6）视角：水平视角≥160°，垂直视角≥160°                                                         
7）箱体平整度：≤0.1mm ，箱体间缝隙≤0.1mm                                                                           8）显示屏亮度≥600                                                                                9）刷新频率≥3840Hz                                                                                    10）对比度≥ 10000:1                                                                                       11）色温可调范围：2000k~10000k                                                                     12）峰值功耗≤700W/㎡，平均功耗≤300W/㎡                                                                             13）亮度均匀性≥98%                                                                                      14）色度均匀性（校正后）+0.003Cx,CyG之内                                                                                                                                             15）发光点中心距偏差≤3%                                                                           16）低灰高亮：亮度 16bit 灰度，20%亮度 15bit 灰度                                                                                                                                                                                                                                                                              17）屏体模组采用4.5-5.0VDC的安全电压供电，定制3C电源，具备PFC电源                                                                                                                                                                                       18）支持屏体拼缝亮线、暗线校正
19）电源系统为N+1冗余备份，当其中一路交流电网跳闸后，另外一路电网继续供电，实现不间断供电，支持热备份，当其中一块电源失效后，另一块电源断续工作，从而失现不间断供电
