What is Graphic Overlay?
Graphic Overlay is A thin polyester or polycarbonate substrate that acts as the top layer of a membrane switch.
Normally,it is silk screen printed or digitally printed onto the second (back) surface,
then adhesive is applied to the back for easy application.
Printing on the second surface allows the substrate to protect the printing from damage.
This process distinguishes an overlay from a label.

In recent years, there has been a growing sentiment that data is the new oil, considered one of the most valuable assets of the 21st century. As big data moves from concept to practical implementation, global development in this field has accelerated significantly due to policy support. Seizing the opportunities brought by the big data era and creating new development prospects have become essential challenges for China.
Big data is no longer just a buzzword—it's now a driving force behind digital transformation. With the integration of information technology into daily life and production, and the rapid spread of the internet, global data volumes are exploding. This has led many to compare data to oil, highlighting its immense value in today’s world.
As a key phase in the evolution of informatization, big data is set to reshape economic growth, social governance, and people’s lives. The saying “whoever controls the data holds the initiative†reflects the strategic importance of this resource. From concept to reality, big data has entered an accelerated development phase, becoming a core driver of innovation and productivity. The management, utilization, and protection of data resources are now central to national competitiveness.
The U.S. was among the first to recognize the strategic importance of big data. In March 2012, it launched a $200 million Big Data Research and Development Plan, aiming to enhance scientific research and national security through better data analysis. Japan followed suit in 2013 with its "Creating the Most Advanced IT Country Declaration," emphasizing the role of big data in improving national competitiveness.
Today, countries around the world are pushing forward with economic digitization as a key driver of innovation. They are making proactive efforts in R&D, data sharing, and security. For China, seizing the opportunity of the big data era and building a new development landscape is not just a challenge—it’s a necessity for progress.
As the Chinese Communist Party’s Political Bureau emphasized during a collective study on December 8, big data is evolving rapidly. It urged careful planning and proactive measures to stay ahead. The goal is to strengthen digital infrastructure, promote data integration and open sharing, ensure data security, and accelerate the construction of Digital China to better serve economic and social development.
To implement the national big data strategy effectively, several areas need attention. First, focus must be placed on breakthroughs in core technologies, with full support from all sectors, including the financial market. Second, a new internet ecosystem should be built, integrating big data across industries and enabling the "Internet +" to take root and deliver real results. Third, data security must be prioritized, with improved regulations and coordinated policies to address potential risks. Finally, the application of big data should be accelerated and made more accessible, such as the recent decision by major telecom operators to eliminate domestic roaming charges ahead of schedule.
Big data is not just a trend—it's the future. And how we harness it will shape the next chapter of global development.
