Problems solved by technology

Each circuit part contains its own thin film transistor and capacitor. Therefore, the overall GOA unit circuit and cascaded GOA circuit include more thin film transistors and capacitors, and the GOA circuit is usually designed to be arranged on the edge of the pixel circuit. Therefore, it is not conducive to the narrow border design of the display
At the same time, the two circuit parts are independent of each other, and the problem of output misalignment is easy to occur.

Abstract

The invention discloses a GOA unit circuit comprising first to tenth film transistors, first to third capacitors, a SCAN signal input end, an EM signal input end, a SCAN signal output end, an EM signal output end, first to third clock signal ends, a high level end, a low level end, and A to C circuit nodes. The invention also discloses a GOA circuit; the number of film transistors and capacitors needed by the GOA unit circuit can be reduced, and the output signal is stable with no offset.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a Gated Driver On Array (GatedriverOnArray, array substrate row driver) unit circuit and a GOA circuit. Background technique [0002] In the field of display technology, it is a well-known technology to drive pixel circuits to work by GOA circuits. Wherein, the GOA circuit is formed by cascading multiple GOA unit circuits, and each GOA unit circuit drives at least one row of pixels. [0003] The GOA unit circuit can provide two types of signals: [0004] (1) Scan (SCAN) signal. The scanning signal is mainly used to turn on the thin film transistors of the row of pixels for a certain period of time, so as to scan the row of pixels into the data signal and store it in the capacitance of the row of pixel circuits. The scan signal or its shift signal can also be used to initialize the potential of the capacitor, or initialize the anode of the OLED. [0005] (2) Emit (EMI...
