Description

Technical Field

[0001] The present application relates to the technical field of display screens, and in particular to a liquid crystal display screen and an electronic device. Background Art

[0002] Liquid crystal displays (LCDs), as display components in electronic devices, are widely used in a variety of electronic products. LCDs primarily consist of a front frame, a display module, and a back cover. The display module is mounted within the back cover, while the front frame surrounds the display module and is connected to the back cover. Currently, LCDs have relatively wide front frames, resulting in a small display area, which fails to meet consumer demand for high screen-to-body ratios. Utility Model Content

[0003] The embodiments of the present application provide a liquid crystal display and an electronic device, aiming to increase the screen-to-body ratio of the liquid crystal display.

[0004] In a first aspect, an embodiment of the present application provides a liquid crystal display screen, comprising:

[0005] A housing and a display panel, a backlight module and a control module arranged in a cavity of the housing;

[0006] The display panel is used to form a display image, the backlight module is used to provide light source to the display panel, and the control module is used to control the display panel to form the image;

[0007] The backlight module and the display panel are arranged along a first direction, and the projection area of the display panel is larger than the projection area of the backlight module; along a second direction, the control module is connected to one side of the display panel;

[0008] The first direction is perpendicular to the second direction.

[0009] In the embodiments of the present application, by increasing the area of the display panel and placing it on the outermost side of the LCD screen, the LCD screen can achieve a full-screen display without the need for a cover plate. This provides a wider viewing experience, enhancing visual effects and aesthetics. Furthermore, while achieving a full-screen display, the LCD screen is further made thinner and lighter.

[0010] Furthermore, in the embodiment of the present application, the control module is disposed on one side of the display panel, leaving assembly space on one side of the backlight module to facilitate the installation of other components.

[0011] In one possible design, the control module includes a conversion chip, a flexible circuit board, and a driver chip;

[0012] Along the first direction, the conversion chip is electrically connected to the display panel and is disposed on a side of the display panel away from the backlight module;

[0013] Along the first direction, the driving chip is arranged on a side of the display panel close to the backlight module;

[0014] The driver chip is electrically connected to the conversion chip via the flexible circuit board. In an embodiment of the present application, the display panel includes an array substrate, a liquid crystal layer, and a filter layer stacked along a first direction. The array substrate is disposed on a side of the liquid crystal layer close to the backlight module, and the filter layer and the array substrate are located on both sides of the liquid crystal layer. The conversion chip can be disposed on the array substrate and electrically connected to the circuit of the array substrate. The flexible circuit board can be bent, and the driver chip is connected to the driver chip via the flexible circuit board. The driver chip is mounted on the driver circuit board, and the driver circuit board and the driver chip are disposed on one side of the backlight module along a second direction.

[0015] The filter layer includes a plurality of color filters, and the display panel includes a plurality of pixels, and the plurality of pixels generally include a red sub-pixel (R), a green sub-pixel (G) and a blue sub-pixel (B), and each sub-pixel has a corresponding color filter. The array substrate is provided with a thin film transistor array, and each sub-pixel is equipped with a thin film transistor. The control module is connected to the circuit on the array substrate, and the control module includes a conversion chip, a flexible circuit board, a driver chip, and a driver circuit board. Among them, the display signal can be input from the host to the driver chip, and the driver chip converts the display signal into an input signal that can be recognized by the conversion chip. The conversion chip receives the input signal of the driver chip and transmits the input signal to the circuit of the array substrate, thereby controlling the arrangement of the liquid crystal molecules in the liquid crystal layer through the thin film transistor, controlling the intensity of the transmitted white light, and forming various colors in combination with the color filter to realize display.

[0016] In a possible design, the control module further includes a support member, one end of the support member is connected to the display panel, and the other end extends out of the display panel along the second direction, and the driving chip is arranged on the portion of the support member extending out of the display panel.

[0017] In an embodiment of the present application, the support member supports the control module. When the support member is connected to the display panel, part of the structure of the support member protrudes from the display panel along the second direction, and the driving chip is arranged on the part of the structure of the support member protruding from the display panel, so as to realize that the driving chip is arranged on one side of the display panel along the second direction.

[0018] In a possible design, along the first direction, the display panel and the backlight module are bonded by a first adhesive, and along the circumference of the liquid crystal display screen, the first adhesive is disposed at an edge of the backlight module.

[0019] In the embodiment of the present application, a first adhesive is provided between the display panel and the backlight module along a first direction to pre-fix the display panel and the backlight module. Along the circumference of the liquid crystal display screen, the first adhesive is at the outermost edge of the backlight module, reducing the area occupied by the first adhesive on the backlight module.

[0020] In one possible design, the display panel has a display area and a non-display area located outside the display area;

[0021] A side of the non-display area close to the backlight module is connected to an outer peripheral side of the backlight module via a second adhesive, and the second adhesive is arranged to avoid the control module.

[0022] In the embodiment of the present application, after the first adhesive is bonded, a second adhesive is applied on the side of the non-display area of the display panel close to the backlight module and on the outer periphery of the backlight module to further fix the display panel and the backlight module.

[0023] In the embodiment of the present application, the second adhesive is disposed in the non-display area of the display panel and the side of the backlight module, thereby reducing the area occupied by the second adhesive on the display panel and the backlight module.

[0024] In a possible design, optical adhesive is provided between the display panel and the backlight module, and the optical adhesive completely covers the surface of the backlight module close to the display panel.

[0025] In the embodiment of the present application, the display panel and the backlight module are connected by optical glue. The optical glue is colorless and transparent, and forms a uniform and stable adhesion layer on the surface of the backlight module, meeting the optical path design requirements between the backlight module and the display panel.

[0026] Because the backlight module provides light for the display panel, the optical adhesive must completely cover the surface of the backlight module near the display panel to prevent the different refractive indices of the light emitted by the backlight module from affecting the display effect. At the same time, it also ensures the stability of the connection between the display panel and the backlight module.

[0027] In a possible design, the backlight module and the housing are bonded together by a third adhesive.

[0028] In the embodiment of the present application, when the display panel and the backlight module are assembled to the housing, the backlight module is bonded and fixed to the inner bottom wall of the housing by a third adhesive to fix the position of the backlight module.

[0029] In one possible design, the liquid crystal display further includes a sealing member;

[0030] The sealing member includes a sealing portion, which is arranged between the display panel and the housing along the circumference of the liquid crystal display screen;

[0031] Wherein, the sealing portion is arranged to avoid the control module.

[0032] In the embodiment of the present application, a sealing member is disposed between the display panel and the housing along the circumference of the liquid crystal display screen to block the gap between the display panel and the housing.

[0033] In a possible design, the sealing member further includes a shielding portion, wherein the shielding portion is connected to the sealing portion;

[0034] Along the first direction, the shielding portion covers the housing;

[0035] Wherein, the shielding portion is arranged to avoid the control module.

[0036] In the embodiment of the present application, the cross-section of the sealing member is L-shaped. Along the first direction, the shielding portion is located above the housing and completely covers the housing. From the appearance of the LCD screen, the sealing member and the housing are integrated, without excessive decoration, and are more simple.

