A DRIVE DEVICE AND A DISPLAY DEVICE

摘要

The display device of the present invention comprising a a display panel (110) which comprises a plurality of scanning lines (SLia,SLib)arranged in rows and a plurality of data lines (DLja ... DLjd) arranged in columns ; and a plurality of display pixels (EM) arranged in matrix form near the intersecting point of the plurality of scanning lines and the plurality of data lines; a scanning driver circuit (120) which selects simultaneously the display pixels of a plurality of rows connected to some of the plurality of scanning lines of the display panel; and a signal driver circuit (130) which comprises a current generation circuit (CG) which generates signal currents and supplies the display data that provides the display gradation for each of the display pixels and have a current value according to the value of the display data and a plurality of current holding circuits (CH) supplied with the signal currents which take in and hold the signal currents corresponding to the display pixels of the plurality of rows selected by the scanning driver circuit (120) and outputs simultaneously the gradation currents to each of the plurality of display pixels in the plurality of scanning lines based on the signal currents. The display panel comprising a plurality of scanning line groups (SLi) which constitute sets of the plurality of scanning lines through which simultaneous selection is performed by the scanning driver circuit; a plurality of scanning signal lines (SSLi) which are connected to each of the plurality of scanning line groups; and a plurality of data line groups (DLj) which constitute sets of the plurality of data lines corresponding to the line count of the display pixels of the plurality of rows connected to each of the scanning line groups within the plurality of data lines.
