Abstract

The embodiment of the invention discloses a phase inverter, a display driven circuit and a display panel, wherein the phase inverter comprises a first control module, a first switch module, a second switch module, a second control module, and a first output module; the first switch module and the second switch module are connected and disconnected according to signals input by respective control terminals; in connection, level signals input by a first level signal input terminal are transmitted to the output terminal of the phase inverter; the control terminal of the second control module is electrically connected with the input terminal of the phase inverter, the input terminal thereof is electrically connected with a second level signal input terminal, and the output terminal thereof is electrically connected with the control terminal of the first switch module; by the first output module, level signals input by a third level signal input terminal are transmitted to the output terminal of the phase inverter when the first switch module is disconnected. By the technical solution provided in the embodiment, a threshold shift problem caused by connecting the switch modules in the phase inverter for a long time is solved and circuit stability is increased.

Description

technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular, to an inverter, a display driving circuit and a display panel. Background technique [0002] Existing display panels generally include several pixels, each pixel includes a pixel driving circuit, and the pixel driving circuit is generally provided with at least one switching transistor, one driving transistor and at least one capacitor. For a pixel driving circuit, generally at least one scanning signal, at least one light emitting signal and one data signal need to be provided. For example, for a certain pixel driving circuit, the provided scan signal controls the switching transistor in the pixel driving circuit to turn on, the provided data signal charges the capacitor, and compensates the threshold value of the driving transistor. After the threshold value of the driving transistor is compensated, The provided light-emitting signal can control so...
