Liquid Crystal (LC)

LC stands for Liquid Crystal (sometimes also referred to as liquid crystal fluid or LC fluid, although technically redundant).  The defining thing about Liquid Crystals used in displays is that the polarization of the fluid can be changed by an electric field. This changing polarization can be used to make a dark or clear area … Read more Liquid Crystal (LC)

nits

What are nits? Essentially, nits are a measure of brightness. Of course, there’s more: A nit is a unit of a display’s luminance. The SI unit  is the candela per square meter (cd/m2). One nit is one cd/m2. A candela is the SI unit for luminous intensity and one candela approximately equals the intensity of … Read more nits

OLED

OLED stands for Organic Light Emitting Diode. OLEDs are used to make OLED Displays, which can either be PMOLED (Passive Matrix OLED) or AMOLED (Active Matrix OLED). Crystalfontz carries a full line of OLED modules. Detailed Definition What makes OLEDs useful for display construction is that they can be fabricated in bulk. For instance, to … Read more OLED

PLED

PLED stands for Polymer Light Emitting Diode. PLEDs are also called P-OLEDs. Crystalfontz briefly carrier some PLED displays, however the poor shelf lifetime of these displays (1-2 years)led us to discontinue the displays. Many of the PLED modules we offered have drop in OLED or LCD replacements. Get in touch with our support team for … Read more PLED

PMOLED

PMOLED is Passive Matrix OLED — Passive Matrix Organic Light Emitting Diode. Passive Matrix refers to the arrangement of the driving electrodes in the OLED display. In PMOLED displays, there is an array of horizontal conductors and an array of vertical conductors, with the OLED material between them. A pixel is formed where the vertical … Read more PMOLED

PWM

PWM stands for Pulse Width Modulation. Pulse width modulation describes a method of sending a signal as a pulse in order to drive analog components at varying power levels. By changing the width of the pulse, a smaller amount of power is delivered each period. Pulse width modulation is used to control the brightness of … Read more PWM

R5G6B5 or 565

R5G6B5 or 565: A method of storing a full-color pixel in a single 16-bit word of memory. For each pixel, the red and blue channels can take on 32 levels, encoded as 5 bits each. The green channel can take on any of 64 levels, encoded as 6 bits. Theoretical color depth is 216 or … Read more R5G6B5 or 565

RAM

RAM stands for Random Access Memory. This is memory that may be written to some value, then later read. RAM is the normal memory in a computer system. RAM only holds data when the RAM is powered. If power is interrupted, the data stored in the RAM is lost.
