Company News >> Going into the world behind the glass: the advantages and disadvantages of LCD and OLED 19th,Dec,2018
                                            We all know that the screen is nothing more than two (depending on the principle of illumination): LCD and OLED, and the principle of LCD illumination is that the backlight is energized to make the liquid crystal emit light to illuminate the screen. The principle of OLED illumination is from red, blue and green. Lights up to display an image. Both LCD and OLED have their own advantages.

The OLED screen can not emit light because the pixel is self-illuminating, so that the OLED contrast can reach a relatively high value, and the LCD is illuminated by the backlight, and the brightness can be very high.

Because the OLED self-illumination factor image shows high saturation, which is why OLED screen mobile phones are popular, but the shortcomings are also obvious. OLEDs have also been criticized in the early days because of the inaccurate restoration of white, often yellow Screen phenomenon, white reduction is not accurate, which is precisely the advantage of OLED rival LCD.

Going into the world behind the glass: the advantages and disadvantages of LCD and OLED

LCD screen is the most common screen on mobile phones. LCD has its own advantages such as high brightness, accurate color reproduction, wide viewing angle and low cost. Early TFT screens were used to display certain images. There is light leakage, and this is precisely the strength of the opponent's OLED screen.

Neither LCD nor OLED can escape the calculation of PPI [pixel density per inch]. The pixels of the LCD screen are standard RGB arrays, while some OLEDs are Pentile arrays, because in the self-illuminating red, blue and green colors. The blue life is short. In order to extend the life of the blue pixel, the blue pixel area can be increased and the green pixel area can be reduced. The OLED screen is a pair of red and blue pixels sharing a green pixel point, so that the current AMOLED screen is only an IPS screen. Two-thirds of the PPI value.

In general, both OLED and LCD are very good in the current market. The previous shortcomings were just complementary, and now both materials have solved their own shortcomings due to advances in technology.
