let me say something!
Let me say something!.. The LED backlight display is light and can be relatively thin. Life should be longer, but the brightness and gamut is not as good as cclf backlight, the picture is a little yellow. And the price will be much higher.. But because it's light, it's more suitable for notebook use... How about cclf backlight The traditional cclf cold cathode lamp backlight is better than LED backlight in brightness and color gamut. But because the structure is relatively complex (there are various optical refractors), it is relatively thick.. Because the cost is lower than led, the traditional display is more suitable.. Some people on the Internet say that led will save some power, this also needs to be questioned.. Because the luminous efficiency of cclf is already very high, it is the optical refractors of the lamp that hinder the luminous efficiency. This explains why the same 22 inch display, some manufacturers can do <45W, and some manufacturers can only do <90W.. And the LED backlight display does not have this aspect of the structure, also does not have this aspect of the problem,. However, a whole backlight is made up of many LEDs arranged in a neat matrix, because there is no optical refraction. After the display has been used for a long time, who can guarantee which led or row will not be bright or the brightness will drop? What's going to happen! Can partial picture darken discoloration (as if pure white LED used for a long time will gradually yellow said)... When it comes to the development direction of display, that is, no one can replace anyone in a short time.. LED will develop to notebook and some light and thin display. And the traditional cclf will continue on the traditional display... Don't laugh at my stupid opinion...
