Abstract

The invention discloses a parallel structure with multiple sets of embedded touch-control liquid crystal displays, which includes a display installation limiting mechanism and a bearing outer frame fixing mechanism, and both sides of the display installation limiting mechanism are movably connected to the bearing outer frame fixing mechanism. When installing multiple groups of displays in this parallel structure, they can be respectively put into the corresponding display installation limit card slots, and the first wire connection hole and the second wire connection hole can be used to connect wires to each other to form a parallel connection. The structure realizes the parallel connection of AC constant voltage sources, and because of the parallel shunt, when the inflowing current is too large, it can be shunted, and it is not easy to burn out. Even if a display branch is damaged and disconnected, the other display will still form a path with the main circuit and maintain normal operation. Compared with the general series connection method, the safety is also higher.

Description

technical field [0001] The invention relates to the technical field of display installation equipment, in particular to a parallel structure of multiple groups of displays embedded with touch-type liquid crystals. Background technique [0002] The current main technology development direction of touch display can be divided into two types: plug-in type and built-in type. The plug-in technology is to superimpose a layer of touch panel on the outside of the display panel without touch function, while the embedded technology is to directly insert the touch sensor into the pixel structure of the display panel. Since the in-cell touch display intersperses at least one touch-sensing period in each screen period, and whenever the in-cell touch display operates in the touch-sensing period, the grid of the in-cell touch display In the pole drive circuit, the level of the gate of the drive transistor in the shift register corresponding to the first gate line after the current touch s...
