Abstract

The invention provides a data drive circuit, an electric compensation method, an array substrate and a display device. The method comprises the steps: acquiring a threshold value voltage signal of pixel of a row and a column by virtue of a first signal wire connected to the row of pixels when a first scanning signal of the pixels is received; converting the threshold value voltage signal to obtain a compensation voltage signal according to an external control signal corresponding to the pixels of the row and the column; receiving a data voltage signal of the pixels of the row and the column from a time sequence control circuit; adding the compensation voltage signal together with the data voltage signal to obtain an output voltage signal; and outputting the output voltage signal to the pixels of the row and the column by virtue of a second signal wire connected to the pixels while a second scanning signal of the pixels is received. By adopting the method, the problems in the prior art that the effect for compensating the threshold value voltage of an internal circuit of the pixel is limit, and the design complexity of a TCON board is caused by an external circuit can be solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a data drive circuit, an electrical compensation method, an array substrate and a display device. Background technique [0002] In today's market, consumers not only have strict demands on the appearance and quality of products, but also pay more attention to the price and practicality of products; in the field of display, especially Organic Light-Emitting Diode (Organic Light-Emitting Diode) , OLED) display field, OLED display device is widely accepted because of its wide color gamut, wide viewing angle, thin, lightweight, low energy consumption, high contrast, and excellent bendable functions, and gradually becomes the development direction of future display technology . [0003] However, in driving the OLED, the threshold voltage Vth of the driving TFT (Thin Film Transistor, thin film transistor) in each pixel is different, which will lead to uneven brightness of the display...
