Abstract: A light source module including a light guide plate, at least one light emitting device, a light-controlling pattern element, and an absorbing pattern element is provided. The light guide plate has a light emitting surface, a first surface opposite the light emitting surface, and at least one opening. The opening passes through the first surface and extends from the first surface toward the light emitting surface. The at least one light emitting device is disposed in the opening and arranged along an arranging direction. The light-controlling pattern element is disposed on the light emitting surface and covers the opening and the light emitting device. The opening faces towards the absorbing pattern element. The absorbing pattern element is disposed besides one of the at least one light emitting device and extends toward a side wall of the opening. Moreover, another two light source modules are also provided.

Abstract: The description relates to an adjustable nozzle capable of pivoting about an axis of the nozzle and translating along the axis of the nozzle. A high density plasma chemical vapor deposition (HDP CVD) chamber houses a plurality of adjustable nozzles. A feedback control system includes a control unit coupled to the adjustable nozzle and the HDP CVD chamber to form a more uniform thickness profile of films deposited on a wafer in the HDP CVD chamber.

Abstract: An optically self-compensated birefringence liquid crystal display (OCB-LCD) panel including a first substrate, a first splay aligned layer, a second substrate and an OCB liquid crystal layer is provided. A first alignment layer is disposed on a surface of the first substrate. The first splay aligned layer is disposed on a surface of the first alignment layer, and the material of the first splay aligned layer includes a polymer polymerized by a first reactive mesogen (RM) monomer. The second substrate is disposed opposite to the first substrate, and a second alignment layer is disposed on a surface of the second substrate. The OCB liquid crystal layer is interposed between the first substrate and the second substrate.
