Spliced display screen

Abstract

The invention discloses a spliced display screen, and overcomes the problem that the splicing gap of a traditional spliced display screen is too large. The spliced display screen is formed by splicing 2N display assemblies, each display assembly comprises a screen, a splicing frame and a projection box, the protection box includes a rectangular installation frame which is convenient to install, the splicing frame comprises two vertical splicing plates and two horizontal splicing plates, the length of the vertical splicing plates is the same with that of a vertical support of the installation frame, the length of the horizontal splicing plates is the same with that of a horizontal support of the installation frame, one side of each splicing plate is vertically and fixedly connected with the installation frame via a right-angle connecting piece, the opposite side of the splicing plate is provided with multiple splicing holes, each side of each screen is provided with screen holes, the screen holes and splicing holes are penetrated by clamping pins, and the thus the screen is vertically and fixedly connected with the splicing frame. The spliced display screen is simple in structure and convenient to assemble, realizes seamless and infinite splicing, reduces the production cost and is suitable for large-scale production and application.

Description

technical field [0001] The invention relates to a large DLP spliced ​​display screen, in particular to a seamless stitched spliced ​​display screen. Background technique [0002] At present, DLP large-screen splicing display screens are all made of composite glass material, which is made of multiple layers. It is too complicated to process and assemble, and it takes time and effort to transport the glass. Because the glass is added to the front and back of the composite glass screen, it is blocked to a certain extent. The penetration of light will greatly reduce the image quality, and the seam is more than 1mm, and it will cause the glass to fall and hurt people. [0003] The original structure uses custom-made aluminum profiles as the main structure of the display screen. According to the size requirements, it is processed into two long sides and two short sides, and then four connecting hinges are used to fix the structure of the aluminum profiles to form a proportional cu...

[0002] At present, DLP large-screen splicing display screens are all made of composite glass material, which is made of multiple layers. It is too complicated to process and assemble, and it takes time and effort to transport the glass. Because the glass is added to the front and back of the composite glass screen, it is blocked to a certain extent.

[0003] The original structure uses custom-made aluminum profiles as the main structure of the display screen. According to the size requirements, it is processed into two long sides and two short sides, and then four connecting hinges are used to fix the structure of the aluminum profiles to form a proportional cuboid. The size requirements for aluminum profiles are high. When the size deviation is large, the glass cannot be matched with the aluminum alloy frame. When the screen is spliced, there will be serious mechanical splicing seams, which will have a great impact on the display effect.
