Description

Technical Field

[0001] This utility model relates to the field of LCD screen technology, and in particular to an LCD screen that is easy to install. Background Technology

[0002] Mobile phone touchscreens, also known as touch panels, are a type of flat panel display. They have many advantages, such as low power consumption and small size, and are widely used in various electronic devices. The various parts of an LCD screen are relatively thin, making it prone to damage. Therefore, related technologies often assemble the outer and inner screens of the LCD screen sequentially onto a back panel, and then frame this overall structure with a bracket. However, the bracket itself is quite fragile and easily damaged during installation.

[0003] In related technologies, in order to avoid damage to the bracket itself, the bracket no longer adopts a separate frame structure, but adopts an integrated bracket structure that wraps around the periphery of the LCD screen structure and the backlight panel. The periphery of the bracket structure is tightly connected to the outer periphery of the LCD screen, but the various parts of the LCD screen need to be glued together with optical adhesive. When installing it into the bracket structure, the whole process is more difficult, and the bracket structure may damage the LCD screen structure. Utility Model Content

[0004] The main purpose of this utility model is to provide an easy-to-install LCD screen, which is designed to make the LCD screen easy to install and has a strong structure.

[0005] To achieve the above objectives, this utility model proposes an easy-to-install LCD screen, comprising a screen structure and a support structure;

[0006] The screen structure includes an outer screen, an inner screen, and a backlight panel stacked sequentially. The outer peripheral edges of the outer screen, the inner screen, and the backlight panel are aligned with each other on a projection perpendicular to the stacking direction.

[0007] The bracket structure has a base plate opposite the backlight panel, and a protective structure protrudes from the outer periphery of the base plate. The protective structure and the side of the base plate facing the backlight panel form a mounting cavity.

[0008] The screen structure is housed within the mounting cavity, and the height of the protective structure is greater than or equal to the sum of the thickness of the backlight panel and the thickness of the inner screen.

[0009] A connecting structure for guiding the installation of the backlight panel is provided between the base plate and the backlight panel.

[0010] In one embodiment of this application, the connecting structure is a connecting rod, the base plate is provided with a relief groove relative to the connecting rod, one end of the connecting rod is rotatably connected to one end of the relief groove, the backlight panel is provided with a connecting block at the other end facing the connecting rod, and the connecting rod is rotatably connected to the connecting block; when the backlight panel is housed in the mounting cavity, the connecting block and the connecting rod are housed in the relief groove.

[0011] In one embodiment of this application, at least two connection structures are provided, and the two connection structures are symmetrically arranged on the base plate.

[0012] In one embodiment of this application, one end of the inner screen is connected to a circuit board, the protective structure has a through slot relative to the circuit board, and the circuit board passes through the through slot.

[0013] In one embodiment of this application, a light-shielding sheet is provided at one end of the outer screen facing the circuit board, and the end of the light-shielding sheet away from the outer screen is connected to the backlight panel and covers the inner screen;

[0014] At least two light-shielding sheets are provided on both sides of the circuit board, with one side of each light-shielding sheet connected to the circuit board and the other side connected to the through slot.

[0015] In one embodiment of this application, the outer screen faces the inner screen, and a mounting groove is provided at one end near the circuit board, and one end of the light-shielding sheet is connected to the mounting groove.

[0016] By adopting the above technical solution, this utility model has the following advantages:

[0017] The LCD screen of this application includes a screen structure consisting of an outer screen, an inner screen, and a backlight panel, and also includes a bracket structure for mounting and protecting the screen structure. The outer peripheries of the outer screen, inner screen, and backlight panel are aligned with each other and bonded together with optical adhesive to form a whole. This structure enables the various parts of the screen structure to support each other, effectively improving the overall structural strength and preventing damage.

