The dot pitch of a computer display determines the absolute limit of possible pixel density. Typical circa-2000 cathode-ray tube or LCD computer displays range from 67 to 130 PPI, though desktop monitors have exceeded 200 PPI, and certain smartphone manufacturers' flagship mobile device models have been exceeding 500 PPI since 2014.
The Parallel Peripheral Interface (PPI) is a peripheral found on the Blackfin embedded processor. The PPI is a half-duplex , bi-directional port that is designed to connect directly to LCDs , CMOS sensors , CCDs , video encoders (video DACs ), video decoders (video ADCs ) or any generic high speed, parallel device.
Various computer display standards or display modes have been used in the history of the personal computer. They are often a combination of aspect ratio (specified as width-to-height ratio), display resolution (specified as the width and height in pixels), color depth (measured in bits per pixel), and refresh rate (expressed in hertz ...
Retina display is a branded series of LCDs and OLED displays by Apple Inc. that have a higher pixel density than traditional displays. [1] Apple has registered the term "Retina" as a trademark with regard to computers and mobile devices with the United States Patent and Trademark Office and Canadian Intellectual Property Office.
The 8255 has a similar function to the Motorola 6820 PIA (Peripheral Interface Adapter) from the Motorola 6800 family, also originally packaged as 40-pin DIL. The 8255 provides 24 I/O pins with four programmable direction bits: one for Port A(7:0) (i.e., all pins in the port), one for Port B(7:0), one for Port C(3:0) and one for Port C(7:4).
The measure of how closely lines can be resolved in an image is called spatial resolution, and it depends on properties of the system creating the image, not just the pixel resolution in pixels per inch (ppi). For practical purposes the clarity of the image is decided by its spatial resolution, not the number of pixels in an image.
Key takeaways. Not to be confused with private mortgage insurance (PMI), mortgage protection insurance (MPI) helps cover your mortgage payment if you die or become disabled and can't work.
Some types of pixel layout showing how pixel pitch is measured. Dot pitch (sometimes called line pitch, stripe pitch, or phosphor pitch) is a specification for a computer display, computer printer, image scanner, or other pixel-based devices that describe the distance, for example, between dots on a display screen.