[0037] In a second aspect, an embodiment of the present application provides a liquid crystal display screen, comprising:

[0038] Display panel;

[0039] a backlight module, wherein the backlight module and the display panel are arranged along a first direction;

[0040] A control module is electrically connected to the display panel; the control module includes a driving circuit board and a driving chip arranged on the driving circuit board, and along the first direction, the driving circuit board and the driving chip are arranged on a side of the display panel close to the backlight module.

[0041] In the embodiment of the present application, the display panel is positioned at the outermost edge of the LCD screen, allowing the LCD screen to achieve a full screen without the need for a cover. Simultaneously, the control module's driver circuit board and driver chip are positioned on the side of the backlight module away from the display panel. From a subjective perspective, only the display panel and a small portion of the backlight module are visible. This reduces the width of the LCD screen's lower bezel, which must cover the control module, and increases the screen-to-body ratio, broadening the display field of view and enhancing user viewing comfort.

[0042] In a possible design, along the first direction, the driver circuit board and the driver chip are located between the backlight module and the display panel, and the projection of the display panel along the first direction covers the driver circuit board and the driver chip.

[0043] In an embodiment of the present application, the driver circuit board and the driver chip are arranged on a side of the display panel close to the backlight module, and along the second direction, the driver circuit board and the driver chip do not extend beyond the display panel. At this time, the driver chip and the driver circuit board do not occupy the space of the liquid crystal display along the second direction, reducing the width of the lower frame of the liquid crystal display that needs to cover the control module, thereby increasing the screen-to-body ratio of the liquid crystal display.

[0044] In a possible design, along the second direction, one end of the driver chip and the driver circuit board extends out of the display panel, and the other end is connected to the display panel, so that the driver chip and the backlight module are distributed along the second direction.

[0045] In an embodiment of the present application, in order to avoid the position of the control module, the driver circuit board and the driver chip of the control module extend out of the display panel along the second direction. However, since the driver circuit board and the driver chip are located on the side of the display panel facing the backlight module along the first direction, the embodiment of the present application not only improves the screen-to-body ratio of the LCD display, but also reduces the thickness of the LCD display, thereby improving the lightness and thinness of the LCD display and enhancing the portability of the electronic device.

[0046] In one possible design, the control module further includes a support member;

[0047] Along the second direction, one end of the support member extends out of the display panel, and the other end is connected to the driving circuit board and the driving chip.

[0048] In the embodiment of the present application, the driver chip is supported by a supporting member and is prominently displayed on the panel, so as to ensure that the driver chip is stably arranged.

[0049] In a possible design, a dimension of the driving circuit board along the second direction is L, and a dimension of the driving circuit board extending beyond the display panel along the second direction is L1, satisfying the following: 0.4≤L1 / L≤0.8.

[0050] In the embodiments of the present application, L1 / L can specifically be 0.4, 0.5, 0.6, 0.7, 0.8, etc.

[0051] If the value of L1 / L is too large (e.g., greater than 0.8), the driver circuit board extends longer from the display panel in the second direction, requiring a wider lower frame to cover the driver circuit board, reducing the screen-to-body ratio of the LCD. If the value of L1 / L is too small (e.g., less than 0.4), the driver circuit board extends shorter from the display panel in the second direction, and the driver circuit board extends longer between the display panel and the backlight module in the first direction, preventing the driver circuit board and the backlight module from being distributed in the second direction. This increases the thickness of the LCD.

[0052] In one possible design, the liquid crystal display screen includes a housing having a cavity;

[0053] The backlight module and the display panel are both arranged in the cavity;

[0054] The backlight module is installed on the housing, and / or the backlight module is installed on the display panel.

[0055] In the embodiment of the present application, part of the structure of the driver circuit board extends out of the display panel along the second direction, avoiding the position of the backlight module, so that the backlight module can be bonded and fixed to the display panel, thereby further reducing the thickness of the liquid crystal display screen. Alternatively, the backlight module can also be disconnected from the display panel and mounted on the housing. In this case, part of the structure of the driver circuit board extends out of the display panel along the second direction, so that the backlight module can be closer to the display panel, which can also reduce the distance between the display panel and the backlight module. Whether the backlight module is connected or not connected to the display panel can be determined according to actual conditions and is not limited here.

[0056] In a possible design, the display panel and the backlight module are bonded together by a first adhesive, and the first adhesive is disposed at an edge of the backlight module along a circumference of the liquid crystal display screen.

[0057] In the embodiment of the present application, a first adhesive is provided between the display panel and the backlight module along a first direction to pre-fix the display panel and the backlight module. Along the circumference of the liquid crystal display screen, the first adhesive is at the outermost edge of the backlight module, reducing the area occupied by the first adhesive on the backlight module.

[0058] In one possible design, the display panel has a display area and a non-display area located outside the display area;

[0059] The non-display area is bonded to the periphery of the backlight module via a second adhesive, and the second adhesive is arranged to avoid the control module.

[0060] In the embodiment of the present application, the display area is the area of the LCD display that displays an image, and the non-display area is the area of the LCD display that does not display an image. After the first adhesive is applied, a second adhesive is applied to the non-display area of the display panel near the backlight module and on the outer periphery of the backlight module to further secure the display panel to the backlight module.

[0061] In the embodiment of the present application, the second adhesive is disposed in the non-display area of the display panel and the side of the backlight module, thereby reducing the area occupied by the second adhesive on the display panel and the backlight module.

[0062] In a possible design, optical adhesive is provided between the display panel and the backlight module, and the optical adhesive completely covers the surface of the backlight module close to the display panel.

[0063] In the embodiment of the present application, the display panel and the backlight module are connected by optical glue. The optical glue is colorless and transparent, and forms a uniform and stable adhesion layer on the surface of the backlight module, meeting the optical path design requirements between the backlight module and the display panel.

[0064] Because the backlight module provides light for the display panel, the optical adhesive must completely cover the surface of the backlight module near the display panel to prevent the different refractive indices of the light emitted by the backlight module from affecting the display effect. At the same time, it also ensures the stability of the connection between the display panel and the backlight module.

[0065] In a possible design, the backlight module and the housing are bonded together by a third adhesive.

[0066] In the embodiment of the present application, when the display panel and the backlight module are assembled to the housing, the backlight module is bonded and fixed to the inner bottom wall of the housing by a third adhesive to fix the position of the backlight module.

[0067] In one possible design, the liquid crystal display further includes a sealing member;

[0068] The sealing member includes a sealing portion and a shielding portion. Along the circumference of the liquid crystal display screen, the sealing portion is arranged between the display panel and the housing; along the first direction, the shielding portion covers the side wall of the housing.

[0069] In the embodiments of the present application, a sealing member is disposed between the display panel and the housing along the circumference of the LCD screen to block the gap between them. The sealing member has an L-shaped cross-section. Along a first direction, the blocking portion is located above the housing and completely covers it. From the outside, the LCD screen appears to be integrated with the housing, lacking excessive decoration and maintaining a more concise appearance.

[0070] In a possible design, the shell includes a lower frame, and along the first direction, the lower frame covers the control module.

[0071] In the embodiment of the present application, the lower frame can shield the drive circuit board, drive chip and other structures of the control module to prevent the control module from being exposed.

