Detailed Description

In order to enable those skilled in the art to better understand the technical aspects of the present utility model, the display device and the electronic apparatus provided by the present utility model are described in detail below with reference to the accompanying drawings.

An electronic device provided in the embodiments of the present application includes, but is not limited to, an electronic device with a camera, such as a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a handheld computer, an intercom, a netbook, a POS machine, a personal digital assistant (personal digital assistant, PDA), a wearable device, a virtual reality device, a wireless usb, a bluetooth sound device, a bluetooth headset, or a vehicle-mounted device.

With the technical development of electronic devices, the demands for thinning, light weight, narrow frame and high screen ratio of the display screen of the electronic device are more and more urgent. Wherein the display screen generally comprises a housing and a display module mounted within the housing. As shown in fig. 1, taking a liquid crystal display (liquid crystal display, LCD) as an example, the display Module 120a is a liquid crystal display Module (LCD Module, LCM), the display Module 120a includes a back plate 128a (back cover), a frame 129a (mold frame), a reflective sheet 121a, a light guide plate 122a (light guide plate, LGP), an optical film 123a, and a display panel 124a (panel), the back plate 128a includes a substrate 1281a and a frame 1282a connected to the peripheral edge of the substrate 1281a, the substrate 1281a and the frame 1282a enclose a cavity, the reflective sheet 121a, the light guide plate 122a, the optical film 123a, and the display panel 124a are sequentially stacked in the cavity, the reflective sheet 121a is connected to one surface of the substrate 1281a facing the cavity, and the frame 129a surrounds the reflective sheet 121a, the light guide plate 122a, and the optical film 123a and is used for supporting the display panel 124a.

The display 100a further includes a control circuit board assembly 170a, and the control circuit board assembly 170a is mounted in the housing 110a and electrically connected to the display panel 124a of the display module 120a to achieve control. Currently, there are two forms of mounting locations for the control circuit board assembly 170a within the housing 110 a.

Fig. 2 is a schematic cross-sectional view of a display module 120a provided by an example of the related art. In one example of the related art, as shown in fig. 2, the display module 120a adopts a Flat structure design, specifically, a frame 1282a of the back plate 128a is provided with a base 1284a protruding away from an outer surface of the cavity, and the control circuit board assembly 170a is mounted on the base 1284a and electrically connected to the display panel 124a through signal lines.

Fig. 3 is a schematic cross-sectional view of another display module 120a provided by an example of the related art. In another example of the related art, as shown in fig. 3, the display module 120a adopts a Bent structure design, specifically, the control circuit board assembly 170a is mounted on the surface of the substrate 1281a facing away from the cavity, the control circuit board assembly 170a is electrically connected to the display panel 124a through signal wires, and the signal wires are Bent from the side of the back plate 128a facing away from the cavity to the side of the display panel 124a facing away from the back plate 128 a.

Referring to fig. 1 to 3, the display module 120a further includes a fixing tape 1283a (cell tape), wherein the fixing tape 1283a covers an edge region of a bottom surface of the substrate 1281a, an outer surface of the frame 1282a, and an edge region of a top surface of the frame 1282a, and the display module 120a is connected to an inner surface of the housing 110a through the fixing tape 1283a, such that the display module 120a is fixed in the housing 110 a.

As can be seen from the above, the size of the display 100a is closely related to the size of the display module 120 a. In order to achieve thickness reduction, light weight, narrow frame and high screen ratio, the thickness of the display module 120a on the market is reduced to 1.4mm, and the thickness of the frame of the housing 110a is reduced to 1.4mm. On this basis, how to design the display 100a with thinner thickness, narrower frame, lighter weight and higher screen ratio is a problem to be considered.

