Introduction:
In liquid crystal displays, a crucial parameter is resolution, and there are various types of resolutions available. High Definition (HD) and Full High Definition (FHD) are two commonly used terms to describe screen resolutions, and they have a significant impact on the quality of our visual experiences. But what do these terms exactly mean? How do you make a choice between them?
What are HD and FHD?
HD: 720P
HD, short for High Definition, refers to images or videos with a vertical resolution equal to or greater than 720P (1280×720 resolution), which means 1280 pixels horizontally and 720 pixels vertically.
FHD: 1080P
FHD stands for Full High Definition, often abbreviated as 1080P. Full High Definition screens typically have a resolution of 1920×1080 pixels.
What is PPI?
Pixels Per Inch (PPI) is a unit of pixel density, representing the number of pixels per inch on a screen. Higher PPI values indicate greater pixel density and, consequently, higher fidelity in display.
How to Choose Between HD and FHD Screens:
HD: Currently, HD screen assemblies on the market have a PPI value of around 300, which is not significantly different from the 326 PPI of the original iPhone screen.
FHD: FHD screen assemblies offer superior display quality compared to HD screens and are typically priced higher.
In addition to screen resolution, factors like screen brightness, white balance, color gamut, and viewing angles are key determinants of screen quality.
Is Higher Screen Resolution Always Better?
Higher screen resolution does indeed translate to better display quality. Apart from HD and FHD, there are also screens with QHD and 4K resolutions available in the market. However, higher resolution comes with higher power consumption and places a heavier load on the processor. For smartphone screens, at a viewing distance of 20cm, the difference in visual acuity between 1080p and 2K is not significant, making FHD sufficient.
