What are the main differences in the display quality between the Galaxy Z Fold 4 and the Galaxy Z Fold 5

Display Specifications
Both devices feature a 7.6-inch inner display and a 6.2-inch outer display, with both using Dynamic AMOLED technology and supporting a 120Hz refresh rate. The resolution for the inner display is 2176 x 1812, while the outer display has a resolution of 2316 x 904. These specifications are consistent across both models, providing vibrant colors and smooth scrolling experiences.

Brightness Improvements
A significant upgrade in the Z Fold 5 is its peak brightness capability. The Z Fold 4 can achieve a peak brightness of 1200 nits, whereas the Z Fold 5 can reach up to 1750 nits. This increase allows for better visibility in bright outdoor conditions and enhances HDR content playback, making it more impactful[1][2][3].

Hinge Design and Crease Visibility
The Z Fold 5 features a redesigned hinge that allows it to fold completely flat, reducing the gap between the two screens when closed. This design change not only improves aesthetics but also minimizes potential debris accumulation. While both models still exhibit a crease in the middle of the inner display, the crease on the Z Fold 5 is reportedly less noticeable due to this new hinge design[1][3][4].

Durability Enhancements
In terms of durability, the Z Fold 5 uses Gorilla Glass Victus 2 for its outer protection, compared to Gorilla Glass Victus+ on the Z Fold 4. This upgrade provides better scratch resistance and overall durability for everyday use[2][3].

In summary, while both devices maintain similar display sizes and resolutions, the Galaxy Z Fold 5 offers notable improvements in brightness, hinge design, and durability, enhancing the overall user experience compared to its predecessor.