From the above description, it can be understood that, when the display module 120a is shown in fig. 2, since the control circuit board assembly 170a is mounted on the base 1284a protruding from the frame 1282a, the width W1 of the display module 120a in the first direction (shown as L in fig. 2) is large, and thus the bezel is limited by this structure and is difficult to be further narrowed, the width between the outermost edge of the display area of the display screen 100a and the outermost edge of the bezel is difficult to be reduced, thereby resulting in difficulty in further improving the screen ratio. When the display module 120a is shown in fig. 3, since the control circuit board assembly 170a is mounted on the side of the substrate 1281a of the back plate 128a away from the cavity, the thickness of the display module 120a is large at a local position, and thus the thickness of the display 100a is limited by this structure and is difficult to be reduced. Based on this, in order to reduce the thickness and weight of the display module 120a, the display module 120a is generally manufactured with a thinner material, which results in a decrease in the strength of the display module 120 a. Thus, in some examples, when the display screen 100a further includes a cover and a glass cover, the display module 120a and the glass cover are installed in a cavity enclosed by the housing 110a and the cover, and the glass cover is located between the display panel 124a of the display module 120a and the cover, and the strength of the display module 120a is reduced, so that the edge of the glass cover is easily damaged under the extrusion action of the cover, and thus the peripheral edge of the display screen 100a is light leaked, which results in poor performance of the display screen 100 a.

In summary, in order to design a display screen with a thinner thickness, a narrower frame, a lighter weight and a higher screen ratio, on the basis that the size of the display module has been approaching a limit, it is generally easy to think of replacing the material of the display module with a thinner material, which may cause the strength of the display module to decrease, thereby affecting the performance of the display screen.

Therefore, according to the display device provided by the embodiment of the application, the back plate, the rubber frame and the fixing adhesive tape in the display module are omitted, and other parts of the display module are directly installed in the shell, so that the thickness and the width of the display module are reduced. Thus, the display device is thinned, lightened, narrow in frame and high in screen ratio while avoiding the strength reduction of the display module as much as possible.

The structure of the display device provided in the embodiments of the present application is specifically described below with reference to the drawings and specific embodiments. Some of the terms in this application are explained below to facilitate understanding by those skilled in the art.

Black edge width: refers to the width between the outermost edge of the housing of the electronic device and the outermost edge of the display area in the display device of the electronic device. The black edge width has a larger influence on the screen occupation ratio of the electronic equipment, and the smaller the black edge width is, the larger the screen occupation ratio of the electronic equipment is.

Screen ratio: the display device is used for representing the ratio of the effective display area to the whole area of the electronic equipment. On the basis of constant whole area, the larger the display area is, the larger the screen occupation ratio is, and the user experience is more beneficial.

Fig. 4 is a schematic cross-sectional view of a display device according to an embodiment of the present application. Referring to fig. 4, the display device 100 includes a housing 110 and a display module 120. The housing 110 includes a bottom plate 111 and a frame 112, the frame 112 is connected to the peripheral edge of the bottom plate 111, and the entire bottom plate 111 and the entire frame 112 together define an accommodating space 113. Of course, in other embodiments, the bottom plate 111 and a portion of the frame 112 may together define the accommodating space 113. That is, it is understood that the accommodating space 113 is defined by at least a portion of the bottom plate 111 and at least a portion of the frame 112.

The display module 120 may also be referred to as a backlight unit (BLU). The display module 120 is located in the accommodating space 113, and the display module 120 includes a reflective sheet 121, a light guide plate 122, an optical film 123 and a display panel 124 that are sequentially stacked, where one surface of the reflective sheet 121 facing away from the light guide plate 122 is fixedly connected with one surface of the bottom plate 111 facing toward the accommodating space 113, and the light guide plate 122, the optical film 123 and the display panel 124 are located on one side of the reflective sheet 121 facing away from the bottom plate 111. The display panel 124 is used for displaying images and videos.

In some embodiments, the optical film 123 may specifically include a diffusion film layer 1231, where the diffusion film layer 1231 is located on a side of the light guide plate 122 facing away from the reflective film, and the diffusion film layer 1231 can correct the light guided out by the light guide plate 122, so as to achieve the effect of optical diffusion.

