DISPLAY DEVICE, AND DATA PROCESSING METHOD IN DISPLAY DEVICE

摘要

An objective of the present invention in a display device is to allow reducing memory capacity necessary to save correction data (data used to correct drive transistor characteristic deviation, etc.) lower than existing technology. Provided is an organic electroluminescence (EL) display device when oxide TFTs are used in a drive transistor, wherein are disposed: a low-pass filter (421) which extracts low-frequency component data (IL) from pixel current data (I) which is drive current data of a drive transistor; a first computation part (422) for obtaining high-frequency component data (IH) by deriving the difference between the pixel current data (I) and the low-frequency component data (IL); a downsampling part (426) which extracts data from the low-frequency component data (IL) at a prescribed sampling interval; and a high-frequency signal compression processing part (427) which extracts only high-amplitude data of the high-frequency component data (IH).
