FIELD: physics.
SUBSTANCE: in the optoelectronic display in the housing, a liquid crystal display is placed; it displays information with a backlight located behind the liquid crystal display in the housing in front of the liquid crystal display parallel to its outer surface, further fixing the polarizing plate so that it can rotate about its optical axis within the angles 0-90°, The information displayed on the illuminated liquid crystal display illuminated from the light source is observed from the side of the polarization plate, the brightness of the information display on the optoelectronic display is controlled by rotating the polarization plate.
EFFECT: simplification of the procedure of creating optoelectronic displays with adjustable brightness of the display of information containing a liquid crystal display.
