Visual display unit for processing a double input signal

An electroluminescent display unit (1) comprising:

• a matrix of electroluminescent pixels (38) formed from a plurality of pixels arranged on a substrate, according to a matrix arrangement in lines and columns, each pixel being formed by at least one elementary emitting zone (225,325,425);
• a first control block (2) configured to control a graphic and/or alphanumeric data stream that can be displayed on said matrix of pixels (38);
• a second control block (3) configured to control a video data stream that can be displayed on said matrix of pixels (38), said video data stream being refreshed periodically;
• a unit (4) for generating a reference voltage,
• knowing that said data stream may be static and reprogramed as required, or refreshed periodically with a refresh frequency independent from same of said video data stream,
• said unit (1) being characterized in that:
• each elementary emitting zone is connected to a static memory, addressed by said first control block (2), and to a dynamic memory, addressed by said second control block (3);
• said first (2) and second (3) control blocks are configured to be able to display data alternately or simultaneously on the same matrix of pixels (38).
