  • Passive matrix organic light emitting display panels having touch sensors using anode and cathode electrodes
    Patent number: 10318085
    Abstract: A PMOLED touch-sensing display panel using anodes as in-cell touch sensors is provided. The anodes and the cathodes are respectively and correspondingly configured into two or more electrically isolated areas of cathodes and anodes such that the heavy parasitic capacitance due to close proximity of the anode layer and the cathode layer is eliminated, hence providing a full dynamic range in sensing the changes in capacitance due to finger touches.
    Type: Grant
    Filed: October 26, 2017
    Date of Patent: June 11, 2019
    Assignee: SOLOMON SYSTECH (SHENZHEN) LIMITED
    Inventors: Wing Chi Stephen Chan, Wai Hon Ng, Sing Ng, Hon Sheung Liu, Yip Fai Li, Wai Lan Ng, Johnkid Lo
