pixelschaltung to zeitmultiplexansteuerung of unterpixeln in an oled color

摘要

The invention relates to a display device which comprises a plurality of scanning lines for transmitting selection signal, a plurality of data wires for transmitting data signal and a plurality of pixel circuits connected to the scanning lines and the data wires. Wherein at least one pixel circuit comprises a first capacitor for charging a voltage corresponding to a data signal transmitted from adata line, a first transistor for outputting the current corresponding to the voltage charged in the first capacitor, a first, second and third emission elements for lightening corresponding to the current outputted by the first transistor; and a first, second and third emit control transistors which are respectively between the first transistor and the first, the second and the third emit elements. Wherein the first semiconductor layer forming the first emit control transistor and the second semiconductor layer forming the second emit control transistor are usually symmetrically arranged corresponding to the third semiconductor layer forming the third emit control transistor.
