Abstract

The invention discloses an MEMS (Micro Electromechanical System) switching device, an array substrate, a manufacturing method of the array substrate, a display device and a driving method of the MEMS switching device. The display device can be flexibly switched among a transmission mode, a reflection mode, a reflection mode and a semi-transmission and semi-reflection mode to meet display requirements of different scenes. The MEMS switching device comprises a light valve element and a switching element, wherein the light valve element comprises a first induction electrode perpendicular to light transmission direction, a second induction electrode parallel to the light transmission direction, an insulating layer covering the first induction electrode and the second induction electrode and insulating the first induction electrode and the second induction electrode, an anchoring part positioned at the junction of the first induction electrode and the second induction electrode and a moving grating connected with the anchoring part; the moving grating can reflect ambient light or light emitted by a front light source when forming an included angle with the second induction electrode; when electric field voltage is applied to the light valve element, the light valve element works in the transmission mode, the reflection mode or the semi-transmission and semi-reflection mode.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a MEMS (Micro-electromechanical System, micro-electromechanical system) switch device, an array substrate and a manufacturing method thereof, a display device and a driving method for the MEMS switch device. Background technique [0002] Liquid crystal display devices can be divided into transmissive, reflective and transflective according to different light sources used. Among them, the transmissive liquid crystal display device uses the backlight as the light source, which has the advantage that it can display bright images in a dark environment, but the disadvantage is that the light that can pass through accounts for a small proportion of the light emitted by the backlight, and the power consumption is high; reflection The type liquid crystal display device uses the front light source or the ambient light source as the light source, and uses metal or other material l...
