Abstract:
1. Display screen including: light emitters arranged as rows of light emitters and columns of light emitters to form an array of light emitters, a silicon substrate on which control means to control the emissions of the light emitters are fabricated, the said control means including: wherein a single compensating transistor is connected to all the modulation transistors of a given column and is intended to compensate for the trigger voltages of all the said modulation transistors of this column, wherein said compensating transistor of a given column is formed in the geometrical extension of the line-arrangement of the said modulation transistors of said given column along said same guiding line, wherein said modulation transistors and said associated compensating transistor are fabricated on a polycrystalline silicon substrate obtained by heating an amorphous silicon substrate, using a laser beam, said beam being intended first to heat a first rectangular heating surface of the substrate then to move in a direction of movement and then to heat a second rectangular heating surface, and wherein said modulation transistors associated with the light emitters of a given column and the associated compensating transistor are aligned in one and the same heating surface, the guiding alignment line extending approximately perpendicularly to the direction of movement of the laser beam.
