What Is ALPD Laser Projector? And What Is ALPD?

An ALPD laser projector refers to projectors on the market that utilize ALPD technology.

It standing for Advanced Laser Phosphor Display, is a cutting-edge laser phosphor display technology.

How it works: In this technology, a blue laser is used to excite specific phosphorescent materials. When these materials are excited by the laser, they emit light of other colors (such as red and green). Combined with the original blue laser, this allows for the creation of a complete RGB color gamut, producing colorful projected images that emulate cinema-like visual effects.

If you’re unfamiliar with laser projectors, ALPD technology might sound complex……

Below, we’ll provide an introduction to laser projectors to help you better grasp the concept of ALPD technology.

Are Laser Projectors Worth It?

When classifying projectors based on their light source, there are primarily three types:

Traditional Lamp Projectors

Proiettori LED

Laser Projector

Lamp Projector:

Light Source: Utilizes traditional high-intensity bulbs or ultra-high-pressure xenon lamps.
Advantages: Lower cost and good color reproduction.
Disadvantages: Shorter lifespan, typically between 1,000-3,000 hours, requiring periodic replacement; gradual decline in brightness; takes time to start up and shut down; produces significant heat, potentially louder noise.

LED Projector:

Light Source: Uses LED lights as the light source.
Advantages: Compact, energy-efficient, fast start-up, bulb lifespan can exceed 20,000 hours with minimal replacement; good heat dissipation, low noise.
Disadvantages: Brightness is generally lower than traditional lamp and laser projectors; color saturation might be inferior to other technologies.

Laser Projector:

Light Source: Employs laser diodes or other laser technologies.
Advantages: High brightness, superior color saturation, high contrast ratio; fast start-up; lifespan can reach 20,000 hours or more; high energy efficiency.
Disadvantages: Initial purchase cost of laser projectors is high. Speckle may occur (a phenomenon unique to lasers, primarily due to the coherence of lasers. When lasers pass over certain object surfaces or through irregular media, lasers from different paths interfere coherently, producing alternating bright and dark spots, known as speckle).

Thus, ALPD technology is a laser light source technique, which not only makes images brighter and clearer but also extends the product’s lifespan and reduces the overall size of the device.

Recommended Portable Travel Laser Projector

Due to the absence of optical system technology, portable projectors have always been criticized for: small size, limited brightness, lack of contrast, and poor image clarity.

However, with the introduction of ALPD technology, even compact projectors can now deliver high-definition quality. Click on the product to learn more.

With the advancement of technology, there are now some portable, reasonably priced, and high-value laser projectors available, such as the Formoive S5, which is perfect for those new to laser projectors.

ALPD 4.0

Since the 4.0 version, ALPD technology has evolved from a Single Laser light source to a Triple Laser light source, resulting in significant improvements in color gamut, contrast, and light efficiency. In addition, ALPD 4.0 reduces blue light energy and flicker frequency, preventing radiation and fatigue, making it more beneficial for eye health.

Recommended Triple Laser Projector with ALPD 4.0 Technology

The Formovie Theater stands out as the sole projector supporting Dolby Vision, and it’s also the most budget-friendly among all triple laser projectors.

ALPD vs DLP: Which is better laser or DLP projector?

DLP (Digital Light Processing) is a display technology.

Working principle: In DLP projectors, the light emitted from a light source (which might be a traditional lamp, LED, or laser) is projected onto the DMD chip (a key component of DLP projectors). Depending on the image’s content, each tiny mirror will flip independently, reflecting light onto the screen or diverting it away.

ALPD is the light source for a projector, while DLP is a display technology. They are not the same thing; they are like the engine and gasoline of a car, not in conflict with each other.

A projector can use ALPD (laser) technology as its light source and can also choose DLP as its display technology.


When comparing laser light sources to LED light sources: Lasers generally offer higher brightness, suitable for larger venues or well-lit rooms, have a longer lifespan, usually between 20,000 to 30,000 hours or more, and produce more vibrant colors, but they generate more heat and might require better heat dissipation, and they tend to be pricier. On the other hand, LEDs have lower brightness, a lifespan around 20,000 hours, and while their color accuracy is good, it might not be as vibrant as lasers. They produce less heat and noise, are usually more affordable, and are suitable for home use or portable applications. The choice between these technologies depends on specific needs and budget.

What is the lifespan of a laser projector?

The lifespan of laser projectors typically ranges from 20,000 to 30,000 hours in full brightness mode. Some high-end models even claim lifespans exceeding 40,000 hours. It’s important to note that the actual lifespan may vary depending on usage conditions, the quality of the laser source, and manufacturer specifications.

Vantaggi della tecnologia ALPD

L'efficienza luminosa complessiva del proiettore digitale ALPD® è molto più elevata rispetto ad altre sorgenti luminose.

L'elevata efficienza luminosa porta a un'alta luminosità. Grazie all'impiego della tecnologia ALPD®, la luminosità raggiunge i 60.000 lm, mantenendo una posizione di leadership a livello mondiale.

Le prestazioni cromatiche soddisfano lo standard cinematografico DCI, con una gamma cromatica massima di 120% di Rec.2020.

I prodotti che utilizzano ALPD®4.0 possono raggiungere un rapporto di contrasto di 2500:1, superando di gran lunga gli standard cinematografici.

Il prodotto è stato sottoposto a diversi test sperimentali, tra cui test di invecchiamento, test di resistenza alla polvere (livello di protezione IP5X), test di dissipazione del calore, test di resistenza strutturale e test di temperatura e umidità elevate.
