Abstract
Disclosed are an LED direct-view projection array light-emitting module and a display screen. The light-emitting module includes a video decoding drive board, a display unit drive board, display units, and an imaging unit from the bottom up. The present disclosure uses a semiconductor technology to integrate and miniaturize light sources that emit light actively to obtain integrated LED array chips as light-emitting sources, directly controls the light-emitting sources through a circuit, then uses magnification objective lenses to perform a certain magnification according to an application scenario requirement, and then focuses on and image each pixel by using a focusing lens. Through a combination of the magnification lenses and the focusing lenses, when the light source intensity is sufficient, products of various sizes can be designed; when splicing into a large screen, splicing angles can be adjusted arbitrarily to realize a flexible screen or a special-shaped screen.
