Abstract

Embodiments of the present invention provide an emission controller, a control method thereof, and a display device, which relate to the field of display technology, and prevent the luminance of sub-pixels from deviating from a standard value, thereby improving display quality. The emission controller includes a plurality of emission control circuits, and the emission control circuit includes: a first processing module, which receives the first voltage signal, responds to the start signal and the first control signal, provides the first signal to the first node, and provides the second signal to the The second node; the second processing module, in response to the second control signal and the second signal, providing a third signal to the third node; the third processing module, receiving the second voltage signal, providing a fourth signal to the first node and the first node Three nodes; the fourth processing module, in response to the third control signal, pulls down the signal of the first node; the gating module receives the first voltage signal and the second voltage signal, responds to the third signal and the fourth signal, and provides The emission control signal is sent to the emission control signal terminal.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to an emission controller, a control method thereof, and a display device. 【Background technique】 [0002] The display device includes a plurality of sub-pixels arranged on the display panel and an emission controller for driving the sub-pixels to emit light. The emission controller includes multiple cascaded emission control circuits, the output end of each emission control circuit is connected to a row of sub-pixels, and the plurality of emission control circuits sequentially output emission control signals to make the sub-pixels receiving the emission control signals emit light. However, in the process of controlling the light emission of the sub-pixels by using the emission controller and the emission control circuit in the prior art, it will cause some adverse effects on the display screen and affect the display performance. 【Content of invention】 [0003] In view...
