Description

Technical Field

[0001] This utility model relates to the field of smart education display screen technology, and in particular to a lightweight smart education display screen. Background Technology

[0002] Smart education displays are products specifically designed for educational scenarios, used in classrooms to support teaching and learning activities for teachers and students. They are typically large in size and generally include a backlight module, an LCD panel, and a front frame assembly. The backlight module provides a light source for the LCD panel to display the image. The front frame assembly includes a fixed frame, a glass cover plate mounted on the fixed frame, and an infrared module mounted on the fixed frame. However, due to the large size of the glass cover plate, it is quite heavy and accounts for a significant portion of the overall product weight. This makes the product bulky and inconvenient to manufacture, assemble, and transport. Therefore, it is necessary to propose a new solution to address these issues. Utility Model Content

The fixed frame is connected and fixed to the four sides of the backlight module, and the infrared module is disposed on the fixed frame and corresponds to the four sides of the liquid crystal display panel.

[0006] As a preferred embodiment, the backlight module further includes a cover plate, a reflector, LED chips, a brightness enhancement film, and a light diffuser, wherein the reflector, LED chips, brightness enhancement film, and light diffuser are sequentially arranged on the cover plate.

[0007] As a preferred embodiment, the fixed frame includes four fixed brackets, which are spliced ​​together in a quadrilateral arrangement of two horizontal and two vertical. The infrared module includes a horizontal infrared transmitter, a horizontal infrared receiver, a vertical infrared transmitter, and a vertical infrared receiver. The horizontal infrared transmitter and the horizontal infrared receiver are respectively mounted on the two horizontal fixed brackets, and the vertical infrared transmitter and the vertical infrared receiver are respectively mounted on the two vertical fixed brackets.

[0008] As a preferred embodiment, the ends of two adjacent fixing frames are fixed by L-shaped connectors, and each fixing frame has an insertion interface at its end. The two connecting arms of the L-shaped connector are respectively inserted into the corresponding insertion interfaces and locked with screws.

[0009] As a preferred embodiment, the protective film is an AG film.

[0010] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, its main features are:

[0011] By directly attaching a protective film to the LCD panel and eliminating the glass cover plate in the existing technology, the weight of the product can be greatly reduced by replacing the glass cover plate with a protective film. Based on the structural change, its manufacturing and assembly process is also simplified, reducing manufacturing difficulty and manufacturing cost.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0019] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0020] Please see Figures 1 to 3 This utility model provides a lightweight smart education display screen, including a backlight module 10, a liquid crystal display panel 20, and a front frame assembly 30. The liquid crystal display panel 20 is fixed on the backlight module 10, and a protective film 40 is attached to the liquid crystal display panel 20. The front frame assembly 30 consists of a fixing frame 31 and an infrared module 32. The fixing frame 31 is connected and fixed to the four sides of the backlight module 10, and the infrared module 32 is disposed on the fixing frame 31 and corresponds to the four sides of the liquid crystal display panel 20.

[0021] By directly attaching the protective film 40 to the liquid crystal display panel 20 and eliminating the glass cover plate in the prior art, it is equivalent to replacing the glass cover plate with the protective film 40, which can greatly reduce the weight of the product. Based on the structural change, its manufacturing and assembly process is also simplified, reducing manufacturing difficulty and manufacturing cost.

[0022] Furthermore, the backlight module 10 also includes a cover plate, a reflective sheet, LED beads, a brightness enhancement sheet, and a light diffuser. The reflective sheet, LED beads, brightness enhancement sheet, and light diffuser are sequentially arranged on the cover plate. The backlight module 10 can provide a light source to the liquid crystal display panel 20, thereby realizing the display function. Since the backlight module 10 is prior art and not the focus of this application, it will not be described in detail here, and its specific structure does not need to be shown in the figure. For details, please refer to the prior art.

[0023] Furthermore, the fixed frame 31 includes four fixed brackets 311, which are spliced ​​together in a quadrilateral arrangement of two horizontal and two vertical. The infrared module 32 includes a horizontal infrared transmitter, a horizontal infrared receiver, a vertical infrared transmitter, and a vertical infrared receiver. The horizontal infrared transmitter and the horizontal infrared receiver are respectively mounted on the two horizontal fixed brackets 311, and the vertical infrared transmitter and the vertical infrared receiver are respectively mounted on the two vertical fixed brackets 311. By setting the infrared module 32, the touch sensing function can be realized. The infrared module 32 is existing technology and will not be described in detail here.

[0024] Furthermore, the ends of two adjacent fixing frames 311 are fixed by L-shaped connectors 33. Each fixing frame 311 has an insertion interface 312 at its end. The two connecting arms of the L-shaped connector 33 are respectively inserted into the corresponding insertion interface 312 and locked with screws. The fixing frames 311 are combined by the L-shaped connectors 33, thereby realizing the detachable installation of the fixing frame 31.

[0025] Furthermore, the protective film 40 is an AG film, which is a prior art anti-glare protective film with high light transmittance and anti-fingerprint and anti-oil stains. It is made by spraying a coating on the material surface to scatter light, thereby reducing glare and reflection. It is suitable for various electronic device screens. AG film has high light transmittance and is not easy to leave fingerprints, dust and oil stains, and is easy to clean. In addition, AG film also has high wear resistance and scratch resistance, and has a good operating feel.
