In general there are 3 sub-pixels with in a pixel made up of red, blue and green. Newer monitors have included a 4th sub pixel adding yellow to the mix.

The smallest element of a screen is a pixel. A pixel is the smallest addressable element in a display device and is typically composed of red, green, and blue subpixels that combine to form a single color.
False. A dot on the screen that contains a color is called a "pixel."

A pixel (from PICture ELement)
Colors on a monitor are produced by mixing three primary colors (red, green, and blue) in varying intensities. Each pixel on the screen contains these three colored subpixels, and when they combine, they create different colors. By changing the intensity of each subpixel, the monitor can produce a wide range of colors.
There are several types of pixels, primarily categorized by their function and technology. Standard RGB pixels (red, green, blue) are the most common in displays, combining these colors to create a wide spectrum. Subpixels are smaller components of a pixel, often found in displays like LCDs, where each pixel consists of individual red, green, and blue subpixels. Additionally, there are photo-sensitive pixels in cameras, which capture light to create images, and quantum dots in advanced displays, enhancing color accuracy and brightness.
3 - Red, blue and green.

1 mega pixel how many pixel
The number of pixels on an LCD monitor depends on its resolution. Common resolutions include Full HD (1920x1080), which has approximately 2.1 million pixels, and 4K (3840x2160), which has around 8.3 million pixels. Higher-end monitors can have even greater resolutions, such as 5K (5120x2880) or 8K (7680x4320), offering significantly more pixels. Each pixel is made up of subpixels that create the full color display.
as a simple example assume you want divide a gray level secret image to two shares. Each pixel in the secret image is expanded to four subpixels in each share that consist of white and black so width and height of shares is twice of secret image. first share is an image wich has random pixels of black or white with equal probability. in second share, if corresponding pixel in main secret image is white then the pixel in second share is the same as first share and if pixel in the secret image is black, corresponding pixel in second share would be inverse of the same pixel in first share.
