  • Patent number: 11984064
    Abstract: A display apparatus having a wide range of threshold voltage compensation function is provided. In the display apparatus, a p-channel transistor is used as a driving transistor of the light-emitting device. Discharging is performed through a source-drain path while constant voltage is supplied to a gate so that Vth is extracted between the gate and the source. In addition, when a drain potential is set to the sum of forward voltage and a cathode potential of the light-emitting device or a potential sufficiently lower than the sum, it is possible to continue the discharging even when Vth is positive voltage. That is, compensation can be performed even in the case where Vth variation occurs from positive voltage to negative voltage.

  • Publication number: 20240144879
    Abstract: Provided is a highly reliable semiconductor device. The present invention relates to a shift register circuit including a plurality of stages of sequential circuits. An output signal of a sequential circuit is input to a sequential circuit in the subsequent stage. Before a sequential circuit outputs a signal and after the sequential circuit outputs the signal, the potential of a gate of a transistor included in the sequential circuit is changed in accordance with a clock signal so as to avoid voltage stress application between the gate and a source of the transistor for a long time. The shift register circuit can be applied to a scan line driver circuit of a display apparatus, for example.

  • Patent number: 7509623
    Abstract: A pattern correction method executed by a computer includes a first correction and a second correction. The first correction is executed by calculating a correction value, in consideration for an optical proximity effect, for edges (first edges) meeting a condition among the edges constituting a designed pattern. Subsequently, The second correction is executed for an edge (second edge) which does not meet the condition, by use of the correction value of any one of the edges (first edges) adjacent to the second edge among the first edges for which the first correction is executed, thus connecting the corrected first edge and the corrected second edge by a line segment. The pattern is corrected to a shape suitable for a mask drawing and a check with simple processing.
