Why choose OLED display module | OLED vs LCD

As we know, OLED display module is thiner than 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. let's see more OLED vs lcd screen in the following:

oled module

1. 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 dynamically dim the backlight when a low gray-scale image is presented. Nokia reports that its OLED-based mobile phones deliver equivalent perceived luminance at significant power savings in four of five usage modes. 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. 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. This advantage is also expected to enable the development of white OLEDs for lighting uses to compete with today’s very inefficient incandescent bulbs and mercury-containing fluorescent lamps. For these reasons, OLED manufacturers are beginning to become recognized as an important ‘green’ or eco-friendly product for the display and lighting markets.

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 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.monochrome oled 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.

oled vs lcd

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 manufacture in China:

For AM OLED module, China oled manufacturers have BOE, Tianma, Visionox, they are the tier 1 oled display manufacturers in China, they have the newest generation production line for oled display, that  can make the flexible oled display such as for smartphone screens. besides Samsung and LG in OLED display domain (LG is also the manufacturer of transparent oled display module), China OLED manufacturers would be the main manufatuers for oled display.

For monochrome oled panel manufacturers, there are Visionox, Wisechips, and RIT, the monochrome oled panels were mostly comes from these oled manufacturers. the oled module manufacturers such as Winstars oled, they would purchase oled panels from them. and Maclight oled is also from the similar supply chains like this.

Maclight can also custom make OLED module by custom the PCB or interface for the oled panel, and make the custom oled module for our customers.

What is OLED:oled structure

OLED (organic light-emitting display) is a light-emitting diode (LED) display, from OLED wiki, it is a film of organic compound that emits light in response to an electric current. Oled display have PM OLED (passive-matrix) and AM OLED (active-matrix), Oled emitting layer is organic semiconductor that situated between two electrodes; typically, at least one of these electrodes is transparent. AMOLED require a thin-film transistor backplane to switch each individual pixel on or off, but allow for higher resolution and larger display sizes. PM oled device without thin-film transistor layer, PM oled is mainly used in monochrome oled and small color oled display with lower resolution. AM OLED is mainly used in full color oled display module that with higher resolution, such as HD or FHD resolution that used in mobile phone or TV set.
