What's the difference between LED and WLED in LCD?
They are collectively referred to as LED. Ordinary LED emit light, there are generally 4-5 kinds of spectrum. What WLED does is white light. The white light is the kind of light emitted by a camera flash, which contains no other spectral components or is very low. WLED LCD monitors, like LED displays, have more meaning than hype. Even when welding can be made, the arc of light has no meaning for liquid crystal displays.
The liquid crystal display's earliest Cathode Lamp Fluorescent (Cold), we are used to CCFL, the drawback of this backlight is power consumption is relatively large, the price is relatively cheap. Later, due to LED brightness and other aspects of technical upgrading, and gradually introduced LCD backlight industry. The disadvantage of LED (Light, Emitting, Diode) backlight is the higher cost.As for the difference between LED and WLED you say this, these two things are a parent concept (LED), (WLED) is a sub concept of right, LED backlight display technology currently has two kinds, one is through the synthesis of LED white RGB three colors, the advantages of this approach is clarity and good color purity, disadvantage is high cost, complex driving, long response time, there is a LED backlight technology is through WLED (white Light Emitting Diode LED), this is what we usually say the high brightness white LED driver, has the advantages of simple, low cost, disadvantage is clarity and color purity exceeded.
WLED is a kind of LED, especially white light LED. On the market of conventional display standard WLED said the good point that professional anti misunderstanding, that ugly point called DT. To put it bluntly, basically, the LED backlit display you see on the street is WLED. Do you really want to buy a RGBLED desktop display below five digit RMB?......
WLED is a white backlight LCD, but white backlight is now made up of several pure color mixed into white light and the material is more pure, more environmentally friendly, and longer LED power consumption is small, so it has become the current focus respected manufacturers of products, but not in progressive color saturation.
