FLAT PANEL DISPLAY MATRIX ELEMENT Russian patent published in 2010 - IPC G02F1/00 

FIELD: physics.

SUBSTANCE: matrix element includes a micro white light-emitting diode, an opaque housing with three identical cells inside, each having a colour filter of one of the primary colours R, G, B, a microlens, from the first to the eighth micro piezoelectric elements and an output microlens. One end of each micro piezoelectric element is rigidly attached to the wall of the housing. Each cell of the matrix element includes from the first to the eighth neutral micro colour filters arranged in series on the optical axis of the macrolens, each connected to its micro piezoelectric element such that the free ends of the piezoelectric elements are connected to neutral colour filters. Each micro colour filter can attenuate radiation in proportion to its absorption coefficient.

EFFECT: reliable colour transfer of the matrix element due to change in the principle of converting code to radiation luminance in cells.
