Abstract
A pixel circuit, which may include a first pixel unit having a first display driving circuit (12), a first pixel electrode (P1), and a first control circuit (11), and a second pixel unit having a second display driving circuit (22), a second pixel electrode (P2), and a second control circuit (21). The first control circuit (11) may be configured to adjust and latch a voltage of a first positive phase node (Q1) and the first display driving circuit (12). The first display driving circuit (12) may be configured to provide a first display driving voltage to the first pixel electrode (P1). The second control circuit (21) may be configured to adjust and latch a voltage of a second positive phase node (Q2) and the second display driving circuit (22). The second display driving circuit (22) may be configured to provide a second display driving voltage to the second pixel electrode (P2).
