Note 1) The source output at the “non-lit display” level is determined according to the PTS bit setting.
Note 2) Gate lines are scanned in the manner determined by the PTS bit setting during the non-lit display.
OSDE0: Display enable bit for OSD image 1.
OSDE1: Display enable bit for OSD image 2.
OSDE2: Display enable bit for OSD image 3.
OSDE0/OSDE1/OSDE2 = 0, the HD66781 does not display OSD images. Only base images are displayed.
OSDE0/OSDE1/OSDE2 = 1, the HD66781 displays OSD images according to the α channel bits in the
pixel data of the OSD image.
When OSDE =1, while a base image is not displayed (BASEE =0), an OSD is displayed with 100%
transmission rate.
