Active matrix display apparatus

A display apparatus which has an active matrix type of display panel comprising a plurality of pixel units each having a light-emitting element and a drive transistor whose drive electrode is supplied with drive voltage driving said light-emitting element, a scan drive unit for sequentially scanning scan lines of said display panel, and a data drive unit for supplying a data signal based on a video signal to a control electrode of each of said drive transistors in association with scanning by said scan drive unit, said display apparatus comprising:

• a capacitor provided in each of said plurality of pixel units to hold said data signal, a first terminal of said capacitor being connected to said control electrode of said drive transistor;
• a capacitor voltage generating unit which generates a capacitor voltage to be applied to a second terminal of each of said capacitors;
• an average luminance calculating unit which calculates average luminance of a display screen based on said video signal;
• and
• a drive voltage adjuster which adjusts the drive voltage driving said light-emitting element of said drive transistors according to said average luminance.
