__Pixel Density Formula:__

Pixel density (PD) refers to the number of pixels per unit area on a display screen, typically measured in pixels per square inches. It indicates the sharpness or clarity of an image on the screen. Higher pixel density results in finer detail and better image quality.

Pixel density – the total number of pixels per square inch of your screen.

Horizontal pixels per inch – the number of pixels lining up horizontally in one inch of the screen.

Vertical pixels per inch – the number of pixels stacked vertically in one inch of the screen.

While PPIw and PPIh represent pixel counts along each dimension, their product (PD) provides the overall pixel density.

Even if two screens have the same pixel density (PD), a larger screen with the same total number of pixels will appear less sharp due to the increased pixel spacing.

Pixel density, PD_{(p/in2)} in pixels per square inch is calculated by multiplying the horizontal pixel density, PPI_{w(p/in)} in pixels per inch by the vertical pixel density, PPI_{h(p/in)} in pixels per inch.

Pixel density, PD_{(p/in2)} = PPI_{w(p/in)} * PPI_{h(p/in)}

PD_{(p/in2)} = pixel density in pixels per square inches, p/in^{2}.

PPI_{w(p/in)} = horizontal pixel density in pixel per inch, p/in.

PPI_{h(p/in)} = vertical pixel density in pixel per inch, p/in.

- A display has a horizontal pixel density of 300 pixels per inch (PPI) and a vertical pixel density of 400 pixels per inch (PPI). Calculate the pixel density.

Given: PPI_{w(p/in)} = 300p/in, PPI_{h(p/in)} = 400p/in.

Pixel density, PD_{(p/in2)} = PPI_{w(p/in)} * PPI_{h(p/in)}

PD_{(p/in2)} = 300 * 400

PD_{(p/in2)} = 120000p/in^{2}.

- A display has a pixel density of 80,000 pixels per square inch and a horizontal pixel density of 200 pixels per inch. Calculate the vertical pixel density.

Given: PPI_{w(p/in)} = 200p/in, PD_{(p/in2)} = 80000p/in^{2}.

Pixel density, PD_{(p/in2)} = PPI_{w(p/in)} * PPI_{h(p/in)}

PPI_{h(p/in)} = PD_{(p/in2)} / PPI_{w(p/in)}

PPI_{h(p/in)} = 80000 / 200

PPI_{h(p/in)} = 400p/in.
