DMD Image Specification

1. SCOPE

This document specifies the image quality requirements applicable to the XGA RGBW Palmtop Configuration F Component Kit. The Component Kit provides the XGA RGBW Palmtop Projector with Digital Imaging functionality based on Digital Micromirror Device (DMD) technology.

2.Definitions

2.1Blemish

A blemish is an obstruction, reflection, or refraction of light that is visible, but out of focus in the projected image under specified conditions of inspection (see Table 1). It is caused by a particle, scratch, or other artifact located in the image illumination path.

2.2Dark pixel

A dark pixel is a single pixel or mirror that is stuck in the OFF position and is visibly darker than the surrounding mirrors.

2.3Bright pixel

A single pixel or mirror that is stuck in the ON position and is visibly brighter than the surrounding mirrors.

2.4Unstable pixel

A single pixel or mirror that does not operate in sequence with parameters loaded into memory. The unstable pixel appears to be flickering asynchronously with the image.

2.5Adjacent

Two or more stuck pixels sharing a common border or common point , also referred to as a cluster .

2.6Streaks

Artifact resulting from localized variation in mirror tilt angle relative to surrounding mirrors . They are similar in appearance to window scratches but appear at the mirror

Level . Streaks appear as faint diagonal or arcing patterns in the image.

2.7Sea of Mirrors ( SOM )

SOM is a rectangular array of off-state mirrors surrounding the active area.

2.8Eyecatcher

A small localized light “spot” which haas high spatial frequency and high differential

Brightness. These are due to various DMD window or window aperture “defects” Including : digs , voids , particles and scratches.

BenQ PB6100, PB6200 manual DMD Image Specification

PB6200, PB6100 specifications

The BenQ PB6100 is a versatile and user-friendly projector designed for both home and office use. As an entry-level projector, it provides impressive specifications, making it ideal for presentations, movie watching, and educational purposes.

One of the standout features of the BenQ PB6100 is its brightness. With a luminous output of up to 3,200 ANSI lumens, it can perform well even in well-lit environments. This ensures that images remain vibrant and clear, regardless of the ambient lighting conditions. Paired with a 2000:1 contrast ratio, the PB6100 delivers sharp and detailed images, allowing for enhanced color accuracy and depth.

The PB6100 employs DLP (Digital Light Processing) technology, which is known for its reliability and image quality. This technology utilizes a digital micromirror device that creates images with remarkable clarity and precision. The DLP design also ensures fewer maintenance issues, as it is less susceptible to dust accumulation compared to other projector types.

Another notable characteristic of the BenQ PB6100 is its resolution capability. It supports a native SVGA resolution of 800 x 600 pixels, which is suitable for basic presentations and video playback. It also supports various aspect ratios, including 4:3 and 16:9, providing flexibility depending on the content being presented.

In addition to its performance features, the PB6100 offers several connectivity options. It is equipped with multiple input ports, including VGA, USB, and composite video, allowing users to connect various devices such as laptops, desktops, and DVD players. This wide range of connections enhances the projector’s versatility in different setups.

Portability is another attribute of the BenQ PB6100. Designed to be lightweight and compact, it is easy to transport for off-site meetings or home entertainment.

The projector also has built-in speakers, which provide decent sound output, eliminating the need for additional audio equipment in casual viewing settings.

In summary, the BenQ PB6100 blends functionality with user-centric designs, making it an exceptional choice for those seeking an affordable projector without compromising on quality. Its features, such as high brightness, DLP technology, variety of connectivity options, and portable design, position it as a solid option for any user looking to enhance their visual experience.
