Projector Recommendations and Introduction

Projector Brightness Life

Generally, projectors use penetrating projection to present images. The bulbs can be divided into two types: metal bulbs and halogen bulbs. Metal bulbs have a lifespan of about 4000 hours, but their brightness will decline with time.

Projector Brightness Description

Projector lumens are a measure of brightness. The American National Bureau of Standards sets a standard for the number of lumens (relative brightness) of display devices, and the brightness measured by this standard is usually expressed in ANSI Lumens.

"Lumen" generally refers to the "luminous flux" defined by the American National Standards Institute.

(Total energy of light emitted by a light source per unit time) measurement standard, English is "lumen", abbreviated as "lm"

Refers to the indicator of the strength of the light energy emitted by the projector. Simply put, the higher the "lumen" number, the brighter the projector is.

Application Environment

Small and medium-sized conference rooms: recommended models below 4,000 lumens Large indoor events: recommended models with 5,000 lumens or more Outdoor night events: recommended models with 10,000 lumens or more

Projector Resolution Introduction

Screen resolution is the resolution that users feel when viewing images on the screen. Common settings are 640×480, 800×600, 1024×768, 1280×800, 1920*1080 (also known as 1080p), etc. The screen resolution is determined by the display chip in the machine.

It is not determined by the screen. Under a fixed screen size, when we adjust the screen resolution from 640×480 to 1024×768,

There must be more pixels on the screen, so the original image will look more detailed. The higher the screen resolution, the more detailed the image you see on the screen and the more realistic the colors.

Take "1024*768" as an example. Usually the first number represents the number of horizontal points, here means there are 1024 points, and the latter number means there are 768 vertical lines.
