Section 5: Case Study

Industrial HMI Upgrade: From Original LCD to TFT LCD

A European manufacturer of packaging machinery faced challenges with their existing human-machine interface systems. Their legacy equipment utilized Original LCD displays with passive matrix technology, which operators found difficult to read in factory lighting conditions. The 90-degree viewing angle meant that operators had to position themselves directly in front of the display to read critical production parameters, leading to workflow inefficiencies.

The company evaluated the transition from Original LCD to TFT LCD technology and implemented a phased upgrade across their production line. The new 7-inch TFT LCD panels offered 1024x600 resolution with 500 nits brightness and 170-degree viewing angles. The upgrade resulted in a 40% reduction in operator errors related to parameter misreading and a 25% improvement in machine setup times.

Cost analysis showed that while the TFT LCD modules cost approximately $45 each compared to $18 for the Original LCD equivalents, the total cost of ownership over five years was actually 15% lower due to reduced maintenance requirements and improved operational efficiency. The company has now standardized on TFT LCD technology for all new machine designs.
