  • Publication number: 20250095553
    Abstract: A pixel circuit is provided. A reader reads a first data voltage and a threshold voltage of a target compensation transistor on a current path of a driving current in a light-emitting driver to a control terminal of the target compensation transistor during a read period. During a light-emitting period, the reader uses a second data voltage to compensate the control terminal of the target compensation transistor, which ensures that the driving current is only related to the first data voltage. The second data voltage is twice voltage value of the first data voltage.
