English to French Tech/Engineering Photography/Imaging (& Graphic Arts) display device

The demultiplexer includes a plurality of first TFTs connecting a plurality of first lines of the plurality of lines and corresponding ones of the plurality of data lines, and a plurality of second TFTs connecting a plurality of second lines of the plurality of lines and corresponding ones of the plurality of data lines, wherein, when the defect detecting device drives the first to third DC lines to a voltage corresponding to an intermediate grayscale among a grayscale range, detects a short defect in the plurality of lines causing the pixel array connected to the shorted line to emit light with a high luminance different from the intermediate grayscale or not to emit light at all, the plurality of the first switches and the plurality of the second switches are in an on state, simultaneously, and only one of the plurality of first TFTs or the plurality of second TFTs are in an on state.

the defect detecting device is configured to drive the first to third DC lines (DC_R, DC_G, DC_B) to a gray-emitting voltage where the pixels (PX_R, PX_G, PX_B) do emit an intermediate grayscale,
