PenTile matrix is a family of patented subpixel matrix schemes used in electronic device displays. PenTile is a trademark of Samsung.

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.

It was inspired by biomimicry of the human retina which has nearly equal numbers of L and M type cone cellsbut significantly fewer S cones. As the S cones are primarily responsible for perceiving blue colors, which do not appreciably affect the perception of luminancereducing the number of blue nokia rgb stripe with respect to the red and green subpixels in a display nokia rgb stripe not reduce the image quality.

That is, that any given input pixel is mapped to either a red-centered logical pixel, or a green-centered logical pixel. PenTile was invented by Candice H. Samsung then funded a new company, Nouvoyance, nokia rgb stripe, Inc. The human eye is most sensitive to green, especially for high resolution luminance information. The green subpixels are mapped to input pixels on a one-to-one basis.

The red and blue subpixels are subsampled, reconstructing the chroma signal at a lower resolution. The luminance signal is processed using adaptive subpixel rendering filters to optimize reconstruction of high spatial frequencies from the input image, nokia rgb stripe, wherein the green subpixels provide the majority of the reconstruction. The red and blue subpixels are capable of reconstructing the horizontal and vertical spatial frequencies, but not the highest of the diagonal.

Diagonal high spatial frequency information in the red and blue channels of the input image are transferred to the green subpixels for image reconstruction. PenTile RGBW technology, used in LCD, adds an extra subpixel to the traditional red, green and nokia rgb stripe subpixels that is a clear area without color filtering material and with the only purpose of letting backlight come through, nokia rgb stripe, [17] hence W for white.

This makes it possible to produce a brighter image compared to an RGB-matrix while using the same amount of power, or produce an equally bright image while using less power. The PenTile RGBW layout uses each red, green, blue and white subpixel to present high-resolution luminance information to the human eyes' red-sensing and green-sensing cone cellswhile using the combined effect of all the color subpixels to present lower-resolution chroma color information to all three cone cell types.

Combined, this optimizes the match of display technology to the biological mechanisms of human vision. The display driver chip has an RGB to RGBW color vector space converter and gamut mapping algorithm, followed by metamer and subpixel rendering algorithms.

In order to maintain saturated color quality, nokia rgb stripe, to avoid simultaneous contrast error between saturated colors and peak white brightness, while simultaneously reducing backlight power requirements, nokia rgb stripe, the display backlight brightness is under control of the PenTile driver engine. When the image has very bright saturated colors, the backlight brightness is maintained at higher levels, nokia rgb stripe.

An ongoing controversy regarding the definition or measurement of resolution of color subpixelated flat panel displays led many people [25] [26] [27] to question the resolution claims of PenTile display products.

As a result, each pixel or group of subpixels can render any colour on the screen, regardless of neighbouring pixels. This is not the case with PenTile screens. Due to the one third lower subpixel density on PenTile displays [31] the pixel structure may be more visible when compared to RGB stripe displays with the same pixel density.

For a given size and resolution specification the PenTile screen can appear grainy, pixelated, speckled, with blurred text on some saturated colors and backgrounds when compared to RGB stripe color. In the RGBW case, nokia rgb stripe, this is caused as the W subpixel nokia rgb stripe not be available in order to maintain the saturated color. In the Nokia rgb stripe case, this effect will occur when the color boundary is primarily red or blue, as the fully populated one green per pixel sub-pixel cannot contribute, nokia rgb stripe.

For all other cases, text and especially full color images are effectively reconstructed. The PenTile layout reduces the number of subpixels needed to create a specified resolution. However the Samsung Galaxy S4 uses a PenTile Diamond Pixel array, where the green pixels are oval and repeat in a single line, while red and blue pixels are larger and alternate between the lines of green, ensuring nokia rgb stripe uniform colours with fewer aberrations compared to the earlier generation PenTile display on the Galaxy S III.

PenTile displays for smartphones have received a mixed reception. Nokia rgb stripe instance the Motorola Atrix 4G 's display had "inaccurate colours and poor viewing angles, not to mention practically unreadable text at its furthest zoom".

Nov 12,  · Yup, it's an RGB Stripe AMOLED, but our least favorite flavor, PenTile, but we found that whites arrive tinged with a slight blue-green haze, especially when comparing it . "PenTile Matrix" (a neologism from penta-, meaning "five" in Greek and tile) describes the geometric layout of the prototypical subpixel arrangement developed in the early s. 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.
