AMOLED
AMOLED has many advantages over TFT LCD in terms of image quality, efficiency and cost.
this is also the reason why many large international companies still do not give up developing AMOLED, even though the yield is difficult to break through.
at present, they continue to invest in the development of AMOLED.

The difference between super AMOLED and ordinary TFT LCD screen is so simple

in addition to Sony, which has announced the launch time of its products, Toshiba, which has invested in Toshiba Panasonic display (TMD), has invested in the development of AMOLED, In terms of display performance, AMOLED has faster response speed, higher contrast and wider viewing angle, which are the inherent advantages of AMOLED over TFT LCD; In addition, AMOLED has the characteristics of self illumination, and does not need to use backlight, so it can be made thinner and lighter than TFT, and it can save power; Another more important feature is that AMOLED without backlight can save 3-4% of the cost of backlight module for TFT LCD.
AMOLED can be made into curved screen.
and the display image does not deform, which is conducive to the development of new display products.


AMOLED is indeed a very attractive product.
many international manufacturers like it, even the most popular product in the mobile phone market, iPhone, All of them are interested in AMOLED. I believe that after the yield rate is improved, the iPhone will also consider adopting AMOLED, especially the power saving features of AMOLED, which is very suitable for mobile phones. At present, the power consumption of AMOLED panel is only about 60% of that of TFT LCD, and there is still room for further decline of technology in the future.

of course, the biggest problem of AMOLED is the yield rate.
in the future, AMOLED panel power consumption is only about 60% of that of TFT LCDAt present, the price of AMOLED panel is 50% higher than that of TFT LCD, which is definitely a threshold for customers to adopt a large number of products. For Qijing, at this stage, it is still in the training period of yield adjustment, TFT screen - TFT screen
TFT (thin film transistor) is a kind of active matrix liquid crystal display.
it can "actively" control each independent pixel on the screen.
this can greatly improve the reaction time.
generally, the reaction time of TFT is relatively fast.
about 80 ms, Moreover, it has a large viewing angle, which can generally reach about 130 degrees, and is mainly used in high-end products.
the so-called thin film field effect transistor means that every liquid crystal pixel on the liquid crystal display is driven by a thin film transistor integrated behind it.
thus, it can achieve high speed, high brightness, high reliability and high reliability High contrast display screen information.
TFT belongs to active matrix liquid crystal display.
in technology, it adopts the "active matrix" mode to drive. The method is to use the transistor electrode made of thin film technology, and use the scanning method to "actively pull" to control the on and off of any display point. When the light source irradiates, it first penetrates upward through the lower polarizing plate, and uses liquid crystal molecules to conduct light, The purpose of display is achieved by shading and transmitting light.


TFT-LCD is a thin film transistor type LCD.
that is, true color (TFT).
TFT LCD has a semiconductor switch for each pixel.
each pixel can be directly controlled by point pulse, so each node is relatively independent,It can be continuously controlled, which not only improves the reaction speed of the display screen, but also precisely controls the color level of the display, so the color of TFT LCD is more true.
TFT LCD is characterized by good brightness, high contrast, strong sense of hierarchy, high brightness, high brightness, high contrast, high brightness, high brightness, high contrast, high contrast, high color level, high color level, high brightness, high contrast, high contrast, high contrast, high contrast The color is bright.
but it also has the disadvantages of relatively high power consumption and high cost.
TFT liquid crystal technology accelerates the development of mobile phone color screen.
many of the new generation of color screen mobile phones support 65536 color display.
some even support 160000 color display, when the high contrast of TFT, The advantage of rich color is very important.


TFT LCD mainly consists of: fluorescent tube, light guide plate, polarizing plate, filter plate, glass substrate, alignment film, liquid crystal material, thin mode transistor and so on.
.
TFT LCD has many advantages, such as low cost, low cost and low cost
