The 3-inch LCD monitor features approximately 920,000 dots (VGA res), a wide (160º) viewing angle, high brightness and low power consumption. Colors and color reproduction have been improved over the EOS-1D Mark III. Natural-looking images close to the sRGB color space are obtained. Also, even with the magnified view, the resolution is appropriate for checking focus precision. In sum, the new LCD delivers the finest performance Canon has ever offered.
With older LCD designs, light reflections on and in the LCD monitor hindered visibility. These reflections occurred because the protective cover surface and liquid crystal panel surface had air (with a different refractive index than those surfaces) between them. Previously, these surfaces had anti-glare coatings to reduce reflections.With the EOS-1D Mark IV, instead of just reducing reflections, the idea was to eliminate the cause altogether. The space between the protective cover and liquid crystal panel is filled with an optical elastic resin material that has a carefully matched refractive index. The filling creates a borderless structure. Light reflections inside the LCD monitor have thereby been drastically reduced.As a result, the blacks look crisp and the display has high contrast. Also, menus and displayed images can be viewed closer to the protective cover’s top surface.

Beim Sony Display wird darauf wohl verzichtet den Zwischenraum aufzufuellen und das Schutzglas direkt auf das LCD Panel aufgebracht, window-on ;).
