Abstract
The present disclosure provides an OLED display device. The detection chip of the OLED display device includes a first and a second internal wirings spaced apart from each other, a plurality of first connection points and a third connection point between two ends of the first internal wiring are provided on the first internal wiring, a plurality of second connection points and a fourth connection point between two ends of the second internal wiring are provided on the second internal wiring. A reference voltage inputs toward the first and the second internal wirings via the third and the fourth connection points, further via the first and the second connection points to the plurality of sensing lines, finally inputs to the OLED panel. This can effectively reduce voltage variation of the reference voltage inputted to the sensing line through the detection chip, and make the detection chip has a smaller size.
