4×4、6×6、8×8矩阵排列的组合屏电视墙具有组合屏大画面显示、分屏幕小画面同时或轮流显示,四分画面显示和镜像效果、叠像效果、油画效果、冻结效果、万花筒效果、慢动作及其相互间的组合,计128种以上的显示功能。显示方式由电脑控制,可定时编程。试制中我们采用了信号的隔行/逐行变换,行内插(垂直滤波),水平滤波和宽范围锁相环等技术,使电视墙显示图像的清晰度和稳定性高于国外水平,成本仅是国际市场的1/3。
Combination of 4 × 4,6 × 6,8 × 8 matrix screen TV wall with a combination of large-screen display, sub-screen small screen at the same time or in turn display, quarter-screen display and mirror effects, overlay effects, painting effect, freeze Effect, kaleidoscope effect, slow motion and their combination with each other, counting more than 128 kinds of display functions. Display mode controlled by the computer, can be timed programming. In trial production, we adopted techniques such as signal interlaced / progressive conversion, line interpolation (vertical filtering), horizontal filtering and wide-range phase-locked loop to make the display and resolution of the video wall higher than that of foreign countries at a cost of only 1/3 of the international market.
