Pixel unit circuit and oled display apparatus |
摘要 |
<p>The present disclosure discloses a pixel unit circuit and an OLED display apparatus. The pixel unit circuit comprises a first sub-circuit module (11 and 12), a second sub-circuit module (21, 22, 23 and 24), a first capacitor (3) and OLED (4). An input of the first sub-circuit module is connected to a data line (Data); another input of the first sub-circuit module is connected to an output of the second sub-circuit module and a first terminal of the OLED; an output of the first sub-circuit module is connected to an input/output of the second sub-circuit module via the first capacitor; a voltage difference between positive power supply (ARVDD) and negative power supply (ARVSS) of a backboard is applied between an input of the second sub-circuit module and a second terminal of the OLED. The pixel unit circuit can compensate the aging of OLED devices, the non-uniformity of threshold voltage of TFT driving transistors, and a drop in the driving current IR Drop of the power supply of the backboard.</p> |
