Abstract: According to an aspect of the present disclosure, there is provided a substrate treating apparatus comprising: a vessel part having a substrate treatment region formed therein and including a supply port through which a treating fluid is supplied to the substrate treatment region and an exhaust port through which the treating fluid is exhausted from the substrate treatment region; a fluid supply unit configured to supply the treating fluid to the substrate treatment region; an exhaust unit configured to exhaust the treating fluid from the vessel part. The exhaust unit comprises: a main line connected to the exhaust port; an extension line branched from at least one of first and second nodes of the main line and including at least one of a first orifice or a first check valve to control an exhaust speed; and an auxiliary line branched from a third node of the main line, where an orifice and a check valve are not formed.

Abstract: An image display apparatus includes: an interface unit which receives an image signal; a main controller which performs a control operation for processing the image signal in a normal mode state; a sub-controller which performs a control operation for providing a low power service in a power saving mode state; and a switch unit which connects the interface unit to the main controller in the normal mode state and is switched in the power saving mode state to connect the interface unit to the sub-controller.
