AMOLEDAMOLED has many advantages over TFT LCD in terms of image quality, efficiency and cost.

What's the difference between ordinary TFT screen and AMOLED screen?

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, AMOLED manufacturers continue to invest in developing AMOLED.
in addition to Sony, which has announced the time to market, Toshiba, which has invested in Toshiba Matsushita display (TMD), has made great progress in developing AMOLED, In addition, Panasonic, which develops its own products, and sharp, which claims to be not optimisticIn terms of display efficiency.
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 the cost of backlight module which accounts for 3-4% of 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 can be made into curved screenAMOLED is indeed a very attractive product.
many international manufacturers like it very much, and even the iPhone, the most popular product in the mobile phone market, is 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 60% of that of TFT LCD, In the future, there is still room for technology to decline further.
in the future, technology will continue to declineOf course, the biggest problem of AMOLED is the yield.
with the current yield, the price of AMOLED panel is 50% higher than that of TFT LCD,This is definitely a threshold for customers' willingness to adopt a large number of orders, and for Qijing, it is still in the training period of adjusting the yield rate at this stage, so it is not easy to accept a large number of orders.
this is the first time for QijingTFT screen - TFT screenTFT (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, and the viewing angle is large, which can reach about 130 degrees, It is mainly used in high-end products.
the so-called thin film field effect transistor (TFT).
refers to that every liquid crystal pixel on the liquid crystal display is driven by the thin film transistor integrated behind it.
so that the screen information can be displayed with high speed, high brightness and high contrast.
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, so as to achieve the purpose of display through shading and light transmissionTFT-LCD is a thin-film transistor 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 and can be continuously controlled, which not only improves the reaction speed of the display, but also precisely controls the display color level, So the color of TFT liquid crystal is more true.
the color of TFT liquid crystal is more trueTFT liquid crystal display is characterized by good brightness, high contrast, strong sense of hierarchy and bright color.
however, it also has the disadvantages of high power consumption and high cost.
TFT liquid crystal technology accelerates the development of color screen of mobile phones.
many of the new generation of color screen mobile phones support 65536 color display.
some even support 160000 color display. At this time, TFT has high contrast, The advantage of rich color is very important.
the color is richThe main components of TFT type liquid crystal display include: fluorescent tube, light guide plate, polarizing plate, filter plate, glass substrate, alignment film, liquid crystal material, thin mode transistor, etc.
TFT turns white.
power consumption, poor viewing angle, low brightness contrast! AMOLED has bright colors and large viewing angle, saving 20% of power compared with ordinary TFT, but it doesn't look as fine as TFT and has defects! AMOLED is a new generation of display technology! AMOLED.
