Barco NV | Date: 2017-02-08

The invention provides a light beam projecting arrangement comprising: a first cluster of light sources arranged to provide a first cluster of light beams having a first etendue and a second cluster of light sources arranged to provide a second cluster of light beams having a second etendue, and means for changing the direction of the first cluster and/or the second cluster of light beams; wherein the light sources are arranged so that the total etendue of the first cluster of light beams is substantially equal to the etendue of the second cluster of light beams; and wherein the means for changing the direction are arranged so that the clusters of light beams are brought into a combined cluster light beam having substantially the same etendue as the larger one of the first etendue and the second etendue.

The present invention relates to methods and devices for sharing a presentation, allowing the presenter to capture and archive key elements of a meeting (KEMs) such as image frames for storage and later retrieval. The capture may be done via a device connected to one of a plurality of screens. The invention also allows the presentation to be followed on a personal device such as a smart phone, which can also access archived KEMs.


An immersive display system is disclosed that includes screens configured to mitigate reduction in contrast ratio due at least in part to peripheral light incident on the screens. The immersive display system includes at least two screens and at least two projector systems. The screens have a multi-layered structure configured to selectively reflect light in narrow wavelength bands. Each screen is configured to strongly diffusely reflect light in narrow wavelength bands that are different from the wavelength bands reflected by other screens in the immersive display system. Projector systems can be configured to provide light to associated screens in the narrow wavelength bands reflected by those screens.


The invention relates to a method for reducing imaging artefacts during a frame-changeover from a current frame to a following frame displayed by a display device comprising a plurality of pixels, wherein the artefacts are reduced by overdriving at least one control signal for controlling the pixel intensity of the related pixel during the frame-changeover, wherein the overdrive is carried out in dependence of the magnitude of an intensity step between a designated start intensity value of the pixel within the current frame and a designated target intensity value of the pixel within the following frame.


An immersive display system is disclosed that includes screens configured to mitigate reduction in contrast ratio due at least in part to peripheral light incident on the screens. The immersive display system includes at least two screens and at least two projector systems. The screens have a multi-layered structure configured to selectively reflect light for controlled periods of time. Adjacent screens can be configured to selectively reflect light during different periods of time. The projector systems can be configured to project video onto their respective screens while the associated screen is configured to selectively reflect light rather than absorb light.

A tile and a tiled display system is described comprising at least two adjacent tiles each having a display screen with display pixels which are picture elements, whereby for coloured displays each pixel is comprised of a plurality light emitting (e.g. LED) or light modulating (e.g. LCD),elements (e.g. RGB - see Fig. 1) each of the tiles having at least one first substrate of a first material and at least one first layer of a second material fixed to the first substrate characterized in that the thickness of the at least one first layer is less than the thickness of the first substrate; the coefficient of thermal expansion of the first substrate is less than the coefficient of thermal expansion of the at least one first layer and the distance between the at least two tiles is less than the size of a pixel on the display screen. The first substrates of adjacent tiles can be brought in mechanical contact with each other in order to reduce the seam between tiles to the minimum possible.


An immersive display system is disclosed that includes screens configured to mitigate reduction in conrast ratio due at least in part to peripheral light incident on the screens. The immersive display system includes at least two screens and at least two projector systems. The screens have a multi-layered structure configured to selectively reflect light in a tailored polarization state. Adjacent screens can be configured to selectively reflect light in orthogonal polarization states. The projector systems can be configured to project video onto their respective screens with light in a suitable polarization state. The screens can be further configured to selectively reflect light within a plurality of tailored spectral bands, the spectral bands being different for respective screens.

A touchscreen display system is described that has a touchscreen display (10) comprising an active area (11) and an user-input area (1), a touchscreen controller (4) and an auxiliary controller (5) the active are (11) and the user-input area (1) being connected to the touchscreen controller (4) and to the auxiliary controller (5), wherein a part of the active area (11) comprises at least one test area (3) allocated for test operations. Instructions are provided to assert the test areas to states of validated touches, a response signal is provided relating to the coordinates corresponding to the validated touches, and the signal is compared with the initial instruction.


A system and method are described so that participants of a phone conference can share electronic data, such as an online presentation, without a need to exchange passwords to link two devices together for data transfer nor go through a login procedure to access the data resource. Systems and methods of the present invention are more resistant to eavesdropping. The present invention provides methods, devices and systems to easily and automatically find, identify and authenticate one another on a computer network for electronic data exchange such that this process of setting up such an additional communication channel is reduced to a simple push user action. To achieve this, the participants use a device or software application that samples the audio of the phone conversation and creates a stream of audio fingerprints. The streams of fingerprints are sent to a matching service on the internet. This matching service finds the fingerprints that correspond to the same conversation among the streams of simultaneous users. Once a match is found with a high enough confidence level, the matching service exchanges identifiers such as public IP addresses and sends those back to the fingerprinting units. When instructed by the user, the units can then proceed to setup a secure data connection optionally using a cryptographic protocol and exchange electronic data in a secure way. This method avoids a cumbersome connection and authentication phase, and is thus easy to use, without requiring the existence of a user database and while still guaranteeing confidentiality and protecting the privacy of users.

A curved projection screen is described comprising a one-piece seamless substrate having a three-dimensional curvature. Said screen is arranged for being bent to a certain degree around one of its axes so that the smallest deformation of the screen is elastic, wherein the edge of said screen has been shaped so that its deformation during the above mentioned degree of bending is also elastic.
