  • Publication number: 20230395021
    Abstract: The present specification discloses a pixel driving circuit having a reduced number of external contacts. A conventional digital driving pixel requires two contacts (Vcc, GND) related to power, a contact (row signal, column signal) for inputting two signals for digital driving, a contact (mode selection) for inputting a set value required for driving the pixel, and a contact (reset) for maintaining video data for one frame to implement a cycle function during PWM driving and for inputting a reset signal to clear previous video data before inputting new video data. However, the higher the number of contacts, the lower the efficiency of pick & place in the manufacturing process. Thus, in the present specification, a pixel driving circuit is proposed, which can be digitally driven even when the number of contacts is reduced through combination of a row signal and a column signal.
