Let's talk about LCD&OLED
Many people ask us what are LCDs and OLEDs? There is a difference. . .
In this way, Hisense also has ULED, Samsung and QLED.
Here we will explain to you the differences between the two types product as below:
The basis of all LCD screens: LCD (Liquid Crystal Crystal Display),
According to the backlight, LCD can be divided into CCFL and LED. LED is a kind of LCD.
The liquid crystal (LCD) screen of the LED screen has the advantages of small volume and low power consumption, and the disadvantage is that the color performance is relatively poor.
Another type of liquid crystal, CCFL (Cold Cathode Fluorescent Lamp), has good color performance, but it has high power consumption and short life. It is not common nowadays.
OLED (OrganicLight-Emitting Diode) organic light-emitting diode can be understood as "living LED" light-emitting technology.
Other technical pixels can be understood as "dead" and require LEDs (ie, backlights) as the light source.
That is to say, unlike the LEDs projected on the screen by the three primary color lamps, the OLED allows the semiconductor material and the luminescent material to be illuminated by carrier injection and recombination under the electric field drive.
According to the driving method, OLED can be divided into passive OLED (PMOLED) and active OLED (AMOLED), which is the kind of mobile phone used this year.
Due to the "self-illumination" property, the OLED can directly control the brightness change of the pixel, and the response speed is far superior to the LED.
At the same time, because there is no bulky projection, OLED screens can be bent, curved TV, curved screen mobile phones, all benefit from the characteristics of OLED.
Of course, OLED is not a panacea. Playing the same picture for a long time will leave the OLED "burning screen" behind (for example, CCTV1 will leave the logo for a long time).
The dimming problem on the mobile phone also makes the strobe become a problem for many users.
There is also a core reason, that is, the price is expensive!
As for the future, stronger QLED (quantum dot) technology is coming, it emits light through tiny, nano-scale "quantum dot" particles.
At many levels, it is better than the existing OLED, but it is not known when it will be available.
