aperture grille

Another approach is the aperture grille, better known by its trade name, Trinitron.

Aperture grilles do not exhibit this behavior; when the wires heat up, they expand vertically.

Sony eventually abandoned it in favor of their famous Trinitron system using an aperture grille.

Another advantage of the aperture grille was that the distance between the wires remained constant vertically across the screen.

Another type of color CRT uses an aperture grille to achieve the same result.

Aperture grille only has horizontal 'dot pitch', or otherwise known as 'stripe pitch'.

These stabilizing wires provide the easiest way to distinguish aperture grille and shadow mask displays at a glance.

The vertical wires in the aperture grille meant that the tube had to be nearly flat vertically; this gave it a unique and appealing look.

Sony's attempt to produce a practical Chromatron inspired the development of their Trinitron aperture grille system.

(The shadow mask or aperture grille had to be removable and accurately re-positionable for this process to succeed.)

The Trinitron design incorporates two unique features: the single-gun three-cathode picture tube, and the vertically aligned aperture grille.

The combination of three-in-one electron gun and the replacement of the shadow mask with the aperture grille resulted in a unique and easily patentable product.

Additionally, aperture grille displays tend to be vertically flat and are often horizontally flat as well, while shadow mask displays usually have a spherical curvature.

Super Fine Pitch refers to Sony's line of Trinitrons with high horizontal resolution and very fine aperture grille stripe pitch.

They are packed together in stripes (as in aperture grille designs) or clusters called "triads" (as in shadow mask CRTs).

Aperture grille A tube construction method that uses a grille of very fine wires in front of the phosphor face plate instead of a conventional shadow mask.

The Trinitron combined the vertical stripes of the beam-index and Chromatron tubes with a new single-gun three-beam cathode and an aperture grille shadow mask.

CRTs can emit a small amount of X-ray radiation as a result of the electron beam's bombardment of the shadow mask/aperture grille and phosphors.

Cromaclear is an improvement of the aperture grille technology, pioneered by the NEC Corporation; one of its advantage is the lack of the damping wires.

(A magnetized aperture grille has a similar effect, and everything stated in this subsection about shadow masks applies as well to aperture grilles.)

In smaller CRTs, these strips maintain position by themselves, but larger aperture grille CRTs require one or two crosswise (horizontal) support strips.

Dot (or aperture grille) pitch The distance between adjacent dots (or stripes on an aperture grille tube) of the same color phosphor.

The 'shadow mask' is one of two major technologies used to manufacture cathode ray tube (CRT) televisions and computer displays that produce color images (the other is aperture grille).

The electrons from the cathodes are all aimed toward a single point at the back of the screen where they hit the aperture grille, a steel sheet with vertical slots cut in it.

While many considered aperture grille technology to produce superior images, advances in shadow mask and hybrid technologies since the 1990s have made people's preferences more a matter of personal choice or specific application.