In some embodiments, the optical film 123 may specifically include a first prism layer 1232 and a second prism layer 1233, where the first prism layer 1232 is located between the light guide plate 122 and the display panel 124, and the second prism layer 1233 is located between the first prism layer 1232 and the display panel 124, i.e., the second prism layer 1233 is located on a side of the first prism layer 1232 facing away from the reflective sheet 121. Of course, referring to the example shown in fig. 4, the optical film 123 may include a diffusion film layer 1231, a first prism layer 1232, and a second prism layer 1233 that are sequentially stacked, so that the light diffused by the diffusion film layer 1231 can be converged by refraction of the first prism layer 1232 and the second prism layer 1233, which is beneficial to enhancing the light-emitting brightness of the display module 120.

For example, the display panel 124 may specifically include a first polarizer 1241, an array substrate 1242, a color film substrate 1243, and a second polarizer 1244 sequentially stacked in a thickness direction (shown as Z in fig. 4) of the chassis 111, wherein the first polarizer 1241 is closer to the reflective sheet 121 than the second polarizer 1244. For example, the first polarizer 1241 may be a thin film transistor polarizer (Thin Film Transistor Polarizer, TFT POL), the array substrate 1242 may be a thin film transistor Glass plate (Thin Film Transistor Glass, TFT Glass), the color film substrate 1243 may be a color filter Glass plate (Color Filter Glass, CF Glass), and the second polarizer 1244 may be a color filter polarizer (Color Filter Polarizer, CF POL). Of course, in other embodiments of the present application, the first polarizer 1241, the array substrate 1242, the color film substrate 1243 and the second polarizer 1244 may be replaced by other ways.

In some embodiments, as shown in fig. 4, the display module 120 further includes a masking tape 125 (masking tape), the masking tape 125 is located between the optical film 123 and the display panel 124, the display panel 124 has a display area and a non-display area surrounding the display area, and the masking tape 125 is attached to a portion of the display panel 124 corresponding to the non-display area. Thus, after the light led out through the optical film 123 is blocked by the light shielding tape 125, the light emitting path is limited, so that the non-display area corresponding to the light shielding tape 125 does not display an image. Thus, the black width W2 can be understood as the width between the inner edge of the masking tape 125 and the outermost edge of the frame 112.

In this embodiment, since the display module 120 does not include the back plate, the adhesive frame and the fixing tape, the remaining components of the display module 120 (such as the reflective sheet 121, the light guide plate 122, the optical film 123 and the display panel 124) are directly mounted in the housing 110, and thus the thickness h, the weight and the width W1 of the display module 120 in the first direction (L) are reduced. Therefore, the overall thickness H and the weight of the display device 100 can be reduced without changing the thickness t of the bezel 112 and the display area of the display area, and the bezel 112 can be narrowed closer to the light guide plate 122, the optical film 123 and the display panel 124, so that the black width W2 of the display device 100 can be correspondingly reduced, and the screen ratio can be further improved.

As can be seen from the above description, in the display device 100 of the present embodiment, the back plate, the frame and the fixing tape of the display module 120 are removed, so that the rest of the components of the display module 120 are directly mounted in the housing 110 of the display device 100, and the housing 110 can directly support the display module 120. In this way, the backlight module is put into the shell (BLU In Machine, BIM), so that the thickness H, the weight and the width W1 of the display module 120 can be reduced while the strength of the display module 120 is not reduced as much as possible, which is further beneficial to reducing the thickness H, the weight and the black width W2 of the display device 100, further beneficial to further realizing thinning and light weight, and further beneficial to reducing the frame 112 and improving the screen occupation ratio.

Here, it should be noted that, through extensive data analysis by the present inventors, it is found that the thickness of the back plate 128a of the liquid crystal display module in the related art is greater than or equal to 0.2mm, the thickness of the fixing tape 1283a is greater than or equal to 0.05mm, and an assembly gap is provided between each component of the liquid crystal display module along the stacking direction, and the dimension of the assembly gap in the thickness direction of the back plate 128a is 0.15mm. In the display device 100 of the embodiment of the present application, the thickness h of the display module 120 can be reduced by at least 0.4mm because the back plate, the adhesive frame and the fixing adhesive tape are omitted from the display module 120.

