Pixel compensation device and method, pixel driving device, timing control module and display apparatus

A pixel compensation device, comprising:

• a luminance conversion unit configured to receive color data for a sub-pixel unit and convert the color data into corresponding luminance signal data;
• an emitting voltage calculation unit configured to calculate preset emitting voltage data for the sub-pixel unit based on the luminance signal data;
• an emitting voltage offset calculation unit configured to receive the preset emitting voltage data, compare the preset emitting voltage data with a reference value of an anode voltage and/or a reference value of a cathode voltage for the sub-pixel unit to generate an emitting voltage offset;
• and
• a data conversion unit configured to read pre-stored emitting voltage offset compensation data for a driving transistor in the sub-pixel unit with respect to a gate-source voltage of the driving transistor and obtain corresponding first luminance compensation data based on the emitting voltage offset and the emitting voltage offset compensation data, and further configured to generate source luminance data based on the luminance signal data and the first luminance compensation data and output the source luminance data to a source driving module.
