Advantages of OLED displays:
Oled display can be developed in more display ways tha
n LCD display module, such as transparent OLED display module, Flexible oled display technology. OLED display bring the better display performance than other displays. OLED display module has many advantages in contrast, brightness, and thinner than LCD display, we can get more vivid
display image by using OLED display, OLED display doesn't require the backlight unit, it is better for making transparent OLED display and flexible OLED display module.
ditional LCD display, because OLED screen no need the backlight unit, it can emit light by itself. Besides the thinner, OLED screen could be made in flexible, the newest fexible screen all are made by oled module, because low-temperature processing oled emit light materials can be evaporated to the flexible subplated, while tft lcd screen can not make it like that, because the liquild crystal have to be sealed inside the tft lcd cell, the flexible subplated can not provide a reliable sealing condition for flexible tft lcd screen.

1. OLED vs lcd: Oled display module in power
consumption:
Oled can emitting light by itself and no
need backlight, through the use of phosphorescence (which can convert four
times more electricity into light than other materials), OLEDs are
significantly more power-efficient than LCDs. In fact, LCD manufacturers are
trying to replicate the power advantages of OLEDs by using LEDs in some
high-end TVs,
To oled display module, especially for
monochrome oled, its power consumption is related to the display content,
the less display content, the lower power consumption. Such as an 0.96” oled
128x64 pixel, with SSD 1306 IC driver, I2C oled interface, the current for full
display on would be 12.3 mA, and the current for 50% display pixles on would be
7.3 mA. These current is included the OLED driver’s current and oled display
screen’s current. The oled power consumption would be also related to the
brightness level what it is on working, the higher brightness means higher driver
voltage, higher current and higher power consumption.
2. OLED vs lcd: OLED display module lifetime:
OLEDs are emissive, similar to plasma
displays and cathode ray tubes. They degrade over time. LCDs are transmissive
displays that operate by filtering a backlight. LCDs typically last as long as
their backlights, which also degrade over time or can fail catastrophically.
Early in the development of OLED displays, the lifetime (defined as the time it
takes for the display to reach 50% of the original luminance) was lower than
typical LCD lifetimes. However, with tremendous progress in materials
development, OLED displays have lifetimes comparable to or better than LCDs.
Many OLED displays currently on the market have lifetimes exceeding 50,000 hr.
In addition, lifetimes for OLED materials being developed by Cambridge Display
Technology, Universal Display and others have lifetimes 2-3 times greater than
typical LCDs. Some are in products today and more are expected to reach the
market within coming years. Such as Maclight 0.96” oled in white color, its
lifetime can be 50,000 hours in 60cd/m2 brightness display. But the higher
brightness of OLED, its lift time would be decreased accordingly.
OLEDs offer great potential for efficient
lighting solutions with recent reseach achieving 46 lumens per Watt (lm/W) with
lifetimes greater than 10,000 hr (a standard incandescent bulb offers 14 lm/W
with a 1000 hr lifetime).
3. OLED vs lcd on contrast and viewing
angle:
More peoples concern that
OLED has high display contrast and can get more vivid display colors than lcd
screen, the oled contrast can reach 10000:1, while a tft lcd
display, its display contrast only around 1000:1. because OLED has a more
blacker background in the non-display area, while to the lcd screen, it has
more or less light leak on the non-display area, it lead to the lcd display can
not get a better display contrast than OLED display module.
To monochrome oled
display module, it is correct. Monochrome oled have higher contrast than monochrome lcd, because its
background is more blacker than monochrome lcd, monochrome oled background
without light leak as monochrome lcd, so its contrast is better than
monochrome stn lcd or TN lcd
display. and the monochrome lcd (STN lcd or TN lcd) has the viewing angle
limited, its viewing angle is 120° (max), but oled screen could be 180°, that is without viewing angle limited.
To color AM oled display module, AM-OLEDs offer the best video you’re going to see from
display technology. Their color can reach higher NTSC standards. Contrast
ratios in the range of 1,000,000 to 2,000,000:1 make those colors look even
more brilliant theoretically. But in fact, as the IPS LCD or
LTPS TFT LCD technology are going to mature, the color tft lcd screen is almost
near to the color oled display module in viewing angle and contrast in display
performance nowadays, please see the comparision picures as below, we use IPS
tft lcd vs OLED module as below, because IPS tft has the outstanding
performance in viewing angle, then you can the ips tft lcd is almost has
similar display performance as the color oled display (of course, AM-oled is
still little better in wide viewing angle, but not so much). but the cost of
oled screen are 2~3 times than tft lcd screen, so for color display, we don't
think it is necessary to choose oled display. for tft lcd module, the tft lcd
glass and backlight can be made more thinner than before, its thickness can be
almost similar nowadays.
4. OLED vs LCD in wide temperature
working:
Oled moduel have outstanding performance
than lcd screen, even both oled module and lcd display module said they could
support -40~+85°C in their datasheets,
but the lcd screen always would be slightly dimmer in low temperature and
fading in high temperature, it is limited by the liquild crystral
characteristics, but the oled module display performance would be consistency
in high temperature and low temperature working.
5. Oled module is better for sunligh
readable display:
All transmissive LCD display technologies
are challenged in bright sunlight, because the light reflects off the display.
To mitigate the reflection, the LCDs offer a transflective mode, which is a
combination of a reflective and a transmissive display, to lessen the problem
but compromise on color and contrast performance in the process.
OLED displays, because it has a blacker
background in non-display area, and by using specially designed polarizers,
oled attain better daylight readability in bright sunshine, OLED display
has better retain their color and contrast performance than lcd.
In the same time, OLED module has better
wide temperature than lcd screen, it has without the response time problem when
in low temperature and display fade in high temperature as comparing to lcd
screen. so oled module is more suitable for sunligh readable display.
6. Oled module reflesh time:
OLEDs refresh time is in microseconds that
with faster response time, as opposed to LCDs’ milliseconds. In addition, the
oled reflesh time would be same in high temperature and low temperature. while
to lcd screen, it reflecsh time would become slowly in low temperature.
Oled module manufacturer in China:
China OLED panel manufacturers have BOE, Tianma, Visionox, EDO, they are tier 1 OLED display
manufacturers in China, they have the newest generation production lines for OLED display panels, making AM-OLED panels and flexible OLED displays, such as for
smartphone screens. Besides Samsung and LG in OLED display domain(they are also
the manufacturers of transparent oled display modules), China OLED manufacturers
are the major manufatuers for OLED display panels market.
For monochrome OLED panel manufacturers,
there are Visionox, Truly, Wisechips, and RIT, Winstars in Great China area, monochrome OLED panel sources are mainly comes from these OLED panel manufacturers.
Besides OLED panel manufacturers, OLED module manufactures are more common than OLED panel manufacturers, The processes of OLED module production are most likely to COG LCD module production, only without backlight assembly. The small OLED display module intergrate OLED panel, IC driver chip on glass, flex cable, sometimes with PCB adapter. The interfaces of small OLED display modules are available in IIC, SPI, MCU, MIPI interface, that they are easily to be used in common master board, such as Raspberry PI, Arduino, STM32, ESP8266.
