Display
Equipped with a 4.5-inch TFT display, the Celkon A66 provides adequate screen real estate for basic browsing and app usage. The resolution of 480 x 854 pixels results in a pixel density of approximately 218 pixels per inch. While it may not offer the sharpest display, the screen serves general purposes effectively with decent color reproduction within its category. The screen-to-body ratio of 61.1% reflects a modest usage of the front panel for display, aligned with standard designs from its release period in 2014.
