The invention discloses a mounting adjusting assembly for a projection screen and the projection screen and relates to the technical field of displaying. The projection screen can be mounted very conveniently, and the position of the projection screen in the vertical direction can be adjusted. The mounting adjusting assembly for the projection screen is used for mounting the projection screen on amounting face and comprises an upper support and a lower support; the upper support comprises a fixed frame and an adjusting frame, the fixed frame is used for being fixed to the mounting face, and ahanging-connection part is arranged on the adjusting frame; the hanging-connection part is used for being connected with the upper end of the projection screen in a hanging mode to prevent the projection screen from moving downwards; the fixed frame and the adjusting frame are connected through an adjusting structure which can adjust the relative positions of the fixed frame and the adjusting frames in the vertical direction; and the lower support is used for being detachably connected with the lower end of the projection screen, and the lower support can limit the degree of freedom of the projection screen in the thickness direction. The mounting adjusting assembly is used for mounting the projection screen.
Description
technical field [0001] The invention relates to the field of display technology, in particular to an installation adjustment component of a projection screen and the projection screen. Background technique [0002] The projection screen is the peripheral equipment of the projector, which is used to receive the projection light of the projector. If it is properly matched with the projector, high-quality projection effect can be obtained. For example, laser TV, laser TV is composed of a laser light source projector and a projection screen using reflective ultra-short-focus projection technology, which can also display a good picture in a high-brightness environment. Compared with LCD TVs, laser TVs have more vivid colors and higher brightness. Moreover, it also has inherent advantages in the manufacture of super large screens. Compared with LCD TVs of the same size, the laser light source has a longer service life and lower power consumption, which meets the needs of society...
