Glossary: M, N, O; Laptop & Laptop LCD Screen Industry Definitions

Home » Resource Center » Glossary

ScreenTek is proud to provide you this glossary of common terms in the laptop LCD screen industry, and in the laptop notebook industry. Feel free to become more familiar with the terms we use throughout our site. If you notice any glaring omissions, we'd be glad to hear about those. Drop us a line at sales@screentekinc.com.

M, N, O Terms » 16 definitions


is a layer applied in the manufacturing of an active matrix TFT LCD device.

(more terms)

matrix addressing

display runs control signals only to the rows and columns of the display. For a screen size of mn pixels, this scheme would require m+n control signals.

(more terms)

Mirror projection aligner

is provided wherein the image position can be shifted by employing a bending mirror which makes a slight change in the magnification

(more Hardware terms)

Module Assembly Process

The process of assembling the LCD cell, driver circuits, backlight, frame and other components into a finished display panel. This is the third and final major process group in the manufacturing of an LCD.

(more terms)


Only displaying one color or multiple shades of a single color. Also, refers to a black and white display.

(more Image terms)


A Japanese word meaning "blemish" that has become widely used in the display industry to describe non-uniform areas on an LCD display. Muras range tremendously in size, shape and severity, which makes them very hard to categorize. Muras are generally considered to be defects in the LCD.

(more terms)

N+ layer

A heavily doped (N+) region directly under the N doped epitaxial collector region of transistors in a monolithic integrated circuit used to lower the series collector resistance

(more terms)

National Television System Committee (NTSC)

NTSC is the analog television system used in the US, Canada, Japan, South Korea and many other countries. The significance of NTSC to the display industry is that the 1953 NTSC standard defined a color gamut that is still in use today. For example, standard monitor LCDs today can display about 72% of the NTSC gamut, while 32" TV LCDs with LED backlights can display about 105% of the NTSC gamut.

(more terms)


An LCD screen which has not been used.

(more Quality terms)

New Pull

An LCD screen which has been removed from a laptop that has not been used.

(more Quality terms)


Unit of luminance. 1 nit = 1 candela / square meter; or, 1 nit = 1 cd/m2. It's a measure of brightness for computer monitors, flat panel displays, and LCD screens. Nit is not an SI unit of measure; the SI unit for luminance is candelas per square meter.

(more Optics terms)

Normally white TN mode

LCD device includes a first optical compensation film between a light-incident-side polarization film and an LC cell, and a second optical compensation film between a light-emitting-side polarization film and the LC cell. The optical axis of the first (second) optical compensation film projected onto the substrate surface is substantially parallel to the longer axis of an equivalent refractive index ellipsoid of a residual retardation of the LC layer in the vicinity of a light-incident-side (light-emitting-side) substrate upon display of black color.

(more Hardware terms)

Notebook panel

This would be the actual LCD/LED screen located within the upper assembly of your laptop.

(more Quality terms)


A unit of electrical resistance equal to that of a conductor in which a current of one ampere is produced by a potential of one volt across its terminals.

(more Electronic terms)

Optical Density

where I is the intensity of light at a specified wavelength ? that has passed through a sample (transmitted light intensity) and I0 is the intensity of the light before it enters the sample or incident light intensity (or power)

(more terms)

Organic Light-Emitting Diode (OLED)

A special type of light-emitting diode in which the light-emitting layer is comprised of thin films of organic compounds. The "D" in OLED is also interchangeably used to mean "Display", in which case an OLED is an emissive flat-panel display where the frontplane contains organic light-emitting elements and the backplane is either a passive matrix (PMOLED) or active matrix (AMOLED) control structure. There are two basic types of organic compounds used in OLEDs, small-molecule (SMOLED) and polymer (P-OLED or PLED).
