Abstract
The invention provides a chip structure of a micro light-emitting diode display, comprising a package substrate, at least one light-emitting diode (LED) element, at least one metal oxide semiconductor field effect transistor (MOSFET), and a connection line. The LED element and the MOSFET are positioned on the package substrate, and each MOSFET comprises a source connected with the input voltage in common, a gate connected with a main control circuit, and a drain. An end of the LED element is connected with the drain of the MOSFET through the connection line, and the other end of the LED element is independently connected with a source drive circuit. Therefore, the MOSFET is provided on the package substrate and integrated in a chip structure, so as to achieve a better heat dissipation effect and requirements of high density and brightness.
