The invention discloses a light-emitting control signal drive circuit and an active matrix-type display panel, and belongs to the technology of display panel control. The circuit provides a first time sequence signal and a drive signal, and comprises drive units at multiple levels. The first time sequence signal comprises two level states in a signal period, and alternately switches the two level states at a preset frequency. Each drive unit enables an input signal to be delayed for a preset time period and outputted according to the control of a control signal. The first drive unit takes the drive signal as the input signal, and the other drive units respectively take the output of the former drive unit as an input signal. The first drive unit takes the first time sequence signal as the control signal, and the other drive units respectively takes the delayed control signal of the former drive unit as the control signal. The beneficial effects of the technical scheme are that the circuit reduces the time sequence signals for controlling the active matrix-type display panel, and enables a complex time sequence control circuit structure to be simplified.
Description
technical field [0001] The invention relates to an active matrix display panel control technology, in particular to a lighting control signal drive circuit and an active matrix display panel. Background technique [0002] Active matrix (ActiveMatrix / OrganicLightEmittingDiode, AMOLED) display panel refers to a display panel in which organic semiconductor materials and luminescent materials are driven by control signals to emit light and realize display. , Self-illumination, fast response, high definition, low energy consumption, low temperature and excellent shock resistance, etc., are considered to be the most promising display technology. [0003] In the prior art, the control of the AMOLED display panel usually requires the input of multiple timing signals to complete, and the connection mode of the control circuit structure is also relatively complicated (such as figure 1 As shown), it is not conducive to the realization of the control mode of the AMOLED display panel. ...
