Method and the driver which control passive matrix OLED display

摘要

OLED which was assembled with matrix form the passive matrix OLED display which it possesses (2) method and the unit which (1) are controlled are stated, the line which is controlled is connected OLED (2) by current source (3), line is connected, line addressing time (t) continuing mutually during duration. The lightness of the pixel which is arranged in turning sideways in the line and address the line which is appointed (L), line address time (t) turn on time inside (t) and the influence with the amplitude line electric current (I) is received. The electric charge quantity where in order to achieve energy efficient control, post luminescence time (t) it changes the line to a state where it does not have electric potential in, is supplied in is converted the electric charge quantity which (Q) the occasion where it specifies, before the addressing the electric charge quantity where OLED (2) is stored in capacitance (Q) by considering, the turn on time line electric current (I) (t), the electric charge quantity which is converted to light in (Q) and post luminescence time (t) OLED (2) capacitance (C) by OLED (2) in is converted to light (Q) Being controlled, the lightness of pixel (L) it is proposed that it controls. Selective figure It is not
