the color of super AMOLED is slightly cold.
TFT is produced by different manufacturers.
the batches are different.
the color of super AMOLED is slightly coldWhen displaying colorful pictures, super AMOLED screen is better than other screens.
AMOLED screen is better than other screensThere is no difference between Samsung AMOLED screen and Sony SLCD screen in visual angle test.
in vertical display, Sony SLCD screen is better than Samsung AMOLED screen, but in horizontal screen mode, Samsung AMOLED screen is better than Sony SLCD screen.
in horizontal screen mode, Samsung AMOLED screen is better than Sony SLCD screenIt's said that IPS is a kind of TFT.
but iPhone3 is TFT.
iPhone4 is IPS, but I put my classmate's 3 and 4 together, and the difference is still very big.
because I just bought a mobile phone, which is AMOLED screen.
so I strongly suggest that the owner buy a mobile phone with AMOLED screen material, so that everyone is a brother in need, In fact,
which better proposition is always a matter of opinion.
for users, whether it's IPS screen, AMOLED screen or TFT screen.
as long as it can bring shocking visual effect, it's a good screen.
next, I'll introduce the principle, difference, advantages and disadvantages of the three kinds of screens.
in this article, I'll introduce the principle, advantages and disadvantages of the three kinds of screensWhat is OLED material screen? What is AMOLED panel? What is super AMOLED technology?OLED: organic light emitting display.
refers to organic light emitting display, which is a new emerging category in mobile phone LCD and known as "dream display"OLED display technology is different from traditional LCD display.
it does not need backlight, and uses very thin organic material coating and glass substrate. When current passes through, these organic materials will emit light.
moreover, OLED display screen can be made lighter and thinner.
the viewing angle is larger, and power can be saved significantly.
however.
although OLED with better technology will replace TFT and other LCDs in the future, However, organic light-emitting display technology still has some defects, such as short service life and difficulty in large-scale display.
the AMOLED series panel developed by SamSung company is made of OLED material.
this paper introduces the development of AMOLED series panelOLED structure diagramAMOLED: abbreviation of active matrix / organic light emitting diode.
can be translated as active matrix organic light emitting diode panel.
compared with the traditional liquid crystal panel.
AMOLED has the characteristics of faster reaction speed, higher contrast, wider viewing angle, etc.
AMOLED has the advantages of low cost, low cost and low costSuper AMOLED: the AMOLED technology vigorously promoted by Samsung Electronics at present.
also known as "super active matrix organic light emitting diode" or "advanced AMOLED display technology", it is mainly used in the use of mobile devices, such as smart phones, mobile phones, mobile phones, mobile phones, etc The main difference between tablet PC and other display technologies is that the touch control is actually operated on the panel.
it does not need to pass through the air layer.
compared with AMOLED,
Super AMOLED has the advantages of brighter screen, less sunlight reflection and lower power consumptionScreen structure of AMOLED and super AMOLEDWhat is LCD screen? What is iPS technology?LCD is short for liquid crystal displayIt includes TFT, ufb, TFD, STN and other types of liquid crystal displays.
the structure of LCD is to place a liquid crystal cell between two parallel glass substrates.
TFT (thin film transistor) is set on the lower glass substrate, and color filter is set on the upper glass substrate. The rotation direction of liquid crystal molecules is controlled by the change of signal and voltage on TFT, The display principle of LCD determines that the viewing angle is not ideal.
when the backlight passes through the polarizer, the liquid crystal and the orientation layer, The output light has directionality.
that is to say, most of the light is emitted vertically from the screen.
therefore, when viewing the LCD from a larger angle, you can not see the original color, or even can only see all white or all black.
in order to solve this problem.
manufacturers have developed iPS technology, It is claimed that it can make the up, down, left and right visual angle reach 170 degreesLCD structure diagramIPS is the abbreviation of in plane switching.
translated as planar conversion, this technology is a liquid crystal panel technology launched by Hitachi in 2001, commonly known as "super TFT."
we can see from the name.
in fact, IPS screen is a technology based on TFT, Its essence is still a TFT screen.
the biggest feature of IPS panel is that its two poles are on the same surface.
