The present invention provides a curvature-adjustable backplane and a liquid crystal display device having the backplane. The present invention employs an interactive verification and sector erase algorithm to verify and repeatedly erase the sector until a portion of the groups of each page of the sector are erased or a first maximum number of erase pulses is achieved. Data may be transferred from a master latch to a slave latch through a transfer circuit in response to an edge of a clock input signal. The razor blade assembly may also have an array of closely spaced droplets of a liquid adapted to inhibit corrosion of the razor blade applied to the side of the razor blade visible to a user.