[0072] In a third aspect, an embodiment of the present application provides an electronic device, the electronic device comprising:

[0073] keyboard;

[0074] A liquid crystal display screen, wherein the liquid crystal display screen is the liquid crystal display screen described above;

[0075] The liquid crystal display screen is electrically connected to the keyboard.

[0076] In the embodiments of the present application, the electronic device may be a laptop or a desktop computer. Taking a laptop as an example, the electronic device includes at least a liquid crystal display, a keyboard, and a host computer (in an all-in-one desktop computer, the host computer is integrated into the liquid crystal display). The liquid crystal display may be rotatably connected to the keyboard via a hinge structure or a rotating shaft structure, and the host computer is mounted inside the keyboard, with both the keyboard and the liquid crystal display being electrically connected to the host computer.

[0077] Liquid crystal displays (LCDs) convert image signals from electronic devices into visual images and display them on the screen for users to view and use. For example, users can view emails, documents, pictures, videos, etc. on the display.

[0078] The LCD screen contains a control module responsible for receiving and processing image sources. The control module is used to connect the mainboard in the host and the display panel in the LCD screen.

[0079] The embodiments of the present application not only increase the screen-to-body ratio of the liquid crystal display, but also reduce the thickness of the liquid crystal display, thereby improving the lightness and thinness of the liquid crystal display and enhancing the portability of the electronic device.

The conversion chip 113a is electrically connected to the display panel 111, enabling signal transmission between the conversion chip 113a and the display panel 111. That is, the display signal can be input from the host 13 to the driver chip 113c, the driver chip 113c converts the display signal into an input signal that can be recognized by the conversion chip 113a, the conversion chip 113a receives the input signal of the driver chip 113c, and transmits the input signal to the circuit of the display panel 111, controlling the display panel 111 to form a display screen.

[0111] like Figure 3 FIG. 1 is a side view schematic diagram of a liquid crystal display screen structure in one embodiment. The liquid crystal display screen 11 includes a display panel 111, a backlight module 112, and a control module 113. The display panel 111 is used to form a display image. The backlight module 112 is the light source of the liquid crystal display screen 111, and the light it emits can illuminate the display panel 111. The control module 113 is used to control the display panel 111 to form an image.

[0112] Along the first direction Z, the backlight module 112 is disposed behind the display screen of the display panel 111 . Along the second direction X, some components of the control module 113 are connected to one side of the backlight module 112 , and the control module 113 is electrically connected to the display panel 111 .

[0113] Specifically, the display panel 111 includes an array substrate 111a, a liquid crystal layer 111b, and a filter layer 111c stacked along a first direction Z.

The filter layer 111c includes multiple color filters. The display panel 111 includes multiple pixels, which typically include red sub-pixels (R), green sub-pixels (G), and blue sub-pixels (B), each of which has a corresponding color filter. The array substrate 111a is provided with a thin film transistor array, and each sub-pixel is equipped with a thin film transistor.

The control module 113 includes a conversion chip 113a, a flexible circuit board 113b, a driver chip 113c, and a driver circuit board 113d. Among them, the display signal can be input from the host to the driver chip 113c, and the driver chip 113c converts the display signal into an input signal that can be recognized by the conversion chip 113a. The conversion chip 113a receives the input signal of the driver chip 113c and transmits the input signal to the circuit of the array substrate 111a, thereby controlling the arrangement of the liquid crystal molecules in the liquid crystal layer 111b through the thin film transistor, controlling the intensity of the transmitted white light, and combining with the color filter to form various colors to achieve display.

[0114] More specifically, the conversion chip 113a can be disposed on the array substrate 111a and electrically connected to the circuitry of the array substrate 111a. The flexible circuit board 113b is bendable, and the driver chip 113c is connected to the driver chip 113c via the flexible circuit board 113b. The driver chip 113c is mounted on a driver circuit board 113d.

Specifically, one end of the support member 11a is connected to the backlight module 112, and the other end extends out of the backlight module 112 along the second direction X. This connects the driver circuit board 113d to the portion of the support member 11a extending out of the backlight module 112, thereby connecting the control module 113 to one side of the backlight module 112 in the second direction X. The support member 11a is used to support the driver circuit board 113d and the driver chip 113c, allowing them to be positioned on one side of the backlight module 112 in the second direction X.

[0116] In some embodiments, the support member 11a can be a backlight iron frame, an iron sheet, or the like.

[0117] Please continue to refer to Figure 4 , Figure 4This is a cross-sectional view of a portion of the structure of a liquid crystal display in another embodiment. The liquid crystal display 11 includes a display panel 111, a backlight module 112, a control module 113, and a support member 11a. The display panel 111 is used to display an image, the backlight module 112 is the light source for the liquid crystal display 111, and the light it emits illuminates the display panel 111. The control module 113 is used to control the display panel 111 to form an image.

[0118] Specifically, the display panel 111 includes an array substrate 111a, a liquid crystal layer 111b, and a filter layer 111c stacked along a first direction Z. The array substrate 111a is disposed on the side of the liquid crystal layer 111b closest to the backlight module 112, while the filter layer 111c and the array substrate 111a are located on either side of the liquid crystal layer 111b. The control module 113 includes a conversion chip 113a, a flexible circuit board 113b, a driver chip 113c, and a driver circuit board 113d. The signal transmission between these components can be found above and will not be further elaborated here.

[0119] More specifically, the rotating chip 113a can be disposed on the array substrate 111a and electrically connected to the circuitry of the array substrate 111a. The driver chip 113c is connected to the driver chip 113c via the flexible circuit board 113b. The driver chip 113c is mounted on a driver circuit board 113d. The driver circuit board 113d and the driver chip 113c are disposed on one side of the array substrate 111a along the second direction X.

[0120] Please continue to refer to Figure 4 The driver circuit board 113d is connected to the array substrate 111a via the support member 11a. Specifically, one end of the support member 11a is connected to the array substrate 111a, and the other end extends out of the array substrate 111a along the second direction X. This connects the driver circuit board 113d to the portion of the support member 11a extending out of the array substrate 111a, thereby connecting the driver chip 113c and the driver circuit board 113d in the control module 113 to one side of the array substrate 111a in the second direction X. The support member 11a is used to support the driver circuit board 113d and the driver chip 113c, so that the driver circuit board 113d and the driver chip 113c can be disposed on one side of the array substrate 111a in the second direction X.

[0121] In this embodiment, the driver circuit board 113d and the driver chip 113c are disposed on one side of the display panel 111 along the second direction X. That is, the projection of the driver circuit board 113d and the driver chip 113c along the second direction X does not overlap with the projection of the backlight module 112 along the second direction X. Therefore, the driver circuit board 113d and the driver chip 113c are absent from the one side of the backlight module 112 along the second direction X. This leaves assembly space on the one side of the backlight module 112 along the second direction X to facilitate the installation of other components.