[0018] The support structure includes a base plate and a protective structure. The protective structure surrounds the outer perimeter of the base plate and protrudes towards the screen structure. The mounting cavity formed by the protective structure and the base plate can be used to install the protective screen structure. The core part of the screen structure is the inner screen. The height of the protective structure is at least enough to ensure that the inner screen is completely within the mounting cavity for protection, making it easy to install the entire LCD screen after assembly.

[0019] A connecting structure is provided between the bottom and the backlight panel. In one feasible embodiment, the connecting structure can be a connecting pivot between the bottom and the backlight panel, allowing one end of the backlight panel to rotate on the bottom plate.

[0028] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0030] The following is in conjunction with the appendix Figures 1 to 5 The present invention will be further described below.

[0031] To achieve the above objectives, this utility model proposes an easy-to-install LCD screen, comprising a screen structure 1 and a support structure 5.

[0032] The screen structure 1 includes an outer screen 2, an inner screen 3, and a backlight panel 4 stacked sequentially. The outer edges of the outer screen 2, the inner screen 3, and the backlight panel 4 are aligned with each other on a projection perpendicular to the stacking direction.

[0033] The bracket structure 5 is provided with a base plate 51 relative to the backlight plate 4. A protective structure 53 protrudes from the outer periphery of the base plate 51. An installation cavity 6 is formed on the side of the protective structure 53 and the base plate 51 facing the backlight plate 4.

[0034] The screen structure 1 is housed in the mounting cavity 6, and the height of the protective structure 53 is greater than or equal to the sum of the thickness of the backlight panel 4 and the thickness of the inner screen 3.

[0035] A connecting structure 7 for guiding the installation of the backlight panel 4 is provided between the base plate 51 and the backlight panel 4.

[0036] The LCD screen of this application includes a screen structure 1 consisting of an outer screen 2, an inner screen 3, and a backlight panel 4, and also includes a bracket structure 5 for mounting and protecting the screen structure 1. The outer peripheries of the outer screen 2, the inner screen 3, and the backlight panel 4 are aligned with each other and bonded together with optical adhesive to form a whole. This structure enables the various parts of the screen structure 1 to support each other, effectively improving the overall structural strength and preventing damage.

[0037] The support structure includes a base plate 51 and a protective structure 53. The protective structure 53 surrounds the outer periphery of the base plate 51 and protrudes towards the screen structure 1. The mounting cavity 6 formed by the protective structure 53 and the base plate 51 can be used to install the protective screen structure 1. The core part of the screen structure 1 is the inner screen 3. The height of the protective structure 53 is at least enough to ensure that the inner screen 3 is completely within the mounting cavity 6 for protection, which makes it easy to further install the entire LCD screen after assembly.

[0038] A connecting structure 7 is provided between the bottom and the backlight panel 4. In one feasible embodiment, the connecting structure 7 can be a connecting shaft between the bottom and the backlight panel 4, allowing one end of the backlight panel 4 to rotate on the base plate 51. This connecting structure 7 has a safety limiting function. When the backlight panel 4 is removed from the mounting cavity 6 or accidentally loosens, the backlight panel 4 can be restrained by the connecting shaft and the rotating connecting structure 7, preventing it from completely detaching from the bracket. This avoids the screen structure 1 from falling, bumping, and the hard pulling of the connecting cables, improving the safety and convenience of the maintenance process. At the same time, the connecting structure 7 also has installation guiding performance. After the other parts of the screen structure 1 are installed on the backlight panel 4, the connecting shaft can guide the screen structure 1 through its own rotation, allowing the entire screen structure 1 to rotate naturally and accurately and be positioned in the predetermined position of the mounting cavity 6. This simplifies the installation operation and improves the assembly efficiency and accuracy.

[0039] In one embodiment of this application, the connecting structure 7 is a connecting rod, the base plate 51 is provided with a relief groove 52 relative to the connecting rod, one end of the connecting rod is rotatably connected to one end of the relief groove 52, the backlight plate 4 is provided with a connecting block 41 facing the other end of the connecting rod, and the connecting rod is rotatably connected to the connecting block 41; when the backlight plate 4 is housed in the mounting cavity 6, the connecting block 41 and the connecting rod are housed in the relief groove 52.

