Problems solved by technology

As the size of the thin film transistor on the display device becomes larger and larger, the leakage current generated when the thin film transistor is not turned on becomes larger and larger, which may even cause the light emitting unit to emit light in the dark state, affecting the presentation of the display effect

Abstract

A light emitting circuit includes a light emitting unit, a driving transistor, and a bypass circuit. The driving transistor is used for driving the light-emitting unit. The bypass circuit transfers a current flowing from the driving transistor to the light emitting unit.

Description

technical field [0001] The present disclosure relates to a light-emitting circuit, and more particularly, to a light-emitting circuit with a bypass circuit, which can reduce the possibility of light-emitting units emitting light in a dark state. Background technique [0002] At present, light-emitting unit driving circuits used in display technology mainly include thin-film transistor elements. With the vigorous development of electronic products, the requirements for display quality on electronic products are getting higher and higher. As the size of the thin film transistor on the display device becomes larger and larger, the leakage current generated when the thin film transistor is not turned on becomes larger and larger, which may even cause the light emitting unit to emit light in the dark state, which affects the presentation of the display effect. [0003] Therefore, it is necessary to optimize the leakage current in the light-emitting circuit. SUMMARY OF THE INVE...