[0122] like Figure 5 Shown Figure 3 and Figure 4 The front view of the LCD screen 11 is a schematic diagram of the structure of the LCD screen. The LCD screen 11 includes a display panel 111 and a control module 113. The control module 113 is disposed on one side of the display panel 111 along the second direction X, specifically on the side of the display panel 111 near the keyboard. The LCD screen 11 also includes a lower frame 114c (the dotted line in the figure indicates the location of the lower frame) for covering the control module 113. The lower frame 114c is connected to the housing of the LCD screen 11 (not shown in the figure) and is located on the side of the display panel 111 near the keyboard.

[0123] Depend on Figure 3 、 Figure 4 and Figure 5 As can be seen in the illustrated embodiment, since some components of the control module 113 are disposed on one side of the backlight module 112 along the second direction X, the display panel 111 cannot cover the control module 113. Therefore, the width of the lower frame 114c needs to be increased to cover the control module 113 and prevent the control module 113 from being exposed. As a result, the width of the lower frame 114c of the LCD screen 11 is increased, occupying space on the display panel. This prevents the LCD screen 11 from achieving a satisfactory screen-to-body ratio, thus affecting the user's viewing field.

[0124] To address this technical problem, this embodiment provides an electronic device, including but not limited to a laptop computer or desktop computer. For ease of illustration, this embodiment uses a laptop computer as an example. The following describes in detail possible structures of liquid crystal displays in electronic devices, with reference to the accompanying drawings.

[0125] like Figure 6 The figure shows a side view of a portion of the structure of a liquid crystal display screen in one embodiment. The liquid crystal display screen 11 includes a display panel 111, a backlight module 112, and a control module 113. Along a first direction Z, the backlight module 112 is disposed on the back side of the display panel 111. The control module 113 is electrically connected to the display panel 111, and a portion of the control module 113 is disposed on the side of the backlight module 112 away from the display panel 111.

[0126] For details, please refer to Figure 6The display panel 111 includes a stacked array substrate 111a, a liquid crystal layer 111b, and a filter layer 111c. The array substrate 111a is located on the side of the liquid crystal layer 111b closest to the backlight module 112, while the filter layer 111c and the array substrate 111a are located on either side of the liquid crystal layer 111b. The control module 113 includes a conversion chip 113a, a flexible circuit board 113b, a driver chip 113c, and a driver circuit board 113d. The signal transmission between these components can be found above and will not be further elaborated here.

[0127] More specifically, the conversion chip 113a can be disposed on the array substrate 111a and electrically connected to the circuitry of the array substrate 111a. The flexible circuit board 113b is bendable, and the driver chip 113c is connected to the driver chip 113c via the flexible circuit board 113b. The driver chip 113c is mounted on the driver circuit board 113d, which is mounted on the side of the backlight module 112 away from the display panel 111. Specifically, the driver chip 113c is located on the side of the driver circuit board 113d away from the backlight module 112. The conversion chip 113a, the driver circuit board 113d, and the driver chip 113c are arranged along the first direction Z, and the projection of the backlight module 112 along the first direction Z can cover the projection of the driver circuit board 113d and the driver chip 113c along the first direction Z. In this case, the driver circuit board 113d and the driver chip 113c do not occupy space on the liquid crystal display screen 11 along the second direction X.

[0128] Figure 7 Shown Figure 6 The main view of the LCD screen in FIG. 1 is a schematic diagram showing the LCD screen 11 including a display panel 111, a flexible circuit board 113b of a control module, and a lower frame 114c for covering the control module (the dotted line in the figure indicates the position of the lower frame). Figure 6Part of the structure of the control module 113 (the driver chip 113c and the driver circuit board 113d) is arranged on a side of the backlight module 112 away from the display panel 111. The driver circuit board 113d and the driver chip 113c do not occupy the space of the liquid crystal display screen 11 along the second direction X. Therefore, from the main viewing direction of the liquid crystal display screen 111 (the perspective of a user using the electronic device), only the display panel 111 and a portion of the flexible circuit board 113b occupy the space of the liquid crystal display screen 11 along the second direction X. Compared with the arrangement of the driver circuit board 113d and the driver chip 113c along the second direction X with the display panel 111, the arrangement of the driver circuit board 113d and the driver chip 113c in this embodiment can reduce the space occupied by the control module 113 on the liquid crystal display screen 11 along the second direction X, reduce the width of the lower frame 114c of the liquid crystal display screen 11 that needs to cover the control module, thereby increasing the screen-to-body ratio of the liquid crystal display screen 11, improving the display field of view, and enhancing user viewing comfort. At the same time, in this embodiment, the driving circuit board 113d is connected to the side of the backlight module 112 away from the display panel 111. The backlight module 112 can support the driving circuit board 113d, so there is no need to set up additional supporting members to support the driving circuit board 113d, thereby simplifying the structure.

[0129] In this embodiment, the assembly process of the liquid crystal display screen 11 is as follows: first, the display panel 111 is connected to the backlight module 112, and then the control module 113 is connected to the display panel 111 and the backlight module 112 respectively. Specifically, the conversion chip 113a of the control module 113 is connected to the array substrate 111a of the display panel 111, and the driving circuit board 113d of the control module 113 is connected to the backlight module 112. Finally, the display panel 111, the backlight module 112, and the control module 113 are installed together in the housing.

[0130] Depend on Figure 6 As can be seen, in this embodiment, the driver circuit board 113d and driver chip 113c of the control module 113 are mounted on the side of the backlight module 112 away from the array substrate 111a, and the conversion chip 113a of the control module 113 is mounted on the side of the array substrate 111a away from the backlight module 112. When the flexible circuit board 113b connects the driver chip 113c and the conversion chip 113a, it occupies the side end of the backlight module 112 and the array substrate 111a along the second direction X. When the backlight module 112 needs to be connected to other components, the flexible circuit board 113b at the side end interferes with it. Moreover, the flexible circuit board 113b occupies the side end space of the backlight module 112 along the second direction X, affecting the layout of other components.

[0131] like Figure 8The side view of the partial structure of the liquid crystal display screen in another embodiment is shown. The liquid crystal display screen 11 includes a display panel 111, a backlight module 112 and a control module 113. Figure 6 The embodiment shown is different in that the display panel 111 and the control module 113 are arranged along the first direction Z and are not connected therebetween. The driving circuit board 113 d and the driving chip 113 c are connected to the side of the display panel 111 facing the control module 113 .

[0132] For details, please refer to Figure 8 The display panel 111 includes a stacked array substrate 111a, a liquid crystal layer 111b, and a filter layer 111c. The array substrate 111a is positioned on the side of the liquid crystal layer 111b closest to the backlight module 112, while the filter layer 111c and the array substrate 111a are located on either side of the liquid crystal layer 111b. The control module 113 includes a conversion chip 113a, a flexible printed circuit board 113b, a driver chip 113c, and a driver circuit board 113d. The signal transmission between these components can be found above and will not be further elaborated here.

[0133] More specifically, the conversion chip 113a can be disposed on the array substrate 111a and electrically connected to the circuitry of the array substrate 111a. The flexible circuit board 113b is bendable, and the driver chip 113c is connected to the driver chip 113c via the flexible circuit board 113b. The driver chip 113c is mounted on the driver circuit board 113d, which is mounted on the side of the array substrate 111a away from the liquid crystal layer 111b. In other words, the driver chip 113c is located on the side of the driver circuit board 113d away from the array substrate 111a, and the projection of the array substrate 111a along the first direction Z can cover the projections of the driver circuit board 113d and the driver chip 113c along the first direction Z. In this case, the driver circuit board 113d and the driver chip 113c do not occupy space on the liquid crystal display screen 11 along the second direction X.

