    Abstract: A driver circuit for driving a matrix of N x M pixels of a light emitting module, wherein 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 display panel having a frontside and a backside with electrically conductive tracks that are able to be connected with an electrically conductive member along the display panel (or substrate) short edge for connecting electrical components on the front side and the backside of the display panel. The electrically conductive tracks and the electrically conductive member can be interfaced with conductive bumps, which are located on an outside surface of the display panel and arranged to electrically connect the electrically conductive track on the substrate to the electrically conductive member. Additionally, an alignment tool for assembling multiple display panels that can have different inclination of their front surfaces, e.g., the average plane of the light sources, where the alignment tool can align the front surfaces of all display panels to lie within the same plane.
