摘要： A phase-locked signal generator which performs phase-locked control of the output of a triangular-wave VCO when a trigger signal is not inputted, and which performs, when the trigger signal is inputted, short interval suspension of oscillation of the triangular-wave VCO, and detection of a phase difference between the trigger signal and the reference clock signal by a successive phase measuring portion after the short interval by using the triangular-wave signal, thereby obtaining phase data. The measured phase data is held until the next trigger signal, and the phase of the triangular-wave VCO is controlled in accordance with the phase data so that the triangular-wave signal has a fixed phase with respect to the reference clock signal. A square-wave signal outputted from the triangular-wave VCO is used as the phase-locked clock signal. This makes it possible to generate the phase-locked clock signal at higher stability than a conventional circuit, and to improve jitter without using the multiplied frequency of the phase-locked clock signal.

摘要： A display device includes a display unit in which display elements provided with pixel circuits are arranged so as to have a sequence of three different colors in a row direction and the colors are shifted in a column direction by 1.5 columns. A scanning line is provided in every row of the display unit, a signal line is provided in every column of the display unit, and a column control circuit outputs a display signal for every column. The positions of the pixel circuits are displaced in the row direction with respect to the arrangement of the display elements, and are thus aligned in the column direction and also connected to the signal line only on one side of the signal line. No inversion of the pixel circuit pattern occurs and variations of the circuit characteristics in every row are suppressed.
