question: Hiw do monitor/tv companies make so many pixels so quickly? Like some have millions and i could imagine that that would be quite diffacult to mass produce at the price that they are.
comment: I'm not sure I correctly understand your question. Most displays today are LEDs or OLEDs. The actual "pixels" on those displays are tiny pockets of a special liquid on a kind of plastic sheet/film. These sheets can be sort of "printed" and are mass produced by specialised companies. Many monitor/tv companies don't even make their own but buy from specialised parts suppliers which manufacture to their precise specifications. These suppliers can mass produce common display sheets at very high volumes and ever lower prices, because the "printing" process of production is continually being improved upon.
passages: Modern computer-monitors typically display about 72 to 130 pixels per inch (PPI), and some modern consumer printers can resolve 2400 dots per inch (DPI) or more; determining the most appropriate image resolution for a given printer-resolution can pose difficulties, since printed output may have a greater level of detail than a viewer can discern on a monitor. Typically, a resolution of 150 to 300 pixel per inch works well for 4-color process (CMYK) printing.
   On October 23, 2012, Ortus Technology Co., Ltd announced the development of the world's smallest 3840×2160 pixel LCD panel with a size of and a pixel density of 458ppi. The LCD panel is designed for medical equipment and professional video equipment.
  
  On October 25, 2012, LG Electronics began selling the first flat panel Ultra HD display in the United States with a resolution of 3840x2160. The LG 84LM9600 is a flat panel LED-backlit LCD display with a price of US$19,999 though the retail store was selling it for US$16,999.
   In April 2015, Videojet Technologies released their 1650 High Resolution (HR) and 1620 HR Continuous Inkjet (CIR) printers, said to be capable of printing sub-pixel size characters as small as 0.6mm in height (equivalent to 1.7007 points). The printers use a 40-micron nozzle that outputs more than 100,000 drops per second of ink. While these printers make microprinting faster and easier to produce digitally, they still have not reached the true sub-pixel size of less than 1 point.
  
  The smallest scale microtext a laser printer can produce is 0.5pt.

   The resolution for computer monitors has increased over time. From 320x200 during the early 1980s, to 1024x768 during the late 1990s. Since 2009, the most commonly sold resolution for computer monitors is 1920x1080. Before 2013 top-end consumer LCD monitors were limited to 2560x1600 at , excluding Apple products and CRT monitors. Apple introduced 2880x1800 with Retina MacBook Pro at on June 12, 2012, and introduced a 5120x2880 Retina iMac at on October 16, 2014. By 2015 most major display manufacturers had released 3840x2160 resolution displays.

   While some color printers can produce variable drop volumes at each dot position, and may use additional ink-color channels, the number of colors is still typically less than on a monitor. Most printers must therefore produce additional colors through a halftone or dithering process, and rely on their base resolution being high enough to "fool" the human observer's eye into perceiving a patch of a single smooth color.
   In addition, the transmission need not convey as high a resolution as would be needed for a larger display. MediaFLO streams are only 200-250 kbit/s, which would be insufficient for a larger screen size.
   Manufacturers often claim interpolated resolutions as high as 19,200 ppi; but such numbers carry little meaningful value, because the number of possible interpolated pixels is unlimited and doing so does not increase the level of captured detail.
   In 2005, Imperial Multimedia took on a kiosk project in Cedar Rapids, Iowa. The New Bohemia Solar Project is a collaboration between Iowa DNR, I-Renew, Alliant Energy, Thorland Company, and the City of Cedar Rapids, with funding provided by the United States Department of Energy. The purpose of this project was not only to provide 7200 watts of solar energy for Cedar Rapids' existing grid, but also to raise awareness and educate the public about the existence and benefits of solar energy.
   Scanning arrays were developed and used because of historical difficulties in fabricating 2-D arrays of sufficient size and quality for direct 2-D imaging. Modern FPAs are available with up to 2048 x 2048 pixels, and larger sizes are in development by multiple manufacturers. 320 x 256 and 640 x 480 arrays are available and affordable even for non-military, non-scientific applications.

   In 1996, Hand Held Products launched the first mobile computer with 2D imaging technology, the Dolphin 7200. In 1997, the Hand Held Product's Dolphin portable computer was selected by the United States Postal Service to be part of their own proof of delivery system, although a third party provided the manufacturing for this deal, which was the largest single order in the history of the industry – 300,000 units.
   10K resolution
  
  10K resolution is horizontal resolution of around 10,000 pixels. This resolution is expected to be used in computer monitors, and is not a standard format in digital television and digital cinematography, which feature 4K and 8K resolutions.

