Description

Technical Field

[0001] This utility model relates to the field of projector technology, and in particular to an LCD module and a projector. Background Technology

[0002] An LCD projector consists of three basic parts: a light source, an optical system, and an LCD panel module. The strong light emitted by the light source is projected onto the LCD panel through lenses in the optical system. The liquid crystal molecules on the LCD panel change under the influence of an electric field, and through the modulation of the RGB primary colors, an image is ultimately formed. The LCD panel is the main component forming the image, and its aperture ratio and temperature resistance directly affect the brightness of the projection; simultaneously, the resolution of the LCD panel directly affects the detail and clarity of the projected image.

[0003] Currently, LCD screens are typically fixed inside projectors using either plastic brackets or adhesive bonding. Using plastic brackets requires completely surrounding the LCD screen before securing it to the projector. This method is not only complex but also prone to damaging the screen during assembly, as it can contaminate the screen surface and affect projection quality. Adhesive bonding, on the other hand, involves gluing the LCD screen to the projector's internal mounting bracket. During prolonged projector operation, the high temperatures can cause the adhesive to degrade, leading to screen detachment. This method lacks stability and practicality.

[0004] Therefore, there is an urgent need to provide a new type of LCD module and projector to solve the above-mentioned technical problems in the existing technology. Utility Model Content

[0032] Please refer to Figure 1 and Figure 2 The LCD module includes a mounting frame 100, a liquid crystal panel 200, and a fixing clip 300. The mounting frame 100 includes a fixed frame 110, a horizontal frame 120, and two side frames 130. The fixed frame 110 and the horizontal frame 120 extend along a first direction, and the side frames 130 extend along a second direction. The fixed frame 110 and the horizontal frame 120 are arranged opposite to each other, and the two side frames 130 are arranged opposite to each other. The horizontal frame 120 has a first groove 121, and the side frames 130 have a second groove 121. 31. The two ends of the first groove 121 along the first direction are connected to the two second grooves 131 respectively; the first groove 121 and the two second grooves 131 are arranged to form a fixing groove, the liquid crystal panel 200 is snapped into the fixing groove, the outer wall of the first end of the fixing frame 110 along the third direction is flush with the inner side wall of the second end of the fixing groove along the third direction; the fixing buckle 300 is disposed on the fixing frame 110, and at least a portion of the liquid crystal panel 200 is sandwiched between the fixing buckle 300 and the fixing frame 110.

[0033] In this embodiment, the LCD module uses a mounting frame 100 and a fixing buckle 300 to fix the LCD panel 200. Specifically, during installation, the mounting frame 100 is composed of a fixed frame 110, a horizontal frame 120, and two side frames 130. The horizontal frame 120 has a first groove 121, and the two side frames 130 each have a second groove 131. The first groove 121 and the second groove 131 form a fixing groove to accommodate the LCD panel 200. The outer wall of the fixed frame 110 at the first end is flush with the outer wall of the fixing groove at the second end. During installation, the LCD panel 200 can be slid into the fixing groove from one end of the fixed frame along the second direction to fix the LCD panel 200 in the third direction and the first direction. Then, the fixing buckle 300 is installed to fix the LCD panel 200 in the second direction, thereby fixing the LCD panel 200 on the mounting frame 100. This LCD module can improve the fixing effect of the LCD panel 200 and make the installation of the LCD panel 200 more convenient. The LCD panel 200 can be easily slid into the fixing groove and then fixed for a second time using the fixing buckle 300. Not only is the fixing effect better, but it can also prevent contamination and damage to the LCD panel 200 during the installation process, thereby improving the production quality and yield of the final LCD module.

[0034] like Figure 2 As shown, the aforementioned fixing buckle 300 includes a connecting portion 310 and latching portions 320 connected to both ends of the connecting portion 310 along the third direction. One of the two latching portions 320 latches onto the fixing frame 110, and the liquid crystal panel 200 is sandwiched between the other latching portion 320 and the fixing frame 110. This fixing buckle 300, by latching onto the fixing frame 110 with the latching portion 320, reliably fixes the fixing buckle 300 to the fixing frame 110, while simultaneously using the other latching portion 320 to firmly press the liquid crystal panel 200 onto the fixing frame 110, thus achieving reliable fixation of the liquid crystal panel 200 in both the third and second directions.

