This product is the industry's first rental screen with dual power supply and dual-chip design. The dual power supply and dual-chip design solve the problem of the screen’s stagnation and discontinuity. The power supply and the chip are both up- and down-compatible, and can be safely replaced without interrupting the working condition display. This product is designed around a splicing right angle and square column shape. The left and right fast-arc lock can meet the needs of multiple angles, one of the features that make this a highly compatible product for the rental market.