In some embodiments, a foam layer 130 (front) may be further disposed between the reflective sheet 121 and the bottom plate 111 of the housing 110, and the display module 120 is stably mounted in the housing 110 through the foam layer 130. Moreover, the foam adhesive layer 130 has a compressible property, and can play a role of buffering, so as to prevent the display module 120 from being damaged due to the impact force transmitted to the display module 120 when the display device 100 collides.

Fig. 5 is a schematic structural diagram of a display device 100 when the electronic device provided in the embodiment of the present application is a notebook computer, and fig. 6 is a schematic structural diagram of the electronic device shown in fig. 5 in which the flexible circuit board 171 is mated with the control circuit board assembly 170 and the array substrate 1242. Referring to fig. 5, the display module 120 further includes a backlight source 126 installed in the accommodating space 113, wherein the backlight source 126 is specifically disposed at a side of the light guide plate 122, that is, the backlight source 126 provides light for the display module 120 in a side-entering manner, so that the display module 120 displays a picture. The display module 120 further includes a light plate 127, the light plate 127 is located at a side of the backlight source 126 facing the bottom plate 111, and the backlight source 126 is disposed on the light plate 127.

Also, the display device 100 further includes a light blocking part 140 fixedly disposed in the receiving space 113, and the light blocking part 140 surrounds the backlight light source 126 at least together with the light guide plate 122. In this way, the backlight source 126 is surrounded by the light blocking portion 140 and the light guide plate 122, so that it is beneficial to ensure that the light emitted by the backlight source 126 can be projected onto the light guide plate 122 as much as possible, reducing the light loss, and further enhancing the light emitting brightness of the display module 120.

It should be appreciated that the light blocking portion 140, at least in conjunction with the light guide plate 122, surrounding the backlight source 126 should be construed broadly and includes, but is not limited to, a variety of possible implementations:

for example, in one possible implementation, the light blocking portion 140 is a box structure with an opening formed on one side, the light guide plate 122 blocks the opening, and the backlight source 126 is located inside the box structure. In the present embodiment, the light blocking portion 140 and the light guiding plate 122 both enclose the backlight source 126, and the light emitted by the backlight source 126 is projected onto the light guiding plate 122 through the opening. The lamp plate 127 can be fixedly connected with the box body structure at this time, so that the lamp plate 127 and the backlight source 126 are effectively fixed on the light blocking portion 140.

For example, in another implementation manner, the light blocking portion 140 is a light blocking plate with a flat plate structure, the light blocking plate is disposed parallel to the bottom plate 111, the light blocking plate is fixedly connected to the inner surface of the frame 112, and two ends of the light blocking plate along the second direction respectively extend to abut against two opposite sides of the frame 112 in the second direction. The second direction is perpendicular to the first direction (L) and the thickness direction (Z) of the bottom plate 111. In this embodiment, the light blocking plate, a portion of the inner surface of the bezel 112, a portion of the bottom plate 111, and the light guide plate 122 together enclose the backlight light source 126. The light plate 127 can be fixedly connected with the surface of the bottom plate 111 facing the accommodating space 113, so that the light plate 127 and the backlight source 126 are effectively fixed on the bottom plate 111.

For example, in still another possible implementation manner, the light blocking portion 140 may be an "L" shaped plate structure, where one of the arms of the "L" shaped plate structure is disposed parallel to the bottom plate 111 and has a certain distance in the Z direction from the bottom plate 111, the other arm of the "L" shaped plate structure abuts against the bottom plate 111, and two ends of the "L" shaped plate structure along the second direction extend to abut against two sides opposite to the frame 112 in the second direction, respectively. In this embodiment, the backlight source 126 is surrounded by the "L" -shaped plate structure, the portion of the bottom plate 111, the portions of the opposite sides of the frame 112 in the second direction, and the light guide plate 122. The light plate 127 can be fixedly connected with the surface of the bottom plate 111 facing the accommodating space 113, so that the light plate 127 and the backlight source 126 are effectively fixed on the bottom plate 111.

