Abstract: Disclosed are a photovoltaic frame and a photovoltaic module. The photovoltaic frame includes a top support portion, a bottom support portion, a transverse edge portion, a first side edge portion and a second side edge portion. The top support portion, the transverse edge portion and the second side edge portion enclose a holding slot, and the top support portion has a bearing surface facing the holding slot. The photovoltaic frame alternatively includes a third side edge portion configured to connect the top support portion and the bottom support portion. The photovoltaic frame further includes a weather-resistant protective layer, covering a part of outer surfaces, that are in contact with external environment, among the top support portion, the bottom support portion, the first side edge portion, the second side edge portion, the transverse edge portion, and the third side edge portion if included.

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.

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.
