LCD is a passive display device, the need for other light sources (backlight) irradiation, through the CF, LCD glass, polarizing films, polarized light, the use of a variety of polarized light, the LCD display is a passive display device, the display of the specific pixels of self- In order to achieve display.


LCD is limited to the aperture ratio and the 5 layer optical structure of the two main reasons, its transmittance is always over 10%, to 7% is very good, so the LCD to get higher brightness, It is necessary to improve the brightness of the backlight itself, that sacrifice a lot of power in exchange for the brightness of the upgrade, which now LCD brightness is difficult to more than 1000 lumens, the contrast is difficult to exceed 1500 main reasons. OLED and there is no such restrictions, it can achieve high brightness contrast, easy to reach 3000, which is far from a level.


But also because the display principle is not the same, OLED can achieve higher efficiency than the LCD, a better perspective.
