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.
