Embodiment Construction

[0055] According to the present invention in its entirety, an electronic control unit for an organic light emitting diode (OLED) of a pixel / segment in an active matrix display comprises a matrix set of such units. This display mechanism operates sequentially in time units, each time unit corresponding to the duration of the frame display. Throughout the frame duration, the columns or rows of the matrix are scanned to enable the display configuration (off or on level / intensity) for each pixel / segment. The OLED of a pixel / segment is supplied by a control circuit which operates as an electronic switch with respect to a control signal arriving via a control line and causes or disables the flow of a current of variable magnitude in the OLED, which is connected between the ground line and the power supply. Terminal V dd obtained between.

[0056] The leadthrough impedance (resistance) of the control circuit in the on-state is relatively small in order to turn on the OLED and avoid...

Abstract

The invention relates to an electronic control cell for at least one organic electroluminescent diode (OLED) of a pixel or segment of an active matrix display, wherein the cell comprises at least one control circuit (6,61,62) with a control input and functioning according to a control signal arriving on a control line (5,5') and enabling the OLED(s) to be switched on or not, a capacitative storage memory for the control signal whereby the capacitor thereof is linked to the control line, a selection circuit (4,41,42) functioning according to a selection signal Vsel on a selection line (3,3'), enabling the capacitative storage circuit to be linked to or to be insulated in relation to a control voltageVcom, (2) according to the selection signal. According to the invention, storage is temporary by discharging the capacitor via a resistor Rf parallel to the capacitor. The invention also relates to operating methods and a display.

Description

technical field [0001] The invention relates to an electronic control unit for organic light-emitting diodes in an active matrix display and a method of operation, which can be applied in the field of display units, in particular flat screens, wherein the basic display unit with organic light-emitting diodes, i.e. a pixel Or segments are respectively controlled by control units arranged in the form of one or several matrices. Background technique [0002] The development of electronic equipment and / or industrial data processing equipment or public equipment requires the use of interfaces to interact with users, especially visual interfaces with display mechanisms or field or pixel monitors. These four terms are considered in pairs below. same meaning. In order to provide enhanced display performance, it is presently preferred to act on the display elemental structures (segments or pixels) individually, thus display structures with active matrices have been developed.
