Title:
ARRAY SUBSTRATE AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO2017008491
Kind Code:
A1
Abstract:
An array substrate and display device, the array substrate comprising: a plurality of scanning signal lines; a plurality of data lines (Ld); a plurality of pixel circuits (P1, P2, …, Pn), the plurality of pixel circuits (P1, P2, …, Pn) being provided at a crossing location of the plurality of scanning signal lines and the plurality of data lines (Ld); a current source circuit (S1), connected to first ends of the plurality of data lines (Ld), and configured so as to output, to the corresponding pixel circuits (P1, P2, …, Pn), a current corresponding to the pixel circuits (P1, P2, …, Pn), via the plurality of data lines (Ld); and a constant current circuit (S2), connected to second ends of the plurality of data lines (Ld), and configured to provide to the data lines (Ld), and from the first ends to the second ends, a current having a present value. Further provided is a display device comprising the above array substrate. The array substrate solves the problem of parasitic capacitance on a data line resulting in a small data current applied in the process of writing a small grayscale value having a large effect.
