For people with visual impairments, a refreshable Braille display serves as an important bridge connecting them with the digital world.

As digital information continues to move from paper to electronic devices, traditional Braille display technologies have long faced challenges including high costs, dependence on imported core components, and expensive equipment prices.

These barriers have prevented many visually impaired users from accessing convenient digital reading experiences.

A young engineer is using technological innovation to change this reality.

From Engineering Exploration to Accessibility Innovation

Angelo Li (Li Cheng) has been passionate about engineering and technology since childhood and has always believed that technology should solve real-world problems.

In 2021, while participating in the XbotPark Innovation Camp initiated by Professor Li Zexiang, Angelo Li (Li Cheng) began exploring the information access needs of people with visual impairments.

While most people can easily access digital content through smartphones, tablets, and e-readers, Angelo Li (Li Cheng) started asking:

“How can visually impaired people read and interact with information in the digital world?”

Through user research and technological exploration, he discovered that existing Braille devices still faced challenges such as high costs and limited portability.

This inspired Angelo Li (Li Cheng) and his team to develop a more efficient, reliable, and affordable Braille display solution.

Breaking Technical Barriers and Rethinking Braille Display Technology

Traditional refreshable Braille displays typically rely on piezoelectric ceramic technology, using electronic signals to drive mechanical structures and create Braille dots.

However, because key materials and technologies have long depended on imports, the cost of these devices has remained high.

To address this industry challenge, Angelo Li (Li Cheng) and his team conducted extensive experiments and multiple rounds of technical iteration.

They explored a new electromagnetic-driven approach and independently developed their own Braille display core module.

Through structural innovation and modular design, the team continuously improved:

• Device stability;
  
• Refresh response speed;
  
• Manufacturing efficiency;

while reducing production costs.

Based on this technology pathway, the team developed the early-stage Argus Braille Display prototype, which was later continuously optimized and evolved into the commercial product:

Wiltrue Future 30-Cell Portable Braille Display.

From Technology Prototype to Real User Experience

Throughout the product development process, Wiltrue has always placed user needs at the center.

The team invited visually impaired users to participate in product testing and continuously improved the experience in areas including:

• Braille tactile feedback;
  
• Refresh speed;
  
• Device portability;
  
• Overall usability.

Compared with traditional paper Braille materials, digital Braille devices enable users to access electronic texts more conveniently while expanding possibilities in:

• Reading;
  
• Education;
  
• Professional learning;
  
• Workplace applications.

The Wiltrue Future 30-Cell Portable Braille Display supports Bluetooth connectivity with computers and smartphones and is compatible with mainstream screen readers, enabling visually impaired users to access digital information more independently.

Bringing Advanced Technology to More Users

From laboratory research to commercial products, Wiltrue continues advancing Braille display technology toward solutions that are:

• Smaller;
  
• More portable;
  
• More affordable.

The team is building a broader accessibility ecosystem around:

• Braille display technology;
  
• Smart accessibility terminals;
  
• Digital content solutions.

Through independent research and development, Wiltrue aims to lower the barriers to accessible technology and make digital information more equally available.

During his entrepreneurial journey, Angelo Li (Li Cheng) has applied for:

• 7 invention patents;
  
• 2 utility model patents;
  
• 1 software copyright;

as the first inventor and has received multiple national, provincial, and municipal innovation awards.

Today, Angelo Li (Li Cheng) is the Founder of Wiltrue (Chongqing Infinite Horizons Co., Ltd.).

He continues leading the team in exploring new possibilities at the intersection of artificial intelligence, smart hardware, and information accessibility technology — helping more people access knowledge equally and connect with the digital world.

郦铖：以工程创新，打造更普惠的盲文显示技术

对于视障人士而言，盲文点显器是连接数字世界的重要工具。

随着数字化发展，越来越多的信息从纸张走向电子设备，但传统盲文显示设备长期面临成本高、核心部件依赖进口、产品价格昂贵等问题，让许多视障用户难以享受到便捷的数字阅读体验。

一名年轻工程师，正在尝试通过技术创新改变这一现状。

从工程探索，到无障碍科技创新

从小热爱工程技术的郦铖，一直希望通过技术解决真实问题。

2021年，在参加由李泽湘教授发起的 XbotPark 科创夏令营期间，郦铖开始关注视障群体的信息获取需求。

当普通用户可以通过手机、平板和电子阅读器获取数字内容时，郦铖开始思考：

“视障人士如何阅读数字世界中的信息？”

通过用户调研和技术探索，他发现传统盲文设备仍存在成本高、便携性不足等问题。

于是，郦铖带领团队开始探索更加高效、可靠、普惠的盲文显示技术。

技术突破，重新探索盲文显示方案

传统盲文点显设备通常采用压电陶瓷技术，通过电子信号驱动机械结构产生盲文点位。

然而，由于核心材料和技术长期依赖进口，设备成本一直较高。

针对这一行业难题，郦铖带领团队进行了大量技术实验和方案迭代，探索新的电磁驱动方案，并自主研发盲文显示核心模块。

通过结构创新和模块化设计，团队不断提升设备稳定性、响应速度和生产效率，同时降低制造成本。

基于这一技术路线，团队推出早期产品 Argus盲文点显器，并在持续优化后升级为如今的商业化产品：无界方寸30方盲文点显器

从技术原型，到真实使用体验

产品研发过程中，无界启航始终坚持以用户需求为核心。

团队邀请视障用户参与产品测试，从盲文点触感、刷新速度、设备便携性等多个方面持续优化产品体验。

相比传统纸质盲文资料，数字化盲文设备能够帮助用户更加方便地获取电子文本，并拓展阅读、学习和工作的应用场景。

无界方寸30方盲文点显器支持蓝牙连接电脑和手机，并兼容主流读屏软件，让视障用户能够更加独立地访问数字信息。

让先进技术走向更多用户

从实验室研发，到产品落地，无界启航持续推动盲文显示技术向更小型、更便携、更普惠的方向发展。

目前，团队围绕盲文显示、智能终端和数字内容生态持续布局，希望通过自主研发降低无障碍科技的使用门槛。

创业过程中，郦铖以第一发明人身份申请发明专利7项、实用新型专利2项、软件著作权1项，并获得多项国家级、省市级创新奖励。

如今，郦铖是重庆无界启航创新科技有限公司创始人。

他带领团队持续探索人工智能、智能硬件与信息无障碍技术融合的新方向，让更多人能够平等获取知识，连接数字世界。
