Abstract: The disclosure provides a projection system and a gamma curve correction method. The projection system includes a projection target and a projection device. A test image is projected on the projection target. The projection device obtains a first gamma curve of the test image by receiving the test image projected on the projection target or sensing a light beam of the projected test image, and judges whether multiple difference values between the first gamma curve and a preset gamma curve is larger than a preset value. The first gamma curve is corrected to generate a second gamma curve when at least one of the difference values is larger than the preset value. The projection system and the gamma curve correction method of the disclosure provides an ideal gamma curve according to the output performance of the use situation.

Abstract: A display includes a main frame, a support base, and a locking mechanism. The support base including a first locking member is selectively connected to the main frame. The locking mechanism selectively connected to the first locking member of the support base includes a base, a plate, a pivot, and a second locking member. The base with a hole is movably disposed on the main frame. The plate is connected to the base, and is neighboring the hole. The pivot including a raised edge is disposed on the main frame, through the hole, and is near the plate. The second locking member is connected to the base for selectively engaging with the first locking member. When the raised edge abuts against the plate, the base is moved towards the first direction, and the second locking member is detached from the first locking member.
