<p>The present invention relates to the light-emitting and LED based display modules. The light emitting module comprises a plurality of electrically connected light emitting elements depicting pixels and a main controller that allows the output, to a light emitting module, of a dynamic and static image from a source of a video signal. Also provided is at least one signal and power distribution board, connected to the main controller and the above mentioned light emitting elements, which supply power and transmit data signals. The signal and power distribution boards, adopted for sequential transmission of the data signal with amplification of the level and correction of the pulse fronts, are provided with drivers and programmable holding registers. Thereby said boards distribute a high-frequency data signal between several light-emitting elements and change a rate feedback signal by means of going-down the frequency of the data transmission, depending on the length of a conductor connecting the light emitting elements. These bias in time range between the desired values the data packets for the general synchronization, hence, the alternating light emission is provided to only the required light emitting element, with the desired intensity and at the predetermined unit of time. Optionally - also a desired color. The module further comprises at least one switching unit, connected to the main controller and the signal and power distribution boards, which supplies the electric power and data signal from the main controller to the signal and power distribution boards, or groups of such boards.</p> |
