Abstract: A current control circuit for LED or OLED sub-pixels or pixels of an active matrix display is able to store bits or a bit of a control signal used to drive a pixel or sub-pixel, in a memory associated with each pixel or sub-pixel. The control circuit elements can be made compatible with thin-film processing such as to produce thin-film transistors.

Abstract: A light emitting module for a light emitting display, including a first backplane and a third backplane arranged in a stackup. The first backplane includes a thin film transistor (TFT) layer deposited on a first substrate, the TFT layer further including a plurality of light emitting elements, associated contact pads and conducting tracks. The third backplane is provided on top of the light emitting elements, includes cavities at the locations of the light emitting elements and includes at least a ground layer and a power layer. The upper and lower layers of the third backplane are provided by alternatively the ground layer and the power layer for contacting the light emitting elements.

Abstract: A driver circuit for driving a matrix of N×M pixels of a light emitting module. Each pixel is composed of at least three types of light emitting elements. The light emitting elements are driven by a modulation control signal. The driver circuit is embedded in a TFT layer. It is configured to cooperate with N multiplexers provided in an external driver circuit, each multiplexer being configured to drive one line of M pixels. It is also configured to cooperate with one external current source per type of light emitting element, each external current source being mirrored M times on the matrix of the driver circuit and being arranged in series with a signal switch for generating the control signal provided for each of the M columns.

Abstract: A light emitting module including a first surface having a plurality of light emitting elements, a second surface configured to receive driving signals and to transfer these signals to the light emitting elements of the first surface. The second surface includes a plurality of optical transmitters, in which the optical transmitters are each associated to an associated optical receiver arranged on the first surface, the optical transmitter and the associated opposing optical receiver being separated by an optical medium, such that an optical signal including driving signals transmitted by the optical transmitter is received by the opposing optical receiver, each optical receiver being connected to at least one light emitting element and is configured to transform the optical signal into an electrical signal configured to drive the at least one light emitting element to generate an image on the display.

Abstract: A display panel (65) and a method for manufacturing a display panel (65) that includes a front side and a back side, the display panel (65) including a substrate having a plurality of electrical components provided on a front side of the substrate and integrated circuits connected to the plurality of electrical components, the integrated circuits being embedded in the substrate. A plurality of edge contacts (54, 62) is also provided along edges of the substrate, where the plurality of edge contacts (54, 62) is electrically connected with the integrated circuits. An electrically conductive layer (51, 61) covers at least a part of the front side of the substrate and surrounds the plurality of electrical components, where the electrically conductive layer (51, 61) does not physically contact the embedded integrated circuits and provides EMI shielding to different components of the display panel (65).
