MATRIX DISPLAY WITH CONTROLLED EQUIVALENT AREA FOR DIFFERENTIATING CHARACTERS Russian patent published in 2011 - IPC G09G3/12 

FIELD: information technology.

SUBSTANCE: in the matrix display, digital format position elements are distributed on 9x9, 7x7, 5x5, 3x3, 1x1 format loops, illumination or black out of which causes change in the number of point elements therein, while maintaining, when formatting digital characters from 0 to 9, constancy of the number of point elements therein, which corresponds to the changed number of displayed point elements in the format loops, and the decimal point is displayed on the character either by blacking out or illuminating the 1x1 format loop depending on whether it is illuminated or blacked out when forming characters.

EFFECT: reduced power consumption irregularities from character to character owing to providing equal surface area of illuminated point elements of a character.
