The 2nd one looks interesting as the following is the description
The panel is a new Panasonic LCD panel. Key Specifications/Special Features: Resolution (H x V): 800 x 480 Display: 7 inches (16:9), TFT LCD Brightness: 150cd/m2 Input: composite video (RCA) (F) x 2, S-video (mini DIN 4-pin) (F) x 1, NTSC
That looks to me as though its the same panel as the Xenarc and the TM-7002 that DigitalWW sell. However they quote the resolution as 800*480 (i.e appears to be the pixel res not element res quoted) and the cd/m2 as only 150 so not eniterly sure.