For example, in still another possible implementation manner, as shown in fig. 5, the light blocking portion 140 includes a first plate 141, a second plate 142, and an intermediate plate 143 vertically connected to the first plate 141 and the second plate 142, where the first plate 141 and the second plate 142 are located on the same side of the intermediate plate 143 and are parallel to a surface of the bottom plate 111 facing the accommodating space 113, the first plate 141 is fixedly connected to a surface of the bottom plate 111 facing the accommodating space 113, and two ends of the first plate 141, the second plate 142, and the intermediate plate 143 along the second direction respectively extend to abut against two surfaces of the frame 112 opposite to each other in the second direction. That is, the light blocking portion 140 has a "U" shape. In this embodiment, the backlight source 126 is surrounded by the first plate 141, the second plate 142, the middle plate 143, the portions of the two opposite sides of the frame 112 in the second direction, and the light guide plate 122. The lamp plate 127 can be fixedly connected with the surface of the first plate 141 facing the second plate 142, so that the lamp plate 127 and the backlight source 126 are effectively fixed on the first plate 141.

Thus, in the embodiment in which the light blocking portion 140 includes the first plate body 141, the second plate body 142, and the intermediate plate body 143, the light blocking portion 140 is fixedly mounted in the accommodating space 113 by assembling and connecting the first plate body 141 with the bottom plate 111, and the mounting operation of the light blocking portion 140 is simpler and facilitates the improvement of the assembly efficiency, compared to the light blocking portion 140 having a flat plate structure, the flat plate structure being assembled and connected with the inner surface of the frame 112, and the light blocking portion 140 having an "L" shaped plate structure, the "L" shaped plate structure being assembled and connected with the bottom plate 111.

The fixing connection manner between the first plate 141 and the bottom plate 111 is not limited to bonding or clamping, and the first plate 141 and the bottom plate 111 may be screwed by a screw (for example, a screw).

The light blocking portion 140 may be made of, for example, aluminum, copper, stainless steel, or the like, and is not particularly limited in this embodiment. In the embodiment in which the light blocking portion 140 includes the first plate body 141, the second plate body 142, and the intermediate plate body 143, the "U" -shaped light blocking portion 140 may be formed by bending using a punching process, or may be formed by machining.

Along the thickness direction (Z) of the bottom plate 111, a distance D between a surface of the first plate body 141 facing the second plate body 142 and a surface of the second plate body 142 facing the first plate body 141 should be greater than or equal to a sum of a thickness of the lamp panel 127 along the Z direction and a thickness of the backlight light source 126 along the Z direction. Illustratively, D may range from 3.5mm to 6.5mm.

It is also noted that, based on the above description, the lamp panel 127 may be fixedly disposed on the light blocking portion 140 or the bottom plate 111 according to the difference in the structure of the light blocking portion 140. In this way, the lamp plate 127 and the backlight source 126 can be effectively fixed, so that the installation stability of the backlight source 126 is increased, and the display device 100 is beneficial to avoiding abnormal display images caused by the position deviation of the backlight source 126 in the reliability test or normal use process.

Further alternatively, the backlight source 126 and the light guide plate 122 may be disposed in the same layer with a gap between the backlight source 126 and the light guide plate 122, on the basis of the embodiment in which the light blocking portion 140 includes the first plate body 141, the second plate body 142, and the intermediate plate body 143. Here, referring to fig. 5, it can be understood that the same-layer arrangement means that the backlight source 126 and the light guide plate 122 are arranged side by side, and the backlight source 126 is arranged at the side of the light guide plate 122, so that it is beneficial to ensure that as much light emitted by the backlight source 126 is guided into the light guide plate 122 as possible.

The lamp panel 127 and the reflecting sheet 121 are arranged in the same layer. In fig. 5, the lamp panel 127 is arranged side by side with the reflecting sheet 121, and the lamp panel 127 is disposed at a side portion of the reflecting sheet 121. The orthographic projection of the light plate 127 on the base plate 111 coincides with the orthographic projection of the light guide plate 122 on the base plate 111. That is, the lamp plate 127 is positioned at a side of the backlight source 126 facing the bottom plate 111 and seals a gap between the backlight source 126 and the light guide plate 122.

