the flexible display screen 10, the middle frame 20 and the metal back cover can be distributed in layers in the Z direction.

It should be noted that the related drawings of the middle frame 20 in the present application are simplified schematic diagrams of the structure, and the middle frame 20 is not limited to the structure in the figure, and may also include other structures, which will not be repeated here.

The middle frame 20 includes a first structural member 201 , a second structural member 202 and a rotating shaft 203 located between the first structural member 201 and the second structural member 202 .

The rotating shaft 203 is connected with the first structural member 201 and the second structural member 202 . The first structural member 201 and the second structural member 202 can rotate around the rotation shaft 203 respectively. The first structural member 201 and the second structural member 202 may be a casing or a middle frame structure of an electronic device.

The first structural member 201 and the second structural member 202 can be used to carry the flexible display screen 10 , so that the flexible display screen 10 is kept as flat as possible during use, and the non-display surface of the flexible display screen 10 is protected.

A part of the flexible display screen 10 is fixed on the first structural member 201 through the adhesive layer, and a part is fixed on the second structural member 202 through the adhesive layer, and the rest of the flexible display screen 10 is located on the first structural member 201 and the second structural member 202 between. The adhesive layer may be a thin film layer formed after applying glue, and the specific form of the adhesive layer is not limited in the embodiments of the present application. In addition, the first structural member 201 and the second structural member 202 may also be provided with other electronic components, for example, a camera, an earphone, an earpiece, a button, a battery, etc. The embodiment of the present application applies to the first structural member 201 and the second structural member. Other electronic components provided on the component 202 are not limited.

The first structural member 201 and the second structural member 202 can rotate along the axis O-O of the rotating shaft 203 respectively, thereby driving the flexible display screen 10 to fold or unfold. As shown in Figures 1a, 1b and 1c, the flexible display screen 10 can be bent and flattened.

Wherein, as shown in FIG. 1a, when the included angle α between the first structural member 201 and the second structural member 202 is 180°, the flexible display screen 10 is in an unfolded state.

FIG. 1b shows a flattening process of the flexible display screen 10 from 180° to 0°, or a folding process from 0° to 180°.

Alternatively, as shown in FIG. 1 c , when the included angle α between the first structural member 201 and the second structural member 202 is 0°, the flexible display screen 10 is in a folded state.

In the case where the first structural member 201 and the second structural member 202 do not have bending properties, the area on the flexible display screen 10 connected to the first structural member 201 by the adhesive layer cannot be bent, and this part of the area is as shown in FIG. 5 . The first non-bending region 101 is shown.

The area on the flexible display screen 10 that is connected with the second structural member 202 through the adhesive layer cannot be bent under the load of the second structural member 202 , and this part of the area is the second non-bending area 102 as shown in FIG. 5 . .

In addition, in the flexible display screen 10, the part between the first non-bending area 101 and the second non-bending area 102 is the bending area 103 that enables the folding display terminal 01 to achieve bending characteristics.

Wherein, as shown in FIG. 1b and FIG. 1c, when the first structural member 201 and/or the second structural member 202 rotate around the rotation axis 203, so that the included angle α between the first structural member 201 and the second structural member 202 decreases , the flexible display screen 10 is bent accordingly, and at the same time, the flexible display screen 10 is shifted in layers during the bending process.

In some embodiments, as shown in FIG. 2 and FIG. 3 , in order to ensure the strength of the middle frame 20 and meet the requirements of the slotted antenna of the middle frame 20, the current protective structure 30 is mostly selected not to damage the structure of the traditional middle frame 20, and the middle frame 20 can be Elevate, and set the protective structure 30 on the middle frame 20 .

However, the difference d1 between the protective structure 30 elevated on the middle frame 20 and the surface of the flexible display screen 10 is relatively large. When the foldable display terminal is folded, the fingers are easily rubbed against the protective structure 30, which reduces the user experience. .

In addition, as shown in (a) and (b) of FIG. 2 , in order to ensure the overall coordination of the elevated protective structure 30, the protective structure 30 adopts a scheme of wrapping around, for example, the protective structure 30 surrounds the middle frame 20 for one week, Only disconnects at the pivot position.

In this solution, the protective structure 30 greatly occupies the area of the flexible display screen 10, which reduces the screen ratio and reduces the user experience.

Moreover, in order not to affect the circuit of the frame antenna, the protective structure 30 is mostly made of plastic material, which reduces the overall delicacy and aesthetics of the folding display terminal.

