Solomon Systech Launches Innovative Integrated Chip Technology Set to Transform PMOLED Display Technology

Hong Kong Science and Technology Parks Corporation (HKSTP) is proud to witness another world’s first invention emerging from Hong Kong Science Park.

Long-standing partner company Solomon Systech Limited has launched a Touch and Display Driver Integration (TDDI) IC that is set to transform the touch and display technology for Passive Matrix OLED (PMOLED) panels.

Solomon Systech’s patent-filed SSD7317 PMOLED TDDI IC integrates touch and display micro-electronics into a single chip, the first time this is achieved for use on PMOLED display panels. It delivers high-quality display and touch performance, and enables a thinner and lighter PMOLED touch and display module form factor, in addition to lowering costs and reducing manufacturing time and processes.

Peter Yeung, Head of Electronics & ICT Clusters, Smart City Platform, HKSTP, applauded the latest achievement of the listed Park company. “Solomon Systech’s success in developing a revolutionary IC is yet another example that Hong Kong’s innovation and technology ecosystem has the talent and knowhow to develop world-leading innovations. Solomon Systech has been based at Science Park since 2003, and is amongst the first batch of companies to move into Science Park. Its success reflects HKSTP’s commitment to providing the right support for Park companies at different stages of their development, and creating the ideal environment for Park companies to translate R&D results into real-life applications.”

Extensive Applications For Innovative Devices In The IoT Era

Solomon Systech’s new integrated IC enables in-cell touch detection on traditional PMOLED display modules with no modification required. It also supports four-zone touch detection, gesture identification and operation with gloves or wet fingers. It is anticipated to have wide applications for wearables, smart home appliances and healthcare devices, extending the applications of PMOLED technology to power the Internet of Things (IoT) devices.

“This ground-breaking innovation has set an important milestone in the PMOLED industry worldwide,” said Raymond Wang, Solomon Systech Limited’s Corporate Vice President and Head of Advanced Display Business Unit. “As a pioneer and a market leader of PMOLED display driver ICs, we are ready to leverage this world’s first PMOLED TDDI IC to cater to surging market needs and push for further growth.”

Key Competitive Advantages of PMOLED TDDI IC SSD7317’s In-cell Touch Technology:

  • Enables better display quality given higher light transmittance
  • Enhances touch performance with the proprietary time multiplexing approach reducing display and touch crosstalk
  • Decreases total module costs by reducing the total number of components
  • Improves yield rate of final product assembly
  • Shortens development cycle
  • Enables ultra-slim form factor
  • With 7 patents filed globally