In addition, the display module 120 further includes a reflective adhesive layer 150, where the reflective adhesive layer 150 is located on a side of the backlight source 126 and the light guide plate 122 facing away from the bottom plate 111, the reflective adhesive layer 150 is fixedly connected to a surface of the second plate 142 facing the first plate 141, and an orthographic projection of the reflective adhesive layer 150 on the bottom plate 111 covers a portion of the orthographic projection of the light guide plate 122 on the bottom plate 111, and at least a portion of the orthographic projection of the backlight source 126 on the bottom plate 111. In other words, the reflective adhesive layer 150 is located on the side of the backlight source 126 away from the bottom plate 111 and seals the gap between the backlight source 126 and the light guide plate 122.

Through the above arrangement, the lamp panel 127 and the reflective adhesive layer 150 can block the light emitted by the backlight source 126 from leaking from the gap, i.e. reduce the possibility of light leakage at the gap. Furthermore, the reflective adhesive layer 150 can reflect the light in the gap into the light guide plate 122. Thus, the light loss is reduced, the light-emitting brightness of the display module 120 is enhanced, and the quality of the display picture is improved.

There are various possibilities for the positional relationship between the reflective adhesive layer 150 and the second plate 142. In some embodiments, the reflective adhesive layer 150 may be located in a space enclosed by the light blocking portion 140 and the light guide plate 122. Alternatively, as shown in fig. 5, an end of the reflective adhesive layer 150 away from the middle plate 143 may protrude from an end of the second plate 142 away from the middle plate 143, that is, the second plate 142 does not cover the entire reflective adhesive layer 150, and a portion of the reflective adhesive layer 150 extends beyond the second plate 142.

There are various possibilities for the positional relationship between the light guide plate 122 and the second plate body 142. In some embodiments, as shown in fig. 5, an end surface of the second plate body 142 remote from the end of the middle plate body 143 may be flush with an end surface of the light guide plate 122 near the backlight source 126. Alternatively, in some embodiments, the orthographic projection of the light guide plate 122 on the bottom plate 111 coincides with the orthographic projection of the second plate body 142 on the bottom plate 111, that is, the portion of the edge of the light guide plate 122 extends between the second plate body 142 and the bottom plate 111.

There are various possibilities for the positional relationship of the first plate 141 and the second plate 142. In some embodiments, as shown in fig. 5, an end surface of the first plate 141 at an end remote from the intermediate plate 143 may be flush with an end surface of the second plate 142 at an end remote from the intermediate plate 143. Alternatively, the end of the second plate 142 remote from the intermediate plate 143 is further remote from the intermediate plate 143 than the end of the first plate 141 remote from the intermediate plate 143.

With continued reference to fig. 4 and 5, the display device 100 further includes a transparent protective cover 160, the transparent protective cover 160 is located on the light emitting side of the display panel 124, and the transparent protective cover 160 is fixedly connected to the display panel 124. And, the frame 112 is formed with a step having a step plane and a step side, the step plane is parallel to the bottom plate 111, and the transparent protective cover 160 is overlapped on the step plane and fixedly connected with the frame 112. The side of the transparent protective cover 160 facing away from the display panel 124 is a front surface, and the front surface is exposed to the external environment.

Thus, images and videos displayed on the display panel 124 can be displayed through the transparent protective cover 160, and the transparent protective cover 160 can protect the display panel 124. The transparent protective Cover 160 may be, for example, a Glass Cover Glass (CG).

It should be understood that the transparent protective cover 160 and the frame 112 may be fixedly connected by adhesive bonding, or may be connected by other connecting methods such as clamping. The transparent protective cover 160 may be specifically bonded to the stepped plane of the bezel 112. Alternatively, the transparent protective cover 160 may be bonded to the step side of the bezel 112. In some embodiments, the transparent protective cover 160 may also be bonded to both the step plane and the step side of the bezel 112.

In order to further improve the installation stability of the transparent protective cover 160, an optical adhesive 161 (Optically Clear Adhesive, OCA) may be further disposed between the transparent protective cover 160 and the display panel 124, and the transparent protective cover 160 and the display panel 124 are adhesively connected by the optical adhesive 161.