Embodiments of the present application provide an improved folding display terminal.

As shown in FIG. 4 , FIG. 5 , and FIG. 6 , the folding display terminal includes: a middle frame 20 , a flexible display screen and a protective structure 30 .

It should be noted that the middle frame 20 has a first end 20a and a second end 20b arranged oppositely and a third end 20c and a fourth end 20d arranged oppositely, and the first end 20a and the second end 20b can be folded in half .

The flexible display screen is disposed in the middle frame 20 , and the flexible display screen has a display surface and a non-display surface arranged opposite to each other, and the non-display surface is close to the middle frame 20 .

At least one end of the first end 20a of the middle frame 20 and the second end 20b of the middle frame 20 is provided with the protective structure 30, and the protective structure 30 extends from the middle frame 20 to the upper side of the display surface of the display screen. extend.

Therefore, in the present invention, the protective structure 30 only wraps the opposite side where the flexible display screen stack is dislocated when the folded display terminal is bent, releasing the area of the flexible display screen occupied by the other two sides, which can increase the screen ratio.

In some embodiments, the folding display terminal further includes: a back cover, and the middle frame 20 is located between the flexible display screen 10 and the back cover.

The embodiment of the present application does not limit the specific structure of the protection structure 30 . In some embodiments of the present application, the height of the metal frame of the first end 20a of the middle frame 20 and the second end 20b of the middle frame 20 is lower than the height of the display surface of the flexible display screen, and the protective structure 30 is connected with the metal frame. The protective structure 30 is used to wrap the flexible display screen near the first end 20a of the middle frame 20 and the position of the flexible display screen near the second end 20b of the middle frame 20 .

In some embodiments of the present application, as shown in FIG. 6 , the protective structure 30 includes: a support portion 31 connected to the metal frame of the middle frame 20 , and a protective portion 32 parallel to the display surface of the display screen , the cross section of the support portion 31 and the protection portion 32 is an L-shaped structure.

The embodiment of the present application does not limit the connection manner of the support portion 31 and the protection portion 32 . In some embodiments, the support portion 31 and the protection portion 32 are integrally formed.

In other embodiments, the support portion 31 and the protection portion 32 are formed separately and fixedly connected together. These all belong to the protection scope of the present application.

The size of the support portion 31 and the protective portion 32 is not limited in the embodiments of the present application, wherein the height of the middle frame 20 provided with the protective structure is, for example, lower than the display surface of the display screen, and the protective portion 32 is located on the display surface of the display screen. Above the surface, the support portion 31 is used to connect the protective portion 32 and the middle frame 20 .

The difference between the protective portion 32 and the surface of the flexible display screen 10 is d2. The thickness of d2 is smaller than that of d1.

In some embodiments of the present application, the surfaces of the third end and the fourth end of the middle frame 20 are, for example, higher than the display surface of the flexible screen.

The sum of the heights of the protective portion 32 and the middle frame is the same as the heights of the third end and the fourth end of the middle frame 20 , so that the surface of the protective portion 32 is the same as the height of the third end and the fourth end of the middle frame 20 . The surfaces are in the same plane, so that the edge of the middle frame 20 is flatter.

Therefore, the height of the end portion with the protective structure installed is the same as that of the middle frame without the protective structure installed, so that the gap between the folded flexible display screens can be reduced.

Of course, in other embodiments of the present application, the sum of the protective portion 32 and the high end of the middle frame can also be made smaller or greater than the heights of the third end and the fourth end of the middle frame 20 , so that the protective portion 32 The surface is slightly higher or lower than the surface of the third end and the fourth end of the middle frame 20, which all belong to the protection scope of the present application.

The embodiment of the present application does not limit the material of the protective structure. The protective structure 30 is made of metal material, and can be selected from stainless steel or aluminum alloy. It can be processed and stamped by computer numerical control machine tool (Computer Numerical Control, CNC). Among them, CNC is an automatic machine tool controlled by a program. The control system can logically process the program specified by the control code or other symbolic instructions, and decode it through the computer, so that the machine tool can perform the specified action, and the rough material can be processed into semi-finished parts by tool cutting.

Therefore, in the present invention, the protective structure 30 is made of metal material, which improves the consistency of the material compared with the plastic material. And the metal material can be formed by CNC process, which can reduce the thickness of the protective structure 30 and reduce the Z-direction distance between the protective structure 30 and the flexible display screen, that is, reduce the gap between the protective structure 30 and the flexible display screen.

