RGBW may refer to: Red, green, blue and white * RGBW sensor, a color filter array * RGBW, an LED strip light with four channels * RGBW color wheel, in a DLP projector * PenTile RGBW, in the PenTile matrix family * RGBW sub-pixels, in WhiteMagic display technology Other uses * Royal Gloucestershire, Berkshire and Wiltshire Regiment, a former regiment of the British Army See also * RGB The RGB color model is an additive color model in which the red, green and blue primary colors of light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three addi ...

Color Filter Array
In digital imaging, a color filter array (CFA), or color filter mosaic (CFM), is a mosaic of tiny color filters placed over the pixel sensors of an image sensor to capture color information. The term is also used in reference to e paper devices where it means a mosaic of tiny color filters placed over the grey scale display panel to reproduce color images. Image sensor overview Color filters are needed because the typical photosensors detect light intensity with little or no wavelength specificity and therefore cannot separate color information. Since sensors are made of semiconductors, they obey solid-state physics. The color filters filter the light by wavelength range, such that the separate filtered intensities include information about the color of light. For example, the Bayer filter (shown by the image) gives information about the intensity of light in red, green, and blue (RGB) wavelength regions. The raw image data captured by the image sensor is then converted to a fu ...

LED Strip Light
An LED strip light (also known as an LED tape or ribbon light) is a flexible circuit board populated by surface mounted light-emitting diodes (SMD LEDs) and other components that usually comes with an adhesive backing. Traditionally, strip lights had been used solely in accent lighting, backlighting, task lighting, and decorative lighting applications. Increased luminous efficacy and higher-power SMDs have allowed LED strip lights to be used in applications such as high brightness task lighting, fluorescent and halogen lighting fixture replacements, indirect lighting applications, ultraviolet (UV) inspection during manufacturing processes, set and costume design, and even growing plants. Beginning in 2021, LED lighting in the form of ''"Flex neon"'' is starting to replace neon sign lighting. Design Variables in strip lighting consist of water resistance, color, adhesives, choice of SMD, driving voltage, control type, and whether it is constant current or constant voltage layou ...

DLP Projector
Digital Light Processing (DLP) is a set of chipsets based on optical micro-electro-mechanical technology that uses a digital micromirror device. It was originally developed in 1987 by Larry Hornbeck of Texas Instruments. While the DLP imaging device was invented by Texas Instruments, the first DLP-based projector was introduced by Digital Projection Ltd in 1997. Digital Projection and Texas Instruments were both awarded Emmy Awards in 1998 for the DLP projector technology. DLP is used in a variety of display applications from traditional static displays to interactive displays and also non-traditional embedded applications including medical, security, and industrial uses. DLP technology is used in DLP front projectors (standalone projection units for classrooms and business primarily), DLP rear projection television sets, and digital signs. It is also used in about 85% of digital cinema projection, and in additive manufacturing as a light source in some printers to cure resins ...

PenTile Matrix Family
PenTile matrix is a family of patented subpixel matrix schemes used in electronic device displays. PenTile is a trademark of Samsung. PenTile matrices are used in AMOLED and LCD displays. These subpixel layouts are specifically designed to operate with proprietary algorithms for subpixel rendering embedded in the display driver, allowing plug and play compatibility with conventional RGB (Red-Green-Blue) stripe panels. Overview "PenTile Matrix" (a neologism from wiktionary:penta-, penta-, meaning "five" in Greek and tile) describes the geometric layout of the prototypical subpixel arrangement developed in the early 1990s. The layout consists of a quincunx comprising two red subpixels, two green subpixels, and one central blue subpixel in each unit cell. It was inspired by biomimicry of the human retina which has nearly equal numbers of L and M type cone cells, but significantly fewer S cones. As the S cones are primarily responsible for perceiving blue colors, which do not appre ...

WhiteMagic
WhiteMagic is a display technology developed by Sony and first used in Sony Xperia P. It adds one more white subpixel to conventional RGB pixel, making every pixels consists of RGBW sub-pixels. Display technology Sony claims that as white sub-pixel have higher light-penetrating capability, it can provide same level of brightness with fewer back-lit, and thus able to save energy. The display becomes up to twice as bright and up to twice as power efficient when using this technology. It totally eliminates the problem of sunlight visibility, providing the most clear sunlight legibility while saving power and not causing any heating problems. Traditional LCDs can save a lot of power by displaying mostly black and white colors but a LCD with WhiteMagic one can save even 50% more power using those colors... Sony dedicated a tiny blog post to this, while more detailed ones can be found too. The technology had also been showcased by other companies like Japan Display. With WhiteMagic, ev ...

Royal Gloucestershire, Berkshire And Wiltshire Regiment
The Royal Gloucestershire, Berkshire and Wiltshire Regiment was a short-lived infantry regiment of the British Army. History The regiment was formed in 1994 by the amalgamation of the Gloucestershire Regiment and the Duke of Edinburgh's Royal Regiment (Berkshire and Wiltshire). It was the only regiment in the British Army whose members were permitted to wear a cap badge on both the front and the rear of their headdress. The back badge was awarded to the 28th Regiment of Foot for their actions at the Battle of Alexandria in 1801 when the regiment fought on whilst completely surrounded by the enemy. The regiment was also unique in the British Army in that it was permitted to wear the United States Presidential Unit Citation, which it inherited from the 1st Battalion, Gloucestershire Regiment which was awarded for their defence of Gloster Hill during the Battle of the Imjin River in April 1951 during the Korean War. Between 2002 and 2005, the 1st Battalion, Royal Gloucestershir ...
