Abstract:
A process for forming a polycrystalline silicon layer includes the following steps. Firstly, at least one seed is formed on a substrate. Then, an amorphous silicon layer is formed on the substrate and overlies the seed. Then, the amorphous silicon layer is irradiated with a laser to melt the amorphous silicon layer. Afterward, the molten amorphous silicon layer is recrystallized to form a polycrystalline silicon layer.

Abstract:
A one-piece beverage carton has two handle panels, two side panels, two fascia panels, a primary bottom panel, a secondary bottom panel and two side bottom panels. The handle panels abut each other and have hand holes formed therethrough. The side panels are formed adjacent to the handle panels and each side panel has a structural strip and two folding strips being shorter than, formed on and folding along opposite edges of the structural strip. The fascia panels have a top edge and are connected to the handle panels by at two partitions formed on and folded against the fascia and handle panels. The bottom panels are formed on and folded against the fascia and side panels to form a bottom of the carton. The beverage carton therefore creates less material waste, is strong and easily folded for storage and transportation.
Abstract:
A pixel driving circuit for OLED display apparatus is provided. The pixel driving circuit is adapted to drive an OLED having a first terminal and a second terminal, while the first terminal couples to a first voltage source. The pixel driving circuit comprises a control circuit, a driving transistor and a diode. The control circuit generates a control signal to control an OLED current supplied to the OLED. The driving transistor has a first drain/source terminal, a second drain/source terminal and a gate terminal. The gate terminal receives the control signal to control a channel between the first and second drain/source terminal for adjusting the OLED current flowing through the channel. Further, the diode couples between the channel and a second voltage source.
