Abstract: The touch display panel drive circuit provided by the present invention comprises a data line drive unit, a plurality of gate lines and a plurality of data lines, and a junction of two adjacent gate lines and two adjacent data lines forms a pixel region, and a pixel switch is located inside the pixel region; the touch display panel drive circuit further comprises a data line switch between the data line and the data line drive unit; as the data line drive unit does not output the data signal, an output of the data line switch is a high-impedance state, and the data line drive unit is disconnected with the pixel switch. The present invention can prevent the error reading phenomenon generated by the transistor leakage, and can enhance the display brightness and the stability of the display image, and promote the display effect of the touch display panel.

Abstract: A display panel and a display terminal are disclosed. The display panel includes a display, a main board, and a FPC board connecting the display and the main board together. The FPC board has a portion of its surface attached with an EMI shielding layer. At least an edge of the EMI shielding layer is an edge with curves. The FPC board simplifies the assembly of the display panel, reduces production cost and maintenance inconvenience, and contributes to the display panel's downsizing. The EMI shielding layer prevents noises of different frequency ranges from affecting the display signals. The at least one edge with curves of the EMI shielding layer lessens stress between and therefore protects the EMI shielding layer and the FPC board from damages.

Abstract: A driving device for liquid crystal panel comprising: a scanning driver for applying a scanning voltage to pixels arranged as a matrix row by row; and a data driver for receiving an image data and a polarity inversion signal, obtaining original data voltages according to the image data, determining if amplifying the original data voltages along a scanning direction according to the polarity inversion signal, and providing the original data voltages or data voltage after being amplified to pixels. A driving method is also disclosed. When polarity inversion signal is inverted to a positive polarity from a negative polarity, the data voltages applied on the data line are gradually increased along a scanning direction. Accordingly, when the polarity inversion signal is inverted to a negative polarity from a positive polarity, the pixel which leaks current seriously is charged with a larger amount of charges, uneven display brightness is obviously decreased.