[0134] Figure 8 The main view of the LCD screen can be referred to Figure 7Part of the structure of the control module 113 (the driver chip 113c and the driver circuit board 113d) is arranged on a side of the array substrate 111a away from the liquid crystal layer 111b. The driver circuit board 113d and the driver chip 113c do not occupy the space of the liquid crystal display screen 11 along the second direction X. Therefore, from the main viewing direction of the liquid crystal display screen 11 (the perspective of a user using the electronic device), only the display panel 111 and a portion of the flexible circuit board 113b occupy the space of the liquid crystal display screen 11 along the second direction X. Compared with the arrangement of the driver circuit board 113d and the driver chip 113c along the second direction X with the display panel 111, the arrangement of the driver circuit board 113d and the driver chip 113c in this embodiment can reduce the space occupied by the control module 113 on the liquid crystal display screen 11 along the second direction X, reduce the width of the lower frame 114c of the liquid crystal display screen 11 that needs to cover the control module, thereby increasing the screen-to-body ratio of the liquid crystal display screen 11, improving the display field of view, and enhancing user viewing comfort.

[0135] Meanwhile, in this embodiment, the driving circuit board 113d is connected to the side of the array substrate 111a away from the liquid crystal layer 111b. The array substrate 111a can support the driving circuit board 113d, so there is no need to set up additional support members to support the driving circuit board 113d.

[0136] Furthermore, in this embodiment, the driver circuit board 113d and the driver chip 113c are connected to the side of the array substrate 111a away from the liquid crystal layer 111b, and the conversion chip 113a is connected to the side of the array substrate 111a closer to the liquid crystal layer 111b. Therefore, when the flexible circuit board 113b connects the conversion chip 113a and the driver chip 113c, it only needs to occupy the side end of the array substrate 111a along the second direction X, and does not occupy the side end space of the backlight module 112. This makes the backlight module 112 suitable for connection with other components in a variety of situations. Furthermore, the side end of the backlight module 112 along the second direction X has a larger space, which can accommodate more other components.

[0137] In this embodiment, since part of the control module 113 (the driver circuit board 113d and the driver chip 113c) is connected to the back of the display panel 111 displaying the image, there is a gap between the display panel 111 and the backlight module 112 to avoid the control module 113, and there is no direct connection between the two. The assembly process of the liquid crystal display screen 11 in this embodiment is as follows: first, the control module 113 is installed on the display panel 111. Specifically, the conversion chip 113a of the control module 113 is connected to the side of the array substrate 111a of the display panel 111 close to the liquid crystal layer 111b, and the driver circuit board 113d of the control module 113 is connected to the side of the array substrate 111a away from the liquid crystal layer 111b. Then, the backlight module 112 and the display panel 111 are respectively installed in the housing.

[0138] Please continue to refer to Figure 9 , Figure 9 FIG. 1 is a side view schematic diagram of a partial structure of a liquid crystal display screen in another embodiment, wherein the display panel and the backlight module are in a disconnected state. Figure 9 The illustrated embodiment can reduce the width of the lower border of the liquid crystal display and increase the screen-to-body ratio of the liquid crystal display while also reducing the thickness of the liquid crystal display.

[0139] For details, please refer to Figure 9 The liquid crystal display screen 11 includes a display panel 111, a backlight module 112 and a control module 113. Figure 8 The difference from the illustrated embodiment is that a portion of the structure of the driving circuit board 113d in the control module 113 extends out of the display panel 111 along the second direction X, and another portion of the structure is located on the side of the display panel facing the backlight module 112, so that the driving circuit board 113d and the driving chip 113c of the control module 113 are away from the backlight module 112 along the second direction X to avoid the connection position between the backlight module 112 and the display panel 111, thereby reducing the distance between the backlight module 112 and the display panel 111, thereby improving the screen-to-body ratio of the liquid crystal display screen 11 while reducing the thickness of the liquid crystal display screen 11.

[0140] exist Figure 9 In the illustrated embodiment, the flexible circuit board 113b only occupies the side ends of the array substrate 111a along the second direction X when connecting to the conversion chip 113a and the driver chip 113c, without occupying the side end space of the backlight module 112. This allows the backlight module 112 to be connected to other components in a variety of situations. Furthermore, the side ends of the backlight module 112 along the second direction X have sufficient space for arranging other components.

[0141] Along the first direction Z, the liquid crystal display screen 11 may further include a support member 11a. A portion of the support member 11a extends from the display panel 111 along the second direction X, and another portion of the support member 11a is located between the display panel 111 and the driver circuit board 113d along the first direction Z. Along the first direction Z, one end of the support member 11a is connected to the display panel 111, and the other end is connected to the driver circuit board 113d. This allows the driver circuit board 113d and driver chip 113c of the control module 113 to be connected to the display panel 111 via the support member 11a, thereby improving the connection reliability between the control module 113 and the display panel 111.

[0142] In some embodiments, the outer edge of the support member 11a along the second direction X may be flush with the driving circuit board 113d. Figure 9As shown, the outer edge of the support member 11a along the second direction X can be located inside the outer edge of the driving circuit board 113d along the second direction X. In other words, the support member 11a does not extend beyond the driving circuit board 113d along the second direction X, thereby preventing the support member 11a from extending beyond the driving circuit board 113d along the second direction X and occupying the size of the liquid crystal display screen 11 along the second direction X.

[0143] Specifically, the display panel 111 includes an array substrate 111a, a liquid crystal layer 111b, and a filter layer 111c stacked along a first direction Z. The array substrate 111a is located on the side of the liquid crystal layer 111b closest to the backlight module 112, while the filter layer 111c and the array substrate 111a are located on either side of the liquid crystal layer 111b. The control module 113 includes a conversion chip 113a, a flexible circuit board 113b, a driver chip 113c, and a driver circuit board 113d. The signal transmission between these components can be found above and will not be further elaborated here.

[0144] More specifically, the support member 11a is connected to the array substrate 111a, and a portion of the support member 11a extends beyond the array substrate 111a in the second direction X. The conversion chip 113a can be disposed on the array substrate 111a and electrically connected to the circuitry of the array substrate 111a. The flexible circuit board 113b is bendable, and the driver chip 113c is connected to the driver chip 113c via the flexible circuit board 113b. The driver chip 113c is mounted on a driver circuit board 113d, which is mounted on the support member 11a. This allows the driver chip 113c and a portion of the driver circuit board 113d to extend beyond the array substrate 111a in the second direction X. Specifically, the driver circuit board 113d and the driver chip 113c are connected to the side of the support member 11a facing away from the array substrate 111a, and the projection of the array substrate 111a in the first direction Z partially overlaps with the projection of the driver circuit board 113d and the driver chip 113c in the first direction Z. At this time, a portion of the driving circuit board 113 d and the driving chip 113 c occupies the space along the second direction X of the liquid crystal display screen 11 .

