Description

Display main body and splicing intelligent interactive panel

technical field

The invention relates to the technical field of display devices, in particular to a display body and a spliced intelligent interactive panel.

Background technique

In the field of high-end display engineering, large-screen image display has been widely used. The super-large screen and clear and realistic display effect it brings have greatly improved the quality of work in monitoring, security, conferences, simulation and other fields. Due to the size limitation of a single screen itself, in order to realize super-large screen display, multiple screens need to be spliced together to form a large spliced screen.

At present, most single screens hang the optical film around the backboard, and use a frame assembly composed of a press frame and an outer frame. The press frame is connected to the outer frame, and the press frame is used to press the optical film on the back plate. Therefore, the press frame part will be located in the display area of the glass cover, which will affect the display effect, and the frame assembly combined with the press frame and the outer frame will also increase the structural complexity, which is not easy to disassemble. The outer frame and the pressure frame will increase the width of the non-display area and affect the display effect.

In addition, the screen body often uses a direct-type backlight module as its backlight structure, while the conventional direct-type backlight module generally needs to use multiple support columns to support the diffuser plate in order to achieve a good backlight effect and structural stability. Among them, the common support columns are made of PC and PMMA, which are generally transparent or white, and have different shapes, but no matter what kind of material the support columns have, there is a disadvantage that the support columns are prone to shadows, especially when the direct-type backlight module is used. The smaller the size, the more obvious the shadow of the support column will be. At this time, more optical films are needed for shading, which will increase the cost of the backlight module. In addition, due to the long distance between the diffusion plate and the back plate of the conventional direct-type display, the overall thickness of the screen body is relatively thick.
