Driver circuit for light emitting module with combined active and passive matrix functionality

The present invention relates to a driver circuit for driving an N * M pixel matrix of a light emitting module, in which each pixel consists of at least three types of light emitting elements. The light emitting element is driven by a modulation control signal. The driver circuit is embedded in the TFT layer. The driver circuit is configured to cooperate with N multiplexers disposed in an external driver circuit, each multiplexer configured to drive one M pixel line. The driver circuit is also configured to cooperate with one external current source of each type of light emitting elements, each external current source mirroring M times on the matrix of the driver circuit and arranged as a series signal switch for generating a control signal provided for each of the M columns. 本发明涉及一种用于驱动发光模块的N×M像素矩阵的驱动器电路，其中，每个像素由至少三种类型的发光元件组成。该发光元件由调制控制信号驱动。该驱动器电路内嵌在TFT层中。该驱动器电路配置为与设置在外部驱动器电路中的N个多工器协作，每个多工器配置为驱动一个M像素线路。该驱动器电路也配置为与每种类型的发光元件的一个外部电流源协作，每个外部电流源在该驱动器电路的矩阵上镜像M次，并布置为串联信号开关，用于产生针对M列中每一列提供的控制信号。
