[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The purpose of this invention is to provide a ruggedized liquid crystal display module to solve the problems existing in the prior art.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] The ruggedized liquid crystal display module in this embodiment, such as Figure 1-5 As shown, the system includes a metal frame 1, an LCD screen 2, a backlight 3, a driver circuit board 4, buffer pads 5, and a heat sink 6. The LCD screen 2, backlight 3, and driver circuit board 4 are arranged sequentially from the outside to the inside within the metal frame 1. The backlight 3 is positioned close to the LCD screen 2. Buffer pads 5 are respectively positioned between the backlight 3 and the driver circuit board 4, and between the driver circuit board 4 and the inner bottom surface of the metal frame 1. The heat sink 6 is positioned between the backlight 3 and the metal frame 1. The metal frame 1 provides fixation and drop protection for each module unit; the LCD screen 2 is the display component; the backlight 3 is the lighting device; the buffer pads 5 are used to achieve shock absorption and cushioning between the display screen, driver circuit board 4, and metal frame 1, avoiding hard contact between the LCD screen 2 and the metal frame 1. In harsh vibration and impact environments, they provide excellent vibration isolation and cushioning, protecting the LCD screen 2; the heat sink 6 conducts the heat generated by the backlight 3 to the metal frame 1, serving an internal heat dissipation function.

[0026] like Figure 5 As shown, the metal frame 1 is a rectangular frame made of aluminum alloy. Inside the metal frame 1, a first shoulder 7, a second shoulder 8, and a bottom groove 9 are arranged sequentially inward. The purpose of the first shoulder 7 is to cooperate with the buckle 10 to attach the LCD screen 2, and the second shoulder 8 protrudes from the bottom groove 9.

[0027] like Figures 3-4As shown, the LCD screen 2 is fastened to the first shoulder 7 by clips 10, which are fixed to the inner edges of the two short sides of the metal frame 1. Clips 10 are right-angled triangular strips with a short right-angle side length of 0.2cm and a long right-angle side length of 0.25cm, for a total length of 4cm. The short right-angle side of the clip 10 is welded to the metal frame 1, while the long right-angle side is parallel to the LCD screen 2 and protrudes from the inner edge of the metal frame 1. Five clips 10 are located on the inner edge of each short side of the metal frame 1, evenly distributed along the inner edge of the short side. The inner periphery of the LCD screen 2 is supported by the first shoulder 7, while the two short sides of the LCD screen 2 are secured to the metal frame 1 by the clips 10.

[0028] In this specific embodiment, the backlight 3 is disposed between the LCD screen 2 and the second shoulder 8. The buffer pad 5 is used to realize the shock absorption and buffering effect between the display screen, the driving circuit board 4 and the metal frame 1, avoiding hard contact between the LCD screen 2 and the metal frame 1. Under severe vibration and impact environment, it plays a good vibration isolation and buffering effect, protecting the LCD screen 2. Specifically, the buffer pad 5 includes buffer pad 5-1 and buffer pad 5-2. Buffer pad 5-1 is L-shaped. The horizontal part of buffer pad 5-1 is located between the top surface of the backlight 3 and the metal frame 1. The vertical part of buffer pad 5-1 extends vertically and is located between the second shoulder 8 above the bottom groove 9 and the driving circuit board 4 and the backlight 3. That is, the inner side of the vertical part of buffer pad 5-1 contacts the upper second shoulder 8 and the driving circuit board 4 respectively. Buffer pad 5-1 fixes the driving circuit board 4 with adhesive. Buffer pad 5-2 is located between the driving circuit board 4 and the bottom groove 9.

[0029] In this specific embodiment, a heat sink 6 is provided between the second shoulder 8 below the bottom groove 9 and the backlight 3. The heat sink 6 conducts the heat generated by the backlight 3 to the metal frame 1, thereby playing the role of internal heat dissipation.