The embodiment of the present application does not limit the connection structure between the protective structure 30 and the middle frame 20 . In some embodiments, the protective structure 30 and the middle frame 20 are fixed together by adhesive layer bonding.

In other embodiments, the protective structure 30 is fixedly connected with the middle frame 20 through a connector. Wherein, the connecting piece may be a bolt.

In addition, for example, an elastic member is provided between the protective portion of the protective structure 30 and the flexible display screen. The elastic member can be made of elastic material with lower hardness.

The material of the elastic member includes, but is not limited to, foam or silicone. The elastic member is, for example, fixed on the protective structure 30 , and there is no constraint between the protective structure 30 and the screen, which will not affect the dislocation of the flexible display screen stack.

Therefore, by arranging the elastic member, the flexible display screen is prevented from directly contacting the protective structure 30, and the deformation of the flexible display screen is not affected, and the flexible display screen can be better protected.

In addition, a gap can be left between the flexible display screen and the middle frame 20 to prevent the flexible display screen 10 from coming into contact with the middle frame 20 when the flexible display screen 10 is in different layers.

As shown in (a) and (b) of FIG. 7 , the folding display terminal adopts an inner folding design, and in the folded state, the flexible display screen is located inside the device.

When the folding display terminal with the inner folding design is folded, the dislocation of the flexible display screen stack is at the left and right ends of the mobile phone. Therefore, in this embodiment, the protective structure 30 can be arranged at the left and right ends of the folding display terminal.

This embodiment of the present application does not limit the structure of the folding display terminal. As shown in FIG. 7 and FIG. 9 , the folding display terminal may adopt an inner folding setting, and as shown in FIG. 8 and FIG. 10 , an outer folding design may also be adopted.

In addition, the folding display terminal may adopt a top-down folding design, or a left-right folding design. These all belong to the protection scope of the present application.

Among them, as shown in Figure 7 and Figure 8, for the folding display terminal designed to be folded up and down, the dislocation of the flexible display screen stack is at the upper and lower ends of the mobile phone. When in use, the user's palm/finger is held at the left and right ends of the middle frame. The folding display terminal designed to be folded up and down can prevent the user's palm or fingers from contacting the protective structure.

As shown in Figure 9 and Figure 10, for the foldable display terminal designed to be folded left and right, the flexible display stack is dislocated at the left and right ends of the mobile phone. When in use, the user's palm/finger is held at the left and right ends of the middle frame. Protective structure contact.

It can be understood that the positions of the first end 20a of the middle frame 20 and the second end 20b of the middle frame 20 can be exchanged. The positions of the third end 20c and the fourth end 20d may be interchanged.

The protective structure 30 includes: a first part 301 and a second part 302, the first part 301 is arranged on the first end 20a of the middle frame 20 of the middle frame 20, and the second part 302 is arranged in the middle frame 20 The second end 20b of the middle frame 20 of the frame 20.

It should be noted that, in other embodiments of the present application, the protective structure may be provided only at one end of the first end 20a of the middle frame 20 of the middle frame 20 or the second end 20b of the middle frame 20, all of which belong to the scope of protection of this application.

In the unfolded state, the distance between the protective structures 30 at the left and right ends and the surface of the flexible display screen is small, which reduces the friction between the user's palm/finger and the protective structure 30 when holding, and improves the user's feel.

When the flexible display screen is folded, the protection structure 30 can cover the dislocation of the flexible display screen, the protection structures 30 at the left and right ends are completely overlapped, and the protection structures 30 at the left and right ends are the same height as the middle frame 20 without the protection structures 30 installed at the upper and lower ends, reducing The gap between the flexible displays after folding is reduced.

It can be understood that the positions of the first end 20a of the middle frame 20 and the second end 20b of the middle frame 20 can be exchanged. The positions of the third end 20c and the fourth end 20d may be interchanged.

In the unfolded state, the user's palm/finger holds the left and right ends of the protective structure 30 to avoid contact with the protective structure 30, which improves the user's feel.

When the flexible display screen is folded, the protection structure 30 can cover the dislocation of the flexible display screen, the protection structures 30 at the upper and lower ends are completely overlapped, and the protection structures 30 at the upper and lower ends are the same height as the middle frame 20 without the protection structure 30 installed at the left and right ends, reducing The gap between the flexible displays after folding is reduced.
