Hello!
Hello! At present, the biggest difference between LED LCD and ordinary LCD on the market is the "backlight" used.
ordinary LCD uses CCFL (cold cathode fluorescent lamp) as the light source.
LED LCD uses LED as the backlight.

What is the difference between LED LCD and ordinary LCD

compared with ordinary LCD, the advantages of LED LCD are mainly reflected in the following three aspects:1、 The thickness of LCD with LED backlight will be further reducedThe thickness of LED screen notebook panel is about 1 / 2 of that of common CCFL screen.
the thickness of LED screen notebook panel is about 1 / 2 of that of common CCFL screen2、 It has longer service life.
lower power consumption and more environmental protectionThe service life of LED is as long as 100000 hours.
even if it is used continuously for 10 hours every day, it can be used continuously for 27 years.
after using LED backlight system.
the energy consumption can be greatly reduced, which is 48% less than that of the common CCFL LCD.
moreover, the LED does not use mercury, which is harmful to the environment.
it is quite environmentally friendly, and CCFL contains mercury.
in addition, the LED has no mercury, which is harmful to the environment3、 The color performance of LED backlight screen is much better than that of CCFL.
the color performance of LED backlight screen is much better than that of CCFLThe original CCFL backlight has some problems such as color purity and so on.
its poor performance in color scale leads to LCD's inferior to CRT in gray scale and color transition.
according to the test.
using CCFL backlight can only achieve 78% of NTSC color area, However, LED backlight can easily obtain 100% NTSC color area.
in terms of color expression and color level transition.
LED backlight also has significant advantages.
.
LED backlight has lower power consumption, brighter color and higher contrast, which is better than CCFL backlight? Let's use GTS250. Now the cost-effective graphics card hardware specification is GTX250 * 2=gtx260The GTX250 is about 7000 points in 3dmark V performance mode, and the gtx260 is about 12000 points.
the results show that the GTX250 has a good performance in 3dmark V performance modeHowever, it depends on your CPU.
to be honest, if the CPU is not i7, it's very wasteful to use gtx260 graphics card, so you can use e8400, E7400, Q8200, and GTS250.
the cost performance is more appropriate.

.
in general, you can use e8400, E7400, Q8200
