  • Patent number: 10700151
    Abstract: An organic light-emitting diode display may have an array of pixels. The pixels may each have an organic light-emitting diode with a respective anode and may be formed from thin-film transistor circuitry formed on a substrate. A mesh-shaped path may be used to distribute a power supply voltage to the thin-film circuitry. The mesh-shaped path may have intersecting horizontally extending lines and vertically extending lines. The horizontally extending lines may be zigzag metal lines that do not overlap the anodes. The vertically extending lines may be straight vertical metal lines that overlap the anodes. The pixels may include pixels of different colors. Angularly dependent shifts in display color may be minimized by ensuring that the anodes of the differently colored pixels overlap the vertically extending lines by similar amounts.

  • Patent number: 10651155
    Abstract: Systems and methods are described for improved heat dissipation of the stacked semiconductor dies by including metallic thermal pads between the dies in the stack. In one embodiment, the thermal pads may be in direct contact with the semiconductor dies. Heat dissipation of the semiconductor die stack can be improved by a relatively high thermal conductivity of the thermal pads that directly contact the adjacent silicon dies in the stack without the intervening layers of the low thermal conductivity materials (e.g., passivation materials). In some embodiments, the manufacturing yield of the stack can be improved by having generally coplanar top surfaces of the thermal pads and under-bump metallization (UBM) structures.
