OLED display panel
An OLED display panel is provided, including: sub-pixels arranged in an array; scanning signal lines, light-emitting signal lines, and first driving voltage lines extending horizontally; and data signal lines, at least one second driving voltage line, and at least one third driving voltage line extending vertically. Each scanning signal line, each light-emitting signal line, and each first driving voltage line are each connected to one row of the sub-pixels. Each data signal line is connected to one column of the sub-pixels. Each first driving voltage line arranged corresponding to each row of the sub-pixels is connected to the second driving voltage line through a first thin film transistor (TFT), and each first driving voltage line arranged corresponding to each row of the sub-pixels is connected to the third driving voltage line through a second TFT. Therefore, brightness deviation or color deviation is avoided when the sub-pixels emit light.
