Input video and uniformity improvement signals should be symmetrical to VVC.
The input conditions for the uniformity improvement signal Vpsig differ for 4:3 display and 16:9 display.
1) During 4:3 display, input the voltage amplitude symmetrical to VVC as shown in Fig. 1.
2) During 16:9 display, input the same signal amplitude as in 1) above during the effective display portion,
and input the black signal level VpsigBK during the top/bottom black input portion as shown in Fig. 2.
