Abstract
Disclosed is a passive display apparatus. The passive display apparatus includes multiple light-emitting elements, a scanning circuit, multiple scanning switches, and a current control circuit. The light emitting elements are arranged in an array. The scanning circuit is coupled to the light-emitting elements and has multiple scan shift registers to generate multiple scan signals enabled sequentially. The scanning switches receive the scan signals and a first operating voltage to provide the first operating voltage to the light-emitting elements row by row. The current control circuit is coupled to the light-emitting elements, and receives multiple pixel voltages to provide multiple light-emitting currents to the light-emitting elements. The light-emitting elements emit light based on the received light-emitting currents.
