ORGANIC LIGHT-EMITTING DIODES BASED DISPLAY UNIT, METHOD OF ITS EXCITATION AND DISPLAYING DEVICE Russian patent published in 2018 - IPC G09G3/3208 H01L27/32 

FIELD: images forming devices.

SUBSTANCE: invention relates to the organic light-emitting diodes based display devices. Technical result is achieved due to the fact that the sub-pixel blocks contain OLED structures and the pixel circuits in the same pixel block are correspondingly connected to the different data signal lines; pixel blocks are pixel blocks, each with the multi-layer structure, and each includes two adjacent multi-layer groups of sub-pixel blocks, each of which includes sub-pixel blocks, which have different emission colors, are arranged in layers and are isolated from each other, and the number of sub-pixel blocks in each sub-pixel blocks multilayer group of the same pixel block with the multilayer structure is the same; in each pixel block with the multilayer structure, two located in the same layer sub-pixel blocks, form the sub-pixel blocks layer; and in the same pixel block with the multilayer structure, only one layer of the sub-pixel blocks includes two sub-pixel blocks, which have the same emission color.

EFFECT: technical result consists in improvement of the OLED display unit pixel mapping quality.
