Splicing frame for video wall display units, and video wall

Abstract

The invention relates to the technical field of display, and discloses a splicing frame for video wall display units, and a video wall. According to the splicing frame and the video wall, area overlapping between adjacent display units and flip chip thin film plates and between adjacent display units and printed circuit boards is reduced, and the splicing structure of the video wall is optimized. The pair of opposite lateral sides of the splicing frame respectively comprise a first side plate, a first limiting bottom plate connected with the first side plate and located inside the first side plate, a clamping groove connected with the first side plate and bent towards the outer side of the first side plate, a second side plate, a second limiting bottom plate connected with the second side plate and located inside the second side plate, a clamping protrusion connected with the second side plate and bent towards the inner side of the second side plate, and two adjacent splicing frame bodies in the first splicing direction, wherein the flip chip thin film plates of the display units and the printed circuit boards can be bent into the portions between display unit bodies and the first side plates, and the clamping protrusion of each splicing frame body can be clamped into the clamping groove of the corresponding splicing frame.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a splicing frame of a video wall display unit and a video wall. Background technique [0002] With the continuous maturity of display technology, large-area display devices are widely used in military, public security, railway, aviation, finance, securities and other fields. The video wall is a computer-based display, playback and control system, including multiple display units that are spliced ​​together. Users can flexibly choose the display mode of the video wall, for example, select a certain group of screens, full screen or custom multi-screen show. [0003] At present, in order to meet the needs of the market, more and more manufacturers are committed to developing video walls with transparent display effects, so as to bring a new interactive experience to users. Such as figure 1 As shown, when developing a video wall with a transparent display effect, it is found that...

AI Technical Summary

Problems solved by technology

like figure 1 As shown, when developing a video wall with a transparent display effect, it is found that after the transparent display unit 200 is spliced ​​through the existing splicing frame 100 ′, the chip-on-film board 210 (Chip On Film, COF for short) and the printed circuit board 220 ( The Printed Circuit Board (PCB for short) is located behind the screen and is visible, which affects the transparent display effect of the video wall; if the chip-on-film board and the printed circuit board are blocked by the frame, the splicing line of the video wall will be more obvious and effective The area of ​​the display area will be greatly reduced
