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 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

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 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.


A reflective LCD depends on having sufficient ambient light to reflect in order to be read. A reflective LCD does not have a backlight and does not make any light on its own.   A reflective LCD can be seen well in any lighting situation where you could read text on a paper, they are … Read more Reflective


ROM stands for Read Only Memory. This is memory that is factory pre-programmed to hold some data. ROM is data that can be read, but cannot be written or changed.