[0040] The connecting rod also serves as a safety limit and installation guide, and its effect is better than that of the connecting shaft. The connecting rod can restrain the screen structure 1 and can completely separate the screen structure 1 from the mounting cavity 6, which makes it easy for the backlight panel 4 to install other parts of the screen structure 1 outside the mounting cavity 6, ensuring the convenience of installation. In addition, the connecting rods fixed at both ends act as a traction, which enables the screen structure 1 to be quickly installed in the bracket structure 5.

[0041] The clearance groove 52 can completely accommodate the connecting rod, avoiding gaps between the bottom of the screen structure 1 and the mounting groove 21 caused by the connecting rod, which could lead to unstable installation. The end of the connecting rod away from the bracket structure 5 is provided with a storage groove, and the connecting block 41 is located in the storage groove. The combined thickness of the storage groove and the connecting block 41 is the same as the thickness of the connecting rod, so that the entire connecting rod and the connecting block 41 can be completely accommodated in the clearance groove 52. This ensures that the screen structure 1 can be installed quickly while improving the stability of the installed structure.

[0042] In one embodiment of this application, at least two connecting structures 7 are provided, and the two connecting structures 7 are symmetrically arranged on the base plate 51.

[0043] At least two connecting structures 7 can ensure the installation stability and structural strength of the screen structure 1, prevent structural damage, and make the traction guiding force of the connecting structure 7 more accurate and stable.

[0044] In one embodiment of this application, one end of the inner screen 3 is connected to a circuit board 31, and the protective structure 53 is provided with a through groove 54 relative to the circuit board 31, through which the circuit board 31 passes.

[0045] The protective structure 53 can shield the inner screen 3, thus preventing light leakage from the inner screen 3. Since the inner screen 3 needs to be connected to the circuit, the circuit board 31 can be passed through the through slot 54 of the protective structure 53, which makes the entire LCD screen easier to install.

[0046] In one embodiment of this application, a light-shielding sheet 22 is provided at one end of the outer screen 2 facing the circuit board 31, and the end of the light-shielding sheet 22 away from the outer screen 2 is connected to the backlight plate 4 and covers the inner screen 3.

[0047] At least two light-shielding sheets 22 are provided on both sides of the circuit board 31, with one side of each light-shielding sheet 22 connected to the circuit board 31 and the other side connected to the through groove 54.

[0048] Because the specifications of the circuit boards 31 on the inner screen 3 are different, the protective structure 53 needs to open the through slot 54 and cannot maintain a good light leakage prevention effect. Therefore, a light-shielding sheet 22 is provided on the outer screen 2. The width of the light-shielding sheet 22 is the width of the through slot 54. When corresponding to different specifications of circuit boards 31, after the inner screen 3 and the outer screen 2 are installed, the light-shielding sheet 22 on both sides can be retained by cutting. This allows the light-shielding sheet 22 on both sides to be connected to the through slot 54 on one side and the circuit board 31 on the other side, so that the whole structure has good light-shielding performance and is easy to connect.

[0049] In one embodiment of this application, the outer screen 2 faces the inner screen 3, and a mounting groove 21 is provided at one end near the circuit board 31, and one end of the light shield 22 is connected to the mounting groove 21.

[0050] The mounting slot 21 facilitates the installation of the light shield 22 itself and prevents gaps between the outer screen 2 and the inner screen 3 caused by the light shield 22.

[0051] To prevent the light-shielding sheet 22 from coming off, in one feasible embodiment, a mounting post can be protruded into the mounting groove 21, so that the mounting post passes through the light-shielding sheet 22, which can make the light-shielding sheet 22 more securely installed in the mounting groove 21 and enhance the overall structural strength.