As an alternative embodiment, the display device 100 further includes a control circuit board assembly 170 (printed circuit board assembly, PCBA), where the control circuit board assembly 170 is electrically connected to the display panel 124 of the display module 120, so as to control the display module 120.

The display device 100 may further include a communication antenna electrically connected to the control circuit board assembly 170 through a cable 180 (cable), the communication antenna being configured to transmit and receive signals, the cable 180 being routed between the display module 120 and the base plate 111. Specifically, for example, as shown in fig. 4, when the display device 100 further includes the foam adhesive layer 130, the foam adhesive layer 130 is provided with an avoidance groove, a recess is formed on a surface of the bottom plate 111 facing the accommodating space 113, the recess corresponds to the avoidance groove and is communicated with the avoidance groove for the cable 180 to extend, a part of the cable 180 is located in the recess, and the rest part is located in the avoidance groove.

In an application scenario of the present application, the electronic device is a mobile phone or a tablet computer. In this embodiment, the entire bottom plate 111 and the entire frame 112 together define the accommodating space 113. In this application scenario, the control circuit board assembly 170 is installed in the accommodating space 113, and the installation manner of the control circuit board assembly 170 may refer to fig. 2 or fig. 3.

It should be understood that, for the mobile phone or tablet computer provided with the display device 100 according to the embodiment of the present application, even if the control circuit board assembly 170 of the display device 100 is installed in the accommodating space 113 in the manner shown in fig. 2 or 3, the thickness h, the weight and the width W1 in the first direction (L) of the display module 120 of the mobile phone or tablet computer of the present embodiment are reduced due to the omission of the back plate, the adhesive frame and the fixing adhesive tape, and the display module 120 can further achieve the thinning, the light weight, the narrow frame and the high screen ratio.

In another application scenario of the present application, the electronic device is a notebook computer. In this embodiment, as shown in fig. 5, the electronic device further includes a host, and the housing 110 of the display apparatus 100 is rotatably connected to the host through a Hinge 190 (Hinge). The following describes in detail the installation of the control circuit board assembly 170 in the application scenario in which the electronic device is a notebook computer with reference to the accompanying drawings.

Fig. 7 is a schematic structural diagram of another display device 100 when the electronic apparatus provided in the embodiment of the present application is a notebook computer. In this embodiment, as shown in fig. 5 and 7, a portion of the bottom plate 111 and a portion of the frame 112 together enclose an accommodating space 113. Specifically, a separation bump 115 is convexly arranged on the bottom plate 111, and the separation bump 115 is fixedly connected with the inner surface of the frame 112; the rim 112 includes first and second associated walls. The partition protrusion 115, the first portion of the bottom plate 111, and the first surrounding wall together define the accommodating space 113, the partition protrusion 115, the second portion of the bottom plate 111, and the second surrounding wall together define the mounting groove 114, and the rotation shaft 190 is rotatably disposed in the mounting groove 114.

In this way, the display module 120 and the rotating shaft 190 are respectively installed in the accommodating space 113 and the installation groove 114, and the accommodating space 113 and the installation groove 114 are separated by the separation bump 115, so that the display module 120 is prevented from being damaged due to the interference between the rotation of the rotating shaft 190 and the display module 120.

In this embodiment, when the display device 100 further includes the transparent protective cover 160, the transparent protective cover 160 is further overlapped on the separation bump 115, and the transparent protective cover 160 can be fixedly connected with the separation bump 115. Here, it should be noted that, there is no overlapping portion between the front projection of the transparent protective cover 160 on the bottom plate 111 and the front projection of the mounting groove 114 on the bottom plate 111, that is, the transparent protective cover 160 is not connected to the entire frame 112, so as to avoid interference between the transparent protective cover 160 and the rotating shaft 190.

The display device 100 may further include a cover 191 covering the frame 112 and the partition protrusion 115 to close the mounting groove 114 together with the partition protrusion 115, the second portion of the bottom plate 111, and the second surrounding wall so that the rotation shaft 190 is not exposed to the outside, improving the aesthetic appearance of the display device 100.

