Electromagnetically controlled display device

Abstract

The present invention provides a display device that can replace patterns manually, does not consume canvas, is convenient to transport and install, low in price, low in energy consumption, natural and comfortable in light, and adopts electromagnetic control. The technical solution adopted is: The outer surface of the wall is coated with several groups of ring-shaped color layers in order, and several groups of soft magnetic electromagnetic coils are wound around the hollow tube and correspond to the positions of the ring-shaped color layers one by one. The direction of the magnetic field of the fixed magnet electromagnetic coil in the fixed magnet is the same or opposite, so as to control the moving position of the moving soft magnet in the hollow tube, and then affect the reflection position of the reflective material layer on the outside of the moving soft magnet to the incident light, so that the electromagnetic color can be displayed The color of the tube is changed, and the purpose of displaying the pattern is realized through an array of several electromagnetic color display tubes.

Description

technical field [0001] The present invention relates to display devices using electromagnetic control. Background technique [0002] Current display devices are divided into self-luminous display devices and reflective display devices. Self-luminous display devices use self-luminous methods to display patterns, such as LED displays, liquid crystal displays, plasma displays, projectors, etc. Self-luminous display devices have The advantages of fast response and good image effect, but there are the following defects: 1. The device is expensive and requires a lot of power consumption; 2. Under strong outdoor light, more expensive light sources and electric energy are required; 3. Self-illumination The light is unnatural and uncomfortable for human eyes. A reflective display device is a reflective display device, such as a three-flap panel. Reflective display devices have the advantages of being more natural and friendly than self-luminous display devices. The three flaps o...

[0002] Current display devices are divided into self-luminous display devices and reflective display devices. Self-luminous display devices use self-luminous methods to display patterns, such as LED displays, liquid crystal displays, plasma displays, projectors, etc. Self-luminous display devices have The advantages of fast response and good image effect, but there are the following defects: 1. The device is expensive and requires a lot of power consumption; 2. Under strong outdoor light, more expensive light sources and electric energy are required; 3. Self-illumination The light is unnatural and uncomfortable for human eyes

The three flaps of the reflective display device use the hinge to flip the triangular prism to realize the pattern transformation, which has the advantage of low cost, but in practical application, we found that there are still the following defects: 1. The three flaps can only display 3 patterns at most; 2. The pattern of the three flaps depends on the inkjet canvas, so the canvas needs to be consumed every time the pattern is changed; 3. The pattern of the three flaps needs to be replaced manually; 4. For super large screens, transportation and installation are very troublesome; 5. Requires an external light source at night

In addition, self-luminous display devices and reflective display devices each have their own advantages and disadvantages, and there is currently no display device that combines the two.