  On June 5, 2015, Chinese manufacturer BOE showed a 10K display with an aspect ratio of 64:27 (≈21:9) and a resolution of 102404320.
   BULLET::::- Lower cost in the future: OLEDs can be printed onto any suitable substrate by an inkjet printer or even by screen printing, theoretically making them cheaper to produce than LCD or plasma displays. However, fabrication of the OLED substrate is more costly than that of a TFT LCD, until mass production methods lower cost through scalability. Roll-to-roll vapour-deposition methods for organic devices do allow mass production of thousands of devices per minute for minimal cost, although this technique also induces problems in that devices with multiple layers can be challenging to make because of registration, lining up the different printed layers to the required degree of accuracy.
   The system was invented in 2005 by Christie Digital's Bob Rushby, chief technology officer, and Mike Perkins, senior product developer, while in a Tokyo hotel bar during a business trip.

  In 2007 the image quality of LCD televisions surpassed the image quality of cathode-ray-tube-based (CRT) TVs. In the fourth quarter of 2007, LCD televisions surpassed CRT TVs in worldwide sales for the first time. LCD TVs were projected to account 50% of the 200 million TVs to be shipped globally in 2006, according to Displaybank. In October 2011, Toshiba announced 2560 × 1600 pixels on a 6.1-inch (155 mm) LCD panel, suitable for use in a tablet computer, especially for Chinese character display.

   In spite of their legal success, Canon announced at the same time that the financial crisis of 2008 was making introduction of the sets far from certain, going so far as to say they would not be launching the product at that time "because people would laugh at them".
   Pixels per dollar – Similarly, Barry Hendy of Kodak Australia has plotted pixels per dollar as a basic measure of value for a digital camera, demonstrating the historical linearity (on a log scale) of this market and the opportunity to predict the future trend of digital camera price, LCD and LED screens, and resolution.
   At SID display week 2018, various companies showcased displays that are able to cover over 90% of the Rec.2020 color space. JDI showcased an improvement of their 17.3" LCD 8k broadcast monitor that is powered by an RGB laser backlight system. This allows the display to reproduce 97% of the Rec. 2020 color space.

   The resolution is also used in portable devices. In September 2012, Samsung announced the Series 9 WQHD laptop with a 13-inch 25601440 display. In August 2013, LG announced a 5.5-inch QHD smartphone display, which was used in the LG G3. In October 2013 Vivo announced a smartphone with a 25601440 display.
  
  Other phone manufacturers followed in 2014, such as Samsung with the Galaxy Note 4, and Google and Motorola with the Nexus 6 smartphone. By the mid 2010s, it was a common resolution among flagship phones such as the HTC 10, the Lumia 950, and the Galaxy S6 and S7.
   Due to the very high cost of building TFT factories, there are few major OEM panel vendors for large display panels. The glass panel suppliers are as follows:

   Although many manufacturers claim very high numbers, plasma displays, LCD displays, and CRT displays can deliver only a fraction of the contrast ratio found in the real world, and these are usually measured under ideal conditions. The simultaneous contrast of real content under normal viewing conditions is significantly lower.
   Japan's public broadcaster NHK was the first to start research and development of 4320p resolution in 1995. The format was standardized by SMPTE in October 2007, Interface standardized by SMPTE in August 2010 and Recommended as the international standard for television by lTU-R in 2012. Followed by public displays at electronics shows and screenings of 2014 Winter Olympics in Sochi and public viewings in February 2014 and the FIFA World Cup in Brazil in June 2014 using HEVC with partners AstroDesign and Ikegami Electronics.
   Candescent pushed ahead with development in spite of problems, breaking ground on a new production facility in Silicon Valley in 1998, partnering with Sony. However the technology was not ready, and the company suspended equipment purchases in early 1999, citing "contamination issues". The plant was never completed, and after spending $600 million on development they filed for Chapter 11 protection in June 2004, and sold all of their assets to Canon that August.

  Section::::Smallest Visible Pixel Size for a Hand Held Device.
  
  The smallest visible pixel size ("p") for a hand held device can be calculated assuming the screen is held at a comfortable distance (250mm) for someone with "normal" vision (able to see detail at a 1/60 degree angle):
  
  It can therefore be concluded that the pixel size for the Hitachi DX07 screen is only 5% greater than the smallest possible for practical use.
   NeXT MegaPixel Display
  
  The NeXT MegaPixel Display was a range of CRT-based computer monitors manufactured and sold by NeXT for the NeXTcube and NeXTstation workstations, designed by Hartmut Esslinger/Frog Design Inc.
  
  Section::::Description.
  
  The original MegaPixel Display was a monochrome 17" monitor displaying 4 brightness levels (black, dark gray, light gray and white) in a fixed resolution of 1120 x 832 at 92 DPI (just shy of a true Megapixel at 931,840 total pixels) at 68 Hz.
  
raw_presuppositions: Pixels are mass produced items. Difficult for tv companies to mass produce.
