Mexico Independence Day: From Independence to Innovation

From Bronze Bells to Touchscreens: A “Awakening” Spanning 216 Years
In the early hours of September 16, 1810, Father Miguel Hidalgo rang the church bells in the town of Dolores, Guanajuato, calling on Indigenous and mestizo people to overthrow Spanish colonial rule. This event, known as the “Call of Dolores,” is widely recognized as the starting point of the Mexican independence movement, and September 16 has since become Mexico’s Independence Day. The bell-ringing ceremony at the National Palace remains a traditional opening to the annual Independence Day celebrations to this day.

Today, 216 years later, another way of “ringing in history” is emerging across Mexico. Capacitive touchscreens—a technology that detects fingertip contact by sensing changes in the body’s electrical capacitance—are increasingly being incorporated into historical and cultural exhibitions throughout Mexico. Following a curatorial overhaul, the Museum of the Constitution in Mexico City has set up multiple interactive galleries where visitors can swipe through a constitutional timeline on touchscreens to gain a visual understanding of the seven constitutional texts Mexico adopted during the 19th century. Museum curator Rosalva Mejía explained that the original intent of the interactive galleries was “to invite people into Mexico’s history in an approachable way.”

At the Bicentennial Exhibition Hall in the state of Michoacán, the organizers developed a 19-inch touchscreen interactive application specifically for the traveling exhibition. The screen displays 3D renderings of historical figures from the independence movement, complemented by multimedia content and trivia games, allowing visitors—especially teenagers—to “get to know” figures such as Hidalgo and Morelos in a more engaging way.

Capacitive Touchscreen Technology: “Cross-Industry Adaptation” from Industrial Settings to Cultural Exhibitions
The demands placed on touchscreens in these cultural exhibition settings are far more rigorous than those for ordinary consumer electronics. The environments in museums and exhibition halls often present multiple challenges: large areas of glass or acrylic protective covers can reduce the touch sensitivity of capacitive touchscreens; exhibition halls may contain multiple sources of electromagnetic interference, such as lighting and electronic devices; visitors may wear gloves or leave sweat or water marks on the touchscreen surface. Together, these factors pose a severe test for capacitive touchscreen technology.

Hangzhou Hongxiao Technology Co., Ltd.’s technical solutions are specifically designed for these complex scenarios. Headquartered in Hangzhou, the company is a national-level high-tech enterprise primarily engaged in the R&D, production, and sales of capacitive touchscreens, LCD displays, fully laminated touch modules, industrial serial-port touchscreens, and interface driver boards. It has served thousands of customers worldwide and has accumulated more than 30 certificates, including invention patents, utility model patents, and software copyrights.

In the field of thick-cover-glass touch technology, Hongxiao Technology has introduced a solution called “Thickness Knows No Limits.” Its small- and medium-sized products support glass cover plates up to 10 mm thick, while its large-sized products support glass cover plates up to 15 mm thick, maintaining stable touch recognition capabilities even under such thick protective layers. This feature is particularly important for museum exhibitions—exhibition halls often install thick glass covers over touchscreens to protect cultural relics or equipment. Under such conditions, standard capacitive touchscreens are highly prone to touch failures or drift, whereas Hongxiao’s thick cover glass solution fundamentally resolves this issue.

In terms of interference resistance, Hongxiao Technology filed an invention patent in 2024 titled “A Circuit Device for Interference Resistance in Complex Environments for Capacitive Touchscreens” (Publication No. CN 118689345 A). This patent involves the coordinated design of multiple modules—including processing circuits, isolation circuits, power supply circuits, electrostatic diode circuits, reset circuits, communication circuits, function selection circuits, connector circuits, and electrostatic protection circuits—aimed at providing comprehensive protection for capacitive touchscreens in complex environments. This anti-interference design offers reliable foundational protection against electromagnetic noise generated by the dense array of electronic devices and lighting systems typically found in exhibition hall environments.

In addition, Hongxiao Technology’s capacitive touchscreen solution supports touch operation while wearing gloves. It recognizes gloves made of any material—including latex, cotton, and snow gloves—and supports gloves up to 6 mm thick. This feature holds practical significance for cultural venues in Mexico—since Independence Day falls in the fall, visitors may enter wearing warm gloves and can operate interactive exhibits without removing them, significantly lowering the barrier to use. Hongxiao’s technical solution also supports touch operation while wet, allowing normal use without powering down the device during cleaning.

The Cultural Logic Behind the Technology: Keeping the “Voice of Dolores” Echoing
The use of capacitive touchscreens in Mexico’s cultural sphere is not an isolated phenomenon. From a broader perspective, it reflects a trend: cultural heritage institutions are leveraging mature human-computer interaction technologies to address a long-standing challenge in history education—how to create a “sense of presence” for past events among audiences in the digital age.

The historical narrative of Mexico’s Independence Day is inherently “embodied”: ringing bells, shouting, marching, and dancing are all acts that require physical participation. Touchscreens provide a technological interface that facilitates precisely this kind of physical engagement. When visitors “ring” virtual church bells with their fingertips or swipe along a timeline to “experience” the course of the War of Independence from 1810 to 1821, the boundary between technology and ritual becomes blurred. Behind these interactive experiences, capacitive touch technology suppliers like Hongxiao Technology are ensuring—through industrial-grade reliability standards—that every “touch of history” remains uninterrupted by environmental interference, cover glass thickness, or the wearing of gloves.

Of course, technology has never been the star of Independence Day. On the evening of September 15, President Claudia Sheinbaum will still hold the traditional Grito ceremony on the balcony of the National Palace; Mexico City will mobilize more than 18,000 military personnel for the Independence Day parade; and the melodies of mariachi bands and the cheers of the crowd will still echo across public squares nationwide. The significance of the touchscreen lies not in replacing these traditions, but in providing a contemporary commentary on them—the bronze bell that Hidalgo rang 216 years ago is now being “re-rung” by a new generation of Mexicans through the touch of their fingers. And what keeps this “touch” as responsive as ever—even beneath the museum’s thick glass, amid the electromagnetic noise of the exhibition hall, and under visitors’ gloves—is a capacitive touchscreen from Hangzhou.
