Each picture dot includes an organic diode and first and second driver circuits for the diode. Each of the first and second driver circuits includes a driving transistor connected between a reference voltage and one electrode of the diode, a switching transistor for switching a gate voltage onto a gate of the driving transistor, and a capacitor connected to the gate of the driving transistor.

摘要： A video system including a sequential color liquid crystal display with a panel of pixels arranged in rows and columns, including a mechanism that controls unit brightness levels on each pixel in the panel called grey levels, each grey level corresponding to a video information received at the input. The grey level controlled on a pixel is achieved with an analog voltage that varies monotonously depending on the row associated with the pixel and/or a color to be displayed.

摘要： A shift register, each stage thereof provided to drive a corresponding output line, includes an output transistor that drives the output line and an additional transistor of the same technology and of the same polarity as the output transistor. The additional transistor is connected in such a way as to be subject to bias conditions similar to the output transistor, such that the additional transistor's threshold voltage, identical at the start of life to that of the output transistor, drifts as quickly or more quickly as the threshold voltage of the output transistor. The additional transistor is used to adjust the precharging voltage of a gate of the output transistor to its conduction performance characteristics during the precharging and/or selection phase.

摘要： The present invention relates to a process for displaying data on a matrix display consisting of N data lines and P selection lines at the intersections of which are situated the image points or pixels. The N data lines are grouped into {dot over (P)} blocks if N′ lines where N={grave over (P)}×N′. Each block receives in parallel one of the P′ data signals which is demultiplexed on the N′ lines of the said block. The scanning of the N′ data lines of a block is carried out from 1 to N′ or from N′ to 1, alternately, according to the selection lines.

摘要： An integrated method of detecting an image defect in an LCD screen consists in verifying the consumption of current on a power supply bus of the image display means (row driver 20, column driver 30, counter electrode CE), during capacitive charges or discharges of the selection lines Li and/or columns ColRj. The method comprises the integration of a current measurement chain comprising a measurement resistor Rm on the power supply bus and measurement 41 and comparison 42 circuits providing outside the screen a detection signal Sd which is processed by an external circuit for safety management.
