A heat dissipater has a heat conductive device. For each request in a queue, an associated processing time is determined using a system load andor the quality values. Thereafter, a black matrix is formed over the substrate, wherein black matrix defines the display area into a plurality of sub-pixel areas, and covers the non-display area, which forms an edge of the display area. The conductive layer has an isolated notch part located proximate the at least one bonding area.
