Abstract

A laser projection apparatus and a laser projection display method are provided. The laser projection apparatus includes a laser source, an optical engine, a projection lens, and a power system architecture. The power system architecture includes a digital light processing (DLP) control processing portion. The DLP control processing portion is configured to: output a first enable signal and a first luminance adjustment signal to a laser driver circuit and a first drive signal to a digital micro-mirror device, in the first period; output a second enable signal and a second luminance adjustment signal to the laser driver circuit and a second drive signal to the digital micro-mirror device, in the second period. The laser driver circuit is configured to: drive a laser array to emit a primary color beam in the first period, and drive the laser array to be turned off in the second period.
