DETAILED DESCRIPTION

[0023] This specific embodiment is a liquid crystal screen for displaying vehicle integrated safety functions, and its structural diagram is as follows Figures 1-4 As shown, the LCD screen includes a display screen 1, a mounting shell 2 and a power supply 3. A conventional circuit board, a control IC chip, a radio frequency chip, a power interface, etc. are installed inside the mounting shell 2, so that the display screen 1 is used to display the safety operation data of various parts of the vehicle. The display screen 1 is installed inside the mounting shell 2. The display screen 1 adopts a monochrome, positive display, and full-viewing angle display screen. The display screen 1 includes a dot matrix LCD module group 4 and a character liquid crystal module group 5. The power supply 3 includes a solar panel 6, a battery 7 and a controller 8. The solar panel 6 and the battery 7 are both electrically connected to the controller 8, and the controller 8 is electrically connected to the display screen 1. Since the monochrome, positive display, and full-viewing angle display screen uses solar energy as a power source, it reduces dependence on traditional power sources and energy-saving and environmental protection issues, improves energy utilization efficiency, and does not need to use a vehicle battery to power the display screen 1, avoiding the problem of easily exhausting the power in the vehicle battery due to long-term use. In addition, the vehicle does not need to be in the starting state, does not consume oil, and does not pollute the atmosphere. At the same time, solar energy is a renewable energy source with a wide range of uses, which is in line with the country's industrial direction.

[0024] like Figure 1 and Figure 4 As shown: In this embodiment, the left and right sides of the display screen 1 are fixedly connected with a flexible cable 9, and the flexible cable 9 is installed with a connecting plug 10 and a power supply port 11. This arrangement facilitates installation and disassembly, making the connection of the display screen 1 more convenient.

[0025] In this embodiment, the display screen 1 is a liquid crystal screen with black characters on a yellow background or a liquid crystal screen with black characters on a gray background.

[0026] This setting gives the monochrome, positive display, full-viewing angle display its unique advantages. It can clearly display Chinese characters, graphics, characters, etc. within the visual angle. The display effect of the yellow background black text LCD screen or the gray background black text LCD screen under sunlight is more prominent than that of the general color screen.

[0027] like Figure 1 and Figure 4 As shown: In this embodiment, the dot matrix LCD module group 4 is composed of multiple 2864 liquid crystal modules.

[0028] The LCD screen is designed with low power consumption, which can effectively reduce energy consumption. It also has the advantages of clear digital display interface and wide viewing angle. It can not only improve energy utilization efficiency, but also improve driving safety and convenience. It is a very practical vehicle-mounted equipment display device.

[0029] like Figure 1 and Figure 4 As shown: In this embodiment, the character liquid crystal module group 5 is composed of multiple 0802 liquid crystal modules or 1602 liquid crystal modules.

[0030] This setting adopts a low-power design for the LCD screen, which can effectively reduce energy consumption, and has the advantages of clear text and symbols on the display interface and a wide viewing angle.

[0031] like Figure 1 and Figure 2 As shown: In this embodiment, a buckle 12 is provided inside the mounting shell 2, and the display screen 1 is detachably connected to the mounting shell 2 through the buckle 12. This makes it more convenient to disassemble the display screen 1 and the mounting shell 2, which is convenient for later maintenance.

[0032] like Figure 2 and Figure 3 As shown: In this embodiment, the solar panel 6 is mounted on the top of the vehicle by screws, and the display screen 1 is mounted inside the vehicle;

[0033] This arrangement allows the solar panel 6 to better receive sunlight and provide stable power for the display screen 1. The solar panel 6 can also be installed on the top of the vehicle through an adjustable bracket. By adjusting the position of the bracket, the solar panel 6 can always face the sunlight.

[0034] In this embodiment, the battery 7 is fixedly connected to the inside of the mounting shell 2. The battery 7 uses lithium iron phosphate cells and applies a high-specification BMS battery management system. It is plug-and-play and has a stable power supply voltage.

[0035] Working principle: The design takes into account the country's industrial direction and low-carbon environmental protection, and adopts solar energy as the best choice of equipment energy. By setting solar panels 6, batteries 7 and controller 8, the solar panels 6 and batteries 7 are electrically connected to the controller 8, and the controller 8 is electrically connected to the display screen 1. The required material and energy absorption of the solar panels 6 and the storage capacity of the battery 7 are designed according to the total power consumption and usage time of the equipment. The use of monochrome, positive display, and full-viewing angle display further reduces the power consumption. When the solar panel 6 has no power, the battery 7 can be used to power the display screen 1 through the controller 8. When the solar panel 6 has power, it directly powers the display screen 1. In this way, while ensuring the use of the equipment, the energy structure is optimized, which not only extends the use time of the equipment, responds to the country's requirements for energy conservation and emission reduction, but also meets the power supply needs of the equipment.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
