    Abstract: The invention pertains to a projector comprising an optical engine, a projection lens, a means for light deviation, and an afocal lens system, wherein the projector has a total throw ratio between 0.7 and 0.8. Such a projector can be used to build a very compact and cost-effective back-projection system. The invention also pertains to a projection assembly comprising such a projector, followed by a means for light gradation and a front-surface mirror. The invention also pertains to a display system comprising at least one such projection and a display screen.

    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.
