Abstract
This invention discloses a large size screen fixing method, which comprises the following steps: 1, putting picture frame on the base plate; 2, putting screen on the frame; 3, pressing the screen pressure plate on the screen; 4, screwing the screen pressure plate bar. This invention realizes the non-sinking and deformation of screen by adopting the above technique. When putting down screen, the screen is put with pressure plate to press the screen and screen pressure bar sub-force prevents the Fresnel lens plate deformation by gravity when screwing the four edges of screen pressure bar.
Description
[technical field]
The present invention relates to a kind of installation method of large scale screen, LCD especially, DLP, the installation method of digital optical display rear-projector's screens such as LCoS.
[background technology]
LCD, DLP, digital optical display rear-projectors such as LCoS are because its size is big, cause screen excessive overweight, limit by screen material, screen is big more, whole just soft more, therefore when mounted, owing to the gravity of screen self causes the middle part to be sunk installing undesirable, influence imaging effect, on the other hand, because opening complete screen, each forms by Fresnel lens plate and two of lenticular lens sheets, be coherent between two runner plates by the thin gummed paper on edge, surrounding, this mutual illusive fixed form, be doomed to have the phenomenon of single element lens plate independent deformation, therefore when with screw locking screen press strip, can sink because of gravity deformation in the lenticular lens sheet middle part, and the pressure of screen press strip can be decomposed into the component F1 of normal to screen and component F2 two parts of parallel screen sensing screen inboard, the situation of Fresnel lens plate because of being caused the middle part to be heaved by the component F2 effect of screen press strip pressure all around, as shown in Figure 1, like this, will form the space at the center section of Fresnel lens plate and lenticular lens sheet, cause the screen installed very soft, image blur etc. bad phenomenon.
[summary of the invention]
Purpose of the present invention is exactly in order to solve above large scale screen very straight solid problem to be installed, and a kind of installation method of large scale screen is provided.
For achieving the above object, the present invention proposes a kind of installation method of large scale screen, comprises the steps: 1) the face frame is placed on the substrate, the boss plane in the middle of the substrate is enclosed within the hollow bulb of face frame; 2) screen is positioned in the face frame; 3) the screen pressing plate is pressed on the screen; 4) with the screen press strip around the screw locking screen pressing plate.The boss plane sizes of substrate is consistent with the viewing area of face frame in the step 1); The height on boss plane just is the distance of face frame appearance plane to the plane of placing screen.
Because adopted above scheme, when screen was placed on the face frame, the edge of screen dropped on the face frame, the screen center section by the platform holder of the projection of substrate, thereby realizes that screen can not descend notch distortion when mounted.After placing screen, just on screen, put pressing plate, make the gravity pressure of pressing plate screen, when locking the screen press strip on four limits with screw, the component F2 of screen press strip fails Fresnel lens plate is pushed away distortion because of the action of gravity of pressing plate.Thereby hollow when having prevented from screen is installed and soft phenomenon make the practicality of large scale screen strengthen greatly.
[description of drawings]
Fig. 1 is the phenomenon synoptic diagram that general installation screen is occurred.
Fig. 2 is the synoptic diagram that the present invention installs screen.
[embodiment]
Also the present invention is described in further detail in conjunction with the accompanying drawings below by specific embodiment.
As shown in Figure 2, placed side frame 1 on substrate 6, make the boss plane of substrate 6 be enclosed in the face frame in aerial, then screen is put into face frame 1, screen is made up of Fresnel lens plate 3 and lenticular lens sheet 4, after screen places, depresses screen pressing plate 5 on screen, with screw locking screen press strip 2, promptly realize installing the screen operation then.In order to protect screen and the unlikely wearing and tearing of face frame, wick flannelette or other soft protective seams are all coverd with in substrate 6 and pressing plate 5 surfaces.
Substrate 6 smooth and platform of intermediate projections, screen pressing plate 5 is smooth, substrate 6 is used for placing the face frame 1 that screen is installed, the platform size of substrate 6 intermediate projections is complementary with the viewing area of face frame 1, the podium level of projection just is the distance of face frame 1 appearance plane to the plane of placing screen, when frame 1 was placed on the substrate 6 face to face, the platform of the projection of substrate 6 was enclosed in the viewing area of face frame 1, and the fixed mask face of platform and face frame 1 is same plane.Make that the edge of screen drops on the face frame when screen being placed on the face frame 1, the screen center section by the platform holder of the projection of substrate 6, thereby realizes that screen can not descend notch distortion when mounted.After placing screen, just on screen, put pressing plate 5, make the gravity pressure of pressing plate 5 screen, when locking the screen press strip 2 on four limits with screw, the component F2 of screen press strip 2 fails Fresnel lens plate is pushed away distortion because of the action of gravity of pressing plate.Thereby hollow when having prevented from screen is installed and soft phenomenon.
