Patent Searching and Data


Title:
A data processing method in a display and a display
Document Type and Number:
Japanese Patent JP6012768
Kind Code:
B2
Abstract:
An embodiment of the present invention is directed to reducing a memory capacity required for saving compensating data (data used for compensating variations and the like in characteristic of a drive transistor) compared to conventional examples, in a display device. An organic EL display device using an oxide TFT for a drive transistor is provided with: a low pass filter for extracting low frequency component data from pixel current data as data of a drive current of the drive transistor; a first computing portion for obtaining high frequency component data by obtaining a difference between the pixel current data and the low frequency component data; a down-sampling portion for extracting data from the low frequency component data at predetermined sampling intervals; and a high frequency signal compression processing portion for extracting only high amplitude data out of the high frequency component data.
