  • Apparatus and method for color shift compensation in displays
    Patent number: 8619016
    Abstract: Active matrix display module (10) comprising a driving circuit with a source driver (20) and a gate driver (12). Furthermore, a display panel (11) with pixels consisting of three sub-pixels is provided. The sub-pixels are arranged in rows and columns and each sub-pixel comprises a sub-pixel selection transistor arranged at an intersection of a row and a column. The gate driver (12) is employed to select and deselect all pixels of a row of the display panel (11) and the source driver (20) is employed for providing the required voltage levels to all sub-pixels of a currently selected row, said voltage levels corresponding to the desired intensity for each color. Demultiplexer switches (21) are integrated onto the display panel (11) for demultiplexing columns of the display panel (11). The active matrix display module (10) further comprises means (18) for color shift compensation. These means (18) implement a selection order for the selection of the sub-pixels to compensate unintentional color shifts.
