Advantages of OLED displays:
Oled display can be developed in more display ways than lcd display module. such as transparent Oled display module, Flexible oled display module etc, Oled display bring the better display performances 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.
OLED display module is thiner than traditional 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 display module is better 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. 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.
OLED televisions present even greater savings. Independent tests show that OLED televisions consume 40% to 50% less power and deliver a higher quality image than their LCD equivalents.But for white or very light images, OLEDs still consume more power than LCDs, but with continued development of new materials and display designs, the OLED power consumption advantage is expected to grow.
2. LCD has a longer lifetime vs OLED, but oled life time is better and better now:
OLEDs are emissive, similar to plasma displays and cathode ray tubes. They degrade over time. after 50,000 long working hours, the oled screen display brightness might be decreased around 20%~50%. the LCD panel has not such problem, a siganificent LCD panel life time can be more than 50,000 hrs to 10, 000+ hours.but the LCD module with backlight unit, its lifetime is upon the backlight LED of the lcd module, becausetransmissive lcd displays that operate by filtering a backlight. LCD module life time typically last as long as their backlights, which also degrade over time or can fail catastrophically. Early in the development of OLED displays, the oled 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 on oled manufacturers, OLED displays have lifetimes comparable to or better than LCDs. Many OLED displays manufacturers make their OLED currently on the market have lifetimes exceeding 50,000 hr nowadays.
3. OLED has better contrast and viewing angle than LCD:
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.
Monochrome oled display module 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.
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, As the latest news that iPhone 12 screen would return from OLED to Lcd screen. many oled manufacturers is also developing the new display mini-led for the next generation display.
4. OLED has better display performance in wide temperature working vs LCD:
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 display module is better for sunligh readable display vs LCD:
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 display module has fast reflesh time vs LCD:
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.
