An improved plain old telephone service line card that may be directly connected to a customer line that is also connected to a digital subscriber line access module. During this process, the mean value of the statistical lag Ts is measured over a predetermined time duration takes place). Using a template having a predetermined size on the reference image, a motion vector is detected from the search target image. The micro-optic array is configured to perform a rotational transformation of the collimated emitter beams. The third thin film transistor includes a gate electrode, a source electrode overlapping the gate electrode and connected to the second sub-pixel electrode, and a drain electrode connected to the assistance capacitor, and a parasitic capacitance between the gate electrode and the drain electrode is equal to or less than a parasitic capacitance between the gate electrode and the source electrode.
