PIXEL CIRCUIT AND DISPLAY UNIT Russian patent published in 2013 - IPC G09G3/294 G02F1/1368 

FIELD: medicine.

SUBSTANCE: pixel circuit (2) comprises: an internal assembly (N1) which maintains the pixel data voltage applied to a portion (21) of a display unit, a first switching circuit (22) which transmits the pixel data voltage supplied from a data signal line (SL) to the internal assembly (N1) via at least a switching element (T4), a second switching circuit (23) that transmits the voltage applied to a predetermined voltage supply line (VSL), to the internal assembly (N1) without passing through the switching element (T4) and a control circuit (24) that maintains the predetermined voltage according to the pixel data voltage maintained in the internal assembly (N1), one end of a first capacitive element (C1) and controls connection/disconnection of the second switching circuit (23 ).

EFFECT: lower energy consumption of the display unit causing no image format reduction.
