Abstract: A video voltage supplying circuit includes: a circuit that supplies high and low level voltages to a common electrode through a feed line. When positive polarity enables a pixel electrode in a voltage level higher than the common electrode, the low level common voltage is supplied, and when negative polarity enables the pixel electrode in a voltage level lower than the common electrode, the high level common voltage is supplied. A circuit connected to a video supply line is supplied with high and low level video voltages. When the voltage is applied to the scan line, the circuit supplies the high or low level video voltages to a pixel based upon designation of white display or black display and designation of written polarity. A video voltage supplying circuit generates an offset voltage to supply the video voltage by offsetting the common voltage by a predetermined voltage in a predetermined direction.

Abstract: There is offered a Gray code counter with which a delay time of a critical path is reduced and a fast operation is made possible. A first Gray code bit Q0 is obtained by outputting an output signal Q0o of an RDFF 2 through an RDFF 31 to synchronize with a clock CLK. A second Gray code bit Q1 is obtained by outputting an output signal Q1o of an RDFF 2 through an RDFF 32 to synchronize with the clock CLK. A third Gray code bit Q2 is obtained by delaying an output signal Q2o of an RDFF 4 with a selection circuit 21 and outputting it through an RDFF 33 to synchronize with the clock CLK. A fourth Gray code bit Q3 is obtained by delaying an output signal Q3o of an RDFF 5 with an AND circuit 11 and a selection circuit 22 and outputting it through an RDFF 34 to synchronize with the clock CLK. Higher bits of the Gray code are similarly generated.

Abstract: A semiconductor light emitting device includes at least two semiconductor light emitting elements which emit different colors of light to each other. The device further includes a lead frame for supporting the light emitting elements and a resin molding for sealing these elements. The external form of this resin molding is an ellipsoid or a part of an ellipsoid in which the curvature in the perpendicular direction to the element row is designed to be smaller than that in the parallel direction to the row. As a result, the device has a widely spread mixed color range especially in the perpendicular direction to the element row and high luminous intensity especially in the parallel direction to the element row. So, a multicolor light emitting device having a high ability of color mixture as well as high luminous intensity can be obtained.
