your budget is too much low so you can't go for lcd led but you can buy TFT
They are nearly the same. Both have a liquid crystal display screen. The only major difference between the two is that older or less expensive sets use a fluorescent lamp for the backlight, while an "LED" set uses a bank of light emitting diodes.
The LED backlighting uses less electrical power than the fluorescent lamp. There are two versions, "edge" lighting and "full matrix." Edge-lit sets can be very thin. Full matrix sets allow for "local dimming," which can bring improved contrast in specific areas of the screen.
However, don't look for a *major* difference in picture quality. The HD picture on an "LED" set will be difficult to distinguish from a very good conventional LCD set.
