An apparatus and method for gathering and reporting interference signal information between Relay Stations in a multi-hop relay Broadband Wireless Access communication system are provided. The backlight unit further includes an elastic optical guide member coupled to the light guide plate, the elastic optical guide member having a substantially same curvature as the curvature of the light guide plate. A prediction picture signal is generated in accordance with the reference picture number and predictive parameter of the selected combination. A die is attached to the die attach paddle. Then, a transformation electric field which is formed between the reference electrode and the data electrode makes the display panel transform into the normal display state quickly. The second terminals of the first and second transistors are connected by discrete first and second gang clips to respective substrate pins.
