Abstract
The present disclosure relates to an OLED pixel circuitry, a driving method thereof and a display device. The OLED pixel circuitry includes: a driving circuit, a light emitting circuit and a short-circuit protection circuit, wherein the driving circuit is coupled to a scan signal input terminal, a data signal input terminal, a first voltage terminal and the light emitting circuit respectively, and is configured to drive the light emitting circuit to emit light; the light emitting circuit is further coupled to a second voltage terminal, and is configured to emit light; and the short-circuit protection circuit is coupled to the driving circuit and the light emitting circuit, and is configured to control the driving circuit to be turned off when a short circuit occurs in the light emitting circuit.
