Description

Technical Field

[0001] This utility model relates to the field of LCD technology, specifically a novel monochrome liquid crystal display module applied in the field of safe exits. Background Technology

[0002] In various environments such as public buildings and industrial sites, safety exit signage and guidance systems are critical facilities for ensuring the safety of people. Their core function is to provide clear, accurate, and rapid evacuation guidance in emergencies such as fires and earthquakes, ensuring that people can evacuate dangerous areas quickly and orderly.

[0003] Traditional emergency exit display equipment mainly uses fluorescent materials and LED signs. While fluorescent material signs are low-cost, their visibility is significantly reduced in dark environments or complex scenarios such as smoky conditions, making them unsuitable for emergency evacuation. LED signs, with their high brightness and long lifespan, improve visibility to some extent, but their functionality is relatively limited, typically displaying only fixed text or symbol information and unable to dynamically adjust the displayed content according to the actual scene. Therefore, we propose a novel monochrome LCD display module for emergency exit applications to address these issues. Utility Model Content

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.

[0024] Example

[0025] like Figure 1-5 As shown in the figure, a novel monochrome liquid crystal display module for use in the field of safety exits is proposed in one embodiment of the present invention. It includes a module housing 1, an RGB backlight panel 2 inside the module housing 1, a mounting groove 3 on the front side of the RGB backlight panel 2, an LCD cell 4 bonded in the mounting groove 3, an IC chip 5 and a flexible circuit board 6 pressed onto the top of the LCD cell 4, a backlight flexible circuit board 7 soldered onto the flexible circuit board 6, a drive circuit board 8 threadedly connected to the rear side of the RGB backlight panel 2 by multiple bolts 13, an FSLCD connector 9 electrically connected to the rear side of the drive circuit board 8, the FSLCD connector 9 engaging with the flexible circuit board 6, two signal input connectors 10 electrically connected to the rear side of the drive circuit board 8, a salt spray recognition connector 11, a thin code switch 12, and a microcontroller 19 electrically connected to the rear side of the drive circuit board 8.

[0026] In use, the LCD cell 4, as the core component of the display, is pressed together with the IC chip 5 and the flexible circuit board 6 via an ACF film to ensure accurate signal transmission to the LCD cell 4 and realize the display function. The FSLCD connector 9 on the driver circuit board 8 is connected to the flexible circuit board 6, establishing a signal transmission channel between the LCD cell 4 and the driver circuit. The driver circuit provides the required driving signals to the LCD cell 4 through this connection, controlling the alignment of liquid crystal molecules to realize image display. The microcontroller 19, as the core control unit of the entire display module, issues control commands. The driver circuit generates corresponding driving signals according to these commands, precisely controlling the display state of each pixel in the LCD cell 4, and completing the display and content change operations of the LCD cell. The signal input connector 10 is responsible for receiving power and signals from the host computer. These signals contain various information required for the operation of the display module, such as display content commands and brightness adjustment commands. The salt spray recognition connector 11 can monitor the salt spray situation in the environment in real time, thereby enabling the color driving of the monochrome LCD cell 4 through the FS LCD driving mode. With the help of the specific driver circuit board 8, the monochrome LCD can be used in safe touch scenarios.

[0027] In some embodiments, a plurality of double-sided adhesive tapes 14 are adhered to the rear inner wall of the mounting groove 3, and the mounting groove 3 is adhered to the LCD cell 4 by means of the double-sided adhesive tapes 14.

[0028] The double-sided adhesive 14 provides reliable adhesion, firmly fixing the LCD cell 4 in the mounting slot 3, preventing it from loosening, shifting, or even falling off when subjected to vibration, bumps, or external impacts, ensuring the positional stability of the LCD cell 4 during use, and guaranteeing the normal output of the display screen.

[0029] In some embodiments, the LCD cell 4 is provided with an ITO layer 15.

[0030] On the ITO layer 15 inside the liquid crystal cell, the graphic elements are made through etching, exposure, acid washing and other processes. These graphic elements constitute the various basic graphic elements that the display module can display, such as arrows, prohibition signs (red X), etc., providing a basis for displaying different content.

[0031] In some embodiments, a transparent protective shell 16 is movably contacted on the front side of the module housing 1, and two connecting blocks 17 are fixedly connected to both sides of the transparent protective shell 16. The connecting blocks 17 are threadedly connected to the module housing 1 by screws 18.

[0032] The transparent protective shell 16 can effectively protect the LCD cell 4 from scratches and impacts from external objects, while ensuring that the displayed content is clearly visible.

[0033] In some embodiments, the thin code switch 12 has multiple positions, each of which outputs different high and low levels. The microcontroller 19 completes the image change by recognizing the level signal.

[0034] When the user selects different gears by toggling the thin code switch 12, a corresponding level signal is generated. The microcontroller 19 monitors the level signal output by the thin code switch 12 in real time and determines the currently selected gear through the signal recognition function. Based on the different gear information, the microcontroller 19 selects the corresponding image data from the preset image library and displays the image data on the LCD cell 4 through the drive circuit, thereby realizing the image change.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
