What is the principle of a projection clock?

The principle of a projection clock mainly relies on projection technology, which displays time by projecting time information onto a wall or other surface. Specifically, the projection clock uses a bright red LED round light to illuminate the inverted white LCD screen, which displays time information. Then, the time information is magnified and projected onto the wall through two convex lenses. Clarity can be achieved by adjusting the distance between two convex lenses. ‌

The structure of a projection clock usually includes the following parts:

Light source: High brightness red LED round light, providing enough light to illuminate the LCD screen.

Image display component: A white LCD screen used to display time information.

Lens system: Two convex lenses are used to magnify time information and project it onto the wall.

Adjustment mechanism: Control the clarity of projection by adjusting the distance between two convex lenses.

The usage scenarios of projection clocks are very wide, and clocks can be enlarged or reduced according to user needs. The enlarged projection clock can be as spectacular as the big clock on the Bund in Shanghai, while the reduced one resembles a Roman numeral dial, suitable for different decorative styles and space requirements.
