Abstract
Active matrix display screen and processes for making it. The sources of transistors Tij controlling the display points belonging to a line Li are connected to the following line Li+1 by a resistive strip Bij and a conductive bridge Kij. If a transistor is defective and short-circuited, this defect does not affect the adjacent transistors.
Claims7
Active matrix display screen comprising a first plate on which are deposited conductive blocks (Pij), control transistors (Tij) having a drain (D), a gate (G) and a source (S) and addressing conductive lines (Li) able to be connected to a line control circuit (CCL), the gates (G) of said transistors (Tij) being connected to said addressing lines (Li) and the drains (D) to said blocks (Pij), a second plate comprising addressing conductive columns (Cj) covering said blocks (Pij) of the first plate, and a liquid crystal inserted between said first and second plates, said screen being characterized by the fact that the source (S) of said transistor (Tij) whose gate (G) is connected to said addressing line (Li) of position i is connected to the adjacent addressing line (Li+1) of position i+1 by a resistance (Rij).
