  • Patent number: 12205523
    Abstract: A display module, a driving method, and a display device are provided. The display module includes a display panel. The display panel includes a plurality of data lines, a plurality of scan lines, and a plurality of sub-pixels. The sub-pixels are respectively located in a plurality of sub-pixel areas defined by the scan lines and the data lines. The display panel further includes a neutralization circuit. The neutralization circuit includes at least one control terminal and at least two coupling terminals. The at least one control terminal is configured to control connection/disconnection between the at least two coupling terminals. The at least two coupling terminals are respectively electrically connected to at least two of the data lines.

  • Publication number: 20230101184
    Abstract: An embodiment of the present invention provides a column inversion driving circuit. The column inversion driving circuit could reduce the voltage level of the logic low of the nth impulse signal, which is used to control the nth TFT matrix, through the cooperation of the voltage level of the nth impulse signal and the nth positive data signal. Furthermore, the voltage level of the logic high of the (n+1)th impulse signal, which is used to control the (n+1)th TFT matrix, is also reduced through the cooperation of the voltage level of the (n+1)th impulse signal and the (n+1)th negative data signal. This reduces the power consumption of the column inversion driving circuit.

  • Publication number: 20220301483
    Abstract: A GOA circuit and a display panel are provided. Each stage of GOA units is equivalent to multiple cascaded GOA units in the conventional GOA circuit and could orderly output multiple scan signals according to their timing such that each stage of GOA units could control multiple rows of the pixel units of the display panel to display an image. In this way, the number of the TFTs in the GOA circuit could be reduced, the layout and space of the GOA circuit could also be reduced such that the size of the side frame could be reduced and the narrow side frame demands could be met.
