Display device with local compression and decompression of displayed digital data

A display device including at least:

• an array of display blocks, each display block being configured to display at least one pixel of an image and comprising several lighting elements and at least one drive circuit configured to generate control signals for the lighting elements of the display block from digital data intended to be displayed by the lighting elements of the display block;
• an array of control circuits, each coupled and associated with at least one display block and including a first main memory circuit configured to store the digital data intended to be displayed by the lighting elements of the associated display block;
• a video card comprising at least one input configured to receive a digital signal to be displayed by the array of display blocks, and at least one output of digital data coupled to the array of control circuits by a data distribution circuit, the video card being configured to decode the digital signal and send to the control circuits the digital data intended to be displayed by the lighting elements which are derived from the digital signal received by the video card and encoded in a format adapted to the array of display blocks;
• and wherein:
• the video card includes at least one compression circuit configured to compress, before sending them to the output, the digital data intended to be displayed by the lighting elements;
• each control circuit includes a decompression circuit configured to decompress the digital data intended to be displayed by the lighting elements of the display block associated with the control circuit before storing them in the first main memory circuit of the control circuit.
