Abstract: The present application discloses a display-driving method and a display apparatus. The method includes performing an internal compensation to a driving transistor within a display-driving circuit for light-emission in a display-driving time per scan cycle and additionally performing an external compensation via an external-control-sub-circuit in a blanking time between two scan cycles. The method includes using the compensation-control sub-circuit to input a reference voltage to make a driving transistor in conduction state in s start period of the blanking time and increase a voltage level on a sense line associated with the display-driving circuit in an external-compensation period. The method further includes reading the voltage on the sense line at an end of the external-compensation period as a compensation voltage. Furthermore, the method includes using the external-control sub-circuit to correct a data voltage to be supplied to a data line based on the compensation voltage.

Abstract: The present invention provides a wiring structure of high frequency signal wires and a PCB board including the wiring structure of high frequency signal wires. A test part is formed by extending a high frequency signal wire from a connection end connected with a solder pad, and a test window corresponding to a position of the test part is provided on a copper foil which covers the solder pad and the test part, to expose the high frequency signal wire, such that a high frequency signal transmitted via the high frequency signal wire can be directly tested at the test window. Thus, circular test points used in the prior art can be removed, to effectively solve the problem of insufficient space on a PCB; accordingly, lengths of the high frequency signal wires become more precise, so as to ensure a synchronization of transmission of the high frequency signal wires.
