AMOLED display and PMOLED display are two subtypes of OLED display technology based on an underlying principle of addressing pixels. The former stands for active matrix organic light-emitting diode or active matrix OLED while the latter corresponds to passive matrix OLED. What is the Difference Between AMOLED display and PMOLED display? What are Active Matrix […]

Difference Between OLED and AMOLED
An organic light-emitting diode or OLED display is a type of display technology based on electroluminescent organic compounds. These organic compounds essentially emit a particular frequency or color of light with the application of an electric current. On the other hand, an AMOLED stands for active matrix organic light-emitting diode. Hence, an AMOLED display is […]
LED Lamps vs. Fluorescent Lamps: Which One Is Better?
Fluorescent lamps started replacing incandescent lamps in the 1950s following the commercialization of the underlying fluorescence technology. These lamps soon dominated the market in the 1980s and the 1990s. On the other hand, light-emitting diode or LED lamps were under development as early as the 1960s, but these fixtures only produced light in the low […]
Advantages and Disadvantages of PNG Format
Portable Network Graphics or PNG is a file format for compressing digital images developed initially as an improved and non-patented replacement for Graphics Interchange Format or GIF. However, this format has now been used as a better replacement for the JPEG standard. The Advantages of the PNG Format 1. Lossless Compression: One primary advantage of […]
Advantages and Disadvantages of JPEG Standard
JPEG is a compression standard for digital images. Note that JPEG is an initialism for Joint Photographic Expert Group, an organization that created and maintains the JPEG, as well as the JPEG 2000, and JPEG XR standards. The standard has several file formats to include the JPEG Exchange Image File Format and JPEG File Interchange […]
The Three Factors of User Authentication
Websites and apps are increasingly utilizing layered authentication to promote security and privacy online. As a backgrounder, layered authentication is an identity and access management process that uses two or more layers based on the so-called factors of authentication. A user needs to present two or more factors to grand him or her access to […]
Hard Disk Drive vs. Solid-State Drive
Hard disk drive or HDD and solid-state drive or SSD are two major types of data storage device. Take note that phonographic recording and optical discs, as well as DNA-based storage, are other types of storage mediums and technology. However, HDDs and SSDs are more popular because of their reasonable manufacturing cost and better storage […]
Hard Disk Drive: Advantages and Disadvantages
Pros: The Advantages of HDD 1. One of the notable advantages of a hard disk drive or HDD is that it is cheaper when compared to a solid-state drive or SSD. An SSD with a similar storage capacity can be twice more expensive than an HDD. What this means is that computers with an HDD are […]
Solid-State Drive: Advantages and Disadvantages
A solid-state drive or SSD is one of the two major types of data storage device alongside a hard disk drive or HDD. Both HDDs and SSDs are more popular because of their reasonable manufacturing cost and better storage capacity. However, in choosing an SSD over an HDD, it is important to take note of […]
OLED vs. IPS LCD: Which One is Better?
Two display technologies currently dominate the consumer electronics market. These are organic light-emitting diode or OLED displays and in-plane switching liquid crystal display or IPS LCD. As a backgrounder, an OLED uses organic compounds that emit light in response to an electric current. On the other hand, an IPS is a specific type of LCD […]
