As the new generation display, OLED display has more advantage than lcd display, we could see oled screen is used in smart watch, cell phone, TV display, and the other industrial display application. Oled screen is the first choice for many high-technology company when they choose the screen. Such as Apple change their Iphone screen from tft screen to OLED, and the LG OLED TV is popular in TV market. Samsung and LG are leading the OLED technology, but now, more China companies have go into the OLED display market, such as BOE, Tianma in China are the manufacturers that make oled display module.
What does OLED display means?
An organic light-emitting diode (OLED or Organic LED), also known as an organic EL (organic electroluminescent) diode, is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current.
OLED vs LCD in thickness
Active-matrix OLEDs An OLED display works without a backlight; thus, oled display is in true black levels and can be thinner and lighter than a liquid crystal display (LCD). the thickness of OLED only have 1/3 of lcd screen module. so the OLED screen can make your electronic devices as thinner as possible. such as the thinnest OLED TV from LG LG W7 OLED TV, its thickness only has 2.57mm .
OLED vs LCD in contrast:
In low ambient light conditions (such as a dark room), an OLED screen can achieve a higher contrast ratio than an LCD, the oled contrast can reach 10000:1, while a tft lcd display, its display contrast only around 800:1.
All transmissive LCD display technologies are challenged in bright sunlight, because the light reflects off the display. To mitigate the reflection, some 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, using specially designed polarizers have been specially designed to attain daylight readability in bright sunshine, but by comparison to LCDs, retain their color and contrast performance. happening with OLED technology, and it’s pretty good. Active matrix OLEDs offer the best video you’re going to see from any display technology. Their color range equals or exceeds NTSC standards. Contrast ratios in the range of 1,000,000 to 2,000,000:1 make those colors look even more brilliant. Best of all, each frame of video is crisp, as OLEDs refresh in microseconds, as opposed to LCDs’ milliseconds. In addition, there is no loss of contrast at off angles. Tech Digest recently analyzed the three competing technologies. The conclusion: in a field where the three most important criteria are picture quality, picture quality, picture quality, the writer described the result in fight terms with OLED the clear winner.
As the conclusion, for sunlight readable display, OLED would have a better display effect.
LCD vs Oled in power consumption:
Oled can emitting light by itself and no need backlight, for monochrome oled display module, 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 display panel vs LCD in 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 two years.
Will OLED get cheaper in 2020?
OLED gets cheaper, LG gets competition
And that was with just two companies, LG and Sony, selling OLED TVs in the US. In2020 they'll be joined by Vizio's new OLED TV. ... Meanwhile other brands, including Philips, Konka and Skyworth, are also bringing OLED TVs to the US this year, and they could be "good enough" too.