[0145] Figure 9 In the illustrated embodiment, the backlight module 112 and the display panel 111 may be unconnected, that is, the backlight module 112 and the display panel 111 are separately installed in the housing of the electronic device. In some embodiments, the backlight module 112 may be installed on the bottom wall of the housing, and the display panel 111 may be installed on the support portion of the side wall of the housing.

[0146] Furthermore, if Figure 10 Shown Figure 9Schematic diagram of the display panel and the backlight module after being connected. In this embodiment, the driving circuit board 113d is partially moved along the second direction X so that the driving circuit board 113d extends out of the display panel 111 along the second direction X, thereby avoiding the connection position between the backlight module 112 and the array substrate 111a, so that the backlight module 112 is connected to the array substrate 111a. After the connection, the driving circuit board 113d of the control module 113 and the backlight module 112 are distributed along the second direction X. That is, Figure 10 It can be seen that in this embodiment, the backlight module 112 is connected to the display panel 111, and the driving circuit board 113d and the driving chip 113c of the control module 113 are installed on the back of the display panel 111 displaying the screen, so that the driving circuit board 113d and the driving chip 113c of the control module 113 utilize the thickness space of the backlight module 112, thereby achieving the reduction of the overall thickness of the liquid crystal display screen 11.

[0147] In addition, by Figure 10 As can be seen, to avoid the connection position between the display panel 111 and the backlight module 112, the driver circuit board 113d of the control module 113 extends beyond the array substrate 111a along the second direction X. However, because the driver circuit board 113d and the driver chip 13c are located on the side of the display panel 111 facing the backlight module 112 along the first direction X, this embodiment also reduces the proportion of the control module 113 in the width direction of the liquid crystal display screen 11 compared to when the driver circuit board 113d and the driver chip 113c are located on the side of the display panel 111 along the second direction X. Therefore, this embodiment not only improves the screen-to-body ratio of the liquid crystal display screen 11, but also reduces the thickness of the liquid crystal display screen 11, thereby improving the lightness and thinness of the liquid crystal display screen 11 and enhancing the portability of the electronic device.

[0148] Figure 10 In the embodiment shown, the driving circuit board 113d is connected to the display panel 111 via the support member 11a. In some embodiments, the support member 11a and the backlight module 112 are distributed along the second direction X (not shown in the figure), that is, the backlight module 112 and the display panel 111 are connected along the first direction Z.

[0149] In other embodiments, Figure 10As shown, along the first direction, one end of the support member 11a is connected to the display panel 111, and the other end is connected to both the driving circuit board 113d and the backlight module 112, that is, the backlight module 112 and the display panel 111 are connected through the support member 11a. In this embodiment, there is a gap 112a between the backlight module 112 and the display panel 111. The gap 112a can reduce the damage caused by the direct contact and mutual pressure between the display panel 111 and the backlight module 112, as well as reduce the risk of affecting the light output rate of the backlight module 112 and light leakage of the display panel 111. In addition, the backlight module 112 and the display panel 111 are adhesively connected, and an adhesive is placed between the two, and the adhesive can be filled in the gap 112a.

[0150] In this embodiment, the assembly process of the liquid crystal display screen 11 is as follows: first, the support member 11a is installed on the display panel 111, the control module 113 is installed on the display panel 111 through the support member 11a, and then the backlight module 112 is connected to the display panel 111. Finally, the display panel 111, the backlight module 112 and the control module 113 are installed together in the shell.

[0151] In some embodiments, as Figure 10 As shown, the dimension of the driving circuit board 113 d of the control module 113 along the second direction X is L, and the dimension of the driving circuit board 113 d extending beyond the display panel 111 along the second direction X is L1 , which satisfies the following: 0.4≤L1 / L≤0.8.

[0152] For example, L1 / L can be specifically 0.4, 0.5, 0.6, 0.7, 0.8, etc.

[0153] In this embodiment, when 0.4≤L1 / L≤0.8, the length of the driver circuit board 113d extending from the display panel 111 along the second direction X is moderate, which does not cause the width of the lower frame 114c covering the driver circuit board 113d to be too large, nor does it cause the driver circuit board 113d to interfere with the backlight module 112 along the first direction Z. As a result, the driver circuit board 113d and the driver chip 113c are distributed along the second direction X with the backlight module 112, thereby increasing the screen-to-body ratio of the liquid crystal display 11 and reducing the thickness of the liquid crystal display.

[0154] The following will describe in detail possible assembly structures of the liquid crystal display screen with reference to the accompanying drawings.

[0155] like Figure 11The figure shows a cross-sectional view of a portion of the structure of a liquid crystal display screen assembled in one embodiment. The liquid crystal display screen 11 includes a display panel 111, a backlight module 112, a housing 114, and a frame 115. The housing 114 is provided with a cavity 114a, within which the display panel 111 and the backlight module 112 are mounted. The backlight module 112 is bonded to the inner bottom wall of the housing 114. Along a first direction Z, the frame 115 is connected to the housing 114, and the frame 115 can cover the assembly gap 114b between the display panel 111 and the inner side wall of the housing 114.

[0156] In this embodiment, the LCD screen 11 is not provided with a cover plate, so that the LCD screen 11 is thin and light. However, from the appearance of the LCD screen 11, the LCD screen 11 is provided with a frame 115 around it (see FIG. Figure 1 ), affecting the user's visual experience.

[0157] like Figure 12 The figure shows a cross-sectional assembly view of a portion of a liquid crystal display screen in another embodiment. The liquid crystal display screen 11 includes a display panel 111, a backlight module 112, a housing 114, and a cover plate 116. The housing 114 is provided with a cavity 114a, within which the display panel 111 and the backlight module 112 are mounted. The backlight module 112 is bonded to the inner bottom wall of the housing 114. The cover plate 116 is connected to the side of the display panel 111 facing away from the backlight module 112. Along a first direction Z, the projection of the cover plate 116 covers the housing 114.

[0158] In this embodiment, the cover plate 116 is located at the outermost side of the LCD screen 11, which realizes a full-screen structure of the LCD screen 11 from the subjective perspective of the LCD screen 11. However, the cover plate 116 also increases the thickness and weight of the LCD screen 11, which is not conducive to achieving a thin and lightweight LCD screen 11.

[0159] For this, please refer to Figure 13 , Figure 13 The figure shows a cross-sectional view of the assembly of a portion of a liquid crystal display screen in another embodiment. The liquid crystal display screen 11 includes a display panel 111, a backlight module 112, and a housing 114. The housing 114 is provided with a cavity 114a, in which the display panel 111 and the backlight module 112 are mounted. The display panel 111 is located at the outermost side of the backlight module 112, and along the first direction Z, the projected area of the display panel 111 is larger than the projected area of the backlight module 112, so that the display panel 111 can cover the circuit structure within the cavity 114a.

[0160] In this embodiment, the display panel 111 is increased in area and disposed at the outermost side of the LCD screen 11 , eliminating the need for a cover plate and a frame, thereby enhancing the full-screen integration of the LCD screen 11 and making the LCD screen 11 thinner and lighter.

