Retina display who invented

Samsung isn't just "Samsung," though. It's a massive, multi-national conglomerate made up of more than 30 independent businesses, covering areas as disparate as life insurance and petrochemical engineering. One such free agent is Samsung Mobile Display. And, of course, while all this is happening, both companies compete fiercely to sell mobile phones and tablets as quickly as possible.

Samsung isn't the only company that manufactures displays for direct hardware competitors. LG and Sony -- both notable players in the Android phone and tablet space -- do it too.

To put it simply: It's complicated. As it stands, Samsung champions a display technology for its own mobile products that's currently of no appeal to Apple. Dubbed AMOLED shorthand for active-matrix organic light-emitting diode , Samsung has deployed this display tech in millions of mobile phones -- most notably, the Galaxy SII, the company's flagship Android device of The Galaxy Tab 7.

The "Super" variety of AMOLED integrates touch sensors directly in the surface glass of the screen, increasing brightness and reducing power consumption. In a sense, Samsung has a notable edge over competitors in the display space. The truth is that LG invented the Retina Display and Apple simply gave the display a name and then trademarked the name. When an Apple product has a Retina Display, each user interface widget is doubled in width and height to compensate for the smaller pixels.

Apple calls this mode HiDPI mode. The goal of Retina Displays is to make the display of text and images extremely crisp, so pixels are not visible to the naked eye. This allows displays to rival the smooth curves and sharpness of printed text and immediacy of photographic prints.

These better quality displays have been gradually released over a number of years, and the term is now used for nearly all of Apple products containing a screen, including Apple Watch, iPhone, iPod Touch, iPad, MacBook, MacBook Pro, and iMac. The average user can detect no graininess at all. Depending on the size of the screen on the product and the product itself, the pixels in a Retina display vary.

On the iPhone 4S , the Retina display had a pixel density of pixels per square inch while on the iPad the Retina display had a pixel density of pixels per square inch. The iPad was still considered to have a Retina display, however. The reason why it had a lower pixel density is that the normal viewing distance on an iPad is greater than that on an iPhone. People will generally hold their iPads farther away from their eyes than their iPhones. That means you can achieve the effect of a Retina display without using as many pixels.

Retina display resolution will also tend to vary. The iPhone X, for example, has a pixel density of pixels per square inch on its 5. This translates to a resolution of x pixels. The MacBook Pro inch model has a resolution of x pixels. The MacBook Pro 13 inches has a resolution of x pixels. The MacBook Pro 15 has a pixels per square inches and the MacBook Pro 13 has a pixel density of pixels per square inch.

These resolutions were larger than what you could get with many other regular screens. Samsung is a close competitor. It has a resolution of pixels by pixels and a pixel density of pixels per square inch. That is significantly more than what you get on the iPhone X and the images are consequently much crisper.

As for the Samsung S10 cellphone , the pixel density is about pixels per square inch, more than the pixel density on the iPhone X. The screen itself is still an LCD screen. The screen can produce it naturally.
