Abstract: The present disclosure provides a circuit board, an electrical component and a display apparatus. The circuit board includes a wiring pad which is divided into a plurality of sub-pads by bubble discharge paths, the bubble discharge paths intersect at a first point which is a geometric center of the wiring pad. By configuring bubble discharge paths with a shape of a straight line and as being intersected at the geometric center point of the wiring pad, the circuit board can discharge gas bubbles, generated when the wiring pad is soldered to a wiring terminal of other circuit board, from the geometric center point of the wiring pad to the edge thereof via the bubble discharge paths. Thus gas bubbles can be eliminated or reduced between the wiring pad and the wiring terminal when soldering, connection between the wiring pad and the wiring terminal can be more secure.

Abstract: A pixel circuit includes a light-emitting device, a reset circuit, a write circuit, a compensation circuit, a light emission control circuit, and a drive circuit. The compensation circuit is configured to selectively transfer an uncompensated reference voltage or a compensated reference voltage to a third node, the compensated reference voltage being determined by the uncompensated reference voltage and a compensation voltage, the compensation voltage being related to a rated value of a power supply voltage. The light emission control circuit is configured to transfer a voltage at the third node to a first node to cause a change in voltage at the second node. The drive circuit is configured to control a magnitude of a drive current flowing through the light-emitting device based on the voltage at the second node and the power supply voltage.
