Super AMOLED explores the source of color display technology

Not long ago, a color blind artist named Harbison in the United Kingdom surgically implanted the chip into the back of the brain to add color to his world by "listening" to the unique vibration frequency of each color. Since the chip can be wirelessly connected to the Internet, he can receive images sent by mobile phones without seeing the real thing, becoming the first person in the world.

Super AMOLED explores the source of color display technology

Modern science and technology let color blind artists "listen" to color

Harbison proved by one's own "physical practice" that we are not "seeing" color, but "perceiving" color. Scientists pointed out that the human color perception information transmission path consists of four elements: light source, colored object, eye and brain. These four elements not only make people feel color, but also the conditions for people to correctly judge color. Among the four elements, if one of the problems occurs, the effect of color and color cannot be correctly judged.

Based on this principle, technicians constantly improve and improve display technology from the perspective of “light source” in order to provide people with more realistic and accurate color display effects.

Traditional LCD screens, including Retina screens, use "BackLight" technology. Simply put, its LCD panel itself does not emit light. The graphics and colors displayed are those of the LCD panel that modulate the backlight. result. At present, the most advanced Samsung Super AMOLED screen uses a completely different "self-illumination" technology. Its core is a very thin coating of organic materials. When there is current, these organic materials will emit light themselves. Display color without additional backlighting.

The Super AMOLED with self-illuminating source is better than the Retina screen with backlight. It can be summarized in four words: true, bright, wide and thin.

Super AMOLED with self-illuminating technology is the most advanced screen at present

True - color is closely related to light and shade. To show the real scene, the contrast range must be large enough to simultaneously represent extremely dark and bright common scenes, such as shadows in daylight, such as the lights in the night. The Retina screen with backlight can't be completely turned off (if the image is completely off, the image will not be displayed), the contrast is usually only 1000:1; on the contrary, the self-illuminating Super AMOLED screen can completely turn off the brightness of a single pixel, and the contrast is easy. More than 100,000:1, more than 100 times larger than the former, breaking through the huge limitations of the LCD screen in the performance of light and shadow contrast, color performance is "out of the box."

Bright - Obviously, the self-illuminating source is much more efficient than the backlight. Due to the refraction and loss of the backlight by the liquid crystal panel that cannot be illuminated, the Retina screen cannot exhibit the bright and transparent effect of the Super AMOLED panel. According to tests, the maximum brightness of the Super AMOLED screen is about 40% higher than that of the Retina screen, and the light reflectance is lower under strong light.

Wide--the spectrum produced by the backlight is a discontinuous spectrum, which causes many colors to be unrecoverable. The specific performance is that the color gamut is not wide enough, and usually only shows 70%-90% of the NTSC specification. Each pixel of Super AMOLED can be self-illuminated, covering a wide range of color gamut, which can reach 110% NTSC. Many colors that cannot be accurately restored on Retina screen can be easily expressed on Super AMOLED screen. .

The traditional display and the Super AMOLED display are fundamentally different in structure.

Thin - Actively illuminated Super AMOLED The dazzling screen itself does not require a backlight, so it has a great advantage in screen thickness, compared to the Retina screen, the thickness is much reduced. And Super AMOLED also uses a new process to seamlessly fit the display layer, touch sensing layer and outer glass layer, making it slimmer and more sensitive to multi-touch. Samsung GALAXY Tab S series tablet with Super AMOLED screen, the body thickness is only 6.6mm, is Samsung's thinnest tablet computer to date.
