Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display technology, specifically to an in-vehicle liquid crystal display module. Background Technology

[0002] With the rapid development of electronic technology, vehicles now integrate a large number of electronic devices, all displayed on the vehicle's LCD screen. However, vehicles traverse different areas during operation, and the ambient light conditions vary considerably. For example, when entering and exiting tunnels, the light changes rapidly. When entering a tunnel, the onboard LCD screen still emits bright light, which can interfere with the driver's vision. Although some vehicles are equipped with photoresistors to control light changes, the light can still shine directly into the driver's eyes, causing glare and eye fatigue over time, posing a safety hazard. Utility Model Content

[0003] The purpose of this invention is to provide an in-vehicle LCD display module to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a vehicle-mounted LCD display module, including a housing, a positioning component fixedly connected to the upper end of the housing, the positioning component being composed of a positioning horizontal plate and a positioning vertical plate, a back plate being placed at the upper end of the positioning component, and a groove being provided at the upper end of the back plate, in which a reflective sheet for reflecting light is embedded.

[0005] The upper end of the reflector is provided with a first substrate and a second substrate, which form a T-shaped structure. Light sources are provided on both sides of the back plate. The first substrate and the second substrate cooperate with each other to scatter light.

[0006] The upper end of the second substrate is provided with a liquid crystal module, the upper end of the liquid crystal module is provided with a polarizing plate, the upper end of the polarizing plate is provided with a display panel, and photoresistors are provided on both sides of the display panel.

[0007] Preferably, the positioning transverse plate and the positioning longitudinal plate are staggered and form a grid structure, and positioning holes are provided at the staggered positions of the positioning transverse plate and the positioning longitudinal plate.

[0008] Preferably, a positioning post is inserted into the positioning hole, and the positioning post is fixedly connected to the lower end of the back plate.

[0009] Preferably, scattering bumps are embedded on the upper end surface of the first substrate and the lower end surface of the second substrate, and the scattering bumps are evenly distributed on the upper end surface of the first substrate.

[0010] Preferably, one side of the scattering bump is a horizontal surface, and the other side of the scattering bump is an arc-shaped surface, with the two scattering bumps forming a rugby ball structure.

[0011] Preferably, a light-shielding plate is fixedly connected to the upper end of the outer shell, and the cross-section of the light-shielding plate is L-shaped.

[0012] Preferably, the photoresistor is connected to the power supply, and the light source is connected to the liquid crystal module.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: a scattering bump is provided between the first substrate and the second substrate. The scattering bump and the reflector cooperate with each other to refract the light emitted by the light source repeatedly, thereby making the light emitted from the display panel softer, avoiding stimulation of the driver's eyes and reducing driver fatigue; and the scattered light can increase the range of the image projected by the display panel. When the liquid crystal display module is placed in the middle of the vehicle, it can enable the driver to observe more clearly, reduce the driver's head movement range, reduce interference with driving, and increase driving safety.

Obviously, the described embodiments are merely some embodiments of this utility model, not all embodiments, and are not intended to limit the embodiments in any way. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a vehicle-mounted liquid crystal display module, including a housing 1, a positioning member 2 fixedly connected to the upper end of the housing 1, the positioning member 2 being composed of a positioning horizontal plate 21 and a positioning vertical plate 22, a back plate 3 placed on the upper end of the positioning member 2, a groove provided on the upper end of the back plate 3, a reflector 4 for reflecting light embedded in the groove, a first substrate 5 and a second substrate 6 provided on the upper end of the reflector 4, the first substrate 5 and the second substrate 6 forming a T-shaped structure, light sources 8 provided on both sides of the back plate 3, the first substrate 5 and the second substrate 6 cooperating to scatter light, a liquid crystal module 9 provided on the upper end of the second substrate 6, a polarizing plate 10 provided on the upper end of the liquid crystal module 9, a display panel 11 provided on the upper end of the polarizing plate 10, and photoresistors 13 provided on both sides of the display panel 11, the resistance of the photoresistors 13 changing after sensing changes in light.

[0021] The positioning transverse plate 21 and the positioning longitudinal plate 22 are staggered and form a grid structure. Positioning holes 14 are provided at the staggered positions of the positioning transverse plate 21 and the positioning longitudinal plate 22. Positioning pins 15 are inserted into the positioning holes 14. The positioning pins 15 are fixedly connected to the lower end of the back plate 3. After the back plate 3 and the positioning component 2 are installed, the back plate 3 can be limited and fixed.

[0022] Scattering bumps 7 are embedded on the upper end surface of the first substrate 5 and the lower end surface of the second substrate 6. The scattering bumps 7 are evenly distributed on the upper end surface of the first substrate 5. One side of the scattering bump 7 is a horizontal surface and the other side of the scattering bump 7 is an arc-shaped surface. The two scattering bumps 7 form an oval structure. When light reaches the scattering bump 7, part of the light is emitted and part of the light is reflected onto the reflector 4, thereby reducing the glare of the liquid crystal display module when it is working, reducing the driver's eye fatigue, and the scattered light can increase the range of the image projected by the display panel.

[0023] A light-shielding plate 12 is fixedly connected to the upper end of the outer shell 1. The cross-section of the light-shielding plate 12 is L-shaped.

[0024] The photoresistor 13 is connected to the power supply, and the light source 8 is connected to the liquid crystal module 9. When the external light changes, the resistance of the photoresistor 13 changes, thereby controlling the light source to change its brightness and controlling the working brightness of the liquid crystal module 9.