[0161] For further information, please refer to Figure 13 In order to achieve a tight fit between the display panel 111 and the inner wall of the housing 114, the liquid crystal display screen 11 may further include a seal 117, which seals the gap between the display panel 111 and the inner wall of the housing 114 to prevent external dust from entering the interior of the liquid crystal display screen 11 through the gap and causing damage to the internal structure.

[0162] Please continue to refer to Figure 13 When the display panel 111 and the backlight module 112 are directly connected, the two are connected through the first adhesive 11b and the second adhesive 11c.

[0163] Specifically, along the circumference of the liquid crystal display screen 11, the first adhesive 11b is located at the outermost edge of the backlight module 112 to reduce the first adhesive 11b's obstruction of the light source emitted by the backlight module 112. The display panel 111 has a display area and a non-display area 111d (indicated by dot-dashed lines in the figure). The display area refers to the area where the image is displayed, and the non-display area 111d refers to the area where no image is displayed. The second adhesive 11c is disposed in the space formed by the non-display area 111d and the periphery of the backlight module 112 to reduce the occupation of the second adhesive 11c on the display panel 111 and the backlight module 112, thereby expanding the display area of the liquid crystal display screen 11.

[0164] Among them, the bonding process of the display panel 111 and the backlight module 112 is: first, a first adhesive 11b is placed between the display panel 111 and the backlight module 112 to achieve pre-fixation of the two, and then a second adhesive 11c is placed in the non-display area 111d and the outer peripheral side of the backlight module 112 to further strengthen the connection between the display panel 111 and the backlight module 112.

[0165] In addition, the first adhesive 11b can form a smaller gap between the display panel 111 and the backlight module 112 to reduce the risk of damage caused by mutual compression between the display panel 111 and the backlight module 112, affecting the light output rate of the backlight module 112 and causing light leakage from the display panel 111.

[0166] Figure 13 In the illustrated embodiment, when the display panel 111 and the backlight module 112 are mounted on the housing 114 , the backlight module 112 is bonded and fixed to the inner bottom wall of the housing 114 by means of the third adhesive 11 d .

[0167] It should be noted that the first adhesive 11b and the third adhesive 11d can be solid adhesives, and the second adhesive 11c needs to be liquid adhesive. The first adhesive 11b, the second adhesive 11c and the third adhesive 11d can be adhesives commonly used in electronic devices, and this embodiment does not limit this.

[0168] It should also be noted that when placing the second adhesive 11c, the pre-fixed display panel 111 and the backlight module 112 need to be tilted so that the second adhesive 11c fills the corner groove formed by the sides of the two and solidifies, and the second adhesive 11c is filled in the periphery of the display panel 111 and the backlight module 112 in turn.

[0169] In another specific embodiment, the display panel and the backlight module may also be indirectly connected. Figure 14 FIG. 1 is a schematic diagram showing the connection between the display panel 111 and the backlight module 112 in a specific embodiment. In this embodiment, the display panel 111 and the backlight module 112 can also be bonded together by an edge tape 11g. Figure 14 As can be seen, the edge tape 11g covers the edges of the display panel 111 and the backlight module 112. This bonding method also causes the edge of the display panel 111 on the side where the image is displayed to be partially covered with the edge tape 11g, and other components are required to cover the edge tape 11g, which is not conducive to enhancing the full-screen integration of the LCD display 11.

[0170] Please refer to Figure 15 , Figure 15 for Figure 13 In the enlarged diagram of section A in the center, the cross-section of the seal 117 is roughly L-shaped. The seal 117 comprises a sealing portion 117a and a shielding portion 117b. The seal 117a is compressed between the display panel 111 and the inner wall of the housing 114, while the shielding portion 117b extends above the housing 114 along the first direction Z and completely covers the housing 114. From the outside, the seal 117 and the housing 114 appear to be integral and single components, simplifying the appearance of the LCD 11.

[0171] It should be noted that, since the control module is arranged on the side of the display panel 111 close to the keyboard, the flexible circuit board, driving circuit board, driving chip and other structures of the control module may protrude from the display panel along the second direction X. Figure 16 ,like Figure 16 The electronic equipment shown is based on Figure 13 In the schematic diagram of the liquid crystal display screen, the shell is provided with a lower frame 114c, which can cover the flexible circuit board, driving circuit board, driving chip and other structures of the control module to prevent the control module from being exposed.

[0172] It should also be noted that, please refer to Figure 15 and Figure 16 The side of the display panel 111 close to the keyboard 12 is the lower frame 114c, and the sealing member 117 is matched with the lower frame 114c along one side of its circumference.

[0173] like Figure 17 FIG. 1 is a schematic diagram of another embodiment of directly connecting the display panel 111 and the backlight module 112. Figure 13 Unlike the illustrated embodiment, the display panel 111 and the backlight module 112 can be bonded together using optical adhesive 11e. The optical adhesive 11e is colorless and transparent, forming a uniform and stable adhesive layer on the surface of the backlight module 112. This adhesive also satisfies the optical path design requirements between the backlight module 112 and the display panel 111, further expanding the display area of the LCD screen 11.

[0174] It should be noted that because the backlight module 112 provides light for the display panel 111, the optical adhesive 11e must completely cover the entire surface of the backlight module 112 near the display panel 111 to prevent the different refractive indices of the light emitted by the backlight module 112 from affecting the display effect. At the same time, it also ensures the stability of the connection between the display panel 111 and the backlight module 112.

[0175] In addition, the optical adhesive 11e can also form a smaller distance between the display panel 111 and the backlight module 112, thereby reducing the risk of damage caused by mutual squeezing after the display panel 111 and the backlight module 112 directly contact each other, affecting the light output rate of the backlight module 112 and causing light leakage in the display panel 111.

[0176] When the display panel and backlight module are not connected, the assembly structure of the two and the housing can refer to Figure 18 , Figure 18 This is a cross-sectional view of the assembly of a liquid crystal display screen in one embodiment. The liquid crystal display screen 11 includes a display panel 111, a backlight module 112, a shell 114, and a seal 117. The shell 114 is provided with a cavity 114a and a support portion 114d, and the support portion 114d protrudes inward along the inner side wall of the shell 114. The display panel 111 and the backlight module 112 are installed in the cavity 114a, and there is a gap between the backlight module 112 and the display panel 111 to avoid the control module. Specifically, the backlight module 112 is bonded to the inner bottom wall of the shell 114, and the display panel 111 is set on the support portion 114d and is bonded and fixed to the support portion 114d by a fourth adhesive 11f. The seal 117 seals the assembly gap between the display panel 111 and the inner side wall of the shell 114.

[0177] It should be noted that, in the above embodiments, Figure 3 、 Figure 4 、 Figure 6 、 Figure 8 、 Figure 9 、 Figure 10 The embodiments shown can all be used as Figure 11 Assembly shown. Figure 3 、 Figure 4 、 Figure 6 、 Figure 8 、 Figure 9 、 Figure 10 The embodiments shown can all be used as Figure 12 Assembly shown. Figure 3 、 Figure 4 、 Figure 6 、 Figure 10 The embodiments shown can all be used as Figure 13 Assemble as shown. Figure 3 、 Figure 4 、 Figure 6 、 Figure 10 The embodiments shown can all be used as Figure 17 Assemble as shown. Figure 8 、 Figure 9 The embodiments shown can all be used as Figure 18 Assemble as shown.

