Patent ID: 8681082

Claim:
An electronic unit provided with a display device, the display device comprising: a plurality of pixels each including a light-emitting element; scan lines and signal lines, each line being connected to corresponding pixels of the plurality of pixels; a scan line drive circuit applying a selection pulse to each of the scan lines in succession, the selection pulse allowing a group of pixels to be selected from the plurality of pixels; and a signal line drive circuit writing video signals to respective pixels selected by the scan line drive circuit through switching a gray-scale interpolation voltage, a basic voltage, and a video signal voltage, one after another in this order, to apply each voltage selected by switching to each of the signal lines, wherein the signal line drive circuit performs gray-scale interpolation on a light emission luminance level for each of the light emitting elements through setting the video signal voltage to a fundamental gray-scale voltage corresponding to one of a plurality of gray-scale values which are originally provided by the video signals, and through varying the gray-scale interpolation voltage over a plurality of voltage values, the signal line drive circuit adjusts a period of the gray-scale interpolation voltage, in such a manner that the period of the gray-scale interpolation voltage gets shorter as a distance along the signal line from the signal line drive circuit to each of the pixels increases, and the scan line drive circuit starts an application of the selection pulse during a period of the gray-scale interpolation voltage, and completes the application of the selection pulse during a period of the basic voltage.
