Abstract

FIELD: optics; displaying information.

SUBSTANCE: electromechanical pixels of the display contain three electromechanical subpixels, which are disk-light filters that transmit light of one of the three wavelengths R - red, G - green, B - blue with black sectors and magnetic stipes applied to them. The filter disks are located in the liquid in the triad of matrix holes and rotate freely in the plane of the matrix. The matrix is closed on both sides with protective films. Transparent addressable electrodes are formed and applied on the front protective transparent film, passing over each filter disk and having the same opaque sectors as on the filter disks themselves. There is a light guide layer between the rear protective film and the matrix; and a reflective surface is applied on the rearmost protective film, on the side of the matrix.

EFFECT: simplified design, increased reliability and strength of the device.

Description

The invention relates to the field of optics and means of displaying information and can be used to create a color image on thin, flexible display screens that do not contain an LCD matrix.

The invention is new, since from the prior art, according to available sources of information, no analogues with a similar set of features have been identified.

The technical result of the claimed invention is to improve the main performance characteristics of displays, simplify the design, improve the manufacturability of the production process, as well as increase the reliability and strength of the device. It becomes possible to create the thinnest screens for TVs, tablets, smartphones, electronic paper, etc., capable of bending, which will be much less susceptible to damage from shock and deformation.

The invention is industrially applicable as it can be used in all areas where thin, flexible display screens are required.

This technical result is achieved in that the electromechanical pixel 1 (Fig. 1), consisting of three electromechanical subpixels 2 (Fig. 1), contains a thin, flexible opaque matrix 3 (Fig. 1, Fig. 2), with triads of holes and located in them with magnetized disks light filters 4 (Fig. 3), thinner than the matrix and transmitting light of one of three wavelengths: R - red, G - green, B - blue, freely rotating in the plane of the matrix and located in the liquid 10 (Fig. 2) , to reduce friction. Opaque black sectors 14 (Fig. 3) and a magnetic stripe 11 (Fig. 3) are applied on the filter discs. The matrix is closed on both sides with protective films 5 and 7 (Fig. 2). On the front translucent protective film 5 (Fig. 2) from the side of the matrix 3 (Fig. 2), opposite the filter discs

4 (Fig. 2), the same opaque black sectors 8 (Fig. 1) are applied as on the filter discs 4 (Fig. 3) black sectors 14 (Fig. 3), and also transparent address electrodes 9 (Fig. 1) passing through these black sectors 8 (Fig. 1). Between the matrix 3 (Fig. 2) and the rear protective film 7 (Fig. 2) there is a light guide layer 6 (Fig. 2) for illuminating the filter disks 4 (Fig. 2,). On the rearmost protective film 7 (Fig. 2), from the side of the matrix, a mirror-reflecting surface 13 is applied (Fig. 2).

The invention is illustrated by drawings, which do not cover, and even more so do not limit the entire scope of claims of this technical solution, but are only illustrative materials of a particular case of execution.

On FIG. 1 shows an electromechanical pixel in general view.

On FIG. 2 shows an electromechanical pixel in section.

On FIG. 3 shows a filter disk.

The electromechanical pixel contains a matrix 3 (Fig. 1, Fig. 2) with electromechanical subpixels 2 located in it in a triad of holes (Fig. 1). Representing disk filters 4 (Fig. 3) transmitting light of one of three wavelengths: R - red, G - green, B - blue. They are coated with opaque black sectors 14 (Fig. 3), as well as a magnetic stripe 11 (Fig. 3). Filter discs 4 (Fig. 2) are in liquid 10 (Fig. 2). Matrix 3 (Fig. 2) is closed on both sides with protective films 5 and 7 (Fig. 2). On the protective film 5 (Fig. 2), from the side of the matrix 3 (Fig. 2), control transparent electrodes 9 (Fig. 1) are applied, and opposite the discs of light filters 4 (Fig. 2), the same opaque black sectors 8 are applied (Fig. 2). 1) as well as on the filter disks 4 (Fig. 3) black sectors 14 (Fig. 3). On the rear protective film 7 (Fig. 2), from the side of the matrix 3 (Fig. 2), a mirror-reflecting surface 13 is applied (Fig. 2). Between the matrix 3 (Fig. 2) and the rear protective film 7 (Fig. 2) is the light guide layer 6 (Fig. 2).

The electromechanical pixel works as follows: when a certain voltage is applied to the transparent address electrodes 9 (Fig. 1), passing over the given magnetic disks of the light filters 4 (Fig. 2, Fig. 3), the electromagnetic field of the electrodes interacts with the magnetic field of the magnetic strip 11 ( Fig. 3) on the filter disks 4 (Fig. 2, Fig. 3) will make them rotate through a certain angle, depending on the magnitude of the applied voltage, closing or opening the transparent colored sectors. Thereby adjusting the amount of light passing through them. When the black sector 14 (Fig. 3) on the filter disk 4 (Fig. 2, Fig. 3) and the black sectors 8 (Fig. 1) on the film 5 (Fig. 2) are aligned, the electromechanical subpixel is fully open and transmits the maximum amount of light. When the black sectors are completely misaligned, the electromechanical subpixel is closed and does not transmit light. Due to the color combinations on the electromechanical subpixels, each electromechanical pixel will glow with the desired color and thus the required image will be displayed on the matrix. When the voltage is removed, the filter discs will remain in the same position, without requiring electricity. When the polarity of the voltage is reversed, the filter disks rotate in the opposite direction and when the voltage is removed, they will also remain in the same position. Through the light guide layer 6 (Fig. 2) is illuminated disks of light filters 4 (Fig. 2, Fig. 3).

The use of this invention will make it possible to create thin, flexible, reliable and durable display screens, simplify the design, and also increase the manufacturability of the manufacturing process.
