Description

Technical Field

[0001] This utility model relates to the field of touch display technology, and in particular to a touch character display structure. Background Technology

[0002] The touch button display structure refers to an integrated human-computer interaction interface that tightly integrates the touch sensing unit (input function) and the information display unit (output function) in terms of physical space and function.

[0003] Chinese Patent Grant Announcement No.: CN213892181 U, Grant Announcement Date: August 6, 2021. This utility model relates to a novel touch character display structure, including a touch film with an ink layer on which characters are hollowed out; the touch film is attached to a lens. Further, the front of the touch film is attached to the back of the lens, and the back of the lens is mounted on the front of the front frame. Further, a PCBA is mounted on the back of the front frame. Further, an LED light is provided on the PCBA. The shortcomings of this technical solution are: the character display is easily affected by surface reflection, making it inconspicuous and difficult to operate; it is also prone to accidental touches, reducing the user experience of the display structure.

[0004] In summary, the existing display structure has shortcomings such as poor character display quality and difficulty in operation, leading to easy accidental touches. Utility Model Content

[0005] This invention aims to overcome the shortcomings of existing display structures, such as poor character display effects and difficulty in operation leading to accidental touches. It provides a touch character display structure that improves the character display effect, enhances operational convenience, and prevents accidental touches.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A touch character display structure, including The mounting bracket connects the PCB board and the functional diaphragm. The functional diaphragm is electrically connected to the PCB board and has printed characters and patterns. LED light board, the LED light board has several light areas, the light areas are connected to LED beads, the LED beads in the light areas are electrically connected to the PCB board, and the position of the light areas is adapted to the position of the characters and patterns; Diffuser assembly, which is connected to the LED light panel; The display panel is connected to the mounting bracket and is positioned above the diffusion assembly. The functional diaphragm is positioned between the diffusion assembly and the display panel. Cover plate, the display panel is glued to the cover plate; Anti-glare layer, the anti-glare layer is coated on the surface of the cover plate; Anti-reflective layer, which is coated on the surface of the anti-glare layer.

[0007] The PCB board and the functional film with silkscreened characters are connected to the mounting bracket. The functional film is connected to a circuit board and electrically connected to the PCB board, allowing characters to be displayed by applying pressure to the functional film. An LED light board and diffuser assembly illuminate the characters. The LED light board is divided into several light zones corresponding to the positions of the characters. Each light zone is electrically connected to the PCB board via a separate circuit, allowing for zoned lighting control, increasing contrast, and preventing interference between light zones of different characters. The display panel is a bracket for covering the functional film. A cover plate is attached to the display panel and fixed with adhesive to protect the interior of the panel. The cover plate is coated with an anti-glare layer and an anti-reflective layer to reduce reflections and ensure clarity, making the character display clearer while being more comfortable for the eyes and easier to operate. This achieves the effects of improving the display intensity of the characters, ensuring clear display, facilitating operation, and preventing accidental touches.

[0008] Preferably, the diffusion assembly includes a diffusion plate and a insulating film. The diffusion plate is connected to the insulating film, which is connected to the LED light panel. The diffusion plate diffuses the LED light to illuminate the pattern, while the insulating film ensures a certain distance between the LED light panel and the diffusion plate, preventing excessive light mixing. This improves the overall integrity of the diffusion assembly and avoids halos.

[0009] Preferably, a brightness enhancement film is attached to the diffuser plate. This film further focuses the light to illuminate the characters, improving the brightness and uniformity of the front view. This achieves the effect of improving light utilization efficiency and uniformity.

[0010] Preferably, the brightness enhancement film includes a light-controlling film, with one side connected to the brightness enhancement film and the other side connected to the diffuser plate. The light-controlling film is positioned between the brightness enhancement film and the diffuser plate to collect and refract the uniformly scattered light from the diffuser plate into the display area. This achieves the effects of improving display brightness and controlling the light emission angle.

[0011] Preferably, the display panel is connected to a liquid adhesive layer, which connects the display panel to the cover plate. Using the liquid adhesive layer to connect the display panel and the cover plate reduces air gaps between the display panel and the surface glass, increases connection strength, reduces glare caused by air gaps, and improves the silkscreen printing effect of the characters. This achieves the effects of improving structural connection strength, reducing glare, and enhancing the visual experience.

[0012] Preferably, the LED light panel is connected to a light-blocking strip, and the diffuser plate has a positioning groove that matches the light-blocking strip. The light-blocking strip is placed between adjacent light areas. The light-blocking strip divides the LED light group on the LED light panel and fits into the positioning groove of the diffuser plate, making the connection between the diffuser plate and the LED panel tighter. At the same time, it blocks the light from the LEDs in different areas, thereby further improving the prominence of the characters to be operated. This achieves the effects of improving the overall structural assembly, operational accuracy, and preventing accidental touches.

[0013] Preferably, the cover plate is made of glass, and the anti-glare layer is made of hydrogen fluoride. The hydrogen fluoride reacts chemically with the glass to create a micro-uneven structure (AG coating) on ​​the surface of the cover plate, thus reducing specular reflection and glare.

[0014] Preferably, the antireflective layer is made of silicon dioxide, titanium dioxide, and titanium pentoxide. The main optical thin film materials (AR coating) of silicon dioxide (SiO2), titanium dioxide (TiO2), and titanium pentoxide (Ti3O5) are uniformly deposited on the surface of a cover plate with an AG coating to reduce the amount of light directly reflected back to the human eye from the screen surface. This achieves the effect of reducing reflection and improving character display through the combination of AR and AG.

[0015] The beneficial effects of this utility model are: improving the display intensity of characters by the character display structure; providing clear display for easy operation and preventing accidental touches; improving the overall connection of the diffusion component and avoiding halos; increasing display brightness and controlling the light emission angle; and improving the utilization efficiency and uniformity of light.