unlike other liquid crystal mode, the electrodes are arranged on the upper and lower sides in a three-dimensional way.
the technology optimizes the arrangement of liquid crystal molecules.
the horizontal arrangement is adopted. When encountering external pressure, the molecular structure is slightly depressed, but the whole molecule is still horizontalWhen encountering external force.
the firmness and stability of hard screen liquid crystal molecular structure is far better than that of soft screen! Therefore, it will not produce picture distortion and affect the picture color, and it can protect the picture effect from being damaged to the greatest extent.
in this way, it will not produce picture distortion and affect the picture colorIPS screen structure diagramIPS viewing angle rangeThe biggest difference between LCD screen and OLED screen?In fact, the most fundamental difference between LCD and OLED is that OLED is self luminous, while LCD needs to be illuminated by backlight panel to display.
however, no matter AMOLED screen based on OLED material or improved IPS screen of LCD.
due to different working principles, they all have their own advantages.
in this paper, the development of AMOLED screen based on OLED material is introducedAdvantages of AMOLED1. Compared with the traditional LCD.
AMOLED has a very thin screen, and can integrate a touch layer in the screen, so it has more advantages in making ultra-thin machine.
22. AMOLED is self luminous.
single pixel does not work when displaying black color, and low power consumption when displaying dark color.
when displaying dark color, AMOLED is self luminous3. AMOLED can be used as flexible screen.
compared with LCD screen on glass substrate, AMOLED should not be damaged4. AMOLED and super AMOLED have very wide color gamut.
they can reach 110% NTSC.
some colors that can't be accurately restored on LCD can be expressed on AMOLED.
for example, the blooming rape flowers.
the feeling of Wuyuan can't be displayed on ordinary LCD, Because it is beyond the gamut range of the display.
Sharp's high-end LCD screen is designed to solve this problem.
yellow sub-pixel is specially added to express bright yellow.
in order to solve this problem, sharp's high-end LCD screen is designed to add yellow sub-pixel5. AMOLED has high contrast.
theoretically, the contrast can be infinite,And no light leakage6. AMOLED has extremely fast response speed.
the response time is only 1 / 1000 to 1 / 100 of LCD.
the response time of AMOLED is only 1 / 1000 to 1 / 100 of LCDAdvantages of IPS1. The response speed is fast.
when consumers enjoy high-speed motion pictures for a long time, IPS hard screen can ensure clear, smooth and real effect, and the stimulation to eyes is significantly reduced, which is fully in line with the health demands.
the results show that iPS hard screen can ensure clear, smooth and real effect2. Large viewing angle.
the viewing angle of IPS hard screen panel can reach 178 degrees.
the degree of color change when viewing from the front and from different angles is called the color distortion rate.
the results show that the value of IPS hard screen can hardly be distinguished by naked eye, which means that the effect of viewing from the front or side is the same.
the results show that the value of IPS hard screen is almost indistinguishable from the naked eye3. The color is true and accurate.
IPS hard screen has excellent color reversal and brightness conversion performance, so that you can enjoy the ideal picture with bright, saturated and natural colors no matter from which angle you view it.
in addition.
IPS has very high contrast, and the pure black layer is clearer. Therefore, professionals in the design field can use the, It is generally believed that iPS hard screen LCD can effectively reduce the error between the design and the final product4. The picture is stable.
there is no water mark when touching.
due to the unique horizontal molecular structure of IPS hard screen,
there is no water mark, shadow and flash when touching, so it is very stable, so it is very suitable for TV and public display devices with touch function.
the design of IPS hard screen is simple and reliable5. Environmental protection and power saving.
IPS hard screen technology creatively arranges the liquid crystal molecules horizontally, reduces the thickness of the liquid crystal layer, and thus changes the light transmittance of the liquid crystal screen.
in addition.
IPS hard screen adopts bipolar driving technology, which increases the pixel opening rate by 25%.
IPS hard screen technology can improve the light transmittance of the liquid crystal screenDue to the increase of light transmittance.
the application of IPS hard screen in LCD TV can reduce the power of backlight, so as to achieve the effect of energy saving.