[0035] Furthermore, two fixing clips 300 are provided, and the two fixing clips 300 are respectively located at both ends of the fixing frame 110 along the first direction. The arrangement of two fixing clips 300 can limit and fix the liquid crystal panel 200 at both ends along the first direction, and the fixing effect is better.

[0036] like Figures 2 to 4As shown, both of the aforementioned snap-fit ​​portions 320 are provided with snap-fit ​​grooves 321. The outer wall of the second end of the fixed frame 110 along the third direction is provided with a first snap-fit ​​protrusion 111, and the outer wall of the side frame 130 along the first end along the third direction is provided with a second snap-fit ​​protrusion 132. One of the two snap-fit ​​grooves 321 engages with the first snap-fit ​​protrusion 111, and the other engages with the second snap-fit ​​protrusion 132. Thus, the two snap-fit ​​portions 320 can be fixed to the second end of the fixed frame 110 and the first end of the side frame 130, thereby fixing both ends of the fixing buckle 300 along the third direction to the mounting frame 100, achieving a stable fixation of the fixing buckle 300, and providing a better fixation effect for the LCD panel 200.

[0037] In this embodiment, the fixed frame 110 has a fixing groove 112 recessed at both ends along the first direction and at the end away from the horizontal frame 120 along the second direction. The inner sidewall of the fixing groove 112 is provided with the first snap-fit ​​protrusion 111, and the fixing buckle 300 is fitted and accommodated in the fixing groove 112. The fixing groove 112 not only improves the fixing effect of the fixing buckle 300 on the fixed frame 110, but also reduces the installation space of the fixing buckle 300 on the mounting frame 100, reduces the volume of the LCD module, and facilitates the installation of the LCD module in the projector.

[0038] like Figure 3 and Figure 4 As shown, both the fixed frame 110 and the horizontal frame 120 are connected to the outer wall of the second end of the side frame 130 along the third direction. This arrangement reduces the space occupied by the fixed frame 110 and the horizontal frame 120 in the third direction, reduces the material used in the mounting frame 100, thereby reducing production costs and the weight of the mounting frame 100.

[0039] In this embodiment, the first groove 121 is formed by the horizontal frame 120 recessing downwards from the outer wall of the first end in the third direction toward the second end. The liquid crystal panel 200 abuts against the inner sidewall of the second end of the first groove 121 in the third direction. That is, the first groove 121 only abuts and fixes the second end of the liquid crystal panel 200 in the third direction, making it easier for the liquid crystal panel 200 to be placed into the first groove 121. This not only improves installation efficiency but also enhances installation convenience and avoids damage to the liquid crystal panel 200 during installation.

[0040] Furthermore, the outer wall of the first end of the fixed frame 110 along the third direction is flush with the inner sidewall of the second end of the first groove 121 along the third direction. Thus, the first groove 121 and the fixed frame 110 can effectively fix and support the second end of the LCD panel 200 along the third direction, resulting in better fixing effect and greater stability of the LCD panel 200 after installation.

[0041] Optionally, the second groove 131 is formed by recessing the outer wall of the second end of the side frame 130 along the third direction toward the first end, and the liquid crystal panel 200 abuts against the inner side wall of the second groove 131 along the third direction at the first end. That is, the second groove 131 only abuts and fixes the first end of the liquid crystal panel 200 along the third direction, making it easier for the liquid crystal panel 200 to be placed into the second groove 131. By using the first groove 121 and the second groove 131 to fix the two ends of the liquid crystal panel 200 along the third direction, not only is the installation efficiency improved, but the ease of installation is also improved, and damage to the liquid crystal panel 200 is avoided during installation.

[0042] This embodiment also provides a projector that includes an LCD module as described in any of the above embodiments. The LCD module used in this projector improves the fixation effect of the liquid crystal panel 200, and makes the installation of the liquid crystal panel 200 more convenient. The liquid crystal panel 200 can be easily slidably placed into the fixing slot, and then secondary fixation is performed using the fixing clips 300. This not only provides a better fixation effect but also prevents contamination and damage to the liquid crystal panel 200 during installation, improving the final production quality and yield of the LCD module, and thus improving the production quality of the projector.

[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