In a specific example of the present application, as shown in fig. 7, the control circuit board assembly 170 is fixedly disposed on a side of the partition protrusion 115 facing away from the bottom plate 111, and the control circuit board assembly 170 is located between the mounting groove 114 and the receiving space 113. Further alternatively, a receiving groove may be formed in a surface of the separation bump 115 facing away from the bottom plate 111, and the control circuit board assembly 170 is mounted in the receiving groove, so that a surface of the control circuit board assembly 170 facing away from the bottom plate 111 may be flush with the light emitting surface of the display panel 124.

In the display device 100 of the notebook computer of the present embodiment, although the control circuit board assembly 170 also occupies a certain size in the first direction (L) as compared with the display screen having the display module 120a shown in fig. 2, since the back plate, the frame and the fixing tape of the display module 120 are removed, the rest of the components of the display module 120 are directly mounted into the housing 110 of the display device 100, so that the thickness H, the weight and the width W1 of the display module 120 can be reduced while the strength of the display module 120 is not reduced as much as possible, thereby being beneficial to reducing the thickness H, the weight and the black width W2 of the display device 100, so that the thickness, the weight, the narrow frame and the high screen ratio can be further realized.

In another specific example of the present application, as shown in fig. 5, the control circuit board assembly 170 is fixedly disposed in the mounting groove 114, and the control circuit board assembly 170 is perpendicular to the bottom plate 111.

In the display device 100 of the notebook computer of the embodiment, the back plate, the adhesive frame and the fixing adhesive tape of the display module 120 are removed, so that the thickness H, the weight and the width W1 of the display module 120 can be reduced, and the thickness H, the weight and the black width W2 of the display device 100 can be reduced. Further, by mounting the control circuit board assembly 170 into the mounting groove 114, the control circuit board assembly 170 does not occupy a space of the display device 100 in the thickness direction as compared with the display screen having the display module 120a shown in fig. 3, which is advantageous in further reducing the thickness H of the display device 100, and thus further thinning can be achieved. In addition, such a design is also advantageous in improving the space utilization of the mounting groove 114.

The fixing connection manner of the control circuit board assembly 170 and the bottom plate 111 is not limited to bonding or clamping, and the control circuit board assembly 170 and the bottom plate 111 may be further screwed by a screw (for example, a screw) so as to be fixed in the mounting groove 114.

In the embodiment in which the control circuit board assembly 170 is fixedly disposed in the mounting groove 114, the control circuit board assembly 170 may be electrically connected to the display panel 124 through the flexible circuit board 171 (Flexible Printed Circuit, FPC), and the separation bump 115 is formed with a relief slit 1151 through which the flexible circuit board 171 passes. Since the display device 100 realizing the thin, light weight, narrow bezel and high screen ratio has a small internal space, the flexible circuit board 171 is highly flexible and limited by the space size by designing the flexible circuit board 171.

Referring to fig. 6, in the technical solution of the display panel 124 including the first polarizer 1241, the array substrate 1242, the color film substrate 1243 and the second polarizer 1244, one end of the flexible circuit board 171 is connected to the control circuit board assembly 170, and the other end passes through the avoiding slit 1151 to be lapped to a surface of the array substrate 1242 of the display panel 124 facing away from the bottom plate 111, so as to connect the control circuit board assembly 170 to the array substrate 1242.

In an embodiment in which the display device 100 of the notebook computer includes the transparent protective cover 160, as an implementation manner, the display device 100 may further include a cover (not shown), where the cover is connected to the frame 112 of the housing 110 to cover the accommodating space 113, and the transparent protective cover 160 is located between the display module 120 and the cover. In this embodiment, the housing 110 may also be referred to as an a-shell (ACover), and the Cover may also be referred to as a B-shell (B Cover).

It is to be understood that the above embodiments are merely illustrative of the application of the principles of the present utility model, but not in limitation thereof. Various modifications and improvements may be made by those skilled in the art without departing from the spirit and substance of the utility model, and are also considered to be within the scope of the utility model.
