ЭЛЕКТРОМАГНИТНАЯ СИСТЕМА ПРИВОДА ДИСПЛЕЙНОГО ПИКСЕЛЯ

摘要

New technical solution of the electromagnetic display pixel driving system solves the problem of switching the display pixel flap between two bistable »ON« and »OFF« positions. The magnetic circuit of the display pixel consists of a permanent magnet (2c) in the display pixel flap (2) and an electro-magnet (5+3u) with a magnetic core (3u). Said permanent magnet (2c) is made using an injection molding process and is divided in two areas with antiparallel direction of magnetization, which is also perpendicular to the flap's surface (2a, 2b) and pivoting axis (2d). Electro magnet (5+3u) is placed under the flap (2) and has a preferably U shaped magnetic core (3u), which is oriented parallel to the pivoting axis (2d). This design minimizes the stray magnetic field and interactions between neighboring display pixels.
