Abstract: The invention provides a driving method and driver circuit for in-cell touch display panel. The method comprises: Step 10: providing a GOA circuit, comprising a plurality of cascade GOA units; Step 20: controlling the n-th stage GOA unit to charge the n-th horizontal scan line of the touch display panel following a preset timing sequence; Step 30: dividing GOA units into first and second types of GOA units, with each first type GOA unit corresponding to a first horizontal scan line at which a next scanning starting after completing a TP scanning, and the remaining GOA units as second type GOA unit; Step 40: the size of first type GOA unit being greater than the circuit of second type GOA unit to provide a greater thrust to corresponding scan line than second type GOA unit. As such, the uneven display phenomenon of in-cell touch display panel is improved.

Abstract: The present invention relates to anti-counterfeiting field, and more particularly, to an anti-counterfeiting method, device and system based on textures of an object to be tested. The method includes: providing a light source based on a pre-determined anti-counterfeiting test model, projecting light emitted by the light source on a pre-determined test area, obtaining a pre-determined number of pictures of the pre-determined test area by means of a pre-determined optical sensor, acquiring texture characteristics of the pre-determined test area from the pictures, computing similarity between the texture characteristics and pre-stored texture characteristics and outputting a test result based on the similarity. The present invention implements anti-counterfeiting function by using the texture characteristics of the object itself and improves the anti-counterfeiting level greatly without increasing complexity of the production of the object.

Abstract: A connecting apparatus for connecting a first electronic device and a second electronic device together comprises a first port, a second port electronically connected to the first port, and a printed circuit board (PCB). The PCB comprises a first grounded region, a second grounded region, and a first electronic element. The first electronic element is electronically connected between the first grounded region and the second grounded region. When the first electronic device is electronically connected to the second electronic device together via the connecting apparatus, the first port is electronically connected to the first electronic device, and the second port is electronically connected to the second electronic device. The first grounded region, the first electronic element, and the second grounded region form a first return current path for allowing high frequency signals to pass through. A printed circuit board thereof is also provided.
