OLED: Organic Light EmitTIng Display, that is, organic light-emitting display, which is a newly emerging category on the LCD of mobile phones, is known as "dream display". The OLED display technology is different from the traditional LCD display method. No backlight is needed, and a very thin organic material coating and glass substrate are used. When an electric current passes through, these organic materials will emit light. And the OLED display screen can be made lighter and thinner, the viewing angle is larger, and can significantly save power.
At present, in the two major OLED technology systems, low-molecular OLED technology is mastered in Japan, and the so-called OEL of polymer PLEDLG mobile phones is this system, and the technology and patents are mastered by the British technology company CDT. Compared with PLED products There are still difficulties in colorization. Low-molecular OLEDs are easier to colorize. Not long ago, Samsung released 65530-color OLEDs for mobile phones.
However, although more advanced OLEDs will replace LCDs such as TFTs in the future, organic light-emitting display technology still has shortcomings such as short service life and difficulty in increasing the screen size. At present, OLED is mainly used by Samsung, such as the newly listed SCH-X339, which uses 256-color OLED. As for OEL, it is mainly used by LG on its CU8180 8280.
To illustrate the structure of the OLED, we can make a simple analogy: each OLED unit is like a hamburger, and the luminescent material is a vegetable sandwiched in the middle. The display unit of each OLED can generate three different colors of light under control. Like LCD, OLED has active and passive points. In the passive mode, the cell selected by the row and column address is lit. In the active mode, there is a thin-film transistor (TFT) behind the OLED unit, and the light-emitting unit is lit by the TFT drive. Active OLEDs are more power efficient, but passive OLEDs have better display performance. Compared with LCD, OLED has many advantages. OLED can emit light by itself, while LCD does not emit light. Therefore, OLED is much brighter than LCD, with large contrast and good color effect. OLED also has no limitation of the viewing angle range, the viewing angle can generally reach 160 degrees, so that it will not be distorted from the side. The LCD needs to be lit by the background light, and the OLED only needs to be powered on by the lit unit, and the Voltage is lower, so it saves more power. OLED is also much lighter than LCD. OLED requires few materials, the manufacturing process is simple, and the cost during mass production is 20% less than that of LCD. However, the main shortcoming of OLED now is that the life span is shorter than LCD, which can only reach 5000 hours at present, while LCD can reach 10000 hours.

18650 protected batteries have an electronic circuit. 

The circuit is embedded in the cell packaging (battery casing) that protects the cell from [over charge", heat or [over discharge", over current and short circuit. 

A 18650 protected battery is safer than an 18650 unprotected battery (less likely to overheat, burst or start on fire).
