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).

Abstract: A filter, having a first filter material and second filter material, the first and second filter materials having different light attenuation properties and being in mutual contact along an interface surface, a cross-section of which has a curved line. Additionally, a method for preparing a filter, by: combining a first surface and an element to form a moulding cavity, delimited by the surface and by a moulding surface of the element; inserting a first material in liquid state; allowing the first material to solidify; removing the element to form a second moulding cavity, delimited by a second part of the surface and by the solidified first material; and inserting a second material in the second moulding cavity.

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 device for elastic pivoting about two orthogonal axes as well a method of manufacturing thereof using additive manufacturing processes. The device can be used in a projector, such as a back projector, a scanner such as a laser scanner, or other forms of displays, or a telescope etc. The device includes an inner frame and an outer frame. First and second flexible spring elements extend out of the plane in which the inner frame lies and third and fourth flexible spring elements extend out of the plane in which the outer frame lies.

Abstract: A reflective display device and a method of making or operating the display device, where the reflective display device includes a spatial reflective light valve, at least one light emitting element being positioned in front of the spatial reflective light valve and light shaping device to direct the light generated by the at least one light emitting element in defined directions with respect to the spatial reflective light valve. This makes use of the fact that the contrast improves and the diffuse reflection component of the reflective display increases when the illumination direction gets closer to the perpendicular direction but rays close to the perpendicular direction need to be reduced in intensity or better still avoided to reduce the specular component. This can use illumination directions close to the perpendicular direction while preventing or reducing specular reflection within a range of incident angles.