[0178] Two embodiments are described below as examples, and other embodiments are similar.

[0179] Please continue to refer to Figure 19 , Figure 19 For the time Figure 10 The embodiment shown uses Figure 13 The schematic diagram of the assembly method shown in FIG. 1 is shown in FIG. 2 . In a specific embodiment, as shown in FIG. 2 , Figure 19 As shown, the liquid crystal display screen 11 includes a display panel 111 , a backlight module 112 , a control module 113 , a housing 114 , a support portion 11 a , a sealing member 117 , and a lower frame 114 c . The display panel 111 , the backlight module 112 , and the control module 113 are installed in the housing 114 .

[0180] Specifically, the display panel 111 includes a stacked array substrate 111a, a liquid crystal layer 111b, and a filter layer 111c. The array substrate 111a is disposed on the side of the liquid crystal layer 111b near the backlight module 112, and the filter layer 111c and the array substrate 111a are located on either side of the liquid crystal layer 111b. The control module 113 includes a conversion chip 113a, a flexible circuit board 113b, a driver chip 113c, and a driver circuit board 113d. The support member 11a is connected to the array substrate 111a, and a portion of its structure extends out of the array substrate 111a along the second direction X. The conversion chip 113a can be disposed on the array substrate 111a and electrically connected to the circuitry of the array substrate 111a. The flexible circuit board 113b is bendable, and the driver chip 113c is connected to the driver chip 113c via the flexible circuit board 113b. The driver chip 113c is mounted on the driver circuit board 113d, and the driver circuit board 113d is mounted on the support member 11a. Parts of the driver chip 113c and the driver circuit board 113d extend beyond the array substrate 111a in the second direction X, so that the projection of the display panel 111 in the second direction X does not completely cover the projection of the flexible circuit board 113b, the driver chip 113c, and the driver circuit board 113d in the second direction X.

[0181] Please continue to refer to Figure 19 The lower frame 114c is connected to the side of the shell 114 close to the keyboard along the second direction X. At this time, the projection of the lower frame 114c along the second direction X can cover the projection of the flexible circuit board 113b, the driving circuit board 113d and the driving chip 113c of the control module 113 along the second direction X, so as to shield the flexible circuit board 113b, the driving circuit board 113d, the driving chip 113c, the support member 11a and other structures of the control module 113 to prevent the control module from being exposed.

[0182] Among them, along the second direction X, the side of the seal 117 away from the keyboard cooperates with the shell 114 to seal the gap between the display panel 111 and the shell 114, and the side of the seal 117 close to the keyboard cooperates with the lower frame 114c to seal the gap between the display panel 111 and the lower frame 114c.

[0183] Depend on Figure 19 As can be seen, in this embodiment, the backlight module 112 is connected to the array substrate 111a by a first adhesive 11b and a second adhesive 11c, and is connected to the bottom wall of the housing 114 by a third adhesive 11d.

[0184] It should be noted that Figure 19It can be seen that the driving circuit board 113d and the driving chip 113c of the control module 113 are connected to the side of the array substrate 111a close to the backlight module 112, and the driving circuit board 113d and the driving chip 113c of the control module 113 are distributed along the second direction X with the backlight module 112. The second adhesive is not provided on the side of the array substrate 111a connected to the driving circuit board 113d to reduce the size of the driving circuit board 113d extending from the array substrate 111a along the second direction X, thereby reducing the width of the lower frame 114c.

[0185] Please continue to refer to Figure 20 , Figure 20 For the time Figure 8 The embodiment shown uses Figure 18 The schematic diagram of the assembly method shown in FIG. 1 is shown in FIG. 2 . In a specific embodiment, as shown in FIG. 2 , Figure 20 As shown, the liquid crystal display screen 11 includes a display panel 111 , a backlight module 112 , a control module 113 , a housing 114 , a sealing member 117 and a lower frame 114 c . The display panel 111 , the backlight module 112 and the control module 113 are installed in the housing 114 .

[0186] Specifically, the display panel 111 includes a stacked array substrate 111a, a liquid crystal layer 111b, and a filter layer 111c. The array substrate 111a is disposed on the side of the liquid crystal layer 111b near the backlight module 112, and the filter layer 111c and the array substrate 111a are located on either side of the liquid crystal layer 111b. The control module 113 includes a conversion chip 113a, a flexible circuit board 113b, a driver chip 113c, and a driver circuit board 113d. The conversion chip 113a can be disposed on the array substrate 111a and electrically connected to the circuitry of the array substrate 111a. The flexible circuit board 113b is bendable, and the driver chip 113c is connected to the driver chip 113c via the flexible circuit board 113b. The driver chip 113c is mounted on the driver circuit board 113d, which is mounted on the side of the array substrate 111a away from the liquid crystal layer 111b. The flexible circuit board needs to bypass the side of the array substrate 111a along the second direction X to connect the driving chip 113c and the conversion chip 113a, so that the projection of the display panel 111 along the second direction X cannot completely cover the flexible circuit board 113b.

[0187] Please continue to refer to Figure 20 The lower frame 114c is connected to the side of the shell 114 close to the keyboard along the second direction X. At this time, the projection of the lower frame 114c along the second direction X can cover the projection of the flexible circuit board 113b of the control module 113 along the second direction X, so as to shield the flexible circuit board 113b and other structures of the control module 113 to prevent the control module 113 from being exposed.

[0188] Among them, along the second direction X, the side of the seal 117 away from the keyboard cooperates with the shell 114 to seal the gap between the display panel 111 and the shell 114, and the side of the seal 117 close to the keyboard cooperates with the lower frame 114c to seal the gap between the display panel 111 and the lower frame 114c.

[0189] Depend on Figure 20 As can be seen, in this embodiment, along the first direction Z, the driver circuit board 113d and driver chip 113c are disposed between the backlight module 112 and the array substrate 111a, rendering them inaccessible. To address this, the inner sidewall of the housing 114 is provided with an inwardly protruding support portion 114d. The array substrate 111a is positioned on the support portion 114d and bonded to the support portion 114d via a fourth adhesive 11f. The backlight module 112 is connected to the bottom wall of the housing 114, specifically, by bonding the two via a third adhesive 11d.

[0190] It should be noted that Figure 20 It can be seen that the conversion chip is connected to the side of the array substrate close to the liquid crystal layer 111b, and the driving circuit board 113d and the driving chip 113c of the control module 113 are connected to the side of the array substrate 111a close to the backlight module 112. The flexible circuit board 113b needs to bypass the side end of the array substrate 111a to connect the driving chip 113c and the conversion chip 113a. Therefore, the side wall on the inner side of the shell 114 close to the flexible circuit board 113b is not provided with a support portion 114d to avoid the flexible circuit board 113b, and the support portions 114d on the other three sides are sufficient to support the display panel 111.

[0191] Figure 19 and Figure 20 The above is a possible embodiment when the liquid crystal display screen is installed on the housing. The liquid crystal display screen can also be installed on the housing in other ways, which will not be described in detail in this application.
