Abstract: The present disclosure provides a touch panel comprising a touch electrode layer provided with a mesh-shaped groove on an entire surface thereof. The mesh-shaped groove comprises strip-shaped grooves arranged to cross each other. The mesh-shaped groove divides the touch electrode layer into a plurality of conductive units arranged in an array. The conductive units located in a same electrode pattern in the touch electrode layer are electrically connected together by providing a groove break in each of the strip-shaped grooves among them. The mesh-shaped groove relates to inside and outside of different electrode patterns in the entire touch electrode layer, thereby blurring boundary shape of each electrode pattern and decreasing difference in shape and vision between different electrode patterns. This makes the entire touch electrode layer have a uniform surface, thereby reducing probability of seeing electrode patterns in the touch panel and improving visual effect of the touch panel.

Because size of the pixel driving circuits is much larger than a width of traces, each width between adjacent pixels is increased. This avoids light leakage caused by pixel intervals being too small.

Abstract: An agent module of a host directs I/O requests accessing a first disk of a first storage array to access a second disk of a second storage array. The agent module obtains a disk identifier of a first disk in the first storage array and a disk identifier of a second disk in the second storage array to record a mapping relationship between them. The agent module further reports virtual path information for a virtual path between the agent module and a multipath module of the host to the multipath module. The agent module sends the disk identifier of the first disk via the virtual path after receiving a disk identifier query request for querying the identifier of the second disk. Thus, the agent module can send an I/O request for accessing the first disk to the second storage array to access the second disk.
