The present invention provides an OLED gate driving circuit structure, comprising an OLED panel, a gate charge/discharge driving circuit, a logic process unit and a source driving circuit; the gate charge/discharge driving circuit is located at one side of the OLED panel, and the gate charge/discharge driving circuit comprises a plurality of output ends, and each output end is electrically coupled to the logic process unit with one signal line; the logic process unit is located inside the OLED panel, and the logic process unit receives a scan signal transmitted by the gate charge/discharge driving circuit through the signal line, and converts the scan signal into a discharge scan signal and a charge scan signal to be provided to the OLED panel; the source driving circuit is coupled to the OLED panel, and provides a data signal to the OLED panel, and only one gate driving integrated circuit is utilized in the structure for achieving the charge and discharge procedures of the gate driving circuit to save the hardware cost and to simplify the panel layout circuit and to make the frame of the panel narrower.

OLED gate driving circuit structure

An OLED drive system raising a frame contrast and a drive method are disclosed. The OLED display panel is equally divided into a plurality of display divisions along a vertical direction. The brightness calculation module is employed to calculate average pixel brightnesses corresponding to the respective display divisions in the OLED display panel. On one hand, the power management module is employed to supply different reference voltages for the respective display divisions correspondingly according to the average pixel brightnesses of the respective display divisions in the OLED display panel, and respectively insert the reference voltages of the respective display divisions into reference voltage lines corresponding to the pixels of middle rows in the display divisions to make the reference voltages of the respective display divisions be different for raising the frame contrast.

The present invention provides a source driver and a source drive method of a liquid crystal panel of unequal row drive width. By providing the input signal decoding control unit electrically coupled to the plurality of data signal output channels and encoding the data signal output channel start address signal and the data signal output channel end address signal in the transport packages of the data signal to be transported to the input signal decoding control unit, the input signal decoding control unit controls the amount of activated data signal output channels to adjust the row drive width for each scan according to the received data signal output channel start address signal and the received data signal output channel end address signal. The row drive width of scan for each row can be dynamically adjusted to transport the data signal to the pixels required to display in each row. It is applicable for non rectangular display for reducing the output power of the liquid crystal panel and the source driver of the liquid crystal panel of unequal row drive width is derived from the present drive structure design. The structure is simple.
