Abstract: The present disclosure provides a stage-number reduced gate driver on array (GOA) circuit and a display device. The circuit includes one or more stages of GOA sub-circuits. Each stage of GOA sub-circuits includes a gate signal input end, an original output end, one or more sub-output ends, and one or more branching devices respectively corresponding to the one or more sub-output ends. The gate signal input end and the original output end are respectively connected to a branching node. One end of the one or more branching devices is respectively connected to the branching node. Another end of the one or more branching devices is connected to the corresponding one or more sub-output ends. The present disclosure can solve the problem of excessive length of the GOA circuit in high-resolution model which is not conducive to a narrow bezel design.

Abstract: The present disclosure discloses a pixel circuit and a liquid crystal display panel. The pixel circuit includes a main TFT and a sub-TFT connected in parallel. A resistance of the main TFT is less than a resistance of the sub-TFT. a voltage applied to the sub-TFT is less than a voltage applied to the main TFT by utilizing a voltage dividing function operated by the main TFT and the sub-TFT. The liquid crystal display panel includes the above-mentioned pixel circuit. The present disclosure can achieve different brightness of different domains by utilizing only two TFTs. Therefore, color shifting and transmittance of the panel is improved.
