AMOLED screen or IPS LCD panel, which is better?

  As we can see, AMOLED displays are currently in the limelight, and people like AMOLED screens over LCD screens for no other reason than - more vibrant colors, brighter screens, and easier to catch the eye. The AMOLED screen is currently used in many popular models, for example, Samsung Galaxy S4, Samsung Galaxy S3, and Nokia Lumia 925. but the mobile phone industry is rapidly changing, in fact, with the LG Optimus G Pro with Full HD IPS LCD panel after the stunning debut of the AMOLED screen dominance of the situation feels like it is being broken.


  The current mobile phone screen variety, display effects vary, but ultimately they are only the above-mentioned screen material LCD and OLED (Nokia Lumia 928 using OLED material) two, then what is the difference between these two materials? In the end, which kind of screen is better? Let's look at the AMOLED screen and IPS screen from a science perspective.


What is an OLED material screen? What is an AMOLED panel? What is Super AMOLED technology?


  OLED: Organic Light Emitting Display, organic light-emitting display, mobile phone LCD belongs to the newly emerging species, known as "dream display". Organic materials are coated and glass substrates that glow when an electric current is passed through them. And OLED display screen can be made lighter and thinner, viewing angle, and can significantly save electricity. However, although the future technology is better OLED will replace the TFT and other LCD, but organic light-emitting display technology there are short life, large-scale screen difficult defects. The AMOLED series of panels developed by Samsung is the use of OLED material screen.



  AMOLED: Abbreviation for Active Matrix/Organic Light Emitting Diode, which can be translated as Active Matrix Organic Light Emitting Diode Panel. Compared with traditional LCD panels, AMOLEDs have faster response speed, higher contrast ratio, and wider viewing angle.


  Super AMOLED: AMOLED technology, also known as "Super Active Matrix Organic Light Emitting Diode" or "Advanced AMOLED Display Technology," is currently promoted by Samsung Electronics Co. smartphones, tablets. The main difference from other display technologies is that touch is actually operating on the panel, without the need to penetrate the air layer. The advantages of Super AMOLED over AMOLED are a brighter screen, reduced sunlight reflection, and lower power consumption.


                               


What is LCD screen? What is IPS technology?


  LCD is the abbreviation of Liquid Crystal Display, which includes TFT, UFB, TFD, STN, and other types of liquid crystal display, LCD structure is placed in two parallel glass substrate liquid crystal box, the lower substrate glass set TFT (thin-film transistor), the upper substrate glass set on the color filter, through the TFT on the signal, the liquid crystal display can be used in the liquid crystal display. The principle of LCD display determines its viewing angle is not ideal, when the backlight source through the polarizer, liquid crystal, and orientation layer, the output light has a directional. That is, most of the light is emitted vertically from the screen, so from a larger angle when viewing the LCD monitor, you can not see the original color, or even only see all white or all black. In order to solve this problem, manufacturers have developed IPS technology, which is claimed to allow up and down left and right viewing angle of 170 degrees.


  IPS is the abbreviation of In-Plane Switching, which translates to plane conversion, this technology is Hitachi launched in 2001 the LCD panel technology, commonly known as "Super TFT". The biggest feature of the IPS panel is that its poles are on the same surface, unlike other liquid crystal mode electrodes are on the top and bottom of the two sides, three-dimensional arrangement. The technology to the liquid crystal molecules arranged in an optimized way, to take the horizontal arrangement, when encountering external pressure, the molecular structure down slightly sagging, but the overall molecules were also horizontal. When encountering external forces, the solidity and stability of the molecular structure of hard screen liquid crystal are far better than the soft screen! So will not produce screen distortion and affect the screen color, which can maximize the protection of the screen effect is not damaged.


                                       


The biggest difference between LCD screen and OLED screen?


  In fact, the most fundamental difference between LCD and OLED is that OLED is self-emitting, while LCD needs to be irradiated by a backlight plate to be displayed. But whether it is based on OLED material AMOLED screen or an improved version of LCD IPS screen, due to the different working principles, they all have their own advantages.


The advantages of AMOLED


  Compared with traditional LCD, AMOLED screen is very thin and can be integrated into the screen touch layer, to make the ultra-thin machine has more advantages.


  AMOLED self-lighting, a single-pixel does not work when displaying black, and low power consumption when displaying dark colors.


  AMOLED can be used as a flexible screen, compared to the glass substrate of the LCD screen should not be damaged.


  4. AMOLED and SUPER AMOLED color gamut are very wide, which can reach 110% NTSC. some colors that cannot be accurately reproduced on LCD can be expressed on AMOLED. For example, the full-blown rape blossom, to wu yuan have the feeling, in the ordinary LCD is not displayed, because beyond the color gamut range of the display. In order to solve this problem, Sharp's high-grade LCD deliberately increases the yellow sub-pixel to express the vivid yellow.


  AMOLED has high contrast, theoretically, the contrast can be infinite, and will not leak light.


  AMOLED has a very fast response speed, the response time is only 1/1000 to 1/100 of LCD.


Advantages of IPS


  1, fast response, consumers in a long time to enjoy high-speed sports screen, IPS hard screen can ensure clear, smooth, and realistic results, eye irritation is significantly reduced, in full compliance with the health claims.


  2, large viewing angle, the angle of view of the IPS hard panel can reach 178 degrees. The degree of color change that occurs when watching from the front and different angles is called the color distortion rate, and the results show that the values derived from the IPS hard screen are almost indistinguishable with the naked eye, which means that the effect is the same when watching the screen from the front or the side.


  3, true and accurate color, IPS hard screen, excellent color inversion and brightness conversion, and other properties, so that you can enjoy no matter from which angle you watch, can enjoy the bright, saturated, natural picture of the ideal. In addition, the IPS has very high contrast, a pure black level more clearly, so the design professionals through the use of the field, it is generally believed that the IPS hard LCD effectively narrowed the design and the final product of the error between the sample.


  4, screen stability, touch no waterline. As a result of the unique horizontal IPS hard-screen molecular structure, so that when touched without watermarks, shadow, and flash phenomena, very stable, and therefore extremely suitable for the touch function of the TV and public display devices.


  5, environmental protection and energy-saving, IPS hard screen technology will creatively arrange the liquid crystal molecules horizontally, reducing the thickness of the liquid crystal layer, thereby changing the light transmittance of the liquid crystal screen. In addition, IPS hard screen using bipolar drive technology, so that the pixel opening rate increased by 25%. As a result of increased light transmission, the IPS hard screen used in LCD TVs can reduce the power of the backlight, thus achieving an energy-saving effect.


                                        


In fact, the proposition of which is better has always been a matter of opinion. For users, no matter it is IPS screen or AMOLED screen, as long as it can bring shocking visual effects is a good screen. Users can make their choice according to their own preferences.
